Hydroxyethyl celluloseHECis a non-ionic water-soluble polymer iyo inonyungudika mumvura inopisa uye inotonhora. Hydroxyethylcellulose series HEC ine zvakasiyana-siyana zveviscosities, uye mhinduro dzemvura dzose dzisiri dzeNewtonian fluid.
Hydroxyethyl cellulose chinhu chakakosha chekuwedzera mune zvemazuva ese makemikari zvigadzirwa. Haikwanise kungovandudza viscosity yemvura kana emulsion cosmetics, asiwo inovandudza kupararira uye kugadzikana kwefuro.
mukana:
1.Ane hydration yakanaka kwazvo.
2. Ane kuwirirana kukuru uye kuzara.
3. Yakanakisa firimu-kugadzira pfuma.
4. Iine yakanyanya kudhura kuita.
5.Iyo ine dhigirii yakanakisa yekutsiva kuti ive nechokwadi chekugara kwenguva refu-anti-mildew kugadzikana kwechigadzirwa.
Polymerization degree:
Pane mapoka matatu ehydroxyl pane imwe neimwe anhydroglucose unit mu cellulose, iyo inobatwa nealkali mu aqueous sodium hydroxide solution kuti iwane cellulose sodium munyu, yobva yapinda etherification reaction ne ethylene oxide kuti igadzire hydroxyethyl cellulose ether. Mukugadzira hydroxyethyl cellulose, ethylene oxide inogona kutsiva mapoka ehydroxyl pa cellulose, uye kuita cheni yepolymerization reaction nemapoka ehydroxyl mumapoka akatsiviwa.
Hydroxyethylcellulose ine yakanaka kwazvo hydration zvivakwa. Mhinduro yaro ine aqueous yakatsetseka uye yakafanana, ine mvura yakanaka uye inoyerera. Nokudaro, zvizoro zvine hydroxyethyl cellulose zvine hutano hwakanaka uye huzere mumudziyo, uye zvinopararira nyore nyore pabvudzi uye ganda kana zvichishandiswa. Inoshandiswa zvakanyanya mumaconditioners, kugeza muviri, sipo dzemvura, kugera gels uye furo, mushonga wemazino, yakasimba antiperspirant deodorants, tishu (vacheche nevakuru), mafuta ekuzora.
Kuwedzera kune fluid control,hydroxyethyl celluloseine yakanakisa firimu kugadzira zvivakwa. Iyo firimu yakaumbwa inovimbiswa kuve muchimiro chakazara pasi pe350x uye 3500x girazi scanning, uye inounza yakanakisa yakatsetseka ganda kunzwa kana yaiswa kune zvizorwa.
