Ukusetshenziswa kwe-Hydroxyethyl Cellulose (HEC)

I-Hydroxyethyl cellulose (HEC)iyi-non-ionic cellulose ether eyenziwe nge-cellulose yemvelo ye-polymer ngokusebenzisa uchungechunge lwe-etherification. Iyimpuphu emhlophe noma i-granule engenaphunga, engenambitheki, engenabuthi, engancibilikiswa emanzini abandayo ukuze yakhe isixazululo esibonakalayo esiqinile, futhi ukuncibilika akuthinteki yinani le-pH. Inezakhiwo zokujiya, zokubopha, zokuhlakaza, zokuhlanganisa, zokwakha ifilimu, zokumiswa, zokwamukela, ezisebenzayo ebusweni, zokugcina umswakama kanye nokumelana nosawoti. Isetshenziswa kabanzi ependeni, ekwakheni, ezindwangu, emakhemikhali ansuku zonke, ephepheni, ekubholeni uwoyela nakwezinye izimboni.

Izindawo eziyinhloko zohlelo lokusebenza:

1. Upende: Upende osekelwe emanzini uketshezi oluqinile olwakhiwe ngezithako eziphilayo noma amanzi asekelwe ku-resin, noma uwoyela, noma i-emulsion, kanye nokwengezwa kwezithako ezifanele. Izimbozo ezisekelwe emanzini ezisebenza kahle kakhulu kufanele futhi zibe nokusebenza okuhle kakhulu, amandla amahle okufihla, ukunamathela okuqinile kokumboza, kanye nokusebenza okuhle kokugcina amanzi; i-cellulose ether iyinto eluhlaza efanelekile kakhulu ukunikeza lezi zakhiwo.

2. Ukwakhiwa: Emkhakheni wezokwakha, i-HEC isetshenziswa njengesithasiselo sezinto ezifana nezinto zodonga, ukhonkolo (kufaka phakathi i-asphalt), amathayili anamathelisiwe nezinto zokubopha, okungakhulisa ukujiya nokuqina kwezinto zokwakha, kuthuthukise ukunamathela, ukuthambisa, kanye nokugcinwa kwamanzi. Khulisa amandla okuguquguquka kwezingxenye noma izingxenye, kuthuthukise ukushwabana, futhi kugweme ukuqhekeka komphetho.

3. Indwangu: Ukotini, imicu yokwenziwa noma izingxube eziphathwe nge-HEC zithuthukisa izakhiwo zazo njengokumelana nokuguguleka, ukudaya, ukumelana nomlilo kanye nokumelana namabala, kanye nokuthuthukisa ukuzinza komzimba wazo (ukuncipha) kanye nokuqina, ikakhulukazi imicu yokwenziwa, okwenza ziphefumuleke futhi zinciphise ugesi ongashintshi.

4. Amakhemikhali ansuku zonke: I-Cellulose ether iyisengezo esibalulekile emikhiqizweni yamakhemikhali yansuku zonke. Ayikwazi nje ukuthuthukisa i-viscosity yezimonyo eziwuketshezi noma ze-emulsion, kodwa futhi ithuthukisa ukuhlakazeka kanye nokuqina kwe-foam.

5. Iphepha: Emkhakheni wokwenza iphepha, i-HEC ingasetshenziswa njenge-ejenti yokulinganisa, i-ejenti yokuqinisa kanye ne-modifier yephepha.

6. Ukubhoboza uwoyela：I-HEC isetshenziswa kakhulu njenge-ejenti yokuqina nokuzinzisa enqubweni yokwelashwa kwensimu kawoyela. Iyikhemikhali enhle yensimu kawoyela. Yayisetshenziswa kabanzi ekubhobozeni, ekuqedeni imithombo, ekusimeni kanye neminye imisebenzi yokukhiqiza uwoyela emazweni angaphandle ngawo-1960.

Ezinye izinkambu zesicelo:

I-HECingadlala indima yokunamathela ubuthi emaqabungeni emisebenzini yokufafaza; i-HEC ingasetshenziswa njengesithambisi se-spray emulsions ukunciphisa ukugeleza kwemithi, ngaleyo ndlela yandise umphumela wokusetshenziswa kokufafaza ngamahlamvu. I-HEC ingasetshenziswa futhi njenge-ejenti yokwakha ifilimu kuma-ejenti okumboza imbewu; njengesithambisi ekusetshenzisweni kabusha kwamaqabunga kagwayi. I-Hydroxyethyl cellulose ingasetshenziswa njengesithambisi sokwandisa ukusebenza kokumboza kwezinto ezingashi, futhi isetshenziswe kabanzi ekulungiseleleni "ama-thickeners angashi". I-Hydroxyethyl cellulose ingathuthukisa amandla amanzi kanye nokuncibilika kwesihlabathi sikasimende kanye nezinhlelo zesihlabathi se-sodium silicate. I-Hydroxyethyl cellulose ingasetshenziswa ekukhiqizweni kwamafilimu kanye njengesithambisi ekukhiqizweni kwama-slide amancane. Isithambisi emanzini anokugcwala kukasawoti okuphezulu okusetshenziswa ekucutshungulweni kwamafilimu. Isetshenziswa njengesithambisi kanye nesithambisi esizinzile sama-ejenti e-fluorescent kuma-tube coating e-fluorescent. Ingavikela i-colloid ethonyeni lokugcwala kwe-electrolyte; i-hydroxyethyl cellulose ingakhuthaza ukufakwa okufanayo kusisombululo se-cadmium plating. Ingasetshenziswa ukwakha ama-binder anamandla aphezulu e-ceramics. Izinto ezixosha amanzi zivimbela umswakama ukuthi ungangeni ezintanjeni ezonakele.
