Putty chinhu chakakosha chekuvaka chinoshandiswa kumadziro ekusimudzira, uye kuita kwayo zvakananga kunokanganisa kuderedza kwependi uye hunhu hwekuvaka. Mukuumbwa kwePutty, cellulose ether vanopinda vanoita basa rakakosha.Hydroxyprupyl methylcellose (HPMC), Seimwe yeanonyanya kushandiswa cellulose cellulose erinhery, inogona kunatsiridza zvinobudirira viscosity, kuita kwekuvaka uye kugadzikana kwekuchengetedza kwekutyisa.
1. Zvekutanga zvivakwa zve hydroxypropyl methylcellose
HPMC ndeye isiri-ionic mvura-inokwira mvura yakakwenenzverwa neakanakisa, kudzivirirwa kwemvura, kupararira, kusimbisa uye mafirimu-ekuumba midziyo. Yayo viscosity inokanganiswa neiyo degree rekutsiva, degree rePolymerization uye Solubility mamiriro. Mhedzisiro yekugadzirisa yekusagadzikana kweSimba inoratidza maitiro ehunhu hwedenga, kureva kuti ratehwe richawedzera, iro rondedzero yemhinduro inoderera, iyo inokosha pakuvaka putty.
2. Mhedzisiro yeHPMC pane putty viscosity
2.1 Kukakavara Kunoita
HPMC inoumba yakakwira viscosity solution mushure mekunyungudika mumvura. Kubata kwayo kwakasimba kunonyanya kuratidzwa mune zvinotevera zvinhu:
Kuvandudza iyo thisty yePutty: HPMC inogona kuchengeta iyo putty pane yakakwira viscosity kana ichimira kuti udzivise kusimuka, uye kuderedza visikoka kana ichikwenya nekuvandudza kushanda kwekuvaka.
Kuvandudza Kuwedzerwa kwePutty: Mari yakakodzera yeHPMC inogona kuvandudza lubricity yePutty, kugadzira kupuruzira zvishoma uye kudzora kudzikisira.
Kubata simba rekupedzisira rePutty: Iko kukora kweHPMC kunoita kuti mupepuru uye zvimisikidzwa zvinhu zvakanyatso kuparadzaniswa, kudzivisa kusarongeka uye nekuvandudza maitiro ekuomesa mushure mekuvaka.
2.2 Mhedzisiro pane iyo hydration maitiro
HPMC ine yakanakisa mvura yekuchengetwa, iyo inogona kuderedza kukurumidza kwemvura mumvura muPutty layer, nokudaro nekuwedzera nguva yekudzvanywa kweiyo coment-yakavakirwa putty uye nekuvandudza simba uye kupenga kudzikisira. Nekudaro, zvakanyanyisa viscosity yeHPMC ichakanganisa kufungidzira kwemhepo uye nekuomesa kumhanya kwekutyisa, zvichikonzera mukudzikira kwekushanda kwekuvaka. Naizvozvo, huwandu hweHPMC hunoda kuve nechokwadi chekushanda paunenge uchidzivirira zvakashata mhedzisiro panguva yekuomesa.
2.3 Ukama pakati peiyo molecular uremu hweHPMC uye iyo viscosity yePutty
Iyo yakakwira iyo smecular uremu hweHPMC, iyo yakakura zvevisiko zvemhedzisiro yayo mhinduro. MuPutty, kushandiswa kwekakwirira-viscosity HPMC (serudzi rwevasitokisi yakakura kupfuura 100,000 MPA · ( . Naizvozvo, pasi pezvinhu zvakasiyana zvekuvaka, HPMC neViscosity yakakodzera inofanira kusarudzwa kuenzanisa kuchengetedza kwemvura, kushanda uye kwekupedzisira kuita.
2.4 Mhedzisiro yeHPMC Dosage pane putty viscosity
Mari yekusagadzikana ®hpmc yakawedzerwa ine kukosha kwakakosha pane iyo viscosity yePutty, uye iyo Dosage inowanzo pakati pe0.1% uye 0.5%. Kana Dosage yeHPMC yakaderera, iyo inokatyamadza pane iyo putty ishoma, uye inogona kunge isingakwanise kunyatsovandudza kushanda nekuchengetwa kwemvura. Kana dosi rakanyanya kukwirira, iwo wiscothiti rakanyanya kukura, kupesana nekuvaka kunowedzera, uye kunogona kukanganisa kumhanya kwekuomesa kwekuputika. Naizvozvo, zvakafanira kusarudza huwandu hwakakodzera hweHPMC zvinoenderana formula yeiyo putty uye nzvimbo yekuvaka.
Hydroxyprusyl methylcellose inoita basa rekuita mukuremerwa, kudzokorora kwemvura uye kugadzirisa basa mukubata. Uremu hwemanyorerwe, degree rekutsiva uye kuwedzera huwandu hweHpcichakanganisa visikopa yePutty. Mari yakakodzera yeHPMC inogona kuvandudza kuiswa uye kudzikisira kwemvura kwekutyisa, nepo kunyanyisa kuwedzera kunogona kuwedzera kuoma kwekuvaka. Naizvozvo, mukushandiswa chaiko kwePutty, iyo viscosity maitiro uye zvinodiwa pakuvaka yeHPMC inofanirwa kunge ichinyatsonzwisiswa, uye formula inofanirwa kugadziriswa zvine musoro kuti uwane basa rekuvaka uye rekupedzisira.
