Ukuthenga iibhotile zeplastiki zePET zokuhombisa
Enye yezinto eziphambili ezichaphazela ixabiso lebhotile yeplastiki yePET yindleko yezinto ezisetyenzisiweyo. I-PET (i-polyethylene terephthalate) yeyona nto iphambili esetyenziselwa ukwenza ezi bhotile. Yipolymer eyenziweyo edla ngokuveliswa kwi-terephthalic acid kunye ne-ethylene glycol. Ixabiso le-PET lichaphazeleka kukuguquguquka kweemarike zeoyile eluhlaza kunye ne-petrochemical, njengoko utshintsho kumaxabiso ezinto ezisetyenzisiweyo luchaphazela ngokuthe ngqo iindleko zemveliso ye-PET.
Nje ukuba i-resin ye-PET ifunyenwe, kufuneka icutshungulwe ibe yimo yebhotile ngeenkqubo zokwenza ezifana nokubumba okanye ukubumba ngenaliti. Ezi nkqubo zokwenza ziquka amanyathelo amaninzi aquka ukucubungula izinto eziluhlaza, ukwenza isikhunta, ukusebenza kwezixhobo, unyango lobushushu, kunye nolawulo lomgangatho. Iindleko zamandla, iindleko zomsebenzi, kunye neendleko zezixhobo ngexesha lenkqubo yokwenza zonke zinefuthe kwixabiso lokugqibela.
Kuluntu lwanamhlanje, kukho inkxalabo eyandayo malunga nemiba yokusingqongileyo, kwaye imiba yokusingqongileyo nayo kufuneka iqwalaselwe xa kuqingqwa amaxabiso eebhotile zeplastiki zePET. Oku kuquka iindleko zokulahlwa kwenkunkuma, ukuphinda kusetyenziswe, kunye nokuphinda kusetyenziswe. Ezinye iindawo zifuna abavelisi bahlawulele ukulahlwa kwenkunkuma okanye bathathe inxaxheba kwiinkqubo zokurisayikilisha, kwaye ezi ndleko zinokuchaphazela amaxabiso emveliso.
Abathengi kunye neemveliso ezahlukeneyo banokuba neemfuno ezahlukeneyo zoyilo kunye nokwenza ngokwezifiso iibhotile zeplastiki zePET. Abanye abathengi banokufuna iimilo ezikhethekileyo, imibala, okanye uyilo lweelebheli, kwaye ezi mfuno zongezelelweyo ziya kunyusa iindleko zemveliso. Ubunzima boyilo lokupakisha kunye netekhnoloji yokuprinta buchaphazela nexabiso. Ukhuphiswano lwemarike lubalulekile kwixabiso leebhotile zeplastiki zePET. Ukhuphiswano phakathi kwababoneleli luya kuqhuba ukhuphiswano lwamaxabiso, ngoko ke amaxabiso adla ngokuphenjelelwa zizinto ezifana nokubonelela ngemarike kunye nemfuno, impembelelo yophawu, kunye nesabelo semarike.
Iindleko zokuhamba kunye nokusasazwa nazo zizinto ekufuneka ziqwalaselwe xa kusenziwa amaxabiso eebhotile zeplastiki zePET. Ukuthutha, ukugcina, kunye nokusasazwa ukusuka kumenzi ukuya kumsebenzisi wokugqibela konke oku kuzisa iindleko ezongezelelweyo kwaye kuchaphazela ixabiso lokugqibela lemveliso.
