挡风玻璃修复
汽车大镜的重要性
机动车安全玻璃（Automotive Safety Glass，俗称汽车大镜）的安全问题往往被大多数车主忽视。汽车制造商在广告中常强调车辆的安全性能，但对于挡风玻璃及其功能的介绍却相对少。
传统的认知只是防止风，雨水和飞行碎屑（如昆虫和石块等）进入车厢内。实际上，汽车挡风玻璃具有多种功能，除了为车厢和安气囊提供结构支撑，防止车厢坍塌及乘员在事故中被甩出车外。
不同类型的车辆使用的玻璃厚度因其用途而异。一般而言，小轿车的玻璃厚度约为4.8mm左右，而巴士的玻璃厚度则大约在10mm左右。这是因为巴士的车镜较大且中间没有骨架支撑，再加上需要面对风的阻力和压力，因此需要更大的厚度和更坚固的结构。
汽车安全玻璃要有两种类型，一种是夹层玻璃，用于前挡风玻璃，另一种是钢化玻璃，用于 后窗和侧窗。 夹层玻璃是由两片玻璃夹着一层名为聚乙烯醇缩丁醛（PVB）的塑料中间膜堆叠而成。夹层玻璃虽然容易破裂，但它可以防止碎片在碰撞中飞溅，因此可以避免造成对乘客伤害。这种玻璃同时能承受极端的撞击而不会被异物穿透，提高乘客的安全性。即使夹层挡风玻璃有轻微破损，如小缺口或裂缝，也可以进行修复。 另一种类型是钢化玻璃。它比其他标准玻璃更坚硬、更结实，通常强度是普通玻璃的十倍。钢化玻璃一旦破碎，会变成成千上万块不锋利的碎片，即使掉到人身上也不会造成严重伤害。然而，遗憾的是，一旦破碎，钢化玻璃无法修复，唯一的解决办法是更换。钢化玻璃主要用于汽车行业 的后窗和车门窗。

玻璃裂痕的种类
靶心/牛眼（Bull's Eye）石头印
Damage marked by a detached cone on the outer glass layer resulting in a dark circle with an impact point.
这种类型的挡风玻璃损伤通常呈圆形。裂缝的冲击形状明显 — 就像靶心一样。
如果不及时处理裂缝，过多的灰尘、油脂和其他杂质可能会在受损区域积累。
这使得损害更加严重，修复裂缝变得非常困难。
如果得到及时修复且由专业技术人员进行修理，裂缝将不会留下任何痕迹，您的挡风玻璃将变得光滑如新。
半月形
半月形裂纹与牛眼裂纹类似，但有一个关键区别，即损坏不是完整的圆形。与牛眼裂纹不同，牛眼裂纹是由更强力的冲击引起的。
半月形裂纹通常是由钝物引起的。这种不规则的形状使技术人员在清洁和修理挡风玻璃时具有更大的灵活性。
星形裂缝
星形裂缝的损害表现为从冲击点开始的一系列短而激进的裂缝。
冲击引起的损害在某种程度上类似于星星。通常，当汽车挡风玻璃受到碎屑或其他物体的打击时，裂缝最初是小的。
组合裂缝
当汽车挡风玻璃受到石子或碎屑的损害时，可能会出现星形裂缝和靶心石头印的混合。
这种类型的挡风玻璃裂缝损伤称为组合裂缝。这些裂缝非常难以处理。
组合裂纹产生的原因类似于其他裂缝。
需要注意的是，修复组合裂缝需要高技能的技术人员。否则可能会导致挡风玻璃进一步受损。
边缘裂缝
边缘裂缝通常是由于长时间暴露于高温下造成的 — 这在马来西亚并不罕见，因为阳光加热了玻璃周围的金属和材料。
因此，挡风玻璃的边缘比中间部分更加高温。这种温差可能导致玻璃边缘在受到外力冲击后出现裂缝。
虽然最初很小，但它可能会变得更大，长达25-30厘米。然后，这将成为一个严重的问题，挡风玻璃将需要立即更换。
大镜中心裂缝
类似于边缘裂缝，但始于挡风玻璃的中部。
它们以不同的形状出现，同样是由大镜受外力冲击后温度波动引起的。
中心裂缝然后可以从挡风玻璃中间蔓延到边缘。如果您注意到裂缝看起来像飘移裂缝，最好尽快咨询挡风玻璃维修专家，以防止裂缝蔓延到整个挡风玻璃！
玻璃表面坑洞 (Surface Pit)
与正常磨损有关的表面小坑，不会穿透塑料夹层。
挡风玻璃的自然耗损通常是由道路上的沙子、灰尘、小石子和其他碎片造成的。这些颗粒比导致裂缝和碎裂的物体小得多，但随着时间的推移，它们会积聚并造成损坏。
挡风玻璃维修流程
Let’s check how bad the damage to your car’s windshield is. If it’s just a small crack or chip, you might still be able to drive with it, but it’s best to fix it soon at a glass shop with price as low as RM80. But if the windshield is really cracked or broken, you need to replace it right away. Don’t worry, our experts will check it for you and tell you what to do.
For minor damage such as small cracks, repairs can be done using the resin injection method. This process involves injecting a special resin into the crack or fracture, then curing it with ultraviolet light. Repairs using this method can restore the glass strength to up to 90% and prevent further damage.”
If a trained technician assesses that the windshield crack can be repaired, they will prepare the area around the damage for repair. This includes protecting the car bonnet and cleaning glass fragments around the cracked area of the windshield.
First, a Vacuum Pump is used to remove air from the crack in the glass. Then, a Clear Adhesive is used to fill the crack. This adhesive is cured under UV light. After repair, the windshield will have about 90-95% of its original strength.
Although minor repairs can be done, there are some conditions that require you to completely replace the windshield, namely;
- Too long or wide cracks: Cracks that extend over a large area can obstruct visibility and are difficult to repair.
- Too many chips: If there are too many small chips, repairs will not be effective and can cause further damage.
- Severe damage to the coating layer: Damage to the coating layer can cause distortion in vision and reduce visibility.
