Cellulose ether, kunyanya Hydroxypropyl Methylcellulose (HPMC), chinhu chinowanzoshandiswa mukugadzira masonry uye plastering dhaka. Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha muindasitiri yekuvaka. Muchikamu chino, tichaongorora basa re cellulose ether mukusimudzira mashandiro uye kushanda kwedhaka.
Basa rekutanga re cellulose ether mune masonry uye plastering dhaka nderekuvandudza kushanda. HPMC inoshanda sechinhu chinochengeta mvura, ichiva nechokwadi chekuti dhaka rinochengetedza kuwirirana panguva yekushandiswa. Pasina cellulose ether, musanganiswa wacho waibva waoma, zvichiita kuti zviomere vashandi kuparadzira uye kuisa dhaka zvakaenzana. HPMC inobatsira kuwedzera nguva inoshanda yedhaka, ichibvumira kutevedzera zviri nani uye kuderedza kudiwa kwekudzokorora nguva nenguva.
Rimwe basa rakakosha re cellulose ether mudhaka kugona kwayo kuwedzera simba rebhondi. Kana yawedzerwa kumusanganiswa, HPMC inogadzira firimu rakatetepa rakatenderedza masimende masimende, ayo anonatsiridza kunamatira pakati pedhaka uye substrate. Iyi firimu inoshandawo semafuta, kuderedza kupesana pakati pezvikamu, uye kudzivirira kupatsanurwa panguva yekufambisa uye kushandiswa. Iyo yakagadziridzwa simba rebhondi rinopihwa ne cellulose ether inovimbisa kusimba uye kusimba kwekupedzisira chigadzirwa.
Cellulose ether inobatsirawo kukudzivirira kwemvura kwese kwemasonry uye plastering dhaka. Kuvapo kweHPMC kunobatsira kugadzira firimu rehydrophobic pamusoro pevhu, kudzivirira kupinda kwemvura uye kukuvadza kunotevera. Uku kuramba kwemvura kunonyanya kukosha mumashandisirwo ekunze uko dhaka rinosangana nemamiriro ekunze akaomarara. Nekudzikisa kunyura kwemvura, cellulose ether inobatsira kudzivirira kutsemuka, efflorescence, uye zvimwe zvine chekuita nehunyoro, zvichikonzera hupenyu hurefu hwekuvaka.
Cellulose ether inoita basa rakakosha mukudzora kuderera uye kuputika mudhaka. Kuwedzerwa kweHPMC kunobatsira kuderedza kuomeswa kwedhaka, iyo inowanzokonzera kuputika. Nekudzikisa shrinkage, cellulose ether inova nechokwadi chekuti chigadzirwa chakapedzwa chinoramba chakasimba. Zvakare, iyo mhezi inopikisa inopihwa neHPMC inosimudzira kusimba uye aesthetics, kudzivirira kudiwa kwekugadzirisa kunodhura kana kushandazve nekufamba kwenguva.
Mukupedzisa, cellulose ether, kunyanya Hydroxypropyl Methylcellulose (HPMC), inoita basa rakakosha mukugadzira uye kupurasita dhaka. Kugona kwayo kuvandudza kushanda, kuwedzera simba rechisungo, kupa mvura kuramba, uye kudzora shrinkage kunoita kuti ive yekuwedzera yakakosha muindasitiri yekuvaka. Nezvakawanda zvakanakira, cellulose ether inoita kuti dhaka rive nyore kushanda naro, rinogara, uye rinogara kwenguva refu. Vavaki nemakondirakiti vanogona kuvimba necellulose ether kuti vaunze mashandiro epamusoro uye kuwana mhedzisiro yemhando yepamusoro mumapurojekiti avo ekugadzira masonry uye plastering.
