Inani elincane loku-oda liyahlukahluka ngezinga nangendlela yokupakisha, futhi ngokuvamile liyaguquguquka ezintweni ezisemtholampilo ezijwayelekile. Ukuthwala amakhontena agcwele kunikeza intengo enhle kakhulu ngeyunithi ngayinye, kodwa i-Mier iphinde isekele ama-oda amancane okuzama kanye nokuphinda okwamakhasimende asathuthukayo. Isikhathi sokulinda samazinga e-LDPE asemtholampilo ngokuvamile sifushane, kuyilapho izinhlanganisela ezenziwe ngokwezifiso zidinga isikhathi esengeziwe sokukhiqiza nokuhlola. Isikhathi sokulethwa siphinde sincike echwebeni lomgomo wokufika, uhlelo lomzila wemikhumbi, kanye nezinqubo zentela ezweni lomthengi. Ithimba lokuthengisa liqinisekisa isikhathi sokulinda esiqinile ekwamukelweni kwe-oda futhi linikeza izibuyekezo phakathi nakho konke ukukhiqiza. Kunconywa ukuhlela kusenesikhathi ngezikhathi zamathemu aphezulu ngoba isidingo se-polyethylene somhlaba wonke singathinta ukutholakala.

Yebo, ama-pellets e-LDPE agaywe kabusha ayingxenye yomkhiqizo ojwayelekile futhi asekela kokubili ukuncishiswa kwezindleko kanye nezinjongo zemvelo. Lawa magreddi akhiqizwa nge-feedstock ehlungiwe yangemva kwezimboni kanye nangemva kokusetshenziswa ngabathengi, bese ihlungwa futhi ihlanganiswe ukuze kube nokucubungula okungaguquguquki. Angahlinzekwa ngesimo semvelo, esinombala, noma esimnyama kuye ngokuthi uhlelo lokusetshenziswa kanye nezidingo zokubukeka. I-Mier iphinde iphathe izinto ze-PCR ezinobungani nemvelo kwezinye imindeni yama-polymer kubathengi abakha imigqa yemikhiqizo esimeme ebanzi. Abasebenzi bezobuchwepheshe bangasiza ekunqumeni ukuthi ingabe igreddi egaywe kabusha ifanele uhlelo oluthile lokusetshenziswa noma ingabe ingxubevange ene-virgin resin ifaneleka kakhulu. Izinjongo zokusimama ngokuvamile zingafinyelelwa ngaphandle kokubeka engcupheni ukusebenza kwemishini okudingwa umkhiqizo wokugcina.

Ukungaguquguquki kwekhwalithi kuvikelwe ngezinqubo ezibhaliwe kuzo zonke izigaba, kusukela ekuqinisekisweni kwezinto zokusetshenziswa ezifikayo kuze kufike ekuhlolweni kokugcina kokuthunyelwa. I-batch ngayinye ihlolwa nge-melt flow index, density, tensile strength, elongation, kanye nokubukeka ngaphambi kokukhishwa. Amapharamitha okukhiqiza ayarekhodwa, futhi izimpahla eziqediwe zinezinombolo ze-batch ezixhumeka ngqo kumarekhodi aselabhorethri. Izinhlelo zokuphatha ezihambisana ne-ISO zilawula ukulawulwa kwemibhalo, isenzo sokulungisa, kanye nokuthuthukiswa okuqhubekayo. Uma ikhasimende libika inkinga, uhlelo lokulandelela luvumela ithimba lobuchwepheshe ukuthi likhombe i-batch futhi lihlaziye imbangela ngokushesha. Le ndlela eqondile iyisizathu esenza ukuthi i-Mier ikwazi ukuhlinzeka ngama-oda aphindwayo aziphatha ngendlela efanayo emishinini yekhasimende njalo.

Uma usukulungele ukuqhubekela phambili, indlela esheshayo ukucela isilinganiso sentengo, ishidi ledatha lobuchwepheshe, noma isampula lamahhala ku-Mier Plastic Material Co., Ltd. Ukwabelana ngohlelo lwakho lokusebenza, uhlobo lomshini, izicaciso okuhlosiwe, kanye nevolumu elindelekile kuvumela ithimba ukuthi lincomende igredidi elifanele ngokushesha. Izidingo ze-LDPE yesiko zingaxoxwa ngqo nethimba lobuchwepheshe, kufaka phakathi i-melt flow index, ukuminyana, umbala, kanye nokulungiswa kwezithako. Abathengi abadinga i-LDPE kanye ne-TPU, TPE/TPR, PA, PC, noma izinto ze-PCR bangahlanganisa ukuthengwa futhi benze lula uchungechunge lwabo lokuhlinzeka. Ikhathalogi ephelele yenkampani kanye nephrofayili yenkampani kuyatholakala nge-Ikhaya ikhasi, lapho imikhiqizo, izinhlelo zokusebenza, izitifiketi, nezindaba zihlelwe ukuze zibuyekezwe kalula. Hlanganyela ne-Mier Plastic ukuze uthole ukunikezwa kwe-LDPE okuthembekile, amanani ancintisanayo, nokusekelwa kwezobuchwepheshe okuqhubeka isikhathi eside ngemva kokufika komthwalo wokuqala.
