Ukusetyenziswa kwe-hydroxythyl seluplose kwipeyinti ye-Latex

I-tickener yepeyinti ye-Latex kufuneka ibe ne-Emolymer Polymer computer, kungenjalo ifilimu ehlekisayo iya kuba nexabiso elincinci lokuhlawula, kwaye iya kunciphisa i-viscofis engekho mthethweni kunye ne-coarsen yobukhulu becala. I-thi chuener iya kutshintsha isimangalo se-emulsion. Umzekelo, i-cusiyaric quickener iya kuba nefuthe elingenakuphikiswa kwi-ANUONIC ye-ANULSSIFIF yokuqhekeza i-emulsion. I-tickener efanelekileyo yepeyinti ye-Latex kufuneka ibe nezo profeti zilandelayo:

1. I-dosage ephantsi kunye ne-viscofity elungileyo

2. Uzinzo oluhle lokugcina, akukho kuncitshiswa kwe-viscosity ngenxa yesenzo se-enzymes, kwaye akukho kuncitshiswa kobushushu ngenxa yotshintsho kwixabiso lobushushu kunye nexabiso le-pH

3, Ukugcinwa kwamanzi kakuhle, akukho qhwa ngokucacileyo

I-4. Akukho ziphumo zibekwe ecaleni kweepropathi zefilimu ezinjengokunganyangeki kwesikratshi, i-glos, amandla okufihla kunye nokuxhathisa kwamanzi

I-5. Akukho scoccution ye-pigs

Itekhnoloji yokutyibilika yepeyinti ye-Latex yinqanaba elibalulekileyo lokuphucula umgangatho we-Latex kwaye unciphise iindleko. I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheethl seluplose yi-gickener efanelekileyo, eneziphumo zokwahlula-hlula ngokuzinza, ukuzinza kunye nokulungelelaniswa kwe-rohezulu kwipeyinti yepeyinti ye-upect.

Kwinkqubo yemveliso yepeyinti ye-Latex, i-HydroxyEtheetheetheetheethl seluplose (Hec) isetyenziswa njengokusasazeka, i-tickener kunye ne-piglomeration, yenza ifilimu yepeyinti, kwaye yenza ipeyinti ye-upex egudileyo ngakumbi. I-RUOOOLOCLO LOLUNTU, linokumela amandla amakhulu, kwaye inokubonelela ngenqanaba elifanelekileyo, ukuxhathisa okukrakra kunye nokufa kwe-pigment. Kwangelo xesha, i-hec inolwazi olugqwesileyo, kwaye ipeyinti ye-Latex ikhula nge-HEC ine-pseudeoplastity, ngokufanayo neendlela zokwakha ezinje ngebrashi, iqengqeleka, kwaye ingekho lula ukucoca kunye ne-SAG, kwaye incinci kwaye inciphile. UHec unophuhliso lwemibala ebalaseleyo. Ilugqwesileyo kakhulu ngobuqhetseba kunye neebhayini, zenza ukuba kube lula ukwenza iipeyinti zepeyinti zendlela kunye nokuzinza. Ukuqhelaniswa nokusetyenziswa kwenkqubo, yi-ion-ionther. Ke ngoko, inokusetyenziswa kububanzi be-pH (2 ~ 12), kwaye unokuxubene namacandelo eepeyinti zepeyinti ezifana ne-pigres esebenzayo, ezongeziweyo, i-stalts, i-stalts, i-stalts.

Akukho mpembelelo imbi kwifilimu ehlekisayo. Ngenxa yokuba isisombululo se-HCC sineempawu ezibonakalayo zamanzi ezibonakalayo, akukho lula ukugwetywa ngexesha lokuvelisa nokwakha, kunye notyekelo lwemingxunya yentaba-mlilo kunye nepinales zincinci.

