Dab tsi yog cov khoom ntawm lub tsev gypsum?

Lub tsev gypsum, feem ntau hu ua plaster ntawm Paris, yog ntau yam khoom siv dav siv hauv kev tsim kho rau ntau yam kev siv xws li plastering phab ntsa thiab qab nthab, tsim cov khoom zoo nkauj, thiab ua pwm thiab cam khwb cia. Nov yog qee qhov tseem ceeb ntawm lub tsev gypsum:

1. Teem Sijhawm: Lub tsev gypsum feem ntau muaj lub sijhawm luv luv, txhais tau tias nws hardens sai sai tom qab sib xyaw nrog dej. Qhov no tso cai rau kev siv tau zoo thiab ua tiav cov haujlwm tsim kho sai.
2. Kev ua haujlwm tau zoo: Gypsum ua haujlwm tau zoo, tso cai rau nws yooj yim zoo li, molded, thiab kis mus rau qhov chaw thaum lub sij hawm plastering lossis molding txheej txheem. Nws tuaj yeem siv tau yooj yim kom ua tiav qhov xav tau thiab cov ntsiab lus.
3. Adhesion: Gypsum nthuav tawm zoo adhesion rau ntau yam substrates, suav nrog masonry, ntoo, hlau, thiab phab ntsa ntub dej. Nws tsim cov ntawv cog lus muaj zog nrog cov chaw, muab cov khoom siv ruaj khov thiab kav ntev.
4. Compressive Strength: Txawm hais tias gypsum plaster tsis muaj zog li cov ntaub ntawv cement, nws tseem muab lub zog txaus compressive rau feem ntau siv sab hauv xws li phab ntsa plastering thiab zoo nkauj molding. Lub zog compressive tuaj yeem sib txawv nyob ntawm kev tsim thiab kho cov mob.
5. Kev Tiv Thaiv Hluav Taws Xob: Gypsum yog qhov muaj hluav taws kub-tiv taus, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws kub hauv cov tsev. Gypsum plasterboard (drywall) feem ntau yog siv los ua cov khoom siv hauv ob sab phlu thiab qab nthab los txhim kho kev nyab xeeb ntawm hluav taws.
6. Thermal rwb thaiv tsev: Gypsum plaster muaj ib co degree ntawm thermal rwb thaiv tsev zog, pab txhim kho lub zog efficiency ntawm lub tsev los ntawm kev txo cov cua kub hloov mus rau hauv cov phab ntsa thiab qab nthab.
7. Suab rwb thaiv tsev: Gypsum plaster pab txhawb lub suab rwb thaiv tsev los ntawm absorbing thiab dampening suab nthwv dej, yog li txhim kho lub acoustics ntawm sab hauv qhov chaw. Nws feem ntau yog siv rau hauv daim ntawv thov soundproofing rau phab ntsa thiab qab nthab.
8. Pwm Resistance: Gypsum resistant rau pwm thiab mildew kev loj hlob, tshwj xeeb tshaj yog thaum ua ke nrog additives uas inhibit microbial kev loj hlob. Cov cuab yeej no pab tswj cov huab cua zoo hauv tsev thiab tiv thaiv kev txhim kho cov teeb meem pwm hauv cov tsev.
9. Shrinkage Control: Lub tsev gypsum formulations yog tsim los txo qis shrinkage thaum lub sij hawm teem thiab kho, txo qhov yuav tshwm sim ntawm cov kab nrib pleb nyob rau hauv lub tiav plaster nto.
10. Versatility: Gypsum tuaj yeem siv rau ntau yam kev siv hauv kev tsim kho, suav nrog plastering, hniav molding, sculpting, thiab casting. Nws tuaj yeem hloov kho tau yooj yim thiab zoo li tus kom ua tiav ntau yam kev tsim qauv zoo nkauj thiab cov qauv vaj tsev.

lub tsev gypsum muaj kev sib xyaw ua ke ntawm cov khoom tsim nyog xws li kev ua haujlwm, kev ua haujlwm, kev sib txuas, hluav taws kub, thiab suab rwb thaiv tsev, ua rau nws yog ib qho khoom siv tseem ceeb hauv kev tsim kho niaj hnub. Nws versatility thiab kev ua tau zoo yam ntxwv ua rau nws haum rau ob qho tib si haumxeeb thiab zoo nkauj daim ntaub ntawv nyob rau hauv vaj tse, coj mus muag, thiab lub tsev.
