2018(2016)Questions

1.What’s the principle of repair?

Answer: This glass scratch repair kit adopts the principle of repair of “grinding followed by polishing”. Taking the most common type of glass scratches for example, we use 1# grinding sheet for coarse grinding then use 2# grinding sheet for fine grinding; next, we use a polishing pad and water for polishing. When polishing ends, repair is complete. If scratches are more serious, all the steps stay unchanged except that we need extend coarse grinding; if scratches are shadow, all the steps stay unchanged except that we skip coarse grinding; if scratches are more shadow, all we need is polishing. This kitis characterized by simple operation, high efficiency, a good effect, a long life of grinding sheets, and no pollution. 

2. What’s the difference between this kit and the felt wheel our factory are using? Our polishing powder can repair scratches, too. What advantages does your product have?

Our polishing powder can repair scratches, too. What advantages does your product have?

Answer: This glass scratch repair kit consists of two grinding sheets and a polishing pad. Customers can choose the size from 2 inches, 3 inches, 4 inches, 5 inches, and 6 inches as they need. Grinding sheets of 2 or 3 inches can finish repair efficiently in a simple way; and grinding sheets of 4, 5, or 6 inches is excellent in repairing serious scratches or welding burns because they can expand the repair area. Cerium oxide polishing powder adopted by factories is mostly for beveling machine, and such device-specific polishing powder is used at high temperature, high pressure, and a high speed. In contrast, our polishing pad with a cerium oxide coating specially designed for manual operation is used at low temperature, low pressure, and a low speed, simpler to operate and more efficient.
Facing scratches, the most common method factories adopt is using polishing powder for beveling machine plus a felt wheel to polish the scratch region. If scratches are a bit serious, it takes longer to polish the scratch region. Factories can only rely on polishing because they don’t have a grinding process. Polishing powder does not have a shearing force, so workers have to polish the same site for a long time in order to repair scratches there. In this case, an obvious pit, i.e. deformation, is probably left in the repair area, which can hardly be controlled. Over polishing powder used by factories, our kit containing grinding sheets has two advantages: One is higher efficiency because it can get scratches off quickly through coarse grinding; the other is that deformation is in control when out kit is used because grinding expands the scratch region. Summing up the above, using our glass scratch repair kit can repair glass scratches quickly in a perfect way.

3.Will the repair of deep scratches with your glass scratch repair kit cause optical distortion?

Answer: Most distortion is caused by pits left where serious scratches are repaired. Imagine that some part of intact glass sags. There must be obvious deformation. However, the same pit expanded in area will be quite gradual and difficult to see from the front. It might be observed when seen carefully from one side or from a nearly horizontal angle. When you use a grinding sheet of 2 or 3 inches contained in our product for repairing general or shadow glass scratches, you can hardly see deformation. Facing a bit serious scratches or welding slag and burns, you may consider the use of a grinding sheet of 4, 5, or 6 inches for repair. The larger the diameter of grinding sheet is, the bigger the grinded area is andthe better the effect of repair is. This is because a bigger grinding sheet expands the grinded area, making the repair area much gentler.
 

4.Do I need to take training before using this kit? What’s the reason the polished area looks dark? Why brightness is uneven in the polished area?

What’s the reason the polished area looks dark? Why brightness is uneven in the polished area?

Answer: To be clear, we will send a video demoing the use of this kit by WeChat. If you don’t receive this video after buying our product, you can ask for it. This 2018 glass scratch repair kit is easy to learn and operate because there are only two grinding processes and one polishing process. The first grinding process is to get scratches off; the second grinding process is to replace coarse grinding marks with fine grinding marks, for ease of polishing; the last step is polishing. The following are problems needing attention: 1. Keep the grinding sheet totally in contact with glass and not askew to avoid deformation, darkness, and fine lines after polishing. 2. Before polishing, obverse grinding marks carefully and make sure that fine grinding marks cover coarse grinding marks. These two kinds of marks are different, the former exquisite and the latter rough. 3. During polishing, add water to keep the polished area moisture. Observe the repair effect against light. If the effect is satisfactory, repair is complete; if the effect is not very satisfactory at individual sites, continue polishing till the acceptance standard is reached. 4. If the repair effect is not obvious after polishing, you should repeat coarse grinding, fine grinding, and polishing processes in cycle till the acceptance standard is reached. 5. Sometimes brightness is uneven in the repair area. This is because grinding and polishing are in place at the center but not in place around. The right solution is to ensure the fine grinding area is bigger than the coarse grinding area and smaller than the polishing area. Alternatively, you can contact our salesman in time. And we will offer guidance on phone or in WeChat video chatting to ensure you can master the usage of this kit. 

