Ingcaciso yeMveliso:
I-Hydroxyethyl cellulose (HEC) ngumgubo omhlophe okanye okhanyayo, ongenavumba, ongenatyhefu. Ilungiswa ukusuka kwisiseko se-cellulose kunye ne-ethylene oxide (okanye i-chloroethane) nge-etherification. Yi-ether ye-cellulose enyibilikayo engekho-ionic. Ngenxa yokuba i-HEC cellulose ineempawu ezintle zokuqina, ukumiswa, ukusabalalisa, i-emulsification, i-adhesion, ukubunjwa kwefilimu, ukukhuselwa kokufuma, kunye nokukhuselwa kwe-colloids, isetyenziswa ngokubanzi kwi-petroleum extraction, i-coatings, ukwakhiwa, amayeza kunye nokutya, iingubo, ukwenza iphepha, kunye amanye amasimi.
Isicelo:
1. I-Hydroxyethyl cellulose powder ingachithwa emanzini ashushu kunye nabandayo, kwaye ayiyi kunyuka xa ishushu okanye ibilisiwe. Ngenxa yoko, inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity kunye ne-non-thermogelability.
2. I-HEC inokuhlalisana nezinye iipholima ezinyibilikayo emanzini, ii-surfactants, kunye neetyuwa. I-HEC yinto egqwesileyo ye-colloidal thickener equlethe izisombululo eziphezulu ze-dielectric.
3. Umthamo wayo wokugcinwa kwamanzi uphindwe kabini ngaphezu kwe-methylcellulose, kwaye unolawulo oluhle lokuhamba.
4. Xa kuthelekiswa ne-methylcellulose kunye ne-hydroxypropylmethylcellulose, i-HEC inamandla amakhulu okukhusela i-colloid.
Ishishini loKwakha: I-HEC ingasetyenziswa njenge-arhente yokugcina ukufuma kunye ne-sement inhibitor.
Umzi-mveliso woKwemba i-oyile: Ingasetyenziswa njengento ejiyayo kunye ne-samente ye-oyile yolwelo olusebenzayo. I-drilling fluid kunye ne-HEC inokuphucula ngokufanelekileyo ukuzinza kwe-drilling ngokusekelwe kumsebenzi wayo ophantsi oqinileyo.
Umzi-mveliso wokugquma: I-HEC inokudlala indima ekujikeni, emulsifying, ekusasazeni, ekuzinziseni nasekugcineni amanzi kwimathiriyeli yelatex. Ibonakaliswa yimpembelelo ebalulekileyo yokuqina, ukusasazeka kombala okulungileyo, ukubunjwa kwefilimu, kunye nokuzinza kokugcinwa.
Iphepha kunye ne-Inki: Ingasetyenziswa njenge-agent yokulinganisa kwiphepha kunye nebhodi lephepha, njengento yokuqinisa kunye nokuxhoma i-inki esekelwe emanzini.
Imichiza yemihla ngemihla: I-HEC yinto esebenzayo yokwenza ifilimu, i-adhesive, thickener, stabilizer kunye ne-dispersant kwiishampu, izilungisi zeenwele, kunye nezithambiso.
Iphakheji: 25 kgs / ibhegi okanye njengoko ucela.
Ugcino: Gcina kwindawo engenamoya, eyomileyo.
Imigangatho ephunyeziweyo: iMigangatho yeHlabathi.
