Polyphenylene Sulfide (PPS) - Mwayi Watsopano wa 5G

 Mwayi1

Polyphenylene sulfide (PPS)ndi mtundu wa pulasitiki wapadera wa thermoplastic wokhala ndi katundu wabwino wokwanira. Makhalidwe ake apamwamba ndi kukana kutentha kwambiri, kukana kwa dzimbiri komanso makina apamwamba kwambiri.

PPS chimagwiritsidwa ntchito magalimoto, magetsi ndi zamagetsi, makampani makina, makampani petrochemical, makampani mankhwala, makampani kuwala, makampani asilikali, Azamlengalenga, 5G kulankhulana ndi madera ena, ndi mmodzi wa ambiri ankagwiritsa ntchito mwapadera uinjiniya mapulasitiki.

Kubwera kwa nthawi ya 5G, PPS yakulanso kumunda womwe ukubwerawu.

5G ndi mbadwo wachisanu wa teknoloji yolankhulana ndi mafoni, liwiro la kutumizira ndiloposa 100 nthawi ya 4G, kotero zipangizo za 5G zimakhala ndi zofunikira kwambiri pa dielectric constant.Nthawi zambiri, kuloledwa kwa zinthu za utomoni kumangofunika kukhala pansi pa 3.7 pazogulitsa za 4G, pomwe kuloledwa kwa zinthu zophatikizika za utomoni kumafunika kukhala pakati pa 2.8 ndi 3.2 pazogulitsa za 5G.

Zithunzi za PPS

1. Thermal katundu

PPS ili ndi kukana kutentha kwapadera, makamaka pansi pa chinyezi chambiri komanso kupsinjika kwakukulu. PPS magetsi kutchinjiriza kutentha kukana kalasi ifika F (YAEBFH kalasi, kutentha kukana kalasi kumawonjezeka motsatira). Kanema wa PPS ali ndi chotchingira moto kwambiri (chozimitsa chokha) pomwe palibe zowonjezera. Kanema wa PPS wopitilira 25mm amadziwika kuti ndi zinthu zamakalasi a UL94 V0.

2. Makhalidwe amakina

Zomwe zimakokedwa komanso kukonzanso kwa filimu ya PPS ndizofanana ndi za PET, ndipo filimu ya PPS imatha kukhalabe ndi mphamvu komanso kulimba pa kutentha kochepa kwa -196 ℃, komwe kungagwiritsidwe ntchito ngati zinthu zotchinjiriza zokhudzana ndi superconductivity.

Komanso, kukwawa kwa nthawi yayitali komanso kuyamwa kwa chinyezi kwa PPS ndikotsika kwambiri kuposa filimu ya PET, makamaka mphamvu ya chinyezi pafilimu ya PPS ndi yaying'ono kwambiri, kotero kukhazikika kwa mawonekedwe ndikwabwino kwambiri, komwe kungalowe m'malo mwa PET ngati sing'anga yojambulira maginito, kujambula ndi zinthu zina zoyambira mafilimu okhudzana ndi zithunzi.

3. Mankhwala katundu

PPS kugonjetsedwa ndi zosungunulira zambiri organic, kuwonjezera anaikira sulfuric asidi, anaikira nitric asidi impregnation, kokha mu 2-chlornaphthalene, diphenyl efa ndi zosungunulira zina zapadera pamwamba 200 ℃ anayamba kupasuka,kukana kwake ndi kwachiwiri kwa mfumu ya pulasitiki PTFE.

4. Zamagetsi

PPS ili ndi mawonekedwe amagetsi apamwamba kwambiri, dielectric yake imakhala yokhazikika pamitundu yosiyanasiyana ya kutentha ndi ma frequency, ndipo kutayika kwake kwa dielectric Angle tangent ndi yaying'ono yokwanira kulimbana ndi polypropylene. Monga capacitor dielectric, mphamvu yake imadalira pang'ono kutentha ndi mafupipafupi, kotero kuti capacitor yotsika kwambiri ingapezeke.

5. Ntchito zina

Kuvuta kwa filimu ya PPS ndikotsika pang'ono poyerekeza ndi filimu ya PET, koma ndiyoyeneranso kupaka utoto. Ngati zomatira zimagwiritsidwa ntchito ndi zomata zina zamakanema, pamwamba pake ziyenera kupakidwa ndi corona kuti ziwonjezeke kumtunda kwa 58d/cm.

Kukula kwamphamvu komanso kukangana kwa filimu ya PPS kumatha kusinthidwa malinga ndi cholinga monga PET. PPS membrane ndi imodzi mwazinthu zochepa zomwe zitha kugwiritsidwa ntchito m'mphepete mwa nyukiliya ya nyukiliya komanso ng'anjo yophatikizika chifukwa cha kulimba kwake motsutsana ndi ray ndi neutron ray.

Kugwiritsa ntchito PPS mu gawo la 5G

1. FPC (bodi losinthasintha) ndilofunika kukhala nalo mu makampani a 5G kwamuyaya.

Flexible circuit (FPC) ndi United States m'zaka za m'ma 1970 pakupanga kafukufuku wa rocket ndi chitukuko, kupyolera mu pepala la pulasitiki losinthika lopyapyala, kapangidwe ka dera lophatikizidwa, kotero kuti chiwerengero chachikulu cha zigawo zolondola mu malo opapatiza komanso ochepa. kupanga chigawo chosinthika.

Kanema wa Liquid crystal polymer (LCP) amagwiritsidwa ntchito kwambiri pamsika. Komabe, kukwera mtengo komanso mawonekedwe a LCP akadali vuto, chifukwa chake kuwonekera kwazinthu zatsopano ndikofunikira kwambiri pamsika.

Toray yalunjika pamsika ndikufunidwa ndiukadaulo wake wapamwamba kwambiri wopanga filimu ya biaxial stretched polyphenylene sulfide (PPS) Torelina®. Ili ndi zinthu zofanana kapena zabwinoko za dielectric kuposa filimu ya LCP.

Ubwino mu FPC

Zida zokhala ndi kutayika kwa dielectric otsika pama frequency apamwamba.

Kutaya kufalikira kokhazikika pansi pa kutentha kwakukulu ndi chinyezi.

M'magalimoto, mafakitale amagetsi akhala akupanga zinthu zambiri.

Mayamwidwe otsika amadzi & kukana hydrolysis.

Ndi njira yabwino kwambiri yosinthira LCP & MPI (Modified polyimide).

2. Pulasitiki mlongoti oscillator

Zomwe zimatchedwa mlongoti oscillator ndi chabe chidutswa chachitsulo chowongolera chomwe chimatumiza ndi kulandira zizindikiro zothamanga kwambiri. Iyi ndiye mlongoti wa 4G, ndipo mlongoti wa 5G udzakhala wocheperako. 

Mwayi12

Traditional mlongoti vibrator ntchito zinthu ndi zitsulo kapena PC bolodi, pambuyo 5 g nyengo, monga kufunika apamwamba kulankhulana, chiwerengero cha vibrator adzawonjezeka kwambiri, ngati ntchito zipangizo zitsulo, akhoza kulola mlongoti kukhala wolemera kwambiri, mtengo ndi okwera mtengo kwambiri, kotero mu mapangidwe a 5 g mlongoti oscillator ndiye kusankha kwa mapulasitiki opangira kutentha kwambiri.
