Polyphenylene Sulfide (PPS) - Mukana Mutsva we5G

 

Polyphenylene sulfide (PPS)imhando ye thermoplastic yakakosha engineering plastiki ine yakanaka yakazara zvivakwa. Hunhu hwayo hwakatanhamara ndeyekupisa tembiricha kuramba, corrosion resistance uye yepamusoro ma mechanical properties.

PPS inoshandiswa zvakanyanya mumotokari, magetsi nemagetsi, indasitiri yemichina, indasitiri yepetrochemical, indasitiri yemishonga, indasitiri yemwenje, indasitiri yemauto, aerospace, 5G kutaurirana nemamwe minda, ndeimwe yeanonyanya kushandiswa akakosha einjiniya mapurasitiki.

 

Nekuuya kweiyo 5G era, PPS yakawedzerawo mundima iri kubuda.

5G chizvarwa chechishanu chekombiyuta yekukurukurirana kwefoni, kukurumidza kwekufambisa kunopfuura ka100 nguva ye4G, saka 5G zvinhu zvine zvinodiwa zvakanyanya pa dielectric constant.Kazhinji, kubvumidzwa kweiyo resin zvinhu kunongodiwa kuve pazasi 3.7 kune zvigadzirwa zve4G, nepo kubvumidzwa kweiyo resin inoumbwa zvinhu kunowanzo kudiwa kuve pakati pe2.8 uye 3.2 ye5G zvigadzirwa.

Maitiro ePPS

1. Thermal properties

PPS ine yakatanhamara yekudzivirira kupisa, kunyanya pasi pehunyoro hwakanyanya uye yakanyanya kushushikana mamiriro. PPS yemagetsi ekudzivirira kupisa giredhi inosvika F (YAEBFH giredhi, kupisa kwekudzivirira giredhi kunowedzera mukutendeuka). Firimu rePPS rine yakanyanya kudzima moto (kuzvidzima) kana pasina zvinowedzerwa zvachose. PPS firimu pamusoro pe25mm inozivikanwa seUL94 V0 giredhi zvinhu.

2. Mechanical maitiro

Izvo zvinorema zvivakwa uye kugadzirisa zvimiro zvePPS firimu zvakafanana neaya ePET, uye firimu rePPS rinogona kuramba richichengetedza simba rakawanda uye kuomarara pakudzikira kwakadzika kwe -196 ℃, inogona kushandiswa sechinhu chekudzivirira chine chekuita ne superconductivity.

Uyezve, kunyura kwenguva refu uye kunyura kwehunyoro kwePPS kwakadzikira kupfuura iyo yePET firimu, kunyanya mhedzisiro yekunyorova paPPS firimu idiki kwazvo, saka kugadzikana kwedimensional kwakanaka kwazvo, kunogona kutsiva PET senge rekodhi rekodhi repakati, mafoto uye zvimwe zvine chekuita nemifananidzo zvigadziriso zvemufirimu.

3. Chemical properties

PPS inoshingirira kune yakawanda organic solvents, kuwedzera kune concentrated sulfuric acid, yakadzika nitric acid impregnation, chete mu2-chlornaphthalene, diphenyl ether uye zvimwe zvakakosha zvinonyungudutsa pamusoro pe200 ℃ zvakangotanga kunyungudika,kushorwa kwayo ndeyechipiri chete kune mambo epurasitiki PTFE.

4. Zvemagetsi

PPS ine yakakwira frequency maitiro emagetsi, iyo dielectric kugara yakagadzikana zvakanyanya muhupamhi hwekushisa uye frequency, uye kurasikirwa kwayo kwedielectric Angle tangent idiki zvakakwana kukwikwidza polypropylene. Sezvo capacitor dielectric, capacitance yayo haina kutsamira pane tembiricha uye frequency, saka yakaderera kurasikirwa capacitor inogona kuwanikwa.

5. Kumwe kuita

Iko kushushikana kwepamusoro kwePPS firimu kwakadzikira zvishoma pane iyo yePET firimu, asi inokodzerawo kurongedza. Muzviitiko apo kunamira kunoshandiswa nemamwe firimu laminates, iyo yepamusoro inofanirwa kugadziriswa korona kuti iwedzere tension yepasi kusvika 58d/cm.

Iyo hutsinye hwepamusoro uye friction coefficient yePPS firimu inogona kugadziriswa zvinoenderana nechinangwa sePET. PPS membrane ndeimwe yeashoma organic membranes anogona kushandiswa kunharaunda yenyukireya reactor uye fusion choto nekuda kwekusimba kwayo kwepamusoro kurwisa r ray uye neutron ray.

Kushandiswa kwePPS mundima ye5G

1. FPC (flexible circuit board) inofanirwa-iine mumabhizimisi e5G nokusingaperi.

Flexible circuit (FPC) iUnited States mu1970s yekuvandudza nzvimbo yekutsvagisa uye kusimudzira, kuburikidza neinochinjika pepa repurasitiki rakatetepa, rakamisikidzwa redunhu dhizaini, kuitira kuti huwandu hukuru hwezvinhu chaizvo munzvimbo yakamanikana uye shoma, kuitira kugadzira dunhu rinochinjika.

Liquid crystal polymer (LCP) firimu rinoshandiswa zvakanyanya mumusika. Nekudaro, iyo yakakwira mutengo uye maitiro ekugadzirisa eLCP ichiri dambudziko, saka kubuda kwechinhu chitsva ndiko kudiwa kwekukurumidzira kwemusika.

Toray yakanyatso kunanga musika uye kudiwa neayo ekucheka-kumucheto tekinoroji kugadzira biaxial yakatambanudzwa polyphenylene sulfide (PPS) firimu Torelina®. Iyo ine zvakafanana kana zvirinani dielectric zvivakwa kupfuura LCP firimu.
