Warqadani waxay diiradda saaraysaa labanlaabyada xabagta laminting ee aan dareeraha lahayn, iyadoo ka hadlaysa simida hantida alaabada aan dareeraha lahayn.
1. Macnaha aasaasiga ah ee Qiimaynta Hantida
Heerarka hantida waa awooda dahaarka si ay si siman oo siman ugu siman yihiin dusha sare ee substrates.
2. Xidhiidhka iyo Saamaynta Heerarka Marxalado kala duwan
Doodda soo socota, walxaha wax-soo-saarka ayaa isku mid ah, oo ay ku jiraan miisaanka dahaadhka, heerkulka, cadaadiska, iwm. Sababtoo ah dhammaan walxaha waxay keeni doonaan isbeddel ku yimaada laminates kama dambaysta ah, waxaan u arki doonaa doorsoomayaashan inay yihiin kuwo go'an.
Sababtoo ah koollada aan dareeraha lahayni ma laha wax dareere ah si ay u noqdaan saldhigga, hantida simidda waa waxqabadka koollada lafteeda.Marka la eego, waxay noqon doontaa mid saafi ah, laakiin koollada aan dareeraha lahayn ayaa weli leh astaamo u gaar ah.
Marka hore, simaynta hantida koollada SF waxay leedahay xidhiidh dhow oo la xidhiidha viscosity of koollada lafteeda.Halka viscosity uu xidhiidh toos ah la leeyahay heerkulka oo uu u kala duwan yahay si rogan, taas oo macnaheedu yahay koollada SF-ta ayaa yaraan doonta marka heerkulku kordho.Kadib heerkulka qolka hoostiisa, viscosities ee xabagta cayriin ee SF waxay leeyihiin farqi aad u weyn marka loo eego noocyada kala duwan ee xabagta SF iyo sifooyinka jirka.Si kastaba ha ahaatee, marka la eego heerkulka ku habboon ee hal model koollada SF, kala duwanaanshaha kala duwanaanshaheeda ma ahan mid muuqda.Sidaa darteed, wax soo saarka viscosity hoose waxaa laga yaabaa inuusan ahayn kan ka wanaagsan marka la barbar dhigo hal nooc oo viscosity sare leh oo SF ah oo leh mid mawduuc hooseeya.Tusaale ahaan, WD8262A/B ee KANGDA NEW MATTERIALS, oo hoos yimaada heerkulka ay ku shaqeyso (qiyaastii 45 ℃), viscositykeedu waa 1100 mpa.s.Laakin marka la daadinaayo PET.INK/ALU, waxay ku gaari kartaa muuqaal fiican oo aan dhibco lahayn inta lagu jiro lamination koowaad.Gunaanad ahaan, macnaheedu maaha in viscosity hoose uu keeni karo muuqaal wanaagsan.Isbeddelka firfircoon ee xabagta SF waa xilli degdeg ah, kaas oo u baahan dhowr walxood si loo gaaro saameyn wanaagsan.Dhanka kale, viscosity ayaa leh dabaqa ugu hooseeya.Tusaale ahaan, ka hooseeya 80-90 ℃ (Laba qaybood SF koollada), viscosity wuxuu leeyahay isbeddello yar oo heerkulka kor u kaca.
Heerarka barafka waa sii wadida jireed ee heerka dhejiska isku dhafan.Habka dahaadhka ka dib, hantideeda simaynta ayaa sii yaraanaysa iyadoo ay weheliso falcelinta degdega ah ee u dhaxaysa qaybaha A&B iyo hoos u dhaca heerkulka.Guud ahaan, heerka koobaad ee xabagta SF waxaa loo tixgaliyaa siminta dabaysha ka dib.Waqtigaan viscosity-ka koollada ayaa ka weynaan doona xabagta isku dhafan ee rollers-ka cabbirka.
Heerarka xabagta ceyriinka ah waxay la macno tahay isbarbardhigga hantida koollada ee durbaanka ka hor inta aan la isku darin.Hantida la simi karo kama qayb qaadanayso habka loo maro filimada ama foils.
Hantida heerka labaad waa in, ka dib habka laminating iyo marxaladda daawaynta, koollada SF waxay gashaa marxalad falcelin degdeg ah oo iskutallaab ah iyada oo ay sakhraansan tahay heerkulka, iyo waxqabadka heerkulku hoos u dhaco si dhammaystiran loo waayo.
3. Gabagabo
Heerarka hantida koollada ceeriin ee SF ka hor inta aan la isku qasin> hantida heerka labaad ahSidaa darteed, isbeddelka isbeddelka viscosity ee xabagta SF dhab ahaantii waa geeddi-socod kor u kacaya, kaas oo si cad uga duwan xabagta SB.
Haddii aad qabto wax su'aalo ah oo ku saabsan SF laminating ee baakadaha dabacsan, waxaan diyaar u nahay inaan ku caawinno.
