Ngelixa iglasi yayiyeyona nto iphambili yebhotile kule nkulungwane idlulileyo, ukusukela ngasekupheleni kweminyaka yoo-1980, iPET iye yathandwa kakhulu ngabavelisi kunye nabathengi.Ezi bhotile "zepolyester" zinenzuzo ekhethekileyo yokuba zikhaphukhaphu kwaye zingenakophuka.Nangona kunjalo, impumelelo iza nemiceli mngeni emitsha eyayanyaniswa nokurisayiklishwa konyaka kweebhiliyoni zeebhotile ezilahliweyo.
Ukuguqula iibhotile ezisetyenzisiweyo zibe yimathiriyeli ekrwada enokusetyenziswa kufuna ikhonkco elide kunye nenkqubo entsonkothileyo.Konke kuqala ngokuqokelela iibhotile kwaye uzicinezele kwiibhali.Emva koko, iibhali zivuliwe, zihlulwe kwaye zityunyuzwe.Iiflakes ezibangelwayo zihlanjululwa (zibanda kwaye zishushu) kwaye zihlulwe kwi-polyolefin kwi-lid kunye ne-liner.Emva kokumisa kunye nokwahlula isinyithi, iiflakes zinokupakishwa kwii-silos okanye iingxowa ezinkulu.Umjikelo omtsha uyaqala.
Enye yeenkqubo eziphambili zokufumanaI-polyester esetyenzisiweyo kukujikeleza kwemicu emifutshane,enokusetyenziswa, umzekelo, kwi-spinning, i-textile fillers okanye i-nonwovens.Ezi zicelo zisekwe kakuhle, kunye neehempe zoboya kunye neetyali ziyimizekelo ephambili.
Ukongeza, ukuqokelelwa kunye nokuhlaziywa kweebhotile zeplastiki kuyanda kwihlabathi jikelele ngenxa yezinto ezininzi.Ke lixesha lokuphonononga iindlela ezintsha zokusetyenziswa kwe-PET ehlaziyiweyo.
Iintsinga ze-PET zibonelela ngeenzuzo ezininzi xa zisetyenziswa kwiikhaphethi, kubandakanywa ukuxhathisa okuphezulu kwamabala, nokuba ngcono kune-PA BCF ephathwe ngemichiza.Ukongeza, i-PET inokubunjwa ingadayyi, ngelixa i-PP ingenako.Umsonto ongadaywanga unokujijwa, ufakwe ubushushu, udaywe kwaye uthungwe, okanye ikhaphethi egqityiweyo inokuprintwa.
Iukuveliswa kweefilaments eziqhubekayoukusuka kwi-R-PET ikwangumngeni ngakumbi kunokuveliswa kweentsinga ezimfutshane.Kwiukujikeleza kwemicu, umgangatho womsonto unqunywe yi-homogeneity yezinto eziluhlaza.Iiflakes ezifunyenweyo ziyinto ephazamisayo kwaye ukuphambuka okuncinci kumgangatho kunokukhokelela ekwandeni kweengcingo eziphukileyo okanye iingcingo eziphukileyo.Kwakhona, umahluko kumgangatho weflake unokuchaphazela ukufunxwa kombala weentambo, okukhokelela kwimitya kwikhaphethi egqityiweyo.
Iiflakes ze-P-PET ezihlanjiweyo zomiswa kwaye zicocwe kwi-reactor, zinyibilike kwi-extruder kwaye zidlule kwisihluzo sendawo esikhulu sobuhle obahlukeneyo.Ukunyibilika komgangatho ophezulu emva koko kudluliselwe kwinkqubo yokusonta.Iipakethi zokusonta ezikumgangatho ophezulu, ii-double-hull pull rolls, iisistim ze-HPc texturing, kunye nee-winder drives ezine-wheel drives zenza imisonto kwaye zijijelwe kwi-spools.Ngokomenzi, umgca wemveliso yeshishini sele usebenza ngempumelelo ePoland.
