Ngokuthuthuka okuqhubekayo kwemboni yepulasitiki, amapulasitiki engcosa amandla abangela ukulimala okungaba khona nokungathí sina emvelweni. Ukuvuselelwa, ukwelashwa, kanye nokuphinda usebenzise kabusha kwamapulasitiki sekube ukukhathazeka okuvamile empilweni yabantu. Njengamanje, ukuphathwa okuphelele kokubuyiselwa kokululama nokuphinda usebenzise kabusha amapulasitiki asephenduke kube yinkinga ephuthumayo kakhulu okufanele ixazululwe.
Nalu uhlu lokuqukethwe:
Zithini ukuhlukaniswa kwamapulasitiki?
Imishini yokuvuselela kabusha ipulasitiki ihlukaniswa kanjani?
Kuyini ukugeleza kwenqubo yomshini wokuphinda usebenzise ipulasitiki?
Zithini ukuhlukaniswa kwamapulasitiki?
Kunezindlela eziningi zokuhlukaniswa kwamapulasitiki. Ngokusho kwezindawo ezahlukahlukene zomzimba nezamakhemikhali, amapulasitiki afaka amapulasitiki we-thermoset kanye nama-thermoplastics. Ngokusho kwesilinganiso sohlelo lokusebenza samapulasitiki, amapulasitiki angahlukaniswa izigaba ezintathu: I-General Plastics, amapulasitiki wobunjiniyela, namapulasitiki akhethekile.
1. I-General Plastics
I-plastics okuthiwa yi-General-Inhloso ibheka kulabo abasetshenziselwa ukukhiqizwa kwesisindo semikhiqizo yezimboni. Banokwakheka okuhle nentengo ephansi. Kubandisa iningi lokusetshenziswa kwezinto zokwakha zepulasitiki.
2. I-Engineering Plastics
Ubunjiniyela be-Plastics banezakhiwo ezinhle zemishini, ukuqina okuhle kobukhulu, ukumelana okushisa okuphezulu, nokuphikiswa kokugqwala kwamakhemikhali. Zisetshenziswa ikakhulukazi ezakhiweni zobunjiniyela. Njenge-polyamide, i-polylulfone, njll. Ingasetshenziswa kabanzi kwizidingo zansuku zonke, imishini, kanye nezimboni ze-elekthronikhi.
3. Amapulasitiki akhethekile
Amapulasitiki akhethekile abhekisela kumapulasitiki anemisebenzi ekhethekile futhi angasetshenziswa emasimini akhethekile. Amapulasitiki akhethekile anjengamapulasitiki aphaselayo, amapulasitiki anamandla okusebenza, kanye nama-fluororolastics, phakathi kwama-fluoroplastics anezimpawu ezinhle kakhulu zokuzithambisa kanye nokumelana okushisa kakhulu.
Imishini yokuvuselela kabusha ipulasitiki ihlukaniswa kanjani?
Umshini wokuvuselelwa kabusha kwepulasitiki yigama elijwayelekile lochungechunge lweplastiki yepulasitiki kanye nokuphinda usebenzise kabusha amapulasitiki, njengokuhlonza, ukuchithwa, ukuhlanza, ukuwohloka, ukukhishwa, ukukhishwa, ukukhishwa kwe-wire, ukukhishwa kwentambo, ukukhiqizwa, njalonjalo. Akubhekiseli kuphela emshinini othize kepha isifinyezo semishini yokuvuselela kabusha imfucuza, kufaka phakathi imishini yokuhlekisa kanye nemishini yokuphinda usebenzise kabusha. Imishini yokuhlekisa ihlukaniswe i-crusher yepulasitiki, umenzeli wokuhlanza upulasitiki, i-dehydrator yepulasitiki, neminye imishini. I-Granution Equipment nayo ihlukaniswe ngama-extuders epulasitiki kanye ne-pelletizer epulasitiki.
Kuyini ukugeleza kwenqubo yomshini wokuphinda usebenzise ipulasitiki?
Umshini wokuphinda usebenzise imfucumfucu kabusha ngumshini wokuphinda usebenzise kabusha ofanele impilo yansuku zonke namapulasitiki wezimboni. Ukugeleza kwenqubo kuqala ukubeka kuqala amapulasithi kadoti ku-hopper futhi kuthuthe izinto zokwakha zichotshozwe kwibhande lokuhambisa liye ku-crusher yepulasitiki. Emva kwalokho, izinto zokwakha zicutshungulwa kuqala ngokuchotshozwa, ukugeza amanzi, nezinye izindlela zokwelapha, kanye nezinto zokwelashwa ezichotshoziwe zizodlula ezingxabanweni zokuhlanza ngokuhlanza okuqinile. Ngokulandelayo, ithangi elicwengezelayo lizohlanza izingcezwana zepulasitiki zokususa ukungcola, futhi okuqukethwe kuzothunyelwa ethangi lokuwasha kusixhumanisi esilandelayo sokuvuna futhi. Emva kwalokho, ithuba lokumisa alona amanzi alonakalisayo futhi lisoma izinto zokuhlanza, kanye nethuba lokudla okuzenzakalelayo lizothumela izinto ezizothunyelwa emshinini omkhulu we-granulator yepulasitiki ngendlela ehlelekile. Ekugcineni, i-granulator yepulasitiki ingalimaza lokho okuqukethwe, futhi ithangi elipholile lizopholisa umucu wepulasitiki olwedlulela ekufeni. I-granulator yepulasitiki ilawula usayizi wezinhlayiya zepulasitiki ngokulawulwa kokuguqulwa imvamisa.
Njengamanje, ukusetshenziswa kwamapulasitiki kukhulu emhlabeni wonke. Izindlela zokwelashwa zendabuko zokugunda kanye nokugcwaliswa komhlaba kwamapulasitiki angcolile azilungele isimo samanje sokuthuthukiswa komhlaba. Ngakho-ke, lapho sisebenzisa imikhiqizo yepulasitiki ukuletha lula isintu sethu, nathi kudingeka futhi sicabange kabanzi ngokuthi ungabuyisela kanjani kabusha amapulasitiki asetshenzisiwe. Kusukela yasungulwa ngo-2018, iSuzhou Poly Machinity Co, Ltd yathuthuka yaba yinye yezisekelo zokukhiqiza izingqimba ezinkulu zaseChina futhi yanqwabelana iminyaka eminingi yesipiliyoni embonini yepulasitiki. Uma ubandakanyeka ekushintsheni kwepulasitiki edoti noma unenhloso yokuthenga, ungaqonda futhi ucabangele imikhiqizo yethu esezingeni eliphakeme.
