Tom qab tag nrho, cov tshuaj nplaum iav yog cov nplaum kho qhov kub hauv chav uas cuam tshuam loj heev los ntawm ib puag ncig. Cia peb saib seb kev siv cov kua nplaum iav hauv qhov chaw kub tsawg thaum lub caij ntuj no. 3 cov lus nug nquag nug!
1. Thaum siv cov tshuaj nplaum iav hauv qhov chaw kub tsawg, qhov teeb meem thawj zaug yog qeeb kho
Qhov kub thiab av noo ntawm ib puag ncig muaj qee yam cuam tshuam rau nws qhov ceev ntawm kev kho. Rau cov khoom siv silicone sealant ib-feem, qhov kub thiab av noo siab dua, qhov ceev ntawm kev kho sai dua. Thaum lub caij nplooj zeeg thiab lub caij ntuj no, qhov kub poob qis heev, uas txo qhov kev kho ntawm cov khoom siv silicone sealant, ua rau lub sijhawm qhuav ntawm qhov chaw qeeb dua thiab kev kho tob. Feem ntau, thaum qhov kub qis dua 15 ° C, qhov ceev ntawm kev kho yuav qeeb dua. Rau cov ntaub thaiv phab ntsa hlau, vim yog qhov kho qeeb ntawm cov khoom siv sealant thaum lub caij nplooj zeeg thiab lub caij ntuj no, thaum qhov sib txawv ntawm qhov kub ntawm hnub thiab hmo ntuj loj heev, qhov sib txawv ntawm cov phaj yuav ncab thiab nias heev, thiab cov khoom siv sealant ntawm cov pob qij txha yuav yooj yim bulge.
2. Cov iav sealant siv rau hauv qhov chaw kub tsawg, thiab qhov sib txuas ntawm cov kua nplaum iav thiab cov khoom siv yuav raug cuam tshuam
Thaum qhov kub thiab av noo txo qis, qhov kev sib txuas ntawm cov silicone sealant thiab lub substrate kuj yuav raug cuam tshuam. Feem ntau haum rau qhov chaw uas siv silicone sealant: ob-component yuav tsum tau siv rau hauv qhov chaw huv ntawm 10 ° C ~ 40 ° C thiab av noo txheeb ze 40% ~ 60%; ib-component yuav tsum tau siv ntawm 4 ° C ~ 50 ° C thiab av noo txheeb ze 40% ~ 60% siv rau hauv qhov chaw huv. Thaum qhov kub qis, qhov ceev kho thiab reactivity ntawm sealant txo qis, thiab qhov ntub ntawm sealant thiab qhov chaw ntawm lub substrate txo qis, ua rau lub sijhawm ntev dua rau sealant los tsim kev sib txuas zoo nrog lub substrate.
3. Cov khoom siv iav siv rau hauv qhov chaw kub tsawg, thiab cov kua nplaum iav tuab dua
Thaum qhov kub txo qis, cov silicone sealant yuav maj mam tuab thiab qhov extrudability yuav tsis zoo. Rau ob-component sealants, qhov tuab ntawm Cheebtsam A yuav ua rau lub siab ntawm lub tshuab kua nplaum nce, thiab cov kua nplaum tso tawm yuav txo qis, ua rau cov kua nplaum tsis txaus siab. Rau ib-component sealant, cov colloid yog thickened, thiab lub siab extrusion yog siab thaum lub sijhawm ntawm tes siv rab phom kua nplaum kom txo qhov ua haujlwm ntawm tes.
Yuav ua li cas los daws teeb meem
Yog tias koj xav tsim kho hauv qhov chaw kub tsawg, ua ntej ua qhov kev sim kua nplaum me me kom paub tseeb tias cov kua nplaum iav tuaj yeem kho tau, qhov nplaum zoo, thiab tsis muaj teeb meem tshwm sim ua ntej kev tsim kho.
