High-kev ua tau zoo engineering yas-PPO polyphenylene ether khoom.Cov khoom siv hluav taws xob zoo heev, lub zog muaj zog thiab nkag siab thiab lwm yam, muab cov ntaub ntawv PPO nrog cov ntawv thov zoo hauv tsheb, khoom siv hluav taws xob, 5G thiab lwm yam.
Vim tias muaj cov viscosity siab melting thiab fluidity tsis zoo ntawm PPO cov ntaub ntawv, hloov PPO cov ntaub ntawv (MPPO) yog tam sim no nyob rau hauv kev ua lag luam, thiab PPO alloy hloov cov ntaub ntawv yog cov tseem ceeb tshaj kev hloov kho txoj kev.
Cov hauv qab no yog cov ntaub ntawv hloov kho PPO alloy ntawm lub khw, cia peb saib:
01.PPO / PA alloy khoom
PA cov khoom siv (nylon) muaj cov khoom siv zoo heev, hnav tsis kam, nws tus kheej lubrication, kev ua haujlwm yooj yim thiab lwm yam ntxwv, tab sis lub ncov qaumteb qabteb siab nqus dej yog qhov loj, thiab qhov loj ntawm cov khoom hloov pauv zoo heev tom qab nqus dej.
Cov khoom siv PPO muaj qhov nqus dej tsawg heev, qhov zoo ntawm qhov ruaj khov, thiab kev nkag siab zoo heev, tab sis kev ua haujlwm tsis zoo.Nws tuaj yeem hais tias PPO / PA alloy cov khoom sib txuas ua ke cov khoom zoo ntawm ob.Cov khoom siv hlau no kuj yog ib hom alloy nrog kev loj hlob sai thiab ntau yam ntawm PPO alloys.Nws yog tsuas yog siv rau nws pib qhov chaw, xws li lub log npog, cav peripheral qhov chaw, thiab lwm yam.
Nws yuav tsum tau muab sau tseg tias amorphous PPO thiab crystalline PA yog thermodynamically incompatible, thiab lawv cov khoom sib xyaw yooj yim yog yooj yim delaminate, muaj cov khoom siv tsis zoo, thiab muaj txiaj ntsig zoo;kev ntsuas tsim nyog yuav tsum tau coj los txhim kho kev ua haujlwm ntawm ob qho tib si.compatibility los txhim kho nws cov kev ua tau zoo.Ntxiv qhov tsim nyog compatibilizer thiab siv cov txheej txheem tsim nyog tuaj yeem txhim kho kev sib raug zoo ntawm PPO thiab PA.
02 ib.PPO / HIPS alloy khoom
Cov khoom siv PPO muaj kev sib raug zoo nrog cov khoom siv polystyrene, thiab tuaj yeem sib xyaw rau hauv ib qho kev faib ua feem yam tsis muaj kev txo cov khoom siv ntau dhau.
Qhov sib ntxiv ntawm HIPS rau cov khoom siv PPO ua rau muaj kev cuam tshuam lub zog.Feem ntau, txhawm rau txhawm rau txhim kho qhov cuam tshuam lub zog ntawm lub cev thiab txhim kho kev ua tau zoo tag nrho, elastomers feem ntau tau ntxiv los ua cov hloov kho tawv, xws li SBS, SEBS, thiab lwm yam.
Ntxiv mus, PPO nws tus kheej yog ib hom polymer uas yog nplaim hluav taws, yooj yim tsim cov pa roj carbon monoxide, thiab muaj nws tus kheej tua hluav taws.Piv nrog rau HIPS ntshiab, cov nplaim hluav taws tsis zoo ntawm PPO / HIPS alloys kuj tuaj yeem txhim kho tau zoo.Nrog rau qhov nce ntawm PPO, lub melting dripping thiab haus luam yeeb ntawm cov polymer alloy thaum lub sij hawm combustion maj mam txo, thiab cov kab rov tav combustion theem maj nce.
Daim ntawv thov tseem ceeb: cov khoom siv hluav taws xob tiv thaiv hluav taws xob ntawm lub tsheb, cov cuab yeej hluav taws xob thiab cov tshuab hluav taws xob, cov khoom siv hluav taws xob ua kom tsis muaj menyuam, thiab lwm yam.
03.PPO / PP alloy khoom
Tus nqi thiab kev ua tau zoo ntawm PPO / PP alloys yog nruab nrab ntawm cov yas engineering, xws li PA, ABS, iav fiber ntau PP, hloov PET thiab PBT, thiab lwm yam, thiab lawv tau ua tiav qib siab dua ntawm kev nruj, toughness, kub tsis kam thiab nqe.zoo tshuav.Cov ntawv thov yog nyob rau hauv kev lag luam tsheb, lub zog, lub thawv ntim khoom, cov tais ntim khoom noj, cov khoom siv thauj khoom (cov twj tso kua mis), thiab lwm yam.
Cov alloys nyiam los ntawm automakers vim tias lawv sib raug zoo nrog lwm cov yas thaum lub sij hawm rov ua dua, piv txwv li lawv tuaj yeem muab sib xyaw thiab rov ua dua nrog lwm cov PP-raws li plastics lossis ntau yam ntawm polystyrene-based plastics.
04 ib.PPO / PBT alloy khoom
Txawm hais tias PBT cov ntaub ntawv muaj cov khoom zoo, tseem muaj cov teeb meem xws li hydrolysis yooj yim, tsis muaj peev xwm tiv taus dej kub ntev, cov khoom ua rau anisotropy, molding shrinkage thiab warpage, thiab lwm yam Alloy hloov kho nrog PPO cov ntaub ntawv tuaj yeem txhim kho ib leeg.kev ua haujlwm flaws.
Raws li kev tshawb fawb txog cov khoom siv alloy, cov khoom siv tsis muaj viscosity PPO yog qhov tsim nyog rau kev sib xyaw nrog PBT cov khoom siv hlau, tab sis nws kuj xav tau kev sib xyaw ua ke rau kev sib xyaw ua ke.
Feem ntau siv los ua cov khoom siv hluav taws xob, khoom siv hluav taws xob thiab lwm yam.
05. PPO / ABS alloy khoom
ABS cov khoom muaj cov qauv PS, uas muaj kev sib raug zoo nrog PPO thiab tuaj yeem sib xyaw ncaj qha.ABS cov khoom tuaj yeem txhim kho qhov cuam tshuam lub zog ntawm PPO, txhim kho kev ntxhov siab tawg, thiab muab PPO electroplatability, thaum tswj hwm lwm yam khoom ntawm PPO.
Tus nqi ntawm ABS yog qis dua li ntawm PPO, thiab cov khoom lag luam muaj ntau.Vim tias ob qho tib si sib koom ua ke thiab cov txheej txheem alloying yog yooj yim, nws tuaj yeem hais tias nws yog lub hom phiaj dav dav PPO alloy, uas yog tsim rau qhov chaw pib, electromagnetic shielding plhaub cov ntaub ntawv, cov khoom siv hauv chaw ua haujlwm, chaw ua haujlwm machinery thiab spinning hlab, thiab lwm yam.
