Kugawika kwa Kutentha Kwapamwamba kwa Nylon PA ndi Kugwiritsa Ntchito Kwake mu Electronic Field

Nayiloni yotentha kwambiri (HTPA)ndi pulasitiki yapadera ya nayiloni yomwe ingagwiritsidwe ntchito m'malo a 150 ℃ kapena kupitirirapo kwa nthawi yayitali. Malo osungunuka nthawi zambiri ndi 290 ℃ ~ 320 ℃, ndipo kutentha kwa kutentha kumatha kufika 290 ℃ pambuyo pa kusinthidwa kwa galasi la galasi, ndikukhalabe ndi makina abwino kwambiri pa kutentha kwakukulu ndi chilengedwe cha chinyezi.

Ndi ntchito yake yabwino kwambiri, zida za nayiloni zotentha kwambiri zimagwiritsidwa ntchito kwambiri pamagetsi ogula monga ma laputopu ndi mafoni am'manja.

Gulu la nayiloni yotentha kwambiri

(1)Anayiloni ya liphatic PA46

Poyerekeza ndi pulasitiki wamba waukadaulo wa PA66, PA46 ili ndi masinthidwe apamwamba a mamolekyu komanso kusasinthasintha, kotero imakhala ndi kukana kutentha kwakukulu, mphamvu, kupindika modulus ndi kukhazikika kwazithunzi. Chifukwa cha crystallinity yayikulu ya PA46, liwiro lopanga limakhala lachangu kwambiri. PA46 imagwiritsidwa ntchito kwambiri pamagetsi, zakuthambo, zamagalimoto, ndi zina zambiri.

DSM 30% galasi CHIKWANGWANI analimbitsa PA46 kwa mapanelo injini ndege

DSM 40% magalasi CHIKWANGWANI cholimbitsa PA46 pazambiri zamagalimoto

(2)Half onunkhira nayiloni - PPA

Thermal deformation kutentha kwa theka-onunkhira nayiloni ndi pakati pa 280 ℃ ndi 290 ℃. Mitundu yayikulu ndi PA4T, PA6T, PA9T, PA10T, ndi zina. Poyerekeza ndi PA66 wamba, PPA mayamwidwe amadzi ndi otsika kwambiri, ndipo kukana kwamafuta, kukhazikika kwa mawonekedwe ndi kukana kwanyengo ndizabwino kwambiri, zomwe zimagwiritsidwa ntchito nthawi zambiri pamagalimoto, zamagetsi zamagetsi, zamakina. , minda yazinthu.

Cholumikizira

(3) Nayiloni yonunkhira - PARA

PARA inapangidwa ndi DuPont, otchuka kwambiri omwe ndi Nomex (aramid 1313) ndi Kevlar (aramid 1414). Mtundu uwu wa zinthu makamaka ntchito yokonza CHIKWANGWANI mkulu ntchito ndi pepala, CHIKWANGWANI zopangidwa ndi mphamvu mkulu, mkulu okhwima, modulus mkulu, kutentha kukana, mkulu dielectric mphamvu makhalidwe. Itha kugwiritsidwa ntchito ngati ulusi wamphamvu kwambiri komanso zida zolimbikitsira zankhondo, zakuthambo ndi zida zina zamapangidwe.

Zida zankhondo za Aramid 1414

Kugwiritsa ntchito nayiloni yotentha kwambiri pamagetsi

(1) Foni yam'manja

Nayiloni yotentha kwambiri imagwiritsidwa ntchito kwambiri m'mafoni am'manja, monga chimango cha foni yam'manja, mlongoti, gawo la kamera, bulaketi yolankhulira, cholumikizira cha USB ndi zina zotero.

▶ Mlongoti wa foni yam'manja

Laser Direct prototyping (LDS) itha kugwiritsidwa ntchito mu tinyanga ta m'manja, mabwalo amagetsi apagalimoto, ma casings amakina opangira ndalama komanso Edzi yomva zachipatala. Chodziwika kwambiri ndi mlongoti wa foni yam'manja. LDS imatha laser antenna mwachindunji pa chipolopolo cha foni yam'manja, chomwe sichimangopewa kusokoneza chitsulo chamkati cha foni yam'manja, komanso chimachepetsa kukula kwa foni yam'manja.

Mapangidwe amitundu yambiri ya 5G antenna ya smartphone ndizovuta kwambiri, pamene mlongoti wa LDS umakumana ndi mapangidwe a mawonekedwe opyapyala ndi ochepetsetsa okhala ndi ufulu wapamwamba. PPA, monga chida cha LDS cha antenna, ili ndi makina abwino kwambiri komanso kukhazikika kwa mawonekedwe, kukana kutentha kwambiri, kusachita thovu komanso kutsika pang'ono pambuyo pakuwotcherera popanda lead, komanso kutayika kwa ma wayilesi otsika.

▶ Kapangidwe ka foni yam'manja

Chifukwa cha zovuta za ma radio frequency ma siginecha mu mafoni a m'manja a 5G, kugwiritsa ntchito ukadaulo wa nano-injection molding wafika pamlingo watsopano. Zida zomangira jekeseni wa nano zimafunika kupirira kutentha kwambiri, ndipo PPA ndi chimodzi mwazinthu zomwe zimakwaniritsa izi, ndipo PPA ili ndi makina abwino kwambiri komanso mphamvu yabwino yomangirira ndi zitsulo.

PPA imagwiritsidwa ntchito pazinthu zama foni zam'manja

▶ Cholumikizira cha USB

Kufunika kwa ntchito yothamangitsa mwachangu komanso kuyitanitsa mafoni a 5G opanda zingwe kwakweza zofunikira zachitetezo cha cholumikizira cha USB-C, ndipo kuyika kwa cholumikizira cha USB kumatengera ukadaulo wa SMT. Chifukwa cha mawonekedwe othamanga kwambiri a cholumikizira ndi zosowa zaukadaulo wopanga ndi kuyika, zida zolimbana ndi kutentha kwambiri zakhala zofunikira. PPA ili ndi mawonekedwe a kukana kutentha kwambiri komanso osasintha. Amagwiritsidwa ntchito kwambiri mu foni yam'manja USB.

(2) Malaputopu ndi mapiritsi

Nayiloni yotentha kwambiri imatha m'malo mwachitsulo kuti ikwaniritse kapangidwe kakang'ono, ingagwiritsidwe ntchito ngati cholembera, chipolopolo chathyathyathya, kukana kutentha kwambiri komanso kukhazikika kwapakatikati kumapangitsa kuti igwiritsidwe ntchito kwambiri mu fan, mawonekedwe a cholembera. 

Chivundikiro cha kompyuta laputopu

(3) Zovala mwanzeru

Nayiloni yotentha kwambiri imatha kugwiritsidwanso ntchito pamayendedwe a LDS stereo ya wotchi yanzeru, mlongoti wa laser engraving, kesi, chithandizo chamkati ndi chipolopolo chakumbuyo ndi zinthu zina.

Kugwiritsa ntchito nayiloni kutentha kwambiri mu smartwatch
