Ukupakishwa kokuTya Umqulu weFilimu wokuPakisha ngokuzenzekelayo kuMashini wokuPakisha iFilimu yePlastiki

Ifilimu edibeneyo eyenziwe kwiileya ezimbini okanye ngaphezulu kufuneka ingabinakwahlulwa njengefilimu enye. Oku kubandakanya okungaphezulu nje kokuncamathelisa phakathi kwezi filimu zimbini. Ikwanxulumene nefilimu ye-inki. Izinto zokuncamathelisa ziimveliso zokwenziwa Uninzi lwezincamathelisi ezincamathelayo zineenxalenye ezimbini zepolyurethane (PU). Ukusabela kweekhemikhali kwenkqubo yokugaya iphilisa i-adhesive. I-adhesive ebusweni be-substrate ikakhulu yinkqubo yomzimba kwaye inxalenye encinci yinkqubo yeekhemikhali. Ngeli xesha, amacandelo e-adhesive adityaniswa kunye namacandelo efilimu yeplastiki kwaye aphiliswe ngakumbi.
Ukuba ifilimu edibeneyo sele ishicilelwe ngexesha lenkqubo yokudibanisa ngoko i-adhesive kunye ne-inki kufuneka ihlangabezane neemfuno ezininzi. Imfuneko esisiseko kakhulu kukuba umaleko wangaphakathi kufuneka ube nokuqina kokubambelela kakuhle kunye nokoma ngaphambi kokulanywa. Oku kuthetha ukuba akukho zintsalela ze-solvent ezivumelekileyo kumgca oprintiweyo. Kodwa isinyibilikisi okanye utywala budla ngokushiywa kumdibaniso we-inki. Ngenxa yesi sizathu, iipropati ze-adhesive kufuneka zikwazi ukubopha kwii-radicals zamahhala (-OH amaqela). Ngaphandle koko, i-adhesive kunye ne-ejenti yokunyanga iya kusabela ngokwazo kwaye ilahlekelwe iimpawu zayo zangaphambili.
Phakathi kwe-adhesives, i-adhesives-based adhesives iyahlula kwii-adhesives ezingenayo i-solvent efana ne-UV. Umxube we-solvent-based drill ufuna itonela yokomisa ukuze uguqule isinyibilikisi. Xa kusetyenziswa izinto zokuncamathelisa ze-UV, ukukhanya kwe-UV kuhamba ngefilimu edibeneyo ukuya kwindawo yokuncamathelisa ukwenza i-polymerize into encamathelayo kunye.
1. Ikhompawundi eyomileyo
Ibhekisela kwindlela apho i-adhesive ihlanganiswe kwimeko eyomileyo. Okokuqala, i-adhesive ifakwe kwi-substrate. Emva kokumisa kwi-tunnel yokumisa, zonke i-solvents kwi-adhesive iyomile. Inkqubo yokunyibilikisa i-adhesive, ukudibanisa enye i-substrate kuyo, ukupholisa, kunye nokunyanga ukuvelisa izinto ezidibeneyo ezineempawu ezintle.
2. Ikhompawundi ye-Extrusion
Ikwabizwa ngokuba yi-casting compounding, enye yeendlela eziphambili zemveliso yokupakishwa okuguquguqukayo. Inyibilikisa i-thermoplastics efana ne-polyethylene kunye ne-polypropylene kumatshini odibanisa i-extrusion, kwaye iphuma ngokufanayo kwifilimu ebhityileyo esuka kwintloko ecaba, kwaye iqhubekile ngokuqhubekayo Kwisiseko sezinto ezisisiseko, ifilimu edibeneyo yemigangatho emibini okanye ngaphezulu yenziwa ngokucinezela kunye. i-roller yoxinzelelo kunye nokupholisa nge-roller yokupholisa.
I-Extrusion lamination ineenzuzo zesantya sokuvelisa ngokukhawuleza, inkqubo yokuvelisa elula, indawo yokuvelisa ecocekileyo, ukusebenza kakuhle kwemveliso, ukusebenza okulula, ixabiso eliphantsi, kwaye akukho ntsalela ye-solvent. indawo ebalulekileyo.
