Kugadziriswa kweHTPB: Kushanda uye Kushandiswa

Kubviswa kweHTPB muropa: Kushanda uye Mashandisirwo

Polybutadiene yakagumiswa nehydroxyl (HTPB) ipolymer inoshanda zvakasiyana-siyana inozivikanwa nehunyanzvi hwayo hwemakanika, tembiricha yakaderera yekuchinja kwegirazi,

uye kuramba zvakanyanya kumakemikari uye mamiriro ekunze. Imwe yenzira huru mukugadzirisa HTPB kuti iwedzere hunhu hwayo ndeye epoxidation.

yeHTPB inosanganisira kuwedzerwa kwemapoka epoxide kumusana wepolymer, zvichikonzera kuti chinhu chakagadziriswa chine hunhu hwakanaka hwekushanda.

Chinyorwa chino chinoongorora epoxidation yeHTPB, mashandiro ayo, uye mashandisirwo ayo muzvishandiso zvakasiyana-siyana.

Iyo epoxidation yehydroxyl-terminated polybutadiene (HTPB) idanho rakakosha mukugadzirwa kwezvinhu zvepamusoro zvine hunhu hwakawedzerwa.

Maitiro acho anosanganisira kuita kweHTPB nemushonga unopoxidiza, senge peracetic acid kana hydrogen peroxide, kuti uunze mapoka epoxide pamwe chete.

cheni yepolymer. Kugadziriswa uku kunoita kuti HTPB isakwanise kushandiswa nemakemikari, kunamatira, uye kugadzikana kwekupisa, zvichiita kuti ive yakakodzera kushandiswa kwemhando dzakasiyana dze

mhando dzakasiyana dzemashandisirwo.

Chimwe chezvakanakira zvakakosha zvekushanda kwe HTPB yakasanganiswa ne epoxidized ndiyo hunhu hwayo hwekunamatira hwakanyanya. Kuunzwa kwemapoka epoxide kunowedzera kuenderana

yeHTPB ine zvinhu zvakasiyana-siyana, zvichiita kuti kunamira kwacho kuve nani mukushandisa kweglue nesealant. Pamusoro pezvo, HTPB yakasanganiswa ne epoxidized inoratidza kusimba kwakanaka

kuzvinhu zvinonyungudutsa, mafuta, uye mafuta, zvichiita kuti ive sarudzo yakakodzera yekuputira, kunamira, uye zvinonamira munzvimbo dzinoda kushanda nesimba.

Uyezve, kubudiswa kweHTPB Kuvapo kwemapoka e epoxide kunoita kuti kupisa kuve kwakasimba uye kuti moto usashande zvakanaka.

Kudzivirira kupisa nemurazvo, zvichiita kuti zvikwanise kushandiswa mundege, mota, uye kuvaka uko kuchengetedzeka pamoto kuri chinhu chakakosha kufunga nezvacho.

Pamusoro pezvo, HTPB yakasanganiswa ne epoxidized inogona kushandiswa se binder mukugadzira zvinhu zvine simba repamusoro, zvichipa hunhu hwemakanika hwakavandudzwa

uye kugara kwenguva refu.

Panyaya yekushandiswa, HTPB yakasanganiswa ne epoxidized inowana mashandisirwo mumaindasitiri akasiyana-siyana. Muchikamu chezvendege, inoshandiswa mukugadzira manamati,

zvinhu zvinosanganisa muhari, uye zvinonamira zvekubatanidza nekusimbisa zvinhu zvakakosha. Kunamatira kwayo kwakanaka uye kuramba makemikari kunoita kuti ive sarudzo yakanaka kune

mashandisirwo emuchadenga uko kuvimbika uye mashandiro zviri zvinhu zvakakosha.

Uyezve, muindasitiri yemotokari, HTPB yakasanganiswa ne epoxidized inoshandiswa mukugadzira machira, ma sealant, uye ma encapsulants ezvikamu zvemagetsi uye

kushandiswa kwayo pasi pehood. Kukwanisa kwayo kutsungirira kusvibiswa kwemotokari nemamiriro ekunze kunoita kuti ive chinhu chinodiwa pakushandisa mota

zvikumbiro zvekuvhara nekudzivirira.

Pamusoro pezvo, HTPB yakasanganiswa ne epoxidized Inoshandiswa muindasitiri yekuvaka kugadzira machira epamusoro-soro, manamati, uye zvinonamira zvekuvaka,

mashandisirwo ayo mumaindasitiri, uye muzvivakwa. Kubatana kwayo kwakanyanya, kuchinjika kwayo mumamiriro ekunze, uye kusabatwa nemakemikari zvinoita kuti ive chinhu chinokosha chekudzivirira nekusimudzira

kugara kwenguva refu kwezvinhu zvekuvaka.

Mukupedzisa, kubudiswa kweHTPB zvinoguma nechinhu chakagadziriswa chine hunhu hwekushanda hwakavandudzwa, zvichiita kuti chikodzere kushandiswa kwakasiyana-siyana

muindasitiri dzakasiyana-siyana. Kunamira kuri nani, kuramba makemikari, kugadzikana kwekupisa, uye kunonoka kwemurazvo weHTPB yakasanganiswa ne epoxid kunoita kuti ive chinhu chinokosha kune

kugadzira machira epamusoro, zvinonamira, zvinonamira, uye zvinhu zvakasanganiswa. Sezvo tsvakiridzo nekuvandudzwa kwekugadzirisa mapolymer zvichiramba zvichifambira mberi,

HTPB yakasanganiswa ne epoxidized inotarisirwa kuita basa guru mukugadzirwa kwezvinhu zvinoshanda zvakanyanya zvemaindasitiri akasiyana-siyana.

Tinopa mhando dzakasiyana dze HTTPB, kubudiswa kweHTPB, HTPB yeboka reHydroxyl rimwe chete, HTPB ine Hydrogenated...
