I-HEC yebanga lokupeyinta
Ibanga lokupeyintaI-HEC Hydroxyethyl cellulose luhlobo lwe-polymer enyibilikayo emanzini engeyiyo ionic, i-powder emhlophe okanye emthubi, kulula ukuyikhupha, ayinavumba kwaye ayinancasa, inokunyibilika emanzini abandayo nashushu, kwaye izinga lokunyibilika liyakhula ngobushushu, ngokubanzi ayinyibiliki kwiinyibilikisi ezininzi zezinto eziphilayo. Izinzile kakuhle kwi-PH kwaye itshintsha kancinci kwi-viscosity kuluhlu lwe-ph2-12. I-HEC inokumelana netyuwa ephezulu kunye nobuchule be-hygroscopic, kwaye inokugcinwa kwamanzi okunamandla okubamba amanzi. Isisombululo sayo samanzi sinomsebenzi womphezulu kwaye iimveliso ze-viscosity ephezulu zine-pseudoplasticity ephezulu. Ingenziwa ibe yifilimu ecacileyo engenamanzi enamandla aphakathi, engangcoliswa lula yioyile, engachaphazeleki kukukhanya, isenayo ifilimu enyibilikayo emanzini ye-HEC. Emva konyango lomphezulu, i-HEC iyasasazeka kwaye ayidibani emanzini, kodwa iyanyibilika kancinci. I-PH inokulungiswa ibe yi-8-10 kwaye inyibilike ngokukhawuleza.
Iipropati eziphambili
Hi-ydroxyethyl cellulose(HEC)Ukuba inokunyibilika emanzini abandayo nasemanzini ashushu, kwaye ayinazo iimpawu zejeli. Inoluhlu olubanzi lokutshintshwa, ukunyibilika kunye ne-viscosity. Izinzile kakuhle kubushushu (ngaphantsi kwe-140°C) kwaye ayivelisi imvula phantsi kweemeko ze-asidi. Isisombululo se-hydroxyethyl cellulose (HEC) sinokwenza ifilimu ecacileyo, eneempawu ezingezizo ze-ionic ezingadibaniyo nee-ion kwaye zinokuhambelana kakuhle.
Njenge-colloid ekhuselayo, i-Paint grade HEC ingasetyenziselwa i-vinyl acetate emulsion polymerization ukuphucula uzinzo lwenkqubo ye-polymerization kuluhlu olubanzi lwe-PH. Ekwenzeni iimveliso ezigqityiweyo ukwenza i-pigment, i-filler kunye nezinye izongezo zisasazeke ngokulinganayo, zizinzile kwaye zibonelele ngesiphumo sokutyeba. Ingasetyenziselwa i-styrene, i-acrylic, i-acrylic kunye nezinye ii-polymers ezixhonyiweyo njengezisasazi, ezisetyenziswa kwipeyinti ye-latex zinokuphucula kakhulu ukutyeba, ziphucule ukusebenza kwe-leveling.

Indlela yokusebenzisa i-hydroxyethyl cellulose HEC emanzini ahamba ngamanziipeyinti
1. Yongeza ngqo xa usika i-pigment: le ndlela yeyona ilula, kwaye ixesha elisetyenziswayo lifutshane. Amanyathelo aneenkcukacha ngala alandelayo:
(1) Yongeza amanzi acocekileyo afanelekileyo kwi-VAT ye-agitator yokusika ephezulu (ngokubanzi, i-ethylene glycol, i-wetting agent kunye ne-film forming agent zongezwa ngeli xesha)
(2) Qala ukuxuba ngesantya esiphantsi uze wongeze kancinci i-hydroxyethyl cellulose
(3) Qhubeka uvuselela ude wonke amasuntswana afunxwe
(4) yongeza i-mildew inhibitor, i-PH regulator, njl.njl.
(5) Xuba de yonke i-hydroxyethyl cellulose ichitheke ngokupheleleyo (i-viscosity yesisombululo inyuswe kakhulu) ngaphambi kokongeza ezinye izinto kwifomyula, uze uyigaye ide ibe yipeyinti.
