Pyromellitic Dianhydride CAS89-32-7/PMDA

Kagwiritsidwe Ntchito

Pyromellitic Dianhydride ingagwiritsidwe ntchito popanga polyimide resin, yomwe imagwiritsidwa ntchito ngati zinthu zopangira utoto woteteza magetsi womwe sutentha kwambiri. Imagwiritsidwanso ntchito popanga epoxy resin curing agents ndi plasticizers, urea formaldehyde resin stabilizers, phthalocyanine blue dyes, corrosion inhibitors, instant binders, electronic photography toners, ndi zina zotero.

Pyromellitic Dianhydride ndi zinthu zochokera ku pyromellic zimagwira ntchito zosiyanasiyana. PMDA imagwiritsidwa ntchito makamaka ngati chothandizira kuchiritsa utomoni wa epoxy, zinthu zopangira polyimide, komanso chothandizira kulumikiza utomoni wa polyester kuti apange utomoni wa polyetherimine wa homopolymer. Ichi ndi chinthu chopangidwa ndi uinjiniya chomwe chimagwiritsidwa ntchito kutentha kwambiri chomwe chingagwiritsidwe ntchito nthawi zonse kwa nthawi yayitali pa 2600C.

Zipangizo zazikulu zomwe zimagwiritsidwa ntchito popanga mapulasitiki ndi mafilimu oteteza kutentha a polyimide; Zingagwiritsidwe ntchito ngati zopangira zopangira epoxy resin curing agent, stabilizer, ndi utoto, ndi zina zotero.

Pyromellitic Dianhydride ingagwiritsidwe ntchito popanga polyimide resin, utoto woteteza magetsi womwe sutentha kwambiri, PVC plasticizer, synthetic resin crosslinking agent, ndi epoxy resin curing agent. Imagwiritsidwanso ntchito popanga phthalocyanine blue dye, ndi zina zotero.

Kulongedza ndi Kutumiza

25KG/Drum kapena katoni ya 20kg kapena malinga ndi zomwe makasitomala akufuna
Ndi ya 6.1 hazard ndipo imatha kutumizidwa kudzera panyanja

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 6 kuyambira tsiku lopangidwa m'mabokosi oyamba osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
samalani ndi chinyezi.
