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 ye170˚C. Mukupesana neanononoka kupisa-mhepo masisitimu, iyo inokurumidza uye yakananga simba yekuisa inofambisa yakakwana egalisation yekusingaperi inochinja-chinja yekuisa unyoro hutsika - 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.
