I-Polyphenylene Sulfide (PPS) - Ithuba elitsha le-5G

 

I-Polyphenylene sulfide (PPS)luhlobo lweplastiki yobunjineli ekhethekileyo ye-thermoplastic eneempawu ezilungileyo ezibanzi. Iimpawu zayo ezibalaseleyo kukumelana nokushisa okuphezulu, ukuxhathisa ukubola kunye neempawu eziphezulu zemishini.

I-PPS isetyenziswa kakhulu kwiimoto, zombane kunye ne-elektroniki, imboni yoomatshini, i-petrochemical industry, i-pharmaceutical industry, i-industry light, i-industry yempi, i-aerospace, i-5G yonxibelelwano kunye nezinye iindawo, yenye yezona zinto zisetyenziswa kakhulu kwiiplastiki zobunjineli ezizodwa.

 

Ngokufika kwexesha le-5G, i-PPS iye yanda kwakhona kule ntsimi evelayo.

I-5G isizukulwana sesihlanu sobuchwephesha bonxibelelwano lweselula, isantya sokuhambisa singaphezu kwe-100 amaxesha e-4G, ngoko ke izinto ze-5G zineemfuno eziphezulu kwi-dielectric constant.Ngokuqhelekileyo, imvume yempahla ye-resin ifuneka kuphela ukuba ibe ngaphantsi kwe-3.7 kwiimveliso ze-4G, ngelixa imvume ye-resin composite material ifunwa ngokubanzi ukuba ibe phakathi kwe-2.8 kunye ne-3.2 yeemveliso ze-5G.

Iimpawu zePPS

1. Iimpawu ze-Thermal

I-PPS inokumelana nobushushu obubalaseleyo, ngakumbi phantsi kokufuma okuphezulu kunye neemeko zoxinzelelo oluphezulu. Ibanga lokumelana nobushushu le-PPS lombane lifikelela ku-F (ibakala le-YAEBFH, inqanaba lokumelana nobushushu liyanyuka ngokulandelelana). Ifilimu ye-PPS ineyona nto iphezulu ye-flame retardant (ukuzicima) xa kungekho zongezelelo konke konke. Ifilimu ye-PPS engaphezulu kwe-25mm ichongwe njengemathiriyeli yodidi lwe-UL94 V0.

2. Iimpawu zoomatshini

Iipropathi zokuqina kunye neepropathi zokucutshungulwa kwefilimu ye-PPS ziyafana nezo ze-PET, kwaye ifilimu ye-PPS isenokugcina amandla aphezulu kunye nokuqina kwiqondo lobushushu eliphantsi le--196 ℃, elinokusetyenziswa njengezinto zokugquma ezinxulumene ne-superconductivity.

Ngaphezu koko, ukunyuswa kwexesha elide kunye nokufuma kwe-PPS kuphantsi kakhulu kunefilimu ye-PET, ngakumbi impembelelo yokufuma kwifilimu ye-PPS incinci kakhulu, ngoko ke uzinzo lwe-dimensional luhle kakhulu, olunokuthi luthathe indawo ye-PET njengendawo yokurekhoda. ukufota kunye nezinye izixhobo zefilimu ezisisiseko ezinxulumene nomfanekiso.

3. Iimpawu zeMichiza

I-PPS ixhathisa kwi-solvents ezininzi ze-organic, ukongeza kwi-asidi ye-sulfuric egxininisiweyo, ukufakwa kwe-nitric acid, kuphela kwi-2-chlornaphthalene, i-diphenyl ether kunye nezinye izinyibilikisi ezikhethekileyo ezingaphezu kwe-200 ℃ zaqala ukunyibilika.ukuchasana kwayo ngowesibini kuphela ukumkani yeplastiki PTFE.

4. Umbane

I-PPS ineempawu eziphezulu zombane, i-dielectric ihlala izinzile kakhulu kuluhlu olubanzi lobushushu kunye nokuphindaphinda, kwaye ilahleko ye-dielectric ye-Angle tangent incinci ngokwaneleyo ukuba ikhuphisane ne-polypropylene. Njenge-capacitor dielectric, i-capacitance yayo inokuxhomekeka okuncinci kwiqondo lokushisa kunye nokuphindaphinda, ngoko ke ilahleko ephantsi ye-capacitor inokufumaneka.

5. Okunye ukusebenza

Ukuxinana komphezulu wefilimu ye-PPS ingaphantsi kancinane kunefilimu ye-PET, kodwa ikwafanelekile ukusetyenzwa kwengubo. Kwiimeko apho i-adhesive isetyenziswe kunye nezinye i-laminates zefilimu, umphezulu kufuneka uphathwe nge-corona ukwandisa ukunyanzeliswa komphezulu kwi-58d / cm.

Uburhabaxa bomphezulu kunye ne-friction coefficient yefilimu ye-PPS inokulungelelaniswa ngokwenjongo efana ne-PET. I-PPS inwebu yenye yeenwebu ezimbalwa zezinto eziphilayo ezinokuthi zisetyenziswe kumda wereactor yenyukliya kunye neziko lokudibanisa ngenxa yokuqina kwayo okuphezulu ngokuchasene ne-r ray kunye ne-neutron ray.

Isakhono sefilimu yePPS

 

Ukusetyenziswa kwePPS kwintsimi ye-5G

1. I-FPC (ibhodi yesekethe eguquguqukayo) kufuneka ibe nayo kwishishini le-5G ngonaphakade.

Isekethe eguquguqukayo (FPC) yi-United States kwiminyaka yoo-1970 yophuhliso lophando lwe-rocket kunye nophuhliso, ngokusebenzisa iphepha leplastiki elithambileyo elithambileyo, uyilo lwesekethe edibeneyo, ukuze inani elikhulu lamacandelo achanekileyo kwindawo emxinwa kunye nencinci, ukuze ukwenza isekethe eguquguqukayo.

Ifilimu ye-Liquid crystal polymer (LCP) isetyenziswa ngokubanzi kwimarike. Nangona kunjalo, ixabiso eliphezulu kunye neempawu zokucubungula i-LCP ziseyingxaki, ngoko ke ukuvela kwezinto ezintsha kuyimfuno engxamisekileyo yemarike.

I-Toray ijolise ngokufanelekileyo kwintengiso kunye nemfuno ngetekhnoloji yayo yokusika ukwenza ifilimu ye-biaxial eyoluliweyo ye-polyphenylene sulfide (PPS) iTorelina®. Ineempawu ezifanayo okanye ezingcono zedielectric kunefilimu yeLCP.
