Indlela iibhotile zePET ezenziwa ngayo

Iibhotile zePETziikhonteyina zeplastiki ezenziwe ngezinto zeplastiki zePET ngokusebenzisa inkqubo yenyathelo elinye okanye ezimbini. Iibhotile zePETibonakaliswa bubunzima bayo obulula, ukukhanya okuphezulu, kunye nokumelana nokuchasana nokuqhekeka.

i-PET ye licebiso bi-ottle, okanye i-polyethylene terephthalate, idla ngokubizwa ngokuba yi-polyester. Igama layo lesiNgesi yiPolyethylene Terephthalate, eveliswa yi-polymerization reaction (condensation) yezinto ezimbini zekhemikhali: i-terephthalic acid (PTA) kunye ne-ethylene glycol (EG).

Iifomu zangaphambili ze Iibhotile zePETzizinto ezibunjwe ngenaliti. Njengeemveliso eziphakathi ezigqityiweyo zokubumba i-biaxial stretch blow molding, intamo ye-preform sele yenziwe ngexesha lesigaba sokubumba inaliti, kwaye ubungakanani bayo abuyi kutshintsha ngexesha lokufudumeza kunye nokusolula/ukuvuthela. Ubungakanani, ubunzima, kunye nobukhulu bodonga lwe-preform zizinto ekufuneka siziqwalasele xa sivuthela. Iibhotile zePET.

Ububanzi be licebiso bi-ottle Umlomo onokudlula uquka i-Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, njl. (ehambelana nobukhulu be-T bomlomo webhotile), kwaye iinkcukacha zentambo yesikrufu zihlala zahlulwe ngolu hlobo: 400, 410, 415 (ehambelana nenani leentambo zesikrufu ezijikajikayo). Ngokubanzi, sithi i-400 yijika eli-1 lentambo yesikrufu, i-410 yijika eli-1.5 lentambo yesikrufu, kwaye i-415 yindawo ephezulu eneejika ezi-2 zentambo yesikrufu.

Njani Iibhotile zePETzenziwe:

Inkqubo egqibezela iinkqubo zokujova, ukolula kunye nokuvuthela kumatshini omnye ibizwa ngokuba yindlela yenyathelo elinye. Kwindlela yenyathelo elinye, emva kokuba i-preform ijova ibunjiwe kwaye ipholiswe, ukolula kunye nokuvuthela licebiso bi-ottle isenzo siyaphunyezwa. Iingenelo zayo eziphambili kukonga amandla, ukuvelisa okuphezulu, akukho kungenelela ngesandla, kunye nokunciphisa ungcoliseko.

Indlela enamanyathelo amabini yahlula ukujova, ukolula kunye nokuvuthelalicebiso bi-ottle, kwaye izenze kwiimashini ezimbini ngamaxesha ahlukeneyo, ezaziwa ngokuba yi-injection-stretch-blowing licebiso bi-ottle inkqubo. Kwinyathelo lokuqala, i-preform ibunjwa ngenaliti kusetyenziswa umatshini wokubumba ngenaliti. Kwinyathelo lesibini, i-preform kubushushu begumbi iyafudunyezwa kwaye yolulwe ize ivuthelwe ngaphakathi Iibhotile zePETIingenelo zendlela enamanyathelo amabini kukuba inokuthenga iipreforms zokufaka i-blow molding. Inganciphisa utyalo-mali (kubasebenzi nakwizixhobo). Umthamo wepreform umncinci kakhulu kunowebhotile, nto leyo eyenza kube lula ukuyithutha nokuyigcina. Iipreforms eziveliswa ngexesha lokungasebenzi zingavuthelwa kwi-blow molding. Iibhotile zePETkwixesha leencopho.

Iibhotile zePETzisetyenziswa kakhulu kushishino lwezithambiso, ikakhulu kwicandelo lokhathalelo lweenwele kunye nokhathalelo lomzimba. Iibhotile zeshampu, ukuhlamba umzimba, i-toner, kunye neoyile yokususa izimonyo zonke zenziwe nge-blow molding.
