5. Cov nplaim hluav taws zoo, nrog rau tus kheej nyiam, thiab nruab nrab flammability thaum sib xyaw nrog HIPS. Lub teeb yuag, tsis muaj tshuaj lom tuaj yeem siv rau hauv kev lag luam khoom noj thiab tshuaj. Lub teeb tsis zoo, lub sijhawm ntev hauv lub hnub yuav hloov xim.
6. Nws tuaj yeem sib xyaw nrog ABS, HDPE, PPS, PA, HIPS, iav fiber, thiab lwm yam.
PPO yas raw khoom yam ntxwv
A. PPO yas raw khoom uas tsis yog-tshuaj lom, pob tshab, me me ntom ntom, nrog cov khoom siv zoo heev, kev ntxhov siab ua haujlwm, nkag siab, tiv thaiv tshav kub, dej tsis kam, dej tsis kam, chav ua haujlwm, qhov ruaj khov.
B, nyob rau hauv ib tug ntau yam ntawm kub thiab zaus variation, zoo hluav taws xob kev ua tau zoo, tsis muaj hydrolysis, tsim shrinkage tus nqi yog me me, inflammable nrog nws tus kheej-extinguishing, tsis zoo tiv thaiv inorganic acid, alkali, aromatic hydrocarbon, halogenated hydrocarbon, roj thiab lwm yam khoom, yooj yim o los yog kev ntxhov siab tawg.
C. Nws muaj qhov zoo ntawm rigidity siab, siab kub tsis kam, tsis yooj yim rau hlawv, siab zog thiab kev ua tau zoo ntawm hluav taws xob.
D. Polyether kuj muaj qhov zoo ntawm kev puas tsuaj, tsis muaj tshuaj lom thiab muaj kuab paug.
E. PPO yas raw cov ntaub ntawv dielectric tas li thiab dielectric poob nyob rau hauv engineering plastics yog ib tug ntawm cov tsawg tshaj plaws ntau yam, yuav luag tsis cuam tshuam los ntawm kub, av noo, yuav siv tau nyob rau hauv lub teb ntawm tsawg, nruab nrab, high zaus hluav taws xob teb.
F. PPO load deformation kub tuaj yeem ncav cuag 190 ℃, embrittlement kub yog -170 ℃.
G. qhov tsis zoo yog qhov tsis zoo ntawm melting liquidity, ua thiab molding nyuaj.
Daim ntawv thov
PPO qhov kev ua tau zoo txiav txim siab nws daim ntawv thov teb thiab siv ntau yam:
1) MPPO muaj qhov ntom ntom me me, yooj yim rau kev ua haujlwm, thermal deformation kub hauv 90 ~ 175 ℃, cov khoom sib txawv ntawm cov khoom siv, qhov ruaj khov zoo, haum rau kev tsim cov khoom siv hauv chaw ua haujlwm, khoom siv hauv tsev, khoos phis tawj thiab lwm lub thawv, chassis thiab precision qhov chaw.
2) Lub dielectric tsis tu ncua thiab dielectric poob Lub kaum sab xis ntawm MPPO yog qhov qis tshaj ntawm tsib cov khoom siv hluav taws xob dav dav, uas yog, qhov zoo tshaj plaws rwb thaiv tsev thiab zoo tshav kub tsis kam, haum rau kev lag luam hluav taws xob.
Haum rau kev tsim hluav taws xob rwb thaiv tsev qhov chaw siv nyob rau hauv ntub thiab loaded tej yam kev mob, xws li coil moj khaum, raj puag, tswj ncej, transformer shield, relay box, rwb thaiv tsev strut, thiab lwm yam.
3) MPPO dej tsis kam thiab kub tsis kam, dej zoo, haum rau kev tsim cov dej ntsuas, twj.
Cov xov paj siv nyob rau hauv lub Hoobkas textile yuav tsum yog tus lej-resistant. Lub raj xov paj ua los ntawm MPPO muaj lub neej ua haujlwm ntev.
4) Lub dielectric tas li thiab dielectric poob Lub kaum sab xis ntawm MPPO hauv engineering plastics tsis cuam tshuam los ntawm qhov kub thiab txias, thiab qhov kub thiab txias thiab qhov ruaj khov yog qhov zoo, haum rau kev lag luam hluav taws xob.
5) vim yog kev txhim kho ntawm kev lag luam hluav taws xob thiab kev sib txuas lus, xov tooj ntawm tes, laptops, lub koob yees duab ua tau zoo, lub koob yees duab thiab lwm yam xav tau cov roj teeb lithium ion, lithium-ion roj teeb kev lag luam zoo rau kev loj hlob, yog li ntawd, lithium ion roj teeb nrog cov organic electrolyte. ntawm cov ntaub ntawv ntim khoom siv ABS lossis PC, tsim cov roj teeb MPPO txawv teb chaws hauv xyoo 2013, nws qhov kev ua tau zoo dua li ntawm ob lub qub qub.
6) MPPO muaj ntau yam USES nyob rau hauv kev lag luam tsheb, xws li lub dashboard, tiv thaiv tuav, PPO thiab PA alloy, tshwj xeeb tshaj yog rau cov kev ua tau zoo heev specifications rau kev loj hlob sai ntawm cov khoom.
7) Hauv kev lag luam tshuaj, hloov polyphenylene ether tuaj yeem siv los ua cov khoom siv tiv thaiv corrosion; Nws tsis kam mus rau hydrolysis yog tshwj xeeb yog zoo, tab sis kuj acid, alkali, soluble nyob rau hauv aromatic hydrocarbon thiab chlorinated hydrocarbon.
8) Rau cov cuab yeej siv kho mob, tuaj yeem hloov cov hlau tsis muaj steel thiab lwm yam hlau hauv cov dej kub cia tank thiab tso tawm kiv cua sib xyaw ua ke valve.
