I-Crystal Drystal Dryser ye-R-PET pelletizing / umugqa wokukhishwa
Ukuwongwa kwangaphambili kwe-infrared of pet flakes: Ukuphuma okwandayo kanye nokwenza ngcono ikhwalithi exkeleni lezilwane ezifuywayo
>> Ukuphindisela ama-flakes ku-extruder kunciphisa i-IV ngenxa ye-hydrolysis yikhona ukuba khona kwamanzi,Futhi yingakho ukumiswa kwangaphambili kufinyelela ezingeni lokumisa nge-homogeneous ngohlelo lwethu lwe-IRD kungakhawulela lokhu kuncishiswa. Ngezengezo, i-resin ayiphuzi ngoba isikhathi sokusoma siyancishiswa (Isikhathi sokumisa sidinga kuphela ama-15-20mins, umswakama wokugcina ungaba≤ 50ppm, ukusetshenziswa kwamandla okungaphansi kwama-80W / kg / h), futhi ukuchezula ku-extruder ngakho-ke kuyancipha ngoba impahla eseshayekile ingena kwi-extruder ekushiseni okungapheli "
>> Esinyathelweni sokuqala, i-pet regred iklelisiwe futhi yomiswe ngaphakathi kwe-IRD kungakapheli isikhathi semizuzu eyi-15. Le nqubo ye-crystallization nenqubo yokomisa itholakala ngenqubo eqondile yokushisa isebenzisa imisebe ye-infrared, ukufezekisa izinga lokushisa le-170˚C. Ngokungafani nezinhlelo ezishisayo ezishisayo, okufakwayo kwamandla okusheshayo futhi okuqondile kusiza ukuguquguquka okuphelele kwamanani aguquguqukayo aguquguqukayo aguquguqukayo - Uhlelo lokulawula lwemisebe ye-IR luvumela ukuphendula izimo zenqubo eziguquliwe ngemizuzwana. Ngale ndlela, amanani asukela phakathi kuka-5,000 no-8,000 PPM ancishiswe homogeneight ngaphakathi kwe-IRD kwizinga elinomswakama osalayo acishe abe ngu-30-50ppm.
>>Njengomphumela wesibili wenqubo ye-crystallization ku-IRD, ubuningi obuningi bomhlaba buyenyuka,ikakhulukazi emafulethini anesisindo esincane. Lo mphumela wesibili uthakazelisa kakhulu ngokulwa nesizinda lapho ukuthambekela emabhodleleni amancane abiyelwe kuvimbela izinto zokuvuselela kabusha ekuzuzeni izinqwaba ze-0.3 kg / DM³. Ukwanda kobuningi obuningi ngo-10 kuye kwangama-20% kungatholakala ku-IRD, okubonakala kungasho lutho lapho kubona kuqala, kepha kuthuthukisa ukusebenza kokuphakelayo endaweni yokungena ngaphakathi - kanti ijubane le-extruder lihlala lingashintshiwe, kunokusebenza okuthuthukisiwe kakhulu esikulumweni.
