Hydroxypropyl methylcellulose (HPMC) yakasungirirwa gypsum

suma:

Hydroxypropyl methylcellulose (HPMC) yakasungirirwa gypsum chinhu chekucheka-kumucheto chivakwa chinosanganisa zvimiro zvehydroxypropyl methylcellulose uye gypsum.Uyu musanganiswa mutsva unoguma mune yepamusoro-inoshanda zvinhu zvine akawanda maapplication muindasitiri yekuvaka.

Hydroxypropyl methylcellulose (HPMC):

1.1.Tsanangudzo uye zvivakwa:

Hydroxypropyl methylcellulose, inowanzo zivikanwa seHPMC, is cellulose ether inotorwa kubva kune yakasikwa polymer cellulose.Yakanakisa kuchengetedza kwemvura, kukora uye firimu-kugadzira zvivakwa zvinoita kuti ive yakakurumbira yekuwedzera mumaindasitiri akasiyana siyana, kusanganisira kuvaka.HPMC inoratidzirwa nekunyungudika mumvura inopisa uye inotonhora, ichipa versatility mumashandisirwo akasiyana.

1.2.Basa mukuvaka:

Muindasitiri yekuvaka, HPMC inoshandiswa zvakanyanya sekuwedzera mune simende-yakavakirwa zvinhu, dhaka uye gypsum plasters.Kugona kwavo kubata mvura kunowedzera kushanda uye kunowedzera nguva yekugadzika kwezvinhu izvi.HPMC inobatsirawo kuvandudza kunamatira uye kusimba, zvichiita kuti ive chikamu chakakosha chemazuva ano ekuvaka maumbirwo.

Gypsum plaster:

2.1.Ingredients uye maitiro:

Yakagadzirwa kunyanya ye calcium sulfate dihydrate, gypsum chinhu chinoshandiswa zvakanyanya chekuvaka chinozivikanwa nekudzivirirwa kwemoto, kuvharidzira ruzha uye nzvimbo yakatsetseka.Inowanzoshandiswa sechinhu chinoshongedza chemadziro uye denga, zvichipa nzvimbo yakanaka uye yakasimba.

2.2.Application mukuvaka:

Gypsum plaster ine huwandu hwakasiyana hwekushandisa muindasitiri yekuvaka, kusanganisira mukati memadziro kupera, zvekushongedza zvinhu uye moulding.Kuita kwayo kwakasiyana-siyana, nyore kushandisa uye yakanakisa kudzivirira moto inoita kuti ive sarudzo yekutanga yezvivakwa zvekugara uye zvekutengesa.

HPMC yakasungirirwa gypsum plaster:

3.1.Manufacturing process:

Kugadzirwa kweHPMC yakasungirirwa gypsum kunosanganisira kuiswa kwehydroxypropyl methylcellulose mune gypsum matrix.Izvi zvinowanikwa kuburikidza nekunyatsodzorwa kusanganisa maitiro, kuve nechokwadi chekuti HPMC zvimedu zvakagoverwa zvakaenzana mukati meiyo gypsum matrix.Mhedzisiro yacho inoumbwa zvinhu zvinogara nhaka zvakanakira HPMC uye gypsum.

3.2.Hunhu hweHPMC yakasungwa gypsum:

Iko kusanganiswa kweHPMC uye gypsum inopa iyo inoumbwa yakasarudzika zvivakwa.Izvi zvinosanganisira kukwidziridzwa kushanda, kunamira kwakagadziridzwa, yakawedzerwa nguva yekumisikidza uye kuwedzera kusimba.HPMC zvinongedzo zvinobatsira kuchengetedza hunyoro, kudzivirira kuoma nguva isati yakwana uye kuve nechokwadi chekuenderana uye kutsetseka kupera.

