1. Kev kho qeeb
Thawj qhov teeb meem uas tam sim ntawd poob rau hauv ambient kub coj mus rau lubsilicone structural sealantyog tias nws zoo nkaus li kho thaum lub sij hawm daim ntawv thov, thiab cov qauv silicone yog ntom.
Cov txheej txheem kho ntawm silicone sealant yog cov txheej txheem tshuaj tiv thaiv, thiab qhov kub thiab av noo ntawm ib puag ncig muaj qee yam cuam tshuam rau nws qhov kev kho ceev.Rau ib qhosilicone structural sealants, qhov siab dua qhov kub thiab av noo, qhov nrawm nrawm yuav yog.Tom qab lub caij ntuj no, qhov kub thiab txias poob qis, thiab tib lub sijhawm, nrog cov av noo tsawg, kev kho cov tshuaj tiv thaiv ntawm cov txheej txheem sealant raug cuam tshuam, yog li kev kho ntawm cov txheej txheem sealant qeeb.Raws li ib txwm muaj, thaum qhov kub thiab txias qis dua 15 ℃, qhov tshwm sim ntawm kev kho qeeb ntawm cov txheej txheem sealant yog pom tseeb dua.
Kev daws: Yog tias tus neeg siv xav tsim kho nyob rau hauv qhov chaw tsis muaj qhov kub thiab txias, nws raug nquahu kom ua qhov chaw me me ntawm silicone sealant kuaj ua ntej siv, thiab ua cov tev adhesion kuaj kom paub meej tias cov txheej txheem sealant tuaj yeem kho tau, qhov adhesion zoo, thiab qhov tsos tsis muaj teeb meem.thaj chaw siv.Txawm li cas los xij, thaum lub ambient kub qis li 4 ° C, kev tsim kho cov txheej txheem sealant tsis pom zoo.
Lub sealant yog glued siv qhov kub thiab av noo ntawm ib puag ncig.
2. Cov teeb meem kev sib khi
Nrog rau qhov txo qis ntawm qhov kub thiab av noo thiab kev kho qeeb, kuj tseem muaj qhov teeb meem ntawm kev sib txuas ntawm cov txheej txheem sealant thiab substrate.Cov kev cai dav dav rau kev sivsilicone structural sealantCov khoom lag luam yog: qhov chaw huv si nrog qhov kub ntawm 10 ° C txog 40 ° C thiab cov av noo ntawm 40% mus rau 80%.Tshaj li qhov ntsuas kub tsawg kawg nkaus saum toj no, kev sib txuas ceev yog qeeb, thiab lub sij hawm ua kom tag nrho cov ntawv cog lus rau lub substrate yog ntev.Nyob rau tib lub sijhawm, thaum qhov kub thiab txias qis dhau lawm, qhov ntub dej ntawm cov nplaum thiab qhov chaw ntawm lub substrate yuav txo qis, thiab tej zaum yuav muaj huab cua tsis txaus ntseeg los yog te rau ntawm qhov chaw ntawm lub substrate, uas cuam tshuam rau qhov adhesion ntawm cov txheej txheem sealant thiab cov khoom siv. substrate.
Kev daws: Thaum qhov tsawg kawg nkaus kev tsim kho kub ntawm cov txheej txheem sealant yog 10 ° C, cov txheej txheem sealant yog sib txuas rau lub substrate nyob rau hauv qhov tseeb.Kev kuaj adhesion yuav tsum tau ua nyob rau hauv qhov kub thiab txias qhov chaw tsim kho kom paub meej tias adhesion zoo ua ntej kev tsim kho.Lub Hoobkas kev txhaj tshuaj ntawm cov qauv txheej txheem sealant tuaj yeem ua kom qhov kev kho ntawm cov txheej txheem sealant los ntawm kev ua kom kub thiab av noo ntawm ib puag ncig uas siv cov txheej txheem sealant, thiab tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau ua kom ntev lub sijhawm kho kom zoo.
3. Ua kom viscosity
Cov qauv sealantsyuav maj mam thicken thiab ua kua dej tsawg dua li qhov kub thiab txias.Rau ob lub ntsiab lus sealants, structural sealants nce viscosity yuav ua rau kom lub siab ntawm lub tshuab kua nplaum thiab txo cov extrusion ntawm cov qauv sealant.Rau ib qho khoom siv sealants, cov txheej txheem sealant thickens, nce siab ntawm rab phom kua nplaum kom extrude tus qauv sealant tuaj yeem siv sijhawm ntev thiab ua haujlwm hnyav rau kev tuav haujlwm.
Kev daws: Yog tias tsis muaj kev cuam tshuam rau kev tsim kho kev ua haujlwm, qhov kub tsis tshua muaj tuab yog qhov tshwm sim ib txwm muaj, thiab tsis tas yuav tsum ntsuas kev txhim kho.
Yog tias qhov kev tsim kho muaj txiaj ntsig, nws tuaj yeem xav txog kev ua haujlwm kub ntawm cov txheej txheem sealant los yog siv qee qhov kev ntsuas cua sov, xws li khaws cia cov txheej txheem sealant hauv chav cua sov lossis chav cua txias ua ntej, txhim kho lub rhaub rau cua sov hauv. lub gluing rhiav, thiab nce lub
