3,3 ', 4,4-biphenyltetracarcarcarcarcarcardil dianhydride Cas: 2420-87-3 3

Kushandiswa

3,3 ', 4,4-biphenyltetracarcarcarcarcarcardilic dianhydride (BPDA)Inzvimbo yakakosha yepakati mu organic synthesis uye ine huwandu hwakawanda hwekushandisa:

Polyimide synthesis

• Yakakwirira-performa mafirimu: Inogona kuitwa neyakaitwa polycondeonsation ne diamine compound kuburitsa mafirimu eblyimi. Iyi mafirimu ane yakanakisa kupisa-kupisa kuramba. Kunyangwe mune yakakwirira-tembiricha yakakwirira pamusoro pa200 ° C, ivo vanogona vachiri kuchengeta zvinhu zvakanaka zvemakaniki uye magetsi ekusimbisa kwemagetsi. Naizvozvo, ivo vanowanzoshandiswa munhamba yeAerospace yekudzivirira kwekusimbirira kweMotors uye magetsi emidziyo kana seyakagadzirwa zvinhu zvakadhindwa wedunhu redunhu rakadhindwa.
• Mainjiniya mapurasitiki: Iyo yakashongedzwa polyimi engineering mapurasitiki ane simba rakanyanya, rakaomesesa, uye rakapfekedzawo. Vanogona kuve vakaumbwa kuti vagadzire zvimwe zvakanyatsoita zvikamu zvine chekuita nemakwenzi emakwenzi, akadai madiki mabhureki akatenderedza mainini enguruve uye ekuendesa mukati medzimisi dzakakwirira-dzekupedzisira manhamba.
• Coating munda: Polyimide Coatings Synthicised zvichienderana neBPDA ine yakanakisa kemikari kurwisa. Kana zvichishandiswa kumadziro emukati emakemikari ekuchengetedza emakemikari uye anokwanisa kudzivisa kuora kweacids akasiyana-siyana, zvigadziko zvemidziyo kwenguva yakareba, achivimbisa hupenyu hwebasa remidziyo. Panguva imwecheteyo, ivo zvakare vane vakanaka vanopikisa. Kana akabatanidzwa pane yakakwirira-tembiricha yekushambadzira pombi uye injini casing, ivo havazopfigire zviri nyore nekuda kwekupisa kwakanyanya.
• Fiber zvinhu: Iyo inoshandiswa kugadzira yakakwirira-performance fibers. Mabhebhi ekurapa akagadzirwa ane simba rakakwirira, akakwira mwerulus, uye kugadzikana kwakanaka kwazvo. Ivo vanowanzoshandiswa kuburitsa masutu emoto, tambo dzakakosha dzekushandiswa, nezvimwewo, zvichivandudza zvakavimbika kune vashandi nemidziyo yakakwira uye yepamusoro-njodzi.

Kurongedza uye kutumira

20kg / chigubhu kana seinodiwa nevatengi.
Ndezvimwe zvinhu zvakajairika uye zvinogona kuburitsa negungwa uye mhepo

Chengetedza nekuchengetedza

HEREF Hupenyu: Mwedzi wemakumi maviri nemana kubva pazuva rekugadzira mukutanga kwekusarongeka kwekuchengetwa munzvimbo inotonhorera yakaoma yezuva, mvura.
Wantiallated Warehouse, kupisa kwakadzika kuoma, kuparadzaniswa kubva ku odifrilan, acids.
