Kev Txhim Kho Kev Tsim Khoom ntawm HTPB, CTBN thiab DDI (Dimeryl Diisocyanate)
Yog dab tsi HTPB ?
HTPB kuj hu ua hydroxyl-terminated polybutadiene (CAS No. 69102-90-5), yog cov roj hmab tshiab (resin), HTPB muaj cov pab pawg hyroxyl uas muaj zog. Nws tuaj yeem ua rau muaj kev cuam tshuam nrog tus neeg sawv cev txuas ntxiv, tus neeg sawv cev sib txuas hauv chav tsev kub lossis kub siab los tsim cov qauv network 3D ntawm kev kho cov ntsiab lus uas muaj cov khoom siv kho tshuab zoo heev.
Cov khoom ua tau zoo ntawm HTPB xws li: Hydrophobicity, Reactive hyroxyl pawg, Qis iav hloov pauv kub, Qis xim - siab viscous kua, Tsis kam rau hydrolysis,
Tsis tshua muaj kev kub thiab txias, Tsis tshua muaj dej noo permeability, Tsis kam rau cov kua qaub thiab cov hauv paus aqueous, Muaj zog hnav tsis kam, Zoo heev adhesion rau ntau yam substrates, Hluav taws xob rwb thaiv tsev zog, Zoo heev mechanical zog ua rau nws dav siv hauv:
- Cov txheej txheem
- Cov nplaum
- Cov roj av
- Cov ntaub ntawv Polyurethane (PU)
- Cov ntawv khi
- Cov tshuaj nplaum
- Cov ntaub ntawv rwb thaiv tsev hluav taws xob
- Cov khoom siv roj hmab
- Cov ntaub ntawv siv hauv tsheb thiab dav hlau
- Cov ntaub ntawv siv hauv tsev (tsis pub dej nkag, tiv thaiv xeb, rwb thaiv tshav kub)
- Kev ntim khoom thiab encapsulation
- Kev Hloov Kho Polymer
- thiab ntau lwm yam kev siv.
Yog dab tsi CTBN ?
CTBN kuj paub tias carboxyl-terminated butadiene-acrylonitrile copolymer (CAS No. 25265-19-4 lossis 68891-46-3), pawg carboxyl ua nws pawg ua haujlwm, tuaj yeem siv dav hauv kev tsav dav hlau thiab thaj chaw kev lag luam pej xeem. Vim yog pawg carboxyl-terminated ua rau nws tuaj yeem cuam tshuam nrog epoxy resin los txhim kho qhov tawv.
Cov yam ntxwv ntawm CTBN li: Txhim kho qhov tawv thiab yooj ywm ntawm thermoset resins, Txhim kho kev nplaum rau cov substrates uas nyuaj rau kev sib txuas, Ua kom muaj kev cuam tshuam thiab tawg tsis kam, Txhim kho kev ruaj khov (kev qaug zog tsis kam), Ua kom cov khoom siv kho tshuab qis-kub, thiab lwm yam ua rau nws siv dav hauv:
1. Cov nplaum, kev sib txuas, kev kaw, kev txau, kev cog qoob loo (aerospace, automotive, electrical/electronics, industrial, marine thiab construction applications..)
2. Cov txheej txheem (kua, hmoov, dej ntws)
3. CTBN yog lub zog rau epoxy resin, thiab yog ib qho kev hloov pauv zoo heev rau cov thermosetting resins xws li epoxy, phenolic, unsaturated polyester thiab photosensitive resins.
Yog dab tsi TSIS MUAJ ?
TSIS MUAJ kuj paub tias Dimeryl Diisocyanate CAS No. 68239-06-5, DDI yog ib qho tshwj xeeb aliphatic diisocyanate uas siv tau los npaj cov polymers nrog cov tshuaj uas muaj cov hydrogen nquag. Nws yog ib qho tshuaj ntev nrog 36-carbon dimer fatty acid backbone. Cov qauv tseem ceeb ntawm cov saw hlau muab DDI qhov yooj ywm zoo dua, tiv taus dej thiab tsis muaj tshuaj lom rau lwm cov aliphatic isocyanates. DDI yog cov kua viscosity qis uas yooj yim yaj hauv feem ntau cov kuab tshuaj polar lossis tsis-polar. Vim tias nws yog aliphatic isocyanate, muaj cov yam ntxwv ntawm tsis daj. Nws muaj ntau qhov zoo ntawm kev lom tsawg, yooj yim siv, yaj hauv feem ntau cov kuab tshuaj, lub sijhawm tshuaj tiv thaiv tswj tau thiab tsis muaj dej rhiab heev. Nws yog ib qho tshwj xeeb biorenewable ntsuab isocyanate ntau yam, uas tuaj yeem siv dav hauv cov ntaub tiav, elastomers, adhesives thiab sealants, coatings, inks thiab lwm yam tub rog thiab civil teb.
Peb tau ua kom zoo dua qhov kev tsim khoom ntawm HTPB, CTBN thiab DDI (Dimeryl Diisocyanate) kom txhim kho lawv cov kev ua tau zoo, thiab ua rau cov nqi sib tw ntau dua piv rau Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
