Iyo viscosity index ye hydroxyprusyl methylcellose index yakakosha kwazvo. Iyo visikoity haina kumiririra kuchena. Iyo viscosity ye cellulose hpmc zvinoenderana nekugadzira maitiro. Nzvimbo dzakasiyana dzekushandisa dzinofanira kusarudza Cellulose HPMC ine zvisizvo zvevema visikoka, kwete yakakwira viscosity ye cellulose hpmc, zvirinani! Chii chakarurama chakarurama!
1. Viscosity Control
Yakakwira-viscosity hydroxyprospropyl methylcellose haigoni kubereka zvakanyanya mheremalose cellulose chete nekubuda uye nitrogen kutsiva mukugadzira. Kazhinji, kugadzirwa kwekakwirira-viscosity cellulose mu china haigone kudzorwa. Nekudaro, kana okisi yeOxygen metres inogona kuiswa muKettle, kugadzirwa kweVaisikoka kwaro kunogona kudzorwa.
2. Kushandiswa kweAgent Onessation Agent
Mukuwedzera, kufunga nezvekumhanya kwekutsiva kweNitrogen, zviri nyore kuburitsa zvigadzirwa zvepamusoro-viscosity zvisinei nekuti system yemigwagwa sei. Ehe, iyo degree rePolymerization yekotoni yakanatswa ndiyo yakakoshawo. Kana izvo zvisingashande, itai zviite nehydrophobic ushamwari. Kune vamiririri venhamo munzvimbo ino kuChina. Rudzi rwesangano rei rekudyidzana kuti risarudze rine pesvedzero huru pakuita kwechigadzirwa chekupedzisira.
3. Hydroxyprupropyl zvemukati
Iyo yakasara oksijeni iri mune inokonzeresa inokonzeresa mheremalose uye kuderera kwehuremu hwemanyorero, asi okisiligine yakasara ishoma, chero bedzi mamalekyu akaomeserwa, hazvina kuoma kuita viscosity yakakwira. Nekudaro, chiyero cheguta chine zvakawanda chekuita nezviri mukati mehydroxyprupyl. Mamwe mafungu anongoda kuderedza mutengo nemutengo, asi vasingade kuwedzera zviri mukati mehydroxyropropyl, saka kunaka hakugone kusvika padanho rezvigadzirwa zvakafanana.
4. zvimwe zvinhu
Iyo yekuchengetwa kwemvura yechigadzirwa ine hukama hukuru ne hydroxypruppropropropropropyl, asi zvakare maitiro ese ekugadzirisa mvura, alkalization yemethyl chloride, ratio ye methyl chloriide Iyo ratio yekunyatsonatswa cottoni inosarudza kuita kwechigadzirwa.
