Hom Khoom Sealant

Cov ntaub ntawv sealant tuaj yeem muab faib ua ntau hom raws li lawv cov tshuaj muaj pes tsawg leeg, kho cov txheej txheem, thiab cov yam ntxwv ua haujlwm. Txhua hom muaj cov khoom sib txawv thiab tsim nyog rau cov txheej txheem sib txawv thiab kev siv ib puag ncig. Kev xaiv zoo ntawm hom sealant yog qhov tseem ceeb rau kev ua kom muaj kev sib khi ua haujlwm tau zoo thiab ua haujlwm ntev -.

Raws li cov tshuaj muaj pes tsawg leeg, sealants feem ntau suav nrog silicone-raws li, polyurethane-raws li, acrylic-raws li, thiab polysulfide cov ntaub ntawv. Silicone sealants muaj cov huab cua zoo heev thiab kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias, ua rau lawv haum rau cov ntaub thaiv phab ntsa, iav façades, thiab lwm yam kev siv sab nrauv. Polyurethane sealants muab siab elasticity thiab muaj zog adhesion, ua rau lawv zoo tagnrho rau expansion pob qij txha thiab pob qij txha pob qij txha uas yuav tsum tau muaj kev txav chaw. Acrylic sealants yog ib qho yooj yim rau kev thov thiab ib puag ncig tus phooj ywg, feem ntau yog siv rau kev kho kom zoo nkauj sab hauv thiab qis - txav pob qij txha. Polysulfide sealants paub txog lawv cov roj ua haujlwm zoo thiab muaj tshuaj lom neeg, thiab feem ntau siv rau hauv kev lag luam ib puag ncig thiab kev tshaj xov xwm tshwj xeeb.

Hais txog kev kho cov txheej txheem, cov sealants tuaj yeem muab faib ua cov dej noo-kho, oxidative-kho, thiab kub- hom melting. Moisture- kho sealants harden thaum raug rau ambient humidity thiab yog dav siv vim lawv yooj yim. Oxidative- kho sealants maj mam harden los ntawm cov tshuaj tiv thaiv nrog oxygen nyob rau hauv cov huab cua thiab haum rau tej yam kev mob ntawm daim ntawv thov. Kub-melting sealants yuav tsum tau cua sov ua ntej daim ntawv thov thiab tsim ib tug ruaj khov foob thaum txias, feem ntau yog siv nyob rau hauv industrial ntau lawm thiab cov khoom tshwj xeeb.

Tsis tas li ntawd, cov sealants tseem tuaj yeem raug cais raws li lawv lub cev, xws li muab tshuaj txhuam - hom sealants, elastic sealants, thiab preformed sealing strips. Cov ntaub ntawv sib txawv no sib txawv hauv cov txheej txheem kev thov thiab cov chaw tsim khoom tsim nyog, tso cai xaiv hloov tau raws li qhov yuav tsum tau ua.

Zuag qhia tag nrho, cov ntaub ntawv sealant tuaj nyob rau hauv ntau hom, txhua tus muaj qhov tshwj xeeb ua tau zoo thiab daim ntawv thov. Hauv kev tsim qauv tsim qauv, kev xaiv yuav tsum yog raws li cov yam ntxwv ntawm cov qauv, ib puag ncig, thiab cov kev xav tau ua haujlwm kom ntseeg tau ntev -lub sij hawm ruaj khov thiab txhim khu kev qha sealing kev ua tau zoo.
