我國(guó)玻璃加工行業(yè)的發(fā)展現(xiàn)狀與方向?
玻璃表面處理。玻璃表面處理包括兩個(gè)方面:一方面,豐富玻璃表面,即采用物理或化學(xué)方法在玻璃表面上制作不同的圖案和圖案;另一方面,涂覆玻璃表面。拋光玻璃:在生產(chǎn)浮法玻璃之前,需要對(duì)一些玻璃進(jìn)行拋光,以達(dá)到完全平行兩個(gè)表面的目的。拋光玻璃是用普通平板玻璃或壓延玻璃的兩個(gè)表面用碳化硅和硅砂等研磨劑拋光,然后用紅色粉末,鞣錫和氈拋光。 1958年,中國(guó)自行設(shè)計(jì)制造的往復(fù)式砂光機(jī)在上海耀華玻璃廠建成,以滿(mǎn)足鋼化和夾層玻璃對(duì)玻璃表面光滑度的要求。 1970年,洛陽(yáng)玻璃廠推出了德國(guó)單面連續(xù)拋光裝置及其軋制生產(chǎn)線。浮法玻璃的誕生取代了拋光玻璃。

Development of laminated glass film and film glass film. Since its introduction in the 1930s, PVB membranes have been an excellent intermediate material for automotive and aircraft windshields. PVB diaphragm has special properties: it has good adhesion to inorganic glass, the optical index of the diaphragm is very good, the light transmittance is over 90%; its heat resistance, cold resistance, impact resistance and resistance The aging performance is very good; its refractive index is almost the same as that of glass. So far, no other material has been able to replace it. However, since the production process of laminated glass using PVB diaphragm requires an autoclave and the production process is complicated, in 1997, Sekisui Chemical Co. Ltd. Japan, exhibited the non-autoclave laminated glass samples produced by them in China, namely the EN film interlayer. glass. This laminated glass is mainly used for building and decorative laminated glass.xx
中空玻璃在兩塊或多塊玻璃的周?chē)筛綦x框分開(kāi),然后用密封帶密封,使用的玻璃是平板夾層、鋼化、吸熱、熱反射、壓花等玻璃;為了滿(mǎn)足中空玻璃的性能要求,密封帶是用雙組分密封膠;間隔框是鋁框、不銹鋼框等。
那么該如何選擇呢?
夾膠玻璃和中空玻璃在某種程度上都有隔音隔熱的效果。不過(guò),夾膠玻璃具有非常好的抗震能力和防爆性能,中空玻璃具有更好的隔溫保熱性。
各種玻璃架系統(tǒng)的結(jié)構(gòu)特點(diǎn)、應(yīng)用范圍及選型原則
1.擱板式玻璃架。擱板式玻璃架通常均為人工存取玻璃方式,組裝式結(jié)構(gòu),層間距均勻可調(diào),玻璃物也常為散件或不是很重的已包裝物品(便于人工存取),玻璃架高度通常在2.5m以下,否則人工難以觸及(如輔以登高車(chē)則可設(shè)置在3m左右)。單元玻璃架跨度(即長(zhǎng)度)不宜過(guò)長(zhǎng),單元玻璃架深度(即寬度)不宜過(guò)深,按其單元玻璃架每層的載重量可分為輕、中、重型擱板式玻璃架,層板主要為鋼層板、木層板兩種。
