Lapho wenza ngokwezifiso ukupakishwa kwezimonyo, ukukhetha kwezinto kudlala indima ebalulekile ekuqinisekiseni ikhwalithi, ukuqina, nokukhanga kobuhle bomkhiqizo wokugcina.
Phakathi kwezinketho ezihlukahlukene ezitholakalayo, i-PCTG (i-polycyclohexanedimethyl terephthalate) isibe yisinqumo esithandwayo sokupakishwa kwezimonyo njengoba inenhlanganisela eyingqayizivele yezakhiwo ezenza ilungele lolu hlelo lokusebenza oluthile.
Kulesi sihloko, sizongena emhlabeni wobunjiniyela bepulasitiki namapulasitiki enhloso evamile, bese sihlola ukuthi kungani i-PCTG ivame ukukhethwa lapho kwenziwa ngendlela oyifisayo ukupakishwa kwezimonyo.
PC (polycarbonate), PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene), PA (polyamide), PBT (polybutylene terephthalate), POM (polyoxymethylene), PMMA (polymethyl methacrylate), PG/PBT (polyphenylene ether/polybutylene) zaziwa ngezakhiwo zazo ezinhle kakhulu zemishini, ezishisayo namakhemikhali.
Lezi zinto zisetshenziswa ezimbonini ezahlukahlukene ezihlanganisa ezezimoto, ezogesi kanye nemikhiqizo yabathengi ngenxa yokusebenza kwazo okuphezulu nokuhlukahluka.
Ngakolunye uhlangothi, amapulasitiki enhloso ejwayelekile njenge-PP (i-polypropylene), i-PE (i-polyethylene), i-ABS (i-acrylonitrile butadiene styrene), i-GPPS (i-polystyrene yenjongo evamile), ne-HIPS (i-polystyrene enomthelela ophezulu) asetshenziswa ngenxa yokonga kwawo. Yaziswa ngezakhiwo zayo kanye nokulula kokucutshungulwa kwayo, futhi inezinhlobonhlobo zezinhlelo zokusebenza.
Emkhakheni werabha yokwenziwa, i-TPU (i-thermoplastic polyurethane), i-TPE (i-thermoplastic elastomer), i-TPR (irabha ye-thermoplastic), i-TPEE (i-thermoplastic polyester elastomer), i-ETPU (i-ethylene thermoplastic polyurethane), i-SEBS (i-styrene ethylene butylene styrene) nezinye i-TPX (i-polymethylpentene) zaziwa ngokunwebeka kwazo, ukumelana nokuhuzuka kanye nokumelana nomthelela.
Lezi zinto zithola ukusetshenziswa ezimbonini ezifana nezicathulo, imishini yezemidlalo kanye nemishini yezokwelapha, lapho ukuguquguquka nokuqina kubaluleke kakhulu.
Manje, ake sibhekise ukunaka kwethu ku-PCTG, ipulasitiki yobunjiniyela edonse ukunaka emkhakheni weukwenza ngokwezifiso ukupakishwa kwezimonyo. I-PCTG iyi-copolyester enenhlanganisela eyingqayizivele yezakhiwo ezenza ilungele izinhlelo zokusebenza ezidinga ukucaciseleka, ukumelana nomthelela kanye nokuhambisana kwamakhemikhali.
Enye yezinto ezibalulekile ze-PCTG ukubonakala kwayo okukhethekile, engasetshenziswa ukwakha amaphakheji abonisa ngale noma akhanyayo aveza umbala nokuthungwa komkhiqizo wezimonyo ngaphakathi.
I-Optical transparency isici esifiseleka kakhulu ekufakweni kwezimonyo ngoba kuvumela abathengi ukuthi babone okuqukethwe kwephakheji, ngaleyo ndlela kuthuthukise ukubukeka komkhiqizo.

Ngokungeziwe ekukhanyeni kwayo, i-PCTG inikeza ukumelana nomthelela omuhle kakhulu, okuyenza ilungele ukupakishwa kwezimonyo okudinga ukuphathwa, ukuthunyelwa, nokugcinwa. Lesi sici siqinisekisa ukuthi iphakheji igcina ubuqotho bayo kanye nobuhle ngisho nangaphansi kwezimo ezinzima.
