Polymer extrusion Mlt twj
Lub polymer extrusion melt twj yog ib tug tseem ceeb uxiliaation khoom nyob rau hauv extrusion moulding txheej ntawm polymer cov ntaub ntawv xws li plastics thiab roj hmab.
Nws yog tsuas yog siv los ua kom ruaj khov rau cov qav taub hau thiab txaus tus nqi thiab txhim kho cov khoom lag luam ntawm cov khoom lag luam. Nws yog dav siv nyob rau hauv kev ntau lawm cov yeeb yaj kiab, kav dej, profiles, thiab lwm yam.
Nws cov qauv tsim yog raws li lub hauv paus ntsiab lus ntawm volumetric conventing thiab tuaj yeem pab tau zoo rau qhov tsis txaus ntseeg ntawm extruder nws tus kheej hauv siab / ntws tswj.
Kom zoo dua ntawm polymer extrusion Mlt twj tso kua mis
Piv nrog cov txheej txheem ib txwm muaj ntawm "extruder ncaj qha txuas nrog lub tshuab raj" thiab cov iav melt zoo nyob rau hauv "precision, thiab txij nkawm nqi"
| Ruaj khov thiab siab | Ntws hloov pauv tuaj yeem tswj tau nyob rau hauv ± 0.3% (tsoos khib nyiab extruder function à 5% {- ± 1%); siab sib txawv tsawg dua lossis sib npaug rau ± 0.5% | 1. Tsis tshua muaj qhov tseeb ntawm cov khoom lag luam, xws li roj teeb separator thickness muaj los ntawm ± 5% rau ± 1%); 2. Raug tshem tawm pwm nyem, cov khoom lag luam luv, lossis nto "ripple" tsis xws luag tshwm sim los ntawm kev hloov siab sai. |
| Haum rau siab viscosity thiab tshav kub - rawv melts | "Tus" Qis shear conveying "cov yam ntxwv ntawm cov iav meshing tuaj yeem siv melts nrog vas aws (xws li PMMA thiab PPS); Nyob rau tib lub sijhawm, nws txo qhov chaw nyob ntawm lub sij hawm melt hauv lub twj tso kua mis (<10s) to avoid high temperature degradation | 1. Excand extrusion cov ntawv thov rau high-}}}}}}}}}}}}} Cov khoom lag luam yas ntxiv thiab cov khoom siv kho mob yooj yim heev); 2. Txo cov daj tua tsiaj ntawm tshav kub- Cov ntaub ntawv rhiab xws li PVC thiab tus tsiaj (YellDowness Index txo los ntawm 20% -30%) |
| Kev haus qis dua thiab muaj txiaj ntsig zoo dua | Nws tuaj yeem txo cov ntsia hlau extruder rov qab siab los ntawm 30% (txo cov ntsia hlau ntxiv ntawm cov extruder los ntawm 10% -25%; Nyob rau tib lub sijhawm, cov extruder tso zis tau nce los ntawm 15% -40%. | 1. Txo kev siv hluav taws xob ib chav ntawm cov khoom lag luam (tshwj xeeb yog rau high {1} Kev lag luam hluav taws xob siab tuaj yeem ncav pua pua txhiab tus KWH); 2. Txhim kho cov cuab yeej siv (txo lub sijhawm kom huv thiab ntxuav kom huv si yog melt degradation) |
Raug daim ntawv thov polymer extrusion MlT twj
1. High {{{-} Cov roj teeb hluav taws xob txig sib cais: {- thickness zam kev tswj (hauv ± 1μm).
2. Kev kho mob tubing ntau lawm: xws li Txoj kev lis ntshav tubing thiab diabsis tubing, yuav tsum tau ua kom cov txheej txheem sab hauv lub taub lim dej thiab dawb huv (pub dawb ntawm qhov teeb meem (pub dawb ntawm kev ua kom muaj teeb meem).
3. Extrusion of High - viscority cov khoom: xws li kev tshwj xeeb enastics uas zoo li kev tiv thaiv qis molecular saw breakage.
4. Multi {{- txheej butruses khoom: xws li siab}
