(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.

針對(duì)MS密封膠常溫拉伸強(qiáng)度,加速老化后的斷裂伸長(zhǎng)率、拉伸強(qiáng)度、60%定伸模量及最大強(qiáng)度伸長(zhǎng)率是影響模型預(yù)測(cè)的關(guān)鍵變量。其中,加速后斷裂伸長(zhǎng)率、拉伸強(qiáng)度均與預(yù)測(cè)強(qiáng)度呈正相關(guān),指標(biāo)越大,模型越傾向于高強(qiáng)度預(yù)測(cè);而加速60%模量與最大強(qiáng)度伸長(zhǎng)率則與預(yù)測(cè)強(qiáng)度呈負(fù)相關(guān),指標(biāo)越低,模型輸出的強(qiáng)度預(yù)測(cè)值越高。
針對(duì)MS密封膠常溫最大強(qiáng)度伸長(zhǎng)率,加速老化后的斷裂伸長(zhǎng)率、最大強(qiáng)度伸長(zhǎng)率、60%定伸模量及100%定伸模量對(duì)模型預(yù)測(cè)的影響最為突出。數(shù)據(jù)顯示,加速后斷裂伸長(zhǎng)率、最大強(qiáng)度伸長(zhǎng)率及60%定伸模量均與預(yù)測(cè)伸長(zhǎng)率呈正相關(guān),指標(biāo)越高,模型越傾向于高伸長(zhǎng)率預(yù)測(cè);與之相反,加速100%定伸模量與預(yù)測(cè)伸長(zhǎng)率呈負(fù)相關(guān),該指標(biāo)越高,模型輸出的伸長(zhǎng)率預(yù)測(cè)值越低。
機(jī)器學(xué)習(xí)模型的構(gòu)建高度依賴(lài)大規(guī)模數(shù)據(jù)驅(qū)動(dòng)�;赟HAP特征歸因分析可知,模型能夠依據(jù)兩類(lèi)MS密封膠的關(guān)鍵物理化學(xué)參數(shù)實(shí)現(xiàn)預(yù)測(cè)推理。具體而言,加速老化后的特征指標(biāo)表征了MS密封膠內(nèi)部交聯(lián)結(jié)構(gòu)的穩(wěn)定性,拉伸強(qiáng)度與模量則反映其分子鏈間的內(nèi)聚強(qiáng)度而斷裂伸長(zhǎng)率體現(xiàn)了交聯(lián)網(wǎng)絡(luò)的延展性及分子鏈的柔順性。
由圖還可知:針對(duì)低模量耐候MS密封膠,模型將加速老化后的低拉伸強(qiáng)度、高斷裂伸長(zhǎng)率及低模量特征相關(guān)聯(lián),實(shí)現(xiàn)了對(duì)常溫模量的精準(zhǔn)預(yù)測(cè);而對(duì)于MS密封膠等高強(qiáng)度MS密封膠,模型則將高拉伸強(qiáng)度與低斷裂伸長(zhǎng)率特征藕合,進(jìn)而輸出相應(yīng)的預(yù)測(cè)結(jié)果。
綜上,XGBoost模型經(jīng)對(duì)兩類(lèi)MS密封膠性能數(shù)據(jù)的深度學(xué)習(xí),有效識(shí)別了耐候膠的低模量特性及MS密封膠的高強(qiáng)度特征,證實(shí)其能夠通過(guò)解析MS密封膠內(nèi)部分子交聯(lián)網(wǎng)絡(luò)結(jié)構(gòu)及其延展性特征,實(shí)現(xiàn)對(duì)常溫力學(xué)性能的高精度預(yù)測(cè)。http://www.mychangxin.com/
