Iimpawu eziphambili ze-hydroxyethyl cellulose kukuba i-soluble emanzini abandayo kunye namanzi ashushu, kwaye ayinayo i-gelling properties. Inoluhlu olubanzi lwedigri yokutshintsha, ukunyibilika kunye ne-viscosity. imvula. Isisombululo se-cellulose se-Hydroxyethyl sinokwenza ifilimu ecacileyo, kwaye ineempawu zohlobo olungenayo i-ionic olungahambelani ne-ion kwaye luhambelana kakuhle.
①Ubushushu obuphezulu kunye nokunyibilika kwamanzi: Xa kuthelekiswa ne-methyl cellulose (MC), enyibilika kuphela kumanzi abandayo, i-hydroxyethyl cellulose inokunyibilika emanzini ashushu okanye abandayo. Uluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engekho-thermal.
②Ukumelana netyuwa: Ngenxa yohlobo lwayo olungenayo i-ionic, luyakwazi ukuhlala kunye nezinye iipolymers ezinyibilikayo zamanzi, i-surfactants kunye neetyuwa kuluhlu olubanzi. Ke ngoko, xa kuthelekiswa ne-ionic carboxymethyl cellulose (CMC), i-hydroxyethyl cellulose inokumelana ngcono netyuwa.
③ Ukugcinwa kwamanzi, ukulinganisa, ukwenza ifilimu: amandla okugcina amanzi aphindwe kabini kune-methyl cellulose, kunye nolawulo oluhle kakhulu lokuhamba kunye nokwenza ifilimu egqwesileyo, ukunciphisa ilahleko yolwelo, ukungahambi kakuhle, isondo esikhuselayo se-colloid.
Ukusetyenziswa kwe-hydroxyethyl cellulose
I-cellulose ye-Hydroxyethyl yimveliso ye-cellulose e-ether engekho i-ionic yamanzi, esetyenziswa ngokubanzi kwi-architectural coatings, i-petroleum, i-polymerization, iyeza, ukusetyenziswa kwansuku zonke, iphepha kunye ne-inki, amalaphu, i-ceramics, ukwakhiwa, ezolimo kunye namanye amashishini. Inemisebenzi yokuqina, ukudibanisa, i-emulsifying, ukusabalalisa kunye nokuzinzisa, kwaye inokugcina amanzi, ukwenza ifilimu kunye nokubonelela ngempembelelo ye-colloid yokukhusela. I-soluble ngokulula emanzini abandayo kunye namanzi ashushu, kwaye inokubonelela ngesisombululo esinoluhlu olubanzi lwe-viscosity. Enye yee-ether ze-cellulose ezikhawulezayo.
Ipeyinti ye-latex eyi-1
I-Hydroxyethyl cellulose sesona sityebi sisetyenziswa kakhulu kwiingubo zelatex. Ukongeza kwiingubo zelatex ezityebileyo, inokuphinda ifake, isasaze, izinze kwaye igcine amanzi. Ibonakaliswa yimpembelelo ephawulekayo yokuqina, ukuphuhliswa kakuhle kombala, ipropati yokwenza ifilimu kunye nokuzinza kokugcina. I-Hydroxyethyl cellulose yi-non-ionic cellulose derivative enokusetyenziswa kuluhlu olubanzi lwe-pH. Inokuhambelana kakuhle nezinye izinto ezikwicandelo (ezifana nee-pigments, i-additives, iifayili kunye neetyuwa). Iingubo ezijiyile nge-hydroxyethyl cellulose zinerheology elungileyo kumazinga ahlukeneyo okucheba kwaye ziyi-pseudoplastic. Iindlela zokwakha ezifana nokuxubha, ukugquma ngerola, kunye nokutshiza zinokusetyenziswa. Ulwakhiwo oluhle, akukho lula ukuthontsiza, ukugoba kunye nokuchaphaza, kunye nomgangatho olungileyo.
2 Ukwenziwa kwePolymerization
I-Hydroxyethyl cellulose inemisebenzi yokusabalalisa, i-emulsifying, ukumisa kunye nokuzinzisa kwi-polymerization okanye i-copolymerization components of synthetic resins, kwaye ingasetyenziselwa njenge-colloid ekhuselayo. Ibonakala ngobuchule obunamandla bokusasaza, "ifilimu" encinci yamasuntswana, ubungakanani bamasuntswana alungileyo, imilo yamasuntswana afanayo, uhlobo oluxekethileyo, ulwelo olulungileyo, ukucaca okuphezulu kwemveliso kunye nokusebenza ngokulula. Ngenxa yokuba i-hydroxyethyl cellulose inokunyibilika emanzini abandayo kunye namanzi ashushu, kwaye ayinayo indawo yokushisa ye-gelling, ifaneleka ngakumbi kwiimpendulo ezahlukeneyo ze-polymerization.
Iimpawu ezibalulekileyo zomzimba zokuphanda umgangatho we-dispersant yi-tension (okanye i-interfacial) yoxinzelelo, amandla okudibanisa ubuso kunye nobushushu be-gelation yesisombululo sayo samanzi. Ezi mpawu ze-hydroxyethyl cellulose zifanelekile kwi-polymerization okanye i-copolymerization ye-synthetic resins.
Iselulosi ye-Hydroxyethyl inokuhambelana kakuhle nezinye ii-ether ze-cellulose ezinyibilikayo emanzini kunye ne-PVA. Inkqubo edibeneyo eyenziweyo inokufumana isiphumo esibanzi sokufunda kumandla omnye nomnye kunye nokuhambelana nobuthathaka bomntu. Iimveliso ze-resin ezihlanganisiweyo azikho nje umgangatho omhle, kodwa zinciphisa ukulahleka kwezinto.
