The quality of recycled PET bottle flakes directly affects the profit level, so improving the quality of recycled PET bottle flakes is a crucial part of the PET recycling industry. The key to improving the quality of recycled PET bottle flakes lies in optimizing the process of the PET washing line, especially in handling humidity, PVC content, and characteristic viscosity.
Improving PET Bottle Flake Quality With PET Washing Line
Humidity Management
Unyevu ni mojawapo ya mambo muhimu zaidi yanayoathiri ubora wa flakes za chupa za PET zilizorejeshwa. Unyevu mwingi huathiri utendaji na usindikaji wa bidhaa. Kwa hiyo, unyevu wa chupa za chupa za PET unapaswa kupunguzwa baada ya kuosha.
Kwa kusudi hili, inashauriwa kutumia vifaa vya kukausha na kukausha, kama vile mashine ya kukausha PET flakes, au, ikiwa kuna mahitaji ya juu, bomba la kukausha au kipanga hewa, ili kupunguza unyevu hadi chini ya asilimia 5.
PVC Content Control
Chupa za PET taka zina kiwango cha juu cha PVC, haswa katika muundo wa karatasi ya lebo. Ili kuhakikisha ubora wa chupa za PET zilizosindikwa, PVC lazima iondolewe kabisa kabla ya usindikaji. Hili linaweza kufanikishwa kwa mashine ya kuondoa lebo ya plastiki, ambayo ina kiwango cha uondoaji lebo cha zaidi ya 98%.
Baadaye, mgawanyo wa plastiki wa kuelea wa kuzama unaweza kutenganisha vipande vya PVC vilivyobaki. Kwa kuongeza, kuongeza ya poda ya kusafisha kwenye tank ya kuosha moto inaweza kupunguza zaidi maudhui ya PVC na kuhakikisha uzalishaji wa flakes za ubora wa juu wa PET zilizosindikwa.
Characteristic Viscosity Management
Mnato wa tabia ni moja ya faharisi muhimu za chupa za chupa za PET zilizosindikwa, na mchakato wa kusafisha kupita kiasi utasababisha mabadiliko katika mali ya mwili, haswa kupungua kwa mnato. Ili kuepuka hali hii, ni muhimu kudhibiti kiasi cha soda caustic na wakati wa kuosha wakati wa mchakato wa kuosha ili kuhakikisha kuwa mnato wa tabia ya flakes ya chupa ni imara. Kwa kawaida hupendekezwa kuwa muda wa usindikaji katika tank ya kuosha moto haipaswi kuzidi dakika 45 ili kudumisha utulivu na uthabiti wa bidhaa.
Conclusion
In summary, optimizing the PET washing line process is the key to improving the quality of recycled PET bottle flakes. By reasonably managing humidity, and controlling PVC content and characteristic viscosity, we can produce higher quality recycled PET bottle flakes, improve profit level, and at the same time make a positive contribution to environmental protection.
