Izakhiwo eziyinhloko ze-hydroxyethyl cellulose ukuthi inyibilika emanzini abandayo namanzi ashisayo, futhi ayinazo izakhiwo ze-gelling.Inezinhlobonhlobo eziningi ze-substitution degree, i-solubility kanye ne-viscosity.imvula.Isixazululo se-Hydroxyethyl cellulose singakha ifilimu esobala, futhi sinezici zohlobo olungezona i-ionic olungasebenzisani nama-ion futhi olunokuhambisana okuhle.
① Izinga lokushisa eliphezulu nokuncibilika kwamanzi: Uma kuqhathaniswa ne-methyl cellulose (MC), encibilika kuphela emanzini abandayo, i-hydroxyethyl cellulose ingancibilika emanzini ashisayo noma emanzini abandayo.Uhlu olubanzi lwezakhiwo ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi.
②Ukumelana nosawoti: Ngenxa yohlobo lwayo olungeyona i-ionic, ingahlala namanye ama-polymers ancibilika emanzini, ama-surfactants nosawoti ebangeni elibanzi.Ngakho-ke, uma iqhathaniswa ne-ionic carboxymethyl cellulose (CMC), i-hydroxyethyl cellulose inokumelana nosawoti okungcono.
③Ukugcinwa kwamanzi, ukulinganisa, ukwenza ifilimu: amandla ayo okugcina amanzi aphindwe kabili kune-methyl cellulose, enomthetho omuhle kakhulu wokugeleza nokwenza ifilimu okuhle kakhulu, ukuncipha kokulahlekelwa uketshezi, ukungezwani, ucansi oluvikelayo lwe-colloid.
Ukusetshenziswa kwe-hydroxyethyl cellulose
I-Hydroxyethyl cellulose ingumkhiqizo we-cellulose we-cellulose we-non-ionic oncibilika emanzini, osetshenziswa kabanzi ekwakhiweni kwezakhiwo, i-petroleum, i-polymerization, imithi, ukusetshenziswa kwansuku zonke, iphepha noyinki, izindwangu, izitsha zobumba, ukwakhiwa, ezolimo kanye nezinye izimboni.Inemisebenzi yokuqina, ukubopha, ukufaka i-emulsifying, ukuhlakazeka nokuzinzisa, futhi ingagcina amanzi, yakha ifilimu futhi inikeze umphumela we-colloid ovikelayo.Incibilika kalula emanzini abandayo nasemanzini ashisayo, futhi inganikeza isisombululo ngezinhlobonhlobo ze-viscosity.Enye ye-cellulose ethers esheshayo.
1 upende we-latex
I-Hydroxyethyl cellulose iyi-thickener esetshenziswa kakhulu ezimbotsheni ze-latex.Ngaphezu kokuqina kwezingubo ze-latex, ingaphinda ifake, ihlakaze, izinze futhi igcine amanzi.Ibonakala ngomphumela wokuqina okuphawulekayo, ukuthuthukiswa kombala omuhle, indawo yokwenza ifilimu nokuzinza kwesitoreji.I-Hydroxyethyl cellulose iwukuphuma kwe-non-ionic cellulose engasetshenziswa ku-pH ebanzi.Inokuhambisana okuhle nezinye izinto ezisengxenyeni (ezifana nezingulube, izithasiselo, izigcwalisi nosawoti).Izingubo ezijiywe nge-hydroxyethyl cellulose zine-rheology enhle ngamanani ahlukahlukene wokugunda futhi ziyi-pseudoplastic.Izindlela zokwakha ezifana nokuxubha, ukumboza nge-roller, nokufutha zingasetshenziswa.Ukwakhiwa okuhle, akulula ukuconsa, ukucwila nokuchaphaza, nokuhleleka okuhle.
2 I-Polymerization
I-Hydroxyethyl cellulose inemisebenzi yokuhlakaza, yokufaka emulsifying, ukumisa okwesikhashana kanye nokuzinzisa ezingxenyeni ze-polymerization noma i-copolymerization yama-synthetic resins, futhi ingasetshenziswa njenge-colloid evikelayo.Ibonakala ngekhono eliqinile lokuhlakazeka, "ifilimu" encane yezinhlayiya, usayizi wezinhlayiyana ezincane, ukwakheka kwezinhlayiyana ezifanayo, uhlobo oluxekethile, uketshezi oluhle, ukukhanya komkhiqizo ophezulu kanye nokucubungula okulula.Ngenxa yokuthi i-hydroxyethyl cellulose ingancibilika emanzini abandayo nasemanzini ashisayo, futhi ayinayo indawo yokushisa ye-gelling, ifaneleka kakhulu ukusabela okuhlukahlukene kwe-polymerization.
Izakhiwo ezibalulekile zomzimba zokuphenya ikhwalithi ye-dispersant yi-surface (noma i-interface) ukungezwani, amandla ahlangene nokushisa kwe-gelation yesisombululo sayo esinamanzi.Lezi zakhiwo ze-hydroxyethyl cellulose zilungele ukwenziwa kwe-polymerization noma i-copolymerization yama-synthetic resins.
I-Hydroxyethyl cellulose inokuhambisana okuhle namanye ama-cellulose ethers ancibilika emanzini kanye ne-PVA.Uhlelo oluyinhlanganisela olwakhiwe kanjalo lungathola umphumela ophelele wokufunda emandleni omunye nomunye kanye nokuphelelisa ubuthakathaka bomuntu.Imikhiqizo ye-resin ehlanganisiwe ayinayo kuphela ikhwalithi enhle, kodwa futhi inciphisa ukulahlekelwa kwezinto ezibonakalayo.
