Cellulose ether zvigadzirwa zvinoshandiswa zvakanyanya kuvandudza kushanda kwe hydraulic kuvaka zvinhu, senge gypsum uye simende. Mune gypsum uye simende-based madhaka, inovandudza kuchengetedza kwemvura, inorebesa kururamisa uye kuvhurika nguva, uye inoderedza kusagging.
1. Kuchengeta mvura
Cellulose ether inodzivirira mwando kupinda mumadziro. Huwandu hwakakodzera hwemvura hunogara mudhaka, kuitira kuti gypsum nesamende zvive nenguva yakareba yekunyorova. Kuchengetedzwa kwemvura kwakanyatso kuenzana neiyo viscosity ye cellulose ether mhinduro mudhaka. Iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Kana iyo mwando inowedzera, kuchengetwa kwemvura kunoderera. Nokuti nokuda kwechiyero chakafanana che cellulose ether solution, kuwedzera kwemvura kunoreva kuderera kwe viscosity. Kuvandudzwa kwekuchengetedza mvura kuchaita kuti kuwedzerwa kwenguva yekuporesa kwedhaka riri kuvakwa.
2. Deredza viscosity uye kuvandudza kushanda
Iyo yakaderera viscosity ye cellulose ether inoshandiswa, iyo yakaderera viscosity yedhaka uye nekudaro zvirinani kushanda. Nekudaro, yakaderera viscosity cellulose ether ine yakakwira dosage nekuda kwekuderera kwayo kwemvura kuchengetedza.
3. Anti-sagging
Doka rakanaka risingapindi muvhu zvinoreva kuti dhaka rakaiswa mumitsetse yakakora harina njodzi yekurembera kana kuyerera ichidzika. Sag kuramba inogona kuvandudzwa ne cellulose. Cellulose ether inogona kupa zvirinani sag resistance yedhaka.
4. Bubble content
Yakakwira mhepo bubble yemukati inoburitsa zvirinani goho redhaka uye kushanda, kuderedza kutsemuka kuumbwa. Iyo inoderedzawo kukosha kwekusimba, zvichiita kuti "liquefaction" chiitiko. Mhepo bubble zvemukati zvinowanzoenderana nekukurudzira nguva.
