Cov Ntawv Yas Extruders yog cov khoom tseem ceeb hauv cov plastics ua kev lag luam, siv tau dav hauv cov ntaub ntawv hauv tsev, cov ntawv thov kho mob, thiab lwm thaj teb. Tom qab xyoo ntawm cov kev paub tswv yim, Kuv tau qhia txog qee cov kev paub tseem ceeb rau kev siv los ntawm cov kws tshaj lij kev lag luam.
Cov Khoom Siv Khoom Siv thiab Chaw Haujlwm
Thaum xaiv tus Extruder, lub hau ntsag cov taub, nam piv (L / D), thiab hom cua sov, thiab khoom siv, tus tsiaj, thiab lwm yam). Thaum lub sij hawm ua haujlwm theem, kev tswj qhov kub yog qhov tseem ceeb heev. Cov yaj ntawm cov khoom sib txawv txawv. Piv txwv li, PP feem ntau yuav tsum tau 180-220 degree, thaum tsiaj yuav tsum tau 240-280 degree. Nws raug nquahu kom nce qhov ntsuas kub nyob rau theem kom tsis txhob muaj cua sov sai uas yuav ua rau cov lus tsis txaus siab. Tsis tas li ntawd, qhov txuam ntawm ntsia hlau ceev thiab rub tawm ncaj qha cuam tshuam rau kev sib txawv ntawm daim ntawv tuab thiab yuav tsum tau hloov kho los ntawm ntau cov pwm kev sim siab.
Cov khoom siv raw ua ntej thiab cov txheej txheem ua kom zoo
Raw khoom qhuav yog qhov tseem ceeb heev. Hygroscopic cov ntaub ntawv (xws li tus tsiaj thiab PA) yuav tsum tau qhuav ntawm 80 {{}}} 120℃rau 4-6 teev; Txwv tsis pub, noo noo yuav ua rau cov npuas lossis cov pob nyiaj. Thaum sib xyaw ua ke ntxiv (xws li masterbatches thiab cov tshuaj tua neeg sawv cev), nws raug nquahu kom siv lub tshuab ceev ceev kom ntseeg tau tias muaj kev sib cais ua ke. Thaum lub sijhawm tsim khoom, kev xaiv ntawm lub lim (feem ntau 100-300 mesh muaj peev xwm txhim kho daim ntawv huv si, tab sis nws yuav tsum tau hloov tsis tu ncua kom tsis txhob hloov siab hloov pauv.
Cov teeb meem thiab kev daws teeb meem
Cov ntawv tsis xws luag xws li tsis sib xws, laim ntoom npoo, thiab sab saum toj. Thickness sib txawv feem ntau vim yog tsis muaj kev sib tuag Lip Gap kho tau, uas tuaj yeem raug kho tau siv nplua}} tuning screws. Cov npoo laim ntauv yog feem ntau tshwm sim los ntawm kev txias txias; Khij qhov ntsuas kub tau ntawm peb - roll calender (60-80℃rau lub slot yob, qis dua rau nruab nrab thiab qis dua). Qhov pitting nplaim yuav yog vim yog cov khoom siv raw lossis cov carbon tso rau ntawm lub taub hau tuag; Cov no yuav tsum tau nres thiab ntxuav.
Kev Txij Nkawm thiab Kev Nyab Xeeb
Thaum niaj hnub saib xyuas, tsom mus rau kev tshuaj xyuas cov ntsia hlau thiab lub thoob rau hnav thiab ntub lub ntub lub zog tsav. Txog kev nyab xeeb ua haujlwm, yuav ceev faj tawm tsam kub hnyiab ntawm cov khoom siv kub thiab hluav taws xob tsis ua haujlwm. Nruab ib qho khoom siv thaum muaj xwm ceev thiab tsheb ciav hlau ua haujlwm ntawm kev ua haujlwm kom zoo.
Kev paub qhia tau tias qhov chaw ruaj khov los ntawm ceev faj kom meej. Kev ua haujlwm txuas ntxiv ua haujlwm thiab tiv thaiv kev tiv thaiv tuaj yeem txuas ntxiv txuas ntxiv cov khoom lub neej thiab cov khoom lag luam zoo.
