Cov txheej txheem ntau lawm ntawm gypsum board ntau lawm kab feem ntau suav nrog cov kauj ruam tseem ceeb xws li kev npaj cov khoom siv raw, batching, molding, ziab, txiav kom ntev, thiab tom qab- ua. Tag nrho cov txheej txheem yog automated, ua kom muaj txiaj ntsig zoo ntawm kev siv gypsum lossis kev lag luam los ntawm - khoom gypsum (xws li desulfurized gypsum).
1. Kev npaj cov khoom nyoos
Raw Material Source: Feem ntau siv lub tsev gypsum, tab sis desulfurized gypsum, phosphogypsum, thiab lwm yam kev lag luam los ntawm -cov khoom gypsum kuj tseem siv tau, ua tiav cov peev txheej rov ua dua tshiab.
Ua ntej-kev kho mob: Cov khoom siv raw tau hloov mus rau hauv cov khoom siv hemihydrate gypsum hmoov (CaSO₄·0.5H₂O) los ntawm kev sib tsoo, ziab, thiab calcination txheej txheem, thiab tom qab ntawd xa mus rau hauv lub thawv ntim khoom ntawm lub tshuab pneumatic conveying rau siv tom qab.
2. Cov khoom xyaw thiab sib tov
Ntau yam khoom pab tau raug ntsuas raws qhov sib npaug:
Pulp Kev Npaj: Hloov cov hmoov txhuv nplej siab, rov qab, cov ntaub so ntswg, dej -txo tus neeg sawv cev, thiab cov dej sib xyaw rau hauv hydrapulper los ua cov slurry nyoos, uas tom qab ntawd muab cia rau hauv lub tank slurry;
Foaming Agent: Tom qab sib tov nrog dej, nws yog rhuab mus rau saum 35℃kom tswj nws cov dej num;
Accelerator thiab Gypsum Powder: Nkag mus rau hauv silo ntawm lub tshuab nqa.
Tag nrho cov ntaub ntawv raw yog tov rau hauv ib lub tov khoom los tsim ib qho gypsum slurry. Tag nrho cov txheej txheem yog tswj los ntawm ib qho kev tswj tsis siv neeg los xyuas kom meej cov proportions ruaj khov.
3. Moulding
Cov ntaub ntawv sab saud thiab sab qis yog qhov tsis sib haum, raug kho, thiab tau qhab nia ua ntej nkag mus rau hauv lub tshuab molding;
Lub gypsum slurry yog sib npaug ntawm cov ntawv qis thiab extruded nyob rau hauv lub tshuab molding los tsim ib lub slab;
Lub tshuab hydraulic tsis siv neeg moulding tshuab (xws li LB-4 qauv), ua ke nrog silicone tub ntxhais raj thiab pneumatic expansion tshuab, ua tiav high-precision molding thiab txo tus nqi tawg; Ob lub gypsum boards tuaj yeem molded ib zaug, txhawb kev tsim ntau yam thicknesses los ntawm 60-150mm.
4. Solidification thiab conveying
Lub slab undergoes thawj zaug thiab zaum kawg solidification ntawm ib tug solidification siv. Tom qab ntawd nws raug xa mus rau qhov ruaj khov -ntev txiav tshuab los ntawm cov khoom siv conveyor rau kev txiav rau cov qauv ntev (xws li 2400mm, 3000mm). Txiav qhov tseeb ncav cuag ± 0.3mm, ua kom ntseeg tau los ntawm laser ntau yam thiab chav tswj infrared.
5. Qhuav
Cov cua kub cua tshuab ziab khaub ncaws yog siv, feem ntau muab faib ua ntau qhov chaw kub (xws li, 2-6 thaj tsam), tswj qhov nkhaus kom qhuav kom tsis txhob dhau- ziab lossis qis dua - ziab. Qhov chaw tshav kub tuaj yeem yog roj roj, roj, lossis cov roj cua kub cua sov; qee lub tshuab tau nruab nrog cov khoom siv hluav taws xob pov tseg kom txuag hluav taws xob. Lub sij hawm ziab yog kwv yees li 30-60 feeb, txo cov dej noo ntawm cov slab kom qis dua 0.5%.
