Infrared crystal dryer yeR-PET Pelletizing/ Extrusion Line
Infrared Pre-Drying yePET Flakes: Kuwedzera Kubuda uye Kuvandudza Hunhu paPET Extruders.
>> Kudzoreredza maflakes mune extruder kunoderedza IV nekuda kwehydrolysis i kuvapo kwemvura,ndosaka kufanoomesa kusvika kune homogeneous yekuomesa nhanho neIRD System yedu inogona kudzikamisa kudzikiswa uku.Mukuwedzera, iyo resin haina yero nekuti nguva yekuomesa yakaderedzwa (Nguva yekuomesa inongoda 15-20mins, hunyoro hwekupedzisira hunogona kuva≤ 50ppm, kushandiswa kwesimba kuri pasi pe80W/KG/H), uye kuveura muextruder kunoderedzwawo nekuti iyo preheated material inopinda muextruder patembiricha isingaperi”
>> Mune danho rekutanga, iyo PET regrind yakakwenenzverwa uye yakaomeswa mukati meIRD mukati menguva ingangoita maminetsi gumi nemashanu.Iyi crystallization uye kuomesa maitiro anowanikwa neakananga kupisa-up maitiro uchishandisa Infrared radiation, kuwana tembiricha yezvinhu ye170˚C.Mukupesana neanononoka-anopisa-mhepo masisitimu, iyo inokurumidza uye yakananga simba yekuisa inofambisa yakakwana egalisation yekusingaperi inochinja-chinja yekuisa mwando kukosha - iyo control system yeIR radiations inobvumira kupindura kune yakashandurwa maitiro mamiriro mukati memasekondi.Nenzira iyi, hunhu hunobva pakati pe5,000 ne8,000 ppm hunodzikiswa zvakafanana mukati meIRD kusvika kune yasara mwando mwero we30-50ppm.
>>Seyechipiri mhedzisiro yeiyo crystallization process muIRD, kuwanda kwakawanda kwezvinhu zvepasi kunowedzera,kunyanya mumaflakisi akareruka.Iyi yechipiri mhedzisiro inonakidza kwazvo kuseri kwemashure kuti tsika yekuenda kumabhodhoro akatetepa-akadzivirirwa inodzivirira iyo inodzokorodza zvinhu kubva mukuzadzikiswa kwehuwandu hwe> 0.3 kg/dm³.Kuwedzera kwehuwandu hwehuwandu ne10 kusvika 20% kunogona kuwanikwa muIRD, iyo inoita seisina kukosha pakutanga kuona, asi inovandudza kushanda kwekudya pane extruder inlet zvakanyanya - nepo extruder speed inoramba isina kuchinja, pane yakagadziridzwa zvakanyanya. kuzadza kuita pane sikuruu.
