HPMC siv hauv Aerated Concrete Blocks Laying Mortars

HPMC, los yog hydroxypropyl methylcellulose, feem ntau yog siv los ua ib qho additive nyob rau hauv zus tau tej cov aerated qhob blocks mortars. Aerated qhob blocks yog lub teeb yuag thiab ntxeem tau, ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev tsim kho cov haujlwm uas yuav tsum tau muaj kev rwb thaiv tsev thiab kev siv hluav taws xob.

Ib qho ntawm lub luag haujlwm tseem ceeb ntawm HPMC hauv aerated qhob blocks nteg mortars yog los ua cov 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 sawv cev nyob rau hauv aerated qhob blocks nteg mortars. Qhov sib ntxiv ntawm HPMC rau hauv mortar txhim kho nws txoj kev adhesion rau lub substrate, tsim kom muaj kev ruaj khov thiab ruaj khov. HPMC kuj tseem tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ntawm lub mortar, uas pab tiv thaiv nws ntawm huab cua thiab yaig.

Lwm qhov txiaj ntsig ntawm kev siv HPMC nyob rau hauv aerated qhob blocks nteg 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 yog ib qho teeb meem tshwm sim hauv aerated qhob blocks tso mortars.

HPMC tseem tuaj yeem txhim kho qhov ua haujlwm ntev thiab lub zog ntawm aerated qhob blocks tso mortars dhau 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 rau aerated qhob blocks tso mortars muab ntau yam txiaj ntsig, suav nrog kev txhim kho kev ua haujlwm, adhesion, thiab kav ntev. HPMC kuj tseem pab tiv thaiv cov mortar los ntawm huab cua thiab yaig, thiab tuaj yeem tiv thaiv kev tawg thiab shrinkage. Nws kuj yog ib qho khoom noj khoom haus zoo ib puag ncig, uas muaj txiaj ntsig zoo rau ob tus neeg siv thiab ib puag ncig.
