Hydroxypropyl methyl cellulose

Hydroxypropyl methyl cellulose (HPMC) yog cov khoom siv polymer ntuj los ntawm kev ua cov tshuaj lom neeg thiab kev npaj cov non-ionic cellulose ether.
DB series HPMC yog cov khoom hloov kho cellulose ether uas yaj tau ntau dua hauv dej thiab tsim tshwj xeeb rau kev txhim kho kev ua tau zoo ntawm cov tshuaj mortar qhuav tom qab kev kho saum npoo.

Cov yam ntxwv ntawm cov khoom: ☆ Ua kom muaj dej ntau ntxiv
Kev khaws dej siab, ua kom lub sijhawm ua haujlwm ntawm cov khoom siv ntev dua, txhim kho kev ua tau zoo, zam kev tshwm sim ntawm cov kab nrib pleb, thiab pab txhim kho lub zog kho tshuab ntawm cov khoom siv.
Txhim kho kev ua haujlwm zoo, muab cov roj nplua nyeem thiab cov qauv sib xws, ua rau cov khoom siv yooj yim dua los so, yog li txhim kho kev tsim kho kom zoo, thiab txhim kho kev tiv thaiv kev tawg ntawm putty.
Txhim kho qhov sib npaug, thiab txhim kho kev ua haujlwm tiv thaiv kev qaug zog

Cov khoom ib txwm muaj: Gel kub: 70 ℃ -91 ℃
Cov dej noo: ≤8.0%
Cov ntsiab lus tshauv: ≤3.0%
Tus nqi PH: 7-8
Qhov viscosity ntawm cov kua muaj feem cuam tshuam nrog qhov kub thiab txias. Thaum qhov kub ntawm cov kua nce ntxiv, qhov viscosity pib txo qis kom txog thaum cov gel tsim, thiab qhov kub thiab txias nce ntxiv yuav ua rau muaj flocculation. Cov txheej txheem no rov qab tau.

Qhov kev sib raug zoo ntawm viscosity thiab kev khaws dej, qhov viscosity siab dua, qhov kev khaws dej zoo dua. Feem ntau, lub peev xwm tuav dej ntawm cellulose hloov pauv raws li qhov kub thiab txias, thiab qhov nce ntawm qhov kub yuav ua rau lub peev xwm tuav dej txo qis.
DB series hloov kho cellulose ether: los ua kom zoo dua qhov kev ua tau zoo ntawm lub kaw lus rwb thaiv tsev sab nraud hauv lub caij ntuj sov kub siab ib puag ncig
Kev ncua sijhawm tsim kho
Lub sijhawm airing tau ntev dua
Kev ua haujlwm zoo heev
Kev tawg yog txo qis heev
Cov slurry muaj kev ruaj khov zoo
DB series hloov kho cellulose ether: los ua kom zoo dua qhov kev ua tau zoo ntawm phab ntsa sab nraud putty hauv qhov kub thiab txias siab thaum lub caij ntuj sov
Kev ncua sijhawm tsim kho
Lub sijhawm khawb tau ntev dua
Kev ua haujlwm zoo heev
Cov slurry muaj kev ruaj khov zoo

Daim ntawv thov khoom: Hauv kev tsim kho vaj tse, nws tuaj yeem muab cov khoom siv zoo heev rau kev tsim kho thiab khaws dej rau cov tshuab shotcrete thiab cov tshuaj pleev tes ua, cov tshuaj nplaum rau phab ntsa qhuav, cov kua nplaum rau cov vuas ceramic thiab cov tshuaj nplaum hooking, cov tshuaj pleev extruded, cov pob zeb hauv qab dej, thiab lwm yam. Hais txog cov nplaum, qhov sib xws ntawm cov nplaum thiab cov nplaum tuaj yeem ua rau ntau dua thiab ua rau muaj zaj duab xis hauv cov nplaum dispersion. Cov txheej txheej tuaj yeem siv ua cov tshuaj nplaum tuab, cov tshuaj tiv thaiv colloid, cov tshuaj pleev xim, kom txhim kho qhov viscosity ntawm cov txheej txheej dej stabilizer thiab solubility; Nws tuaj yeem ua rau cov dej khaws cia thiab lubrication hauv cov txheej txheem ntawm cov khoom siv ceramic.
