Infrared crystal tshuab ziab khaub ncaws rau r-tsiaj pelletizing / extrusion kab
Cov nplaim taws infrared ua ntej qhuav: nce tawm zuj zus thiab txhim kho cov khoom zoo ntawm cov tsiaj extruders
>> reprocessing cov flakes nyob rau hauv extruder txo qis iv vim muaj hydrolysis Kuv muaj cov dej,Thiab yog vim li cas pre-ziab rau homogeneous qhuav qib nrog peb lub tshuab IRD tuaj yeem txwv qhov kev txo qis no. Hauv kev ntxiv, lub resin tsis daj vim tias lub sijhawm ziab yog txo (Lub sijhawm kom qhuav tsuas yog xav tau 15-20mins, noo noo tuaj yeem yog≤ 50FPM, Kev Siv Zog Tsawg dua 80W / KG / h), thiab shearing hauv Extruder yog li kuj tau txo vim tias cov khoom siv preheated nkag mus rau tus extruder ntawm qhov kub tsis tu ncua "
>> nyob rau hauv thawj kauj ruam, tus tsiaj regind yog crystallized thiab qhuav hauv iRD tsis pub dhau 15 feeb. Qhov txheej txheem crystallization thiab cov txheej txheem kom qhuav yog ua tiav los ntawm kev siv hluav taws xob kub ceev, kom ua tiav cov khoom kub ntawm 170˚c. Nyob rau hauv sib piv rau lub tshuab hluav taws kub qeeb, cov tswv yim ceev thiab ncaj qha hloov pauv cov tswv yim noo noo pub teb rau cov txheej txheem hloov kho hauv vib nas this. Nyob rau hauv txoj kev no, qhov tseem ceeb nyob nruab nrab ntawm 5,000 ppm yog txo homogeneously nyob rau hauv IRD rau kev ua haujlwm noo noo ntawm txog 30-50ppm.
>>Raws li kev cuam tshuam theem nrab ntawm cov txheej txheem crystallization hauv IRD, qhov ntom ntom ntawm cov khoom hauv av nce,Tshwj xeeb tshaj yog nyob rau hauv lub teeb liab-hnyav flakes. Cov nyhuv theem nrab no yog qhov nthuav dav heev uas yog nyiam ntawm nyias cov khoom siv rov qab los ntawm kev ua tiav cov qauv siv ntawm> 0.3 kg / dm³. Qhov nce ntawm cov tuab ntom ntom los ntawm 10 txog 20% tuaj yeem ua tiav hauv qhov tsis muaj qhov tsis txaus ntseeg ntawm kev ua tiav, tab sis txhim kho cov khoom noj khoom haus hauv thawj zaug, tab sis muaj kev hloov pauv ntau yam tsis hloov pauv ntawm cov ntsia hlau.
