(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.

制定對策

要因確認以后，通過對問題進行分析，對癥下藥，并制定了相應的對策，見表3。

對策實施措

采用設備或工具、工裝進行硅烷改性聚氨酯密封膠膠液攪拌。

設計制作一種專用攪拌工裝，用其裝夾在手電鉆端部，通過調節手電鉆的轉速達到勻速攪拌的效果。從而彌補人工攪拌不能持續勻速的缺陷，減輕員工作業強度，有利于減少硅烷改性聚氨酯密封膠膠液攪拌過程中帶入較多空氣。攪拌工裝如圖2所示，攪拌方式如圖3所示C。

在攪拌過程中，發現有4個因素需要確定最佳條件，可采用正交試驗，得出最佳的工藝條件。

試驗目標:將攪拌過程中產生的氣泡數降低到5個以一下。

考核指標:氣泡數。

試驗因素:在硅烷改性聚氨酯密封膠膠液混合后攪拌過程中，經過研究，有4個因素需要確定最佳條件:A攪拌速度;13攪拌時間;C硅烷改性聚氨酯密封膠膠液溫度;D硅烷改性聚氨酯密封膠膠液量。

選用正交表:選用L9(34)正交表。共做9次試驗，生產上是可以接受的。

因素位級表見表4。

各因素對結果影響的重要程度。極差尺最大者，就是對結果影響程度最大，R最小則影響程度最小。因此，因素重要程度的次序為:A--C-D-B(2)直接看。第6號試驗最好，結果:氣泡數為1，其工藝條件為A, B C, D。(3)算一算二從位級之和(越小越好)可以看出，最好的工藝條件應是A B; C, D,(4)作趨勢分析。趨勢分析圖如圖4所示。

從趨勢圖上看，A因素和C因素還有潛力可挖。如果再提高A因素攪拌速度，會使產生氣泡的幾率增加;C因素攪拌時間如果再少些，硅烷改性聚氨酯密封膠A、B組份將得不到充分混合，影響灌膠質量，不可以減少時間。www.qiquanonline.com
