Extrusion txheej txheem

Ntawm chav kawm, txhawm rau tsim cov khoom lag luam thiab lawv cov khoom siv, nws yog ib qho tseem ceeb tsis tsuas yog tsim cov pwm xwb tab sis kuj kho nws. Yog li ntawd, piv txwv yooj yim ntawm cov tshuaj txhuam hniav ua tsis raws cai ncaj qha nrog kev rho tawm cov txheej txheem siv hauv kev lag luam.

Cov ntaub ntawv feem ntau tau txais kev extruder hauv cov kev mob uas cov khoom siv ua yas thiab tuaj yeem thawb mus rau hauv qhov chaw tuag. Feem ntau, ib qho kub siab yog siv hauv Extruder Chamber. Raws li qhov tshwm sim, cov khoom siv tau yooj yim rau yuam kom raug yuam los ntawm molding lub qhov moulding, uas nws txias thaum nws tawm ntawm lub chav thiab yog li khaws nws cov duab. Xws li cov txheej txheem hu ua kub lossis sov so extrusion.

Ib qho kev zam nthuav dav, nyob rau hauv uas nws yog qhov ntxiv kub tom qab extrusion pab tswj cov duab ntawm cov khoom, yog ci. COON COOLTRAS EXTRE tau dav siv nyob rau hauv kev lag luam no, thiab lub khob noom cookie yog cov khoom siv yas heev. Hauv qhov no, cov duab yog khaws cia thaum lub sijhawm ci txheej txheem vim yog cov tshuaj hloov ntawm lub tshuab envectionery. Thaum cov duab ntawm cov cuab yeej siv cov qauv feem ntau yog tswj kom txias, qhov twg ntawm cov ntsiab cai dav dav ntawm kev ua haujlwm hnyav ntawm cov ntaub ntawv nrog qhov ntsuas kub tsawg dua.

Kuj tseem muaj txoj hauv kev ntawm txias extrusion. Hauv qhov no, cov khoom siv muaj zog txaus ntawm cov ntaub ntawv tau tiav los ntawm kev siv tshuab, piv txwv li, los ntawm kev tsim cov siab nce ntxiv hauv cov chav kawm extruder. Cov txheej txheem yuav siv qhov chaw tsis muaj cua sov cov khoom siv. Cov txheej txheem no tuaj yeem siv los tsim cov hlau zoo uas tuaj yeem siv tau ntau yam kev lag luam. Cov hlau, feem ntau yog nyob rau hauv daim ntawv ntawm lub tog raj kheej, yog ntxig rau hauv Extruder Chamber thiab ces cov neeg kho tshuab siv rau nws. Qhov no ua rau cov hlau kom raug thawb los ntawm kev qhib ntawm tuag, sib sau cov khoom lag luam uas xav tau. Cov txheej txheem yog nqa tawm siv presses lossis cov khoom siv me tshwj xeeb uas tsim nyog rau kev siv hluav taws xob tsim nyog.

Txias txias extrusion yog zoo haum rau cov qauv siv siab, xws li txhuas, tooj liab, thiab cov hlau tshwj xeeb, thiab tsis muaj tooj liab tuaj yeem cuam tshuam qhov kev siv ntawm cov txheej txheem no. Lub ntsiab zoo ntawm txias extrusion yog lub siab precision thiab zoo ntawm cov khoom tau thiab tus nqi-ua tau zoo ntawm cov txheej txheem.

Lub siab yuav tsum tau siv rau hlau extrusion tsis yog tsuas yog nyob rau ntawm cov khoom ntawm cov hlau nws tus kheej, tab sis kuj ntawm cov cheeb tsam thiab tuab ntawm cov khoom lag luam los tsim. Raug Pressures rau kev tshem tawm txias ntau yam txij li 200 txog 1500 bar. Txawm li cas los xij, rau cov zis loj dua lossis thinner profiles, ntau dua ntau dua kev nias yuav tsum tau. Ntxiv rau lub siab, lwm yam tsis xws li extrusion ceev, khoom kub, khoom ntev, thiab kev tsim khoom ntev, thiab kev tsim khoom ntev yuav tsum tau txiav txim siab rau kev ua kom tiav txias. Tag nrho cov tsis muaj kev cuam tshuam rau qhov zoo thiab raug ntawm cov khoom lag luam uas tau tshwm sim.

Ntxiv rau cov hlau, txias extrusion kuj tseem siv rau lwm cov ntaub ntawv xws li plastics, ceramics, xws li cov zaub mov, xws li cov zaub mov, xws li cov nqaij hnyuv, khoom qab zib, thiab lwm yam.

Extrusion yog ib txheej txheem sib xyaw ua ke nyob rau hauv uas ib tug block ntawm cov hlau yog nyem kom tau txais kev txo qis hauv lub cheeb thiab nce ntxiv nyob rau hauv qhov ntev ntawm cov hlau thaiv. Cov khoom lag luam muaj txiaj ntsig cov kev xav hla ntu. Extrusion Puav Pheej muaj cov qauv ntawm axisympric (symmetrical hais txog ib qho axis). Tuag ntawm cov voj voog ntawm cov kab ke sib nrug sib nrug yog siv rau kev extrusion. Extrusion ib txwm muaj feem koom nrog kev sib hlub siab. Loj hydajtatic kev ntxhov siab hauv kev zam kev pab hauv cov txheej txheem los ntawm kev txhim kho duction ntawm cov khoom.

Cov hlau zoo li txhuas, uas tau yooj yim ua haujlwm tau, tuaj yeem muab tso rau hauv chav tsev kub. Lwm yam nyuaj los ua haujlwm cov hlau yog ib txwm kub kub extruded lossis sov extruded. Ob lub vojrular ib puag ncig thiab cov chaw uas tsis yog-ncig tuaj yeem tau los ntawm extrusion. Raws, cov ces kaum, pas nrig, pas nrig, lub qhov rooj thav duab, cov thav duab qhov rooj, cov hlab, thiab txhuas fins yog qee qhov chaw extruded. Nyuaj rau cov ntaub ntawv xws li cov hlau, cov alloys alloys tau txais kev sib tsoo vim yog cov kev ua txhaum ntawm billet thiab cov thawv extrusion. Extrusion cov txiaj ntsig hauv cov qauv nplej zoo dua, qhov tseeb zoo dua qub, thiab saum npoo ntawm cov khoom siv. Tsawg dua wastage ntawm cov khoom nyob rau hauv extrusion yog lwm qhov txaus nyiam ntawm extrusion.

Cov kev siv ntawm extrusions tas li nce vim tias muaj peev xwm tsim cov npov ntev ntev, ntau zaus nrog cov crlex hla kev. Nyob ntawm cov alloy, extrusions pab kev thauj mus los, tsim kho, tshuab, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob. Extrusions yog siv rau cov khoom siv ruaj, khoom siv cua, cua sov thiab cua txias thiab cov roj av ntau lawm, thiab kev tsim khoom ntawm lub zog nuclear. Xyaum txhua cov hlau tuaj yeem raug extruded, tab sis extrudability sib txawv nrog qhov deformation thaj chaw ntawm cov hlau. Cov hlau muag muag tau yooj yim mus ntxiv. Nyuaj (los yog siab-muaj zog) yuav tsum muaj billet ntau dua kub thiab extruding nias nrog rau cov presses siab dua thiab tuag.
