Gypsum board yog ib lub rooj sib tham hauv tsev uas ua los ntawm ntuj gypsum thiab ntsib daim ntawv, nrog rau qhov sib ntxiv ntawm cov fiber ntau, hmoov txhuv nplej siab, accelerators, foaming agents, thiab dej. Nws muaj cov yam ntxwv ua haujlwm hauv qab no:
Tsawg Zog thiab Kev Ua Haujlwm Siab: Lub zog siv rau kev tsim tib chav tsev ntawm gypsum board yog 78% qis dua li cov cement. Nws xav tau kev nqis peev tsawg dua, muaj peev xwm ntau lawm, thiab cov txheej txheem yooj yim, ua kom yooj yim rau cov khoom loj -.
Lub teeb yuag: Siv gypsum board rau cov phab ntsa muab faib ua qhov hnyav uas tsuas yog 1/15 ntawm cov phab ntsa cib ntawm tib lub thickness thiab 1/10 ntawm phab ntsa thaiv. Qhov no muaj txiaj ntsig zoo rau cov qauv av qeeg tiv thaiv thiab tuaj yeem txo tus nqi ntawm cov hauv paus thiab cov khoom siv tseem ceeb.
Thermal rwb thaiv tsev: Kwv yees li 60% ntawm cov tub ntxhais ntawm gypsum board yog tsim los ntawm micropores. Vim tsis muaj thermal conductivity ntawm huab cua, nws muaj lub teeb yuag thermal rwb thaiv tsev zoo heev.
Hluav taws kub Resistance: Txij li thaum lub gypsum core nws tus kheej tsis yog -combustible, thiab nws absorbs ib tug loj npaum li cas ntawm tshav kub thaum lub sij hawm tso tawm ntawm chemically khi cov dej thaum raug hluav taws, ncua qhov nce nyob rau hauv qhov kub thiab txias, gypsum board pom cov hluav taws zoo heev - retardant zog. Raws li kev ntsuam xyuas los ntawm National Fire Protection Testing Center, qhov ntsuas hluav taws kub ntawm gypsum board faib phab ntsa tuaj yeem ncav cuag 4 teev.
Suab rwb thaiv tsev Performance: Ib leeg- cov phab ntsa tsim los ntawm ib qho khoom siv sib sib zog nqus, xws li cov pob zeb aerated lossis nthuav dav perlite board, yuav tsum muaj cov tuab tuab kom ua tau raws li cov kev xav tau ntawm lub suab rwb thaiv tsev. Gypsum board faib phab ntsa, txawm li cas los xij, muaj cov kab noj hniav tshwj xeeb, uas ua rau lub suab rwb thaiv tsev zoo heev.
Kho kom zoo nkauj muaj nuj nqi: Lub du nto ntawm gypsum board, nrog seamless pob qij txha ntawm cov laug cam, tso cai rau kho kom zoo nkauj.
