Hagaajinta Waxsoosaarka ee HTPB, CTBN iyo DDI (Dimeryl Diisocyanate)
Waa maxay HTPB ?
HTPB sidoo kale loo yaqaan sida Polybutadiene-ka la joojiyay hydroxyl (CAS No. 69102-90-5), waa caag dareere ah (resin) cusub, HTPB waxay leedahay kooxo hydroxyl ah oo firfircoon. Waxay ka fal celin kartaa wakiilka fidinta silsiladda, wakiilka isku xidhka heerkulka qolka ama heerkulka sare si loo soo saaro qaab-dhismeedka shabakadda 3D ee daaweynta waxyaabaha leh sifooyin farsamo oo heer sare ah.
Sifooyinka waxqabadka ee HTPB sida: Hydrophobicity, Kooxaha hyroxyl ee falcelinta leh, Heerkulka kala-guurka galaaska oo hooseeya, Midab hooseeya - dareere fiiqan oo cad, Iska caabbinta hydrolysis,
Iska caabin heerkul hooseeya, Gudbinta qoyaanka oo hooseeya, Iska caabinta asiidhyada biyaha iyo saldhigyada, Iska caabin adag oo xirasho, Ku dhegid aad u fiican oo loo sameeyo noocyo kala duwan oo substrate ah, Sifooyinka dahaarka korontada, Sifooyinka farsamada ee aadka u fiican ayaa si weyn loogu isticmaalaa:
- Dahaarka
- Xabag
- Propellants
- Agabka Polyurethane (PU)
- Xidhayaasha
- Shaabadaha
- Qalabka dahaarka korontada
- Alaabada caagga ah
- Qalabka dhismaha ee baabuurta iyo diyaaradaha
- Qalabka dhismaha (biyo-celin, ka hortagga daxalka, dahaarka kulaylka)
- Dheriga iyo buuxinta
- Wax ka beddelka Polymer-ka
- iyo noocyo kale oo badan oo la isticmaalo.
Waa maxay CTBN ?
CTBN sidoo kale loo yaqaan sida copolymer-ka butadiene-acrylonitrile ee la joojiyay karboksil ( CAS No. 25265-19-4 ama 68891-46-3)Kooxda carboxyl-ka oo ah kooxda shaqada, waxaa guud ahaan loo isticmaali karaa duulista hawada iyo warshadaha madaniga ah. Sababtoo ah kooxda firfircoon ee la joojiyay carboxy-ka, waxay ka fal celin kartaa resin epoxy si ay u xoojiso adkeysiga.
Sifooyinka CTBN sida: Waxay xoojisaa adkeysiga iyo dabacsanaanta resins-ka thermoset-ka, Waxay hagaajisaa dhegdhegga substrate-yada ay adag tahay in la isku xidho, Waxay kordhisaa iska caabbinta saameynta iyo dildilaaca, Waxay hagaajisaa adkeysiga (iska caabbinta daalka), Waxay kordhisaa sifooyinka farsamada heerkulka hooseeya, iwm. Waxay ka dhigtaa mid si ballaaran loogu isticmaalo:
1. Xabag, isku xidh, shaabad, buufin, dheri-sameyn (aerospace, baabuurta, korontada/elektarooniga, warshadaha, codsiyada badda iyo dhismaha..)
2. Dahaarka (xalka, budada, biyaha laga soo qaado)
3. CTBN waa adkaysi u leh resin epoxy, waana wax ka beddel dabacsanaan aad u fiican resins-ka thermosetting sida epoxy, phenolic, polyester-ka aan buuxin iyo resins-ka xasaasiga ah.
Waa maxay MAYA ?
MAYA sidoo kale loo yaqaan sida Dimeryl Diisocyanate CAS No. 68239-06-5DDI waa diisocyanate gaar ah oo loo isticmaali karo in lagu diyaariyo polymers leh iskudhisyo ay ku jiraan haydarojiin firfircoon. Waa iskudhis silsilad dheer leh oo leh laf-dhabar 36-kaarboon dimer ah oo dufan leh. Qaab-dhismeedka silsiladda ugu weyn wuxuu siinayaa DDI dabacsanaan sare, iska caabinta biyaha iyo sunta yar ee isocyanates kale ee aliphatic. DDI waa dareere viscosity hooseeya oo si fudud ugu milmi kara inta badan dareerayaasha polar ama kuwa aan polar ahayn. Sababtoo ah waa isocyanate aliphatic, waxay leedahay astaamaha aan huruud ahayn. Waxay leedahay faa'iidooyin badan oo sunta yar, fududahay in la isticmaalo, ku milma inta badan dareerayaasha, waqtiga falcelinta la xakamayn karo iyo dareenka biyaha oo hooseeya. Waa nooc isocyanate gaar ah oo cagaaran oo biorenewable ah, kaas oo si weyn loogu isticmaali karo dhammaystirka dharka, elastomers, dhejisyada iyo shaabadaha, dahaarka, khad iyo goobaha kale ee militariga iyo rayidka.
Waxaan hagaajinay soo saarista HTPBN, CTBN iyo DDI (Dimeryl Diisocyanate) si aan u horumarinno waxqabadkooda, isla markaana aan ka dhigno qiimaha mid tartan badan marka la barbar dhigo Poly BD R45 HTLO, Huntsman 1300X13 (Hypro 1300X13 CTBN).