5.What’s the repair efficiency? Won’t it be a heavy waste of time to change the grinding sheet? Do you have any more efficient products?

1. This kit can repair a 5 cm long general scratch in 3–5 minutes.
2. The grinding sheet and tray both adopting magic tape are easy to change. To repair shadow scratches needs 2# grinding sheet and the polishing pad; to repair serious scratches needs 1# grinding sheet for fine grinding, 2# grinding sheet for coarse grinding, and the polishing pad. They both are simple and quick.
3.We are still working on a simpler and more efficient glass scratch repair kit which will use a kind of material excellent both in grinding and in polishing. Quick grinding requires many large particles and quick polishing requires fine grinding. To find such a material, we need keep testing. Our technical department is working in this direction. Let’s look forward to a new breakthrough!
 

6.Why water is unnecessary in grinding but necessary in polishing?

1. In the 2018 glass scratch repair kit, grinding sheets are of dry grinding type, for the sake of quickness and high efficiency. Water is not needed in grinding.
2.Unlike the 2018 glass scratch repair kit using the polishing pad, the previous kits use felt wheels plus polishing paste for polishing. After polishing, many white marks of polishing paste remain in the repair area, polluting surrounding walls or furniture, if the repaired glass is in a well-decorated room. Besides, polishing paste cannot be transported by air. To make operation easier, avoid environmental pollution, and enhance the polishing efficiency, we coat a pad in polishing powder that can be used for polishing immediately with water. Water is essential because polishing powder cannot work without it. Polishing pads offer convenience for customers who have an urgent need and who stay abroad. They can be transported to customers fast by air.

7.Can this kit repair scratches on tempered glass?

Answer: Sure, it can. In fact, it is easier to repair scratches on tempered glass. During repair, grinding makes temperature at the grinded area rise gradually. Untempered glass may burst when heated to a certain degree. But tempered glass won’t burst because it is more tolerant towards the temperature difference between cold and hot. Thus, we say it’s easier to repair tempered glass. Pay attention to temperature control when you repair untempered glass. Stop operation before glass is too hot to touch. Do not continue until glass temperature drops to room temperature.

8.Does repair destroy the stress of tempered glass? Will glass detonate?

Answer: Tempered glass detonates spontaneously due to the stones, crash, or nickel sulfide crystals inside or due to bursts and deep chips. Scratch repair does change itsthickness but such change is not so serious as the above causes of spontaneous detonation. Consequence unknown, the repair of very serious burns (e.g., the depth of burn is one quarter of the glass thickness) is an exception. For this reason, repairing general scratches is safe, without an impact on the stability of tempered glass. Please feel free to use the kit.   

9.What are limits to the length and depth of scratches it can repair?

Answer: 1. This kit adopts the principle of repair of “grinding followed by polishing”. Grinding has two steps: coarse grinding and fine grinding. Coarse grinding, which fine grinding and polishing follows, is to get scratches off. Since the sheet for coarse grinding has big grinding particles, the grinding efficiency is very high. Taking an example, a 5 cm long scratch left by a stones or sand can be got off basically in 1 minute. Facing more serious scratches or burning by welding slag, you need only extend coarse grinding before fine grinding and polishing. Thus, the kit can repair all scratches no matter how serious they are.
2. The kit can repair all scratches no matter how deep they are. Not to mention the length. If scratches are too long, we advise you repair them in segments.

10.How many square meters of scratches can a kit repair?

Answer: In most cases, scratches on glass are distributed irregularly. A piece of glass may have one scratch or several. Even if there are multiple scratches, it is not necessary repairing the entire piece of glass because that solution is not so cost-effective as replacing. Plus, scratches differ in depth. Anyway, such unit of measurement as square meter is false. We can only introduce the depth of cut left by another piece of glass or by sand. For a 5 cm long general scratch (left by another piece of glass or by sand), a kit (1 coarse grinding sheet, 1 fine grinding sheet, and 1 polishing pad)can repair more than 10 scratch point (each point is roughly priced at RMB 2.7). However, its ability to repair serious scratches like burning by spot welding slag cannot be estimated because both severity of scratches and the acceptance requirement are unknown.

2008(2004)Questions

这套玻璃划痕修复工具的修复原理是什么?和现在我们工厂里面用的抛光粉有什么不同?

