Hauv kev siv txhua hnub, cov yeeb yaj kiab npuas ua kom pom cov teeb meem xws li cov laj thawj tuab thiab tsis sib xws los ntawm cov laj thawj hauv qab no thiab tuaj yeem daws teeb meem raws li:
- Cov Khoom Siv Khoom Siv Raw
Qhov sib txawv ntawm cov ntaub ntawv raw: cob cov ntaub ntawv raw los ntawm cov khoom sib txawv los yog nrog cov txiaj ntsig sib txawv, xws li melt index thiab ntom ntom ntom. Sib tov cov ntaub ntawv raw nrog cov khoom sib txawv tuaj yeem ua rau cov txheej txheem tsis sib xws thaum lub sijhawm ua kom tiav, cuam tshuam npuas thiab cov yeeb yaj kiab tuab. Piv txwv li, cov ntaub ntawv raw nrog qhov qis melt invide plhaw maj mam, lub peev xwm tuab yeeb yaj kiab, thaum rov ua yeeb yaj kiab yog qhov tseeb rau cov khoom muaj txiaj ntsig.
Cov khoom siv raw tau ntub dej: cov khoom siv raw tuaj yeem ua ntub dej thaum lub sijhawm cia thiab muaj ntau noo noo. Thaum cov roj kub ntxiv, noo noo sai vaporizes, tsim cov roj tsis tu ncua uas ua rau muaj kev sib txuam ntawm cov khoom sib txawv thiab cuam tshuam zaj duab xis.
Kev daws: nruj tswj qhov zoo ntawm cov ntaub ntawv raw los ntawm kev siv cov ntaub ntawv raw los ntawm tib cov chaw tsim khoom, batch, thiab muaj kev ua tau ruaj khov. Them sai sai rau cov dej noo-pov thawj thaum lub sijhawm khaws cia thiab tag nrho qhuav cov ntaub ntawv raw ua ntej siv cov khoom siv kom ntub dej kom tshem tawm noo noo.
- Cov Khoom Uas Tsis Muaj Peev Xwm Parameter Chaw
Kev tswj qhov kub thiab txias: Qhov kub ntawm cov extruders, pwm, thiab lwm yam tsis tsim nyog. Yog tias qhov ntsuas kub siab dhau thiab lub resin yog kua yog ib yam nkaus thiab ua kom tawg lossis sib tshuam thaum lub sij hawm moulding txheej txheem, ua rau cov npuas tsis sib xws. Yog hais tias qhov ntsuas kub tsawg dhau, lub resin yuav tsis muab tag nrho, ua npuas tsim nyuaj thiab ua rau cov yeeb yaj kiab tsis ruaj khov. Piv txwv li, yog tias cov pwm kub tsis muaj tsawg, cov yeeb yaj kiab saum npoo yuav ntxhib thiab cov npuas yuav sib txawv.
Kev tswj hwm siab: tsis ruaj khov los yog tsis sib xws extrusion siab tuaj yeem hloov lub pas dej cob kev nrawm thiab ntws. Yog tias lub siab siab dhau lawm, cov npuas tej zaum yuav pluav, ua rau lawv ua me. Yog tias lub siab yog tsawg dhau, lub resin yuav tsis extrude smryly, uas ua rau tsis muaj tseeb zaj duab xis tuab.
TRAction ceev: lub traction nrawm tsis phim rau kev extrusion ceev. Yog hais tias lub traction nrawm nrawm heev, zaj duab xis yuav ncab, ua kom nws thinner thiab elongating npuas. Yog hais tias lub traction nrawm yog qeeb heev, zaj duab xis yuav nthuav tawm thiab ua tuab dua, thiab lub npuas yuav deform vim yog extrusion.
Kev daws: Teeb ntsuas kub ntawm txhua qhov sib xyaw kom raug raws li cov yam ntxwv ntawm cov khoom siv Raw thiab cov txheej txheem ntau lawm, thiab siv cov sensors kom saib xyuas thiab kho kom haum. Tsim kom raug kho qhov extrusion siab kom ntseeg tau siab ruaj khov thiab nruab lub siab tswj system rau kev kho kom haum. Phim lub traction nrawm yog qhov tseeb raws li qhov nrawm nrawm, zoo-sib zog nws los ntawm kev kho kom haum nrawm, thiab txuas ntxiv mus rau cov txheej txheem thaum lub sijhawm tsim khoom.
- Tsis ua haujlwm lossis hnav cov khoom siv tshuab
Pwm Hnav: Tom qab siv ntev lawm, Mouldong River channel, tuag lub qhov ncauj, thiab cuam tshuam nrog cov yeeb yaj kiab tsis sib xws, thiab cuam tshuam rau cov hmoov nplej ua npuas. Piv txwv li, tuag lub qhov ncauj hnav tuaj yeem ua rau cov zaj duab xis ntug tuab los txawv los ntawm nruab nrab.
Cov menyuam cov teeb meem: cov nplaim hluav taws xob xws li lub zog chais thiab cov roj hmab cov menyuam yuav tsis sib xws, hnav, los yog inflexible. Tsis ncaj rau cov menyuam yaus tuaj yeem ua rau tsis sib luag ntawm zaj duab xis thaum nws dhau mus, ua rau muaj kev hloov pauv ntawm zaj duab xis tuab. Cov txiv hmab txiv ntoo inflexible tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm lub traction ceev, ua rau inconistent zaj duab xis thiab cov npuas tsis txawv thiab tsis sib xws.
Kev daws: Txheeb xyuas cov hnav ntawm cov pwm, kho lossis hloov cov khoom hnav kom raws sijhawm. Tshawb xyuas qhov chaw zoo thiab kev sib hloov ntawm chais, txhuam thiab kho cov chais nrog kev sib hloov lossis kev txij nkawm tsis zoo, thiab ua haujlwm zoo ntawm cov chais.
- Cov Khoom Siv Hluav Taws Xob Tsis Txaus Ntseeg
Cua Nozzle thaiv lossis kev puas tsuaj: Cov cua nozzle ntawm cov yeeb yaj kiab npuas ua lub luag haujlwm rau hauv cov yeeb yaj kiab los ua npuas. Yog hais tias lub nozzle yog txhaws, tus nqi ntawm cov huab cua txhaj yuav tsis sib xws, ua rau tsis muaj pob zeb tsis sib xws. Yog hais tias lub nozzle raug puas ntsoog, huab cua tej zaum yuav xau lossis hloov kev txhaj tshuaj, cuam tshuam rau kev tsim npuas.
Cov cua tsis ruaj khov: tsis ruaj khov cua siab hauv cov pa hluav taws xob ua kom muaj kev hloov pauv mus rau hauv zaj duab xis, ua rau cov pa npuas sib txawv.
Kev daws: ntxuav lub nozzle tsis tu ncua los tiv thaiv impurities los ntawm txhaws nws, kos yog lub nozzle puas, thiab hloov nws raws sijhawm. Nruab ib qho cua siab stabilization ntaus ntawv, xws li lub siab tswj hwm valve, kom ntseeg tau tias qhov ruaj khov ntawm huab cua muab lub kaw lus thiab saib xyuas cua siab hloov hauv lub sijhawm.
