Dab tsi yog qhov teeb meem feem ntau uas lub sealant tuaj yeem ua tsis tau?

Nyob rau hauv lub qhov rooj thiab qhov rais, sealants yog tsuas yog siv rau kev sib koom sealing ntawm lub qhov rais thav duab thiab iav, thiab kev sib koom sealing ntawm lub qhov rais thav duab thiab sab hauv thiab sab nrauv phab ntsa.Cov teeb meem ntawm daim ntawv thov sealant rau lub qhov rooj thiab qhov rais yuav ua rau tsis ua hauj lwm ntawm lub qhov rooj thiab qhov rais sealing, uas ua rau cov dej to, huab cua to thiab lwm yam teeb meem, uas yuav cuam tshuam rau tag nrho qhov zoo ntawm lub qhov rooj thiab qhov rais.Qhia qee qhov teeb meem hauv daim ntawv thov sealant rau lub qhov rooj thiab qhov rais, thiab muab cov kev daws teeb meem los ntawm kev txheeb xyuas cov laj thawj los pab cov neeg siv kom zoo siv cov sealant.Ua ntej tshaj plaws, kuv yuav qhia txog cov teeb meem uas tshwm sim: kev tsis sib haum xeeb, kev sib raug zoo tsis zoo, thiab teeb meem khaws cia.

① Tsis sib xws

Qee cov khoom siv siv hauv qhov rooj thiab qhov rais sib dhos, xws li cov ntaub ntawv roj hmab (cov ntaub ntawv roj hmab, cov roj hmab strips, thiab lwm yam), feem ntau muaj kev sib cuag nrog cov sealant.Txawm li cas los xij, qee cov khoom siv roj hmab tuaj yeem ntxiv roj hmab lossis lwm yam khoom siv me me uas tsis sib haum nrog lub sealant system vim yog cov chaw tsim khoom txo nqi lossis lwm yam kev xav.Thaum cov khoom siv roj hmab no nyob rau hauv kev sib cuag nrog silicone sealant, roj hmab roj hmab los yog lwm yam khoom me me yuav tsiv mus rau lub sealant, thiab txawm tsiv mus rau qhov chaw ntawm lub sealant.Thaum siv, nyob rau hauv qhov kev txiav txim ntawm tshav ntuj thiab ultraviolet rays, lub sealant yuav daj.Qhov tshwm sim no yog pom tseeb dua ntawm qhov rooj thiab qhov rais adhesives nrog cov xim sib dua.

Yog li ntawd, peb pom zoo tias ua ntej lubsealantyog thov, qhov kev xeem sib raug zoo ntawm cov sealant thiab cov ntaub ntawv uas nws tiv tauj yuav tsum tau ua raws li txoj kev sim compatibility nyob rau hauv Appendix A ntawm GB 16776 los txiav txim siab compatibility ntawm sealant thiab lub substrate, thiab raws li txoj kev xeem compatibility.Kev tsim kho tau ua tiav raws li qhov yuav tsum tau ua los ntawm cov txiaj ntsig kev xeem.

② Kev sib txuas tsis zoo

Hauv daim ntawv thov ntawm qhov rooj thiab qhov raissilicone sealant,cov substrates uas tuaj yeem sib cuag yog iav, txhuas, cement mortar, ceramic pobzeb, pleev xim rau phab ntsa, thiab lwm yam. Tej zaum yuav muaj roj, plua plav lossis lwm yam khoom seem ntawm cov khoom siv no.Yog tias qhov adhesion tsis tau lees paub ua ntej kev tsim kho, nws yuav ua rau tsis zoo adhesion ntawm lub qhov rooj thiab lub qhov rais silicone sealant.Thaum lub silicone sealant yog siv ntawm kev sib koom ua ke ntawm lub qhov rooj thiab qhov rais thiab sab nrauv phab ntsa ntawm cov cement mortar, yog cov hmoov av thiab cov xuab zeb ntawm lub nto ntawm cov cement mortar ntawm phab ntsa sab nraud tsis raug ntxuav, tej zaum yuav muaj qhov tshwm sim ntawm kev tsis sib txuas tom qab lub sealant kho.

Yog li ntawd, nyob rau hauv cov txheej txheem tiag tiag ntawm kev siv silicone sealant, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov pretreatment ntawm qhov chaw ntawm lub substrate yuav tsum tau adhered, thiab siv cov txheej txheem tsim nyog los tshem tawm cov roj, plua plav, xuab zeb, yooj yim kom poob tawm ntawm cov khaubncaws sab nraud povtseg.

③ Sealant cia teeb meem

Sealantcov 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 cia.Yog hais tias lub sealant tau dhau nws lub txee lub neej, nws yuav zoo li qhov kev kho mob yuav qeeb qeeb, kho tsis zoo lossis tsis kho.

Raws li qhov yuav tsum tau muaj ntawm kev cia khoom nyob rau hauv cov qauv tsim ntawm sealants, lub sij hawm nominal cia ntawm sealants yog qis dua 27 ° C thiab nyob rau hauv txias, qhuav thiab ventilated tej yam kev mob.Yog tias qhov chaw khaws cia hauv kev siv tiag tiag tsis tuaj yeem ua tau raws li cov xwm txheej tau teev tseg hauv tus qauv, xws li qhov kub thiab txias ambient siab dhau lawm, lub sij hawm cia ntawm lub sealant yuav luv luv.Txawm hais tias lub sealant tsis pub dhau lub sijhawm nominal cia nyob rau hauv cov xwm txheej no, qhov tshwm sim ntawm kev kho qeeb yuav tshwm sim.
