Emazweni wokupakisha wanamuhla, ukuphrinta, kanye nezinto ezibonakalayo, ishidi elishisa kakhulu lezimboni limi njengekhambi eliguqula umdlalo olishintsha ngendlela elihlukile lokusebenza ngokuqinile, ukuguquguquka kobungani kanye nokuguquguquka. Kufushane kwe-polyethylene terephthalate, i-pet yi-thermoplastic polymer edume amandla ayo nokusimama kwayo, futhi lapho i-njiniyela ibe ngamashidi aphezulu, iba yinto ephakeme ngezicelo zendabuko ezinjengezicelo lapho ukubonakala khona, ukuqina kanye nokusebenza izindleko kubalulekile. Noma ngabe isetshenziselwa ukufakwa kokudla okubonisa imikhiqizo, ama-substrates okuphrinta aphezulu aphezulu, noma izithiyo ezivikela izimboni, amashidi aphezulu wesifo esivela phezulu aletha inani elingenakuqhathaniswa. Lo mhlahlandlela uhlola wonke ubukhulu balokhu okuqukethwe: kusuka ekwakhiweni kwalo kanye nezinto ezibalulekile ezisetshenzisweni zalo ezihamba phambili, amathiphu wokuphatha, izindlela zokulungisa, nokuthi kungani kungukukhetha okuphezulu kwezimboni zokupakisha, ama-elekthronikhi, kanye nokwakhiwa.

　　1. Ithini ishidi eliphakeme lePet Pet.

　　Ngaphambi kokukhetha ezinzuzo zayo, kubalulekile ukuchaza ishidi lesifuba esiphezulu se-pet - ukuthi liyini, senziwa kanjani, nokuthi lihluke kanjani kwezinye izinto ezibonakalayo nokuhlukahluka kwezilwane zasekhaya.

　　1.1 Ukuchazwa kanye nokwakheka kwezinto ezibonakalayo

　　Ishidi elivelayo lePet Petraparency Pet liyi-thermoplable eqinile, eqinile noma eguquguqukayo ye-thermoplay evuthiwe kusuka ku-polyethylene terephthalate (pet), i-polymer ethathwe ku-ethylene glycol ne-terephthalic acid. Ukucaciswa kwayo okucacisiwe okuphezulu - kutholakala ngenqubo eqondile yokukhiqiza enciphisa ukungcola, kunciphisa ukusakazeka kokukhanya, futhi kuqinisekise ubukhulu bomfaniswano. Ngokungafani namashidi ajwayelekile wesikhumba (angaba nokubukeka kancane), ukuhlukahluka okuphezulu okuvuthayo kuyaqhaqhazela ukucaciswa kokukhanya okuqhathaniswa nengilazi, ngamanani aphezulu okuvikela amabanga angu-90% noma ngaphezulu

　　Ukusobala okubonakalayo kuthuthukiswa futhi ngo:

　　I-Low Haze: Ama-Premium High Proprecy Pet amashidi anamanani we-Haze angezansi 2% (Haze ukubhekisela ekusakazweni kokukhanya, okubangela ukubukeka okunamafu). Lokhu kuqinisekisa ukubonakala okubukhali, okucacile kwezinto ezingemuva noma ngeshidi.

　　Ukuqina kwe-UV (kuyakhetheka): Ukuhlukahluka okuningi kuphathwe ngama-UV inhibitors ukuvikela ophuzi noma ukucekelwa phansi ekusetshenzisweni kwelanga, kubenza balungele ukusetshenziswa kwangaphakathi noma isikhathi eside lapho kuvezwa khona lapho kukhanya khona lapho kukhanya khona lapho kukhanya khona ukukhanya.