I-3 yokomba ioli
Kwi-oyile yokugaya kunye nemveliso, i-high-viscosity hydroxyethyl cellulose isetyenziswa kakhulu njenge-viscosifier yokugqiba ulwelo kunye nokugqiba ulwelo. I-viscosity ephantsi ye-hydroxyethyl cellulose isetyenziswa njengokunciphisa ukulahlekelwa kwamanzi. Kwiidaka ezahlukeneyo ezifunekayo ekusebenzeni, ukugqitywa, ukufakwa kwe-cementing kunye nokuqhekeka, i-hydroxyethyl cellulose isetyenziswa njenge-thickener yokufumana umbane olungileyo kunye nokuzinza kodaka. Ngexesha lokugaya, kunokuphucula umthamo wokuthwala isanti kunye nokwandisa ubomi benkonzo ye-drill bit. Kwinqanaba elisezantsi lokugqibezela ulwelo kunye nolwelo lwesamente, iipropathi ezigqwesileyo zokunciphisa ilahleko yamanzi ye-hydroxyethyl cellulose inokuthintela ubuninzi bamanzi ukuba bungene kumaleko we-oyile ukusuka eludakeni, kwaye inokuphucula amandla okuvelisa i-oyile.
4 Ikhemikhali yemihla ngemihla
I-Hydroxyethylcellulose yifilimu esebenzayo yangaphambili, i-binder, i-thickener, i-stabilizer kunye ne-dispersant kwii-shampoos, izitshizi zeenwele, i-neutralizers, i-conditioner kunye ne-cosmetics; kwi-detergent powders Yi-arhente yokubuyisela ukungcola. I-Hydroxyethyl cellulose ichitheka ngokukhawuleza kwiqondo lokushisa eliphezulu, elinokukhawuleza inkqubo yokuvelisa kunye nokuphucula ukusebenza kakuhle kwemveliso. Isici esicacileyo se-detergents equkethe i-hydroxyethyl cellulose kukuba inokuphucula ukugudiswa kunye ne-mercerization yamalaphu.
5 uyilo
Iselulosi yeHydroxyethyl ingasetyenziswa kwiimveliso zokwakha ezifana nemixube yekhonkrithi, udaka olutsha, udaka lwegypsum okanye olunye udaka, njl., ukugcina amanzi ngexesha lokwakha phambi kokuba zisete kwaye ziqine. Ukongeza ekuphuculeni ukugcinwa kwamanzi kwimveliso yokwakha, i-hydroxyethyl cellulose inokwandisa ixesha lokulungiswa kunye nexesha elivulekileyo le-stucco okanye i-mastic. Yehlisa ulusu, ukutyibilika kunye nokuncipha. Oku kunokuphucula ukusebenza kolwakhiwo, ukuphucula ukusebenza kakuhle, ukonga ixesha, kwaye kwangaxeshanye kunyuse izinga lokwandiswa kwevolumu ye-stucco, ngaloo ndlela kugcinwe imathiriyeli ekrwada.
6 ezolimo
I-Hydroxyethyl cellulose isetyenziselwa i-emulsion ye-pesticide kunye ne-suspension formulations njenge-thickener ye-emulsions yokutshiza okanye ukumiswa. Inokunciphisa ukukhukuliseka kwe-arhente kwaye iyenze ibambelele ngokuqinileyo emagqabini esityalo, ngaloo ndlela ikhulise umphumo wokutshiza kwe-foliar. Iselulosi yeHydroxyethyl inokusetyenziswa njengesixhobo sokwenza ifilim kwimbewu yokugquma kunye ne-agent yokwambathisa; njenge-binder kunye ne-ejenti yokwenza ifilimu ekuhlaziyweni kwamagqabi ecuba.
7 Iphepha kunye ne-Inki
Iselulosi yeHydroxyethyl ingasetyenziswa njengesixhobo sokulinganisa ephepheni nasebhodini nanjengesixhobo sokujiya nokuxhoma kwii-inki ezisekwe emanzini. Kwinkqubo yokwenza iphepha, iipropati eziphezulu ze-hydroxyethyl cellulose ziquka ukuhambelana neentsini ezininzi, i-resin kunye ne-salts ye-inorganic, i-foaming ephantsi, ukusetyenziswa kwe-oksijeni ephantsi kunye nokukwazi ukwenza ifilimu epholileyo. Ifilimu inomgangatho ophantsi wokungena kunye neglosi eyomeleleyo, kwaye inokunciphisa iindleko. Iphepha elilingana ne-hydroxyethyl cellulose loshicilelo olukumgangatho ophezulu. Xa kusenziwa i-inki esekwe emanzini, i-inki esekwe emanzini ejiyelwe nge-hydroxyethyl cellulose yoma ngokukhawuleza, inombala oqaqambileyo, kwaye ayivelisi ukuncamathelisa.
8 ilaphu
Ingasetyenziswa njenge-binder kunye ne-ejenti yokulinganisa kushicilelo lwelaphu kunye nokuncamathisela okudayayo kunye nepeyinti yelatex; ityezi yokulinganisa imathiriyeli ngasemva kwikhaphethi. Kwifiber yeglasi, isetyenziswa njenge-ejenti yokubumba kunye ne-binder; kwipulp yesikhumba, ingasetyenziswa njengesilungisi kunye nesibophelelo.
