Amapulasitiki obunjiniyela amelana nokushisa i-PPA-GF, FR ye-breaker nama-bobbins

Incazelo emfushane:

I-PPA yepulasitiki ebonakalayo inamandla futhi ilukhuni kune-polyamides njengenayiloni6, kanye nama-66, njll.Ukuzwela okuphansi kwamanzi;Ukusebenza okungcono kokushisayo;Futhi ukukhasa, ukukhathala nokumelana namakhemikhali kungcono kakhulu.

Omaka bomkhiqizo

I-Polyphthalamide (aka. PPA, High Performance Polyamide) isethi engaphansi yezinhlaka zokwenziwa ze-thermoplastic emndenini we-polyamide (inayiloni) echazwa ngokuthi lapho ama-moles angu-55% noma ngaphezulu engxenye ye-carboxylic acid yeyunithi ephindayo ochungechungeni lwe-polymer yakhiwe inhlanganisela. i-terephthalic (TPA) kanye ne-isophthalic (IPA) acids. Ukushintshwa kwe-aliphatic kunquma ngezinqumo ezinephunga elimnandi kumgogodla we-polymer kwandisa indawo yokuncibilika, izinga lokushisa lokushintsha kwengilazi, ukumelana namakhemikhali nokuqina.

Ama-resins asekelwe e-PPA abunjwa abe izingxenye ukuze athathe indawo yensimbi ezinhlelweni ezidinga ukumelana nezinga lokushisa eliphezulu njengezingxenye zesitimela samandla ezimoto, indawo yokuhlala yezixhumi zikagesi ezishisayo nezinye izinto eziningi ezisetshenziswayo.

Izinga lokushisa lengilazi le-PPA liyakhuphuka njengoba inani le-TPA likhuphuka. Uma ngaphezu kwama-55% engxenye ye-asidi ye-PPA yenziwe nge-IPA, khona-ke i-copolymer i-amorphous. Izakhiwo zama-semi crystalline polymers v amorphous polymers zichazwe kwenye indawo ngokuningiliziwe. Kafushane, i-crystalline isiza ngokumelana namakhemikhali kanye nezakhiwo zemishini ngaphezu kwezinga lokushisa lokushintsha kwengilazi (kodwa ngaphansi kwendawo yokuncibilika). Ama-polymers angama-amorphous mahle ku-warpage nasekukhanyeni.

Izici ze-PPA

Impahla ye-PPA inezakhiwo ezinhle kakhulu zokuhlanganisa, ezisebenza kahle ezindaweni ezishisayo, zikagesi, ezingokwenyama namakhemikhali. Ikakhulukazi ngaphansi kwezinga lokushisa eliphezulu i-PPA isenokuqina okuphezulu namandla aphezulu, kanye nokunemba okuhle kakhulu kwe-dimensional nokuzinza.

Inkambu Yesicelo Eyinhloko ye-PPA

Okukhethekile ukusetshenziswa kwebanga lokuhlangana kokulawula izinga lokushisa lamanzi ezimoto kanye nengxenye yomzimba ye-thermostat.
