1.耐介質性能
空(kong)氣(qi)、水(shui)、油(you)、酸(suan)等統稱個質(zhi)，上海(hai)絕大多數膠粘(zhan)(zhan)劑抗空(kong)氣(qi)介(jie)(jie)質(zhi)性能好，被粘(zhan)(zhan)接(jie)件(jian)在空(kong)氣(qi)中(zhong)的(de)粘(zhan)(zhan)接(jie)強度高。而在不同(tong)性質(zhi)氣(qi)體或注(zhu)解體介(jie)(jie)質(zhi)中(zhong)的(de)粘(zhan)(zhan)接(jie)力則差(cha)別較大，甚至和工作過程(cheng)中(zhong)接(jie)角(jiao)的(de)個質(zhi)主(zhu)要是空(kong)氣(qi)、水(shui)、油(you)和酸(suan) 等。使用膠粘(zhan)(zhan)劑時，應選擇耐使用介(jie)(jie)質(zhi)的(de)膠。
2.粘接(jie)強(qiang)度:鵝頸管(guan)，金屬(shu)軟管(guan)，臺燈軟管(guan)
每1cm2的粘(zhan)合面，在常溫(wen)和(he)空氣介質中的破壞力稱為粘(zhan)接強(qiang)(qiang)度(du)(du)，以MPa表示。粘(zhan)接強(qiang)(qiang)度(du)(du)又分拉(la)伸強(qiang)(qiang)度(du)(du)、剪(jian)切強(qiang)(qiang)度(du)(du)，扭轉剪(jian)切強(qiang)(qiang)度(du)(du)和(he)剝離強(qiang)(qiang)長(chang)度(du)(du)，私人偵探(tan)分別指粘(zhan)接件在不同(tong)受力方向的破壞強(qiang)(qiang)度(du)(du)。選(xuan)擇膠粘(zhan)劑(ji)，應(ying)根據(ju)機(ji)械零(ling)件 的位置和(he)受力情(qing)誤解選(xuan)擇與之(zhi)相(xiang)適應(ying)的強(qiang)(qiang)度(du)(du)膠。
3.耐溫性能
指完(wan)全(quan)固化后的膠(jiao)(jiao)層可(ke)承受的溫度(du)范圍(wei)(wei)，如某(mou)種(zhong)(zhong)耐溫-60oC—120oC，即該(gai)粘(zhan)(zhan)及(ji)可(ke)在(zai)-60oC至120oC范圍(wei)(wei)內(nei)適(shi)用，超過此限(xian)，粘(zhan)(zhan)接力明顯(xian)下降。工(gong)程機械(xie)中(zhong)的風冷發動機，機體溫度(du)可(ke)達130oC。液壓(ya)油溫可(ke)達120oC，上海私(si)家偵探 選擇粘(zhan)(zhan)接膠(jiao)(jiao)時(shi)須在(zai)該(gai)種(zhong)(zhong)膠(jiao)(jiao)粘(zhan)(zhan)劑所能承受的溫度(du)范圍(wei)(wei)內(nei)。
4.固化時間
固(gu)(gu)化(hua)時(shi)(shi)間(jian)(jian)(jian)(jian)是(shi)指粘接(jie)時(shi)(shi)膠(jiao)(jiao)粘劑在常溫(wen)下(xia)同膠(jiao)(jiao)狀轉變成固(gu)(gu)體膠(jiao)(jiao)屋(wu)報所需(xu)的(de)(de)時(shi)(shi)間(jian)(jian)(jian)(jian)。固(gu)(gu)化(hua)時(shi)(shi)間(jian)(jian)(jian)(jian)可分(fen)為初(chu)固(gu)(gu)（或稱固(gu)(gu)定）時(shi)(shi)間(jian)(jian)(jian)(jian)和(he)全固(gu)(gu)時(shi)(shi)間(jian)(jian)(jian)(jian)。初(chu)固(gu)(gu)是(shi)指膠(jiao)(jiao)層承受粘接(jie)件不因自重而(er)脫落所需(xu)時(shi)(shi)間(jian)(jian)(jian)(jian)；全固(gu)(gu)是(shi)指膠(jiao)(jiao)層完全固(gu)(gu)化(hua)，并達到高粘霎強度和(he)耐介質性能所需(xu)時(shi)(shi)間(jian)(jian)(jian)(jian)。膠(jiao)(jiao)粘劑按初(chu)固(gu)(gu)時(shi)(shi)間(jian)(jian)(jian)(jian)可分(fen)為瞬干(gan)膠(jiao)(jiao)（或快干(gan)膠(jiao)(jiao)）和(he)慢(man)干(gan)膠(jiao)(jiao)兩(liang)種(zhong)(zhong)。瞬干(gan)膠(jiao)(jiao)的(de)(de)初(chu)固(gu)(gu)時(shi)(shi)間(jian)(jian)(jian)(jian)只(zhi)有幾(ji)秒或數十(shi)秒。磁(ci)力(li)泵對(dui)慢(man)干(gan)膠(jiao)(jiao)若(ruo)需(xu)縮短固(gu)(gu)化(hua)時(shi)(shi)間(jian)(jian)(jian)(jian)，可用(yong)熱力(li)吹(chui)、烘(hong)箱烘(hong)烤(kao)等(deng)措施加溫(wen)，但加熱溫(wen)度和(he)時(shi)(shi)間(jian)(jian)(jian)(jian) 應(ying)按不同膠(jiao)(jiao)種(zhong)(zhong)而(er)定。選擇瞬干(gan)或慢(man)干(gan)膠(jiao)(jiao)種(zhong)(zhong)，插板閥(fa)按粘接(jie)件的(de)(de)不同情況和(he)工作需(xu)要而(er)定。一般(ban)來(lai)說，慢(man)干(gan)膠(jiao)(jiao)的(de)(de)粘接(jie)強度和(he)抗介質性能優于瞬干(gan)膠(jiao)(jiao)。
