Singabona njalo abantu begaya kabusha amabhodlela epulasitiki, kodwa uyazi ukuthi ayaphi la mabhodlela epulasitiki agaywe kabusha?Eqinisweni, imikhiqizo eminingi yepulasitiki ingabuyekezwa kabusha, futhi ngochungechunge lwezindlela, ipulasitiki ingasetshenziswa kabusha futhi iguqulwe ibe imikhiqizo emisha yepulasitiki noma okunye ukusetshenziswa.Manje kwenzekani kulawa mapulasitiki agaywe kabusha?Ekugcineni, ipulasitiki izobuyela ngayiphi indlela ekuphileni kwethu?Kulolu shicilelo sikhuluma ngokugaywa kabusha kwepulasitiki.
Lapho inani elikhulu lepulasitiki lithuthwa lisuka kuwo wonke amagumbi omphakathi liyiswa esitshalweni sokugaywa kabusha, into yokuqala okudingeka lidlule kuyo ukususa uchungechunge lwezinto ezingahlangene nepulasitiki, njengamalebula, izivalo, njll. , bese uwahlunga ngokohlobo nangombala, bese uwahlukanisa Wahlehle ube yizinhlayiya ezilingana namatshe amatshe.Kulesi sinyathelo, ukucutshungulwa kokuqala kwamapulasitiki kuqedwa ngokuyisisekelo, futhi isinyathelo esilandelayo ukuthi kwenziwa kanjani la mapulasitiki.
Indlela ejwayelekile kakhulu ilula kakhulu, okuwukuncibilikisa ipulasitiki ekushiseni okuphezulu bese uyibumba kabusha ibe eminye imikhiqizo.Izinzuzo zale ndlela zilula, isivinini, kanye nezindleko eziphansi.Inkinga kuphela ukuthi ipulasitiki idinga ukuhlukaniswa ngokucophelela futhi yenziwe kabusha ngale ndlela.Ukusebenza kwepulasitiki kuzokwehla kakhulu.Kodwa-ke, le ndlela ifanele amapulasitiki avamile, njengamabhodlela ethu esiphuzo sansuku zonke namanye amabhodlela epulasitiki, avuselelwa kabusha futhi asetshenziswe kabusha ngale ndlela.
Ngakho ingabe ikhona indlela yokuvuselela engeke ithinte ukusebenza?Yiqiniso kukhona, okungukuthi, amapulasitiki ahlukaniswa abe amayunithi awo amakhemikhali okuqala, njengama-monomers, ama-hydrocarbon, njll., bese ahlanganiswa abe amapulasitiki amasha noma amanye amakhemikhali.Le ndlela iluhlaza kakhulu futhi ingaphatha amapulasitiki axutshwe noma angcolile, yandise ububanzi bokusetshenziswa kwamapulasitiki, futhi yandise inani elingeziwe lamapulasitiki.Isibonelo, imicu yepulasitiki ikhiqizwa ngale ndlela.Nokho, ukugaywa kabusha kwamakhemikhali kudinga ukusetshenziswa kwamandla okuphezulu kanye nokutshalwa kwezimali okukhulu, okusho ukuthi kuyabiza.
Eqinisweni, ngaphezu kokugaywa kabusha nokukhiqiza kabusha amapulasitiki, kukhona futhi ukushiswa okuqondile kwamapulasitiki esikhundleni sikaphethiloli, bese kusetshenziswa ukushisa okukhiqizwa ukushiswa kokukhiqiza amandla noma ezinye izinhlelo zokusebenza.Le ndlela yokugaywa kabusha ayibizi nhlobo, kodwa inkinga iwukuthi izokhiqiza amagesi ayingozi futhi ingcolise imvelo.Le ndlela yokubuyisela kabusha ngeke icatshangelwe ngaphandle uma kudingekile ngempela.Amapulasitiki kuphela angakwazi ukugaywa kabusha ngomshini noma ngamakhemikhali noma angenaso isidingo semakethe azosetshenziswa ngale ndlela.ukubhekana.
