Hydroxypropyl Methylcellulose (HPMC) yog ib qho kev siv ntau ntxiv hauv kev tsim kho kev lag luam. Nws yog non-ionic, dej-soluble cellulose ether uas yog muab los ntawm ntuj cellulose. HPMC yog cov khoom siv ntau yam polymer uas siv rau hauv ntau daim ntawv thov, suav nrog cov khoom siv. Hauv kab lus no, peb yuav tham txog kev siv HPMC hauv cov khoom siv.

1. Mortars thiab Plasters

HPMC feem ntau yog siv los ua thickener, binder, thiab dej-retaining tus neeg sawv cev hauv mortars thiab plasters. Nws txhim kho kev ua haujlwm, adhesion, thiab durability ntawm mortar lossis plaster. HPMC kuj txo qhov kev pheej hmoo ntawm kev tawg los ntawm kev txhim kho lub zog tensile ntawm cov tshuaj khib lossis plaster. Kev siv HPMC hauv mortars thiab plasters kuj txo cov dej uas xav tau, uas tuaj yeem ua rau lub sijhawm ziab sai dua thiab txo qis.

2. Pobzeb Adhesive

Cov nplaum nplaum yog siv los khi cov vuas rau ntau qhov chaw. HPMC feem ntau yog siv los ua cov thickener thiab cov dej tuav hauv cov nplais nplaum. Nws txhim kho lub sijhawm ua haujlwm thiab qhib lub sijhawm ntawm cov nplaum, uas tso cai rau cov vuas yuav raug kho ua ntej cov nplaum nplaum. HPMC kuj tseem txhim kho qhov adhesion ntawm cov nplaum rau cov substrate thiab cov pobzeb, uas txo qhov kev pheej hmoo ntawm pobzeb detachment.

3. Self-Leveling Compounds

Self-leveling compounds yog siv rau theem tsis sib xws los yog sloping pem teb. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining tus neeg sawv cev nyob rau hauv tus kheej-leveling compounds. Nws txhim kho cov dej ntws thiab qib qib ntawm cov khoom sib xyaw, uas tso cai rau nws sib kis tusyees thiab tsim ib qho chaw du. HPMC kuj txo qhov kev pheej hmoo ntawm kev tawg los ntawm kev txhim kho lub zog tensile ntawm cov compound.

4. Sab nrauv rwb thaiv tsev thiab Finishing Systems (EIFS)

EIFS yog ib hom ntawm sab nrauv phab ntsa cladding uas yog siv los muab cov rwb thaiv tsev thiab huab cua tiv thaiv rau cov tsev. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining agent hauv EIFS. Nws txhim kho kev ua haujlwm ntawm EIFS, uas tso cai rau nws siv tau yooj yim thiab sib npaug. HPMC kuj tseem txhim kho qhov adhesion ntawm EIFS rau lub substrate, uas txo qhov kev pheej hmoo ntawm detachment.

5. Cement-based Renderings

Cement-raws li renderings yog siv los muab kev kho kom zoo nkauj rau phab ntsa thiab lwm qhov chaw. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining agent hauv cement-based renderings. Nws txhim kho kev ua haujlwm ntawm kev ua haujlwm, uas tso cai rau nws siv tau yooj yim thiab sib npaug. HPMC kuj tseem txhim kho qhov adhesion ntawm rendering rau lub substrate, uas txo qhov kev pheej hmoo ntawm detachment.

6. Cov khoom siv gypsum

Gypsum-raws li cov khoom, xws li kev sib koom ua ke thiab plasters, yog siv los muab kev sib tw thiab seamless rau phab ntsa thiab qab nthab. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining agent hauv gypsum-based khoom. Nws txhim kho kev ua haujlwm ntawm cov khoom, uas tso cai rau nws siv tau yooj yim thiab sib npaug. HPMC kuj txhim kho qhov adhesion ntawm cov khoom mus rau lub substrate, uas txo qhov kev pheej hmoo ntawm detachment.

7. Cement-based Adhesives

Cement-raws li adhesives yog siv los khi ntau yam ntaub ntawv, xws li cov vuas, rau substrates. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining agent nyob rau hauv cement-raws li adhesives. Nws txhim kho kev ua haujlwm ntawm cov nplaum, uas tso cai rau nws siv tau yooj yim thiab sib npaug. HPMC kuj tseem txhim kho qhov adhesion ntawm cov nplaum rau lub substrate thiab cov khoom sib txuas, uas txo qhov kev pheej hmoo ntawm kev sib cais.

8. Txheej

Coatings, xws li cov xim thiab cov sealants, yog siv los tiv thaiv thiab kho kom zoo nkauj ntawm ntau qhov chaw. HPMC feem ntau yog siv los ua cov thickener thiab dej-retaining tus neeg sawv cev hauv txheej txheej. Nws txhim kho kev ua haujlwm thiab adhesion ntawm txheej, uas tso cai rau nws siv tau yooj yim thiab sib npaug. HPMC kuj tseem txhim kho qhov ua tau zoo ntawm cov txheej txheem los ntawm kev txo cov dej nqus dej thiab txhim kho kev tiv thaiv huab cua thiab puas.
