I-Polyphenylene Sulfide (PPS) – Ithuba Elisha le-5G

 

I-Polyphenylene sulfide (PPS)iwuhlobo lwepulasitiki ekhethekile yobunjiniyela be-thermoplastic enezakhiwo ezinhle ezibanzi. Izici zayo ezivelele ukumelana nokushisa okuphezulu, ukumelana nokugqwala kanye nezakhiwo eziphakeme zemishini.

I-PPS isetshenziswa kabanzi embonini yezimoto, kagesi neye-elekthronikhi, embonini yemishini, embonini ye-petrochemical, embonini yezemithi, imboni yokukhanya, imboni yezempi, i-aerospace, ukuxhumana kwe-5G neminye imikhakha, ingenye yepulasitiki ekhethekile yobunjiniyela esetshenziswa kakhulu.

 

Ngokufika kwenkathi ye-5G, i-PPS iphinde yanda kulo mkhakha osafufusa.

I-5G iyisizukulwane sesihlanu sobuchwepheshe bokuxhumana kweselula, isivinini sokudlulisa singaphezu kwezikhathi ze-100 kune-4G, ngakho-ke izinto ze-5G zinezidingo eziphezulu ku-dielectric constant.Ngokuvamile, imvume yezinto ze-resin idingeka kuphela ukuthi ibe ngaphansi kuka-3.7 emikhiqizweni ye-4G, kuyilapho imvume yezinto ezihlanganisiwe ze-resin ngokuvamile idingeka ukuthi ibe phakathi kuka-2.8 no-3.2 emikhiqizweni ye-5G.

Izimpawu ze-PPS

1. Izakhiwo ezishisayo

I-PPS inokumelana nokushisa okuvelele, ikakhulukazi ngaphansi komswakama ophezulu nezimo zengcindezi ephezulu. Ibanga lokumelana nokushisa likagesi le-PPS lifinyelela ku-F (ibanga le-YAEBFH, izinga lokumelana nokushisa liyakhuphuka ngokushintshana). Ifilimu ye-PPS ine-flame retardant ephezulu kakhulu (eyazicishayo) uma zingekho nhlobo izithasiselo. Ifilimu ye-PPS engaphezu kuka-25mm ikhonjwa njengezinto zebanga le-UL94 V0.

2. Izici zemishini

Izakhiwo eziqinile kanye nezakhiwo zokucubungula zefilimu ye-PPS ziyefana nalezo ze-PET, futhi ifilimu ye-PPS isengakwazi ukugcina amandla aphezulu kanye nokuqina ekushiseni okuphansi okungu- -196 ℃, okungasetshenziswa njengezinto zokufakelwa ezihlobene ne-superconductivity.

Ngaphezu kwalokho, ukumunca isikhathi eside nokumuncwa komswakama kwe-PPS kuphansi kakhulu kunefilimu ye-PET, ikakhulukazi umphumela womswakama kufilimu ye-PPS mncane kakhulu, ngakho-ke ukuzinza kwe-dimensional kuhle kakhulu, okungangena esikhundleni se-PET njengendawo yokurekhoda kazibuthe, izithombe nezinye izinto eziyisisekelo zefilimu eziyisisekelo.

3. Izakhiwo zamakhemikhali

I-PPS imelana nezinyibilikisi eziningi eziphilayo, ngaphezu kwe-sulfuric acid egxilile, ukufakwa kwe-nitric acid egxilile, kuphela ku-2-chlornaphthalene, i-diphenyl ether nezinye izincibilikisi ezikhethekile ezingaphezu kuka-200 ℃ kuphela zaqala ukuncibilika,ukumelana kwayo kungokwesibili kuphela kwenkosi yepulasitiki i-PTFE.

4. Ezogesi

I-PPS inezici zikagesi ezivama kakhulu, i-dielectric engaguquki izinzile ngokwedlulele ebangeni elibanzi lokushisa nemvamisa, futhi ukulahleka kwayo kwe-dielectric I-Angle tangent incane ngokwanele ukuze ilingane ne-polypropylene. Njenge-capacitor dielectric, i-capacitance yayo inokuncika okuncane ekushiseni kanye nemvamisa, ngakho-ke i-capacitor yokulahlekelwa ephansi ingatholakala.

5. Okunye ukusebenza

Ukungezwani okungaphezulu kwefilimu ye-PPS kuphansi kancane kunefilimu ye-PET, kodwa futhi ilungele ukucutshungulwa kokumbozwa. Ezimeni lapho okunamathelayo kusetshenziswa namanye ama-laminates efilimu, indawo engaphezulu kufanele iphathwe nge-corona ukuze kwandiswe ukungezwani kwendawo kufinyelele ku-58d/cm.

Ubulukhuni obungaphezulu kanye ne-friction coefficient yefilimu ye-PPS ingalungiswa ngokuya nenjongo njenge-PET. Ulwelwesi lwe-PPS lungenye yezingqimba ezimbalwa zezinto eziphilayo ezingasetshenziswa endaweni ezungezile ye-nuclear reactor kanye ne-fusion furnace ngenxa yokuqina kwayo okuphezulu ngokumelene ne-r ray kanye ne-neutron ray.

Ukusetshenziswa kwe-PPS emkhakheni we-5G

1. I-FPC (ibhodi lesifunda eliguquguqukayo) kufanele ube nayo embonini ye-5G kuze kube phakade.

I-Flexible circuit (FPC) yi-United States ngeminyaka yawo-1970 ukuze kuthuthukiswe ucwaningo lwerokhethi yasemkhathini kanye nokuthuthukiswa, ngokusebenzisa ishidi lepulasitiki elithambile elithambile, umklamo wesekethe oshunyekiwe, ukuze inani elikhulu lezingxenye ezinembayo endaweni encane futhi enomkhawulo, ukuze ukwakha isifunda esivumelana nezimo.

Ifilimu ye-Liquid crystal polymer (LCP) isetshenziswa kabanzi emakethe. Kodwa-ke, izindleko eziphakeme kanye nezici zokucubungula ze-LCP ziseyinkinga, ngakho-ke ukuvela kwezinto ezintsha kuyisidingo esiphuthumayo semakethe.

I-Toray iqondise ngempumelelo imakethe kanye nesidingo ngobuchwepheshe bayo obusezingeni eliphezulu ukwenza ifilimu ye-biaxial stretched polyphenylene sulfide (PPS) i-Torelina®. Inezici ezifanayo noma ezingcono kakhulu ze-dielectric kunefilimu ye-LCP.
