HydroxyethylcelluloseHECipolymer isinganyungudike mumvura inonyungudika mumvura inopisa neinotonhora. Hydroxyethylcellulose series HEC ine mhando dzakasiyana dze viscosities, uye mhinduro dzemvura dzese dziri mvura dzisiri dzeNewtonian.
Hydroxyethyl cellulose chinhu chakakosha chinowanikwa mumakemikari ezuva nezuva. Haingogone chete kuvandudza viscosity yezvizoro zvemvura kana emulsion, asiwo inovandudza kupararira uye kugadzikana kwefuro.
mukana:
1. Ine mvura yakakwana mumuviri.
2. Ine kugadzikana kukuru uye kuzara.
3. Hunhu hwakanaka kwazvo hwekugadzira mafirimu.
4. Ine mashandiro anodhura zvakanyanya.
5. Ine mwero wakanaka wekutsiva chigadzirwa ichi kuti chirambe chakagadzikana kwenguva refu chinodzivirira kukosora.
Dhigirii rePolymerization:
Kune mapoka matatu ehydroxyl pachikamu chimwe nechimwe cheanhydroglucose mu cellulose, iyo inorapwa nealkali mu aqueous sodium hydroxide solution kuti iwane cellulose sodium salt, uye yobva yaitwa etherification reaction ne ethylene oxide kuti igadzire hydroxyethyl cellulose ether. Mukugadzira hydroxyethyl cellulose, ethylene oxide inogona kutsiva mapoka ehydroxyl pa cellulose, uye yoita chain polymerization reaction nemapoka ehydroxyl mumapoka akatsiviwa.
Hydroxyethylcellulose ine hunhu hwakanaka hwekunyorovesa mvura. Mvura yayo inonyorovesa uye yakafanana, ine kunyorova uye kuenzana. Saka, zvizoro zvine hydroxyethyl cellulose zvine kugadzikana kwakanaka uye zvakakwana mumudziyo, uye zvinopararira zviri nyore pabvudzi neganda kana zvikashandiswa. Inoshandiswa zvakanyanya muzvinyoro, mukuwacha muviri, sipo dzemvura, majeli ekugera uye furo, mushonga wemazino, madeodorant akasimba anodzivisa kubuda ropa, matishu (vacheche nevakuru), majeli ekuzora.
Pamusoro pekudzora mvura,hydroxyethyl celluloseine hunhu hwakanaka hwekuumba firimu. Firimu rakaumbwa rine chokwadi chekuti richave riri muchimiro chakakwana pasi pe350x uye 3500x mirror scanning, uye rinopa kunzwa kwakanaka kweganda rakatsetseka kana rikaiswa pazvizoro.
