Iimpawu eziphambili ze-hydroxyethyl cellulose kukuba iyanyibilika emanzini abandayo namanzi ashushu, kwaye ayinazo iimpawu ze-gelling. Inoluhlu olubanzi lokutshintsha, ukunyibilika kunye ne-viscosity. Isisombululo se-hydroxyethyl cellulose sinokwenza ifilimu ecacileyo, kwaye sineempawu zohlobo olungelulo lwe-ionic olungadibaniyo nee-ion kwaye luhambelana kakuhle.
①Ubushushu obuphezulu kunye nokunyibilika kwamanzi: Xa kuthelekiswa ne-methyl cellulose (MC), enyibilikayo kuphela emanzini abandayo, i-hydroxyethyl cellulose inokunyibilika emanzini ashushu okanye emanzini abandayo. Uluhlu olubanzi lweempawu zokunyibilika kunye ne-viscosity, kunye ne-gelation engashushu.
②Ukumelana netyuwa: Ngenxa yohlobo lwayo olungelulo lwe-ionic, inokuphila kunye nezinye iipolymers ezinyibilikayo emanzini, ii-surfactants kunye neetyuwa ezahlukeneyo. Ke ngoko, xa ithelekiswa ne-ionic carboxymethyl cellulose (CMC), i-hydroxyethyl cellulose inokumelana netyuwa okungcono.
③Ukugcinwa kwamanzi, ukulingana, ukwenza ifilimu: amandla ayo okugcina amanzi aphindwe kabini kune-methyl cellulose, inolawulo oluhle lokuhamba kwamanzi kunye nokwenza ifilimu kakuhle, ukunciphisa ukulahleka kolwelo, ukuxinana, kunye nokwabelana ngesondo kwe-colloid ekhuselayo.
Ukusetyenziswa kwe-hydroxyethyl cellulose
I-Hydroxyethyl cellulose yimveliso ye-cellulose ether enyibilikayo emanzini engeyiyo ionic, esetyenziswa kakhulu kwiingubo zokwakha, i-petroleum, i-polymerization ye-polymer, amayeza, ukusetyenziswa kwemihla ngemihla, iphepha kunye ne-inki, amalaphu, iiseramikhi, ulwakhiwo, ezolimo kunye namanye amashishini. Inemisebenzi yokuqina, ukubopha, ukuxuba, ukusasaza nokuzinzisa, kwaye inokugcina amanzi, yenze ifilimu kwaye inike isiphumo sokukhusela se-colloid. Inyibilika lula emanzini abandayo nasemanzini ashushu, kwaye inokubonelela ngesisombululo esinoluhlu olubanzi lwe-viscosity. Enye yee-ethers ze-cellulose ezikhawulezayo.
Ipeyinti yelatex e-1
I-Hydroxyethyl cellulose yeyona nto isetyenziswa kakhulu kwi-latex coatings. Ukongeza kwi-latex coatings eyomeleleyo, ingakwazi nokuxubha, ukusasaza, ukuzinzisa nokugcina amanzi. Ibonakaliswa yimpembelelo emangalisayo yokuqina, uphuhliso oluhle lombala, ipropati yokwenza ifilimu kunye nozinzo lokugcina. I-Hydroxyethyl cellulose yi-non-ionic cellulose derivative engasetyenziswa kuluhlu olubanzi lwe-pH. Ihambelana kakuhle nezinye izinto ezikwicandelo (ezifana nee-pigments, izongezo, izizalisi kunye neetyuwa). Ii-coatings ezijiyileyo nge-hydroxyethyl cellulose zine-rheology elungileyo kumanqanaba ahlukeneyo okucheba kwaye ziyi-pseudoplastic. Iindlela zokwakha ezifana nokubrasha, i-roller coating, kunye nokutshiza zingasetyenziswa. Ulwakhiwo oluhle, akukho lula ukuthontsiza, ukugoba kunye nokutshiza, kunye nokulinganisa okuhle.
2 Ukwenziwa kwePolymer
I-Hydroxyethyl cellulose inemisebenzi yokusasaza, ukuxuba, ukumisa nokuzinzisa kwiindawo ze-polymerization okanye ze-copolymerization zee-resin zokwenziwa, kwaye ingasetyenziswa njenge-colloid ekhuselayo. Ibonakaliswa ngamandla okusasaza aqinileyo, "ifilimu" encinci yamasuntswana, ubungakanani obuncinci bamasuntswana, imilo efanayo yamasuntswana, uhlobo olukhululekileyo, ukunyibilika okuhle, ukubonakala okuphezulu kwemveliso kunye nokucutshungulwa okulula. Ngenxa yokuba i-hydroxyethyl cellulose inokunyibilika emanzini abandayo nasemanzini ashushu, kwaye ayinalo iqondo lobushushu be-gelling, ifanelekile ngakumbi kwiimpendulo ezahlukeneyo ze-polymerization.
Iimpawu ezibalulekileyo zomzimba zokuphanda umgangatho we-dispersant kukuxinana komphezulu (okanye i-interfacial), amandla e-interfacial kunye nobushushu be-gelation yesisombululo sayo samanzi. Ezi mpawu ze-hydroxyethyl cellulose zifanelekile kwi-polymerization okanye i-copolymerization yee-resin zokwenziwa.
I-Hydroxyethyl cellulose ihambelana kakuhle nezinye ii-ethers ze-cellulose ezinyibilikayo emanzini kunye ne-PVA. Inkqubo edibeneyo eyenziwe ngolu hlobo inokufumana isiphumo esibanzi sokufunda kumandla omnye nomnye kunye nokufezekisa ubuthathaka bomnye. Iimveliso ze-resin edibeneyo azinamgangatho olungileyo kuphela, kodwa zikwanciphisa ukulahleka kwezinto.
Ukubhola ioyile oku-3
Kwi-oyile yokugrumba nokuvelisa ioyile, i-hydroxyethyl cellulose ene-viscosity ephezulu isetyenziswa kakhulu njenge-viscosifier yokugcwalisa ulwelo kunye nokugqiba ulwelo. I-hydroxyethyl cellulose ene-viscosity ephantsi isetyenziswa njengesinciphisi sokulahleka kolwelo. Kwiindidi ezahlukeneyo zodaka ezifunekayo ekugrumbeni, ekugqibeni, ekuqiniseni nasekuqhekekeni, i-hydroxyethyl cellulose isetyenziswa njengesithambisi ukuze kufunyanwe ukugeleza okuhle kunye nokuzinza kodaka. Ngexesha lokugrumba, inokuphucula amandla okuthwala isanti yodaka kwaye yandise ubomi benkonzo ye-drill bit. Kwiindidi zokugqiba ulwelo oluqinileyo oluphantsi kunye nolwelo lokuqinisa, iipropati ezilungileyo zokunciphisa ukulahleka kwamanzi ze-hydroxyethyl cellulose zinokuthintela amanzi amaninzi ukuba angangeni kwi-oyile yodaka, kwaye inokuphucula amandla okuvelisa kwi-oyile yodaka.
4 Iikhemikhali zemihla ngemihla