Uzinzo oluhle lokugcina. Kwinkqubo yokugcina ixesha elide, ukusasazeka kunye nokumiswa kwe-pigment kungagcinwa, kwaye akukho ngxaki yombala odadayo kunye nokuqhuma. Xa kukho ungqimba lwamanzi amancinci kumphezulu wepeyinti kunye neqondo lobushushu logcino lutshintsha kakhulu. I-viscosity yayo isekhona.

I-Hec inokunyusa ixabiso le-PVC (uxinzelelo lwevolumu) ubume obuqinileyo ukuya kuthi ga kwi-50-60%. Ukongeza, i-topcoat tickener yepeyinti esekwe emanzini inokusebenzisa i-HEC.

Okwangoku, iziqwengana ezisetyenziswa kwiipeyinti eziphezulu zasekhaya ezingeniswayo ze-hec kunye ne-acrylic thelymers (kubandakanya iipolyacylates, i-hulfolly okanye i-hulforder okanye i-eullymer okanye i-eullym okanye i-celsoly emulsion shubleaid kunye ne-metacrylic acid) i-acid.

I-HydroxyEtheetheetheethy inokusetyenziselwa

I-1. Njengomntu osasazeke okanye oyikhuselayo

Ngokubanzi, i-hec ngohlobo lwe-viscosity ye-10 ukuya kwi-30 mpas isetyenzisiwe. I-hec ye-HC ukuya kuthi ga kwi-300mpa s isetyenziselwa ukudityaniswa kunye ne-anaonic okanye i-cioric surfacints, kunye nefuthe lokusasaza lingcono. Ixabiso lesalathiso liyi-0.05% yobunzima be-monomer.

I-2, njenge-thi checker

Sebenzisa i-15000MPA. I-suremere sussage ye-hec ephezulu ye-hec ngaphezulu s yi-0.5 ukuya kwi-1% yobunzima be-Latex, kwaye ixabiso le-PVC linokufikelela malunga ne-60%. Kwipende ye-FECATEX, i-hec ye-20PA, isetyenziswa, kunye neepropathi ezahlukeneyo zepeyinti ye-tempx zezona zibalaseleyo. Ixabiso lokusebenzisa nje i-hec apha ngasentla 30O00pa.S iphantsi. Nangona kunjalo, inqanaba kunye nezinye iimpawu zepeyinti ye-Latex ayilunganga. Ukusuka kwimbono yemfuno esemgangathweni kunye nokunciphisa iindleko, kungcono ukusebenzisa i-hec ephakathi nephezulu.

I-3. Ubume bendlela yokupeyinta ipeyinti

I-hec ephathwe i-HEC inokongezwa kwi-powder eyomileyo okanye ifom yesilayidi. Umgubo owongezwe ngokuthe ngqo kwi-pigment yokugaya. I-PH yendawo yokongeza kufuneka ibe yi-7 okanye isezantsi. Izinto ze-alkaline ezinje ngokusasazeka zinokongezwa emva kokuba i-HE imanzi kwaye ichithwe ngokupheleleyo. Isilayidi esenziwe nge-HEC kufuneka idityaniswe kwi-slicry ngaphambi kokuba i-HEC ibe nexesha elaneleyo lokutyibilika kwaye ityhutywe kwimeko engaqhelekanga. I-hec sutarries inokulungiswa nge-glycol ye-glycoc yokulungisa.

I-4. I-Anti-Maildew yepeyinti ye-Latex

I-HOCOLM-ALD-ALD-ALDALMBODS ECBODODODODS xa ityhilwe kubumba obucacisiweyo kwi-selupes kunye nezahlulo zayo. Ukongeza iipeyinti zokupeyinta zodwa akwanelanga, onke amacandelo kufuneka e-Enzyme simahla. Izithuthi zemveliso zepeyinti ye-Latex kufuneka zigcinwe zicocekile kwaye zicocekile, kwaye zonke izixhobo kufuneka zichithwe rhoqo nge-0.5% yesisombululo seSercury.
