Ukuqulunqwa kwefilimu yeibhodi eqatywe ngombalaukutyabeka ikakhulu kubandakanya imiba emibini: ukuncamathelisa ukutyabeka kunye nokomisa ukomisa.
Ukuncamatheliswa kwebhodi eqatywe ngombala
Isinyathelo sokuqala sokubambelela phakathi kwe-substrate strip yentsimbi kunye nokwaleka kukumanzisa kwebhodi egqunywe ngombala kwi-substrate surface. Ukumanzisa okugqumayo kunokutshintsha umoya kunye namanzi afakwe kuqala kumphezulu wentsimbi. Ngexesha elifanayo, ukuchithwa kwe-solvent kwi-substrate surface kukhokelela ekuchithekeni okanye ekudumbeni. Ukuba iiparamitha zokunyibilika kwe-resin eyenza ifilimu yombala webhodi egqunywe ngombala kunye nomphezulu we-substrate ukhethwe ngokufanelekileyo, iya kwenza umaleko ongaguqukiyo phakathi komphezulu webhodi egqunywe ngombala kunye nefilimu yokugquma, oku kubalulekile ekunamatheleni okuhle Ukwaleka.
Ukomiswa kweBibhodi eqatywe ngombalaukutyabeka
Ulwakhiwo oluncamathelayo lwebhodi eqatywe ngombala lugqibezela kuphela inyathelo lokuqala lokwakheka kwefilimu yokwaleka kwinkqubo yokwaleka yebhodi eqatywe ngombala, kwaye inkqubo yokuba yifilim eqinileyo eqhubekayo kufuneka iqhubeke, enokugqiba yonke inkqubo yokwakheka kwefilimu yokwaleka. . Inkqubo yokutshintsha ukusuka "kwifilimu emanzi" ukuya "kwifilimu eyomileyo" idla ngokubizwa ngokuba "yomisa" okanye "ukunyanga". Le nkqubo yokomisa kunye nokunyanga iyona nto ingundoqo yenkqubo yokwenza ifilimu yokugqoka. Iingubo ezineefom ezahlukeneyo kunye neengqungquthela zineendlela zabo zokwenza ifilimu, ezichongwa yimpahla yezinto zokwenza ifilimu ezisetyenziselwa ukugqoka. Ngokwesiqhelo, sahlulahlule inkqubo yokwenza ifilimu yokwaleka ngokweendidi ezimbini:
(1) Ayinanguquko. Ngokubanzi, ibhekisa kwindlela yokwenza ifilimu ebonakalayo, eyona nto ixhomekeke ekuguqukeni kwezinyibilikisi okanye ezinye izinto ezisasazwayo kwifilimu yokugquma, ngokuthe ngcembe ikhulisa i-viscosity yefilimu yokugquma kunye nokwenza ifilimu eqinileyo yokugquma. Ngokomzekelo, iingubo ze-acrylic, iingubo zerubha ezikloriniweyo, iingubo ze-ethylene, njl.
(2) Utshintsho. Ngokubanzi, ibhekisa kukwenzeka kweekhemikhali ngexesha lenkqubo yokwenza ifilim, kwaye ukugquma kuxhomekeke ikakhulu kutshintsho lwekhemikhali ukwenza ifilimu. Le nkqubo yokwenza ifilimu ibhekisela kwi-polymerization yezinto ezenza ifilimu kwiingubo, ezibizwa ngokuba yi-polymers, emva kokusetyenziswa. Kunokuthiwa yindlela ekhethekileyo ye-polymer synthesis, elandela ngokupheleleyo indlela yokusabela ye-polymer synthesis. Ngokomzekelo, iingubo ze-alkyd, iingubo ze-epoxy, iingubo ze-polyurethane, iingubo ze-phenolic, njl. Nangona kunjalo, iingubo ezininzi zanamhlanje azenzi iifilimu ngendlela enye, kodwa zithembele kwiindlela ezininzi ekugqibeleni zenze iifilimu, kwaye i-coil coil luhlobo oluqhelekileyo lwefilimu. exhomekeke kwiindlela ezininzi ukuze ekugqibeleni wenze iifilimu.
