Dab tsi yog Extrusion Moulding?
Extrusion molding, tseem hu ua extrusion hauv kev ua yas, siv hydraulic siab los quab yuam cov khoom los ntawm pwm, tsim cov ntu txuas ntxiv ntawm ntau yam duab. Cov txheej txheem no suav nrog cua sov cov khoom raws li nws raug thawb los ntawm ib lub hau ntswj los ntawm lub thoob, uas ua rau tsim cov khoom txuas ntxiv lossis cov khoom ib nrab. Extrusion molding, thev naus laus zis thaum ntxov hauv kev ua cov polymer, tau hloov zuj zus dhau 100 xyoo dhau los rau hauv txoj kev ua tau zoo, tsis tu ncua, tus nqi qis nrog kev siv dav. Tam sim no nws yog txoj hauv kev siv ntau tshaj plaws hauv kev lag luam polymer vim nws yoog raws, tus nqi ntau lawm, thiab ntau yam.
Cov txheej txheem yooj yim hauv Extrusion Moulding
1. Pub noj
Cov khoom yas yog pub rau hauv lub hopper thiab txav mus rau hauv cov ntsia hlau raws hauv qab lub ntiajteb txawj nqus los yog nrog kev pab los ntawm feeder, nce mus rau lub taub hau tuag.
2. Kev xa tawm
Raws li cov yas nkag mus rau hauv cov ntsia hlau channel, nws txav mus rau pem hauv ntej nrog txhua tus ntsia hlau tig. Qhov tseeb conveyance tus nqi nyob ntawm qhov sib txhuam coefficients ntawm cov yas tiv thaiv lub thoob thiab ntsia hlau. Kev sib txhuam siab dua nrog lub thoob los yog kev sib txhuam qis nrog cov ntsia hlau ua rau cov yas txav mus rau pem hauv ntej.
3. Compression
Compression yog qhov tseem ceeb hauv extrusion molding. Yas yog cov khoom siv hluav taws xob tsis zoo ntawm cov cua sov, thiab txhua qhov sib txawv ntawm cov khoom tuaj yeem cuam tshuam kev hloov hluav taws xob, cuam tshuam rau cov nqi melting. Compression pab tshem tawm cov pa roj tawm ntawm cov khoom siv, tiv thaiv qhov tsis xws luag, thiab ua kom cov khoom ntom ntom los ntawm kev tswj xyuas qhov system siab.
4. Melting
Nrog kev nce siab, qhov txav cov khoom yas sib tiv tauj thiab rubs tawm tsam cov phab ntsa rhuab phom, tsim ib zaj duab xis nyias. Cov yeeb yaj kiab no tau muab tshem tawm los ntawm cov ntsia hlau thaum nws txav mus, tsub zuj zuj nyob rau hauv pem hauv ntej ntawm cov ntsia hlau flights thiab tsim ib lub pas dej ua ke.
5. Sib tov
Nyob rau hauv kev kub siab, cov khoom siv yog compacted rau hauv ib tug tuab plug. Kev sib xyaw tsuas yog nyob nruab nrab ntawm cov txheej txheem molten, tsis nyob hauv cov khoom ntsaws.
6. Exhausting
Qhov cua tshuab yog qhov tseem ceeb los tshem tawm cov pa roj thiab cov vapors uas tsim thaum lub sij hawm extrusion txheej txheem. Kev tso cua kom zoo ua kom cov khoom kawg ua tau zoo los ntawm kev tiv thaiv qhov khoob thiab qhov tsis xws luag.

Cov ntsiab lus tseem ceeb hauv Extrusion Moulding
Pre-startup Checks: Tshawb xyuas lub thoob, hopper, thiab fasteners, kom ntseeg tau tias tag nrho cov khoom muaj kev ruaj ntseg. Lubricate raws li qhov tsim nyog thiab ntxuav cov khoom siv.
Tsawg-ceev Pib: Thaum pib ua haujlwm lub hau ntswj ntawm qhov ceev, saib xyuas qhov tsis sib xws hauv kev ua haujlwm ntawm lub cev muaj zog lossis lub suab.
Luv luv Tsis-Load Trials: Txwv cov ntsia hlau mus sib hais mus rau 30 feeb ua ntej txuas cov pwm tsim, lubricating cov pwm bolts kom yooj yim tshem tawm.
Kev pub mis maj mam: Pib nrog lub hau ntswj qis thiab cov khoom noj sib npaug, saib xyuas qhov hloov pauv ntawm lub cev muaj zog tam sim no.
Temperature Monitoring: Tsis tu ncua xyuas cov kabmob kub, kom tsis txhob muaj kev sib cuag ncaj qha nrog cov khoom txav thaum lub sijhawm ua haujlwm.
Surface Roughness Solutions: Ua kom qhov kub thiab txias, kho cov ntsia hlau ceev, hloov cov lim dej, thiab siv cov khoom kom qhuav kom tsis txhob muaj qhov tsis xws luag.