　　1.2 Inqubo Yokukhiqiza

　　Amashidi aphezulu esitokisini esiphezulu akhiqizwa ngezindlela ezimbili eziyinhloko, ngalinye lihambisana nobukhulu obuhlukile futhi basebenzise amacala:

　　Ukukhishwa: Indlela evame kakhulu yokukhiqiza amashidi amancane aphakathi nendawo (0.1mm kuya ku-5mm). I-petasted petas resin (evame ukuhlanganiswa nama-ejenti acacisa ukukhulisa ukucaca obala) idonswa ngefulethi lifa, bese liphola ngokushesha kuma-roller amnyama ukukhiya ukucaca. Amashidi akwengeziwe angasindi, aguquguqukayo (kuya ngobukhulu), futhi asebenze kahle - elungele ukufakwa, ukuphrinta, kanye nezicelo ezilahlayo.

　　I-Calendering: Isetshenziselwa izinhlayiya, amashidi aqinile (5mm aze afike ku-20mm). Ngemuva kokukhishwa, ishidi lezilwane ezifuywayo lidluliswa ngochungechunge lwama-roller afudumele ukuze abushelelezi ingaphezulu, anciphise ukuhlukahluka kokuqina, futhi athuthukise ukucaca. Amashidi aphezulu entekenteke ethambile anikela ngamafulethi aphakeme kanye nokuqina, abenze balungele izinhlelo zokusebenza ezifana nezimpawu zokubonisa noma izithiyo zokuvikela.

　　1.3 osayizi abajwayelekile, ubukhulu, kanye nokuvumelana nezimo

　　Amashidi aphezulu ethafani eliphakeme atholakala ezinhlotsheni eziningi nobukhulu ukuze ahambisane nezidingo ezahlukahlukene zephrojekthi:

　　Izinketho Zobunzima

　　Ubukhulu buthinta ngokuqondile ukuguquguquka kwephepha, amandla, kanye nokusebenzisa amacala. Izinketho ezijwayelekile zifaka:

　　I-Ultra-mncane (0.1MM kuya ku-0.5mm): I-Flexible, amashidi angasindi kahle alungele ukupakisha (isb.

　　Mncane (0.5mm kuya ku-2mm): Amasheya aqinile afanelekile ukuphrinta (isb.

　　I-Medium (2mm kuya ku-5mm): Amashidi aqinile asetshenziselwa ukuboniswa, ama-point-of-point (pop) ekhombisa, noma izithiyo ezivikelayo (isb.

　　Ubukhulu (5mm kuya ku-20mm): Amashidi aqinile asebenza ngokuqinile ezinhlelweni zesakhiwo ezifana namacala okubonisa ngokwezifiso, onogada bezimboni, noma izibonakaliso zangaphandle.

　　Osayizi abajwayelekile

　　Amasayizi amancane aphakathi nendawo: amasentimitha angama-8x10, amasentimitha ayi-12x12, amasentimitha angu-18x24-alungele ukuphrinta okuncane, amaphrojekthi wezandla, noma ababoniswayo.

　　Amasayizi amakhulu: amasentimitha angama-24x36, amasentimitha angama-36x48, ama-intshi angama-48x72 afanelekile ukuphrinta okukhulu kwefomethi, ukuboniswa kwezitolo, noma amaphaneli wezimboni.

　　Ama-Rolls: Ngezinhlelo zokusebenza zevolumu ephezulu (e.g., Ukupakisha, Ukufakwa Kwamalebula)

　　Ukuvumelana nezimo

　　Ngokungafani nezinto zokwakha eziqinile njengengilazi noma ama-acrylic athambile, amashidi aphezulu wesilwane esiphakeme anikela ngokuguquguquka okuguquguqukayo:

　　Amashidi amancanyana (≤2mm): avumelana nezimo kakhulu, angagoqa noma agoqele ngaphandle kokuqhekeka - elungele izinhlelo zokusebenza ezidinga ukuthuthumela (isb.

　　Amashidi amancanyana (> 2mm): aqine, ukugcina ukwakheka kwawo ngaphansi kwengcindezi ekhanyayo - efanelekele izinhlelo zokusebenza ezihlelekile noma zomthwalo.
