Hydroxypropylmethylcellulose (HPMC) chinhu chakakosha uye chinoshandiswa zvakasiyana-siyana chinoshandiswa mumaindasitiri mazhinji kusanganisira plaster range.HPMC is a cellulose ether inotorwa kubva muselulosi uye haina nonionic, inonyungudika nemvura polima.Inowanzoshandiswa seyakakora, stabilizer uye emulsifier mumisika yemvura uye yakaoma.Muindasitiri yegypsum, HPMC inoshandiswa se dispersant uye thickener.Ichi chinyorwa chinotsanangura mabhenefiti ekushandisa HPMC mukugadzira gypsum.
Gypsum chicherwa chinongoitika chinowanzo shandiswa muindasitiri yekuvaka kugadzira simende negypsum.Kuti ugadzire zvigadzirwa zvegypsum, gypsum inofanira kutanga yagadziriswa kuita fomu yehupfu.Nzira yekugadzira gypsum powder inosanganisira kupwanya uye kugaya mineral, wozoipisa pakupisa kwakanyanya kubvisa mvura yakawandisa.Hupfu hwakaoma hunozobuda hunobva hwasanganiswa nemvura kuti huite paste kana slurry.
Chimwe chezvinhu zvakakosha zveHPMC muindasitiri yegypsum ndiko kugona kwayo kwekuparadzira.Muzvigadzirwa zvegypsum, HPMC inoita seanoparadzira, ichipwanya zvidimbu zvezvimedu uye nekuona kugovera kwavo yunifomu mukati mese slurry.Izvi zvinoita kuti pave nekunamira kwakapfava, kunoenderana-siyana izvo zviri nyore kushanda nazvo.
Pamusoro pekuva dispersant, HPMC zvakare inokora.Inobatsira kuwedzera viscosity yegypsum slurry, zvichiita kuti zvive nyore kubata nekushandisa.Izvi zvinonyanya kukosha kune zvigadzirwa zvinoda kusimba kwakasimba, senge majoini emubatanidzwa kana plaster.
Imwe bhenefiti yakakosha yeHPMC muindasitiri yegypsum ndeyekuvandudzika kwayo kushanda.Kuwedzera HPMC kune gypsum slurries kunoita kuti chigadzirwa chipararire nyore uye chishande kwenguva refu.Izvi zvinoreva kuti makondirakiti uye vanhu vane nguva yakawanda yekushanda pachigadzirwa chisati chagadzika.
HPMC zvakare inovandudza kunaka uye kusimba kwechigadzirwa chekupedzisira.Nekuita seanoparadzira, HPMC inova nechokwadi chekuti gypsum zvimedu zvakagovaniswa zvakaenzana muchigadzirwa.Izvi zvinoita kuti chigadzirwa chiwedzere kusimba, chinowirirana uye chisinganyanyi kuputika uye kuputsa.
HPMC chinhu chinobatsira zvakatipoteredza.Haina chepfu, biodegradable uye haikonzeri kusvibiswa kwemhepo.Izvi zvinoita kuti ive sarudzo yakanaka kune maindasitiri ane hanya nekukanganisa kwezvakatipoteredza kwezvigadzirwa zvavo.
HPMC chinhu chakakosha mumhuri yegypsum ine akawanda mabhenefiti.Kugona kwayo kuparadzira, kukora, kunatsiridza processability uye kupera kwemhando yechigadzirwa kwakaita kuti ive chikamu chakakosha cheindasitiri.Hushamwari hwayo kwezvakatipoteredza zvakare ibhenefiti inocherekedza munyika umo maindasitiri mazhinji ari kutarisa kudzikisa maitiro avo ezvakatipoteredza.
