Tegura ubwoko butandukanye bwa CTBN Carboxyl terminated butadiene nitrile rubber (CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 25265-19-4/68891-46-3
Butadiene acrylonitrile y’amazi ya karubokisili ivanwaho ni ubwoko bumwe bwa karubokisili y’amazi ifite itsinda rya karubokisili nk’itsinda ry’imikorere yayo, kandi kode yayo ni CTBN, ishobora gukoreshwa muri rusange mu ndege no mu nganda za gisivili. Ubusanzwe CTBN ikoreshwa hamwe na somatotype resin. CTBN ifite itsinda rikora rya karubokisili ivanwaho ishobora gukora kuri epoxy resin kugira ngo yongere ubukana.
CTBN ishobora gukoreshwa nka:
- Kole, gufatanya, gufunga, gutera imiti, gusya (ikirere, imodoka, amashanyarazi/ibikoresho by'ikoranabuhanga, inganda, amazi yo mu mazi n'ubwubatsi...)
- Ibikoresho byo gusiga (umuti, ifu, amazi)
- CTBN ikomeye kuri epoxy resin kandi ifite uburyo bwo guhindura imiterere y’ingufu mu miterere y’ingufu nka epoxy, phenolic, polyester idafite ubushyuhe n’ingufu zifata urumuri.
1. Yongera ubukomere n'ubushobozi bwo koroshya ubwiza bwa thermoset resins
2. Binoza uburyo bwo gufatana n'ibintu bigoye gufatana na byo
3. Yongera ingaruka no kurwanya imivuniko
4. Yongera uburambe (kurwanya umunaniro)
5. Yongera imiterere y'ubushyuhe buri hasi mu buryo bw'ikoranabuhanga
6. Verisiyo ya FDA irahari
1. CTBN ni uburyo bwiza bwo guhindura imiterere y’ibice bya thermosetting nka epoxy, phenolic, polyester idafite ubushyuhe n’ibice bya fotosensi. Bishobora kongera ubushobozi bwo kudacika intege no kudacika intege kw’ibicuruzwa bya nyuma.
2. Kole y'icyuma ikozwe muri epoxy resin ihindurwa na CTBN (ingano ya acrylonitrile ni 25%), ifite ubukomere bwiza, ubworoherane kandi irwanya umunaniro. Ishobora gukoreshwa mu guhuza ibice by'ubutaka, ndetse n'ibirahure by'umwimerere n'umukandara wa terylene. Iyi kole ishobora kandi gukoreshwa nk'ikole itonyanga mu bikoresho bitandukanye by'imyenda nka fibre y'ikirahure, terylene na fibre ya karuboni.
3. Kole ikorwa muri CTBN na epoxy resin ishobora gushya ku bushyuhe busanzwe, ishobora gukoreshwa mu guhuza ibikoresho bya aluminiyumu, izagera ku bushyuhe bwinshi nyuma y'amasaha 72. Ubushyuhe bw'igishishwa ni 0.55MPa, naho ubushyuhe bwo gukata ni 26.7MPa. Ibikoresho by'amashanyarazi bifunga ibintu byakozwe na CTBN modulated epoxy, byongera ubukana bwo gucika, ntibizagira imvune nyuma yo kongera gukoreshwa inshuro 200 ku bushyuhe buri hagati ya -55.0℃ na 150℃.
4. CTBN ishobora gukoreshwa nk'ubudodo mu gusya no gukata, ifite ibyiza byo kuba ikoze mu buryo buke ariko ikagira ubushobozi bwo kudashwanyagurika, ndetse no gukora neza mu gusiga no mu mazi ashyushye.
5. CTBN ikoreshwa cyane cyane nk'igikoresho cyo gufatanya n'ibinyabiziga bikomeye bya roketi.
6. CTBN yo gusiga (umuti, ifu, amazi).
7. N'ubundi bwoko bwinshi bw'imikoreshereze
Ipakiye mu 50kg/ingoma, 180kg/ingoma, Igihe cyo kubika ni umwaka 1.
Amabwiriza y'umutekano:
Ububiko bugomba kuba ahantu hakonje, humutse kandi hahumeka umwuka. Uburyo bwiza ni hagati ya -20 ~ 38℃. Igihe cyo kubika ni amezi 12, niba kirangiye, kigomba gukoreshwa niba kijyanye n'igihe cyo kongera kugerageza. Iyo gutwara bigomba kwirinda imvura, izuba n'izuba. Ntukavange n'umuti ukomeye wo kugabanya ubushyuhe.
