Polyphenylene Sulfide (PPS) - Amahirwe mashya ya 5G

 

Polyphenylene sulfide (PPS)ni ubwoko bwa thermoplastique idasanzwe yububiko bwa plastike hamwe nibintu byiza byuzuye.Ibintu byingenzi biranga ni ubushyuhe bwo hejuru, kurwanya ruswa hamwe nubukanishi buhebuje.

PPS ikoreshwa cyane mu binyabiziga, amashanyarazi na elegitoronike, inganda z’imashini, inganda za peteroli, inganda zikora imiti, inganda zoroheje, inganda za gisirikare, icyogajuru, itumanaho rya 5G n’izindi nzego, ni imwe mu mashanyarazi yihariye akoreshwa cyane.

 

Hamwe nigihe cya 5G, PPS nayo yagutse muriki gice kigaragara.

5G ni igisekuru cya gatanu cyikoranabuhanga ryitumanaho rigendanwa, umuvuduko wo kohereza wikubye inshuro zirenga 100 urwa 4G, bityo ibikoresho 5G bifite ibisabwa byinshi kuri dielectric ihoraho.Mubisanzwe, uruhushya rwibikoresho bya resin rusabwa gusa kuba munsi ya 3.7 kubicuruzwa bya 4G, mugihe uruhushya rwibikoresho bya resin rusanzwe rusabwa kuba hagati ya 2.8 na 3.2 kubicuruzwa 5G. 

Kugereranya kwa dielectric constants

Ibiranga PPS

1. Ibikoresho byubushyuhe

PPS ifite ubushyuhe budasanzwe bwo kurwanya ubushyuhe, cyane cyane mu gihe cy'ubushyuhe bwinshi no mu bihe byinshi.PPS amashanyarazi yubushyuhe bwo kurwanya ubushyuhe bugera kuri F (icyiciro cya YAEBFH, igipimo cyo kurwanya ubushyuhe cyiyongera muburyo).Filime ya PPS ifite flame retardant (kwiyizimya) mugihe nta nyongeramusaruro namba.Filime ya PPS irenga 25mm izwi nkibikoresho bya UL94 V0.

2. Ibiranga imashini

Imiterere ya tensile hamwe nuburyo bwo gutunganya firime ya PPS isa nkiya PET, kandi firime ya PPS irashobora gukomeza imbaraga nyinshi nubukomere ku bushyuhe buke bwa -196 ℃, bushobora gukoreshwa nkibikoresho byo kubika ibintu bijyanye na superconductivity.

Byongeye kandi, igihe kirekire cyinjira hamwe nubushuhe bwa PPS biri hasi cyane ugereranije nibya firime ya PET, cyane cyane ingaruka zubushuhe kuri firime ya PPS ni nto cyane, kuburyo guhagarara neza ari byiza cyane, bishobora gusimbuza PET nkibikoresho byo gufata amajwi, gufotora nibindi bikoresho bifitanye isano n'amashusho ibikoresho bya firime.

3. Imiterere yimiti

PPS irwanya ibishishwa byinshi kama, usibye acide sulfurike yibanze, kwinjiza aside nitricike, gusa muri 2-chlornaphthalene, diphenyl ether hamwe nindi mashanyarazi idasanzwe iri hejuru ya 200 ℃ yatangiye gushonga,kurwanya kwayo ni kumwanya wa kabiri nyuma yumwami wa plastike PTFE.

4. Amashanyarazi

PPS ifite amashanyarazi menshi aranga amashanyarazi, ihoraho ya dielectric ihagaze neza cyane mubushyuhe bwinshi nubushyuhe, kandi gutakaza dielectric Angle tangent ni nto bihagije kugirango ihangane na polypropilene.Nka capacitor dielectric, ubushobozi bwayo ntabwo bushingiye cyane kubushyuhe ninshuro, bityo ubushobozi buke bushobora kuboneka.

 

Ubushobozi bwa PPS

5. Ibindi bikorwa

Ubuso bwubuso bwa firime ya PPS buri munsi gato ugereranije na firime ya PET, ariko kandi irakwiriye no gutunganya.Mugihe aho ifatizo ikoreshwa hamwe nizindi firime ya laminate, ubuso bugomba gufatwa na corona kugirango byongere ubushyuhe kuri 58d / cm.

Ubuso bwo hejuru hamwe na coefficient ya friction ya firime ya PPS irashobora guhinduka ukurikije intego kimwe na PET.PPS membrane nimwe mumyanya mike ishobora gukoreshwa mugace ka reaction ya nucleaire hamwe nitanura rya fusion kubera ko iramba cyane irwanya imirasire ya rayon na neutron.

Ubushobozi bwa firime ya PPS

 

Ikoreshwa rya PPS mumurima wa 5G

1. FPC (flexible circuit board) igomba-kugira inganda 5G ubuziraherezo.

Inzira zoroshye (FPC) ni Reta zunzubumwe zamerika mu myaka ya za 70 kugirango iteze imbere ubushakashatsi n’iterambere rya roketi yo mu kirere, ibinyujije mu rupapuro rworoshye rwa pulasitike rworoshye, rwashushanyijeho uruziga, ku buryo umubare munini w’ibice byuzuye mu mwanya muto kandi muto, ku buryo gukora uruziga rworoshye.

Filime ya kirisiti ya polymer (LCP) ikoreshwa cyane kumasoko.Nyamara, igiciro kinini no gutunganya ibiranga LCP biracyari ikibazo, bityo kugaragara kwibintu bishya nibyo byihutirwa isoko.

Toray yibasiye cyane isoko kandi isaba ikorana buhanga rigezweho kugirango ikore biaxial irambuye ya polifenile sulfide (PPS) film Torelina®.Ifite imiterere ya dielectric imwe cyangwa nziza kuruta firime ya LCP.

Torelina ® gusaba

Ibikoresho byo gukwirakwiza amashanyarazi (moteri / transformateur / wire)

Ibikoresho bya elegitoronike (bateri ya lithium / capacitor)

Ubwubatsi buke bwa firime (ibikoresho by'amashanyarazi)
