tsim cov qauv sib txawv ntawm CTBN Carboxyl terminated butadiene nitrile roj hmab (CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 25265-19-4 / 68891-46-3
Cov kua carboxyl-terminated butadiene acrylonitrile yog ib hom roj hmab uas muaj carboxyl pawg ua haujlwm, thiab nws tus lej yog CTBN, tuaj yeem siv dav hauv kev lag luam dav hlau thiab kev lag luam pej xeem. Feem ntau CTBN yog siv ua ke nrog somatotype resin. CTBN uas muaj cov carboxyl-terminated pawg nquag tuaj yeem ua rau epoxy resin kom txhim kho qhov tawv.
CTBN tuaj yeem siv tau ua:
- Cov nplaum, kev sib txuas, kev sib khi, kev txau, kev cog qoob loo (aerospace, automotive, hluav taws xob / electronics, kev lag luam. marine thiab kev siv hauv kev tsim kho ...)
- Cov txheej txheem (kua, hmoov, dej)
- CTBN yog qhov nyuaj rau epoxy resin thiab muaj kev hloov pauv zoo heev rau thermosetting resins xws li epoxy, phenolic, unsaturated polyester thiab photosensitive resins.
1. Ua kom cov thermoset resins muaj zog thiab yooj ywm dua
2. Txhim kho kev sib txuas rau cov substrates uas nyuaj rau kev sib txuas rau
3. Ua kom muaj kev cuam tshuam thiab kev tawg tsis kam
4. Txhim kho kev ruaj khov (kev tiv taus kev qaug zog)
5. Ua kom cov khoom siv kho tshuab qis dua
6. FDA version muaj
1. CTBN yog ib qho kev hloov pauv zoo heev rau cov thermosetting resins xws li epoxy, phenolic, unsaturated polyester thiab photosensitive resins. Nws tuaj yeem txhim kho brittleness tsis kam thiab tawg tsis kam ntawm cov khoom kawg.
2. Cov nplaum ua los ntawm cov epoxy resin uas tau hloov kho los ntawm CTBN (acrylonitrile cov ntsiab lus yog 25%), muaj kev tawv zoo, yooj ywm thiab tiv taus qaug zog. Nws tuaj yeem siv los txuas cov khoom ntawm lub dav hlau, nrog rau cov iav organic thiab terylene siv. Cov nplaum no kuj tuaj yeem siv ua cov nplaum seeping ntawm ntau yam ntaub ntawv xws li iav fiber, terylene thiab carbon fiber.
3. Cov nplaum uas ua los ntawm CTBN thiab epoxy resin tuaj yeem kho tau ntawm qhov kub ib txwm, siv tau los txuas cov khoom siv txhuas, nws yuav ncav cuag qhov nplaum siab tshaj plaws tom qab 72 teev. Qhov tawv tawv yog 0.55MPa, thiab qhov tawv tawv txiav yog 26.7MPa. Cov khoom siv hluav taws xob sealant uas tsim los ntawm CTBN hloov kho epoxy, uas ua kom muaj kev tiv thaiv kev tawg, yuav tsis muaj qhov tawg tom qab rov ua dua 200 zaug ntawm qhov kub ntawm -55.0 ℃ txog 150 ℃.
4. Lub CTBN siv tau ua cov nplaum rau hauv kev sib tsoo thiab txiav log, nws muaj cov txiaj ntsig ntawm cov nplaum tsawg dua tab sis kev tiv thaiv kev sib txhuam ntau dua, nrog rau kev ua tau zoo ntawm kev txhuam zoo, tiv taus dej kub.
5. CTBN feem ntau yog siv ua ib qho binder rau cov khoom siv foob pob hluav taws khov kho.
6. CTBN rau Coatings (kua, hmoov, dej ntws).
7. Thiab lwm yam ntau yam kev siv
Ntim rau hauv 50kg / nruas, 180kg / nruas, Lub sijhawm cia khoom yog 1 xyoos.
Cov lus qhia txog kev nyab xeeb:
Kev khaws cia yuav tsum tau khaws cia rau qhov chaw txias, qhuav thiab muaj cua nkag. Qhov kub zoo tshaj plaws yog -20 ~ 38 ℃. Lub sijhawm khaws cia yog 12 lub hlis, yog tias tas sij hawm, tseem siv tau yog tias ua tau raws li tus qauv los ntawm kev rov kuaj dua. Thaum thauj mus los yuav tsum tsis txhob los nag lossis tshav ntuj. Tsis txhob sib tov nrog cov tshuaj oxidizing muaj zog.
