Kunoza umusaruro wa HTPB, CTBN na DDI (Dimeryl Diisocyanate)
Ni iki HTTPB ?
HTTPB izwi kandi nka Polybutadiene ivanyweho na hydroxyl (CAS No. 69102-90-5), ni resin nshya y'amazi (resin), HTPB ifite amatsinda ya hyroxyl arwanya imihindagurikire y'ikirere. Ishobora gukorana n'umuyoboro w'amashanyarazi, umuyoboro uhuza ibintu mu bushyuhe bw'icyumba cyangwa ubushyuhe bwinshi kugira ngo ikore imiterere ya 3D y'umuyoboro w'amashanyarazi ufite imiterere myiza ya mekanike.
Imiterere y'imikorere ya HTPB ni: Hydrophobicity, Reactive hyroxyl groups, Ubushyuhe buke bw'impinduka mu kirahuri, Ibara rike - amazi afite ibara ryinshi, Ubudahangarwa na hydrolysis,
Irwanya ubushyuhe buke, Ishobora kunyura mu mazi make, Irwanya aside n'ibice by'amazi, Irwanya kwangirika gukomeye, Ifata neza ibintu bitandukanye, Ituma amashanyarazi akingira, Ituma ikoreshwa cyane muri:
- Amarangi
- Ibikoresho bikonjesha
- Ibikoresho bitera umuyaga
- Ibikoresho bya Polyurethane (PU)
- Ibikoresho byo gufunga
- Ibifunga
- Ibikoresho by'amashanyarazi bikingira
- Ibikoresho bya Rubber
- Ibikoresho by'ubwubatsi mu modoka no mu ndege
- Ibikoresho by'ubwubatsi (birinda amazi, birwanya ingese, bikingira ubushyuhe)
- Gushyira mu nkono no gufunga
- Ihinduka rya polimeri
- n'ubundi bwoko bwinshi bw'imikoreshereze.
Ni iki CTBN ?
CTBN kandi azi nka Kopolymer ya butadiene-acrylonitrile ivanyweho na karboksili (Nomero ya CAS 25265-19-4 cyangwa 68891-46-3), itsinda rya karubokisili nk'itsinda ry'imikorere yaryo, rishobora gukoreshwa muri rusange mu ndege no mu nganda za leta. Kubera itsinda rikora rya karubokisili rituma rishobora gukorana na resin ya epoxy kugira ngo ryongere ubukana.
Ibiranga CTBN ni: Yongera ubukomere n'ubushobozi bwo koroha bwa thermoset resins, Yongera uburyo bwo gufatana n'ibintu bigoye gufatana na byo, Yongera imbaraga n'ubudahangarwa, Yongera uburambe (ubudahangarwa bw'umunaniro), Yongera imiterere y'ubushyuhe buke, n'ibindi bituma ikoreshwa cyane muri:
1. Kole, gufatanya, gufunga, gutera, gusya (ikirere, imodoka, amashanyarazi/ibikoresho by'ikoranabuhanga, inganda, amazi yo mu mazi n'ubwubatsi).
2. Irangi (umuti, ifu, amazi)
3. CTBN ni ubukomere bwa epoxy resin, kandi ni uburyo bwiza bwo guhindura ubworoherane bwa resin zikoresha thermosetting nka epoxy, phenolic, polyester idafite ubushyuhe n'izikoresha fotosensi.
Ni iki OYA ?
OYA kandi azi nka Dimeryl Diisocyanate CAS No 68239-06-5, DDI ni diisocyanate yihariye ya aliphatic ishobora gukoreshwa mu gutegura polymeri hamwe n'ibintu birimo hydrogen ikora. Ni imvange y'umugozi muremure ifite umugongo wa aside fatty ya 36-dimer dimer. Imiterere y'uruhererekane nyamukuru ituma DDI irushaho koroha, irwanya amazi kandi ikaba nke ku zindi isocyanate za aliphatic. DDI ni amazi afite viscosity nkeya ashobora gushonga byoroshye mu bintu byinshi bya polar cyangwa bitari polar. Kubera ko ari isocyanate ya aliphatic, ifite imiterere yo kudahinduka umuhondo. Ifite ibyiza byinshi byo kuba uburozi buke, byoroshye gukoresha, ishonga mu bintu byinshi bya polar, igihe cyo kugenzurwa no kuba nta bushobozi bwo kumva amazi. Ni ubwoko busanzwe bwa isocyanate yihariye y'icyatsi kibisi ishobora kuvugururwa, ishobora gukoreshwa cyane mu kurangiza imyenda, elastomers, kole n'ibifunga, irangi, irangi n'ibindi bikorwa bya gisirikare n'ibya gisivili.
Twanogeje umusaruro wa HTPB, CTBN na DDI (Dimeryl Diisocyanate) kugira ngo twongere imikorere yabyo, kandi turusheho gutuma ibiciro birushaho gupiganwa ugereranije na Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
