Kev faib tawm Cellulose Ether Cellulose ether yog ib lo lus dav dav rau cov khoom tsim los ntawm cov tshuaj tiv thaiv ntawm alkali cellulose thiab etherifying tus neeg sawv cev nyob rau hauv qee qhov xwm txheej. Thaum alkali cellulose raug hloov los ntawm cov neeg sawv cev etherifying sib txawv, cov cellulose ethers sib txawv yuav tau txais. Ac...Nyeem ntxiv»

Hydroxyethyl Cellulose Lub Cev thiab Tshuaj Lom Zem Cov yam ntxwv ntawm cov khoom no yog dawb rau lub teeb daj fibrous lossis powdery khoom, tsis muaj tshuaj lom thiab tsis muaj saj Melting point 288-290 ° C (dec.) Ceev 0.75 g / mL ntawm 25 ° C (lit.) Solubility Soluble hauv dej. Insoluble hauv cov organic daws teeb meem ...Nyeem ntxiv»

Hydroxyethyl cellulose yog qib viscosity nruab nrab mus rau siab ntawm cellulose ether, siv ua cov khoom tuab thiab stabilizer rau cov txheej txheem dej, tshwj xeeb tshaj yog thaum qhov viscosity cia siab thiab qhov viscosity daim ntawv thov qis. Cellulose ether yooj yim rau disperse hauv dej txias nrog pH tus nqi ≤ 7, tab sis ...Nyeem ntxiv»

1 Kev Taw Qhia Cellulose ether (MC) yog siv dav hauv kev lag luam khoom siv hauv tsev thiab siv ntau heev. Nws tuaj yeem siv ua tus neeg tiv thaiv, tus neeg sawv cev khaws dej, ua kom tuab thiab nplaum. Hauv cov mortar qhuav sib xyaw, mortar rwb thaiv tsev sab nraud, mortar tus kheej, nplaum pobzeb, high-p...Nyeem ntxiv»

Cov hmoov polymer uas tawg tau dua feem ntau pom hauv kev tsim kho ua cov khoom siv rwb thaiv tsev phab ntsa sab nraud. Nws feem ntau yog ua los ntawm cov khoom polystyrene thiab cov hmoov polymer, yog li nws tau txais lub npe rau nws qhov tshwj xeeb. Hom hmoov polymer tsim kho no feem ntau yog tsim los rau qhov tshwj xeeb ntawm polys...Nyeem ntxiv»

Tom qab ntxiv hydroxypropyl methylcellulose rau cov ntaub ntawv cement, nws tuaj yeem tuab. Qhov ntau ntawm hydroxypropyl methylcellulose txiav txim siab qhov xav tau dej ntawm cov ntaub ntawv cement, yog li nws yuav cuam tshuam rau cov zis ntawm mortar. Muaj ntau yam cuam tshuam rau viscosity ntawm hydroxypropyl methylcellulose:...Nyeem ntxiv»

Hauv kev tsim cov vuas ceramic phab ntsa thiab pem teb, ntxiv cov neeg sawv cev txhawb nqa lub cev ceramic yog qhov ntsuas zoo los txhim kho lub zog ntawm lub cev, tshwj xeeb tshaj yog rau cov vuas porcelain nrog cov ntaub ntawv loj, nws cov nyhuv yog qhov pom tseeb dua. Niaj hnub no, thaum cov peev txheej av nplaum zoo tau nce ntxiv ...Nyeem ntxiv»

Vim muaj tej yam xws li qhov kub thiab txias ntawm huab cua, av noo, cua hlob, thiab cua ceev, qhov volatilization ntawm cov dej noo hauv cov khoom gypsum-based yuav raug cuam tshuam. Yog li ntawd, txawm tias nws yog nyob rau hauv gypsum-based leveling mortar, caulk, putty, lossis gypsum-based self-leveling, hydroxypropyl methylcellulose ether (HPMC)...Nyeem ntxiv»

1. Cov khoom siv raw ntawm cellulose ether Cellulose ether rau kev tsim kho yog cov polymer uas tsis yog ionic uas yaj tau hauv dej uas nws qhov chaw yog: Cellulose (ntoo pulp lossis paj rwb linter), halogenated hydrocarbons (methane chloride, ethyl chloride lossis lwm yam halides ntev), epoxy compounds (ethylene oxide, propylene oxi...Nyeem ntxiv»

Hydroxypropyl methylcellulose - masonry mortar Txhim kho qhov lo rau ntawm masonry, thiab txhim kho qhov khaws dej, kom lub zog ntawm cov mortar tuaj yeem txhim kho. Txhim kho lubricity thiab plasticity rau cov khoom siv zoo dua, kev siv yooj yim dua txuag lub sijhawm thiab txhim kho ...Nyeem ntxiv»

Hydroxypropyl methylcellulose, hu ua: HPMC lossis MHPC. Qhov tsos yog hmoov dawb lossis dawb tawm; qhov siv tseem ceeb yog ua tus neeg tawg ua rau hauv kev tsim cov polyvinyl chloride, thiab nws yog tus neeg sawv cev tseem ceeb rau kev npaj PVC los ntawm kev ncua polymerization. Hauv cov txheej txheem tsim kho...Nyeem ntxiv»
