Qhauv Kev Pab Txog Plastic Extrusion rau Polyamide Thermal Break Strips

Kev tsim kho tshuab plastic yog kev tsim kho tshuab siv ntau thiab muaj nuj nqi sib npaug uas pib los ntawm cov khoom siv thermoplastic raw mus rau cov khoom siv uas muaj dunder ib txoj hlua sib npaug. Nws yog ib qhov chaw siv tshuab zoo tshaj plaws thiab siv ntau tshaj plaws hauv cheeb tsam khoom siv plastic, uas tshwm sim ntau yam khoom siv xws li huab cua, xim, films, thiab cov dunder tseem ceeb xws li cov siv rau kev kuaj xyuas kub nyob rau hauv kev tsim kho. Kev tsim kho no pib los ntawm cov resin plastic nyob rau hauv daim phem uas tau muab tso rau hauv barrel ntawm extruder. Hauv barrel no, ib lub screw roj teeb uas muaj kev kho tshuab zoo siab tuaj yeem ua ntau yam txheej xeem: nws xa cov khoom siv taw tes, ntxig nws, thiab los ntawm kev siv roj tshuab nres thiab kev cuam tshuam hauv, thawv nws mus rau ib qhov chaw uas muaj zog. Lub plastic thawv no tom qab ntawd tau raug ntxuav tso rau hauv ib qhov chaw tshwj xeej uas tsim tshiab, uas tsim nws mus rau daim dunder uas xav tau. Thaum tawm los ntawm qhov chaw no, lub extrudate npuaj ntsha thiab npuaj kub yuav tsum tau raug ntxuav kom ncav rau sab nraud thaum twb muaj dunder. Txoj kev no tau muab los ntawm kev siv calibration thiab cooling system, tshwj xeej yog siv vacuum calibration tanks thiab water baths, uas muab tso rau hauv qhov chaw tshwj xeej. Ib qhov haul-off unit tom qab ntawd yuav tso tseg lub profile uas twb ncav lawm nyob rau ib qhov chaw uas muaj kev coob meej uas sib txuas nrog lub extruder. Thaum kawg, lub khoom siv tshuab tseem ceeb no yuav raug muab faus lossis muab ntxoov rau hauv coils. Qhov kev pib zoo ntawm kev tsim kho plastic yog qhov kev coob meej ntawm ntau yam kev txwv, xws li viscosity ntawm khoom siv, kub ntawm thawv, kev nqaj ntawm screw, thiab kev ntxuav kub, kom paub meej tias lub khoom siv tshuab tseem ceeb muaj qhov ntev sib npaug, siv zoo, thiab muaj qhov surface finish zoo.
