PPSU (Polyphenylsulfone) yog ib qho kev ua haujlwm siab - thermoplastic siv rau hauv cov ntawv thov xws li cov khoom siv kho mob thiab lub raj mis pub menyuam mos. Nws kev ua haujlwm yuav tsum muaj kev paub tshwj xeeb thiab khoom siv. Kab lus no delves rau hauv cov kev tswj hwm tseem ceeb tsim nyog rau kev ua tiav PPSU lub raj mis molding.
PPSU sawv tawm rau nws qhov tshwj xeeb toughness, tshuaj tiv thaiv, thiab muaj peev xwm tiv taus rov ua kom tsis muaj menyuam, ua rau nws zoo tagnrho rau cov menyuam mos lub raj mis. Txawm li cas los xij, nws qhov kub ua haujlwm siab (feem ntau 360-380 degree) thiab rhiab heev rau cov dej noo tam sim no muaj teeb meem loj. Kev ziab los yog kev tswj qhov kub tsis sib haum tuaj yeem ua rau muaj xim tsis zoo, brittleness, lossis kev ntxhov siab sab hauv, cuam tshuam cov khoom ncaj ncees.
TYM qhov kev mob siab rau PPSU kev txhaj tshuaj molding daws daws cov teeb meem no lub taub hau -rau. Kev sib xyaw ua ke, siab - lub peev xwm desiccant tshuab ziab kom ntseeg tau tias cov khoom siv noo noo qis dua 0.02%, ib qho tseem ceeb rau kev tiv thaiv hydrolytic degradation thaum lub sij hawm yaj. Lub thoob tsim muaj ntau yam, precisely tswj cov cua sov zones ua ke nrog optimized ntsia hlau geometry, kom ntseeg tau tias zoo melting thiab txo lub sij hawm nyob rau hauv lub ncov kub los tiv thaiv thermal degradation.
Tsis tas li ntawd, peb cov tshuab suav nrog tiag tiag - lub sijhawm ntsuas kab noj hniav. Qhov no tso cai rau cov txheej txheem ua kom zoo - kho qhov kev txhaj tshuaj, ua kom muaj kev sib xyaw ua ke thiab ntim khoom, uas yog qhov tseem ceeb rau kev tswj xyuas qhov tseeb thiab cov khoom siv kho tshuab uas xav tau rau cov khoom noj pub mis rau menyuam mos. Qhov kev tswj hwm qib no hloov pauv qhov nyuaj ntawm PPSU kev ua haujlwm rau hauv kev kwv yees, siab - ua haujlwm zoo.
