Hauv cov khoom siv hauv tsev, nws yog siv los ua tus neeg saib xyuas dej thiab rov qab rau cov cement sludge nrog twj tso kua mis.Nws tuaj yeem siv los ua cov ntaub ntawv hauv plaster, gypsum, inverted hmoov lossis lwm yam khoom siv hauv tsev los txhim kho kev sib kis thiab ua haujlwm ntev.Nws tuaj yeem siv los ua tus neeg sawv cev rau cov cib, cov vuas, marbles, yas kho kom zoo nkauj, thiab kev sib txuas ua ke.Nws kuj tuaj yeem txo cov cement.Kev ruaj ntseg ntawm cov dejHPMCtiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab txheej, thiab txhim kho lub zog tom qab hardening.

Tsis tas li ntawd, nws yog siv los ua thickener, stability, emulsifier, excipient, dej tuav nyob rau hauv zus tau tej cov lwm yam petrochemicals, coatings, tsev cov ntaub ntawv, xim tshem tawm, ua liaj ua teb chemicals, inks, textile printing thiab dyeing, ceramics, papermaking, thiab cosmetic hom.Tus neeg saib xyuas, tus neeg ua yeeb yaj kiab tsim, thiab lwm yam.

1. Cov tsos mob: dawb los yog yuav luag dawb hmoov, tsw tsw thiab saj.

2. Granularity: 10 mesh pass tus nqi yog ntau dua 98.5%;80 mesh pass tus nqi yog ntau dua 100%.

3. Carbonization kub: 280-300 ℃.

4. Chav ceev: 0.25-0.7G / CM3 (feem ntau yog 0.5G / CM3), qhov tshwj xeeb lub ntiajteb txawj nqus yog 1.26-1.31.

5. Discoloration kub: 190-200 ℃.

Txoj kev tsim khoom

Cov paj rwb refined cellulose yog kho nrog lye ntawm 35-40 ° C rau ib nrab ib teev, nyem, lub cellulose yog crushed, thiab zoo hnub nyoog ntawm 35 ° C, thiaj li hais tias cov tau alkali fiber nruab nrab degree ntawm polymerization nyob rau hauv qhov yuav tsum tau ntau yam.Muab cov alkali fiber ntau tso rau hauv etherification kettle, ntxiv propylene oxide thiab methyl chloride txuas ntxiv, thiab etherify ntawm 50-80 ℃ rau 5h, qhov siab tshaj plaws yog li 1.8MPa.Tom qab ntawd ntxiv cov tshuaj hydrochloric acid thiab oxalic acid kom tsim nyog los ntxuav cov ntaub ntawv hauv dej kub ntawm 90 ° C kom nce ntim.Dehydrate nrog lub centrifuge.Ntxuav kom nruab nrab.Thaum cov dej ntsiab lus hauv cov khoom tsawg dua 60%, qhuav nws nrog cov kwj ntawm cov cua kub ntawm 130 ℃ mus rau tsawg dua 5%.Thaum kawg, nws yog crushed los ntawm 20-mesh sieve kom tau cov khoom tiav.
