Kutentha Kwambiri kwa Nylon PPA Makhalidwe ndi Ntchito Zazikulu

Makhalidwe azinthu za PPA

1, PPA ndi chinthu chopanda kutentha kwambiri, chokhala ndi malo osungunuka pakati pa 310-325 ° C ndi kutentha kosokoneza kutentha (HDT) pakati pa 280-290 ° C.

2, PPA ili ndi kukana kwamafuta abwino kwambiri komanso kukana kwambiri kwamafuta osiyanasiyana monga mafuta amafuta ndi mafuta opaka, ngakhale kutentha kwambiri kwa 150 ℃

3, PPA ili ndi kukhazikika kwabwino kwambiri komanso tsamba lochepa lankhondo

4, Mayamwidwe amadzi a PPA ndi otsika kwambiri kuposa PA6 kapena PA66, ndipo mphamvu yake yokhazikika imatha kukhala pamwamba pa 80% ngakhale atamizidwa m'madzi ozizira kwa zaka zingapo.

5, PPA imalimbana bwino ndi nyengo ndipo ndiyoyeneranso kugwiritsidwa ntchito kwanthawi yayitali panja nyengo yoyipa monga ma radiation a UV, chinyezi chachikulu, komanso kutentha kwambiri.

6, PPA ili ndi magwiridwe antchito abwino kwambiri achilengedwe ndipo imatha kufikira mulingo wa US FDA

Malo ogwiritsira ntchito PPA

Makampani opanga magalimoto:zida zomangira, ma thermostat housings, mapampu amphamvu, magawo a clutch, mapampu amafuta, ndi zina zambiri.

Zamagetsi ndi zamagetsi:zolumikizira, zolumikizira za SMT, zowononga madera, mipata yamakhadi, ndi zina zambiri.

Makampani opanga makina:mapampu amadzi, Chalk mpope mafuta, impellers, zovekera madzi otentha chitoliro, mayendedwe, magiya, etc.

Zofunikira tsiku ndi tsiku:mapampu amadzi, Chalk mpope mafuta, impellers, zovekera madzi otentha chitoliro, mayendedwe, magiya, etc.

Makampani opanga magalimoto

Zipangizo zama PPA zolimba kwambiri zamagalimoto zili ndi mawonekedwe abwino kwambiri.Pofuna kukwaniritsa zofunikira pakugwiritsa ntchito zida zamagalimoto, zida zolimbikitsidwa za PPA zili ndi izi:

Mkulu mphamvu, mkulu rigidity

Kukana kwabwino kwambiri, kutopa komanso kukana kugwedezeka

Kukhazikika kwapamwamba kwambiri

Kukana kwa Chemical kumafuta amagalimoto, zamadzimadzi ndi mafuta

High kutentha kukana, akupanga kuwotcherera kukana;

Zabwino machinability ndi zolimba nkhungu kulolerana.

Zamagetsi ndi zamagetsi

Zida za PPA zogwira ntchito kwambiri pamagetsi ndi zamagetsi zili ndi katundu wabwino kwambiri.Pofuna kukwaniritsa zofunikira pamagetsi ndi zamagetsi, zida zowonjezeredwa za PPA zili ndi izi:

Kutentha kosokoneza kutentha (HDT) kupitirira 270°C

Kukhazikika kwapamwamba kwambiri;

Mphamvu yayikulu, modulus yayikulu, mphamvu yayikulu kwambiri

Kuthamanga kwakukulu ndi kuchepa kochepa kwa kuumba mwatsatanetsatane

Kutentha kwakukulu ndi kukana kwa solder

Kusungunula kwabwino kwamagetsi

Ukachenjede wazitsulo

Zida zogwira ntchito kwambiri za PPA zamakina zili ndi katundu wabwino kwambiri.Pofuna kukwaniritsa zofunikira pakugwiritsa ntchito makina am'makina, zida zolimbikitsidwa za PPA zili ndi izi:

Kukana kutentha kwakukulu, kutentha kupotoza kutentha pamwamba pa 270 ℃

Chemical resistance

Mphamvu zazikulu, zotsutsana ndi kutopa

Kukhazikika kwapamwamba kwambiri

Zabwino kwambiri kukana madzi otentha

Kukana kwabwino kwa mafuta

Zofunika tsiku ndi tsiku

Zida za PPA zogwira ntchito kwambiri pazofunikira zatsiku ndi tsiku zili ndi katundu wabwino kwambiri.Kuti akwaniritse zofunikira pakugwiritsa ntchito zofunikira zatsiku ndi tsiku, zida zolimbikitsidwa za PPA zili ndi izi:

Kukana kutentha kwakukulu

Chemical resistance, kutopa kukana

Mphamvu zabwino kwambiri komanso kukhulupirika kwamakina

Kukhazikika kwapamwamba kwambiri

Zogwirizana ndi FDA
