(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.

Information
根據電池內部電解液的成分，配制相應的化學試劑，如鏗離子電池電解液模擬液(lmol/L LiPF。的碳酸乙烯醋(EC)和碳酸二甲醋(DMC)混合溶液，體積比為1:1)。將MS密封膠樣品浸泡在化學試劑中，在室溫下浸泡7天，觀察樣品的外觀變化，如是否出現溶脹、溶解、變色等現象，并測試其拉伸強度、硬度等性能變化，評佑其耐化學腐蝕性能。
電絕緣性能測試
電池MS密封膠的電絕緣性則使用絕緣電陰測試儀，按照GB/T 1410-2006標準進行測試。將MS密封膠樣品制成厚度為2 mm的薄片，在樣品表面涂上導電銀膠，然后將其安裝在絕緣電陰測試儀的測試電極上，施加500 V的直流電壓，測量樣品的絕緣電陰。同時，使用介電常數測試儀，按照GB/T 1693-2007['3〕標準，測量樣品的介電常數和介質損耗角正切值，評佑其電絕緣性能。
防震抗沖擊性能測試
利用振動試驗臺和沖擊試驗臺進行測試。振動試驗按照GB/T 2423.10-2019標準進行，將MS密封膠樣品固定在振動試驗臺上，設置振動頻率為10--100Hz，加速度為Sm/sz，振動時間為2h，觀察樣品是否出現脫落、開裂等現象。沖擊試驗按照GB/T2423.5-2019S標準進行，將樣品固定在沖擊試驗臺上，施加半正弦波沖擊，峰值加速度為50 g，脈沖持續時間為11 ms，沖擊次數為1000次，觀察樣品的損壞情況，評佑其防震抗沖擊性能。http://www.jifengjixie.cn/
