Hauv kev lag luam khoom noj khoom haus thiab pub khoom noj, kev siv tshuab extrusion, nrog nws cov txheej txheem tshwj xeeb thiab ntau yam kev siv, tau dhau los ua lub zog tseem ceeb. Ntawm ntau cov khoom siv extrusion, ntxaib- ntsia hlau extruder tau maj mam dhau los ua cov khoom lag luam hnub qub vim nws qhov kev ua tau zoo tshaj thiab siv dav.
Txheej txheem cej luam ntawm Extruder Hom
Extruders tuaj yeem muab faib ua ntau hom raws li cov ntaub ntawv uas lawv ua thiab lawv siv. Cov hom muaj xws li pob kws extruders, hmoov extruders, taum extruders, thiab pub extruders. Txawm li cas los xij, ntawm cov extruders, ntxaib - ntsia hlau extruder sawv nrog nws cov ntxaib tshwj xeeb - ntsia hlau qauv thiab kev ua haujlwm siab.
Qhov zoo ntawm Twin -Screw Extruders
Twin-ntsia hlau extruders ntiav ntxaib- ntsia hlau qauv. Ob qhov kev sib txuas ntawm cov ntsia hlau tig hauv lub thoob, extruding, shearing, sib tov, thiab cua sov cov khoom, yog li ua tiav cov txheej txheem extrusion. Nws qhov tshwj xeeb zoo yog:
Kev ua haujlwm siab: Cov ntxaib- cov qauv ntsia hlau muab lub zog extrusion thiab shear zog, tso cai rau cov ntaub ntawv kom huv si sib xyaw thiab ua kom sov hauv lub thoob, yog li txhim kho cov nyhuv puffing thiab cov khoom zoo.
Kev siv dav: Cov ntxaib- ntsia hlau extruder yog tsim rau puffing ntau yam ntaub ntawv, xws li nplej, hmoov, taum pauv, ntses, cws, tsiaj noj, thiab lwm yam, ua tau raws li cov kev xav tau ntawm kev lag luam sib txawv.
Kev ua haujlwm yooj yim: Lub ntxaib- ntsia hlau extruder txais kev tswj hwm kev tswj hwm qib siab, ua haujlwm yooj yim thiab yooj yim, txo kev ua haujlwm nyuaj thiab nqi zog.
Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: Cov khoom siv no muaj kev siv hluav taws xob tsawg thiab tsis muaj suab nrov thaum ua tiav, ua tau raws li cov kev xav tau ntawm kev lag luam niaj hnub rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
Tej teeb meem thiab kev daws teeb meem thaum siv extruder
Txawm hais tias qee qhov teeb meem yuav raug ntsib thaum lub sij hawm siv extruder, tsuav yog peb paub cov txheej txheem kev khiav hauj lwm kom raug thiab cov txheej txheem tu, peb tuaj yeem zam lossis txo qhov tshwm sim ntawm cov teeb meem no. Nov yog qee qhov teeb meem thiab kev daws teeb meem:
Cov kabmob hnav: Tom qab cov khoom siv tau khiav mus rau lub sijhawm, cov kabmob tuaj yeem hnav. Lub sijhawm no, peb yuav tsum tau kho cov kabmob tshem tawm lossis hloov cov kabmob.
Steam backflow: Steam backflow rau hauv lub feeder tuaj yeem ua rau muaj kev thaiv. Yuav kom daws tau qhov no, peb yuav tsum xyuas kom meej tias cov kav dej thiab cov li qub ua haujlwm kom raug kom ntseeg tau tias cov pa tsis ntws rov qab mus rau hauv lub feeder.
Kev tuav raw khoom tsis raug: Kev tuav raw khoom tsis raug tuaj yeem ua rau lub extruder jam. Yog li ntawd, peb yuav tsum tau npaj cov ntaub ntawv raw kom zoo kom ntseeg tau tias qhov tsis xws li ya raws thiab qhov kub thiab txias ua tau raws li qhov xav tau ntawm extruder.
Screw configuration adjustment: Cov khoom sib txawv extruded muaj qhov sib txawv siab, kub, thiab ntsia hlau configuration yuav tsum. Yog li ntawd, peb yuav tsum tau kho cov ntsia hlau configuration raws li cov yam ntxwv ntawm cov khoom sib txawv los xyuas kom meej tias lub extruder tuaj yeem ua cov khoom lag luam raws li qhov yuav tsum tau ua.
