HydroxyPropyl methylcellose (HPMC) ndiyo kiyi inokosha mune yakaoma musanganiswa motsi mafambiro uye inopa basa rakakosha mukuwedzera zvinhu zvakasiyana-siyana zvechigadzirwa chekupedzisira chechigadzirwa chekupedzisira. Iyi polymer inoshandiswa zvakanyanya pakuvaka mabhuku ekuvaka nekuda kwekugona kwayo kuvandudza basa, kudenha, kuita kwemvura uye kusakwana kwemauto uye zvimwe zvinhu zvekushandisa.
1. Nhanganyaya kuHPMC:
Hydroxypropylmethylsellose inzvimbo yekushongedza, manyorerwo-emvura anodzika kubva kuCellulose, polymer yakasikwa inowanikwa mumasango masero emadziro. Kugadziridzwa kunosanganisira kuiswa kwehydroxyprupyl uye methyl mapoka mu cellulose backbone. Uku kugadziridzwa kunowedzera simba rekuita mvura, kugadzikana uye rateological zvivakwa zve polymer.
2. Hunhu hweHPMC:
Chemical chimiro: Chemical chimiro cheHPMC chine zvikamu zvekudzokorora zveGlucose mamorekuru vakabatanidzwa neHydroxyprosl uye methyl mapoka. Ichi chimiro chakasarudzika chinopa HPMC chaiyo gadziriro inokanda mitsipa yakaoma musanganiswa mongororo.
Solubl Solubility: HPMC inochema mumvura, inogadzira mhinduro yakajeka, isina ruvara. Iyi pfuma inozvitendera kuti ibatanidzwe nyore nyore kuita mongororo yekumanikidza kusimudzira kunyange kugovera.
Kuumbwa Kwayo: HPMC ine yakanaka yekudzivirira, inoona kuti zvivakwa zvayo zvinoramba zvakaringana panguva yekugadzira uye kushandiswa kweyakaoma-musanganiswa merare.
Kuenderana: HPMC inoenderana nezvimwe zvinhu zvakasiyana siyana, kusanganisira simende, lime, plaster, uye dzakasiyana siyana, uye dzakasiyana siyana, ichiita sarudzo yakaita mongororo.
3. Basa reHPMC mune yakaoma yakavhenganiswa mongwe:
Kuchengeta mvura: Imwe yemabasa makuru eHPMC ndeyekuvandudza kuchengetwa kwemvura kwemutumbi. Nekugadzira firimu rakatetepa pane iyo svutugadzike pamusoro uye inosungira mamorekuru emvura, HPMC inoderedza kubuda kwemvura panguva yekurapa, kudzivirira nguva yekuomesa uye kuona hydration yeiyo yemasimendi.
Kuvandudza Kudzorera: HPMC zviito seRheology Modifier kuvandudza basa rekushanda rakaoma rakasanganiswa. Izvo zvine rudziro zviri nani kuna Sag, ichiita kuti duri rive nyore kushandisa uye kuderedza njodzi yekutsvedza kana kutsvedza.
Yakavandudzwa Dhezheni: Hpmc inovandudza mongwe kudenha kune akasiyana siyana eSubstrates. Izvi zvakakosha kuti uwane chisungo chakasimba uye chemberi pakati pehudyu uye chivakwa chivakwa.
Control Control: HPMC inobatsira kudzora kuenderana kwemusanganiswa wegomo, ichisanganisira kufanana uye kusununguka kwekushandisa.
4. Zvakanakira kushandisa HPMC mune yakaoma yakavhenganiswa dhaka:
Kuwedzeredza kuita: Kuwedzera kweHPMC kuoma kusanganisa motsi mafomu kunogadzirisa maitiro ekuita sekuwedzera kwesimba
Yakaderedzwa Shrinkage: Iyo yekuchengetedza mvura yeHPMC rubatsiro kuderedza kuderera mukati mekuporesa maitiro, nekudaro kuderedza mukana wekupwanya muchimiro chekupedzisira.
Yakawedzerwa nguva yekuvhura: HPMC inokwidza nguva yekuvhura yedhaka, nekudaro ichipinda nguva pakati pekushandisa uye kurongedza. Izvi zvinonyanya kubatsira mumapurojekiti ekuvaka ekuvaka.
Kuedza: HPMC iri kushandiswazve uye kunogona kushandiswa nemhando dzese dzeMhando dzakaomeswa musanganiswa, kusanganisira tiles inonamira, grouts, stucco uye kuzvimanikidza makomendi.
5. Kushandiswa kweHPMC mune yakaoma yakavhenganiswa moter.
Tile Aomair: HPMC inowanzo shandiswa mumatombo emagetsi ekuvandudza kushungurudzika, kushanda uye nekuchengetwa kwemvura.
Motoro anowedzera: HPMC yakakosha inowedzera muumbi mongororo inobatsira kuvandudza mashandiro ehudyu.
Gypsum: Mune gypsum mafomu, HPMC inosimudzira kushanda, kujaira uye kusimba kwekupedza, kwakasimba.
Kuzvimiririra mishonga: HPMC inoshandiswa mukuzvimiririra makomputa kuti uwane iyo inodiwa rateological zvivakwa zvekuparadzira nyore uye nekumwe.
6. Mhedziso:
HydroxyPropyl methylcellose (HPMC) inoita basa rakakosha mukuvandudza mashandiro uye kuita kwemufananidzo wakaoma musanganiswa. Yayo yakasarudzika yemakemikari chimiro, solubity yemvura, uye kuenderana nezvinhu zvakasiyana-siyana zvekuvakisa zvekuvaka zvinoita kuti isarudzo dzisinganzwisisike kune dzakasiyana siyana dzekushandisa. Sezvo indasitiri yekuvaka ichiramba ichishanduka, iyo inodiwa yekuita uye yekuchengetedza zvekuvakira zvinhu zvinogona kutyaira kuenderera mberi mukushandiswa kwePolymers yakadai seHPMC mune yakaoma-musanganiswa motsi mafomu ekugadzira. Kuenderera mberi nekutsvaga nekuvandudza munzvimbo ino pasina mubvunzo kunounza mhinduro dzakawanda uye dzinobudirira kumanetso ekuvaka okuvaka.
