Hauv cov qhov rooj thiab qhov rai, cov tshuaj sealant feem ntau yog siv rau kev sib koom ua ke ntawm cov thav duab qhov rai thiab iav, thiab kev sib koom ua ke ntawm cov thav duab qhov rai thiab phab ntsa sab hauv thiab sab nraud. Teeb meem hauv kev siv cov tshuaj sealant rau qhov rooj thiab qhov rai yuav ua rau cov foob qhov rooj thiab qhov rai tsis ua haujlwm, ua rau dej xau, cua xau thiab lwm yam teeb meem, uas yuav cuam tshuam loj heev rau qhov zoo ntawm cov qhov rooj thiab qhov rai. Qhia txog qee qhov teeb meem uas tshwm sim hauv kev siv cov tshuaj sealant rau qhov rooj thiab qhov rai, thiab muab cov kev daws teeb meem los ntawm kev tshuaj xyuas cov laj thawj los pab cov neeg siv siv cov tshuaj sealant zoo. Ua ntej tshaj plaws, kuv yuav qhia txog cov teeb meem feem ntau: kev tsis sib haum xeeb, kev sib txuas tsis zoo, thiab teeb meem khaws cia.
① Tsis Sib Haum
Qee cov khoom siv ntxiv uas siv rau hauv qhov rooj thiab qhov rai sib dhos, xws li cov khoom siv roj hmab (cov ntaub roj hmab, cov ntaub roj hmab, thiab lwm yam), feem ntau muaj kev sib cuag ze nrog cov sealant. Txawm li cas los xij, qee cov khoom roj hmab yuav ntxiv roj hmab lossis lwm yam khoom me me uas tsis sib haum nrog lub kaw lus sealant vim yog tus tsim khoom txo tus nqi lossis lwm yam kev xav. Thaum cov khoom roj hmab no sib cuag nrog cov sealant silicone, roj roj hmab lossis lwm yam khoom me me yuav txav mus rau cov sealant, thiab txawm tias txav mus rau qhov chaw ntawm cov sealant. Thaum siv, nyob rau hauv kev ua ntawm lub hnub ci thiab ultraviolet rays, cov sealant yuav dhau los ua daj. Qhov xwm txheej no pom tseeb dua ntawm cov nplaum qhov rooj thiab qhov rai nrog cov xim sib dua.
Yog li ntawd, peb xav kom ua ntejcov tshuaj nplaumYog siv, qhov kev sim sib xws ntawm cov sealant thiab cov ntaub ntawv uas nws kov yuav tsum tau ua raws li txoj kev sim sib xws hauv Appendix A ntawm GB 16776 los txiav txim siab qhov sib xws ntawm cov sealant thiab cov substrate, thiab raws li txoj kev sim sib xws. Kev tsim kho tau ua raws li qhov xav tau los ntawm cov txiaj ntsig ntawm kev sim.
② Kev sib txuas tsis zoo
Hauv daim ntawv thov ntawm qhov rooj thiab qhov raisilicone sealant,Cov khoom siv uas yuav sib chwv tau yog iav, txhuas, cement mortar, vuas ceramic, xim phab ntsa, thiab lwm yam. Tej zaum yuav muaj roj, hmoov av lossis lwm yam khoom seem ntawm qhov chaw ntawm cov ntaub ntawv no. Yog tias qhov kev sib txuas tsis tau lees paub ua ntej kev tsim kho, nws yuav ua rau qhov kev sib txuas tsis zoo ntawm lub qhov rooj thiab qhov rai silicone sealant. Thaum siv cov silicone sealant ntawm qhov sib koom ua ke ntawm qhov rooj thiab qhov rai thiab phab ntsa sab nraud ntawm cement mortar, yog tias cov hmoov av thiab xuab zeb ntawm qhov chaw ntawm cement mortar ntawm phab ntsa sab nraud tsis tau ntxuav, tej zaum yuav muaj qhov tshwm sim ntawm kev tsis sib txuas tom qab cov sealant kho.
Yog li ntawd, thaum siv cov silicone sealant tiag tiag, yuav tsum tau them sai sai rau qhov kev kho ua ntej ntawm qhov chaw ntawm cov khoom siv uas yuav tsum tau lo rau, thiab siv cov txheej txheem tsim nyog los tshem tawm cov roj, hmoov av, xuab zeb, thiab cov txheej xoob uas yooj yim poob.
③ Teeb meem khaws cov sealant
Cov khoom siv foobcov khoom lag luam yog cov khoom siv tshuaj lom neeg thiab muaj lub sijhawm khaws cia, yog li lawv yuav tsum tau siv rau hauv lub sijhawm khaws cia. Yog tias cov sealant tau dhau nws lub sijhawm khaws cia, nws yuav ua rau qhov kev kho kom zoo qeeb dua, kho tsis zoo lossis tsis kho.
Raws li cov kev cai ntawm cov xwm txheej khaws cia hauv cov qauv ntawm cov sealant, lub sijhawm khaws cia ntawm cov sealant yog qis dua 27 ° C thiab nyob rau hauv qhov chaw txias, qhuav thiab cua nkag. Yog tias qhov chaw khaws cia tiag tiag tsis tuaj yeem ua tau raws li cov xwm txheej teev tseg hauv tus qauv, xws li qhov kub thiab txias siab dhau, lub sijhawm khaws cia ntawm cov sealant yuav luv dua. Txawm tias cov sealant tsis tshaj lub sijhawm khaws cia nominal nyob rau hauv qhov xwm txheej no, qhov tshwm sim ntawm kev kho qeeb yuav tshwm sim.
