(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.

達產品中電纜矩形連接器大部分采用雙組份聚氨酯密封膠進行密封，操作步驟多，過程復雜，平均合格率不高，其返修難度大，周期長，直接影響著整部產品的質量和裝配周期，沿用傳統的配制及灌封技術已經不能滿足現有的產品裝配需求通過開展有針對性的改進活動，試驗尋找到攪拌膠液的最優參數組合，適用于今后其他多組份膠的配制過程，具有積極的推廣意義隨若達產任務的不斷擴展，嘗、裝產品中對電纜連接器的雙組份聚氨酯密封膠保護要求越來越多，再加幾產品服役的地域條件復雜、必候惡劣，因此電纜連按器密封質的好壞對一產,整體質的影響得越來越日前在我所產，均什過程中，泣、裝工藝都對電纜連接器提出瀟封膠保護氣的要求，尤其足人部分連接器需要采川雙組份聚氨酯密封膠進行密封，操作步驟多，過程復雜，廠前均合格率僅為，如果山幾不含格而造成返，拆除已經完全引化的雙組份聚氨酯密封膠難度，周期長，將直接影響整部)的計交臨叼期本文旨在操作流程和藝參數等方血.通過升一展有釗對性的改進活動，來實現提尚并穩;連接器雙組份聚氨酯密封膠合格率的的目前生產現狀對某)人線隊而的2411個矩形連接器進初灌封，介格19R個，介格率為具體漱封缺陷統計見表1、從現場調杏結果及缺叫以很直觀地石出，連按器寸缺階問題的癥結要是集中(“有孔”項到灌封缺陷總數犯次的833%，成為急需解決的關鍵性問題1.2氣孔定義又孔又稱氣泡，足液體混合過程，混入廠罕氣，一時不易消狀殘留在液體內部或表向f右我所典《防水川雙組份聚氨酯密封膠工藝》影響連接器雙組份聚氨酯密封膠灌封合格率的因素較多，我們對其進行了分析，從人、機、料、法和環等五個方面共查找原因，繪制了系統圖如圖1所示。通過上圖可以看出，共有十一個導致連接器雙組份聚氨酯密封膠灌封產生氣孔的末端因素，為了確定出主要原因，制定了要因確認計劃(見表2)，對11項末端因素分別進行調查和分析，逐一確認。通過以上逐條確認，經過進一步的分析論證，找到了導致連接器雙組份聚氨酯密封膠灌封產生氣泡的主要原因為:人工攪拌不勻速;自然脫泡速度慢。www.qiquanonline.com