答:我们这两套玻璃划痕修复工具的修复原理就是研磨加抛光。和您工厂里面现在用抛光粉修划痕有着质的不同。不同点体现在以下2个方面:
1, 目前大多数玻璃加工企业对于划痕的修理办法基本就是用羊毛轮加氧化铈抛光粉(那种砖红色的抛光粉)进行抛光,如果修复的划痕比较浅,采用这个办法修复还是有效果的,但是耗用时间比较长,一般十几分钟到几十分钟,并且在修复结束后会留下一个比较明显的凹坑,有可能在正面都可能会看到。原因就是抛光粉的剪切力比较低,想尽快的将某个位置的划痕修掉,就要比较长时间的停留在那个位置研磨,所以修复后在那个位置就会出现凹坑。因为这个修复位置的玻璃厚度突然比旁边的玻璃厚度要降低,所以凹坑就明显了。但是我们的专业型玻璃划痕修复套装(或者是基本型玻璃划痕修复套装)就能有效的控制这个问题。我们在修复划痕之前,首先要了解验收标准,直视不能发现变形和45度角以内不能发现变形的修复方法是不一样的;对于一条划痕来讲,它的深度是固定的,不管是10微米还是50微米,我们要想修复划痕就要研磨到这个深度,研磨的区域越大,修复的划痕位置的变形就会越小,就不会是突然间出现凹坑,而是很平缓的从浅到深的过渡。具体操作方法就是:确保可调速角磨机的档速是在1档上,使用绿色磨片,粘在相应的研磨底托上,磨片要与玻璃充分、完全接触,不要倾斜,注意喷水,经常查看研磨情况,研磨一会儿就擦干净,透过光查看划痕是否被研磨掉了,如果没有,继续研磨,直到划痕被研磨掉为止。当查看到划痕被研磨片研磨掉后,换粉红色磨片,研磨的区域要将绿色的研磨区域覆盖掉,并比绿色研磨区域扩大出5mm~10mm,以此类推,注意观察研磨情况,一定要全部将前一道的研磨痕迹覆盖。最后进行抛光。第一次的研磨是为了将划痕去除,接下来的研磨是为后面抛光打基础,同时将划痕的位置有效的展开了,然后抛光。如果是深划痕,修复的要求比较高,可以将研磨的区域扩展的更大,扩展的研磨区域越大光畸变越不明显,当然,成本也相应的增加。我们的抛光膏不同于前面提到的砖红色的抛光粉,我们这种抛光膏有着很强的剪切力,抛光很快。经过以上几个程序,一个划痕就修复完成了。
2, 如果是一个比较深的划痕,一般就会因为没有办法修或者因花费工时太长而放弃,整块玻璃就报废了。而我们的这套划痕修复套装是使用分级的研磨办法,第一级的磨片比较粗,是35μ的,可以很快将划痕磨掉,不管是多深的划痕,在我们的修复视频上可以看到,最深的划痕是由36目的砂轮片制造的,是一般情况下玻璃厂里面很不容易产生的。经过粗磨、精磨、抛光以后,划痕的位置又恢复到了明亮如新。所以,对于我们这两套产品来讲,无论任何划痕、瑕疵都是完全修复的。

玻璃划痕修复以后会有光学畸变吗?

答:根据实际情况不同畸变会有不同。
首先我们来判断划痕的深浅,判断玻璃划痕深浅的标准(以大多数情况为参考):
1)毛道:在特殊的角度下眼睛才能看得到,用手触摸不到的划痕;
2)浅划痕:眼睛能看得到,手指肚感觉不出来,只能用指甲感觉得出来的划痕;
3)深划痕:眼睛能看得到,手指肚能感觉得出来的划痕。
1, 毛道修复,不会产生光畸变:
相对于毛道就比较容易修复,我们直接使用抛光膏进行抛光即可将毛道修复,并且不会造成光畸变。因为毛道的深度比较浅,抛光膏对于划痕处玻璃的磨削量比较小,并且磨削量小,很容易控制,所以不会造成光畸变。
2,浅划痕,不会产生光畸变:
浅划痕要先对划痕进行判断,尽量首先使用颗粒度低的磨片。颗粒度越低的磨片对于玻璃的磨削力越低,对于玻璃的变形越容易控制,同时可以选用2寸或3寸磨片,扩大研磨区域,以降低单位面积内变形程度,如果控制得当,如果控制得当,是不会发生变形的。。
3, 深划痕修复,可有效控制畸变。

如果是深划痕,修复的要求比较高,可以将划痕的区域展开,展开的面积越大,修复后的变形就越不明显。原理是:在某一个位置上的玻璃被打磨掉后,这个地方的玻璃的厚度就会小于它的周围的玻璃的厚度,划痕多深,修复结束后,在那个区域的玻璃就会被研磨掉多大的厚度。如果是50微米深度的划痕,修复结束后,在划痕所在的那个区域内,玻璃厚度就会减少50微米。在直视的时候不会感到差异,但是在小于45度或30度、对着光线观察的时候,必然在光的反射上会和没有修复过的地方产生差异,也就是光畸变。不是我们公司的这套产品做完会产生光畸变,所有采用研磨办法进行划痕修复的划痕修复产品都是一样的,会在修复结束后留下变形。但是通过使用我们这套产品是可以有效控制变形的,扩展的研磨区域越大光畸变越不明显,当然,成本也相应的增加。

你们的这套修复工具修完深的划痕会有变形,那我们怎么交货呢?

