Umfanekiso obonisiweyo weHydrogenated Hydroxyl Group-Terminated Polybutadiene

I-Hydrogenated HTPB I-Hydrogenated Hydroxyl Group-Terminated Polybutadiene

Inkcazo emfutshane:

I-HTTPB yipolymer ye-liquid remote claw, irabha entsha yolwelo. Iimpawu zahlukile kuba i-HTPB ngumxube endaweni yokuba yi-compound ecocekileyo, kwaye yenziwe ukuze ihlangabezane neemfuno zabathengi ezithile. I-HTPB eqhelekileyo yi-R-45M apho isiphelo ngasinye sekhonkco sipheliswe liqela le-hydroxyl [OH]. (PS: singenza uyilo olutsha njenge-HTPB ene-single -OH ngekhonkco kunye ne-Hydrogenated version).

Iimbonakalo

I-HTPB yipolymer ye-claw ekude yolwelo, irabha entsha yolwelo. Iimpawu zahlukile kuba i-HTPB ngumxube endaweni yokuba yi-compound ecocekileyo, kwaye yenziwe ukuze ihlangabezane neemfuno ezithile zabathengi. I-HTPB eqhelekileyo yi-R-45M apho isiphelo ngasinye sekhonkco siphela ngeqela le-hydroxyl [OH].PS: singenza naziphi na iinguqulelo ze-HTPB njengoko abathengi becela, kwaye siyile i-HTPB entsha ngomxokelelwane omnye we-hydroxyl -OH, Okwangoku, singenza i-hydrogenation ye-HTPB)

Kwi-Hydrogenated HTPB kukho ii-hydrogenated homopolymers ze-butadiene, zipheliswe zombini ii-hydroxyl group kwaye zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Ngenxa yokugcwala kwe-1,2-vinyl group ezi polybutadienes zinozinzo oluhle kakhulu lweekhemikhali oluhlala ixesha elide.

Iipropati ezinje:

Isakhiwo esiguquguquka kakhulu

Ukungathandi amanzi

I-constant ye-dielectric ephantsi

Ukumelana kakuhle kweekhemikhali

Amaqela e-hydroxyl asebenzayo

Uzinzo lwexesha elide

Izicelo

Izilungisi ze-resin, ii-urethane resins (iipeyinti, izincamathelisi, ii-coating agents), izixhobo zombane zokukhusela, ii-TPU elastomers

Ukupakisha kunye nokugcina

Ukupakisha:

Ipakishwe kwi-50kg/drum, i-170kg/drum, ixesha lokugcina liyi-1 ngonyaka.

Imiyalelo yokhuseleko:

Indawo yokugcina kufuneka ibe kwindawo epholileyo, eyomileyo kwaye iphefumle umoya. Imeko engcono iphakathi kwe -20 ~ 38℃. Ixesha lokugcinwa kweshelufu leenyanga ezili-12, ukuba liphelile, lingasetyenziswa ukuba lisemgangathweni xa livavanywa kwakhona. Xa uthutho kufuneka uphephe imvula, ukukhanya kwelanga. Musa ukuxuba ne-oxidizer enamandla.
