I-CAS 69102-90-5 HTPB ipropellant eqinileyo I-Hydroxyl-terinated polybutadiene HTPB ye-propellant, i-adhesive, sealant

I-HTPB lulwelo olukude lwepolymer, irabha engamanzi entsha. Iipropati ziyahluka ngenxa yokuba i-HTPB ngumxube kunekhompawundi esulungekileyo, kwaye yenziwe ukuhlangabezana neemfuno ezithile zabathengi. I-HTPB eqhelekileyo yi-R-45M kunye nesiphelo ngasinye setsheyini epheliswe nge-hydroxyl [OH] iqela. (I-PS: sinokwenza naziphi na iinguqulelo ze-HTPB njengoko abathengi becela, kunye noyilo olutsha lwe-HTPB kunye nekhonkco elilodwa le-hydroxyl -OH, Okwangoku, sinokwenza i-hydrogenation ye-HTPB)

Yona kunye ne-agent yokwandisa ikhonkco, i-agent edibanisayo kwiqondo lokushisa okanye ukushisa okuphezulu kunokuvelisa i-3D isakhiwo sothungelwano lokunyanga umxholo.Umxholo wokunyanga uneempawu ezibalaseleyo zoomatshini, ngokukodwa ukuxhathisa okulungileyo kwi-hydrolysis, i-asidi kunye ne-alkali ukumelana, ukumelana nokunxiba, ukumelana nobushushu obuphantsi kunye ukugquma kombane okugqwesileyo.

Iipolyurethanes ezilungiselelwe ukusuka kwi-HTPB zinokuqulunqwa kwiimpawu ezithile zomzimba; I-polyurethanes inokuba nelastiki ephezulu okanye yomelele kwaye yomelele. Ezinye iimveliso zibandakanya: iipaneli eziqinileyo zokugquma amagwebu; amavili e-elastomeric ahlala ixesha elide kunye namavili (asetyenziselwa i-roller coasters, i-escalators, i-skateboards, njl.); iibhasi zokumisa iimoto; iikhompawundi zeembiza zombane; izinto zokuncamathelisa eziphezulu; iingubo ezingaphezulu kunye nezitywini eziphezulu; iintsinga zokwenziwa (umz., Spandex); ikhaphethi yangaphantsi; iindawo eziqinileyo zeplastiki (umz., izixhobo zombane).

Usetyenziso olubalulekileyo lwe-HTPB lukwi-rocket propellant eyomeleleyo. Ibophelela i-agent e-oxidizing, i-fuel kunye nezinye izithako zibe bubunzima kodwa obunwebekayo kwiinkqubo ezininzi ze-propellant. I-polyurethane enyangisiweyo isebenza njengesibaso kwimixube enjalo. Ngokomzekelo i-propellant njenge "HTPB / AP / Al = 12/68/20", oku kuthetha ukuba, ngokulinganayo ngobunzima, i-HTPB kunye nonyango lwe-12% (i-binder kunye ne-fuel), i-ammonium perchlorate 68% (oxidizer), kunye ne-aluminium powder 20% (amafutha).

Iipropellants ezifanayo, ezidla ngokubizwa ngokuba yi-APCP (i-ammonium perchlorate composite propellant) zisetyenziswa kwiirokethi ezinkulu zemodeli. I-APCP eqhelekileyo ivelisa amaxesha angama-2-3 impembelelo ethile yomgubo omnyama osetyenziswa kwiinjini ezincinci zerokethi.

I-HTPB ikwasetyenziswa njengamafutha e-rocket exutyiweyo.