答:我们公司生产的玻璃划痕修复套装对于毛道、浅划痕的修复可以达到满意的效果(45度角以上看不出来),对于深划痕,通过使用我们的玻璃划痕修复套装内的3寸研磨片来研磨,变形是可以控制的,修复的效果也可达基本达到满意(正面看不出来)。如果您产品的目标客户是建筑、门窗、装饰行业的,那我们公司生产的玻璃划痕修复套装将完全适合于您,因为这些客户的验收标准一般不会很高。如果您是为电子行业做配套,无论是否出口,都将面对严格的检验,对于高要求的修复效果我们也是可以满足您的要求,一般我们会采用3寸的金刚石颗粒度较小的研磨片如蓝色研磨片、橙色研磨片来研磨,最后抛光。因为此类研磨片金刚石颗粒度小,切削量也小,比较容易控制变形,将划痕研磨掉后,最后进行抛光。这样不容易造成变形、并且能有效减少废品率和提高不良品的修复效率。
我们的产品不是百分之百优秀的,但是我们承诺:
1,只要是玻璃材质上的任何划痕、瑕疵都可以修复;
2,毛道、浅划痕可以高效修复,修复后基本没有变形;
3,深划痕通过3寸研磨片来研磨也是可以有效的控制变形;

4,修复工作需要手工完成,操作前请先阅读使用说明及观看演示视频。

你们这套划痕修复套装修复的效率高吗?经常要换磨片,那不太浪费时间了吗?有没有一种东西就可以特别有效的呢?

答:1,一条5厘米长的一般划痕,我们大概5分钟到10分钟可以修复;
2,更换磨片就是一秒、2秒钟的时间,磨片是背面带胶的,粘到研磨底托上就行,不会花费很长时间,而且您可以根据实际情况选择磨片的使用,该用哪种用哪种,在恰当的环节上使用恰当的磨片,在研磨程序做得非常充分的前提下,抛光也会非常容易的,总的来看还是节约了时间的,前期的研磨工序处理的好,划痕越严重,节约的时间就越多。

3,简单又高效的玻璃划痕修复产品我们也正在努力研发中。但是,既有很强的研磨能力同时还具备优异抛光效果的玻璃划痕修复产品还真是不太容易研发,最大难题在于研磨和抛光之间很难平衡,研磨快就要求颗粒大而多,而抛光好就不能存在颗粒,我们公司技术部正努力的朝这方向前进,期待有更新的科技突破!

为什么必须在研磨、抛光过程中要加水?我没有加水,也能磨,但是效果不好,为什么?

答:水流在研磨过程中有3个作用:
1, 对玻璃和磨片降温,在研磨过程中玻璃会因为研磨而发热,适当加水会为玻璃有效降温,防止玻璃过热而炸裂;另外,磨片也不能过热,过热会导致磨片上的金刚石颗粒同磨片分离,影响研磨效果和磨片寿命;
2, 冲刷研磨过程中的玻璃粉末,研磨过程中研磨片和玻璃摩擦会出现很多玻璃粉末,应该及时清理,最好的办法就是用水进行冲刷,及时冲刷,有利于确保是磨片的颗粒在对玻璃进行研磨,而不是研磨刚刚研磨下来的玻璃粉末;同时对划痕修复进度可以及时了解;同时还能防止过度研磨而导致的磨片浪费;
3, 增加剪切力,没有水有时磨片会在玻璃上打滑,起不到很好的研磨作用;
抛光过程中加水的目的是降温和及时调和因玻璃温度上升而干燥的抛光膏。

在没有水的情况下磨片也能研磨,但是
1, 研磨下来的玻璃粉末不能及时、有效的清除,造成的后果就是降低研磨效率和磨片的浪费;
2, 不能控制玻璃和磨片的温度,造成玻璃炸裂的危险和使磨片上的金刚石颗粒脱落,造成浪费;

3,由于没有水的降温,由于温度过高,玻璃很容易变得无法接触,严重影响修复效率。由于以上几个原因,虽然不用水可以研磨出玻璃粉末,但是这样是无法完成修复的。

钢化玻璃上的划痕可以修复吗?

