Ibanga likapende HEC
Ibanga likapendeI-HEC Hydroxyethyl cellulose iwuhlobo lwe-polymer engeyona i-ionic encibilika emanzini, impushana emhlophe noma ephuzi, ukugeleza kalula, engenaphunga futhi ayinambitheki, ingancibilika kuwo womabili amanzi abandayo nashisayo, futhi izinga lokuncibilika likhuphuka ngezinga lokushisa, ngokuvamile elingancibiliki ezintweni eziningi eziphilayo. izincibilikisi. Inokuqina okuhle kwe-PH kanye noshintsho oluncane lwe-viscosity ebangeni le-ph2-12. I-HEC inokumelana nosawoti ophezulu kanye nekhono le-hygroscopic, futhi inokugcinwa kwamanzi okuqinile kwe-hydrophilic. Isixazululo saso esinamanzi sinomsebenzi ongaphezulu futhi imikhiqizo ye-viscosity ephezulu ine-pseudoplasticity ephezulu. Ingenziwa ibe ifilimu esobala e-anhydrous enamandla amaphakathi, engangcoliswa kalula uwoyela, engathinteki ekukhanyeni, isenayo ifilimu ye-HEC encibilika emanzini. Ngemuva kokwelashwa okungaphezulu, i-HEC iyahlakazeka futhi ayihlangani emanzini, kodwa incibilika kancane. I-PH ingalungiswa ibe ngu-8-10 futhi incibilike ngokushesha.
Izakhiwo eziyinhloko
Hi-hydroxyethyl cellulose(HEC)ukuthi ingancibilika emanzini abandayo nasemanzini ashisayo, futhi ayinazo izici zejeli. Inohlu olubanzi lokushintshwa, ukunyibilika kanye ne-viscosity. Inokuqina okuhle kokushisa (ngaphansi kuka-140 ° C) futhi ayikhiqizi ngaphansi kwezimo ezine-asidi. imvula. Isixazululo se-hydroxyethyl cellulose(HEC) singakha ifilimu esobala, enezici ezingezona i-ionic ezingahlangani nama-ion futhi ezinokuhambisana okuhle.
Njenge-colloid evikelayo, i-Paint grade HEC ingasetshenziselwa i-vinyl acetate emulsion polymerization ukuze kuthuthukiswe ukuzinza kwesistimu ye-polymerization ebangeni elibanzi le-PH. Ekwenziweni kwemikhiqizo eqediwe ukwenza i-pigment, i-filler nezinye izithasiselo zihlakazeke ngokulinganayo, zizinzile futhi zinikeze umphumela wokuqina. Ingase futhi isetshenziselwe i-styrene, i-acrylic, i-acrylic namanye ama-polymers amisiwe njengama-dispersants, asetshenziswe kupende we-latex angathuthukisa kakhulu ukuqina, athuthukise ukusebenza kokulinganisa.

Indlela yesicelo ye-hydroxyethyl cellulose HEC emanziniupende
1. Engeza ngokuqondile lapho ugaya i-pigment: le ndlela ilula kakhulu, futhi isikhathi esisetshenzisiwe sifushane. Izinyathelo ezinemininingwane zimi kanje:
(1) Faka amanzi ahlanzekile afanelekile kwi-VAT ye-agitator ephezulu yokusika (ngokuvamile, i-ethylene glycol, i-ejenti yokumanzisa kanye ne-ejenti eyenza ifilimu iyengezwa ngalesi sikhathi)
(2) Qala ukunyakazisa ngesivinini esiphansi bese wengeza kancane i-hydroxyethyl cellulose
(3) Qhubeka ugoqa kuze kube yilapho zonke izinhlayiya sezicwile
(4) engeza i-mildew inhibitor, isilawuli se-PH, njll
(5) Govuza kuze kube yilapho yonke i-hydroxyethyl cellulose ichitheka ngokuphelele (i-viscosity yesisombululo yanda kakhulu) ngaphambi kokwengeza ezinye izingxenye kufomula, futhi ugaye kuze kube upende.