2. ixhotyiswe ngolwelo lukamama olulindileyo: le ndlela ixhotyiswe kuqala ngoxinaniso oluphezulu lolwelo lukamama, uze wongeze ipeyinti yelatex, inzuzo yale ndlela kukuguquguquka okukhulu, ingongezwa ngokuthe ngqo kwiimveliso ezigqityiweyo zepeyinti, kodwa kufuneka igcinwe ngendlela efanelekileyo. Amanyathelo kunye neendlela ziyafana namanyathelo (1) – (4) kwiNdlela yoku-1, ngaphandle kokuba i-agitator yokusika ephezulu ayifuneki kwaye kuphela i-agitator enamandla aneleyo okugcina iifayibha ze-hydroxyethyl zisasazeke ngokulinganayo kwisisombululo eyaneleyo. Qhubeka uvuselela ide inyibilike ngokupheleleyo ibe sisisombululo esityebileyo. Qaphela ukuba i-mildew inhibitor kufuneka yongezwe kwi-mother liquor ngokukhawuleza.
3. I-phenology efana ne-porridge: Ekubeni i-organic solvents zi-solvents ezimbi kwi-hydroxyethyl cellulose, ezi organic solvents zinokuxhotyiswa nge-porridge. I-organic solvents ezisetyenziswa kakhulu njenge-ethylene glycol, i-propylene glycol, kunye nee-film forming agents (ezifana ne-hexadecanol okanye i-diethylene glycol butyl acetate), amanzi omkhenkce nawo ayi-solvent imbi, ngoko ke amanzi omkhenkce adla ngokusetyenziswa kunye ne-organic liquids kwi-porridge. I-Gruel-like hydroxyethyl cellulose inokongezwa ngokuthe ngqo kwipeyinti. I-Hydroxyethyl cellulose igcwele kwimo ye-porridge. Emva kokongeza i-lacquer, yinyibilikise ngoko nangoko kwaye ibe nefuthe lokutyeba. Emva kokongeza, qhubeka uvuselela ude i-hydroxyethyl cellulose ichitheke ngokupheleleyo kwaye ifane. I-porridge eqhelekileyo yenziwa ngokuxuba iindawo ezintandathu ze-organic solvent okanye amanzi omkhenkce kunye nenxalenye enye ye-hydroxyethyl cellulose. Emva kwemizuzu emi-5-30, i-Paint gradeI-HECi-hydrolyzes kwaye inyuka ngokubonakalayo. Ehlotyeni, ukufuma kwamanzi kuphezulu kakhulu ukuba kungasetyenziswa kwi-porridge.
4. Izinto ezifuna ingqalelo xa kuxhotyiswa utywala bomama be-hydroxyethyl cellulose:
Pizilumkiso
1 Ngaphambi nasemva kokongeza umgangatho wepeyintiI-HEC, kufuneka ixutywe rhoqo de isisombululo sibe sobala ngokupheleleyo kwaye sicace.
2. Hluza i-hydroxyethyl cellulose kwi-mixing tank kancinci. Musa ukuyifaka kwi-mixing tank ngobuninzi okanye ngokuthe ngqo kwi-bulk okanye kwi-spherical Paint gradeI-HEC.
Ubushushu bamanzi obu-3 kunye nexabiso le-pH lamanzi zinolwalamano olucacileyo nokunyibilika komgangatho wepeyintiI-HECi-hydroxyethyl cellulose, ngoko ke kufuneka inikwe ingqalelo ekhethekileyo kuyo.
Musa ukongeza into esisiseko kumxube ngaphambi kodidi lwepeyintiI-HECUmgubo we-hydroxyethyl cellulose ufunxwa ngamanzi. Ukunyusa i-pH emva kokufunxwa kunceda ukunyibilika.
5. Kangangoko kunokwenzeka, kongezwa kwangoko isithinteli sokubola.
6 Xa usebenzisa ipeyinti enoburhabaxa obuphezuluI-HEC, uxinaniso lotywala obuvela kunina akufuneki lube ngaphezulu kwe-2.5-3% (ngokobunzima), kungenjalo utywala obuvela kunina kunzima ukulusebenzisa.
Izinto ezichaphazela i-viscosity yepeyinti ye-latex
1. Ukuba kukho amaqamza omoya aseleyo kwipeyinti, kokukhona i-viscosity iphezulu.
2. Ingaba ubungakanani be-activator kunye namanzi kwifomula yepeyinti buyahambelana?
3 ekuhlanganisweni kwe-latex, umxholo we-catalyst oxide oseleyo wobungakanani.
4. Umlinganiselo wezinye izinto zokutyebisa zendalo kwifomula yepeyinti kunye nomlinganiselo womlinganiselo ngebanga lepeyintiI-HEC.)
5. Kwinkqubo yokwenza ipeyinti, ulandelelwano lwamanyathelo okongeza isithambisi lufanelekile.
6.Ngenxa yokushukuma kakhulu kunye nokufuma okugqithisileyo ngexesha lokusasazeka.
7. Ukukhukuliseka kwe-microbial ye-thickener.
