Dab tsi yog qhov ntsia hlau thoob ntawm extruder?
May 13, 2024
Lub taub hau ntawm lub extruder yog ib qho tseem ceeb ntawm cov khoom siv extrusion molding, uas ua ke txiav txim siab qhov ua tau zoo thiab cov khoom zoo ntawm extruder.
Cov ntsia hlau yog lub hauv paus tseem ceeb ntawm extruder, thiab nws cov qauv tsim thiab cov qauv muaj qhov cuam tshuam loj rau cov txheej txheem extrusion. Feem ntau hais lus, screws yog tsim los rau hauv peb seem: seem pub, seem compression, thiab seem homogenization. Ntu kev pub mis yog lub luag haujlwm rau kev xa cov khoom siv, ntu compression compacts thiab softens cov ntaub ntawv, thaum tso tawm cov cua nkag. Cov seem homogenization ntxiv pressurizes thiab sib tov cov ntaub ntawv los ua ib tug tag nrho ntws lub xeev.
Txoj haujlwm ua haujlwm ntawm cov ntsia hlau
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub hau ntswj muaj ob qho tib si mechanical thiab thermal teebmeem. Nyob rau hauv qhov kev txiav txim ntawm cov ntsia hlau, cov khoom siv roj hmab tau dhau los ua cov txheej txheem xws li kev pub mis, kev cog lus, softening, thiab sib tov, thaum kawg tsim cov kua dej khov. Thaum lub sijhawm ua haujlwm no, kev sib hloov ntawm cov ntsia hlau txhawb kev khiav ntawm cov khoom siv roj hmab thiab sib npaug extrudes nws los ntawm lub taub hau channel nrog lub peev xwm thiab siab.
Lub taub hau ntsia hlau yog hais txog qhov tig ntawm cov ntsia hlau, uas yog lwm qhov tseem ceeb ntawm cov extruder. Cov duab geometric thiab qhov loj ntawm cov ntsia hlau tuaj yeem sib txawv raws li cov ntawv thov tshwj xeeb. Piv txwv li, qee zaum, pob tshab screws tuaj yeem muab tso rau ntawm cov hlau ntsia hlau los saib xyuas lub xeev ntawm cov khoom.
Kev xaiv thiab tu cov ntsia hlau chim
Thaum xaiv cov ntsia hlau, nws yog ib qho tsim nyog yuav tau xav txog cov yam ntxwv ntawm cov khoom siv thiab cov kev xav tau ntawm cov khoom extruded. Kev kho saum npoo ntawm cov ntsia hlau chim kuj tseem ceeb heev. Cov kev kho mob feem ntau muaj xws li nitriding, nyuaj soldering, thiab tshuaj tsuag vuam ntawm cov alloys nyuaj, uas tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion kuj ntawm cov ntsia hlau chim.
Thaum siv, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev saib xyuas tsis tu ncua thiab ntxuav lub taub hau ntsia hlau kom tswj nws txoj haujlwm zoo. Tshwj xeeb tshaj yog tom qab siv ntev, cov tshuaj tiv thaiv xeb yuav tsum tau siv los tiv thaiv xeb ntawm cov ntsia hlau chim.
Qhov sib txawv ntawm cov ntsia hlau thiab lub thoob
Qhov haum ntawm cov ntsia hlau thiab lub thoob yog qhov tseem ceeb heev, thiab txoj kab uas hla ntawm lawv ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem extrusion thiab qhov zoo ntawm cov khoom. Raws li kev siv zuj zus, qhov chaw ua hauj lwm ntawm cov ntsia hlau thiab lub thoob yuav maj mam poob, thiab kev kho yuav tsum tau ua, xws li tshuaj tsuag cov khoom hnav-resistant alloys los yog hloov cov khoom tshiab.
Lub taub hau ntawm lub extruder yog ib qho tseem ceeb ntawm kev sib koom ua ke thiab kev sib koom ua ke, thiab lawv cov qauv tsim thiab kev saib xyuas muaj kev cuam tshuam ncaj qha rau kev ua tau zoo thiab cov khoom zoo ntawm cov txheej txheem extrusion molding.
