Kugwiritsa ntchito

3,3 '3,4'-4'-4'-bIPHYLTTECARYOXYXYIC Dianydride (BPDA)ndi gawo lofunikira munthawi yakale ndipo lili ndi ntchito zingapo:

Polymide synthesis

• Mafilimu oyendetsa bwino: imatha kuthana ndi ma polycondedetion ndi ma diamine mankhwala kupanga mafilimu a Polymira. Makanema awa ali ndi chitetezo chamu kutentha kwambiri. Ngakhale malo otentha kwambiri kuposa 200 ° C, amatha kukhalabe ndi mphamvu zamakina ndi magetsi amagetsi. Chifukwa chake, nthawi zambiri amagwiritsidwa ntchito mu gawo la Aerossace kutchinjiriza kwa motars ndi zida zamagetsi kapena ngati maziko a matabwa osinthika osindikizidwa.
• Mapulasitiri a engirirani: Mabwalo a Polynturide polymiriraning avisiketi ali ndi mphamvu kwambiri, kulimba mtima, komanso kutopa. Amatha kukhala jakisoni - wopangidwa kupanga magawo ena ogwiritsa ntchito makina, monga mabatani ang'onoang'ono kuzungulira ma injini a ndege ndi mbali zina zapamwamba.
• Munda wokutira: Zovala za Polyridide zophatikizika zochokera ku BPDA Khalani ndi mankhwala ochulukirapo a mankhwala. Akagwiritsidwa ntchito kumakoma amkati mwa akasinja osungirako mankhwala ndi makonda, amatha kuthana ndi kukokoloka kwa asidi osiyanasiyana, zitsulo, komanso zosungunulira kwakanthawi, ndikuwonetsetsa moyo wa zida. Nthawi yomweyo, nawonso ali ndi pokana ndi kutentha. Mukakulungidwa pamapaipi ndi mapangidwe a injini, sangasunthe mosavuta chifukwa cha kutentha kwambiri.
• Zipangizo: Zimagwiritsidwa ntchito popanga ulusi wambiri. Zilonda za Polymiya zimapangidwa zimakhala ndi mphamvu zambiri, modulus kwambiri, komanso kukhazikika kwamphamvu kwambiri. Nthawi zambiri amagwiritsidwa ntchito popanga zinyalala zamoto, zingwe zapadera za Aerospace, etc., kupereka chitetezero chodalirika kwa ogwira ntchito ndi zida zamagetsi kwambiri komanso zoopsa zapamwamba.

Kutumiza ndi kutumiza

20kg / Drum kapena monga zofunikira zamakasitomala.
Ndi wa zinthu wamba ndipo amatha kupulumutsa ndi nyanja ndi mpweya

Pitilizani ndikusunga

Moyo wa alumali: Mwezi 24 kuyambira tsiku lopanga mu phukusi lokhazikika losagwirizana ndi dzuwa louma, madzi.
Chosokoneza chosungira, kuyanika kwa kutentha kochepa, kupatulidwa ndi oxidants, ma acid.
