Kev thov HPMC hauv cov khoom siv hauv tsev

Hydroxypropyl methylcellulose (HPMC)yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm tej yam ntuj tso polymer khoom cellulose los ntawm ib tug series ntawm tshuaj ua. Lawv yog cov tsis muaj ntxhiab tsw, tsis qab thiab tsis muaj kuab lom dawb hmoov uas swells hauv dej txias rau cov kua ntshiab lossis me ntsis hazy colloidal. Nws muaj cov yam ntxwv ntawm thickening, khi, dispersing, emulsifying, zaj duab xis-forming, suspending, adsorbing, gelling, deg zog, khaws cia noo noo thiab tiv thaiv colloids. Hydroxypropyl methylcellulose, methylcellulose tuaj yeem siv rau hauv cov khoom siv hauv tsev, txheej kev lag luam, hluavtaws cob, ceramics kev lag luam, tshuaj, khoom noj khoom haus, textile, kev ua liaj ua teb, tshuaj niaj hnub thiab lwm yam lag luam.

③ Tswj qhov sib xws ntawm cov tshuaj khib kom zoo ib yam thiab tsim cov txheej txheem zoo tagnrho.

3 Masonry mortar

① Txhim kho qhov adhesion nrog lub masonry nto, txhim khu cov dej tuav, thiab txhim kho lub zog ntawm cov mortar.

② Txhim kho lubricity thiab plasticity, thiab txhim kho kev ua haujlwm; lub mortar txhim kho los ntawm cellulose ether yog yooj yim rau kev tsim, txuag lub sij hawm tsim kho thiab txo cov nqi tsim kho.

③Ultra-high water-retaining cellulose ether, haum rau cov dej-absorbing cib.
4 phaj sib koom ua ke

① Cov dej tuav tau zoo, ncua sij hawm qhib thiab txhim kho kev ua haujlwm. High lubricant, yooj yim rau kev sib tov.

② Txhim kho shrinkage kuj thiab tawg tsis kam, thiab txhim kho qhov zoo ntawm cov txheej.

③ Txhim kho qhov adhesion ntawm qhov chaw sib txuas thiab muab kev ntxhib los mos thiab du.

5 Pobzeb Adhesives

① Yooj yim kom qhuav cov khoom xyaw, tsis muaj pob yuav raug tsim, daim ntawv thov ceev yuav nce, kev tsim kho yuav raug txhim kho, lub sijhawm ua haujlwm yuav raug cawm, thiab tus nqi ua haujlwm yuav raug txo.

② Los ntawm kev ncua lub sijhawm qhib, nws txhim kho kev ua haujlwm ntawm cov nplais thiab muab cov nyhuv adhesion zoo.

6 Self-leveling cov ntaub ntawv hauv pem teb

① Muab viscosity thiab siv tau los tiv thaiv kev daws teeb meem.

② Txhim kho lub twj tso kua mis ntawm fluidity thiab txhim kho kev ua haujlwm ntawm paving.

③ Tswj dej tuav thiab shrinkage kom txo tau cov kab nrib pleb thiab shrinkage ntawm av.

7 Cov xim pleev xim rau dej

① Tiv thaiv kom tsis txhob muaj nag lossis daus thiab ncua lub sijhawm ntim ntawm cov khoom. Siab lom ruaj ruaj thiab zoo heev compatibility nrog rau lwm yam Cheebtsam.

② Txhim kho fluidity, muab kev sib txhuam zoo, sag kuj thiab qib, thiab xyuas kom meej qhov zoo tshaj plaws.

8 wallpaper hmoov

① Ceev ceev yam tsis muaj agglomeration, uas yooj yim rau kev sib xyaw.

② Muab cov ntawv cog lus siab zog.

9 Extruded cement board

①Nws muaj adhesion siab thiab lubricity, thiab txhim kho cov txheej txheem ntawm cov khoom extruded.

② Txhim kho lub zog ntsuab, txhawb nqa dej thiab kho cov nyhuv, thiab txhim kho cov txiaj ntsig.

10 HPMC cov khoom lag luam rau cov khoom sib xyaw ua ke

CovHPMCCov khoom siv tshwj xeeb siv rau cov khoom sib xyaw ua ke muaj cov dej tuav tau zoo dua li cov khoom lag luam zoo tib yam hauv cov khoom sib xyaw ua ke, kom ntseeg tau tias cov khoom siv cementitious tsis muaj dej txaus, thiab tiv thaiv kom tsis txhob muaj zog ntawm daim ntawv cog lus los ntawm kev ziab thiab tawg ntau dhau los ntawm kev ziab shrinkage. HPMC kuj muaj qee yam huab cua nkag mus. HPMC cov khoom siv tshwj xeeb uas siv rau cov khoom sib xyaw ua ke muaj qhov tsim nyog, zoo ib yam thiab me me cua nkag, uas tuaj yeem txhim kho lub zog thiab plastering ntawm cov mortar npaj txhij. Cov khoom HPMC tshwj xeeb uas siv rau cov khoom sib xyaw ua ke muaj qee yam kev cuam tshuam, uas tuaj yeem ua rau lub sijhawm qhib ntawm cov khoom sib xyaw ua ke thiab txo qhov nyuaj ntawm kev tsim kho. Hydroxypropyl methylcellulose (HPMC) yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm cov khoom siv ntuj polymer cellulose los ntawm kev ua tshuaj lom neeg. Lawv yog cov tsis muaj ntxhiab tsw, tsis qab thiab tsis muaj kuab lom dawb hmoov uas swells hauv dej txias rau cov kua ntshiab lossis me ntsis hazy colloidal. Nws muaj cov yam ntxwv ntawm thickening, khi, dispersing, emulsifying, zaj duab xis-forming, suspending, adsorbing, gelling, deg zog, khaws cia noo noo thiab tiv thaiv colloids.
