Polyphthalamide (aka. PPA, High Performance Polyamide) ndi kagawo ka thermoplastic synthetic resins mu banja la polyamide (nayiloni) yomwe imatanthauzidwa ngati 55% kapena ma moles a carboxylic acid gawo la gawo lobwereza mu tcheni cha polima limapangidwa ndi kuphatikiza. terphthalic (TPA) ndi isophthalic (IPA) zidulo.M'malo mwa aliphatic amasankha ndi onunkhira amasankha mu polima msana kumawonjezera malo osungunuka, kutentha kwa galasi, kukana mankhwala ndi kuuma.

Ma resins opangidwa ndi PPA amapangidwa kukhala magawo kuti alowe m'malo mwazitsulo pamagwiritsidwe omwe amafunikira kukana kutentha kwambiri monga zida zamagalimoto zamagalimoto, nyumba zolumikizira magetsi otentha kwambiri ndi ntchito zina zambiri.

Kutentha kwa kusintha kwa galasi kwa PPA kumawonjezeka pamene kuchuluka kwa TPA kumawonjezeka.Ngati kupitirira 55% ya gawo la asidi la PPA lapangidwa kuchokera ku IPA, ndiye kuti copolymer ndi amorphous.Makhalidwe a semi crystalline polima v amorphous ma polima akufotokozedwa kwina mwatsatanetsatane.Mwachidule, crystalline imathandizira kukana kwa mankhwala ndi makina opangidwa pamwamba pa kutentha kwa galasi (koma pansi pa malo osungunuka).Ma polima aamorphous ndiabwino pankhondo komanso kuwonekera.

Zinthu za PPA

Zinthu za PPA zili ndi zinthu zophatikizira zabwino kwambiri, zomwe zimagwira ntchito bwino pakutentha, magetsi, thupi ndi mankhwala.Makamaka pansi pa kutentha kwakukulu kwa PPA imakhalabe yolimba kwambiri komanso yolimba kwambiri, kuphatikizapo kulondola kwapamwamba komanso kukhazikika.

PPA Main Application Field

Mwapadera kugwiritsa ntchito kalasi yamagalimoto owongolera madzi agalimoto ndi gawo la thupi la thermostat.

Munda	Milandu Yofunsira
Zida Zagalimoto	Auto Water Temperature Control Assemblies, gawo la thupi la thermostat, magawo amapangidwe, pampu yosunthika, gawo la clutch, pampu yamafuta etc.
Zamagetsi ndi Zamagetsi	Cholumikizira, cholumikizira cha SMT, Breaker, socket, bobbins etc.
Makampani olondola komanso zida zamakina	Magawo a pampu yowongolera mphamvu, mbali za uvuni wa nthunzi, zolumikizira ma boiler amadzi otentha, zowonjezera zowotchera madzi
