Nā kinipōpō pālolo Si3N4

Nā pōpō pālolo silikone nitride he ikaika kiʻekiʻe, pale pale kiʻekiʻe, pale mahana wela kiʻekiʻe, kūpaʻa kūpale, ʻākika a me alkali kūʻē, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i ka wai kai, a he maikaʻi nā waiwai hoʻoweliweli. Hiki iā ia ke pale me ka hoʻohana paʻakikī a me ke ʻano hana.

Nā kinipōpō pālolo Si3N4 loaʻa ka paʻakikī kiʻekiʻe a me ke kaupaona māmā. Ke hoʻohana ʻia i nā mea kikoʻī a me nā lakohana ʻokoʻa, loaʻa iā lākou kahi koina liʻiliʻi o ka hakina a me ka wikiwiki o ka umekaumaha, e hopena ana i ka liʻiliʻi o ka lole a hoʻonui i ke ola lawelawe o nā mea kōkua.

Nā kinipōpō pālolo Si3N4 kūpaʻa i nā mahana wela a hiki ke hana paʻa i kahi wahi wela kiʻekiʻe ma lalo o 1200 kekelē Celsius me nā loli liʻiliʻi. ʻOi aku ka maikaʻi o ka haʻalulu hoʻomehana, ʻo 900-1000 kekelē Celsius.

Loaʻa iā ia nā waiwai lubricating ponoʻī a hiki ke hoʻohana ʻia i nā wahi kahi i hoʻohaumia ʻole ʻia kahi mea lubricating. Lilo i ka mea o ke koho no ka pālolo bearings a me ka hapalua pālolo poepoe nā mea pilihao.

Hoʻohālikelike ʻia me nā pōpō kila, nā mea nui o nā pōpō pālolo:

(1) ʻoi aku ka māmā o 59% ma mua o nā kinipōpō kila, kahi e hoʻēmi ai i ka ikaika centrifugal, e kaʻa ana a me ka abrasion ma ke ala heihei ke holo nei ka mea nui i ka wikiwiki;

(2) ʻO ka modulus o ka elasticity he 44% ʻoi aku ka nui ma mua o ka hao, ʻo ia hoʻi ka liʻiliʻi o ka nui o ka deformation ma mua o nā pōpō kila ke hoʻokau ʻia i ka ikaika;

(3) ʻOi aku ka paʻakikī ma mua o ke kila, HRC hiki i 78;

(4) Heʻuʻuku ka coefficient o ka hakakā, non-magnet, insulated uila, a ʻoi aku ka pale aku i ka popopo ʻino ma mua o ke kila;

(5) Ke kolamu o ka hoʻonui hoʻonui ʻana he 1/4 o ke kila, i hiki ke kū i nā hoʻololi wela koke;

(6) ʻOi aku ka maikaʻi o ka hoʻopau o ka papa, Ra hiki i 4-6 nanometers;

(7) Ke kū wela wela kiʻekiʻe, ʻo ka ikaika a me ka paʻakikī ka pōpō pālolo ma 1050 kekelē Celsius;

(8) ʻAʻole e pala a hiki ke hana ma lalo o nā kūlana lubrication ʻaʻohe aila.
