Ua rau Brittleness hauv PET Sheets
Qhov ua rau brittleness hauv cov ntawv PET yog qhov nyuaj thiab tuaj yeem raug ntaus nqi rau ntau yam tseem ceeb:
1. Kev kho cua sov ntau dhau Thaum lub sij hawm tsim cov ntawv PET, kev kho cua sov yuav tsum tau ua. Txawm li cas los xij, yog tias kev kho cua sov ntau dhau, nws tuaj yeem ua rau muaj kev kub ntxhov ntau dhau ntawm crystallization, ua rau daim ntawv ua nkig thiab ua rau tawg.
2. Degradation ntawm Additives Ntau yam additives xws li plasticizers, stabilizers, thiab xim masterbatches tau muab tso rau hauv cov ntawv PET. Kev degradation ntawm cov additives no tuaj yeem ua rau poob ntawm daim ntawv qhov qub toughness, ua rau nws yooj yim dua. Tsis tas li ntawd, yam xws li kev siv ntau dhau, kev siv tsis zoo, lossis kev ua tsis zoo ntawm cov khoom siv ntxiv tuaj yeem cuam tshuam rau qhov zoo ntawm cov ntawv PET.
3. Kev cia khoom tsis raug Lub chaw cia khoom muaj feem cuam tshuam rau cov nplooj ntawv PET zoo. Yog tias khaws cia rau hauv cov xwm txheej uas muaj qhov kub thiab txias, cov nplooj ntawv PET tuaj yeem raug oxidation lossis decomposition tshwm sim, ua rau brittleness.
4. Cov Txheej Txheem Ntau Lawm Cov teeb meem kev tuav tsis raug thaum lub sijhawm tsim khoom kuj tuaj yeem cuam tshuam qhov zoo ntawm cov ntawv PET. Cov yam ntxwv xws li txheej txheem extrusion, kev tswj kom txias, thiab kev hloov siab tuaj yeem hloov cov qauv sab hauv ntawm daim ntawv, uas ua rau poob ntawm cov khoom siv dag zog thiab nce brittleness.
Kev Tiv Thaiv Kev Ntsuas rau PET Sheet Brittleness
Txhawm rau tiv thaiv brittleness hauv cov ntawv PET, ob peb kauj ruam tuaj yeem ua:
1. Tswj kev kho cua sov kub Thaum lub sij hawm tsim khoom, nws yog ib qho tseem ceeb kom ua tib zoo tswj cov kev kho cua sov thiab lub sij hawm kom tsis txhob muaj crystallization ntau dhau, uas tuaj yeem ua rau brittleness.
2. Kev Tsim Nyog Ntxiv ntawm Cov Khoom Siv Ntxiv Ntxiv ua lub luag haujlwm tseem ceeb hauv cov ntawv PET zoo. Nws yog ib qho tseem ceeb los xaiv thiab ntxiv lawv kom tsim nyog raws li qhov xav tau tiag tiag. Tsis tas li ntawd, kev ntsuas tsis tu ncua yuav tsum tau ua los saib xyuas qhov zoo ntawm cov khoom ntxiv kom tsis txhob degradation uas tuaj yeem cuam tshuam rau daim ntawv lub zog.
3. Tswj Kev Tswj Xyuas Cov Txheej Txheem PET cov ntawv yuav tsum muab khaws cia rau hauv qhov chaw qhuav, qhov cua zoo, thiab cov dej tsis zoo, tsis txhob raug kub thiab av noo. Rau cov nplooj ntawv khaws cia ntev ntev, cov txheej txheem ziab tuaj yeem siv los txo cov dej noo.
4. Ua kom muaj kev tsim khoom tsim nyog Thaum lub sijhawm tsim khoom, cov neeg ua haujlwm yuav tsum ua raws li cov txheej txheem tsim nyog los tiv thaiv cov teeb meem tshwm sim los ntawm cov txheej txheem extrusion, kev tswj kom txias, lossis kev hloov siab uas tuaj yeem cuam tshuam rau cov qauv sab hauv thiab kev ua haujlwm ntawm cov ntawv PET.
5. Cov nplooj ntawv PET yog cov khoom ntim ua tau zoo, tab sis brittleness yog ib qho teeb meem tshwm sim hauv kev siv tswv yim. Txhawm rau kom tsis txhob brittleness, ceev faj yuav tsum tau them nyiaj rau kev tswj hwm ntawm kev tsim khoom thiab kev siv, xws li kev kho cua sov, kev xaiv ntxiv thiab ntau npaum li cas, thiab kev cia khoom. Los ntawm kev tswj hwm cov xwm txheej no, nws muaj peev xwm tsim cov ntawv PET nrog kev ua haujlwm ruaj khov.
Qhov no Tsis Siv Neeg Peb Qhov Chaw Yas Siab Thermoforming Tshuab yog tsim los ntawm ntau yam ntim yas (qe tais, ntim txiv hmab txiv ntoo, ntim khoom noj, ntim ntim, thiab lwm yam) nrog cov ntawv thermoplastic, xws li PS, PET, HIPS, PP, PLA, thiab lwm yam
