Hydroxypropyl methylcellulose (HPMC) chinhu chinoshandiswa zvakanyanya mumaindasitiri chinoshandiswa zvakanyanya mukugadzira upfu hwemadziro, kunyanya pakushandisa mukati nekunze.
Sumo yeupfu hweHPMC:
Tsanangudzo uye maumbirwo:
Hydroxypropyl methylcellulose, inonzi HPMC, i cellulose ether yakagadziriswa inobva mu cellulose yechisikigo. Inogadzirwa nekushandisa makemikari kugadzirisa cellulose, kabhohaidhiretsi yakaoma inowanikwa mumadziro emasero emiti. Kuchinja kunosanganisira kuiswa kwehydroxypropyl ne methyl groups muchimiro che cellulose, zvichikonzera polymer inonyungudika mumvura uye inoshanda zvakanyanya.
Hunhu hwemuviri uye hwemakemikari:
Kunyungudika: HPMC inonyungudika mumvura, zvichiita mhinduro yakajeka uye isina ruvara. Kunyungudika kunogona kugadziriswa nekuchinja mwero wekutsiva (DS) panguva yekugadzira.
Kusviba: HPMC inopa kusviba kwakadzorwa uye kwakafanana mumushonga. Hunhu uhwu hwakakosha mukugadzira putty yemadziro sezvo huchikanganisa kushanda zvakanaka uye hunhu hwekushandisa kwechinhu chacho.
Kupisa kwemafuta: HPMC inoratidza kupisa kwemafuta, zvinoreva kuti inogona kugadzira gel kana yapiswa. Hunhu uhwu hunokosha mune mamwe mashandisirwo apo kupiswa kwemafuta kunodiwa.
Kushandiswa kweHPMC muputty yemadziro:
Putty yemadziro yemukati:
1. Kubatana uye kunamira:
HPMC inowedzera hunhu hwekubatanidza ma putty emadziro emukati, zvichiita kuti zvive nyore kunamira pa substrates dzakadai sekongiri, stucco kana drywall.
Maumbirwo e HPMC's modified cellulose structure anoita firimu rakatetepa pamusoro, zvichipa chisungo chakasimba uye chinogara kwenguva refu.
2. Kugadziriswa uye nyore kushandisa:
Kupenya kwakadzorwa kweHPMC kunoita kuti putty ishande zvakanaka, zvichiita kuti ikwanise kuiswa zvakanaka panzvimbo dzemukati.
Inodzivirira kudonha nekudonha kwemvura panguva yekuisa uye inoita kuti ipfekedzwe zvakaenzana.
3. Kuchengetwa kwemvura:
HPMC inoshanda senzira yekuchengetedza mvura, ichidzivirira kubuda kwemvura nekukurumidza panguva yekuoma. Izvi zvinobatsira kuvandudza kunyorova kwemvura muputty, zvichiita kuti simba riwedzere.
Putty yekunze yemadziro:
1. Kudzivirira mamiriro ekunze:
HPMC inowedzera simba rekudzivirira mamiriro ekunze kwemadziro uye inodzivirira kubva kumigumisiro yakaipa yezuva, mvura uye kuchinja kwekushisa.
Firimu repolymer rinogadzirwa neHPMC rinoshanda sechidziviriro, richidzivirira kupinda kwehunyoro uye richichengetedza kusimba kwependi.
2. Kudzivirira kutsemuka:
Kuchinjika kweHPMC kunobatsira kuti putty yekunze yemadziro isatsemuke. Inobatsira kuti substrate ifambe pasina kukanganisa kusimba kwependi.
Hunhu uhwu hwakakosha kune zvinoshandiswa kunze zvinosangana nematambudziko ezvakatipoteredza.
3. Kugara kwenguva refu:
HPMC inovandudza kugara kwenguva refu kweputty yekunze nekuwedzera kuramba kwayo kusingakuvadzi, kukuvadzwa uye kusvibiswa nemakemikari.
Firimu rekudzivirira rinogadzirwa neHPMC rinobatsira kuwedzera hupenyu hwejira uye kuderedza kudiwa kwekugadzirisa nguva nenguva.
Zvakanakira kushandisa HPMC mu wall putty:
1. Hunhu hwakagadzikana:
HPMC inoita kuti maforoma emadziro eputty ave emhando yepamusoro uye anosangana nezvinodiwa pakushanda.
2. Kuvandudza kushanda zvakanaka:
Kupenya kwakadzorwa kweHPMC kunoita kuti zvive nyore kushandisa, zvichiita kuti maitiro ekushandisa ave nyore uye ashande zviri nyore.
3. Wedzera kunamira:
Hunhu hwekunamira hweHPMC hunobatsira pakunamira kwakanaka, zvichiita kuti putty inamire zvakanaka kune akasiyana-siyana ma substrates.
4. Kuchinja-chinja:
HPMC inogona kushandiswa mumhando dzakasiyana-siyana uye inogona kugadziriswa kuti ienderane nezvinodiwa zvepurojekiti.
mhedziso:
Upfu hweHydroxypropyl methylcellulose (HPMC) chinhu chakakosha mukugadzira putty yemadziro mukati nekunze. Hunhu hwayo hwakasiyana, kusanganisira kunyungudika, kudzora viscosity uye kugona kugadzira firimu, zvinoita kuti ive yakanaka pakuvandudza mashandiro uye kugara kwenguva refu kwependi yemadziro. Kunyangwe ikashandiswa mukati kana panze, putty yemadziro ine HPMC inopa mhando yakafanana, kushanda kuri nani uye dziviriro inogara kwenguva refu kubva kuzvinhu zvakatipoteredza. Sezvo indasitiri yekuvaka ichiramba ichichinja, basa reHPMC mukugadzira putty yemadziro rinoramba riri rakakosha pakuwana magumo emhando yepamusoro uye akasimba.