2. ifakwe umama wokulinda uketshezi: le ndlela ifakwe kuqala uketshezi oluningi lukamama, bese wengeza upende we-latex, inzuzo yale ndlela iguquguqukayo kakhulu, ingafakwa ngokuqondile ekupendeni imikhiqizo eqediwe, kodwa kufanele ibe isitoreji esifanele. . Izinyathelo nezindlela zifana nezinyathelo (1) - (4) ku-Method 1, ngaphandle kokuthi i-agitator yokusika ephezulu ayidingeki futhi i-agitator ethile kuphela enamandla anele ukugcina imicu ye-hydroxyethyl ihlakazeke ngokulinganayo kwisisombululo kwanele. Qhubeka ugqugquzela kuze kube yilapho incibilika ngokuphelele ibe isixazululo esiwugqinsi. Qaphela ukuthi i-mildew inhibitor kufanele yengezwe etshwaleni likamama ngokushesha okukhulu.
3. Uphuthu olufana nephenology: Njengoba izincibilikisi zemvelo ziyizincibilikisi ezimbi ze-hydroxyethyl cellulose, lezi zinyibilikisi zemvelo zingahlonyiswa ngephalishi. Izinyibilikisi ezisetshenziswa kakhulu eziphilayo ezifana ne-ethylene glycol, i-propylene glycol, nama-ejenti akha ifilimu (njenge-hexadecanol noma i-diethylene glycol butyl acetate), amanzi e-ice nawo awancibiliki kahle, ngakho-ke amanzi e-ice avame ukusetshenziswa noketshezi oluphilayo ephalishini. I-Gruel - njenge-hydroxyethyl cellulose ingafakwa ngokuqondile kupende. I-Hydroxyethyl cellulose igcwaliswe ngendlela yephalishi. Ngemuva kokungeza i-lacquer, chitha ngokushesha futhi ube nomphumela wokuqina. Ngemuva kokungeza, qhubeka ugoqa kuze kube yilapho i-hydroxyethyl cellulose ichitheka ngokuphelele futhi iyunifomu. Iphalishi elivamile lenziwa ngokuxuba izingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa nengxenye eyodwa ye-hydroxyethyl cellulose. Ngemva kwemizuzu engu-5-30, i-Paint gradeI-HECi-hydrolyzes futhi ikhuphuke ngokubonakalayo. Ehlobo, umswakama wamanzi uphezulu kakhulu ukuthi ungasetshenziselwa uphuthu.
4 .Izindaba ezidinga ukunakwa lapho uhlomisa ugologo kamama we-hydroxyethyl cellulose:
Pizixwayiso
1 Ngaphambi nangemuva kokwengeza ibanga likapendeI-HEC, kufanele inyakaziswe ngokuqhubekayo kuze kube yilapho isixazululo sisobala ngokuphelele futhi sicacile.
2. Hlanga kancane kancane i-hydroxyethyl cellulose ethangini lokuxuba. Ungawungezi ethangini lokuxuba ngobuningi noma ngokuqondile ebangeni lePaint eyindilingaI-HEC.
3 izinga lokushisa lamanzi kanye nenani le-pH lamanzi kuhlobene ngokusobala nokuqedwa kwebanga le-PaintI-HECi-hydroxyethyl cellulose, ngakho-ke kufanele kuqashelwe ngokukhethekile.
Ungangezi okuthile okuyisisekelo kungxube ngaphambi kwebanga le-PaintI-HECi-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa i-pH ngemva kokucwiliswa kusiza ukuncibilika.
5 .Ngokusemandleni, ukufakwa kusenesikhathi kwe-mildew inhibitor.
6 Uma usebenzisa i-viscosity ephezulu Ibanga likapendeI-HEC, ukuhlushwa kotshwala kamama akufanele kube ngaphezu kuka-2.5-3% (ngesisindo), ngaphandle kwalokho utshwala bomama kunzima ukusebenza.
Izinto ezithinta i-viscosity kapende we-latex
1.Uma amabhamuza omoya ayinsalela kupende, i-viscosity iyanda.
2.Ingabe inani le-activator namanzi kufomula kapende liyahambisana?
3 ekuhlanganisweni kwe-latex, okuqukethwe kwe-catalyst oxide eyinsalela yenani.
4. Umthamo wezinye izingqimba zemvelo kufomula kapende kanye nesilinganiso somthamo ngebanga lePaintI-HEC.)
5.enqubweni yokwenza upende, ukuhleleka kwezinyathelo zokwengeza i-thickener kufanelekile.
6.Ngenxa yokuyaluza ngokweqile kanye nomswakama owedlulele ngesikhathi sokuhlakazeka.
7.Ukuguguleka kwe-microbial of thickener.
