Tinoziva kuti tinobudirira chete kana tikakwanisa kuvimbisa kukwikwidzana kwemitengo yedu pamwe chete uye zvakanaka panguva imwe chete. , Iye zvino tinofanira kuramba tichitsigira pfungwa yebhizinesi "yemhando yepamusoro, yakadzama, inoshanda zvakanaka" yepfungwa yebasa "yakavimbika, ine mutoro, ine hunyanzvi", kutevedzera chibvumirano uye kutevedzera mukurumbira, zvinhu zvepamusoro uye kuvandudza sevhisi, kugamuchira vatengi vekunze kwenyika.
3,3 ', 4,4′ – Biphenyltetracarboxylic dianhydride chinhu chakakosha chepolyimide monomer chinoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvepolyimide zvinodzivirira kupisa kwakanyanya. Chinoshandiswa pakugadzira zvigadzirwa zvepolyimide nezvinhu zvadzo zvakasanganiswa, mishonga yepakati.
CAS 2420-87-3 ye3,3′,4,4′-Biphenyltetracarboxylic dianhydride chimiro chakakosha uye chinonhuhwirira chinonaka chedianhydride, uye zvakare imonomer huru yekugadzira zvinhu zvepolymer zvine simba guru. Ine nzvimbo isingatsiviwe muminda yakaita seyemuchadenga, ruzivo rwemagetsi, uye michina yepamusoro-soro.

3,3′,4,4′-Biphenyltetracarboxylic dianhydride (CAS 2420-87-3, yakapfupikiswa seBPDA) imonomer huru yekugadzira zvinhu zvepolymer zvinoshanda zvakanyanya, uye mashandisirwo ayo anonyanya kutarisana nenzvimbo yezvinhu zvepamusoro-soro.
1. 3,3′,4,4′-Biphenyltetracarboxylic dianhydride inoshandiswa sezvikamu zvechimiro zvinodzivirira kupisa kwakanyanya zvemuchadenga (sezvakaita zvikamu zvemunzvimbo yesatellite casings) uye machira ekudzivirira kupisa ezvikamu zveinjini; Chikamu cheantenna chinochinjika chemidziyo uye chikamu chekudzivirira tambo chinodzivirira kupisa kwakanyanya.
2. BPDA inogona kushandiswa mumasekete akabatanidzwa (ics): kugadzirira mafirimu ekudzivirira anopindirana, kuderedza kushanduka kwehukuru kunokonzerwa nekupisa kwemachipisi, uye kuwedzera kugadzikana kwemachipisi. Inogadzirwa muzvinhu zvePI (zvakadai sefibre yekabhoni yakazadzwa negrafiti), izvo zvinoshandiswa mumabheringi nemaseki mumamiriro ekushanda anopisa zvakanyanya (zvakadai sekuvhara zvikamu zveinjini dzemotokari nemidziyo yemakemikari), kutsiva zvinhu zvesimbi kuderedza kupera nekuora.
3. Kunze kwepolyimide, BPDA inogonawo kuita nemamonomers akasiyana kuti igadzire zvimwe zvinhu zvinoshanda zvepolymer, zvichiwedzera miganhu yekushandisa kwayo
Synthetic polyamideimide (PAI): BPDA inopindirana ne diisocyanate kuti igadzire PAI. Rudzi urwu rwezvinhu runobatanidza kuramba kupisa kwakanyanya kwePI uye kuramba kukanganiswa kwe polyamide, uye inogona kushandiswa kugadzira zvikamu zvepurasitiki zvepamusoro-soro.
Synthetic polyetherimide (PEI): Inoshanda nemadiamine ane ether bonds kuti igadzire PEI. Kugona kwayo kugadzikiswa kwakanaka kupfuura kwePI yechinyakare. Inogona kugadzirwa kuita magoko emidziyo yemagetsi uye maconnector anodzivirira kupisa kwakanyanya kuburikidza nejekiseni, tichifunga nezvesimba uye nyore kushandisa.
4. Mapoka eanhydride ari mumorekuru yeBPDA anogona kuita ring-opening reactions nemapoka epoxy e epoxy resin uye anogona kushandiswa semishonga inoporesa inodzivirira kupisa kwakanyanya:
4,4′-Biphthalic Anhydride 2420-87-3 inonyanya kushandiswa pakugadzira "zvinhu zvinosanganiswa zve epoxy zvinodzivirira kupisa kwakanyanya", zvakaita sekubvisa midzi yemashizha e wind turbine (anofanira kutsungirira kukwegura kwekunze kwenguva refu) uye kudzima epoxy substrates dzemabhodhi edunhu repamusoro, kuwedzera kugadzikana kwekupisa (Tg yezvinhu zvakagadziriswa inogona kuwedzerwa kusvika pamusoro pe180℃) uye simba remagetsi rezvinhu zve epoxy.
Kazhinji inorongedzwa mu 25kg/dhiramu, uye inogonawo kugadzirwa nepakeji yakagadzirwa.
Tinoziva kuti tinobudirira chete kana tikakwanisa kuvimbisa kukwikwidzana kwemitengo yedu pamwe chete uye kunobatsira zvikuru panguva imwe chete kuOEM Manufacturer 3, 3′, 4, 4′-Biphenyltetracarboxylic Dianhydride/Bpda CAS 2420-87-3 yeOrganic Synthesis. Tinogamuchira vatengi, masangano emabhizinesi nevamwe vanobva kumativi ese epasi kuti vataure nesu uye vatsvage kushandira pamwe kuti tiwane zvinhu zvakanaka.
Mugadziri weOEM 3 3'44′-Biphenyltetracarboxylic Dianhydride neBpda, Iye zvino tinofanira kuramba tichitsigira pfungwa yebhizinesi "yemhando yepamusoro, yakadzama, inoshanda zvakanaka" yepfungwa yebasa "yakavimbika, ine mutoro, ine hunyanzvi", kutevedzera chibvumirano uye kutevedzera mukurumbira, zvinhu zvepamusoro uye kuvandudza sevhisi yekugamuchira vatengi vekunze kwenyika.
