Hydroxyethyl cellulose inogadzira

Hydroxyethyl cellulose (HEC) isiri-ionic mvura-inonyungudika polima iyo inoshandiswa zvakanyanya mumaindasitiri akasiyana semishonga, zvekuzora, kuvaka, uye machira. Sechikamu chakakosha mumashandisirwo mazhinji, vagadziri veHEC vanoita basa rakakosha mukugadzira uye kugovera kwechigadzirwa ichi chine zvakawanda.

HEC is a cellulose ether derivative iyo inogadzirwa nekemikari inogadzirisa selulosi chaiyo. Nzira yekugadzira inotanga nekucheneswa kweselulosi fibers, inoteverwa ne etherification ne ethylene oxide uye mono-chloroacetic acid kuti ibudise yekupedzisira HEC chigadzirwa. Unhu hweHEC hunoenderana nekuchena kweselulosi uye dhigirii rekutsinhanisa (DS) yemapoka ether pane cellulose musana.

Semugadziri weHEC anotungamira, kambani inofanirwa kunge iine zvivakwa zvemazuva ano uye zvishandiso kuti ive nechokwadi chemhando yepamusoro chigadzirwa. Iyo yekugadzira maitiro eHEC chiyero chakapfava pakati pemakemikari neinjiniya, ichida kunyatso kudzora mamiriro ekuita senge tembiricha, kudzvanywa, uye kuita nguva. Iyo HEC inogadzira inofanirwa kuve nehunyanzvi hunyanzvi hwekugonesa maitiro ekuita kuti igadzire HEC neinodiwa zvivakwa uye kuita.

Zvinhu zveHEC zvinogona kugadziriswa nekusiyanisa DS yemapoka ether pamusana we cellulose. A yepamusoro DS inoguma mune yakawanda hydrophilic HEC ine nani kuchengetedza mvura, nepo yakaderera DS inoburitsa yakawanda hydrophobic HEC ine nani thickening zvivakwa. Iyo HEC mugadziri anofanirwa kuve nekwaniso yekugadzira HEC neakasiyana DS maitiro kuti asangane nemhando dzakasiyana siyana dzekushandisa.

Pamusoro pekugadzira HEC neinodiwa zvivakwa, mugadziri anofanirawo kuona kuti chigadzirwa chinosangana nezvinodiwa zvemhando yepamusoro. Iko kuchena uye kuenderana kweHEC kwakakosha pakuita kwayo mumashandisirwo akasiyana siyana. Mugadziri anofanirwa kunge aine akasimba emhando yekudzora system panzvimbo yekutarisa kunaka kwechigadzirwa padanho rega rega rekugadzira. Mugadziri anofanirawo kuita bvunzo dzakakura kuti ave nechokwadi chekuti chigadzirwa chinosangana nezvinodiwa zvechishandiso chega chega.

HEC vagadziri vanofanirwawo kuzvipira kune kusimudzira uye mutoro wezvakatipoteredza. Kugadzirwa kweHEC kunosanganisira kushandiswa kwemakemikari uye simba, uye mugadziri anofanira kunge ane matanho ekuderedza kukanganisa kwezvakatipoteredza. Izvi zvinosanganisira kuderedza marara, kudzokorodza zvinhu, uye kukwenenzvera mashandisirwo esimba.

Chekupedzisira, yakanakisa HEC mugadziri anofanira kupa yakanakisa basa revatengi. Ivo vanofanirwa kuve nevanoteerera uye vanoziva vatengi sevhisi timu iyo inogona kugadzirisa chero mibvunzo kana zvinonetsa nekukurumidza. Vanofanirawo kupa rubatsiro rwehunyanzvi kune vatengi vavo kuti vaone kuti chigadzirwa chinoshandiswa nemazvo uye nemazvo.

Mukupedzisa, HEC chinhu chakakosha mumaindasitiri mazhinji, uye yakanakisa HEC mugadziri anoita basa rakakosha mukugadzira nekugovera chigadzirwa ichi. Vanofanirwa kunge vaine zvivakwa zvemazuva ano uye zvekushandisa, hunyanzvi hwehunyanzvi, uye kuzvipira kumhando uye kusimba. Nekupa chigadzirwa chemhando yepamusoro uye basa rakanakisa revatengi, vagadziri veHEC vanogona kubatsira vatengi vavo kubudirira mukushandisa kwavo.
