Vim yog cov yas yas ntawm cov hluav taws xob, lub cev muaj zog, thiab cov kev ua tau zoo dua hauv tsheb, cov kev ua tau zoo dua yog muab tso rau kev ua haujlwm nylon thiab kub ua tsis taus. Qhov no qhib lub prelude mus rau kev tshawb nrhiav thiab kev txhim kho thiab kev thov ntawm high-kub nylon.
High chim iav Fiber Reinferced High kub nylon ppa yog ib qho ntawm cov khoom tshiab uas tau nyiam ntau tshaj plaws thiab cov khoom siv tau zoo tshaj plaws. Cov iav fiber cuam tshuam cov khoom kub nylon Tshwj xeeb tshaj yog rau lub cav tsheb ua lag luam, uas yuav tsum tau daws cov kev xaiv nruj, high-kub nylon tau maj mam ua qhov kev xaiv zoo tshaj plaws rau cov ntaub ntawv hauv tsheb. Dab tsi yogtxawvTxog qhov kub nylon?
1, Zoo heev Txhua Yam
Piv nrog tsoos aliphatic nylon (pa6 / pa66), kub nylon tau pom tseeb hauv cov khoom siv ntawm cov khoom lag luam thiab nws cov khoom cua ua kom tsis taus. Piv nrog yooj yim tshuab zog, kub nylon muaj tib lub khob fiber ntau cov ntsiab lus ntawm lub premise. Nws yog 20% siab dua li ib txwm siv nylon, uas tuaj yeem muab cov kev daws teeb meem ntau dua rau lub tsheb.

2, ultra-siab kub siab ua haujlwm
Nyob rau hauv lub premical deformation kub ntawm 1.82MPA, qhov kev kub fiber ntau ntxiv tau tuaj yeem ncav cuag 280 ° K, Thaum cov tsoos Aliphatic pa66 30% GF yog txog 255 ° C. Thaum cov khoom yuav tsum tau ua ntxiv rau 200 ° C, nws yog qhov nyuaj rau cov khoom lag luam ib txwm muaj, tshwj xeeb yog lub cav cov khoom lag luam uas muaj qhov kub thiab txias ntev. Nyob rau hauv ib puag ncig ntub, thiab nws yuav tsum tau tiv taus cov corrosion ntawm cov roj txheem roj.
3, Zoo heev Sab Muaj Peev Xwm
Cov dej nqus tus nqi ntawm aliphatic nylon yog tus ncej dej siab yuav ncav cuag 5%, ua rau muaj cov khoom lag luam qis heev ntawm cov khoom lag luam, uas yog qhov tsis zoo rau qee qhov khoom lag luam siab. Qhov kev faib ua feem ntawm cov pab pawg nyob rau hauv cov nylon siab nylon txo, cov dej nqus dej tseem yog ib nrab ntawm cov txiv ntoo zoo nkauj heev yog qhov zoo dua.
4, zoo heev tshuaj lom neeg tiv thaiv
Txij li thaum cov khoom siv peripheral ntawm cov khoom siv tsis sib haum, tshwj xeeb yog cov tshuaj ntsuab, tshwj xeeb yog cov tshuaj lom neeg muaj txiaj ntsig zoo rau cov txiaj ntsig corrosive ntawm aliphatic polyamide, thaum qhov siab kub ntawm cov tshuaj tshwj xeeb Tus qauv ntawm Nylon ua rau qhov kev ua tsis luv no, yog li cov tsos ntawm high-kub nylon tau tsa ib puag ncig lub cav rau qib tshiab.

Automotive kev lag luam kev lag luam
Txij li thaum PPA tuaj yeem muab cov cua sov distortion kub ntawm dhau 270 ° C, nws yog qhov zoo tshaj plaws engineering seem hauv kev lag luam, tshuab, thiab hluav taws xob / hluav taws xob kev lag luam. Nyob rau tib lub sijhawm, PPA kuj zoo tagnrho rau qhov uas yuav tsum muaj kev ncaj ncees ntawm cov qauv kev ncaj ncees thaum luv luv.
Automotive hood ua los ntawm cov nylon kub siab
Nyob rau tib lub sijhawm, cov yas yas ntawm cov hlau seem xws li cov roj tshuab, tso pa tawm ntawm lub cav tau hloov pauv, thiab cov kev xav tau rau cov ntaub ntawv muaj kev nruj dua. Cov kub ua hauj, durability, thiab tshuaj tua kuj ntawm cov dhau los general congineering plastics tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Tsis tas li ntawd, qhov kev kub siab nylon kub ntawm kev ua tiav, kev siv tau dawb ntawm cov txheej txheem pub dawb, thiab txo qhov hnyav thiab corrosion tsis kam.
Txij li thaum cov nylon kub muaj peev xwm tiv nrog lub zog siab, kub thiab lwm qhov chaw hnyav, nws yog qhov haum rau eThaj chaw ngine (xws li lub cav npog, hloov chaw thiab txuas) thiab kis tshuab (xws li kev tso pa taws cov tshuab) thiab cov khoom siv cua.
Txawm li cas los xij, cov khoom siv nylon kub tuaj yeem nqa ntau cov txiaj ntsig rau ppa, yog tias muaj kev hloov kho ntawm PPA, thiab lwm yam, yog li nws haum rau ntau yam kev siv xav tau cov dej siab kub ua hauj. Muaj cov kev cia siab.
