Vim tias qhov kub tsis tshua muaj nyob rau lub caij ntuj no, koj yuav ntsib teeb meem dab tsi thaum siv iav sealant nyob rau hauv ib puag ncig kub? Tom qab tag nrho, iav sealant yog chav tsev kub kho cov nplaum uas cuam tshuam rau ib puag ncig. Cia peb saib ntawm kev siv cov iav kua nplaum nyob rau lub caij ntuj no uas tsis muaj qhov kub thiab txias. 3 lus nug!
1. Thaum iav sealant siv nyob rau hauv ib puag ncig uas tsis muaj kub, thawj qhov teeb meem yog qeeb kho
Qhov kub thiab av noo ntawm ib puag ncig muaj qee yam cuam tshuam rau nws qhov nrawm nrawm. Rau ib qho khoom siv silicone sealants, qhov kub thiab av noo ntau dua, qhov kev kho ceev nrawm dua. Nyob rau lub caij nplooj zeeg thiab lub caij ntuj no, qhov kub thiab txias poob qis, uas txo qhov kev kho cov tshuaj tiv thaiv ntawm silicone sealant, ua rau lub sij hawm qeeb qeeb ziab thiab sib sib zog nqus curing. Feem ntau, thaum qhov kub qis dua 15 ° C, qhov kev kho ceev yuav qeeb qeeb. Rau cov hlau vaj huam sib luag kab hlau rhuav phab ntsa, vim qhov kev kho qeeb ntawm cov sealant nyob rau lub caij nplooj zeeg thiab lub caij ntuj no, thaum qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj yog qhov loj, qhov sib txawv ntawm cov phiajcim yuav nthuav dav heev thiab compressed, thiab sealant ntawm cov pob qij txha yuav yooj yim pob.
2. Iav sealant yog siv nyob rau hauv qhov kub thiab txias ib puag ncig, thiab cov nyhuv bonding ntawm iav kua nplaum thiab substrate yuav raug cuam tshuam.
Raws li qhov kub thiab av noo txo, qhov adhesion ntawm silicone sealant thiab substrate kuj yuav cuam tshuam. Feem ntau haum rau ib puag ncig uas siv silicone sealant: ob lub ntsiab lus yuav tsum tau siv nyob rau hauv qhov chaw huv si ntawm 10 ° C ~ 40 ° C thiab cov av noo ntawm 40% ~ 60%; ib leeg-khoom yuav tsum tau siv ntawm 4 ° C ~ 50 ° C thiab txheeb ze av noo 40% ~ 60% siv nyob rau hauv huv si ambient tej yam kev mob. Thaum qhov kub thiab txias, qhov curing npaum li cas thiab reactivity ntawm lub sealant txo, thiab lub wettability ntawm lub sealant thiab nto ntawm substrate yuav txo, ua rau lub sij hawm ntev rau lub sealant los tsim ib tug zoo daim ntawv cog lus nrog lub substrate.
3. Iav sealant yog siv nyob rau hauv qhov kub thiab txias ib puag ncig, thiab iav kua nplaum yog thickened
Raws li qhov kub thiab txias, silicone sealant yuav maj mam thicken thiab extrudability yuav ua tsis zoo. Rau ob lub ntsiab sealants, thickening ntawm tivthaiv A yuav ua rau lub siab ntawm lub tshuab kua nplaum yuav nce, thiab cov kua nplaum tawm yuav txo, uas ua rau cov kua nplaum tsis zoo. Rau ib qho khoom siv sealant, lub colloid yog thickened, thiab lub extrusion siab kuj siab heev thaum lub sij hawm tus txheej txheem ntawm manually siv ib tug kua nplaum phom los txo cov efficiency ntawm phau ntawv ua hauj lwm.
Yuav daws li cas
Yog tias koj xav tsim kho nyob rau hauv qhov chaw qis qis, ua ntej ua qhov chaw me me ntawm cov kua nplaum kom paub meej tias cov iav kua nplaum tuaj yeem kho tau, qhov adhesion zoo, thiab tsis muaj teeb meem tshwm sim ua ntej kev tsim kho.Yog tias muaj kev tso cai, thawj zaug nce. qhov kub ntawm qhov kev tsim kho ib puag ncig ua ntej kev tsim kho
