HPMC (HydroxyprEpropyl methylcellose) Inoshandiswa kwakakosha kunoshandiswa zvakanyanya muzvivakwa zvekuvaka, kunyanya mune zvigadzirwa zvakaita sePutty poda, madekwana uye majasi. Iyo inonyura-soluble polymer inowanzobata inobata basa rekuita zvekuvakisa nekugadzirisa zvavakaita. MuPutty poda, iyo maVisikoka akasiyana eHPMC ine kukosha kwakakosha pakuita kwechigadzirwa, sekushanda, kuchengetwa kwemvura, nguva yekudzvinyirira uye kuoma nguva.
1. Basa rekutanga reHPMC
MuPutty poda, mashandiro makuru eHPMC anosanganisira:
Kuvandudza Kwekuchengetwa Kwemvura: HPMC inogona kunyatso kudzora kulatlization yemvura muPutty Powder yekuvaka, nekukonzera kudzvinyirira kwekutyisa uye kudzivisa kuparadza kwekutyisa, zvichikonzera kuparara kana kusingaenzaniswi.
Kuvandudza Kurovedzera: Nekugadzirisa iyo visikopa yeHPMC, iri kuuya yePutty poda inogona kuvandudzwa, ichiita kuti zvive nyore kushandisa uye kutsvedza.
Kuwedzera Kubatira Simba: HPMC kunogona kuwedzera simba rekubatanidza pakati pePutty poda uye substrate, kugadzirisa iyo kuderedza yePutty layer, uye kuderedza kudedera.
Kugadziriswa
2. Simba reVanhu Vakasiyana HPMC pane putty poda
(1) Iyo pesvedzero yeyakaderera viscosity HPMC pane putty poda
Yakadzika viscosity HPMC inowanzoshandiswa muPutty poda mafomula inoda yakakwirira fluity. Simba rayo rinonyanya kuratidzwa mune zvinotevera zvinhu:
Kushanda: Yakadzika viscosity HPMC ichaita POWDY POWDY ine zvishoma zvishoma nezvishoma uye zviri nyore kuputira uye kunyorera zvakanyanyisa panguva yekuvaka. Izvi zvakakodzera nzvimbo dzekuvaka dzinoda kushanda kwakakwirira kushanda, kunyanya kana uchishandisa munzvimbo dzakakura.
Kuchengeta kwemvura: Kubva kaya yemanyoreti yeiyo low viscosity Hpmc ipfupi uye kuwirirana pakati pemamolekora, iko kuchengetwa kwemvura kwePutty poda kune varombo. Izvi zvinogona kukonzera iyo fungidziro yekupwanya nyore nyore kana kurasikirwa neyemusimbe mushure mekuvaka.
Adhishing: Iyo yekukwezva yeyakaderera viscosity HPMC iri isina kusimba, saka kuderedza kwaro kune mamwe manhamba anogona kunge asina kusimba seyekutanga viscosity HPMC. Inoda kushandiswa pamwe chete nezvimwe zvinhu zvinowedzera kufambira mberi.
(2) Mhedzisiro yeVepakati Viscosity HPMC pane Putty poda
Pakati peva viscosity HPMC inowanzo shandiswa mune yakawanda standard putty putty poda mafomula uye ine yakanaka yakazara kuita:
Kushanda
Kuchengeta mvura: Pakati pevaHpmc inoitwa nekuchengetwa kwemvura uye inogona kunonoka kuwiriraniswa kwemvura, ichiratidza kuti iri kuiswa kwekutyisa panguva yekuvaka uye kufanana kwekuomesa.
ADHesion: HPMC yeiyi viscosity level inopa mwero wakadhindwa, izvo zvinogona kuve nechokwadi chekudyidzana kwakanaka pakati peiyo putty layer uye substrate uye kudzivirira iyo yekuvhara kubva kure.
(3) Mhedzisiro yeKukuru viscosity HPMC pane putty poda
Yakakwira viscosity HPMC yakakodzera putty poda mafomula inoda kushanda kwayo, kunyanya kune zvikumbiro izvo zvinoda kuwedzera kwekuchengetwa kwemvura uye kusimba kwakasimba. Maitiro ayo anosanganisira:
Kuita Kwekuvaka: Yakakwira viscosity HPMC inogadzira Poda poda yakawanda viscous pakuvakwa, asi inogona kupa simba rakasimba rekudzivirira kana kudonhedza, uye yakakodzera kuvakwa pamadziro emidziyo kana kuti inoda nzvimbo.
Kudzokorora kwemvura: Yakakwira viscosity HPMC ine mvura yakanakira kuita, iyo inogona kudzivirira zvinobudirira poda poda kubva pakuoma nekukurumidza panguva yekuvaka, nekudaro kuderedza njodzi yekuvakwa.
ADHesion: Yakakwira viscosity HPMC inopa kudiwa kwakasimba, kunyanya kune subsrates ine nzvimbo dzakakwirira dzekudyidzana, dzakadai simbi dzakafanana nemakiromita, izvo zvinogona kuve nechokwadi chekusimbisa kwakasimba kweiyo putty layer.

Kuti uzadzise zvakanakisa putty poda maitiro, zvinowanzo kuve zvakafanira kusarudza iyo yakakodzera HPMC viscoss zvichienderana nenzvimbo chaiyo yekuvaka uye shandisa zvinodiwa. Kazhinji kutaura, kuderera viscosity HPMC kwakakodzera kune yakakura-nzvimbo yekunyorera application uye kukurumidza kuvaka; Pakati peva viscossity HPMC yakakodzera kuGeneral Wall Kugadziriswa uye kuunganidza kuvaka, kuyera kwekuvaka kuita, kudzokorora kwemvura uye kuderedza. Yakakwira viscosity HPMC inoshandiswa munzvimbo dzinokosha dzekuvaka dzinoda nguva yakareba yakavhurika uye kusimba kwakasimba.
HPMC ine dzakasiyana viscookiti ine kukosha kwakakosha pakuita kweiyo putty poda. Viscosity yakaderera yakakodzera kuti apprilies neyakareba zvinodiwa, pakati pekuvona Zvinoenderana nezvakananga kushandiswa kweiyo HPMC viscosity inogona kuongorora mashandiro ekuvaka uye mhando yePutty poda uye kusangana nezvinodiwa zvekuvaka zvakasiyana. Naizvozvo, mukugadzirwa uye kushandiswa kwePutty poda, zvakakosha kwazvo kusarudza HPMC neViskopi yakakodzera.