Ukwengeza, i-PCTG imelana nohlu olubanzi lwamakhemikhali, kufaka phakathi izithako ezivamile zezimonyo, ukuqinisekisa ukuthi ukupakishwa kuhlala isikhathi eside futhi akuthinteki okuqukethwe kwayo. Lokhu kumelana namakhemikhali kuyisici esibalulekile ekugcineni ikhwalithi nokubukeka kwezimonyo ngokuhamba kwesikhathi.
Esinye isici esihlukanisayo se-PCTG ukucutshungulwa kwayo, okuvumela ukudalwa kwemiklamo eyinkimbinkimbi futhi enhle emaphaketheni wezimonyo.
Kungakhathaliseki ukuthi ukubunjwa kobunjwa obuyinkimbinkimbi, inhlanganisela yokugqamisa noma izici zokugqamisa, noma ukungezwa kwezakhi zokuhlobisa, i-PCTG ifaneleka kahle ukwenziwa ngokwezifiso kokupakishwa kwezimonyo, okuvumela imikhiqizo ukuthi yenze imikhiqizo eyingqayizivele nebukekayo egqama emakethe. .
Ukwengeza, i-PCTG ingaba nombala kalula, inikeze ukuguquguquka kuidizayini nezinketho zokufaka uphawu lokwenza ngokwezifiso ukupakishwa kwezimonyo.
Ukusetshenziswa kwe-PCTG ekufakweni kwezimonyo kudlulela emikhakheni ehlukahlukene yemikhiqizo njengokunakekelwa kwesikhumba, ukunakekelwa kwezinwele, izimonyo, namakha. Kusukela emabhodleleni nezimbiza kuya kuma-compact kanye namabhokisi e-lipstick, i-PCTG ingasetshenziswa ukudala izixazululo ezihlukahlukene zokupakisha ukuhlangabezana nezidingo ezithile kanye nokuthandwa ngabathengi.
Noma ngabe ukucwebezela, ukubukeka kwesimanje kwebhodlela le-PCTG elicacile lamaserum okunakekelwa kwesikhumba okunethezeka noma ukugqama okuhle kwe-PCTG compact yesisekelo esisezingeni eliphezulu, ukuguquguquka kwe-PCTG kukuvumela ukuthi udale amaphakheji afana nesithombe somkhiqizo wakho kanye nokuma komkhiqizo.
Ukuhambisana kwe-PCTG nezindlela ezihlukahlukene zokuhlobisa njengesikrini sikasilika, ukugxiviza okushisayo kanye nokulebula okungaphakathi kwesikhunta kuthuthukisa ukukhanga okubonakalayo kokupakishwa kwezimonyo, okuvumela amabhrendi ukuthi athuthukise ikhwalithi yemikhiqizo yawo ngemiklamo eyenziwe ngokwezifiso, amalogo nemifanekiso.
Leli khono lokwenza ngokwezifiso libaluleke kakhulu endaweni yokuncintisana yemboni yezimonyo, lapho imikhiqizo ilwela ukuhlukanisa imikhiqizo yabo kanyedala isithombe esiqinile somkhiqizo ngomklamo wokupakisha.
Ikhethelwe ukupakishwa kwezimonyo ngokwezifiso ngenxa yenhlanganisela yayo eyingqayizivele yezakhiwo, okuhlanganisa ukubonakala obala okuphakeme, ukumelana nomthelela, ukuhambisana kwamakhemikhali, ukucutshungulwa kanye namandla okwenza ngokwezifiso. Lezi zakhiwo zenza i-PCTG ibe into efanelekile yokwakha izixazululo zokupakisha ezingavikeli kuphela futhi zilondoloze izimonyo, kodwa futhi ezithuthukisa ukukhanga kwazo okubonakalayo nokuthengiseka.
Njengoba isidingo sokupakishwa kwezimonyo ezintsha nokubonakalayo sikhula, i-PCTG iba inketho eguquguqukayo nethembekile yemikhiqizo efuna ukushiya umbono ohlala njalo embonini yobuhle.
