Tus nqi sam hwm ntawm gypsum yog acidic lossis nruab nrab. Tam sim no muaj ob hom kev tsim khoHydroxyPropyyl MethylcelluloseNtawm kev ua lag luam: qeeb-dissolving cellulose thiab cov cellulose tam sim no. Cov cellulose tam sim no tsis haum rau cov tshuab gypsum. Cov khoom lag luam, cov solubility yog tsis zoo nyob rau hauv cov khoom siv acidic lossis nruab nrab ntawm cov khoom siv hydroxyprropylulose (thaum Gypsum tom qab lub tshuaj khib tau ua rau Phab ntsa rau ib lub sijhawm luv luv, cov pob me me zoo li tshwm sim rau saum npoo). Tam sim no, hauv gypsum cov khoom lag luam, tshwj xeeb tshaj yog nyob rau hauv lub tshuab-sported gyulated lub sij hawm luv heev, uas yuav tsum tau ua txhua lub sijhawm luv luv ntawm cov cellulolt cellulose ether Cov txheej txheem ntau lawm. Cov kev kho deg (tsis yog cov thiaj li hu ntxiv ntawm lwm cov kev sib ntxiv hauv cov qib cellulose qib ether ether), yog li hloov mus rau Gypsum Cug System. HydroxyPropy E ether nrog kev kho kom sib sib zog nqus lub sijhawm thiab muaj peev xwm txhim kho cov theem thiab txhim kho cov txheej txheem cug.
Tshuab-tsuag gypsum tshuaj khib feem ntau siv tau kuj muaj tsawg-viscosity hydrothylropeny etherline ntawm 20,000 ntxiv 0.2% rau 0.4%. Lub rooj teeb tsa lub cav-txau gypsum tshuaj khib yog tswj hwm thaum 1 teev. Peb siv gypsum capield yieldgosity, thixotropy, thixotropy, thixotrotropy, thixotrotropy, thij thiab xwm yeem ntawm slurry los txiav txim cov kev ua tau zoo ntawm gypsum tshuaj.
Peb xav txog kev tswj hwm zoo ntawm desulfurization gypsum cov txheej txheem calcining, fydrers, Mydrotum Methylropy, Mystered Perlite Las, Gypsum Retarder) Qhov kev xaiv ntawm tag nrho Khoom Formula cov nqi tsim txiaj.
HydroxyPropyl methyl cellulose etherRau gypsum tshuaj khib muaj siab ua kom siab thiab ua haujlwm zoo, thiab tau paub dav los ntawm Gypsum Muj Cug Cov Neeg Siv Khoom.
