(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

“直接看”與“算一算”結果有差異，但其重要因素A, C和次要因素D是一致的，均為AC,DZo次要因素B要在B,B;中選取，由于考慮工作場地的環境溫度，24℃左右的溫度較容易達到，為此選B。經綜合評定，其最佳工藝組合可能是A尹ZGD,即:攪拌速度300 r/rain;丁基防水嵌縫密封膠膠液溫度24℃;攪拌時間1 min;丁基防水嵌縫密封膠膠液量480 g。

選擇兩位操作熟練度相似的操作者進行丁基防水嵌縫密封膠膠液攪拌試驗，分別進行10次，檢查工藝組合的效果.攪拌過程中產生的氣泡數遠低于5個，試驗取得成果。采用負壓除氣泡方式縮短脫泡時間。經過資料查找并借鑒同行業的經驗，決定選用一種抽真空的裝置，采用負壓除氣泡的方式可一以迅速地排除膠粘劑混合過程中因為化學反)w等原因產生的氣體，從而進一步化解連接器密封過程中丁基防水嵌縫密封膠膠液自然脫泡速度慢與丁基防水嵌縫密封膠膠液固化時間知之問的矛盾，有效提高連接器的灌封效率和質量采用SHD-3真空泵，按照典型工藝文件的要求以及對策實施一的操作方法配制五組樣件，將其依次放入密封罐內，參照行業標準以及設備說明設置真空氣壓值，實施負壓(0.09 MPa)脫泡8一10 min ,隨后將樣件取u,o,將丁基防水嵌縫密封膠膠液表面的氣泡去除，實施灌封。

五組樣件在經過1O h的完全固化后，在膠體內均未產生氣泡。試驗證明，采用施加負壓的方式，力速了丁基防水嵌縫密封膠膠液混合后的化學反應，使得丁基防水嵌縫密封膠膠液混合后產生的氣泡在丁基防水嵌縫密封膠膠液粘稠度增大之前排放出來，大大縮短了丁基防水嵌縫密封膠膠液脫泡時間，將固化過程中產生的氣泡數降為零，達到目標。工藝過程中的部分圖片如圖5一圖8所示。www.qiquanonline.com
