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 chimbo chekuyeresa okisijeni chinogona kuiswa muketero, kugadzirwa kwe viscosity yayo kunogona kudzorwa zvine hunyanzvi.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.
Iyo mwenje transmittance yehydroxypropyl methylcellulose inonyanya kukanganiswa neanotevera mapoinzi:
1. Hunhu hwezvigadzirwa.
2. Mhedzisiro ye alkalization.
3. Process ratio.
4. Chiyero chezvinonyungudutsa.
5. Neutralization effect.
Iyo yakasara okisijeni iri mubhailer inokonzeresa kuderedzwa kweselulosi uye kudzikiswa kwehuremu hwemamorekuru, asi iyo yakasara okisijeni inogumira, kana kungobatanidza mamorekuru akakuvadzwa, zvichiita kuti viscosity yakakwira zvive nyore.Nekudaro, iyo nhanho yemvura yakazara inewo kuwirirana kwakasimba pamwero wehydroxyproline.Mamwe mafekitori anongoda kudzikisa mutengo uye mutengo, uye haadi kuwedzera zvirimo zvehydroxyproline kuitira kuti mhando yacho isapfuure mwero wezvigadzirwa zvinogadzirwa kunze kwenyika.Chiyero chekudzivirira chechigadzirwa chine chekuita nemvura phenol, asi kazhinji, maitiro ekuita anotaridzawo dhigirii rekuchengetedza, chiyero chealkali, methyl chloride uye propylene oxide, kuwanda kwealkali uye chiyero chemvura nedonje chinotarisa kushanda kwayo. .
