Iyo viscosity index yehydroxypropyl methylcellulose indekisi yakakosha.Iyo viscosity haimiriri kuchena.Iyo viscosity ye cellulose HPMC zvinoenderana nemaitiro ekugadzira.Nzvimbo dzakasiyana dzekushandisa dzinofanira kusarudza cellulose HPMC ine maviscosities akasiyana, kwete iyo yakakwira viscosity ye cellulose HPMC, zviri nani!Chakarurama chakarurama!
1. Viscosity control
Yakakwira-viscosity hydroxypropyl methylcellulose haigone kuburitsa yakakwira cellulose chete nekupukuta uye kutsiva nitrogen mukugadzira.Kazhinji, kugadzirwa kwe-high-viscosity cellulose muChina hakugone kudzorwa.Zvisinei, kana mutsara weokisijeni mita unogona kuiswa muketero, kugadzirwa kweviscosity yayo kunogona kudzorwa nemaitiro.
2. Kushandiswa kwemubatanidzwa mumiriri
Pamusoro pezvo, tichifunga nezve kutsiva kumhanya kwenitrogen, zviri nyore kugadzira zvigadzirwa zvepamusoro-viscosity zvisinei nekuti system yacho haina mhepo sei.Ehe, dhigirii repolymerization yedonje rakanatswa rakakosha zvakare.Kana izvo zvisingashande, zviite ne hydrophobic association.Kune vamiriri vemasangano munzvimbo ino muChina.Ndeupi rudzi rwemubatanidzwa mumiriri wekusarudza ane simba guru pakuita kwechigadzirwa chekupedzisira.
3. Hydroxypropyl content
Iyo yakasara okisijeni mu reactor inokonzera kuparara kwe cellulose uye kuderera kwema molecular uremu, asi yakasara okisijeni inogumira, chero bedzi mamorekuru akatyoka achibatanidzwazve, hazvisi zvakaoma kuita yakakwirira viscosity.Nekudaro, iyo saturation rate ine zvakawanda zvekuita nezviri mukati mehydroxypropyl.Mamwe mafekitari anongoda kuderedza mutengo uye mutengo, asi haadi kuwedzera zvirimo zvehydroxypropyl, saka mhando haigone kusvika pamwero wezvigadzirwa zvekunze zvakafanana.
4. Zvimwe zvinhu
Chiyero chekuchengetedza mvura kwechigadzirwa chine hukama hukuru nehydroxypropyl, asi kune iyo yese maitiro maitiro, inotaridzawo chiyero chekuchengetedza mvura, alkalization effect, chiyero chemethyl chloride uye propylene oxide, alkali concentration uye kuchengetedza mvura.Chiyero chekotoni yakanatswa inosarudza kushanda kwechigadzirwa.
