CTBN Carboxyl terminated butadiene nitrile roj hmab (CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 68891-46-3
Cov kua carboxyl-terminated butadiene acrylonitrile yog ib hom kua roj hmab uas muaj carboxyl pawg raws li nws yog pawg ua haujlwm, thiab nws cov cai yog CTBN, tuaj yeem siv dav hauv aviation thiab civil industrial cheeb tsam. Feem ntau CTBN yog siv ua ke nrog somatotype resin. CTBN uas muaj cov pab pawg ua haujlwm carboxyl-tshem tawm tuaj yeem hnov mob ntawm epoxy resin thiaj li txhim kho qhov tawv.
1. Txhim kho qhov toughness thiab yooj ntawm thermoset resins
2. Txhim kho adhesion rau substrates uas nyuaj rau kev sib txuas
3. Ua kom muaj kev cuam tshuam thiab tawg tsis kam
4. Txhim kho durability (kev qaug zog tsis kam)
5. Ua kom cov khoom siv hluav taws xob qis qis
6. FDA version muaj
1. CTBN yog ib qho zoo heev hloov kho 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 nplaum ua los ntawm epoxy resin uas tau hloov kho los ntawm CTBN (acrylonitrile cov ntsiab lus yog 25%), muaj zog toughness, yooj thiab qaug zog. Nws tuaj yeem siv los txuas cov khoom siv dav hlau, nrog rau cov iav organic thiab terylene siv. Cov nplaum no kuj tseem siv tau los ua cov nplaum nplaum ntawm ntau yam ntaub ntawv xws li iav fiber, terylene thiab carbon fiber.
3. Cov nplaum nplaum uas yog tsim los ntawm CTBN thiab epoxy resin tuaj yeem kho ntawm qhov kub thiab txias, tuaj yeem siv los khi cov ntaub ntawv aluminous, nws yuav ncav cuag qhov nplaum siab tshaj plaws tom qab 72 teev. Kev siv lub tev yog 0.55MPa, thiab kev siv zog yog 26.7MPa. Cov khoom siv hluav taws xob sib khi ua los ntawm CTBN hloov kho epoxy, uas txhim khu kev sib tsoo, yuav tsis muaj qhov tawg tom qab 200 zaug rov ua dua ntawm qhov kub ntawm -55.0 ℃ to 150 ℃ .
4. Lub CTBN tuaj yeem siv los ua cov nplaum rau hauv kev sib tsoo thiab txiav lub log, nws muaj cov txiaj ntsig ntawm cov nplaum tsawg tab sis muaj kev puas tsuaj ntau dua, nrog rau kev ua haujlwm zoo ntawm polishing, dej kub tsis kam.
5. CTBN feem ntau yog siv los ua cov ntawv khi rau cov khoom siv foob pob hluav taws.
6. lwm..
Ntim hauv 50kg / nruas, 170kg / nruas, Lub sijhawm cia yog 1 xyoos.
Cov lus qhia kev nyab xeeb:
Kev khaws cia yuav tsum tau txias, qhuav thiab ventilate. Qhov zoo tshaj plaws mob yog ntawm -20 ~ 38 ℃. Txee lub neej ntawm 12 lub hlis, yog tias tas sij hawm, tseem siv yog tias mus txog tus qauv los ntawm kev rov kuaj dua. Thaum kev thauj mus los yuav tsum tsis txhob los nag, tshav ntuj. Tsis txhob sib tov nrog oxidizer muaj zog.
