Silicone sealantyog cov khoom siv ntau yam siv dav hauv kev sib khi thiab daim ntawv thov kev sib txuas. Txawm li cas los xij, silicone sealants yuav tsis ua raws li qee qhov chaw thiab cov khoom siv. Kev nkag siab txog cov kev txwv no yog qhov tseem ceeb rau kev ua tiav kev sib khi thiab kev sib koom ua ke ntev ntev. Hauv qhov blog no, peb yuav tshawb txog cov yam tseem ceeb uas cuam tshuam rau silicone sealant adhesion thiab muab cov kev daws teeb meem rau kev kho silicone sealant uas tsis yog-stick nto.
Q:Dab tsi yog silicone sealant lo rau?
A: Silicone sealants yuav tsis ua raws li qee qhov chaw, suav nrog:
1. Cov ntaub ntawv tsis ntxeem tau: Silicone sealants tsis khi zoo rau cov khoom tsis ntxeem tau xws li iav, hlau, thiab yas. Lub zog qis ntawm cov chaw no ua rau nws nyuaj rau silicones los tsim cov ntawv cog lus muaj zog.
2. PTFE thiab lwm yam fluoropolymer-raws li cov ntaub ntawv: PTFE thiab lwm yam fluoropolymer-raws li cov ntaub ntawv paub txog lawv cov khoom tsis-stick, uas kuj ua rau lawv resistant rau silicone sticking.
3. Cov chaw tsis huv: Silicone sealant yuav tsis ua raws li cov khoom siv roj, roj lossis lwm yam khoom. Kev npaj kom zoo yog qhov tseem ceeb los xyuas kom meej adhesion zoo.
4. High-density polyethylene (HDPE) thiab polypropylene: Cov yas no muaj lub zog qis thiab nyuaj rau kev sib txuas nrog silicone sealants.
Q: Dab tsi yog qee qhov kev daws teeb meem rau kev kho qhov chaw uas silicone sealant yuav tsis lo?
A: Thaum silicone sealants yuav tsis ua raws li qee qhov chaw, muaj qee qhov kev daws teeb meem uas tuaj yeem txhim kho adhesion thiab ua kom muaj kev vam meej:
1. Kev Npaj Nto: Kev npaj kom zoo yog qhov tseem ceeb los txhawb kev ua kom adhesion. Qhov saum npoo yuav tsum huv, qhuav thiab tsis muaj cov kab mob xws li roj, roj lossis hmoov av. Siv cov kuab tshuaj uas tsim nyog lossis tshuaj ntxuav kom tshem tawm cov kab mob ua ntej siv silicone sealant.
2. Siv cov primer: Yog tias silicone sealant muaj teeb meem adhering rau ib qho chaw tshwj xeeb, siv primer tuaj yeem txhim kho adhesion. Primers yog tsim los txhim kho cov khoom sib txuas ntawm silicone sealants ntawm qhov nyuaj-rau-kev sib cog lus xws li yas thiab hlau.
3. Mechanical bonding: Rau qhov tsis muaj qhov ntxeem tau xws li iav thiab hlau, tsim kev sib txuas ntawm cov khoom siv kho tshuab tuaj yeem txhim kho adhesion. Qhov no tuaj yeem ua tiav los ntawm kev siv cov txheej txheem xws li xuab zeb lossis roughening saum npoo los muab kev tuav zoo dua rau silicone sealant.
4. Xaiv qhov zoo silicone sealant: Tsis yog txhua qhov silicone sealants haum rau txhua qhov chaw. Nws yog ib qho tseem ceeb uas yuav tau xaiv ib lub silicone sealant uas yog tsim tshwj xeeb rau hom nto koj ua haujlwm. Muaj cov khoom tshwj xeeb silicone sealants muaj rau kev sib txuas cov yas, hlau, thiab lwm yam nyuaj.
Thaum silicone sealant yog ntau yam thiab siv tau zoo thiab cov khoom sib khi, nws yog ib qho tseem ceeb kom paub txog nws cov kev txwv hauv kev sib txuas rau qee qhov chaw. Los ntawm kev nkag siab txog cov kev txwv no thiab siv cov kev daws teeb meem tsim nyog, nws muaj peev xwm ua tiav cov ntawv cog lus ruaj khov thiab kav ntev siv silicone sealants, txawm nyob rau ntawm qhov nyuaj. Kev npaj saum npoo kom zoo, siv cov primer, thiab xaiv cov silicone sealant kom raug yog qhov tseem ceeb hauv kev kov yeej kev sib tw sib tw thiab ua kom muaj kev sib khi zoo thiab daim ntawv thov kev sib txuas.
