Cov Khoom Siv Yas Rov Qab
Raws li cov kev xav tau ntawm cov yas molding ua thev naus laus zis, tsis hais leej twg siv rau kev rov ua dua tshiab. Feem ntau, granulation xav tau. Cov granation cov txheej txheem faib ua ob pawg: cold ventulation thiab granmation kub. Lub ntsiab sib txawv ntawm ob lus dag nyob rau hauv kev npaj ntawm cov txheej txheem granation lub sij hawm. Txias txiav cov kab ke, uas txiav cov nplej los ntawm cov polymer thaum kawg ntawm cov txheej txheem; Nyob rau hauv lub neej tuag saum cov pellet kub pellet, molten polymer raug txiav thaum nws tawm los ntawm txoj kev tuag, thiab cov pellet yog txias ntws los.
Cov kev xaiv tshwj xeeb ntawm txoj kev twg yog nyob ntawm hom yas thiab molding khoom, raws li cov khoom siv sib txawv thiab cov ntaub ntawv yas, kev siv cov khoom siv cov roj hmab sib txawv, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv cov roj hmab sib txawv, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv yas, kev siv cov khoom siv granulator sib txawv.
Nyob rau hauv kev rov ua dua ntawm cov khib nyiab plastics, cov extruders feem ntau yuav tsum tau ua. Cov khib nyiab yog melted thiab yas los ntawm extruder, extruded sawb cov ntaub ntawv, thiab txiav mus rau hauv pellets ncaj qha lossis tom qab txias raws li cov lus qhia uas yuav tsum tau ua. Cov khoom siv rov ua cov khoom siv tau siv los ua cov ntaub ntawv raw rau kev ua cov khoom siv ntau yam hauv lub neej.
Sab xub ntiag ntawm lub qub yas dua extruder muaj cov khoom siv lim dej uas tseem ceeb tshaj plaws hauv kev rho tawm cov kev tshem tawm thiab moulding ua ntawm cov khib nyiab plastics. Nws yog siv los tshem tawm cov khoom tsis txaus nyob hauv cov khib nyiab, xws li xuab zeb, fiber ntau thiab lwm yam kom muaj qhov zoo ntawm cov khoom lag luam thiab cov txheej txheem extrusion du. Cov ntaub ntawv pov tseg khib nyiab ntau zaus tau ua paug rau qib sib txawv, txawm tias tom qab tu, thiab lwm yam, yog li cov lim dej yuav tsum tau hloov ntau thaum nws ua. Thaum hloov lub taub lim, koj yuav tsum nres lub tshuab ua ntej, disassemble lub taub hau extruder thiab hloov lub taub lim dej thaum cov khoom txias tsis tiav. Cov txheej txheem no yuav ua rau muaj kev ua tau zoo ntawm cov extruder los txo cov ntawv pov tseg, kev ua ntawm cov khib nyiab uas tsis muaj tseeb, yog li nws yog qhov tsim nyog los siv lub lim tshuab hloov.
Rau cov yas nyias muaj nyias, pp, ABS, PVC, PA, thiab lwm yam khoom siv hluav taws xob tshwj xeeb, cov txheej txheem txiav khoom siv tau yog huab cua txias tuag saum npoo kub. Polystyrene, txawm hais tias lub duav lossis GPPs, feem ntau cov tuam ntxhab siv inclined dej-txias txiav.
Cov neeg yuav khoom tuaj yeem muab cov ntaub ntawv sib xyaw thiab cov kev daws teeb meem rau cov khoom sib txawv thiab cov khoom siv pelletizing, tos koj kev sib cuag.
