Chii chinonzi Foam Concrete?
Foamed kongiri rudzi rutsva rwezvinhu zvinochengetedza simba uye zvine hushamwari kwezvakatipoteredza zvine huwandu hukuru hweakavharika akavharwa pores, akareruka, anodzivirira kupisa, hunyoro-uchapupu uye inonzwika, uye inonyanya kukodzera kune ekunze madziro ekudzivirira masisitimu. zvezvivakwa. Zvinogona kuonekwa kubva pano kuti kuitira kuti udzikise zvinhu zvakasiyana-siyana zvefoam concrete, zvinyorwa zvayo zvinofanira kuva nezvinhu izvi. Nokudaro, sechinhu chinonyanya kukosha chekrete ye foam, hydroxypropyl methylcellulose inzvimbo yekuvaka ine mvura yakawanda yekuchengetedza, kupisa kwekushisa kwepamusoro uye kunamatira kwakasimba.
Nei hydroxypropyl methylcellulose ichiwedzerwa kune furo kongiri:
Nezve tekinoroji yekugadzira iripo, mapores mazhinji akavharwa mukongiri yefoam haapo neakasikwa, asi anogadzirwa nekuisa zvigadzirwa zvakaita sehydroxypropyl methylcellulose mumidziyo yekusanganisa uye nekuzvisanganisa kwenguva yakareba. Iri rudzi rwemapores akavharwa zvinogadzirisa zvinogadzirisa chiitiko chekuwandisa kwemarara ekuzadza uye kuchengetedza mari kusvika pamwero mukuru. Vamwe vanhu vanozobvunza kana pasina mhedzisiro yakadaro pasina kuwedzera hydroxypropyl methylcellulose? Ndinogona kukuudza chokwadi, hongu. Nekuda kwehunhu hwakakosha hwehydroxypropyl methylcellulose, inogona kuita kuti zvinhu zvakasiyana siyana zvibatane pamwe chete zvakanaka, kuitira kuti simba rakabatana rigone kugadzirwa pakati pavo, uye kusimba kwayo uye kupikisa kwekuwedzera kunogona kuwedzera.
