Iimveliso
I-Hydroxy ethyl cellulose (HEC)
I-HEC Imhlophe ukuya kobutyheli okanye ifibrous eqinileyo, ayinatyhefu, ayinancasa kwaye iyanyibilika emanzini.Ukunganyibiliki kwizinyibilikisi eziqhelekileyo eziphilayo.Ukuba neempawu ezifana nokujiya, ukumisa, ukuncamathelisa, ukumilisela, ukusabalalisa, ukubamba amanzi.Uluhlu oluhlukeneyo lwe-viscosity yesisombululo lunokulungiswa.Ukuba netyuwa enyibilikayo kwi-electrolyte. Isetyenziswa njengezinto zokuncamathelisa, i-surfactants, izikhuseli ze-colloidal, i-disperpersants, i-emulsifiers kunye nezinzinzi zokusasazeka. Isetyenziswa kakhulu ekugqumeni, kwi-inki yokuprinta, ifayibha, ukudaya, ukwenza iphepha, izithambiso, izibulali zinambuzane, ukusetyenzwa kweeminerali, ioyile. ukuchacha kunye neyeza.
Ukusebenza kwemveliso
1. I-HEC esetyenziselwa ukuqhekeza indlela yokukhupha i-polymerized dispersing agents ezifana ne-oil base water base gel fracturing fluid, i-polystyrene kunye ne-polyvinyl chloride.Kwakhona kwi-arhente yokuqina kwe-latex kushishino lwepeyinti, i-hygristor kwishishini le-elektroniki, i-agent ye-samente echasene ne-coagulant kunye ne-arhente yokugcina amanzi kushishino lokwakha.Ukucwenga kwishishini le-ceramic kunye ne-toothpaste binder.Ikwasetyenziswa ngokubanzi kwimiba emininzi njengokuprinta kunye nokudaya, amalaphu, iphepha, amayeza, impilo, ukutya, imidiza, izibulali-zinambuzane kunye nearhente yokucima umlilo.
2. Isetyenziswa njenge-water-based drilling fluids, kunye ne-ejenti yokuqina kunye nesinciphisi sokuhluza ulwelo olugqityiweyo, i-ajenti yokuqina inefuthe elicacileyo kwi-brine drilling fluid.Kananjalo ingasetyenziselwa ukuhluza i-filtrate ye-oyile yesamente yequla.Ukudibanisa kunye ne-polyvalent metal ion kwi-gel.3. Njengama-surfactants, i-colloids ekhuselayo, i-emulsion stabilizers ngokudibanisa ne-emulsion efana ne-vinyl chloride, i-vinyl acetate emulsion, kunye ne-tackifier, i-dispersant, i-dispersion stabilizer ye-emulsion.Isetyenziswa kakhulu kwimiba emininzi efana neengubo, iifayibha, ukudaya, iphepha, izithambiso, amayeza, izibulali-zinambuzane.Zininzi izinto ezisetyenziswayo ekusetyenzisweni kwe-oyile nakwishishini loomatshini.
4. Njengama-surfactants, i-agent ye-latex thickening, i-colloid ekhuselayo, i-oyile yokusetyenziswa kwe-fracturing fluid kunye ne-polystyrene kunye ne-polyvinyl chloride dispersing agents, njl.
