1,4,5,8-Naphthalenetetracarboxylic dianhydride/NTDA cas:81-30-1

Kufotokozera Kwachidule:

1,4,5,8-naphthalene tetracarboxylic anhydride, yomwe imadziwika kuti NTA, ndi chinthu choyera cha crystalline chokhala ndi mankhwala C12H4O5.Zimapangidwa mosamala pogwiritsa ntchito njira zolondola kuti zitsimikizire kuti ndi zapamwamba komanso zoyera.NTA imagwiritsidwa ntchito ngati zopangira popanga zinthu zosiyanasiyana, zomwe zimathandizira kukulitsa mafakitale ambiri ofunika.

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

- Zakuthupi ndi Zamankhwala: NTA ili ndi molekyu yolemera 244.16 g/mol ndi malo osungunuka a 352-358°C. Imawonetsa kusungunuka kwabwino mu zosungunulira za organic monga chloroform, ethyl acetate, ndi benzene.Kuphatikiza apo, zikuwonetsa kukhazikika bwino pansi pazikhalidwe zabwinobwino, kulola kusungidwa ndi kusuntha popanda kuwonongeka kwakukulu.

- Ntchito: NTA imapeza ntchito m'mafakitale osiyanasiyana, kuphatikiza mankhwala, utoto, ndi mapulasitiki.M'gawo lazamankhwala, ndi gawo lofunikira kwambiri pakuphatikiza mankhwala, zomwe zimathandizira kuti pakhale njira zochiritsira zatsopano.Kuchitanso kwake kwakukulu komanso kuyanjana kumapangitsa kuti ikhale gawo loyenera popanga utoto wapamwamba kwambiri, wopereka mawonekedwe apadera amitundu.Kuphatikiza apo, NTA imagwiritsidwa ntchito ngati monomer pakuphatikizika kwa ma polima apadera ndi utomoni, kupititsa patsogolo magwiridwe antchito komanso kulimba kwawo.

- Zoganizira Zachitetezo: Mukagwira 1,4,5,8-naphthalene tetracarboxylic anhydride, ndikofunikira kutsatira njira zodzitetezera.Chigawochi chiyenera kusungidwa pamalo ozizira, owuma, kutali ndi moto wotseguka kapena magwero oyatsira.Mpweya wabwino ndi wofunikira mukaugwiritsa ntchito kuti mupewe kupuma kwa mpweya uliwonse womwe ungakhalepo.Monga momwe zimakhalira ndi mankhwala aliwonse, ndikofunikira kuvala zida zoyenera zodzitetezera, kuphatikiza magolovesi ndi magalasi, kuti muchepetse kukhudzana ndikuwonetsetsa chitetezo chanu.

Pomaliza, 1,4,5,8-naphthalene tetracarboxylic anhydride ndi mankhwala ofunika kwambiri omwe amagwira ntchito mosiyanasiyana m'mafakitale osiyanasiyana.Maonekedwe ake apadera komanso ntchito zake zambiri zimapangitsa kuti ikhale yofunika kwambiri popanga zinthu zachilengedwe, mankhwala, utoto, ndi mapulasitiki.Tadzipereka kuti tikupatseni NTA yapamwamba kwambiri, yopangidwa mwatsatanetsatane komanso motsatira miyezo yamakampani.
