Thaum qhov kub thiab txias siab thiab los nag tseem txuas ntxiv mus, nws yuav tsis tsuas yog muaj qee qhov cuam tshuam rau kev tsim khoom ntawm peb lub Hoobkas xwb, tab sis ntau tus neeg siv khoom kuj txhawj xeeb heev txog kev khaws cia cov sealants.
Cov roj hmab silicone sealant yog cov roj hmab silicone vulcanized kub hauv chav. Nws yog ib qho nplaum ua los ntawm 107 silicone roj hmab thiab filler ua cov khoom siv tseem ceeb, ntxiv los ntawm crosslinking agent, thixotropic agent, coupling agent, thiab catalyst hauv lub xeev nqus tsev. Nws reacts nrog dej hauv huab cua thiab khov ua cov roj hmab silicone elastic.
Cov khoom siv silicone sealant muaj cov kev cai nruj heev rau qhov chaw cia khoom. Qhov chaw cia khoom tsis zoo yuav ua rau cov silicone sealant ua haujlwm tsis zoo, lossis ua rau nws tawv. Hauv cov xwm txheej hnyav, qhov ua tau zoo ntawm qee yam ntawm cov silicone sealant yuav ploj mus, thiab cov khoom yuav raug pov tseg.
Cia peb tham txog qee cov lus qhia khaws cia cov khoom siv silicone sealants.
Nyob rau hauv ib puag ncig kub siab, silicone sealant yuav ua rau kom cov laus sai dua, ua rau muaj "kev txo qis", ua rau qee yam khoom poob sai dua, thiab ua rau lub txee luv dua. Yog li ntawd, qhov kub thiab txias ntawm kev khaws cia muaj feem cuam tshuam loj rau qhov zoo ntawm silicone sealant, thiab qhov kub thiab txias ntawm kev khaws cia yuav tsum tsis pub tshaj 27 ° C (80.6 ° F).
Nyob rau hauv ib puag ncig kub qis, qhov kub thiab txias qis 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 crystals yuav ua rau cov kua nplaum tsis zoo thiab cov khoom ntxiv hauv zos tsis sib xws. Thaum ntsuas qhov loj, cov colloid tuaj yeem kho tau hauv zos tab sis tsis kho hauv zos. Yog li ntawd, cov sealant silicone crystallized tsis tuaj yeem siv. Txhawm rau tiv thaiv cov roj hmab silicone los ntawm crystallizing, qhov chaw cia khoom yuav tsum tsis txhob qis dua -5 ° C (23 ℉).
Nyob rau hauv ib puag ncig uas muaj av noo ntau, cov roj hmab silicone sealant yuav khov thaum nws ntsib cov dej pa. Qhov av noo ntau dua nyob rau hauv qhov chaw khaws cia, cov roj hmab silicone sealant yuav kho sai dua. Ntau cov roj hmab silicone sealant tsim cov roj hmab qhuav ntau 3-5 lub hlis tom qab tsim tawm, uas yog ncaj qha cuam tshuam nrog qhov av noo ntawm qhov chaw khaws cia siab dhau, thiab nws yog qhov tsim nyog dua kom xav tau qhov av noo ntawm qhov chaw khaws cia kom yog ≤70%.
Tag nrho hauv txhua qhov, cov khoom siv roj hmab silicone yuav tsum tau khaws cia rau hauv qhov chaw qhuav, cua nkag, thiab txias. Qhov kub zoo tshaj plaws rau kev khaws cia yog ntawm -5 thiab 27 ° C (23--80.6 ℉), thiab qhov av noo zoo tshaj plaws rau kev khaws cia yog ≤70%. Nws zam kev khaws cia rau hauv qhov chaw uas raug cua, nag, thiab tshav ntuj ncaj qha. Raws li kev thauj mus los thiab kev khaws cia ib txwm muaj, lub sijhawm khaws cia yog tsawg kawg 6 lub hlis txij li hnub tsim khoom.
Yuav kom tiv thaiv kom tsis txhob muaj qhov tsis zoo ntawm cov khoom siv roj hmab silicone thaum lub sijhawm khaws cia, lub tsev rau khoom yuav tsum nyob rau hauv qhov chaw txias uas tsis muaj tshav ntuj ncaj qha. Nws kuj tsis tuaj yeem xaiv cov chaw qis uas yooj yim rau kev sib sau ua ke dej. Rau cov tsev rau khoom uas muaj qhov kub siab, peb yuav tsum ua haujlwm zoo ntawm kev txias lub ru tsev. Lub tsev rau khoom nrog txheej rwb thaiv tsev kub ntawm lub ru tsev yog qhov zoo tshaj plaws, thiab yuav tsum tau ua pa tib lub sijhawm. Yog tias muaj xwm txheej tso cai, lub tsev rau khoom muaj cov cua txias thiab cov dehumidifiers kom lub tsev rau khoom nyob rau ntawm qhov kub thiab txias tas li thaum lub caij ntuj sov thiab lub caij los nag.
