Hydroxypropyl Methyl Cellulose Ether (HPMC)

Nta:
① Nrog kev tuav dej zoo, thickening, rheology thiab adhesion, nws yog thawj qhov kev xaiv raw khoom rau kev txhim kho cov khoom siv hauv tsev thiab cov khoom siv zoo nkauj.
② Kev siv ntau yam: vim ua tiav qib, nws tuaj yeem siv rau txhua cov khoom siv hauv tsev. 
③ Kev siv me me: 2-3 kg ib tuj ntawm cov khoom siv hauv tsev vim zoo.
④ Zoo kub tsis kam: cov dej tuav tus nqi ntawm cov khoom HPMC dav dav yuav txo qis nrog qhov kub thiab txias. Hauv qhov sib piv, peb cov khoom tuaj yeem ua rau cov mortar muaj cov dej tuav ntau dua thaum qhov kub txog 30-40 ° C. Cov dej ruaj khov txawm tias qhov kub thiab txias rau 48 teev.
⑤ Zoo solubility: nyob rau hauv chav tsev kub, ntxiv dej thiab do li 5 feeb, cia nws zaum ob peb feeb, thiab ces do kom dissolve. Kev tawg yog nrawm ntawm PH8-10. Cov tshuaj tau muab tso rau lub sijhawm ntev thiab muaj kev ruaj ntseg zoo. Hauv cov khoom sib xyaw qhuav, qhov ceev ntawm dispersing thiab dissolving hauv dej yog qhov zoo tshaj plaws.

Lub luag hauj lwm ntawm HPMC nyob rau hauv qhuav hmoov mortar

Nyob rau hauv qhuav hmoov mortar, methyl cellulose ether plays lub luag hauj lwm ntawm dej tuav, thickening thiab txhim kho kev tsim kho kev ua tau zoo. Kev tuav dej zoo ua kom ntseeg tau tias cov mortar yuav tsis ua rau cov xuab zeb, hmoov av thiab lub zog txo vim dej tsis txaus thiab tsis tiav cov cement hydration; Cov nyhuv thickening zoo heev txhim kho lub zog ntawm cov mortar ntub dej, thiab qhov sib ntxiv ntawm methyl cellulose ether tuaj yeem pom tseeb txhim kho cov viscosity ntawm cov khib nyiab ntub dej, thiab muaj qhov zoo adhesion rau ntau yam substrates, yog li kev txhim kho kev ua haujlwm ntawm cov ntaub ntub dej ntawm cov phab ntsa thiab txo qhov kev ua haujlwm zoo. pov tseg.

Feem ntau hais lus, qhov siab dua qhov viscosity, qhov zoo dua cov dej tuav. Txawm li cas los xij, qhov siab dua qhov viscosity, qhov siab dua qhov hnyav molecular ntawm MC, thiab nws cov solubility yuav raug txo qis, uas tuaj yeem cuam tshuam tsis zoo rau lub zog thiab kev tsim kho ntawm mortar. Qhov siab dua qhov viscosity, qhov pom tseeb dua cov nyhuv thickening ntawm mortar, tab sis nws tsis ncaj qha proportional. Qhov siab dua qhov viscosity, qhov viscous ntau dua cov mortar ntub yuav. Thaum lub sij hawm tsim kho, nws yog manifested raws li sticking rau lub scraper thiab siab adhesion rau lub substrate. Tab sis nws tsis muaj txiaj ntsig los ua kom lub zog muaj zog ntawm cov mortar ntub nws tus kheej.

Lub cev thiab tshuaj muaj zog:

1. Cov tsos: cov hmoov dawb los yog dawb dawb.
2. Particle loj: 80-100 mesh pass tus nqi yog ntau dua 98.5%; 80 mesh pass tus nqi yog 100%.
3. Carbonization kub: 280-300 ° C
4. Pom tseeb qhov ceev: 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. Discoloration kub: 190-200 ° C.
6. Nto nro: 2% aqueous tov yog 42-56dyn / cm3.
7. Soluble hauv dej thiab qee cov kuab tshuaj, xws li ethanol / dej, propanol / dej, trichloroethane, thiab lwm yam. Cov kev daws teeb meem dej yog qhov chaw ua haujlwm. High transparency thiab ruaj khov ua haujlwm. Cov khoom sib txawv ntawm cov khoom muaj qhov sib txawv gel kub, thiab cov solubility hloov nrog viscosity. Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility. Kev sib txawv ntawm HPMC muaj qee qhov sib txawv hauv kev ua haujlwm, thiab kev sib cais ntawm HPMC hauv dej tsis cuam tshuam los ntawm tus nqi pH.
8. Nrog rau kev txo qis ntawm cov ntsiab lus methoxyl, cov ntsiab lus gel nce, cov dej solubility ntawm HPMC txo qis, thiab cov dej ua haujlwm saum npoo kuj txo.
9. HPMC kuj muaj cov yam ntxwv ntawm thickening peev xwm, ntsev tsis kam, tsis tshua muaj tshauv cov ntsiab lus, PH stability, dej tuav, seem stability, zoo heev zaj duab xis tsim, thiab ntau yam enzyme kuj, dispersibility thiab cohesiveness.

Lub hom phiaj tseem ceeb:

1. Kev tsim kho kev lag luam: Raws li tus neeg saib xyuas dej-retaining thiab retarder rau cov cement mortar, nws tuaj yeem ua rau cov mortar twj tso kua mis. Siv los ua cov ntaub ntawv hauv plaster, plaster, putty hmoov lossis lwm yam khoom siv hauv tsev los txhim kho kev sib kis thiab ua haujlwm ntev. Nws tuaj yeem siv los ua cov nplais pobzeb, marble, kho kom zoo nkauj yas, muab tshuaj ntxiv, thiab tuaj yeem txo cov cement. Kev ua haujlwm ntawm cov dej khaws cia ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening.
