HydroxyPropyyl methylcellose (HPMC) yog cov tsis-ionic cellulose ither ua los ntawm cov txheej txheem polymer los ntawm cov txheej txheem polymer los ntawm cov txheej txheem polymer los ntawm cov txheej txheem ntawm cov txheej txheem. Lawv yog cov ntxhiab tsw, tsis muaj qab hau thiab cov hmoov dawb dawb uas swed mus rau hauv qhov tseeb lossis me ntsis pos huab colloidal tov hauv dej txias. Nws muaj thickening, khi, dispersing, ua yeeb yaj kiab, ua yeeb yaj kiab, kev tshaj tawm, kev ua kom nto, khaws cia thiab tiv thaiv kev tiv thaiv thiab tiv thaiv kev tiv thaiv kab mob. Hydroxypropy thiab methylcellulose tuaj yeem siv rau hauv cov ntaub ntawv tsim tsev, tshuaj, khoom noj khoom haus, ua liaj ua teb, kev ua liaj ua teb txhua hnub thiab lwm yam kev lag luam.

2. Gypsum-raws li plaster thiab gypsum khoom
⑴ Txhim kho cov kev sib tw, ua cov plastering yooj yim dua mus trowel, txhim kho kev ua haujlwm, txhim kho fwscegent tsis kam, txhim kho fwscarity thiab kev tso nyiaj, thiab txhim kho kev ua haujlwm tau zoo.
Cov dej nplua zog siab, ntev ntev lub sijhawm cug, txhim kho kev ua haujlwm, thiab ua kom haum rau cov dej khib nyiab kom muaj cov tshuab muaj zog.
⑶ Tswj cov kev sib khib ntawm cug ua kom muaj cov txheej txheem zoo tshaj plaws saum npoo.
3. Masonry tshuaj khib
⑴ Pab txhim kho cov nplaum nrog cov masonry nto, txhim kho cov dej khaws cia, thiab txhim kho lub zog ntawm lub tshuaj khib.
⑵ Txhim kho lubricity thiab cov yas, thiab txhim kho kev tsim kho; Lub capulose txhim kho los ntawm cellulose ether yog qhov yooj yim los tsim, txuag sijhawm kev tsim kho thiab txo tus nqi tsim khoom.
⑶ ultra-siab dej-khaws cia cellulose ether, haum rau cov dej-dej-nqus cov cib.
4. Vaj huam sib luag sib koom tes ua ke
Dej tsis ua haujlwm, ntev ntev lub sijhawm qhib thiab txhim kho kev ua haujlwm efficiency. Siab roj nplua nyeem, yooj yim dua los sib tov. ⑵ Txhim kho cov shrinkage tsis kam thiab tawg tsis kam, txhim kho cov txheej xim zoo. ⑶ Txhim kho cov nplaum ntawm txoj kev sib raug zoo thiab muab cov qauv du thiab du.
5. ⑵ Los ntawm lub sijhawm ntev qhib lub sijhawm qhib, kev ua haujlwm ntawm cov tiling tuaj yeem hloov kho thiab cov nplaum adhesion zoo tuaj yeem muab tau.
6. Kev ua tus kheej theem pem teb ⑴ Muab viscosity thiab tuaj yeem siv los ua cov tshuaj tiv thaiv sedimentation. ⑵THANCE LUB LAG LUAM NTAWM FLUE NTAWM FLU thiab txhim kho kev ua haujlwm ntawm paving hauv av. ⑶ Tswj dej khaws cia thiab shrinkage, txo cov kab nrib pleb thiab shrinkage ntawm hauv av.
7. Dej-ua xim pleev xim ⑴prevent stishitation nag thiab prolong lub thawv ua haujlwm ntawm cov khoom. Muaj kev ruaj khov muaj kuab, zoo sib xws nrog lwm cov khoom. • Txhim kho cov flui-flui-txaws, tiv thaiv cov yam ntxwv, thiab paub meej tias nto nto li tiav.
8. Phab ntsa hmoov ⑴ yaj sai uas tsis muaj lumps, uas yog qhov zoo rau kev sib xyaw. ⑵ Muab lub zog ua kom muaj zog.
9. Extruded Mement Board (1) muaj cohesenive thiab lub zog loj, thiab txhim kho cov khoom siv ntawm cov khoom seem. ⑵ Txhim kho lub zog ntsuab, txhawb nqa cov dej num thiab kho cov nyhuv, thiab nce tawm los.
10. HPMC cov khoom lag luam kom npaj ua cov khoom siv HPMC kom npaj tau cov khoom sib xyaw zoo dua qub, ua kom pom kev txo qis ntawm cov nyiaj sib xyaw ua rau kom qhuav , thiab cov kab nrib pleb tshwm sim los ntawm kom qhuav shrinkage. HPMC kuj muaj qee cov nyhuv cua-nkag. HPMC cov khoom lag luam tshwj xeeb siv rau kev npaj ua kom zoo-sib xyaw ua ke, cov pa hluav taws xob uas tsim nyog txhim kho lub zog thiab txoj kev kho kom huv ntawm cov tshuaj khib nyiab. HPMC cov khoom lag luam tshwj xeeb siv rau kev npaj ua kom tiav-sib xyaw ua kom tiav lub sijhawm qhib-mixed kev tsim kho.
