KAYAMBIDWE:
Kufotokozera:
Isophthalic acid ndi mankhwala achilengedwe okhala ndi formula C6H4(CO2H)2. Cholimba chopanda utoto ichi ndi isomer ya phthalic acid ndi terephthalic acid. Ma aromatic dicarboxylic acid awa amagwiritsidwa ntchito ngati zoyambira (monga acyl chloride) ku ma polima ofunikira pamalonda, mwachitsanzo Nomex yomwe siigwira moto. Yosakanikirana ndi terephthalic acid, isophthalic acid imagwiritsidwa ntchito popanga ma resin a mabotolo akumwa. Polymer poly benzimidazole yogwira ntchito kwambiri imapangidwa kuchokera ku isophthalic acid.

Kagwiritsidwe Ntchito
Isophthalic acid imagwiritsidwa ntchito ngati chothandizira popanga ma polyester osakhuthala omwe amagwira ntchito bwino kwambiri, ma resin opangira zokutira, utoto wolimba kwambiri, ma gel coat ndi modifier ya polyethylene terephthalate yamabotolo. Imagwira ntchito ngati choyambira cha nomex chomwe sichimayaka moto komanso imagwiritsidwa ntchito popanga polyester polybenzimidazole yogwira ntchito kwambiri. Imagwiritsidwanso ntchito ngati chothandizira popanga zinthu zotetezera kutentha.
Acid Yoyeretsedwa ya Isophthalic (PIA) imagwiritsidwa ntchito makamaka ngati yapakati pa UPR yogwira ntchito bwino, ma resin opaka utoto, utoto wolimba kwambiri, ma gel coat, ndi chosinthira PET cha mabotolo.
Kulongedza
25KG/Chikwama kapena malinga ndi zosowa za makasitomala.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