3 ukugaya amafutha
Ekubhobololweni kukawoyela nasekukhiqizeni, i-high-viscosity hydroxyethyl cellulose isetshenziswa kakhulu njenge-viscosifier yokuqedela uketshezi kanye noketshezi lokuqeda.I-viscosity ephansi ye-hydroxyethyl cellulose isetshenziswa njengesinciphisi sokulahlekelwa uketshezi.Emadakeni ahlukahlukene adingekayo ukuze kubhobozwe, kuqedwe, kufakwe usimende kanye nokusebenza kwe-fracturing, i-hydroxyethyl cellulose isetshenziswa njenge-thickener ukuthola uketshezi oluhle nokuzinza kodaka.Ngesikhathi sokumba, ingathuthukisa umthamo wokuthwala isihlabathi sodaka futhi yandise impilo yesevisi ye-drill bit.Emanzini aphansi okuphothula isigaba esiqinile kanye noketshezi lukasimende, izakhiwo ezinhle kakhulu zokunciphisa ukulahlekelwa kwamanzi kwe-hydroxyethyl cellulose zingavimbela inani elikhulu lamanzi ukuthi lingangeni ungqimba lwamafutha odakeni, futhi lingathuthukisa amandla okukhiqiza ungqimba lwamafutha.
4 Ikhemikhali yansuku zonke
I-Hydroxyethylcellulose iyifilimu ephumelelayo yangaphambili, i-binder, thickener, stabilizer kanye ne-dispersant kuma-shampoos, izifutho zezinwele, ama-neutralizers, ama-conditioner kanye nezimonyo;kuma-detergent powders Kuyi-ejenti yokufaka kabusha ukungcola.I-Hydroxyethyl cellulose incibilika ngokushesha ekushiseni okuphezulu, okungasheshisa inqubo yokukhiqiza futhi kuthuthukise ukusebenza kahle kokukhiqiza.Isici esisobala sezinto zokuhlanza eziqukethe i-hydroxyethyl cellulose ukuthi zingathuthukisa ukushelela kanye ne-mercerization yezindwangu.
5 izakhiwo
I-Hydroxyethyl cellulose ingasetshenziswa emikhiqizweni yokwakha efana nezingxube zikakhonkolo, udaka olusha, ukhonkolo lwe-gypsum noma olunye udaka, njll., ukugcina amanzi ngesikhathi sokwakha ngaphambi kokuthi kusethwe futhi kuqine.Ngaphezu kokuthuthukisa ukugcinwa kwamanzi emikhiqizweni yokwakha, i-hydroxyethyl cellulose ingase futhi yelule ukulungiswa kanye nesikhathi esivulekile se-stucco noma i-mastic.Yehlisa ukucwila, ukushelela kanye nokuwohloka.Lokhu kungathuthukisa ukusebenza komsebenzi wokwakha, kuthuthukise ukusebenza kahle komsebenzi, konga isikhathi, futhi ngesikhathi esifanayo kwandise izinga lokunwetshwa kwevolumu ye-stucco, ngaleyo ndlela kulondoloze izinto ezingavuthiwe.
6 ezolimo
I-Hydroxyethyl cellulose isetshenziswa ku-emulsion yesibulala-zinambuzane kanye nokwakhiwa kokumiswa njenge-thickener ye-spray emulsions noma ukumiswa.Inganciphisa ukukhukhuleka kwe-ejenti futhi iyenze inamathele ngokuqinile emaqabunga esitshalo, ngaleyo ndlela yandise umphumela wokufafaza kwe-foliar.I-Hydroxyethyl cellulose ingasetshenziswa futhi njenge-ejenti eyenza ifilimu ekuhlanganiseni imbewu kanye ne-ejenti yokuhlanganisa;njenge-binder kanye ne-ejenti eyenza ifilimu ekugayweni kabusha kwamaqabunga kagwayi.
7 Iphepha Noyinki
I-Hydroxyethyl cellulose ingasetshenziswa njenge-ejenti yokulinganisa ephepheni nasebhodini nanjenge-ejenti ejiyayo nelengayo kumayinki asekelwe emanzini.Enqubweni yokwenza iphepha, izakhiwo eziphakeme ze-hydroxyethyl cellulose zihlanganisa ukuhambisana nezinsini eziningi, ama-resin kanye nosawoti we-inorganic, amagwebu aphansi, ukusetshenziswa okuphansi kwe-oxygen kanye nekhono lokwenza ifilimu elibushelelezi elingaphezulu.Ifilimu inokungena okuphansi kwendawo kanye nokucwebezela okuqinile, futhi inganciphisa nezindleko.Iphepha elinosayizi we-hydroxyethyl cellulose wokuphrinta kwekhwalithi ephezulu.Ekwenziweni kukayinki osuselwe emanzini, uyinki osuselwe emanzini ogqinsiswe nge-hydroxyethyl cellulose yoma ngokushesha, unombala omuhle wokusabalalisa, futhi awukhiqizi ukunamathela.
8 indwangu
Ingasetshenziswa njenge-binder kanye ne-ejenti yokulinganisa ekuphrinteni kwendwangu kanye nokunamathisela kokudaya nopende we-latex;i-thickener yokulinganisa impahla ngemuva kukhaphethi.Ku-glass fiber, isetshenziswa njenge-ejenti yokubumba kanye ne-binder;ku-pulp yesikhumba, ingasetshenziswa njenge-modifier ne-binder.Ihlinzeka ngebanga elibanzi le-viscosity lalezi zimbotshana noma izinto zokunamathisela, okuholela ekulungisweni okufanayo nokushesha kwe-coating kanye nokucaciswa okuthuthukisiwe kokuphrinta.
9 izitsha zobumba
Isibopho esinamandla aphezulu sokwenza izitsha zobumba.
10 umuthi wokuxubha
Ingasetshenziswa njenge-thickener ekwenzeni umuthi wokuxubha.
