Cov Ntawv Thov
1. Polyimide Resin Synthesis
PMDA yog qhov tseem ceeb dianhydrig monomer nyob rau hauv kev tsim polyimides, siab-ua thermoplastics paub rau:
Tshwj Xeeb Ntawm Thermal Stability
Neeg Kho Tshuab Muaj Zog
Kev Rwb Hluav Taws Xob
Polyimides yog siv nyob rau hauv Aerospace, Automotive, hloov hluav taws xob, thiab qib siab rwb thaiv tsev cov yeeb yaj kiab (piv txwv li, Kapton®).
2. Epoxy Resin Chais Tus Neeg Sawv Cev
Muaj nuj nqi raws li tus neeg sawv cev tawv lossis tus kws tshuaj tua tus kheej rau epoxy resins, txhim kho:
Tshuaj Kuj
Thermal Performance
Adhesion lub zog
3. Cov nplaum thiab txheej
Cov qauv kub-resistant, choert zaj duab xis.
Ntau yam hauv kev tiv thaiv kev tiv thaiv, tshwj xeeb tshaj yog rau cov hlau thiab hluav taws xob.
4. Polyester thiab Alkyd Resin Hloov Kho
Incorporated rau hauv Alkyd thiab Polyester Resins los txhim kho kev nyuaj thiab tshuaj lom neeg tiv thaiv cov polymer kawg.
5. Composite Cov Khoom Siv
Dav siv nyob rau hauv lub chaw tsim hluav taws xob, tshwj xeeb yog cov khoom siv rov xyaw matrix tiv thaiv rau cov khoom siv fiber ntau ntxiv.
6. Kws ua tshuaj thiab zas xim intermediates
PMDA pabcuam ua lub tsev thaiv cov tshuaj tshwj xeeb synthesis, tshwj xeeb yog qhov twg tsis muaj ntxhiab tsw ntxhiab yog xav tau.
Cov txiaj ntsig
Thermal Stability: Ib qho ntawm feem ntau ua ruaj khov atichydrides muaj, tseem ceeb rau kev siv kub-tshav kub.
Cov pab pawg siab: cov pab pawg anhydride yog qhov ua kom txaus siab rau cov khoom siv roj hmab thiab haus dej, tswj kev sib cais polymerizations.
Cov Khoom Dielectric zoo heev: Qhov tseem ceeb rau cov yeeb yaj kiab microelectronic thiab insulating zaj duab xis.
Versatility: Tau tshaj nrog ntau txoj kab uas cov hlab thiab cov diols, ua kom haum rau kev cai polymer.
Tag
1,2,4,5-benzenetetracarbarboxylic anhydric anhydride (PMDA, CAS 89-32-7) yog qhov tseem ceeb ntawm kev tsim cov kev ua haujlwm siab polymers zoo li polyimides. Nws cov cua nab kuab thiab tshuaj ruaj khov, thiab hluav taws xob rwb thaiv tsev zog ua rau nws cov khoom siv hluav taws xob hauv kev lag luam nrog aerospace, hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov txheej txheem hluav taws xob, thiab cov tsho tiv no zoo. Raws li kev thov loj hlob rau cov khoom siv ruaj khov thiab kub tiv thaiv, PMDA tseem yuav yog cov tshuaj lom neeg hauv cov khoom siv science thiab kev lag luam.
