I-PVC Flexible Banner Production Process Analysis
Iibhena eziguquguqukayo zePVC zisetyenziswa ngokubanzi kwiintengiso, kuyilo lomsitho, kunye namanye amabala ngenxa yokuguquguquka okugqwesileyo, ukumelana nemozulu, kunye nokubhenela okubonakalayo. Inkqubo yokuvelisa ibandakanya amanyathelo amaninzi, efuna ulawulo olungqongqo lokukhethwa kwezinto kunye neeparitha zokucubungula ukuqinisekisa umgangatho wemveliso.
Ukulungiswa kwezinto ezikrwada linyathelo lokuqala kwimveliso. -umgangatho ophezulu wepolyvinyl chloride (PVC) resin yenza i-core substrate. I-Plasticizers, i-stabilizers, kunye nee-pigments zongezwa ngokusekelwe kwi-flexibility efunwayo kunye nokuqina kwebhanari. Umxholo we-plasticizer uchaphazela ngokuthe ngqo iimpawu ze-flexural zePVC. Okuphezulu -imixube ebhetyebhetye idla ngokusetyenziswa ukuqinisekisa ukuba ibhanile ihlala ibhetyebhetye kwaye iyaxhathisa ukuqhekeka nakwimekobume zobushushu obuphantsi{6}. I-UV{8}}izongezo ezixhathisayo zikwaphucula ukuxhathisa kwemozulu yangaphandle, ukunqanda ukufiphala nokuguga.
Ukuxuba kunye ne-extrusion ziinkqubo eziphambili. Iimathiriyeli ekrwada ezilungelelaniswe ngononophelo zongezwa-kumxube wesantya esiphezulu, apho zithi zisasazwe ngokufanayo ngobushushu kunye nokuchetywa koomatshini. Izinto ke zingena kwi-twin - screw extruder, apho inyibilikiswa kwaye yenziwe ngeplastiki kumaqondo obushushu aphezulu (malunga ne-160-180 degree) kwaye ikhutshwe ngefa elikhethekileyo kwifilimu eqhubekayo. Ngeli nqanaba, ukulawulwa ngokuchanekileyo kweqondo lokushisa kunye nesantya sokutsala kuyadingeka ukukhusela ukubola kwezinto ngenxa yokushisa okanye uxinzelelo lwangaphakathi olubangelwa ukugqithisa.
Ushicilelo kunye nokwaleka lunika umzobo kunye neempawu zokukhusela kwibhena. I-inkjet yedijithali okanye ushicilelo lwesikrini lusetyenziselwa ukudlulisa uyilo kwindawo yePVC. I-inki kufuneka ibe nokubambelela kakuhle kunye nokumelana nokukrazuka. Ezinye iimveliso zigqunywe ngoluhlu olongezelelweyo olukhuselayo (njenge-UV ivanishi) ukunyusa ukuxhathisa kwamanzi kunye nokuxhatshazwa kwe-abrasion. Kwizicelo ezifuna ukuguquguquka okukhulu, i-micro{4}}yonyango oluphezulu lwesicatshulwa lunokusetyenziswa ukunciphisa umngcipheko wokuqhekeka ngexesha lokugoba.
Ukusika kunye nokwenza ngamanyathelo okugqibela. Ngokusekwe kwiimfuno zabathengi, umqulu wefilimu yePVC ucandwa ngokobungakanani obuthile kwaye emva koko ubushushu -icinezelwe okanye ibandayo{2}}inqunyulwe ukwenza imiphetho egoso okanye ezinye izinto{3} ezimile okwesiqhelo. Imveliso egqityiweyo iphantsi kolawulo olungqongqo lwekhwalithi, kubandakanya uvavanyo lokuguquguquka, uvavanyo lokukhawuleza kombala, kunye nokuqinisekiswa kokunyamezela, ukuqinisekisa ukuthotyelwa kwemigangatho yoshishino.
Ukuveliswa kweebhena eziguquguqukayo ze-PVC zidibanisa isayensi yezinto kunye neteknoloji yokuvelisa ngokuchanekileyo. Ngokulungisa iiparameters zokuqulunqa kunye nenkqubo, isiphumo siyindlela yokukhangisa edibanisa i-aesthetics, ukuqina, kunye nokuguquguquka.
