Dab tsi yog cov khoom siv raw rau extrusion molding?

Cov khoom siv hlau
Hlau yog ib qho ntawm feem ntau siv raw cov ntaub ntawv hauv extrusion molding. Cov khoom siv hlau extrusion feem ntau suav nrog txhuas, tooj liab, magnesium, zinc, hlau, thiab lwm yam. Cov hlau no muaj cov yas zoo thiab ductility, thiab tuaj yeem ua rau cov yas deformation ntawm qhov kub thiab txias, yog li raug extruded rau hauv ntau yam khoom zoo li tus.
Aluminium: Txhuas thiab nws cov alloys yog ib qho ntawm cov khoom siv hlau feem ntau siv hauv extrusion molding. Lawv muaj qhov tsis tshua muaj zog, muaj lub zog tsis zoo, zoo corrosity tsis kam, thiab rov ua dua tshiab siv hauv cov liaj teb xws li aerospace, kev tsim kho tsheb, thiab kho kom zoo nkauj. Aluminium profiles tsim los ntawm extrusion muaj qhov zoo xws li qhov chaw du, qhov loj me, thiab kev ua haujlwm ruaj khov.
Tooj liab: tooj liab thiab nws cov alloys kuj yog siv rau hauv extrusion molding, tshwj xeeb tshaj yog nyob rau hauv hluav taws xob thiab hluav taws xob industries. Copper lub siab conductivity, zoo thermal conductivity, thiab corrosion kuj ua rau nws yog ib qho zoo tagnrho cov khoom rau cov khoom xws li cov xov hlau, cables, connectors, thiab cua sov dab dej. Extrusion molding tuaj yeem xyuas kom meej qhov loj me thiab qhov zoo ntawm cov khoom siv tooj liab, ua tau raws li qhov yuav tsum tau ua ntawm precision manufacturing.
Magnesium: Magnesium alloy yog cov khoom siv hlau hnyav uas tau tshwm sim nyob rau xyoo tas los no, nrog lub zog tshwj xeeb thiab nruj, ua rau nws tsim nyog rau thaj chaw uas yuav tsum tau txo qhov hnyav, xws li aerospace thiab automotive manufacturing. Extrusion molding yog ib txoj hauv kev tseem ceeb rau kev ua cov magnesium alloys, uas tuaj yeem tsim cov khoom sib xws thiab kev ua haujlwm siab.
Cov khoom siv yas
Yas yog lwm yam khoom siv tseem ceeb hauv extrusion molding. Yas extrusion molding feem ntau koom nrog extruding molten yas los ntawm pwm los tsim cov khoom ntev ntev xws li cov kav dej, profiles, zaj duab xis, thiab lwm yam.
Polyethylene (PE): Polyethylene yog ib qho ntawm cov khoom siv yas extrusion ntau tshaj plaws, nrog rau cov tshuaj zoo heev, tsis kub tsis kam, thiab kev ua haujlwm zoo. PE extruded khoom yog dav siv hauv ntim, kev tsim kho, kev ua liaj ua teb thiab lwm yam kev lag luam.
Polyvinyl chloride (PVC): PVC plays lub luag haujlwm tseem ceeb hauv extrusion molding vim nws lub cev zoo heev thiab kev tiv thaiv corrosion. PVC kav, hlau rwb thaiv tsev txheej, cov ntaub ntawv hauv pem teb, thiab lwm yam yog cov neeg sawv cev ntawm PVC extruded khoom.
Polypropylene (PP): Polypropylene muaj cov cua kub zoo heev, tshuaj tiv thaiv, thiab lub zog txhua yam, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim khoom xws li ntim khoom noj, khoom siv kho mob, thiab cov khoom siv tsheb. Extrusion molding tshuab tuaj yeem tsim cov khoom zoo PP.
Ceramic raw khoom
Txawm hais tias cov ntaub ntawv ceramic muaj siab hardness thiab brittleness, lawv tuaj yeem ua tiav rau hauv ntau yam khoom siv los ntawm kev siv tshuab extrusion siab heev. Ceramic extrusion molding feem ntau yog siv cov hmoov metallurgy txoj kev, uas sib tov cov hmoov ceramic nrog cov ntawv khi thiab extrudes nws mus rau hauv cov duab, thiab tom qab ntawd ua tiav cov txheej txheem tom ntej xws li sintering kom tau txais cov khoom kawg.
Aluminium oxide (Al ₂ O3): Aluminium oxide ceramics yog siv dav hauv kev siv tshuab, hluav taws xob, tshuaj lom neeg thiab lwm yam kev lag luam vim lawv cov hardness siab, siab hnav tsis kam thiab tshuaj lom neeg zoo heev. Extrusion molding thev naus laus zis tuaj yeem tsim cov khoom siv high-precision, complex zoo li alumina ceramic Cheebtsam.
Silicon nitride (Si ∝ N ₄): Silicon nitride ceramics muaj hardness siab heev, zoo thermal stability, thiab corrosion kuj, ua rau lawv yog ib qho zoo tagnrho cov ntaub ntawv rau high-temperature ib puag ncig. Los ntawm extrusion molding tshuab, silicon nitride ceramic khoom nrog cov duab nyuaj thiab cov khoom zoo heev tuaj yeem npaj tau.
