Edemede a na-enyocha ihe mgbagwoju anya nke akwụkwọ akụkọ anyịrPET granulating akara, ihe ngwọta emebere nke ọma iji kwalite arụmọrụ na ịdị mma nke mmepụta pellet PET megharịrị.
Kpọọ & kristalize n'otu nzọụkwụ, imeghe arụmọrụ:
Nkà na ụzụ mgbanwe anyị na-ewepụ mkpa nke ihicha dị iche iche na ọkwa crystallization, na-eme ka usoro ahụ dịkwuo mma ma na-ebelata oriri ike.Usoro otu nzọụkwụ a na-enweta mmiri ikpeazụ n'okpuru 30ppm n'ime nkeji 20, na-ebelata ọnụ ahịa ume ike (0.06-0.08kwh/kg) ma e jiri ya tụnyere usoro omenala.Ọzọkwa, njupụta flake na-abawanye site na 15-20%, na-akwalite arụmọrụ nri extruder.
Na-echekwa viscosity dị n'ime, na-ejigide ogo:
Infrared tupu ihicha na-arụ ọrụ dị oke mkpa n'ichekwa viscosity intrinsic (IV) nke rPET, ihe dị mkpa maka ngwa ọkwa nri.Site n'ibelata ikpughe PET na mmiri n'oge extrusion, mmebi IV dị oke, na-ahụ na ịdị mma na resin resin.Na mgbakwunye, oge ihicha dị mkpụmkpụ (nkeji 15-20) na-egbochi ịcha edo edo nke ibe agbaze, na-ejigide ọmarịcha ngwaahịa.
Mbupụta abawanyela, arụmọrụ emelitere:
Site na ikpo ọkụ flakes, usoro IRD na-ebelata nrụgide ịkpachasị ahụ n'ime extruder, na-eme ka okpomọkụ na-adị mgbe niile ma na-eme ka ọ dị elu extrusion ọsọ.Nke a na-atụgharị na mmụba dị ịrịba ama na ikike ahịrị mmepụta, ruo 50% n'ọnọdụ ụfọdụ.Na mgbakwunye, arụmọrụ nri emelitere yana mbelata nhụta viscosity na-enye aka na usoro mmepụta kwụsiri ike na nke a na-ahụ anya.
Ọrụ dị mfe, mbelata ọnụ ahịa:
Nke a rPET granulating ahịrị na-anya isi atụmatụ enyi na ọrụ dị mfe.Ejiri sistemụ Siemens PLC nwere ọrụ ebe nchekwa otu igodo, ahịrị ahụ na-eme ka mmalite ngwa ngwa na mechie ngwa ngwa, na-ewepụ mkpa ọ dị tupu ikpo ọkụ.Nha kọmpat na mmezi dị mfe na-abawanye arụmọrụ arụmọrụ.
Uru na nlele:
Mbelata n'ichepụta ọnụ ahịa: Ruo 60% obere ike oriri ma e jiri ya tụnyere usoro ihicha ọdịnala.
Mmalite ngwa ngwa na nkwụsị ngwa ngwa: Ọ dịghị mkpa maka ikpo ọkụ tupu.
Ọrụ dị mfe: ihicha otu nzọụkwụ na kristal, Siemens PLC dị mfe iji.
Mmụba mmepụta ikike: Ruo 50% mmụba.

Itinye ego n'ọdịniihu nke mmepụta rPET:
Ahịrị granulating rPET ọhụrụ a na-anọchite anya ọganihu dị ịrịba ama n'ọhịa nke imegharị plastik.Site n'inye arụmọrụ dị elu, ogo ngwaahịa dị mma, yana ibelata oriri ume, ọ na-enye ndị nrụpụta ike imezu ebumnuche nkwado ha ka ha ka na-asọmpi n'ahịa.Teknụzụ a na-emeghe ụzọ maka ọdịnihu ga-adigide maka ụlọ ọrụ plastik, na-akwalite akụ na ụba okirikiri ma na-enye aka na mbara ala dị ọcha.
