Methyl hydroxyethyl cellulose (HEMC), raws li qib siab -kev ua haujlwm tsis yog- ionic cellulose ether, tau siv dav hauv ntau yam kev lag luam thiab cov neeg siv khoom vim nws cov thickening zoo heev, dej tuav, dispersing, emulsifying, thiab zaj duab xis - tsim cov khoom.
Cov chaw siv tseem ceeb
Construction and building materials industry: HEMC is a core additive in dry-mix mortar, tile adhesive, putty powder, self-leveling flooring, and other products. It can significantly improve the 24-hour water retention rate of mortar (>85%), tiv thaiv kev poob dej thaum ntxov thiab tawg, thiab txhim kho kev sib koom ua ke thiab tiv thaiv- cov khoom plam. Nws tuaj yeem tswj tau cov dej noo ntau dua 85% txawm tias nyob rau hauv siab - qhov kub thiab txias, tiv thaiv cov cheeb tsam hollow thiab detachment.
Coatings thiab Ink Industry:
Hauv dej-raws li cov xim latex, HEMC muab cov thickening zoo heev thiab rheology tswj cov khoom, ua tiav ib lub tsho tuab txog li 200 μm thiab txhim kho cov khoom tiv thaiv -sagging los ntawm 40%. Nyob rau hauv cov xim pleev xim, nws tuaj yeem txhim kho qhov kev sib raug zoo ntawm cov hmoov pearlescent los ntawm 3 zaug, ua kom pom kev zoo nkauj. Nws kuj tseem siv rau hauv cov ntawv luam tawm los tiv thaiv cov xim sedimentation thiab txhim kho kev ruaj ntseg cia.
Pharmaceutical thiab Pharmaceutical Industry:
HEMC tsis yog - tshuaj lom thiab tsis yog - khaus khaus, teev raws li GRAS (Feem ntau pom tau tias muaj kev nyab xeeb), thiab dav siv los ua ib qho kev txhawb nqa - tso tawm cov khoom siv hauv qhov ncauj cov ntsiav tshuaj thiab cov tshuaj ncua. Nws tuaj yeem ua tiav qhov kev tso tawm ruaj khov rau 12 teev, nrog rau cov tshuaj ntshav siab hloov pauv CV% tsawg dua lossis sib npaug li 15%, txhim kho kev nyab xeeb thiab ua raws li cov tshuaj.
Kev lag luam zaub mov:
Raws li cov khoom noj khoom haus ntxiv, HEMC yog siv los ua cov thickener, stabilizer, thiab los tiv thaiv- tus neeg sawv cev yaj. Hauv dej khov, nws tuaj yeem tswj cov dej khov siv lead ua loj rau<15μm, improving melt resistance by 60% and resulting in a smoother, more delicate texture. It can also be used in jams and sauces to improve texture and suspension stability.
Tshuaj Txhua Hnub:
Dav siv nyob rau hauv cov tshuaj txhuam hniav, tshuaj ntxuav lub ntsej muag, da dej gels, tshuaj pleev ib ce, thiab lwm yam khoom raws li ib tug thickener, emulsifier, thiab moisturizer. Nws cov pseudoplasticity zoo heev ua rau cov khoom lag luam yooj yim rau extrude thiab sib kis, ua rau nyias, ua pa tiv thaiv zaj duab xis thiab txhim kho cov neeg siv kev paub.
Roj Drilling thiab Oilfield Development:
HEMC muaj cov ntsev zoo heev thiab siab - qhov kub thiab txias, ua kom ruaj khov viscosity txawm nyob ntawm 120℃thiab siab salinity. Nws yog siv rau thickening drilling kua, txo filtration poob, thiab tshem tawm cuttings, kom ntseeg tau tias drilling kev nyab xeeb.
Roj Drilling thiab Oilfield Development:
HEMC nthuav tawm cov ntsev zoo heev thiab siab - qhov kub thiab txias, tuav ruaj khov viscosity ntawm 120℃thiab hauv siab -salinity ib puag ncig. Nws yog siv rau thickening drilling kua, txo filtration poob, thiab tshem tawm cuttings, kom ntseeg tau tias drilling kev nyab xeeb. Kev Tiv Thaiv Ib puag ncig thiab Kev Kho Dej: Nws muaj peev xwm adsorption muaj zog rau cov hlau hnyav ions, tshwj xeeb tshaj yog hexavalent chromium (Cr⁶⁺), nrog rau kev tshem tawm ntawm 99.3% thiab muaj peev xwm adsorption txog li 320 mg / g, uas qhia tau hais tias muaj txiaj ntsig zoo hauv kev kho dej khib nyiab.