答:完全可以。所有玻璃材质上的划痕都可以修复。钢化玻璃比普通玻璃硬5~6倍,研磨、抛光的时间比修复普通玻璃时间长些,相应的,浅的划痕修复快些,深的划痕修复的慢些。

钢化玻璃修复后会破坏钢化玻璃的应力吗?玻璃会爆掉吗?

答:玻璃钢化以后发生自爆的主要原因是由于玻璃中的结石、杂质、硫化镍结晶物或炸口、深爆边等造成,虽然钢化玻璃经修复划痕以后在厚度上会有所改变,但远不及以上造成自爆原因的程度严重,所以,一般的修复划痕对于钢化玻璃的稳定性是不会造成影响的。是非常安全的,请您放心使用!

你们这套产品我们怎么购买?

答:购买我公司产品有如下三种方式:
1, 电话订购,欢迎来电:
电话:022-88230488/83776480
业务电话:18602693070
2, 在线订购:
客服QQ:138200930
技术QQ:1305855640
网络QQ:138006302
或者在网站页面“在线订购”下订单。“在线订购”,登录我公司网站,点击导航栏上的“关于我们”,打开“在线订单”页面,然后填写您所要购买的产品内容以及您的收货信息,包括收件人姓名、联系电话、收货地址以及发货方式,我们会在第一时间和您取得联系,和您进行确认,汇款后请来电话并传真汇款回执至我公司,查到您的款项,我们会尽快给您安排发货。
3, 网店购买:我们公司在淘宝开有网店,请登录:uerglass.taobao.com。可以在我们淘宝网上的店铺里面拍。我们根据您提供的物流或快递公司给您发货。

目前我们有两种发货方式:一、款到发货:运费由客户承担,因为有些快递运费到付比现付运费费用要高,我们建议您把货款与运费一起汇款到我公司,快递运费现付,这样可以节省一些费用,也可以选择物流发货,运费低些。二、代收货款:代收货款业务目前合作的仅有物流,运费及代收货款手续费均由客户承担。我们长期合作的快递有:顺丰快递、天天快递、圆通快递等等,长期合作的物流有:佳吉物流、德邦物流、天地华宇物流等等。

我们这个地方大概多长时间可以到货?

答:快递一般比物流要快,而且是送货上门,当然运费也比物流要稍微贵些,但如果您着急使用产品,我们建议您选择使用快递发货。物流发货需要自提,而且速度是比较慢,对于货物本身也不安全(有时个别的物流公司管理不太规范,造成过货物损坏、遗失)如果您不着急使用产品,而且方便去提货,选择物流发货也是比较节省费用。请您汇款后务必要与我们电话联系并传真回执,因为我们每天都有很多笔相同或相似的款项入账,也没办法区分哪笔款项是您的。所以,我们在确认收到您的款项后将在第一时间内安排发货。快递发货,一般情况下,(由于我们的产品里面含有抛光膏,不能走空运,只能走快递公司的陆运)所以离天津较近的地区估计2~3天可以收到货,离得较远的地区估计4~6天可以收到货。物流发货,一般情况下,离天津较近的地区估计3~4天可以收到货,离得较远的地区估计5~8天可以收到货,如果需要中转才能到达的地区,时间会比更长。如果快递或者物流无法到达的地区,我们将发EMS,发EMS的产品需先汇款。

听说有一种药水,轻微抹到划痕的地方划痕就消失了,你们有这个东西吗?

答:经常听有客户这样问的,但是我们从事玻璃行业十几年了,并且也经常参观行业展会,到目前为止还没有亲眼看见过这样的产品。
1,据我们所知,在化学试剂里面只有氢氟酸可以轻易将玻璃腐蚀,以前也有玻璃工厂用过含有氢氟酸这种腐蚀性极强的产品做过无反射玻璃的,但是那种工艺现在早就淘汰了,一方面危险性极高,另外也不环保,所以现在制造这种玻璃已经早就改用更科学、更环保的办法了。如果能有和玻璃划痕发生反应的化学方法我们认为也只有类似氢氟酸这种化学试剂了,但是氢氟酸在和玻璃划痕发生化学反应的同时不可能对划痕周边没有影响,就算把划痕腐蚀掉,但在这个液体的所到之处必定留下新的痕迹,所以我们认为在玻璃划痕的地方用化学方法把划痕抹下去,而且划痕周围不受影响,还完好如初,对这一点我们表示怀疑。但如果真有这样的产品,那真是所有玻璃行业、玻璃深加工行业、家具行业和汽车维修行业最大的幸事。
