Cellulose Ether HPMC Siv Qib rau Phab Ntsa Putties

Cellulose ether HPMC (Hydroxypropylmethylcellulose) feem ntau yog siv los ua ib qho tseem ceeb additive hauv phab ntsa putty formulations. Phab ntsa putty yog cov khoom siv cementitious siv rau cov phab ntsa sab hauv thiab sab nrauv los muab cov du, txawm tias nto rau xim lossis phab ntsa. HPMC txhim kho ntau yam khoom ntawm phab ntsa putty, pab txhim kho nws cov kev ua tau zoo thiab cov yam ntxwv ntawm daim ntawv thov. Nov yog qee lub luag haujlwm tseem ceeb HPMC ua si hauv qib architectural phab ntsa putties:

Kev tuav dej: HPMC ua raws li tus neeg saib xyuas dej thiab pab tswj cov dej noo nyob rau hauv putty thaum lub sij hawm kho. Nws tiv thaiv kom qhuav sai thiab ua kom muaj dej txaus ntawm cov cement, txhawb kev kho kom zoo thiab txhim kho lub zog.

Kev ua haujlwm thiab kev sib kis tau: HPMC txhim kho kev ua haujlwm thiab kev sib kis ntawm phab ntsa putty, ua kom yooj yim sib xyaw, thov thiab sib kis ntawm qhov chaw. Nws imparts ib tug creamy sib xws thiab txhim kho cov ndlwg ntawm cov khoom, ua kom yooj yim daim ntawv thov thiab txo lub dag zog yuav tsum tau thaum lub sij hawm troweling.

Adhesion: HPMC txhim kho cov adhesion ntawm phab ntsa putties rau ntau yam substrates xws li pob zeb, plaster los yog masonry nto. Nws txhim kho daim ntawv cog lus lub zog thiab txo qhov yuav tshwm sim ntawm delamination lossis tev tawm lub sijhawm.

Crack resistance: Qhov sib ntxiv ntawm HPMC pab txhim kho qhov tawg tsis kam ntawm phab ntsa putty. Nws txo qis shrinkage thiab txo qis kev tawg vim yog ziab lossis thermal txav. Cov cuab yeej no txhim khu lub putty lub durability thiab pab tswj lub seamless nto.

Sag Resistance: HPMC pab txhawb rau sag kuj ntawm phab ntsa putties thaum siv rau ntsug nto. Nws pab lub putty khaws nws cov duab thiab tiv thaiv ntau deformation los yog tawg thaum lub sij hawm tsim kho, kom ntseeg tau tias ib tug txawm phab ntsa thickness.

Lub Sijhawm Qhib: HPMC txuas ntxiv lub sijhawm qhib ntawm phab ntsa putty, uas yog hais txog lub sijhawm cov khoom siv tseem siv tau tom qab sib xyaw. Nws tso cai rau lub qhov rais daim ntawv thov ntev dua thiab tshwj xeeb tshaj yog muaj txiaj ntsig zoo thaum ua haujlwm hauv thaj chaw loj dua lossis nyob rau hauv qhov kub thiab txias.

Tus nqi pes tsawg ntawm HPMC siv rau hauv phab ntsa putty yog nyob ntawm cov yam ntxwv xws li qhov xav tau sib xws, ib puag ncig thiab cov khoom tsim tshwj xeeb. Cov neeg tsim khoom ntawm qib architectural HPMC feem ntau muab cov lus qhia thiab cov lus pom zoo rau kev koom ua ke rau hauv phab ntsa putty systems. Nws raug nquahu kom sim ua raws li cov chaw tsim khoom cov lus qhia kom ua tiav qhov kev ua tau zoo thiab qhov zoo ntawm phab ntsa putty.
