Gelation-ka waxaa loola jeedaa dhumucdi ama jeexista resin UV ama dahaarka heerkulka iyo wakhtiga la cayimay.
Sababaha ugu muhiimsan ee gelatinization of resin UV ama daahan waa sida soo socota:
1. Wixii ka dambeeya nolosha shelf, nolosha shelf ee raajada UV ee xaaladaha kaydinta wanaagsan waa in aanay dhaafin lix bilood.Laakiin Z wanaagsan waxaa lagu isticmaali karaa saddex bilood gudahood.
2. Xabagta UV waa in lagu kaydiyaa foosto balaastig ah ama fuustooyin bir ah oo lagu dahaadhay caag.Aions-yada birtu waxay yaraynaysaa tamarta firfircoonida ee labajibbaaran bonds ee xabagta UV waxayna bilaabi doontaa polymerization, taasoo keenta gelation resin.Sidaa darteed, haddii lakabka dhejiska ee balaastigga ah ee foosto caagga ah uu dhaawacmo, lakabka birta ah ee qaawan wuxuu keeni doonaa jeelka resin.
3. Heerkulka kaydinta aadka u hooseeya (ka hooseeya 0 ℃) ayaa soo dajin doona polymerization inhibitor ee filimka rinjiga, taasoo keentay in resin self polymerization iyo resin gelation.
4. Xabagta UV waa in si adag looga ilaaliyo qorraxda tooska ah inta lagu jiro kaydinta.Haddii kale, way fududahay in la keeno gelation resin.
5. Haddii foostada ay aad u buuxsanto, ma jirto ogsijiin ku filan oo ka hortagaysa polymerization, taas oo keeni doonta gelitaanka resin.
Ka-hortagga gelation:
1. Viscosity of resin iyada oo aan la milmin monomer waa mid aad u sarreeya.Isticmaalayaasha qaarkood waxay si qalad ah u malayn doonaan in resin-ka la sameeyay gelatinized.Dhab ahaantii, way fududahay in la ogaado in resinku yahay gelatinized ka dib kuleylka.Xabagta aan lahayn jelatinization waxay yeelan doontaa dareere wanaagsan ka dib kuleylka.
2. Marka loo eego isticmaalka resin UV, hababka ogaanshaha iyo tilmaamayaasha filimka dahaarka UV waxay la mid yihiin kuwa kale ee dahaarka, kuwaas oo ku kala duwan codsiga gaarka ah.Waxaa jiri doona dhibaatooyin kala duwan oo ku saabsan codsiga daaha UV.Gelatinization oo kaliya inta lagu jiro kaydinta ayaa si dhow ula xidhiidha xabagta UV lafteeda, iyo dhibaatooyinka kale waxaa lagu xallin karaa iyadoo la hagaajinayo caanaha daahan UV.Maaddaama uvpaint uu ka kooban yahay qaybo kala duwan, waxa kale oo ay saamaysaa fogaanta iftiinka iftiinka iftiinka iyo wakhtiga iftiinka, iyo waxqabadkeeda filimku waa natiijada ficilka dhamaystiran ee arrimo kala duwan.Isla qaacidadii, isla markiiba ku beddel resin isku mid ah.Sababtoo ah kala duwanaanshaha resins ee soo saarayaasha kala duwan, waxqabadka filimku waa la bedeli doonaa, caanaha ayaa u baahan in la hagaajiyo.Si kastaba ha noqotee, ilaa iyo inta resinka aan la jebin ama gelatinized rinjiga diyaarsan, waxqabadka filimka waxaa lagu hagaajin karaa caanaha.
3. Waxaa jira sababo badan oo ah jelatinization ee rinjiga UV, kuwaas oo aan la xiriirin oo kaliya resin.Marka hore, waa in aan eegno in ay sababtay kaydinta aan habboonayn.Sababo la xiriira ku darista photosensitizer ee daahan UV, xaaladdeeda kaydinta ayaa ka adag kuwa UV resin.Waa lagama maarmaan in lagu kaydiyo mugdiga si looga fogaado in la arko iftiinka.Marka labaad, sawir-qaadista la doortay waa mid tayadeedu liidato, xitaa haddii lagu kaydiyo mugdiga, waxay si tartiib tartiib ah u jajabin doontaa oo waxay keenaysaa gelation of daahan la daweeyay.
4. Tayada monomer sidoo kale waa arrin muhiim ah oo saameeya xasilloonida kaydinta.
