PBO isitaple ifayibha Umfanekiso obonakalayo

PBO isitaple fiber

Inkcazelo emfutshane:

Thatha i-PBO filament njengento ekrwada, yayikrwada, yamiliselwa, yasikwa zizixhobo zobuchwephesha. Uphawu lobushushu obuxhathisayo kwiqondo le-600, kunye ne-spunability elungileyo, ukumelana nokusika, esetyenziswa ngokubanzi kwimimandla yelaphu elikhethekileyo lobuchwephesha, iimpahla zokuhlangula umlilo, ibhanti lokucoca ubushushu obuphezulu, ibhanti lokumelana nobushushu, i-aluminiyamu kunye nezinto ezithintela ubushushu. (ukulungiswa kweglasi).

PBO isitaple fiber

Thatha i-PBO filament njengento ekrwada, yayikrwada, yamiliselwa, yasikwa zizixhobo zobuchwephesha. Isici sokumelana nobushushu be-600 degree, kunye ne-spunability efanelekileyo, ukuxhathisa ukusika, esetyenziswa ngokubanzi kwiinkalo zelaphu elikhethekileyo lobugcisa, iimpahla zokuhlangula umlilo, ibhanti lokucoca ubushushu obuphezulu, ibhanti lokumelana nobushushu, i-aluminium kunye nezinto ezithintela ukushisa (ukulungiswa kweglasi) .

I-PBO, ye-poly(p-phenylene-2,6-benzobisoxazole)

I-PBO, ye-poly(p-phenylene-2,6-benzobisoxazole) yinto ekhethekileyo kwiintsinga ezinomatshini ophezulu kunye nokusebenza kwe-thermal.
Iimpawu zayo zomatshini zingaphezulu kwefayibha ye-aramid, kunye nezibonelelo zemodyuli ephezulu ephezulu, ifayibha ye-PBO ine-retardant ebalaseleyo yomlilo kunye nokumelana ne-thermal yayo (iqondo lobushushu: 650 ° C, ubushushu bokusebenza 350 ° C-400 ° C), itultra- ilahleko ye-dielectric ephantsi, ukuhanjiswa kunye nokukwazi ukusonta ukukhanya, ifayibha ye-PBO inamathuba amaninzi okusebenza kwi-aerospace, ukhuselo lwelizwe, amapolisa kunye nezixhobo zokulwa nomlilo, ukuhamba ngololiwe, unxibelelwano lwe-elektroniki kunye nokhuseleko loluntu.
Yenye yezona zinto zixhaphakileyo zisetyenziswa kabini kwizixhobo zobuchule kuluntu lwangoku.

Yintoni esiyenzayo nge-PBO staple fiber

Weinikeza uluhlu olubanzi lweubuchwephesheImisonto enePBO esulungekileyo okanye edityaniswe nezinye izinto. Ngokuxhomekeke kwingxaki, siya kukucebisa malunga nohlobo lomsonto, ubunjani befiber exutywe ne-PBO (i-aramid, insimbi engenasici, njl. njl.) kunye nobukhulu bomsonto. Le misonto inokudityaniswa kumanqaku alukiweyo, aphothiweyo okanye athungiweyo xa uceliwe.

Isicelo

Imisonto ye-PBO esisigxina yefiber ephothiweyo inokusetyenziswa njengelaphu elingatshiyo kwimpahla yokuhlangula umlilo.
Umsonto ophothiweyo owenziwe yiPBO ifayibha enefiber yentsimbi unokulukwa iteyiphu ekwaziyo ukumelana nobushushu.
Isihluzi esinganyangekiyo se-Thermal esenziwe yi-PBO isitaple fiber evakala njalo njalo.

Ifayibha ye-PBO inokufunxa isixa esikhulu samandla empembelelo xa inefuthe, eyona nto igqwesileyo ukumelana nempembelelo. Umthwalo omkhulu wempembelelo ye-PBO ye-fiber composite inokufikelela kwi-3.5KN kunye nokuxutywa kwamandla yi-20J. Ukumelana nokunxiba kwePB0 kulungile, kwaye umjikelo wokunxiba ungamawaka amahlanu amaxesha.

I-PBO fiber kwiqondo lokushisa elingaphezulu kwe-300 ° C ingabonakalisa iimpawu ezingcono zokumelana nokunxiba, kwaye izinga layo lokugcinwa kwamandla malunga ne-45% emva kweeyure ze-100 zonyango emoyeni kwi-300 ° C.
Ilaphu le-PBO kancinane kunye nokuguquguquka kuphucule ukukhululeka kunye nokushukuma kwaye bubushushu kunye nempahla yokusebenza ekwaziyo ukumelana nomlilo.
