ipropati yeekhemikhali

Ngokwesakhiwo seekhemikhali ezahlukeneyo, olu hlobo lwearhente yokulinganisa luneentlobo ezintathu eziphambili: i-acrylic acid, i-organic silicon kunye ne-fluorocarbon. Iarhente yokulinganisa yiarhente yokongeza esetyenziswa rhoqo, enokwenza udonga lube yifilimu egudileyo, egudileyo nefanayo kwinkqubo yokomisa. Inganciphisa ngempumelelo uxinzelelo lomphezulu wolwelo lokugcoba, iphucule ukulingana kwayo kunye nokufana kodidi lwezinto. Ingaphucula ukuvuleka kwesisombululo sokugqiba, inciphise amathuba okuba namabala kunye neempawu xa ixukuxa, yonyuse ukugquma, kwaye yenze ifilimu ifane kwaye ibe yendalo. Ngokuyintloko ii-surfactants, ii-organic solvents njalo njalo. Kukho iintlobo ezininzi zeearhente zokulinganisa, kwaye iintlobo zeearhente zokulinganisa ezisetyenziswa kwiingubo ezahlukeneyo azifani. Iisolvents eziphezulu zokubilisa okanye i-butyl cellulose zingasetyenziswa kwiingubo ezisekwe kwi-solvent. Kwi-arhente yokugqiba esekwe emanzini ene-surfactants okanye i-polyacrylic acid, i-carboxymethyl cellulose

Intshayelelo yemveliso kunye neempawu zayo

Iiarhente zokulinganisa zahlulwe ngokubanzi zibe ziindidi ezimbini. Enye kukulungisa i-viscosity yefilimu kunye nexesha lokulinganisa ukusebenza, olu hlobo lwearhente yokulinganisa ubukhulu becala zii-solvents okanye imixube ye-organic ephezulu yokubila, njenge-isoporone, i-diacetone alcohol, i-Solvesso150; Enye kukulungisa iipropati zomphezulu wefilimu ukuze zisebenze, abantu ngokubanzi bathi iarhente yokulinganisa ikakhulu ibhekisa kolu hlobo lwearhente yokulinganisa. Olu HLOBO LWE-AGENT YOKULINGANISA lufudukela kumphezulu wefilimu ngokuhambelana okulinganiselweyo, luchaphazela iipropati zomphezulu wefilimu ezifana noxinzelelo lwe-INTERfacial, kwaye lwenza ifilimu ifumane i-leveling elungileyo.

sebenzisa

Umsebenzi ophambili wokugquma kukuhombisa nokukhusela, ukuba kukho iziphene zokuhamba kunye nokulinganisa, akuchaphazeli nje kuphela inkangeleko, kodwa konakalisa nomsebenzi wokukhusela. Njengokuba ukwakheka kokuncipha okubangelwa bubukhulu befilimu akwanelanga, ukwakheka kwemingxuma yephini kuya kukhokelela ekungaqhubeki kwefilimu, oku kuya kunciphisa ukhuseleko lwefilimu. Kwinkqubo yokwakha ukugquma kunye nokwakheka kwefilimu, kuya kubakho utshintsho oluthile lomzimba kunye nolwekhemikhali, olu tshintsho kunye nohlobo lokugquma ngokwalo, kuya kuchaphazela kakhulu ukuhamba kunye nokulinganisa kokugquma.
Emva kokuba i-coating isetyenzisiwe, kuza kuvela ii-interfaces ezintsha, ngokubanzi i-interface yolwelo/eqinileyo phakathi kwe-coating kunye ne-substrate kunye ne-interface yolwelo/yegesi phakathi kwe-coating kunye nomoya. Ukuba i-INTERfacial tension YE-interface yolwelo/eqinileyo phakathi kwe-coating kunye ne-substrate iphezulu kune-critical surface tension ye-substrate, i-coating ayiyi kukwazi ukusasazeka kwi-substrate, nto leyo eya kuvelisa iziphene zokulinganisa ezifana ne-fisheye kunye ne-shrinkage holes.
UKUPHUMA KWESISOMBULULO NGEXESHA LENKQUBO YOKUMISA ifilimu kuya kukhokelela kumahluko obushushu, uxinano kunye noxinzelelo lomphezulu phakathi komphezulu kunye nangaphakathi kwefilimu. Olu mahluko lukhokelela kwintshukumo eguquguqukayo ngaphakathi kwefilimu, okwenza oko kubizwa ngokuba yi-vortex yeBenard. I-vortex yeBenard ikhokelela kwixolo le-orenji; Kwiinkqubo ezine-pigment engaphezulu kwesinye, ukuba kukho umahluko othile ekushukumeni kwamasuntswana e-pigment, i-vortex yeBenard ikwakhokelela kumbala odadayo kunye neenwele, kwaye ulwakhiwo oluthe nkqo luya kukhokelela kwimigca yesilika.
INKQUBO YOKUMISA YEFILIMU YEPEYINTI NGAMAXESHA AMANYE IVELISA AMAQELA ECOLLOIDAL ANGANCIPHI, Ukuveliswa kwamaqhekeza eCOLLOIDAL angaNCIPHI kuya kukhokelela ekwakhiweni kwe-surface tension gradient, okuhlala kukhokelela ekwenziweni kwemingxunya yokuncipha kwifilimu yepeyinti. UMZEKELO, KWINKQUBO YOKUQINISA OKUNXIBELELENE NEMIBANDELA, APHAKATHI OKUQULUNQWEYO KUNENTLAMBO IQULETHE I-RESIN ENGAPHEZU KWENYE, I-resin enganyibilikiyo kakhulu inokwenza amaqhekeza e-colloidal anganyibilikiyo njengoko i-solvent itshintsha ngexesha lenkqubo yokomisa ifilimu yepeyinti. Ukongeza, kwifomyula equlethe i-surfactant, ukuba i-surfactant ayihambelani nenkqubo, okanye kwinkqubo yokomisa kunye ne-volatilization ye-solvent, utshintsho lwalo loxinzelelo lukhokelela kutshintsho ekunyibilikeni, ukwakheka kwamaconsi angahambelaniyo, kuya kwenza noxinzelelo lomphezulu. Oku kunokukhokelela ekwakhiweni kwemingxunya yokuncipha.
Kwinkqubo yokwakhiwa kwepeyinti kunye nokwenziwa kwefilimu, ukuba kukho ungcoliseko lwangaphandle, lunokukhokelela ekuncipheni kwemingxunya, i-fisheye kunye nezinye iziphene zokulinganisa. Ezi zingcoliseko zihlala zivela emoyeni, kwizixhobo zokwakha nakwi-substrate oil, uthuli, kwi-peyinti inkungu, kumphunga wamanzi, njl.njl.
Iimpawu zepeyinti ngokwayo, ezinje nge-viscosity yokwakha, ixesha lokomisa, njl.njl., nazo ziya kuba nefuthe elikhulu ekulinganisweni kokugqibela kwefilimu yepeyinti. I-viscosity yokwakha ephezulu kakhulu kunye nexesha elifutshane kakhulu lokomisa zihlala zivelisa umphezulu ongalinganiyo kakuhle.
Kungoko ke, kuyimfuneko ukongeza i-arhente yokulinganisa, ngokusebenzisa upende kwinkqubo yokwakha kunye nokwakheka kwefilimu yotshintsho oluthile kunye neempawu zokudibanisa ukuze zilungiswe, ukunceda upende ufumane ulungelelwaniso olufanelekileyo.