Okubaluleke nakakhulu ipulasitiki ekhethekile enokonakala.Le pulasitiki ayidingi ukwelashwa okukhethekile ngemva kokugaywa kabusha.Ingacekelwa phansi ngokuqondile ngama-microorganisms futhi ngeke ibangele ukungcoliswa kwemvelo.Kwa-Jiangsu Yuesheng Technology Co., Ltd., sisebenzise iminyaka eminingi yesipiliyoni ocwaningweni nasekuthuthukisweni kwemishini ukuze sihole ekuthuthukiseni imikhiqizo ecwilisa amagwebu ye-PLA.Sihlinzeka amakhasimende ngamasevisi okuma okukodwa ngokusekelwe ezidingweni zawo ezihlukene futhi akudingeki enze izinguquko kumishini yawo ekhona.Uma wenza noma yiziphi izinguquko, ungakwazi ukuzivumelanisa ngokuqondile!
Kukhona nezinye izixazululo ezihlukile ezizama ukusebenzisa ipulasitiki egaywe kabusha ukudala amanye amakhemikhali.Isibonelo, i-carbon black, esetshenziselwa ukwenza irabha, uyinki, upende neminye imikhiqizo, iguqulwa ibe yi-carbon black kanye namanye amagesi ngokuqhekeka kwemfucumfucu yepulasitiki.Phela, empeleni, le mikhiqizo, njengamapulasitiki, ingathola izinto zokusetshenziswa ngokusebenzisa imboni ye-petrochemical, ngakho-ke akunzima ukuqonda ukusebenzisana kwabo.
Okumangaza nakakhulu ukuthi ipulasitiki egaywe kabusha ingasetshenziswa ukwenza i-methanol.Udoti wepulasitiki uguqulwa ube yi-methanol namanye amagesi ngokufakwa kwegesi nokuguqulwa kwe-catalytic.Le ndlela inganciphisa ukusetshenziswa kwegesi yemvelo futhi yandise ukukhiqizwa nokusebenza kahle kwe-methanol.Ngemva kokuthola i-methanol, singasebenzisa i-methanol ukwenza i-formaldehyde, i-ethanol, i-propylene nezinye izinto.
Kunjalo, indlela ethile yokugaywa kabusha esetshenziswayo incike ohlotsheni lwepulasitiki, njengepulasitiki ye-PET, okuyi-thermoplastic esobala evame ukusetshenziselwa ukwenza amabhodlela eziphuzo, izitsha zokudla, njll. Ingaphinda igaywe kabusha ngemishini ibe yimikhiqizo ye-PET nezinye izimo nemisebenzi. .Le nqubo ingasetshenziswa kulayini wokukhiqiza we-PET we-Jiangsu Yuesheng Technology Co., Ltd., ebambe iqhaza kakhulu ocwaningweni nasekuthuthukisweni kwama-extruder epulasitiki kanye nemishini ehlobene.Ngokukhiqizwa kwamabhizinisi, singahlinzeka ngezixazululo eziphelele zokucutshungulwa kwe-polymer material extrusion.Iyunithi ye-extrusion granulation enamalungelo empahla yobuhlakani ezimele iyaqhubeka nokwenza inqubekelaphambili futhi ilethe amakhasimende imikhiqizo yekhwalithi ephezulu kanye nolwazi olungcono kakhulu lomsebenzisi.
Ukugaywa kabusha kwepulasitiki kusiza ukunciphisa ukuncika kuwoyela ongahluziwe, konga izinsiza, ukuvikela imvelo nempilo yabantu, futhi kunciphise ukukhishwa kwesisi esibamba ukushisa kanye nokulimala kokungcoliswa kwepulasitiki.Amapulasitiki angcolile esiwalahlayo ekuphileni kwethu kwansuku zonke, uma engasetshenziswa kabusha ngokugaywa kabusha, ngolunye usuku azobuyela emphakathini wesintu ngezinye izindlela.Ngakho-ke, kithina, into ebaluleke kakhulu ukuhlukanisa kahle udoti futhi uvumele ukuthi usetshenziswe kabusha.Abahambayo, labo okufanele bahlale.Ngakho-ke uyazi ukuthi yini okufanele uyisebenzise kabusha imikhiqizo yepulasitiki?
