Hydroxypropyl Methyl Cellulose

1.Qhov tshwm sim: Dawb los yog tawm -dawb hmoov.
2. Particle loj: qhov dhau ntawm 100 mesh yog ntau dua 98.5%; qhov dhau ntawm 80 mesh yog 100%. Qhov loj me me ntawm cov lus tshwj xeeb yog 40-60 mesh.
3. Carbonization kub: 280 - 300 degree
4. Pom tseeb qhov ceev: 0.25 - 0.70 g/cm³ (feem ntau nyob ib ncig ntawm 0.5 g/cm³), lub ntiajteb txawj nqus: 1.26 - 1.31.
5. Xim-hloov kub: 190 - 200 degree
6. Nto nro: 42 - 56 dyn/cm rau 2% aqueous tov.
7. Solubility: Nws dissolves nyob rau hauv dej thiab ib co kuab tshuaj, xws li ethanol / dej thiab propanol / dej nyob rau hauv cov proportions tsim nyog. Cov tshuaj aqueous muaj qhov ua haujlwm saum npoo. Nws muaj cov pob tshab siab thiab kev ua haujlwm ruaj khov. Lub gelation kub sib txawv ntawm cov khoom sib txawv ntawm cov khoom. Lub solubility hloov nrog viscosity; Qhov qis dua qhov viscosity, ntau dua qhov solubility. Cov kev qhia tshwj xeeb sib txawv ntawm HPMC muaj qee qhov kev ua tau zoo sib txawv. Kev solubility ntawm HPMC hauv dej tsis cuam tshuam los ntawm tus nqi pH.

1. Kev tsim kho kev lag luam: Raws li cov dej- tuav tus neeg saib xyuas thiab rov qab rau cov cement mortar, nws ua rau cov mortar muaj cov twj tso kua mis. Nyob rau hauv plastering mortar, gypsum cov ntaub ntawv, putty hmoov los yog lwm yam ntaub ntawv hauv tsev, nws ua hauj lwm pab raws li ib tug binder, txhim kho cov txheej txheem thiab ncua sij hawm ua hauj lwm. Nws tuaj yeem siv los ua cov nplaum nplaum rau pobzeb, marble, kho kom zoo nkauj yas, thiab ua tus neeg sawv cev rau kev sib txuas, thiab nws tuaj yeem txo cov cement siv. Cov dej- khaws cov cuab yeej ntawm hydroxypropyl methylcellulose (HPMC) tiv thaiv cov txheej txheem ntawm kev tawg vim ziab sai sai tom qab thov thiab txhim kho lub zog tom qab hardening.
2. Ceramic manufacturing kev lag luam: Nws yog dav siv los ua ib txoj hlua khi hauv kev tsim cov khoom siv ceramic.
3. Coatings kev lag luam: Raws li ib tug thickener, dispersant thiab stabilizer nyob rau hauv lub coatings kev lag luam, nws muaj zoo solubility nyob rau hauv dej thiab organic solvents. Nws kuj tseem siv tau los ua xim stripper.
4. Ink printing: Hauv kev lag luam number case, nws ua hauj lwm raws li ib tug thickener, dispersant thiab stabilizer, thiab muaj zoo solubility nyob rau hauv dej thiab organic solvents.
5. Plastics: raws li molding tso tus neeg sawv cev, softeners, lubricants, thiab lwm yam.
6. Polyvinyl chloride: Hauv kev tsim cov polyvinyl chloride, nws ua hauj lwm raws li ib tug dispersant thiab yog ib tug loj additive nyob rau hauv lub ncua kev kawm ntawv polymerization txheej txheem rau kev npaj PVC.
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 textile industries, thiab lwm yam.
8. Kev lag luam tshuaj: txheej txheej; Cov ntaub ntawv membrane; Rate- tswj cov ntaub ntawv polymer rau kev ruaj ntseg- tso tawm kev npaj; Stabilizers; Cov neeg ua haujlwm raug ncua; Tablet binders; Thickening agents
