FAQS
HPMC lubHydroxypropyl methylcellulose yog siv(INN npe: Hypromellose), kuj yooj yim li hydroxypropyl methylcellulose (HPMC), yog ib hom non-ionic cellulose tov ether. Nws yog semi-synthetic, tsis muaj zog, viscoelastic polymer. Hydroxypropyl methylcellulose yog siv dav hauv kev tsim kho, khoom noj khoom haus, tshuaj, thiab lwm yam lag luam.

HPMC Qauv:
HPMC HS CODE: 3912390000
Chemical Properties:
Cov tsos mob: Dawb los yog zoo li cov hmoov dawb.
Particle loj; 100 mesh pass tus nqi yog ntau tshaj 98.5%; 80 mesh pass tus nqi yog 100%. Qhov loj me ntawm qhov tshwj xeeb tshwj xeeb muaj nyob ntawm 40 txog 60 mesh.
Pom qhov ntom ntom: 0.25-0.70g / cm (feem ntau yog li 0.5g / cm), tshwj xeeb lub ntiajteb txawj nqus 1.26-1.31.
Solubility: Soluble hauv dej thiab qee cov kuab tshuaj, xws li qhov tsim nyog ntawm ethanol / dej, propanol / dej, thiab lwm yam. Cov kua dej aqueous muaj cov dej ua haujlwm. Nrog lub siab transparency thiab ruaj khov kev ua tau zoo, gel kub ntawm txawv specifications txawv, solubility hloov nrog viscosity, viscosity qis dua thiab solubility ntau dua. Kev ua tau zoo ntawm HPMC nrog cov kev qhia tshwj xeeb muaj qhov sib txawv. Kev sib cais ntawm HPMC hauv dej tsis cuam tshuam los ntawm tus nqi PH.
HPMC tsim los ntawm Longou:
Longou tab tom tsim thiab muab ntau hom HPMC thiab HEMC (MODCELL®) rau cov ntawv thov sib txawv. Feem ntau, Longou HPMC muaj ob series HPMC, ib series ntawm HEMC thiab hloov khoom.
Standard hom:
HPMC LK
HPMC LE

Hydroxypropyl methylcellulose (HPMC) yog cellulose ethers uas tau muaj cov pab pawg hydroxyl ntawm cov cellulose saw hloov rau methoxy lossis hydroxypropyl pawg.It yog tsim los ntawm tshwj xeeb etherification ntawm cov paj rwb ntshiab heev cellulose nyob rau hauv alkaline tej yam kev mob. Nyob rau hauv xyoo tas los no, HPMC, raws li cov khoom siv ua haujlwm, feem ntau ua lub luag haujlwmsnyob rau hauv dej tuav thiab thickening nyob rau hauv kev tsim kho kev lag luam thiab yog dav siv nyob rau hauvdrymix mortars, zoo li pobzeb nplaum, grouts, plastering, phab ntsa putty, tus kheej leveling, rwb thaiv tsev mortar thiab lwm yam.
Feem ntau, rau putty hmoov, lub viscosity ntawmHPMCyog txaus ntawm 70,000 mus rau 80,000. Lub ntsiab tseem ceeb yog nyob rau hauv nws cov dej tuav kev ua tau zoo, thaum lub thickening nyhuv yog me me. Rau mortar, cov kev xav tau rauHPMCyog siab dua, thiab cov viscosity yuav tsum nyob ib ncig ntawm 150,000, uas tuaj yeem xyuas kom meej tias nws ua haujlwm zoo dua hauv cov cement mortar. Tau kawg, nyob rau hauv cov hmoov putty, tsuav yog cov dej tuav kev ua tau zoo ntawm HPMC yog qhov zoo, txawm tias cov viscosity tsawg (70,000 txog 80,000), nws tau txais. Txawm li cas los xij, hauv cov cement mortar, nws yog qhov zoo dua los xaiv HPMC nrog cov viscosity loj dua (ntau dua 100,000), vim tias nws cov dej tuav tau ntau dua hauv qhov xwm txheej no.
Qhov teeb meem ntawm putty hmoov tshem tawm feem ntau yog nyob ntawm qhov zoo ntawm calcium hydroxide thiab muaj me ntsis ua rau HPMC. Yog tias cov ntsiab lus calcium ntawm calcium hydroxide tsawg lossis qhov piv ntawm CaO thiab Ca (OH) 2 tsis tsim nyog, nws yuav ua rau cov hmoov putty poob. Hais txog qhov cuam tshuam ntawm HPMC, nws yog qhov tseem ceeb ntawm nws cov dej tuav dej. Yog tias cov dej khaws cia ntawm HPMC tsis zoo, nws kuj tseem yuav muaj qee yam cuam tshuam rau depowdering ntawm putty hmoov.
Cov kev cai rau kev siv cov hmoov putty yog qhov tsawg. Ib qho viscosity ntawm 100,000 yog txaus. Qhov tseem ceeb yog kom muaj cov dej tuav tau zoo. Nyob rau hauv cov nqe lus ntawm mortar, qhov yuav tsum tau muaj kuj siab thiab siab viscosity yog yuav tsum tau, thiab 150,000 cov khoom muaj cov nyhuv zoo dua.
(1) Kev tsim kho kev lag luam: Raws li tus neeg saib xyuas dej thiab rov qab ntawm cov cement mortar, nws ua rau lub tshuab nqus dej. Siv plaster, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev ua cov nplaum los txhim kho kev siv tau thiab ua kom lub sijhawm ua haujlwm ntev. Nws tuaj yeem siv los muab cov pobzeb ceramic, marble, kho kom zoo nkauj yas, muab tshuaj txhuam tus neeg sawv cev, thiab txo cov cement. Cov khoom tuav dej ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab smearing thiab txhim kho lub zog.
(2) Ceramic manufacturing kev lag luam: dav siv los ua adhesives hauv kev tsim cov khoom siv ceramic.h tom qab hardening.
(3) Coatings kev lag luam: Raws li ib tug thickener, dispersant thiab stabilizer nyob rau hauv lub txheej kev lag luam, nws muaj zoo solubility nyob rau hauv dej los yog organic solvents.
(4) Ink printing: Raws li cov thickener, dispersant thiab stabilizer hauv kev lag luam number case, nws muaj zoo solubility nyob rau hauv dej los yog organic solvents.
(5) Plastics: raws li kev tso tawm tus neeg sawv cev, softener, lubricant, thiab lwm yam.
(6) Polyvinyl chloride: Raws li dispersant nyob rau hauv zus tau tej cov polyvinyl chloride, nws yog lub ntsiab pab nyob rau hauv kev npaj ntawm PVC los ntawm ncua kev kawm ntawv polymerization.
(7) Lwm tus: Cov khoom no kuj tau siv dav hauv cov tawv nqaij, cov khoom siv ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia, thiab kev lag luam textile.
