Quaternized hydroxyethyl cellulose

Quaternized hydroxyethyl cellulose (QHEC) ishanduro yakagadziridzwa yehydroxyethyl cellulose (HEC) iyo yakabatwa nequaternary ammonium compound. Uku kugadziridzwa kunoshandura zvimiro zveHEC uye kunoguma mune cationic polymer ine huwandu hwakasiyana hwemashandisirwo, kusanganisira muzvigadzirwa zvekuchengetedza munhu, machira, uye mapeji ekuputira.

Iyo quaternization yeHEC inosanganisira kuwedzera kweiyo quaternary ammonium compound kune HEC molecule, iyo inosvitsa chaji yakanaka mupolymer. Iyo inonyanya kushandiswa quaternary ammonium compound yechinangwa ichi ndeye 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Mushonga uyu unopindirana nemapoka ehydroxyl paHEC molecule, zvichiita kuti pave nechaji yakanaka QHEC molecule.

Imwe yemashandisirwo ekutanga eHEC iri muzvigadzirwa zvekuchengetedza munhu, senge shampoos, maconditioners, uye zvigadzirwa zvekugadzira bvudzi. HEC inopa yakanakisa kugadzirisa uye kudzikisira zvivakwa kune bvudzi, zvichiita kuti zvive nyore kupeta uye maitiro. HEC inoshandiswa zvakare seyakakora uye rheology modifier mune izvi zvigadzirwa, ichipa yakasarudzika mameseji uye inosimudzira kuita kwese.

Mumachira ekushandisa, HEC inoshandiswa senge saizi ajenti yekotoni uye mamwe mafiber echisikigo. HEC inogona kuvandudza kuoma uye abrasion kushorwa kwemachira, zvichiita kuti zvive zvakasimba uye zviri nyore kubata panguva yekugadzira. HEC inogonawo kuvandudza kusungirirwa kwedhayi uye mamwe maajenti ekupedzisa kumucheka, zvichiita kuti kuve nemavara akajeka uye zviri nani kushambidza kumhanyisa.

HEC inoshandiswawo mumapepa ekuputira kuvandudza kudzivirira kwemvura uye kudhindwa kwepepa. HEC inogona kuvandudza kusungirirwa kwekuputira uye kuderedza kupinda kwemvura neingi mumapepa efiber, zvichikonzera kupinza uye kwakanyanya kudhinda. HEC inogonawo kupa yakanakisa kutsetseka kwepamusoro uye kupenya kune pepa, ichiwedzera kutaridzika kwayo uye tactile zvimiro.

Imwe yemabhenefiti akakosha eHEC ndeye cationic hunhu, hunoita kuti ishande zvakanyanya mumagadzirirwo ane anionic surfactants. Anionic surfactants inowanzoshandiswa muzvigadzirwa zvekuchengetedza munhu, asi inogona kushamwaridzana nevasina-ionic thickeners, zvakadai seHEC, uye kuderedza kushanda kwavo. HEC, iri cationic, inogona kuumba kupindirana kwakasimba kwemagetsi neanionic surfactants, zvichikonzera kuwedzera kukora uye kugadzikana.

Imwe bhenefiti yeHEC ndeyekuenderana kwayo nehuwandu hwakawanda hwezvimwe zvinongedzo. HEC inogona kushandiswa nemamwe cationic, anionic, uye isiri-ionic zvigadzirwa pasina kukanganisa kushanda kwayo. Izvi zvinoita kuti ive chinhu chakasiyana-siyana chinogona kushandiswa mumhando dzakasiyana-siyana dzekugadzirisa uye kushandiswa.

HEC inowanikwa mumagiredhi akasiyana-siyana uye viscosities, zvichienderana neiyo chaiyo yekushandisa uye yekugadzira zvinodiwa. Inowanzo kupihwa sehupfu hunogona kuparadzirwa nyore nyore mumvura kana zvimwe zvinonyungudutsa. QHEC inogonawo kugoverwa sechinhu chisati chave neuturalized kana self-neutralizing chigadzirwa, izvo zvinobvisa kudiwa kwekuwedzera kwekutora matanho panguva yekugadzira.

Muchidimbu, quaternized hydroxyethyl cellulose ishanduro yakagadziridzwa yehydroxyethyl cellulose yakabatwa nequaternary ammonium compound. HEC ndeye cationic polymer ine huwandu hwakasiyana hwekushandisa, kusanganisira mune zvekuchengetedza zvigadzirwa zvemunhu, machira, uye mapeji ekuputira. HEC inopa yakanakisa kugadzirisa uye kukora zvivakwa, inosimudzira mashandiro eanionic surfactants, uye inowirirana nehuwandu hwakawanda hwezvimwe zvinongedzo. Iko kuita kwakasiyana-siyana uye kuita kweHEC kunoita kuti ive chinhu chakakosha mukuumbwa kwakasiyana-siyana uye mashandisirwo.
