中空玻璃打膠機手工刮膠怎么操作？
如果你是剛開始做中空玻璃廠的，或者不想用雙組分膠機操作，想用說明書來做，那么中空玻璃手工刮膠怎么操作，從膠水的類型和結構來說明操作。
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.
要理解的是為什么要使用雙密封橡膠:
The first thing to understand is why double-sealant rubber is used:
1 .根據中空玻璃的質量要求，兩種密封劑主要有聚硫樹脂、聚氨酯和硅酮三大類，手動需要調整比例。
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樹脂和硅樹脂，而聚氨酯在我國起步較晚，很少使用。選擇適合你的膠水。
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.
手工刮膠的結構與組成
Structure and Composition of Hand Scraper
硅酮密封膠是指以聚硅氧烷為主要原料的一種密封膠，又稱硅酮密封膠。硅密封膠的聚合物鏈主要由硅—O—Si組成，在固化過程中交聯形成網狀硅—O—Si骨架結構。Si—O鍵能(444KJ/mol)非常高，遠遠高于其他聚合物鍵能，但也大于紫外線能(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硅酮密封膠分子結構使硅酮密封膠具有優異的耐高溫、耐低溫、耐氣候、耐紫外線老化、吸水率低;中空玻璃的缺點是透氣性高。
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.
手工刮膠容易出現的問題:
Hand scraper problems are easy to occur:
，比例不同
First, the proportions are different.
二世。不均勻部署
King II. Uneven deployment
三、不能使膠水立即在中空玻璃上混合后，讓它在玻璃上完成初硫化完成硫化的過程
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.
