If you are just starting to do hollow glass factory, or do not want to use two-component glue machine operation, want to use the manual to do, then hollow glass manual scraping how to operate, from the type and structure of glue to explain the operation.

要理解的是为什么要使用双密封橡胶:

The first thing to understand is why double-sealant rubber is used:

1 .根据中空玻璃的质量要求，两种密封剂主要有聚硫树脂、聚氨酯和硅酮三大类，手动需要调整比例。

1. According to the quality requirement of hollow glass, there are three kinds of sealants: polysulfide resin, polyurethane and silicone, which need to be adjusted manually.

2. 其中大部分主要使用聚硫树脂和硅树脂，而聚氨酯在我国起步较晚，很少使用。选择适合你的胶水。

2. Most of them mainly use polysulfide resin and silicone resin, while polyurethane started late in our country and seldom used. Choose the glue that suits you.

手工刮胶的结构与组成

Structure and Composition of Hand Scraper

硅酮密封胶是指以聚硅氧烷为主要原料的一种密封胶，又称硅酮密封胶。硅密封胶的聚合物链主要由硅—O—Si组成，在固化过程中交联形成网状硅—O—Si骨架结构。Si—O键能(444KJ/mol)非常高，远远高于其他聚合物键能，但也大于紫外线能(399KJ/mol)。

Silicone sealant is a kind of sealant with polysiloxane as the main raw material, also known as silicone sealant. The polymer chain of silicone sealant is mainly composed of silicon-O-Si, which forms a reticulated silicon-O-Si skeleton structure during curing. The bond energy of Si-O (444KJ/mol) is very high, which is much higher than that of other polymers, but also higher than that of ultraviolet (399KJ/mol).

2硅酮密封胶分子结构使硅酮密封胶具有优异的耐高温、耐低温、耐气候、耐紫外线老化、吸水率低;中空玻璃的缺点是透气性高。

2. The molecular structure of silicone sealant makes silicone sealant have excellent high temperature resistance, low temperature resistance, climate resistance, ultraviolet aging resistance and low water absorption; the defect of hollow glass is high air permeability.

手工刮胶容易出现的问题:

Hand scraper problems are easy to occur:

，比例不同

First, the proportions are different.

二世。不均匀部署

King II. Uneven deployment

三、不能使胶水立即在中空玻璃上混合后，让它在玻璃上完成初硫化完成硫化的过程

3. The glue should not be mixed on the hollow glass immediately, so that it can complete the process of initial vulcanization to complete vulcanization on the glass.