Kushandiswa kweHPMC yakasungwa gypsum:

4.1.Wall inopera:

HPMC yakasungirirwa gypsum plaster inowanzoshandiswa semadziro ekuvhara zvinhu.Kuvandudza kushanda kwayo kunoita kuti zvive nyore kuisa uye kupedza, zvichikonzera nzvimbo yakatsetseka uye inoyevedza.Iyo yakawedzera nguva yekumisikidza yakapihwa neHPMC inova nechokwadi chekuti plasterer ine nguva yakakwana yekuzadzisa yaunoda kupera.

4.2.Decorative style:

Iyo composite inoshandiswawo kugadzira zvishongo zvekushongedza uye zvivakwa zvekugadzira.Kuita kwayo kwakasiyana-siyana kunobvumira dhizaini yakaoma uye ruzivo, ichipa vagadziri vezvivakwa nevagadziri vane dzakasiyana siyana dzekugadzira mikana.

4.3.Kugadzirisa uye kupora:

HPMC yakasungirirwa plaster inokodzera kugadzirisa uye kudzoreredza mapurojekiti uko kuenderana kwayo nenzvimbo iripo plaster uye kusimba kwakasimba kunoita basa rakakosha.Inobvumira kugadzirisa kusina musono uye inovimbisa hupenyu hurefu hwepamusoro pekugadzirisa.

Zvakanakira zveHPMC zvakasungwa gypsum:

5.1.Vandudza processability:

Kuwedzerwa kweHPMC kunowedzera kushanda kwegypsum plaster, kuita kuti kushandiswa uye kupedza kuve nyore.Izvi zvinonyanya kubatsira kune vanopurasita sezvo zvichibvumira kutonga kukuru uye kunyatsoita panguva yekupurasita.

5.2.Wedzera nguva yekusimbisa:

Iyo yakawedzerwa nguva yekumisikidza yakapihwa neHPMC inova nechokwadi chekuti plasterer ine nguva yakakwana yekupedzisa kunyorera uye kuzadzisa zvaunoda.Izvi zvinobatsira pamapurojekiti makuru kana panodiwa nguva yekumisikidza yakanonoka.

5.3.Wedzera adhesion:

HPMC inobatsira kuvandudza kunamatira, zvichikonzera chisungo chakasimba pakati pepurasita uye substrate.Ichi chivakwa chakakosha kusimba uye hupenyu hurefu hweiyo yakapedzwa nzvimbo.

5.4.Kuchengeta mvura:

Kugona kwekubata mvura kweHPMC kunodzivirira kuoma kwepurasita nguva isati yakwana, zvichikonzera kupera kwakafanana, kwakatsetseka.Izvi zvinonyanya kukosha munzvimbo dzakaoma kana kuti pakushanda panzvimbo huru, uko kuchengetedza hunyoro hwakafanana hunogona kunetsa.

5.5.Dhizaini Yakasiyana-siyana:

Mamiriro akaumbwa eiyi HPMC yakasungirirwa plaster inoipa kuita zvakasiyana mukugadzira uye kushandisa.Inogona kuumbwa kuita akasiyana maumbirwo uye mafomu, zvichiita kuti ive yakakodzera kune ese echinyakare uye emazuva ano ekuvaka masitaera.

mukupedzisa:

Hydroxypropylmethylcellulose (HPMC) -bonded plaster inomiririra kufambira mberi kukuru mune zvekuvaka.Nekubatanidza zvinhu zvinobatsira zveHPMC uye gypsum, iyi composite inopa yakagadziridzwa kushanda, yakawedzerwa nguva yekumisikidza, yakawedzera kunamatira uye kuchengetedza mvura.Aya maficha anoita kuti ive inogoneka uye yakakosha sarudzo kune akasiyana ezvivakwa zvekushandisa, zvinosanganisira zvekuvharisa madziro, moldings uye mapurojekiti ekugadzirisa.Sezvo indasitiri yekuvaka iri kuramba ichishanduka, HPMC yakasungirirwa gypsum plaster inomira pachena seyakagadzikana uye yakakwirira-inoshanda mhinduro yemazuva ano ekuvaka maitiro.
