Raw Khoom Xaiv thiab Kev Npaj
Cov kav dej yas feem ntau yog tsim los ntawm cov khoom siv xws li PVC, PE, thiab PP. Cov khoom tsim nyog yuav tsum raug xaiv raws li qhov xav tau siv. Thaum xaiv cov khoom siv raw, cov khoom xws li kub tsis kam, corrosion resistance, thiab mechanical zog yuav tsum tau txiav txim siab. Tom qab xaiv cov khoom siv raw, lawv tab tom npaj. Feem ntau, lub tshuab tov khoom yog siv los sib tov cov yas resin thiab cov khoom siv sib xyaw ua ke, ua raws li kev ziab kom paub meej qhov tseeb dryness thiab proportions ntawm raw cov ntaub ntawv.
Extrusion
Extrusion yog thawj txheej txheem hauv kev tsim cov yeeb nkab yas. Thaum lub sij hawm extrusion, qhuav raw cov ntaub ntawv yog muab tso rau hauv ib tug extruder rau plasticization thiab extrusion. Los ntawm compression, kneading, thiab ncab, cov ntaub ntawv raw yog extruded rau hauv cov yeeb nkab yas tsis muaj qhov xav tau tuab thiab kev ntxhib los mos. Qhov no yog tom qab shaping thiab txiav cov kauj ruam tom ntej.
Shaping thiab txiav
Shaping yog ua kom ua tau raws li qhov xav tau. Lub semi-diameter shaping tshuab feem ntau yog siv los ua cov yeeb nkab yas. Kev txiav yog ua los txiav cov yeeb nkab zoo li qhov ntev rau ntim thiab siv. Lub tshuab txiav tuaj yeem ua haujlwm tau los yog manually, nyob ntawm daim ntawv thov.
Txias thiab tshuaj xyuas cov khoom
Thaum lub sij hawm tsim cov yeeb nkab, cov yeeb nkab extruded yuav tsum tau txias kom tsis txhob deformation thiab cov qauv tsis sib xws. Kev tshuaj xyuas cov khoom yog tom qab ntawd ua kom paub tseeb tias nws cov tsos, qhov zoo, thiab lub cev muaj zog raws li cov qauv, tso cai rau kev hloov kho raws sijhawm rau cov txheej txheem tsim khoom.
Ntim thiab Cia
Tom qab ntau lawm, cov kav dej yas tau ntim raws li cov lus qhia thiab cov kev xav tau zoo. Cov no feem ntau yog ntim rau hauv dai hexagonal ntim lossis reel ntim. Tom qab ntim khoom, lawv yuav tsum tau khaws cia kom deb ntawm noo noo thiab ncaj qha tshav ntuj.
