Ukusetyenziswa kweHydroxyethyl Cellulose (HEC)

I-Hydroxyethyl cellulose (HEC)yi-non-ionic cellulose ether eyenziwe nge-cellulose yendalo yepolymer ngokusebenzisa uthotho lwe-etherification. Yipowder emhlophe okanye i-granule engenavumba, engenancasa, engenatyhefu, enokuchithwa emanzini abandayo ukuze yenze isisombululo esicacileyo esixineneyo, kwaye ukunyibilika akuchaphazeleki lixabiso le-pH. Ine-thickening, binding, dispersing, emulsifying, film-forming, suspending, absorbing, surface active, moisturizing and salty-resistant. Isetyenziswa kakhulu kwipeyinti, ekwakheni, kwilaphu, kwiikhemikhali zemihla ngemihla, ephepheni, ekubholeni ioyile nakwamanye amashishini.

Iindawo eziphambili zesicelo:

1. Ipeyinti: Ipeyinti esekwe emanzini lulwelo oluqinileyo oluqulunqwe ngezinyibilikisi zendalo okanye amanzi asekelwe kwi-resin, okanye ioyile, okanye i-emulsion, kunye nokongezwa kwezongezo ezifanelekileyo. Iipeyinti ezisekwe emanzini ezisebenza kakuhle kufuneka zibe nokusebenza kakuhle, amandla okufihla kakuhle, ukunamathela okuqinileyo kwepeyinti, kunye nokusebenza kakuhle kokugcina amanzi; i-cellulose ether yeyona nto ifanelekileyo yokubonelela ngezi mpawu.

2. Ulwakhiwo: Kwicandelo loshishino lokwakha, i-HEC isetyenziswa njengesongezelelo sezinto ezifana nezinto zodonga, ikhonkrithi (kuquka i-asphalt), iithayile ezincamathelisiweyo kunye nezinto zokubopha, ezinokunyusa ukutyeba kunye nokuqina kwezixhobo zokwakha, ziphucule ukunamathela, ukutyeba, kunye nokugcinwa kwamanzi. Yonyusa amandla okuguquguquka kweendawo okanye izinto, iphucule ukushwabana, kwaye iphephe imingxunya yomphetho.

3.Iimpahla zomqhaphu: Umqhaphu, iifayibha zokwenziwa okanye imixube ephethwe yiHEC iphucula iipropati zayo ezifana nokumelana nokurhawuzelelwa, ukudaya, ukumelana nomlilo kunye nokumelana namabala, kunye nokuphucula ukuzinza kwemizimba yazo (ukushwabana) kunye nokuqina, ngakumbi kwiifayibha zokwenziwa, ezenza zikwazi ukuphefumla kwaye zinciphise umbane ongashukumiyo.

4. Iikhemikhali zemihla ngemihla: I-Cellulose ether sisongezelelo esibalulekileyo kwiimveliso zeekhemikhali zemihla ngemihla. Ayinakuphucula kuphela i-viscosity yezinto zokuthambisa ezingamanzi okanye ze-emulsion, kodwa ikwaphucula nokusabalalisa kunye nozinzo lwe-foam.

5. Iphepha: Kwicandelo lokwenza iphepha, i-HEC ingasetyenziswa njengearhente yokulinganisa ubungakanani, iarhente yokuqinisa kunye nokuguqula iphepha.

6. Ukugrumba ioyile：I-HEC isetyenziswa kakhulu njengearhente yokutyeba nokuzinzisa kwinkqubo yonyango lwe-oyile. Yikhemikhali elungileyo ye-oyile. Yayisetyenziswa kakhulu ekugrumbeni, ekugqityweni kwemithombo, ekufakeni isamente nakwezinye iinkqubo zokuvelisa ioyile kumazwe angaphandle ngeminyaka yoo-1960.

Ezinye iinkalo zesicelo:

I-HECingadlala indima yokuncamathisela ityhefu kumagqabi kwimisebenzi yokutshiza; i-HEC ingasetyenziselwa ukujiya kwi-emulsions yokutshiza ukunciphisa ukutyibilika kwamayeza, ngaloo ndlela yonyusa isiphumo sokutshiza kwamagqabi. I-HEC ingasetyenziselwa njengearhente yokwenza ifilimu kwiiarhente zokugquma imbewu; njengesibopheleli ekusetyenzisweni kwakhona kwamagqabi ecuba. I-Hydroxyethyl cellulose ingasetyenziselwa njengesongezelelo sokwandisa ukusebenza kokugquma kwezinto ezingatshiyo, kwaye isetyenzisiwe kakhulu ekulungiseleleni "iziqinisi ezitshiyo". I-Hydroxyethyl cellulose inokuphucula amandla amanzi kunye nokuncitshiswa kwesanti yesamente kunye neenkqubo zesanti ye-sodium silicate. I-Hydroxyethyl cellulose ingasetyenziselwa ukuvelisa iifilimu kunye nesinyibilikisi ekuveliseni iislayidi ezincinci. Isinyibilikisi kwiilwelo ezinetyuwa eninzi esetyenziswa ekucutshungulweni kwefilimu. Isetyenziswa njengesibopheleli kunye nesinyibilikisi esizinzileyo kwiiarhente ze-fluorescent kwiingubo zetyhubhu ze-fluorescent. Ingakhusela i-colloid kwimpembelelo yoxinzelelo lwe-electrolyte; i-hydroxyethyl cellulose inokukhuthaza ukufakwa okufanayo kwisisombululo se-cadmium plating. Ingasetyenziselwa ukwenza izibopheleli ezinamandla aphezulu kwiiseramikhi. Izinto ezithintela amanzi zithintela ukufuma ukuba kungangeni kwiintambo ezonakeleyo.
