gadzira vhezheni yakasiyana CTBN Carboxyl yakagumiswa butadiene nitrile rubber(CTBN) CAS 25265-19-4 Carboxyl-Yapera Butadiene-Acrylonitrile CAS 68891-46-3
Iyo yemvura carboxyl-yakapera butadiene acrylonitrile imwe mhando yerabha yemvura ine carboxyl boka seboka rebasa, uye iyo kodhi ndeyeCTBN, inogona kushandiswa kazhinji munzvimbo dzendege uye dzevagari vemo maindasitiri. Kazhinji CTBN inoshandiswa yakasanganiswa ne somatotype resin. Iyo CTBN ine inoshanda carboxyl-yakamiswa boka inogona kuita pane epoxy resin kuitira kuti iwedzere kuoma.
1. Inowedzera kuoma uye kushanduka kwe thermoset resins
2. Inovandudza kunamatira kune substrates iyo yakaoma kubatanidza
3. Inowedzera kukanganisa uye kusagadzikana kwekuputika
4. Inovandudza kusimba (kuramba kuneta)
5. Inowedzera yakaderera-kupisa mechanical properties
6. FDA shanduro iripo
1. CTBN yakanakisa flexibility modifier ye thermosetting resins senge epoxy, phenolic, unsaturated polyester uye photosensitive resins. Inogona kuvandudza brittleness kuramba uye kuputika kuramba kwechigadzirwa chekupedzisira.
2. Metallic adhesive yakagadzirwa kubva epoxy resin iyo inogadziriswa neCTBN (acrylonitrile content is 25%), ine kuoma kwakanaka, kushanduka uye kuneta kuramba. Inogona kushandiswa kusungira zvikamu zvendege, pamwe chete negirazi rehupenyu uye terylene bhandi. Iri rinonamira zvakare rinogona kushandiswa sekunamira kwekunamira kweakasiyana machira zvinhu senge girazi fiber, terylene uye kabhoni fiber.
3. Iyo inonamira iyo inogadzirwa kubva kuCTBN uye epoxy resin inogona kurapa pane yakajairika tembiricha, inogona kushandiswa kusungira aluminous zvinhu, inosvika pakunamira kwepamusoro-soro mushure memaawa makumi manomwe nemaviri. Iyo peel- intensity ndeye 0.55MPa, uye kucheka kusimba i26.7MPa. Iyo yemagetsi element sealant zvinhu inogadzirwa neCTBN yakagadziridzwa epoxy, iyo inosimudzira kuramba kwekupwanya, haizove nekutsemuka mushure me200 nguva yekudzokorodza pane tembiricha iri pakati -55.0 ℃ kusvika 150 ℃.
4. Iyo CTBN inogona kushandiswa seyakanamatira mukukuya uye kucheka gumbo, ine zvikomborero zvekunamatira zvishoma asi zvakanyanya kupikisa, pamwe nekushanda kwepolish yakanaka, kupisa kwemvura inopisa.
5. CTBN inonyanya kushandiswa sebhainda kune yakasimba rocket propellants.
6. nezvimwewo...
Yakarongedzwa mu50kg / drum, 170kg / drum, Nguva yekuchengetedza ndeye 1 gore.
Mirayiridzo yekuchengetedza:
Kuchengetera kunofanirwa kunge kuchitonhorera, kuoma uye kufefetera. Mamiriro akanaka ari pakati -20 ~ 38 ℃. Sherufu yemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika pachiyero kuburikidza nekuongororazve. Apo kutakurwa kunofanira kudzivisa mvura, chiedza chezuva. Usasanganise neoxidizer yakasimba.
