Polyphenylene Sulfide (PPS) - Tshiab 5G Txoj Haujlwm

 

Polyphenylene sulfide (PPS)yog ib hom thermoplastic tshwj xeeb engineering yas nrog cov khoom zoo. Nws cov yam ntxwv zoo tshaj plaws yog kub tsis kam, corrosion kuj thiab superior mechanical zog.

PPS yog dav siv nyob rau hauv tsheb, hluav taws xob thiab hluav taws xob, machinery kev lag luam, petrochemical kev lag luam, tshuaj kev lag luam, lub teeb kev lag luam, tub rog kev lag luam, aerospace, 5G kev sib txuas lus thiab lwm yam teb, yog ib tug ntawm cov feem ntau lug siv tshwj xeeb engineering plastics.

 

Nrog rau qhov tshwm sim ntawm 5G era, PPS kuj tau nthuav dav rau hauv qhov kev tawm tshiab no.

5G yog tiam thib tsib ntawm kev sib txuas lus xov tooj ntawm tes, kev sib kis ceev yog ntau dua 100 npaug ntawm 4G, yog li 5G cov ntaub ntawv muaj cov kev xav tau siab ntawm dielectric tas li.Feem ntau, qhov permittivity ntawm cov khoom siv cob tsuas yog yuav tsum tau qis dua 3.7 rau 4G cov khoom, thaum lub permittivity ntawm resin composite khoom feem ntau yuav tsum nyob nruab nrab ntawm 2.8 thiab 3.2 rau 5G khoom.

Cov yam ntxwv ntawm PPS

1. Cov khoom cua sov

PPS muaj qhov ua tau zoo thaum tshav kub kub, tshwj xeeb tshaj yog nyob rau hauv high humidity thiab kev ntxhov siab. PPS hluav taws xob rwb thaiv tsev kub tiv thaiv qib nce mus txog F (YAEBFH qib, qib kub tsis kam nce ntxiv). PPS zaj duab xis muaj cov nplaim hluav taws kub siab tshaj plaws (kev tua tus kheej) thaum tsis muaj tshuaj ntxiv. PPS zaj duab xis tshaj 25 hli tau txheeb xyuas raws li UL94 V0 cov khoom siv qib.

2. Mechanical yam ntxwv

Lub zog tensile thiab ua cov khoom ntawm PPS zaj duab xis zoo ib yam li cov PET, thiab PPS zaj duab xis tseem tuaj yeem tuav lub zog siab thiab tawv ntawm qhov kub ntawm -196 ℃, uas tuaj yeem siv los ua cov khoom siv rwb thaiv tsev uas cuam tshuam rau superconductivity.

Tsis tas li ntawd, kev nkag mus ntev thiab kev nqus dej ntawm PPS yog qis dua li ntawm PET zaj duab xis, tshwj xeeb tshaj yog cov nyhuv ntawm cov dej noo ntawm PPS zaj duab xis me me, yog li qhov kev ruaj ntseg ntawm qhov ntev yog qhov zoo heev, uas tuaj yeem hloov PET li cov ntaub ntawv sib nqus, kev yees duab thiab lwm yam duab ntsig txog cov ntaub ntawv hauv zaj duab xis.

3. Cov khoom siv tshuaj

PPS resistant rau feem ntau cov kuab tshuaj organic, ntxiv rau cov concentrated sulfuric acid, concentrated nitric acid impregnation, tsuas yog nyob rau hauv 2-chlornaphthalene, diphenyl ether thiab lwm yam tshwj xeeb solvents saum 200 ℃ tsuas yog pib yaj,nws qhov tsis kam yog thib ob tsuas yog huab tais yas PTFE.

4. Hluav taws xob

PPS muaj cov yam ntxwv ntawm cov hluav taws xob ntau zaus, nws qhov dielectric tsis tu ncua yog qhov ruaj khov nyob rau hauv ntau qhov kub thiab qhov ntau zaus, thiab nws cov dielectric poob lub kaum sab xis me me txaus los sib tw polypropylene. Raws li capacitor dielectric, nws capacitance muaj me ntsis nyob ntawm qhov kub thiab qhov zaus, yog li qhov poob qis capacitor tuaj yeem tau txais.

5. Lwm yam kev ua tau zoo

Qhov nro ntawm PPS zaj duab xis yog me ntsis qis dua li ntawm PET zaj duab xis, tab sis nws kuj tsim nyog rau txheej txheej. Nyob rau hauv rooj plaub uas cov nplaum siv nrog lwm cov yeeb yaj kiab laminates, qhov saum npoo yuav tsum tau kho corona kom nce qhov nro rau 58d / cm.

Lub nto roughness thiab kev sib txhuam coefficient ntawm PPS zaj duab xis tuaj yeem hloov kho raws li lub hom phiaj ib yam li PET. PPS membrane yog ib qho ntawm ob peb cov organic membranes uas yuav siv tau nyob rau hauv periphery ntawm nuclear reactor thiab fusion furnace vim nws siab durability tiv thaiv r ray thiab neutron ray.

Kev thov ntawm PPS hauv 5G teb

1. FPC (lub rooj tsavxwm hloov tau yooj yim) yog ib qho yuav tsum muaj nyob rau hauv 5G kev lag luam mus ib txhis.

Flexible Circuit Court (FPC) yog lub tebchaws United States nyob rau xyoo 1970s rau kev txhim kho ntawm qhov chaw foob pob hluav taws kev tshawb fawb thiab kev loj hlob, los ntawm cov ntaub ntawv yooj yim nyias nyias, embedded Circuit Court tsim, thiaj li hais tias ib tug loj tus naj npawb ntawm precision Cheebtsam nyob rau hauv ib tug nqaim thiab txwv qhov chaw, thiaj li. los tsim ib lub voj voog hloov tau.

Liquid crystal polymer (LCP) zaj duab xis yog dav siv nyob rau hauv kev ua lag luam. Txawm li cas los xij, tus nqi siab thiab kev ua cov yam ntxwv ntawm LCP tseem yog ib qho teeb meem, yog li qhov tshwm sim ntawm cov khoom siv tshiab yog qhov kev xav tau ceev ntawm lub khw.

Toray tau tsom mus rau kev lag luam zoo thiab xav tau nrog nws cov cuab yeej siv thev naus laus zis los tsim biaxial stretched polyphenylene sulfide (PPS) zaj duab xis Torelina®. Nws muaj tib yam lossis zoo dua dielectric zog dua li LCP zaj duab xis.
