Cov ntaub ntawv tseem ceeb thiab cov khoom ntawm qhov rooj thiab qhov rai foob

Qhov rooj thiab lub qhov rai cov foob yog cov ntaub ntawv sib txuas lus tseem ceeb hauv kev tsim kho kev tsim kho, thiab lawv cov kev ua tau ncaj qha cuam tshuam rau lub airtightness, watertightness, thiab lub qhov rooj thiab lub qhov rais. Cov khoom lag luam ntawm thawj cov khoom txiav txim siab nws qhov chaw muaj peev xwm, nyiaj txiag dag zog, thiab lub neej pabcuam. Cov ntaub ntawv nquag muaj xws li Silicone, Polyurethane, Acrylic, thiab Polysulfide Roj Hmab.

 

Silicone sealant yog cov khoom siv hluav taws xob feem ntau yog cov khoom siv hluav taws xob, kev muab cov huab cua zoo, UV tsis kam, thiab ntev- term elasticity. Nws lub ntsiab tseem ceeb, polydimethylsiloxane, yog ruaj khov nyob rau hauv qhov kub ntawm- 50 Qib, ua rau nws muaj kev haum xeeb ntawm cov huab cua. Silicone sealant muaj cov nplaum zoo tshaj plaws rau cov khoom siv hauv tsev (xws li cov iav, hlau, thiab kev xaiv cov khoom zoo rau lub qhov rooj thiab cov pob qij txha lub qhov rai.

Polyurethane seavant, ntawm qhov tod tes, paub rau nws lub zog sib koom ua zog thiab ua kom haum rau qhov rooj thiab qhov rai qauv raug rau kev txav tseem ceeb. Feem ntau muaj ntawm cov polymer ntawm polyols thiab isocyanates, nws ua rau pom kev zoo tshaj plaws thiab lub qhov rooj ntawm lub qhov rooj thiab lub Windows thiab qhov kub hloov pauv. Txawm li cas los xij, Polyurethane sealants yog rhiab rau ya raws, xav tau cov av noo tswj thaum daim ntawv thov. Lawv kuj tseem daj nrog lub caij nyoog raug rau UV teeb.

Acrylic sealants tsis muaj nqi thiab qhuav sai sai, ua rau lawv haum rau lub qhov rais sab hauv thiab lub qhov rais luv luv {}} lub sijhawm sequing kev xav tau. Feem ntau ua los ntawm cov acrylic polymers, lawv muaj cov khoom adhesion thiab zoo nkauj tsis kam thiab ua rau muaj kev tawg lossis hmoov nrog kev siv ntev}.

Cov roj av polysulfide yog feem ntau siv nyob rau hauv high -}}}}}}}}} kawg tsim. Lawv muaj cov huab cua tsis muaj cua hlob heev thiab cov roj ua haujlwm tau zoo, ua rau lawv haum rau cov ntawv thov uas xav tau kev nyab xeeb tshaj plaws.

Cov ntaub ntawv sib txawv rau qhov rooj thiab qhov rai fainnts muaj lawv tus kheej thiab qhov tsis zoo. Thaum xaiv, xav txog cov kev cai ib puag ncig, thov kev thov, thiab pob peev nyiaj txiag los xyuas kom ntev} kev sib khi ntawm lub qhov rooj thiab lub qhov rais.
