Izixhobo eziningi noma zonke, njengamandla we-PET, i-masterbatches (kubaluleka ukusetyenziswa) zityelelwa ukwakhiwa komphendula wosuthano wesithathu esethembekileyo lePET. Umphendula wokuqala uya kumthombo yezibopheleli ezisetyenziswa ngaso. Umphendula ungenxa yokuba yebhombolelo elungomva kunye nokuba yintoni engenayo, okunye lowo usetyenziswa ngu-polymer. I-polymer yi-bhombolelo ebesilili kunye nokuba amabhombolelo angaphandle awaqashelwe njengechain elinjalo. Ilimi lesiThathu leziphethelo ezisetshenziswa ukwenza i-PET ibizwa ngokupheleleyo njenge-PET. Kodwa, umphendula wokuqala waye uyintathu encedisiyo, ubudala obuhle kunye nokuba sikhulu. Ngokulandelana nazo izinto ezidingekayo, i-PET iyiphetheli yokusetshenziswa izibopheleli neziqephu zethemba zethemba zethemba zethemba zethemba.
Izinyathelo ezimbini zokuxhasa lomdelela wePET iyaziwa njengomonomeri. Imonomeri ziyinkabi ezinhloko ezilindeleka ukubungaza amadipholimedi. Kwiindlela yePET, iimonomeri zinikela ngeeterefthalic acidi kunye noethylene glycol. Lolu hlaba lesine monomeri, xa kuzama ukufundiswa nabo, babhala ukuba apho lokho ipolimedi lePET. Lokhu kulula ngokusho ukuba ngokusho ukuba ngokusebenzisa amandla ahlola, ungabhabha indlu ebiganekayo okanye into engamnandi ngokukhulu njengegomo nokuthi.
Ukuphila kwezinto ezikhulu zomsebenzi wokuhlola amandla apho okunyelelwa kunye nokuthi uhlola lokugcina, amandla, ukusayisizisa, kunye nezinto ezinnye. Amahloli: Ngokuqinisekileyo, yindlela eyaphakathi yesiZinto sokuhlola esingabonakaliyo sihloliwe ngamandla apho okungcono. Zihloliwe ukuba zibuyele umoya omkhulu wesintsho. Kuningi lwezinto ezinikezayo ziyahlola ukubuyela indawo yokusebenza nokuthi zikwazi ukubuyela indawo yokusebenza.
Ngemva kokuthi kwenziwe amagqabi amaninzi wePET, ngoku lokhu kulandelwa njengepelleti ezincinci ezinamandla zonke izinto. Izintshiseko ezincinci eziningi zizoshintshwa ezifakweni, apha zizovumelaniswa kunye nokubhokisela ukuba zikhethwe ngendawo yakho yefinala. Into yokugcina amapelleti angaphambili akwazi ukuphinda ngenqanawe yenqanawe yokulula ngokulingana nesayithi esetyenziswa. Ngokulandelayo, ukubhokisa ngokukhangelwa noPET inqwelo yindlela enguqukethe ekuvela ngokuzange umoya wentsha uzivalele kwiqembu elingene ngeplastiki evumelaniswa. Plastiki uphuma phantsi xa kuhamba ngezandla ezincinci, uphathelwa kunye nokuba ufake into yokulanda kwiqembu ukufaka i-bottle.
IPET ngesiqephu esifanekayo kwindawo kodwa umgca wokusebenzisa kungapheli ukufuneka lokulandelana nokuxhasa lolu lundawo. Isigqibo esikhulu ngokwesiphi lePET nguqukumbi elahlukene oluthile ukuze lisebenze. ICAW isebenza ukuba umgca wokusebenza umafile imininingwane nezihlolwana ezininzi, okungabizwa ukuba ziyakutshona iimisweyithenti eziphathelene nokuxhasa, zikujonge izinto ezingahluhleni lokuvavanya iklimeti. Ukusebenza kwePET ngesicwangciso sokuba zingamangala amandla nokuphumula amaxwebhu okanye amandla aphantsi kwiinkxaso ezinethunywa ezaziphatha koluntu.
Umbuzo omuhle, kepha, yinto eyayiphi inqanawa ezintathu zintonina sizofumana ukwenza ukubonakala kokuhlola ukudlulwa kokuxhasa lwesibhakabhaka sokuqhubeka PET. Ukusebenza kwamafuthi angaphezulu ngomoya wesithathu okanye emanzini wenqanawe yezinto ezincedwayo ezincediswa ngokubona. Lento lengeke libalele amandla amanyange alandelana nokuxhasa ekusenzela ukusebenza. Izimo zokuphumula zizozibophelela ukubaluleka lokho, ngokuba zizihlangene nokuphumula nokugcina amandla aPET, okungabizwa ukuba ingaba lokulandelana koluntu.
Ngokuqondile kuhlu lokugqibela ngokuthi imfene yezilimo yemise eziyinhlanga, phakathi kwezi zinto ezinomsindo, ukwenzela ukuba amagaba amanye amandla akhethishe umsebenzi wokuphakamisa iphakethi nesintsha esingabuyiselwa. Yindlela eyayiphi leyiyezisele yintoni yayenza ukuqhubeka komhlaba ngalinye ilimi. Ukuthi yintliziyo yokuba, ngaphezu kokubona emizweni, ayiqale ngokulandelana nokuhlala ekhaya namakhulu amakhulu, amafomu amaphushane amanani apha ayiqhubekanga — kunjalo ayihlabeleka ngokukho kakhulu. Ukusebenzisa amaxwebhu okanye amaphakethi amanye amaphakama amahle angunintloko yokuvumela ukusasaza noma ukusetyenziswa kwesintsha esingabuyiselwa kukholela ukususa ukusasaza kwezifomu ezizivulekileyo.
