Hydroxypropyl methylcellulose (HPMC) chinhu chinogoneka mumaindasitiri chinoshandiswa zvakanyanya mumadziro putty poda maumbirwo, kunyanya kune emukati uye kunze kwekushandisa.
HPMC poda sumo:
Tsanangudzo uye maumbirwo:
Hydroxypropyl methylcellulose, inonzi HPMC, yakagadziridzwa cellulose ether inotorwa kubva kune yakasikwa cellulose.Inogadzirwa nekemikari inoshandura cellulose, yakaoma carbohydrate inowanikwa mumadziro emasero ezvirimwa.Kugadziridza kunosanganisira kuunzwa kwehydroxypropyl uye methyl mapoka mune cellulose chimiro, zvichikonzera kunyungudika kwemvura uye kunoshanda zvakasiyana-siyana polymer.
Zvenyama nemakemikari zvivakwa:
Solubility: HPMC inonyungudika mumvura, ichigadzira mhinduro yakajeka uye isina ruvara.Solubility inogona kugadziridzwa nekushandura dhigirii rekutsiva (DS) panguva yekugadzira.
Viscosity: HPMC inopa inodzorwa uye inowirirana viscosity kune mhinduro.Ichi chivakwa chakakosha mumadziro putty maumbirwo sezvo achikanganisa kushanda uye mashandisiro maitiro echinhu.
Thermal gelation: HPMC inoratidza kupisa kwemafuta, zvinoreva kuti inogona kuumba gel kana ichipisa.Ichi chivakwa chakakosha mune mamwe maapplication panodiwa gelling.
Kushandiswa kweHPMC mumadziro putty:
Interior wall putty:
1. Kubatana uye kunamatira:
HPMC inokwidziridza zvisungo zvemukati zvemukati madziro putties, kuve nechokwadi chekunamatira zvirinani kune substrates senge kongiri, stucco kana drywall.
HPMC's yakagadziridzwa cellulose chimiro inoumba firimu rakatetepa pamusoro, richipa yakasimba uye yakasimba bond.
2. Processability uye nyore kushandisa:
Iyo inodzorwa viscosity yeHPMC inopa iyo putty yakanakisa kushanda, ichibvumira kuti ishandiswe mushe uye nyore kune emukati maficha.
Iyo inodzivirira kudonha uye kudonha panguva yekushandisa uye inova nechokwadi chekupfeka yunifomu.
3. Kuchengeta mvura:
HPMC inoshanda sechinhu chinochengetedza mvura, ichidzivirira kukurumidza kubuda kwemvura panguva yekurapa.Izvi zvinobatsira kuvandudza hydration ye putty, zvichikonzera kukura kwesimba kuri nani.
Kunze kwemadziro putty:
1. Kuramba kwemamiriro ekunze:
HPMC inosimudzira kuramba kwemamiriro ekunze kwekunze kwemadziro putties uye inodzivirira kubva kune yakashata mhedzisiro yezuva, mvura uye tembiricha shanduko.
Iyo firimu repolymer rakagadzirwa neHPMC rinoita sechivharo, kudzivirira kupenya kwemvura uye kuchengetedza kutendeseka kwejasi.
2. Crack resistance:
Iko kuchinjika kweHPMC kunobatsira mukuputsika kuramba kwekunze kwemadziro putty.Inogadzirisa kufamba kwe substrate pasina kukanganisa kuvimbika kwejasi.
Ichi chivakwa chakakosha kune ekunze maapplication akaoneswa kushushikana kwezvakatipoteredza.
3. Kugara kwenguva refu:
HPMC inovandudza kusimba kwese kwekunze kweputty nekusimudzira kuramba kwayo kune abrasion, kukanganisa uye kuratidzwa kwemakemikari.
Iyo firimu inodzivirira yakaumbwa neHPMC inobatsira kuwedzera hupenyu hwekuputira uye inoderedza kudiwa kwekugara uchigadzirisa.
Zvakanakira kushandisa HPMC mumadziro putty:
1. Hunhu hwakagadzikana:
HPMC inova nechokwadi chekuti magadzirirwo emadziro emadziro ane mhando inowirirana uye anozadzisa zvinodiwa maitiro.
2. Kuvandudza kushanda:
Iyo inodzorwa viscosity yeHPMC inopa zvirinani processability, ichiita kuti maitiro ekunyorera ashande uye mushandisi-ane hushamwari.
3. Wedzera kunamatira:
Iyo inonamira zvimiro zveHPMC inobatsira mukunamira kwakanaka, kuve nechokwadi chekuti putty inonamira zvakanaka kune akasiyana ma substrates.
4. Kusiyana-siyana:
HPMC inoshanda zvakasiyana-siyana uye inogona kushandiswa mumhando dzakasiyana-siyana uye inogona kugadzirwa kuti isangane nezvinodiwa zvepurojekiti.
mukupedzisa:
Hydroxypropyl methylcellulose (HPMC) poda chinhu chakakosha mukati uye kunze kwemadziro putty formulas.Yayo yakasarudzika zvimiro, zvinosanganisira solubility, viscosity control uye firimu-kugadzira kugona, inoita kuti ive yakanaka yekusimudzira mashandiro uye kusimba kwemadziro emadziro.Ingave yakashandiswa mukati kana kunze, madziro emadziro ane HPMC anopa anowirirana mhando, yakagadziridzwa mashandiro ekushandisa uye kuchengetedzwa kwenguva refu kubva kune zvakatipoteredza zvinhu.Sezvo indasitiri yekuvaka ichienderera mberi nekushanduka, basa reHPMC mumadziro putty maumbirwo rinoramba rakakosha pakuwana yepamusoro-mhando uye inosimba kupera.
