Foam Concrete yog dab tsi?
Foamed pob zeb yog ib hom tshiab ntawm kev txuag hluav taws xob thiab ib puag ncig cov khoom siv hauv tsev uas muaj ntau qhov sib npaug sib npaug kaw qhov pores, yog lub teeb, kub-resistant, noo noo-pov thawj thiab suab-pov thawj, thiab tshwj xeeb tshaj yog haum rau sab nrauv phab ntsa rwb thaiv tsev. ntawm cov tsev. Nws tuaj yeem pom los ntawm qhov no tias txhawm rau txhawm rau qeeb ntau yam khoom ntawm cov pob zeb ua npuas ncauj, nws cov additives yuav tsum muaj cov khoom no. Yog li ntawd, raws li cov khoom tseem ceeb tshaj plaws ntawm cov pob zeb ua npuas ncauj, hydroxypropyl methylcellulose yog cov khoom siv hauv tsev nrog cov dej tuav, kub tsis kam thiab muaj zog adhesion.
Yog vim li cas hydroxypropyl methylcellulose ntxiv rau cov pob zeb ua npuas ncauj:
Raws li tam sim no cov cuab yeej tsim khoom lag luam muaj kev txhawj xeeb, ntau qhov chaw kaw hauv cov pob zeb ua npuas ncauj tsis muaj nyob hauv ib txwm muaj, tab sis yog tsim los ntawm kev muab cov khoom siv raw xws li hydroxypropyl methylcellulose rau hauv cov khoom sib tov thiab sib tov rau lub sijhawm ntev. Qhov zoo ntawm cov pores kaw no zoo daws qhov tshwm sim ntawm cov khoom pov tseg ntau dhau ntawm cov fillers thiab txuag nqi mus rau qhov loj. Qee tus neeg yuav nug yog tias tsis muaj qhov cuam tshuam zoo li no tsis ntxiv hydroxypropyl methylcellulose? Kuv tuaj yeem qhia rau koj paub tseeb, yog. Vim muaj cov khoom tshwj xeeb ntawm hydroxypropyl methylcellulose, nws tuaj yeem ua rau ntau yam khoom siv sib xyaw ua ke zoo, kom lub zog tshwj xeeb cohesive tuaj yeem tsim los ntawm lawv, thiab nws cov tensile thiab extrusion kuj tuaj yeem nce ntxiv.
