Thaum qhov kub thiab txias thiab cov nag txuas ntxiv, nws yuav tsis tsuas yog muaj qee yam cuam tshuam rau kev tsim khoom ntawm peb lub Hoobkas, tab sis ntau tus neeg siv khoom kuj tseem txhawj xeeb txog kev khaws cov sealants.
Silicone sealant yog chav kub vulcanized silicone roj hmab.Nws yog ib qho muab tshuaj txhuam ua los ntawm 107 silicone roj hmab thiab muab tub lim ua cov khoom siv tseem ceeb, ntxiv los ntawm tus neeg sawv cev crosslinking, tus neeg sawv cev thixotropic, tus neeg sawv cev sib txuas, thiab cov catalyst hauv lub tshuab nqus tsev.Nws reacts nrog dej hauv huab cua thiab solidifies tsim elastic silicone roj hmab.
Silicone sealant cov khoom muaj cov kev cai nruj ntawm qhov chaw cia khoom.Qhov chaw cia khoom tsis zoo yuav txo qis kev ua haujlwm ntawm silicone sealant, lossis txawm tias ua kom tawv.Hauv qhov xwm txheej hnyav, kev ua haujlwm ntawm qee yam ntawm silicone sealants yuav ploj, thiab cov khoom yuav raug muab pov tseg.
Cia peb tham txog qee cov lus qhia silicone sealants cia.
Nyob rau hauv qhov kub thiab txias ib puag ncig, silicone sealant yuav ua rau kom muaj kev laus, tsim "txo" tshwm sim, ua kom poob ntawm qee yam khoom, thiab ua rau lub neej luv.Yog li, qhov ntsuas kub cia muaj qhov cuam tshuam zoo rau qhov zoo ntawm silicone sealant, thiab qhov ntsuas kub yuav tsum tsis pub tshaj 27 ° C (80.6 ° F).
Nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, qhov kub thiab txias tsis dhau yuav ua rau tus neeg sawv cev sib txuas thiab tus neeg sawv cev sib txuas hauv cov kua nplaum silicone kom crystallize.Cov muaju yuav ua rau cov kua nplaum tsis zoo thiab cov khoom siv hauv zos tsis sib xws.Thaum sizing, colloid tuaj yeem kho hauv zos tab sis tsis kho hauv zos.Yog li ntawd, crystallized silicone sealant tsis tuaj yeem siv.Txhawm rau tiv thaiv cov roj hmab silicone los ntawm crystallizing, qhov chaw cia yuav tsum tsis txhob qis dua -5 ° C (23 ℉).
Nyob rau hauv ib puag ncig high-humidity, silicone sealant solidifies thaum nws ntsib dej vapor.Qhov ntau dua qhov txheeb ze cov av noo nyob rau hauv qhov chaw cia, qhov ceev ntawm silicone sealant kho.Muaj silicone sealants tsim ib tug loj npaum li cas ntawm qhuav sealant 3-5 lub hlis tom qab ntau lawm, uas yog ncaj qha ntsig txog cov av noo ntawm qhov chaw cia siab heev. , thiab nws yog qhov tsim nyog yuav tsum tau cov av noo ntawm qhov chaw cia yog ≤70%.
Txhua yam, cov khoom siv roj hmab silicone yuav tsum muab cia rau hauv qhov chaw qhuav, qhov cua, thiab qhov chaw txias.Qhov zoo tshaj plaws cia kub yog nyob nruab nrab ntawm -5 thiab 27 ° C (23--80.6℉), thiab qhov zoo tshaj plaws cia av noo yog ≤70%.Nws tsis txhob khaws cia rau hauv qhov chaw raug cua, nag, thiab tshav ntuj ncaj qha.Raws li kev thauj mus los ib txwm thiab khaws cia, lub sijhawm cia yog tsawg kawg 6 lub hlis txij li hnub tsim khoom.
Txhawm rau tiv thaiv qhov tsis zoo ntawm cov khoom siv roj hmab silicone thaum lub sijhawm khaws cia, lub tsev khaws khoom yuav tsum nyob hauv qhov chaw txias yam tsis muaj hnub ci ncaj qha.Nws tseem tsis tuaj yeem xaiv qhov chaw qis qis uas ua rau cov dej tsub zuj zuj.Rau warehouses nrog kub siab, peb yuav tsum tau ua ib tug zoo txoj hauj lwm ntawm txias lub ru tsev.Lub tsev khaws khoom nrog cov txheej txheem cua sov ntawm lub ru tsev yog qhov zoo tshaj plaws, thiab yuav tsum tau ua kom cua nyob rau tib lub sijhawm.Yog tias muaj kev tso cai, lub tsev khaws khoom tau nruab nrog cua txias thiab dehumidifiers kom lub tsev khaws khoom ntawm qhov kub thiab txias tsis tu ncua thaum lub caij ntuj sov thiab lub caij ntuj nag.
