Ụlọ ọrụ obibi akwụkwọ na-ezo aka na ya dị ka ihe nkiri ink crystallization, vitrification, ma ọ bụ mirroring.
Iji meziwanye nchapụta nke onyonyo na akụkụ ederede, ọtụtụ ndị na-emepụta agbakwunyela mmanụ silicone na sistemụ ink n'afọ ndị na-adịbeghị anya. Otú ọ dị, oke mmanụ silicone na-ebutekarị mbelata nke ihe nkiri ink kwụ ọtọ.
Enwere echiche dị iche iche ugbu a maka ihe kpatara kristal nke ihe nkiri ink. Dị ka ozizi crystallization si kwuo, crystallization bụ usoro nke ịmepụta kristal site na mmiri mmiri (mmiri ma ọ bụ gbazee) ma ọ bụ ala gas. Ihe nke solubility ya na-ebelata nke ukwuu site na ibelata okpomọkụ, na ngwọta ya nwere ike iru saturation na crystallize site na jụrụ oyi; Ihe nke solubility ya na-ebelata ntakịrị site na mbelata okpomọkụ, na-egbuke egbuke mgbe ụfọdụ ihe mgbaze na-ekupụ wee daa jụụ. Ụfọdụ ndị kwenyere na crystallization nke nkwakọ obibi akwụkwọ oyiyi na ederede (ink film oyi akwa) ka a na-akpọ recrystallization... A na-emepụta usoro ihe nkiri ink nke a na-ebipụta site na ihe mgbaze ọkụ (evaporation) na mgbe ahụ jụrụ oyi, nke a makwaara dị ka recrystallization.
2, Ụfọdụ ndị mmadụ kweere na crystallization (crystallization) nke nkwakọ obibi akwụkwọ ink bụ tumadi mere site crystallization nke pigments na ink usoro.
Anyị maara na mgbe kristal pigmenti bụ anisotropic, ọnọdụ kristal ha bụ agịga ma ọ bụ mkpanaka. Mgbe ị na-akpụ ihe nkiri ink, a na-ahazi ntụziaka ogologo n'ụzọ dị mfe n'akụkụ ụzọ mgbaba nke resin (ihe njikọ) na usoro, na-ebute mbelata dị ukwuu; Otú ọ dị, ọ dịghị ndokwa ntụziaka n'oge spherical crystallization, na-akpata obere shrinkage. Ihe ndị na-adịghị ahụkebe na sistemu ink obibi akwụkwọ na-enwekarị kristal dị okirikiri, dị ka ink mbipụta akwụkwọ cadmium, nke nwekwara obere shrinkage (crystallization).
The urughuru size na-emetụta ndị ịkpụzi shrinkage ọnụego na ịkpụzi shrinkage ruru. Mgbe ahụ pigmenti ahụ buru ibu ma ọ bụ obere ruo n'ókè ụfọdụ, ọnụ ọgụgụ na-akpụzi shrinkage na shrinkage ruru bụ nke kacha nta. N'aka nke ọzọ, resins nwere kristal buru ibu na ọdịdị dị iche iche na-egosipụta obere ịkpụzi mbelata, ebe resins nwere nnukwu kristal na ọdịdị na-abụghị nke okirikiri na-egosipụta nnukwu ịkpụzi shrinkage.
Na nkenke, ma ọ bụ subtractive Ịgwakọta nke agba pigments ma ọ bụ mmakọ Ịgwakọta nke agba ìhè, ziri ezi ojiji nke pigmenti na-abụghị nanị metụtara ha chemical Ọdịdị, ma na-n'ụzọ dị ukwuu dabere na ha anụ ahụ Njirimara, dị ka crystal urughuru size nkesa. phenomena condensation, ngwọta siri ike, na ihe ndị ọzọ na-emetụta; Anyị kwesịkwara ime ka a ziri ezi nwale nke uru na ọghọm nke ma inorganic na organic pigmenti, nke mere na ha na-ebikọ ọnụ, na nke ikpeazụ esetịpụ isi ọnọdụ.
Mgbe ị na-ahọrọ nkwakọ obibi akwụkwọ ink (pigmenti), ọ dịkwa mkpa ịtụle ike agba ya (nke kacha mma na mgbasawanye, nke dị elu nke ike agba, mana enwere oke uru karịa nke ike agba ga-ebelata) ike mkpuchi (njiri mara mma). nke pigmenti n'onwe ya, ihe dị iche na ntugharị refractive n'etiti pigmenti na ihe nkedo resin chọrọ maka agba agba, nha nke pigmenti ahụ, ọdịdị kristal nke pigmenti, na ihe nhazi nke molecular nke pigmenti dị elu karịa nke ndị symmetrical. obere kristal).
