Hydroxypropyl methylcellulose (HPMC) yog ib tug nonionic cellulose ether npaj los ntawm ib tug series ntawm tshuaj ua siv tej yam ntuj tso polymer khoom cellulose ua raw khoom. Lawv yog cov tsis muaj ntxhiab tsw, tsis muaj ntxhiab, tsis muaj tshuaj lom cov hmoov dawb uas swells hauv dej txias rau hauv cov kua ntshiab lossis me ntsis turbid colloidal. Nws muaj cov yam ntxwv ntawm thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, deg kev ua si, noo noo retention thiab tiv thaiv colloid. Hydroxypropyl methylcellulose, methyl cellulose tuaj yeem siv rau hauv kev tsim khoom, txheej txheej kev lag luam, hluavtaws cob, ceramic kev lag luam, tshuaj, khoom noj khoom haus, textile, kev ua liaj ua teb, tshuaj niaj hnub thiab lwm yam lag luam.
Hydroxypropyl methylcellulose (HPMC) Tshuaj sib npaug:

(3) Tswj cov kev taw qhia ntawm huab cua kom tshem tawm cov kab nrib pleb ntawm cov txheej txheej los ua kom lub ntsej muag du.
2. Gypsum-based plaster thiab gypsum khoom
(1) Txhim kho qhov sib xws, ua kom plaster yooj yim rau smear, txhim kho sag kuj, txhim khu fluidity thiab pumpability, thiab txhim kho kev ua hauj lwm efficiency.
(2) Kev tuav dej siab, ua kom lub sijhawm tso rau ntawm lub mortar, txhim kho kev ua haujlwm zoo, thiab ua kom lub zog siab ntawm cov mortar hydration thiab solidification.
(3) Tswj qhov sib xws ntawm qhov sib xws ntawm mortar los tsim cov txheej txheej uas xav tau.
3. Masonry mortar
(1) Txhim kho qhov adhesion rau ntawm qhov chaw masonry, txhim khu kev tuav dej, thiab ua kom lub zog ntawm cov mortar.
(2) Txhim kho lubricity thiab plasticity, txhim kho kev ua haujlwm; siv mortar txhim kho los ntawm cellulose ether, uas yooj yim rau kev tsim, txuag lub sij hawm tsim kho thiab txo cov nqi tsim kho.
(3) Ntxiv dej tuav cellulose ether rau siab nqus dej cib.
4. Kev sib koom ua ke
(1) Kev tuav dej zoo heev, qhib lub sijhawm qhib thiab txhim kho kev ua haujlwm zoo. Highly lubricated thiab yooj yim rau mix. (2) Txhim kho qhov shrinkage kuj thiab tawg tsis kam thiab txhim kho qhov zoo ntawm txheej txheej. (3) Txhim kho qhov adhesion ntawm qhov chaw sib txuas kom ua kom zoo nkauj, du.
5. Pobzeb Adhesive
(1) Nws yog ib qho yooj yim kom qhuav cov khoom xyaw, tsis muaj clumps, txhim kho daim ntawv thov ceev, txhim kho kev tsim kho, txuag lub sijhawm ua haujlwm thiab txo nqi ua haujlwm.
(2) Txhim kho qhov ua tau zoo ntawm cov nplais los ntawm kev ncua lub sijhawm qhib thiab muab cov adhesion zoo heev.
6. Cov khoom siv hauv pem teb nws tus kheej
(1) Muab viscosity thiab ua raws li kev tiv thaiv kev daws teeb meem. (2) Txhim kho lub twj tso kua mis ntawm fluidity thiab txhim kho kev ua haujlwm ntawm paving hauv av. (3) Tswj dej tuav thiab shrinkage, txo qhov tawg thiab shrinkage nyob rau hauv av.
7. Cov xim pleev xim rau dej
(1) Tiv thaiv kom tsis txhob muaj nag lossis daus thiab ua kom lub sijhawm ntim ntawm cov khoom. High biostability nrog zoo heev compatibility nrog rau lwm yam Cheebtsam. (2) Txhim kho fluidity, muab zoo spatter kuj, sag kuj thiab leveling kom paub meej zoo nto tiav.
8. Wallpaper hmoov
(1) Yooj yim yaj tsis muaj clumps, uas yog qhov zoo rau kev sib tov. (2) Ua kom muaj kev ruaj ntseg zoo.
9. Extruded cement ntawv
(1) Nws muaj siab cohesiveness thiab lubrication thiab txhim khu kev ua tau zoo ntawm cov khoom extruded. (2) Txhim kho ntsuab lub zog, txhawb hydration curing nyhuv, thiab txhim kho yield.
10. Npaj-tso mortar
HPMC cov khoom rau cov khoom sib xyaw ua ke yog zoo dua li cov khoom siv hauv cov khoom sib xyaw ua ke, kom ntseeg tau tias cov khoom siv cementing tsis muaj dej txaus, tiv thaiv kom tsis txhob muaj zog ntawm daim ntawv cog lus los ntawm kev ziab ntau dhau, thiab tawg los ntawm kev ziab shrinkage. HPMC kuj muaj qee qhov kev ua pa. HPMC cov khoom rau premixed mortar muaj ib tug zoo npaum li cas ntawm venting, uniformity thiab me npuas, uas yuav txhim khu lub zog thiab smearing ntawm npaj txhij-siv mortar. HPMC cov khoom siv tshwj xeeb uas siv rau cov khoom sib xyaw ua ke muaj qee yam kev cuam tshuam, uas tuaj yeem txuas ntxiv lub sijhawm qhib ntawm cov mortar npaj txhij thiab txo qhov nyuaj ntawm kev tsim kho.
