Pyromellitic DianhydrideCAS2420-87-3: "Bhiza Rine Rima" Mumunda Wezvinhu Zvitsva Zvemakemikari Rinokwezva Kutarisirwa Kwemaindasitiri

Munguva pfupi yapfuura, pakati pekukura kuri kuita indasitiri yemakemikari, pyromellitic dianhydride (PMDA), chinhu chakakosha, chakanyanya kutaurwa nezvacho, chichikurudzira zvikuru kuvandudzwa kwezvinhu zvakawanda zvepamusoro uye chichikonzera kutsvagurudzwa kutsva muindasitiri, zvikoro zvepamusoro, uye munharaunda dzekutsvaga.

Sechinhu chakakosha chemakemikari eorganic, pyromellitic dianhydride ingaratidzika seisingashamisi pakutanga, asi ine hunyanzvi hwakasiyana. Kubva kudivi rekugadzira, makambani mazhinji emakemikari emuno ari kuwedzera kuedza kwavo kusimudzira nekuwedzera nzira dzavo dzekugadzira. [Zita reKambani] Chemical Co., Ltd. ichangopedza kugadzirisa nekugadzirisa maitiro ekugadzira pyromellitic dianhydride. Tekinoroji itsva iyi inoshandisa sisitimu yekudzora yakangwara inonyatso gadzirisa zvinhu zvakakosha zvakaita sekupisa kwe reaction uye kumanikidzwa. Izvi zvakawedzera kuchena kwechigadzirwa neinenge 3 muzana uye zvakaderedza zvakanyanya kuchena kwechinhu. Hazvingovimbisi chete kugadzikana kwemhando yezvigadzirwa zvinotevera asiwo zvinovandudza zvikuru kushanda zvakanaka kwekugadzira, nekubuda kwechikamu chimwe nechimwe kuchiwedzera neanopfuura 20%, zvichipa kambani mukana wekutanga mumusika une makwikwi makuru.

Mubasa rekushandisa, pyromellitic dianhydride inopenya zvakanyanya. Mapoka ekutsvagisa ari kugara achitsvaga kugona kwayo mukugadzira zvinhu zvinoshanda zvakanyanya. Panyaya yezvinhu zvemagetsi, firimu repolyimide rakagadzirwa kubva mariri rine ukobvu hunosvika hafu yezvinhu zvechinyakare zvekudzivirira kupisa, asi rinogona kutsungirira mavolts anosvika mazana akawanda evolts, rine dielectric constant yakagadzikana, uye hunhu hwakanaka hwekupisa, zvichipa mhinduro yakanaka kudambudziko rekudzivirira kupisa nekurongedza machipisi madiki, akanyatsogadzirwa mumidziyo yekutaurirana ye5G uye kunyange yeramangwana ye6G. Bhizinesi rinotungamira retekinoroji yemagetsi rasvika pakubatana kwakasimba nevatengesi vezvinhu zvakabikwa uye rave kutungamira mukuyedza zvigadzirwa zvemachipisi zvakashongedzerwa nefirimu idzva repolyimide, richiedza kuva pamberi mumakwikwi ezvigadzirwa zvetekinoroji yekutaurirana yechizvarwa chinotevera.

Chikamu chemuchadenga hachisiriwo kusara shure. Nekuda kwehunhu hwepamusoro-soro uye hunodzivirira mwaranzi hwezvinhu zvakagadzirwa kubva ku pyromellitic dianhydride, mapurasitiki einjiniya akakodzera anoshandiswa kugadzira zvinhu zvinodzivirira zvakareruka pamipendero yemapapiro endege. Zvichienzaniswa nezvinhu zvesimbi zvechinyakare, zvinoderedza huremu neanopfuura 30%, zvichideredza kushandiswa kwemafuta uye zvichibatsira mota dzemuchadenga kubhururuka kure uye zvakagadzikana. Uyezve, kana zvinhu zvakagadzirwa kubva muchinhu ichi zvikabatanidzwa muzvikamu zvekudzivirira zvekunze zvetambo dzakakosha dzemaprobes emuchadenga, zvinogona kutsungirira mwaranzi yakanyanya yemuchadenga uye kusiyana kwekushisa, zvichiita kuti data ritapurirwe zvakanaka panguva yemabasa akaoma emuchadenga.
