Tus sawv cev
Feem ntau siv yog borax, poov tshuaj sodium sartrate, thiab citric acid. Lawv raug siv los kho lub sijhawm teeb tsa ntawm Gypsum slurry thiab ua kom muaj cov txheej txheem tswj khoom lag luam.
3 fiber kev txhawb zog
Ntxiv cov iav fiber ntau, cov ntawv fiber ntau, thiab polypropylene fiber (5%-15%) txhim kho lub rooj tsavxwm tawm tsam, muaj zog, thiab lub zog yooj yim.
4 Cov Tshuaj Tiv Thaiv Tsis Muaj Dej
Txog kev ywg dej yuav tsum tau, silicone lossis cov neeg ua haujlwm tsis muaj duab tso quav yog ntxiv rau kev txhim kho lub rooj tsavxwm noo noo.
5 Lwm Yam Ntxiv Ntxiv
Foaming cov neeg sawv cev txo lub zog ceev, thaum txhawb cov neeg sawv cev (xws li Silica Fume thiab yoov tshauv) nce lub zog. Cov khoom ntxiv no ntxiv raws li cov khoom lag luam khoom.
6 Txheej Txheem Ntau Lawm
Cov khoom xyaw thiab kev sib xyaw: gypsum hmoov thiab lwm yam ntaub ntawv tau tshwm sim hauv cov proportions tsim nyog, ces dej thiab ntxiv ntxiv los ua cov slurry.
7 Moulding: moulding yog ua siv slurry lossis compression moulding txoj kev, nrog tswj thickness (9-25mm).
8 kho: Tom qab thawj zaug teeb tsa, cia kom sawv ntsug lossis kho khaub ncaws (50-70 degree) kom nrawm dua.
9 TXIAV THIAB QHUAV: TOM QAB DUAB: Tom qab ziab, txiav kom cov ntsiab lus tshwj xeeb thiab tshem tawm cov ntsiab lus pub dawb rau tsawg dua lossis sib npaug rau 2%.
