HydroxyPropyl methyl cellulose ether (HPMC)

Nta:
① Nrog dej zoo ceev, thickening, rheology thiab adhesion, nws yog thawj cov khoom siv raw rau kev txhim kho cov khoom siv tsev thiab cov khoom siv hniav.
②wide ntau yam ntawm kev siv: vim yog tiav qib kawm, nws tuaj yeem siv rau txhua lub tsev cov ntaub ntawv. 
③SMALS DOSAGE: 2-3 kg ib tuj ntawm hmoov tsev cov ntaub ntawv vim qhov siab zoo.
Cov khoom lag luam kub siab tiv taus: dej rov qab tus nqi ntawm HPMC cov khoom lag luam dav hlau yuav txo qis nrog qhov ntsuas kub. Nyob rau hauv sib piv, peb cov khoom tuaj yeem ua lub tshuaj khib muaj cov dej rov qab nce siab thaum qhov ntsuas kub nce txog 30-40 ° C. Cov dej ruaj khov ceev txawm tias kub rau 48 teev.
⑤good solubility: nyob rau hauv chav tsev kub, ntxiv dej thiab do rau li 5 feeb, cia nws zaum li 5 feeb, thiab tom qab ntawd do kom yaj. Kev rhuav tshem tau nrawm ntawm Ph8-10. Kev daws tau muab tso rau lub sijhawm ntev thiab muaj kev ruaj khov zoo. Hauv cov khoom sib xyaw qhuav, qhov ceev ntawm dispersing thiab yaj hauv dej yog qhov zoo tagnrho.

Lub luag haujlwm ntawm HPMC hauv cov hmoov huv huv

Nyob rau hauv cov hmoov chot, methyl cellulose cellulose ua lub luag haujlwm ntawm dej khaws cia, thickening thiab txhim kho kev tsim kho kev ua haujlwm. Cov dej zoo khaws cia ua tau zoo tias lub tshuaj khib yuav tsis ua rau sanding, hmoov thiab muaj zog daws teeb meem thiab tsis ua tiav kev ua tsis tiav; Lub zog cickening zoo heev rau cov qauv tshuaj khib nyiab ntawm lub ntsej muag ntub dej, yog li txhim kho cov tshuaj khib nyiab ntawm phab ntsa thiab txo cov khib nyiab.

Feem ntau hais lus, ntau dua cov viscosity, qhov zoo dua cov dej khaws cov nyhuv khaws cia. Txawm li cas los xij, qhov siab dua viscosity, ntau dua cov molecular hnyav ntawm MC, thiab nws solubility yuav muaj kev cuam tshuam tsis zoo rau lub zog thiab kev tsim kho ntawm lub tshuaj khib. Qhov siab tshaj lub viscosity, qhov pom ntau ntxiv rau cov nyhuv tuab rau ntawm lub tshuaj khib, tab sis nws tsis ncaj ncaj ncaj. Qhov siab tshaj lub viscosity, ntau ntau ntau lub volt ntub lub cug yuav. Thaum kev tsim kho, nws yog manifested raws li sticking rau tus scraper thiab siab adhesion rau lub substrate. Tab sis nws tsis muaj txiaj ntsig zoo rau kev nce cov txheej txheem lub zog ntawm lub txiv ntoo qhuav nws tus kheej.

Lub cev thiab tshuaj lom neeg:

1. Pom: Dawb lossis tawv nqaij dawb.
2. Paus Loj Loj: 80-100 Mesh Pass tus nqi yog ntau dua 98.5%; 80 Mesh Pass tus nqi yog 100%.
3. Cov pa roj cua kub: 280-300 ° C
4. Pom meej ntom ntom: 0.25-0.70 / cm3 (feem ntau nyob ib ncig ntawm 0.5 / cm3), tshwj xeeb lub ntiajteb txawj nqus 1.26-1.31.
5. Txhaum Kub Kub: 190-200 ° C.
6. Sab nro: 2% kev daws teeb meem yog 42-56Dyn / CM3.
7. Soluble hauv dej thiab qee cov kuab tshuaj, dej, propanol / Dej, trichloroethane, thiab lwm yam nyob rau hauv cov protortions tsim nyog. Cov kev daws teeb meem yog cov nquag ua haujlwm. Siab transparency thiab ruaj khov ua tau zoo. Cov khoom sib txawv ntawm cov khoom muaj ntau qhov chaw kub sib txawv, thiab cov solubility hloov nrog viscosity. Qhov qis dua viscosity, muaj ntau dua cov solubility. Cov kev sib txawv ntawm HPMC muaj qee qhov sib txawv hauv kev ua tau zoo, thiab kev sib txawv ntawm HPMC hauv dej tsis cuam tshuam los ntawm tus nqi PH.
8. Nrog rau kev txo cov ntsiab methoxyl, cov dej solubility ntawm HPMC txo qis, thiab cov dej num saum npoo av kuj txo qis.
9. HPMC kuj muaj cov yam ntxwv ntawm thickening lub peev xwm, ntsev tsis kam, thiab muaj ntau yam kev ruaj khov, thiab ntau yam thiab sib cais.

Lub hom phiaj tseem ceeb:

1. Kev lag luam kev tsim kho: raws li cov dej-tuav cov neeg sawv cev thiab retarder rau cov cement cug, nws tuaj yeem ua rau lub tshuaj khib twj tso kua mis. Siv los ua cov phau ntawv hauv plaster, plaster, putty hmoov lossis lwm yam khoom siv hauv tsev los txhim kho lub sijhawm ua kom tiav thiab lub sijhawm ntev. Nws tuaj yeem raug siv ua cov pob zeb muab tshuaj txhuam, Marble, Yas kho kom zoo nkauj, thiab tuaj yeem txo tus nqi ntawm xis mas. Cov dej-khaws cov kev ua tau zoo ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim tias ziab nrawm dhau tom qab daim ntawv thov, thiab txhim kho lub zog tom qab ua kom tawv.
2. Kev lag luam tej hub
3. Txheej kev lag luam: nws tau siv los ua cov tuab dua, dispersant thiab stabilizer nyob rau hauv txheej kev lag luam, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Tuaj yeem siv rau hauv cov xim tshem tawm.
4. Ink Printing: Nws yog siv los ua cov tuab dua, dispersant thiab stabilizer nyob rau hauv kev lag luam hauv Ink, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic.
