Matamba a malonda

Polyphthalamide (Aka. PPA wa terephthalic (TPA) ndi isophotio (IPA). Zolowa za Aliphatic amasankha ndi kutanthauzira kwa Polymec Backboation kumawonjezera malo osungunuka, kutentha kusinthitsa galasi, kukana kwa madzi.

Mautupi ozungulira a PPA amapangidwa m'magawo kuti m'malo mwa zitsulo zomwe zimafunikira kukana kutentha kwambiri monga mphamvu yamagetsi zikuluzikulu komanso kugwiritsa ntchito njira zina zambiri.

Kutentha kwagalasi kumawonjezera kuchuluka kwa ma TP. Ngati oposa 55% a asidi a PPA amapangidwa kuchokera ku IPA, ndiye kuti mkuwa ndi amorphous. Mphamvu ya Semi Crystalline ma polity V mormous mabokosi amalongosoledwa kwina konse. Mwachidule, Crystalline amathandizira pokana mankhwala ndi makina opanga pamwamba pa kutentha kwagalasi (koma pansi pa malo osungunuka). Makosi a amorphous ndi abwino kwambiri pabwino komanso kuwonekera.

Zovala za PPA

Zinthu za PPA zili ndi kuphatikiza kwapamwamba, zomwe zimachita bwino pamafuta, zamagetsi, zakuthupi komanso mankhwala. Makamaka kutentha kwambiri kwa PPA kumakhala ndi mphamvu zambiri komanso nyonga yayikulu, pamodzi ndi kulondola kwanzeru komanso kukhazikika.

PPA ikuluikulu ya PPA

Padera pogwiritsa ntchito kalasi ya malo owongolera mafilimu othandizira am'madzi ndi gawo la Thermostat.

Magawo auto	Kutentha kwamadzi kumawongolera misonkhano ikuluikulu, gawo lamthupi la thermostat, malo opangira, pampu wamphamvu, gawo la clutch, pampu yamafuta etc.
Zamagetsi ndi zamagetsi	Cholumikizira, SMT cholumikizira, breaker, socket, bobbins etc.
Makampani opanga mafakitale ndi zigawo za mechnical	Mphamvu yowongolera mphamvu, zigawo za utoto, zophatikiza zotentha zamadzi zotentha, zowonjezera madzi
