HPMC rau Kho Mortars

HPMC, los yog hydroxypropyl methylcellulose, yog ib qho khoom siv feem ntau siv hauv kev tsim cov tshuaj khib nyiab. Kev kho cov mortars yog siv los kho cov pob zeb puas lossis cov pob zeb, xws li phab ntsa, pem teb, thiab qab nthab.

Ib qho ntawm lub luag haujlwm tseem ceeb ntawm HPMC hauv kev kho cov mortars yog los ua lub thickener thiab rheology modifier. Qhov sib ntxiv ntawm HPMC rau hauv mortar txhim kho nws txoj kev ua haujlwm thiab kev sib kis, ua kom yooj yim rau kev thov thiab ua haujlwm nrog. HPMC kuj tseem txhim kho qhov sib xws thiab ruaj khov ntawm cov tshuaj khib nyiab, txo qhov kev pheej hmoo ntawm sagging lossis slumping thaum siv.

Ntxiv nrog rau nws cov khoom thickening, HPMC kuj ua raws li ib tug binder thiab film-forming tus neeg saib xyuas nyob rau hauv kho mortars. Qhov sib ntxiv ntawm HPMC rau hauv mortar txhim kho nws cov adhesion rau lub substrate, tsim kom muaj kev ruaj khov thiab ruaj khov. HPMC kuj tsim cov yeeb yaj kiab tiv thaiv rau ntawm qhov chaw ntawm lub mortar, uas pab tiv thaiv nws ntawm huab cua thiab yaig.

Lwm qhov txiaj ntsig ntawm kev siv HPMC hauv kev kho cov mortars yog tias nws tuaj yeem pab txhim kho cov mortar tiv thaiv kom tawg thiab shrinkage. HPMC tuaj yeem tuav dej hauv mortar, uas yuav pab kom nws ntub thiab tiv thaiv kom tsis txhob qhuav sai heev. Qhov no tuaj yeem pab tiv thaiv kev tawg thiab shrinkage, uas tuaj yeem ua teeb meem tshwm sim hauv kev kho cov mortars.

HPMC kuj tseem tuaj yeem txhim kho cov kav ntev thiab lub zog ntawm kev kho cov mortars thaum lub sijhawm. Nws tuaj yeem txhim kho cov mortar tiv thaiv dej, tshuaj lom neeg, thiab kev puas tsuaj, uas tuaj yeem pab ua kom nws lub neej ua haujlwm ntev thiab txo qhov kev xav tau ntawm kev kho yav tom ntej.

Tsis tas li ntawd, HPMC yog lub ntuj tsim, tsim dua tshiab, thiab biodegradable polymer uas tau muab los ntawm cellulose, uas muaj ntau hauv cov nroj tsuag. Nws yog non-toxic thiab tsis tso cov tshuaj phem rau hauv ib puag ncig, ua rau nws ib puag ncig tus phooj ywg additive.

Zuag qhia tag nrho, qhov sib ntxiv ntawm HPMC los kho cov mortars muab ntau cov txiaj ntsig, suav nrog kev txhim kho kev ua haujlwm, adhesion, thiab kav ntev.
