Si3N4 seramiiki bọọlụ

Silicon nitride seramiiki bọọlụ nwee ike dị elu, nguzogide akwa akwa, nguzogide okpomọkụ dị elu, nguzogide corrosion, acid na alkali resistance, enwere ike iji ya mee ogologo oge na mmiri mmiri, ma nwee ezigbo mkpuchi mkpuchi. Nwere ike ịnagide ojiji dị mgbagwoju anya na gburugburu ebe ọrụ.

Si3N4 seramiiki bọọlụ nwee oke obi na ịdị arọ. Mgbe ejiri ya na ọtụtụ ngwa ma ọ bụ akụrụngwa, ha nwere obere ọnụọgụ nke esemokwu na ike ndọda, na-eme ka ọ ghara ịda ma na-agbatị ndụ ọrụ nke ngwa.

Si3N4 seramiiki bọọlụ na-eguzogide ọgwụ dị elu ma nwee ike ịrụ ọrụ nke ọma na gburugburu ebe dị elu n'okpuru 1200 Celsius na obere mgbanwe olu. Performancerụ ọrụ ọma ji arụ ọrụ nke ọma, ikuku ịma jijiji bụ 900-1000 Celsius.

O nwekwara ihe na-etinye onwe ya mmanụ ma nwee ike iji ya mee ihe na gburugburu ebe ọ na-enweghị mmanụ na-emetọ emetọ. Ghọọ ihe a họọrọ maka seramiiki biarin na ngwakọ seramiiki bọl biarin.

E jiri ya tụnyere bọọlụ nchara, isi uru nke seramiiki bọọlụ bụ:

(1) Ọ dị 59% ọkụ karịa nchara bọọlụ, nke na-ebelata ike centrifugal, na-agbagharị na abrasion na ọsọ ọsọ mgbe eburu na-agba ọsọ ọsọ ọsọ;

(2) Modulu nke elasticity bụ 44% buru ibu karịa nke nchara, nke pụtara na oke nrụrụ dị obere karịa nke bọọlụ nchara mgbe edobere ya n'ike;

(3) Isi ike dị elu karịa nchara, HRC ruru 78;

(4) ọnụọgụ nke esemokwu bụ obere, na-enweghị magnetik, eletrik na-ekpuchi ya, ma na-eguzogide ọgwụ na-emebi ọgwụ karịa nchara;

(5) Ọnụ ọnụọgụ nke mmụba ọkụ bụ 1/4 nke ígwè, nke nwere ike iguzogide mgbanwe okpomọkụ na mberede;

(6) Ọgwụgwụ elu dị mma, Ra nwere ike iru 4-6 nanometers;

(7) Nguzogide okpomọkụ dị elu, seramiiki bọọlụ ka nwere nnukwu ike na ike na 1050 Celsius Celsius;

(8) Ọ gaghị ajari na ike na-arụ ọrụ n'okpuru mmanụ-free mmanu ọnọdụ.
