Ukuqothulwa ukusebenzisa izindlela ezithile zokunciphisa ukucwebezela kwendawo enamathelayo.
1. isimiso sokushabalala
Kuhlanganiswe nendlela ye-gloss ebusweni befilimu kanye nezici ezithinta isicwebezelisi, abantu bakholelwa ukuthi ukushabalala kuwukusebenzisa izindlela ezihlukahlukene ukuze kucekelwe phansi ubushelelezi befilimu, kwandise ukuhwaqeka okuncane okungaphezulu kwefilimu, nokunciphisa ukubukeka kwefilimu. ukukhanya.Ingahlukaniswa ngokushabalala komzimba kanye nokushabalala kwamakhemikhali.Umgomo wokulinganisa ngokomzimba uwukuthi: engeza i-ejenti yokuhlanganisa ukuze wenze ubuso be-coating bungalingani enqubweni yokwenza ifilimu, ukwandisa ukuhlakazeka kokukhanya nokunciphisa ukucabangela.Ukushabalala kwamakhemikhali ukuthola isicwebezelisi esiphansi ngokwethula ezinye izakhiwo ezimunca ukukhanya noma amaqembu afana nezinto ezixhunywe nge-polypropylene kuma-UV.
2. indlela yokushabalala
I-ejenti yokukhwelana, embonini yanamuhla yokuhlanganisa i-UV, abantu ngokuvamile basebenzisa indlela yokwengeza i-ejenti yokukhwelana.Kukhona ikakhulukazi izigaba ezilandelayo:
(1) Insipho yensimbi
Insipho yensimbi iwuhlobo lwe-ejenti yokuhlanganisa evame ukusetshenziswa abantu bokuqala.Ikakhulukazi i-metal stearate, njenge-aluminium stearate, i-zinc stearate, i-calcium stearate, i-magnesium stearate nokunye.I-aluminium stearate isetshenziswa kabanzi.Isimiso sokuqothulwa kwensipho yensimbi sisekelwe ekungahambelani kwayo nezingxenye zokumboza.Imisiwe ekugqokeni ngezinhlayiya ezinhle kakhulu, ezisatshalaliswa ebusweni be-coating lapho ifilimu kwakhiwa, okuholela ekuqineni okuncane ebusweni be-coating futhi kunciphise ukubonakaliswa kokukhanya ebusweni be-coating ukuze kuzuzwe. inhloso yokushabalala.
(2) Ingcina
I-Wax iyi-ejenti yokumathisa yangaphambili futhi esetshenziswa kabanzi, engeye-organic suspension matting agent.Ngemuva kokwakhiwa kwe-coating, nge-volatilization ye-solvent, i-wax efilimu yokugqoka ihlukaniswa futhi imisiwe phezu kwefilimu yokugqoka ngamakristalu amahle, okwenza ungqimba olukhanyayo oluhlakazekile ebusweni futhi idlala indima yokuqothulwa.Njenge-ejenti yokuhlanganisa, i-wax kulula ukuyisebenzisa, futhi inganikeza ifilimu umuzwa omuhle wesandla, ukumelana namanzi, ukumelana nomswakama nokushisa, nokumelana namabala.Kodwa-ke, ngemva kokuba ungqimba lwe-wax lwenziwe endaweni yefilimu, luzophinde luvimbele ukuvuthwa kwe-solvent kanye nokungena kwe-oksijini, okuthinta ukomiswa nokubuyisela kabusha ifilimu.Umkhuba wokuthuthuka esikhathini esizayo uwukuhlanganisa i-polymer wax ne-silica ukuze kutholwe umphumela wokushabalala ongcono kakhulu.
(3) Izinhlawulo zokusebenza
Imibala ebonakalayo, efana ne-diatomite, i-kaolin ne-silica evuthayo, izinhlawulo ezisebenzayo ezisetshenziswa ngokukhethekile njengama-matting agents.Bangama-agent agcwele ama-matting.Lapho ifilimu yomile, izinhlayiya zazo ezincane zizoba indawo enokumaholoholo endaweni yefilimu ukuze kuncishiswe ukukhazimula kokukhanya futhi zithole ukubukeka kwe-Matt.Umthelela wokuhlanganisa walolu hlobo lwe-ejenti yokukhwelana ukhawulelwe izici eziningi.Uma sithatha i-silica njengesibonelo, lapho isetshenziswa njenge-ejenti yokuhlanganisa, umphumela wayo wokulinganisa uzothintwa yizici ezifana nevolumu yembotshana, isilinganiso sosayizi wezinhlayiyana nokusabalalisa usayizi wezinhlayiyana, ukujiya kwefilimu eyomile kanye nokuthi ingaphezulu lezinhlayiyana selashiwe yini.Ukuhlola kubonisa ukuthi ukusebenza kokushabalala kwe-silica dioxide enevolumu enkulu yembotshana, ukusabalalisa usayizi wezinhlayiyana ezifanayo kanye nosayizi wezinhlayiyana ohambisana nogqinsi lwefilimu elomile kungcono.
Ngokungeziwe ezinhlotsheni ezintathu ezingenhla zama-agent asetshenziswa ngokuvamile, amanye amafutha omile, afana nowoyela we-tung, angasetshenziswa futhi njengama-matting enamathela e-UV.Ikakhulukazi isebenzisa i-reactivity ephezulu ye-conjugated double bond yamafutha we-tung ukwenza phansi kwefilimu kube nesivinini esihlukile se-oxidation ne-cross-linking, ukuze ingaphezulu lefilimu lingalingani ukuze kuzuzwe umphumela wokuhlangana.
