He aha ka mea i hana ʻia ai ka ʻōpala?
Nā mea
Wolfram carbide
ʻO Tungsten carbide kahi hui i hui ʻia me 50% tungsten a me 50% carbon. Nui nā ʻano hana i hoʻohana ʻia e hana i ka pūhui, ʻo ka mea maʻamau ʻo ia ka pilina o ka tungsten metala me ke kalapona ma kahi mahana o 1400 a 2000 ° C. kekelē Celsius.ʻO nā kila māmā wikiwiki
ʻO ke kila māmā kiʻekiʻe (HSS) he mea hoʻohui e hui pū i ke kila (hao a me ke kalapona) me nā mea ʻē aʻe e like me chromium, molybdenum, tungsten, vanadium a i ʻole cobalt. Hiki i nā mea ʻē aʻe ma mua o ke kila ke hana i ka 20% o ka haku mele HSS, akā ʻoi aku ma mua o 7%.ʻO ka hoʻohui ʻana i kēia mau mea i ke kila ʻaʻole ia e hana i ka HSS, pono e hoʻomaʻamaʻa ʻia ka mea i ka wela a me ka huhū.
Hiki i ke kila māmā kiʻekiʻe (HSS) ke ʻoki i nā mea i ʻoi aku ka wikiwiki ma mua o ke kila kalapona kiʻekiʻe, no laila ka inoa ʻo "high speed". ʻO kēia ma muli o kona ʻoi aku ka paʻakikī a me ke kūpaʻa abrasion i hoʻohālikelike ʻia me ke kalapona kiʻekiʻe a me nā mea hana ʻē aʻe.
No ke aha i hoʻohana ʻia ai ke kila māmā a me ka carbide no nā ʻōpala scraper?
Pono e hana ʻia ka ʻili ʻōpala me kahi mea ʻoi aku ka paʻakikī ma mua o ka mea e ʻoki ʻia ana i mea e pono ai. ʻO nā mea hoʻohui hou a me nā kaʻina hana hana, e like me ka mālama wela i hoʻokau ʻia i ke kila wikiwiki, e hāʻawi i ka paʻakikī e pono ai no ka ʻoki ʻana.
ʻOi aku ka paʻakikī o nā ʻōpala Carbide ma mua o ka HSS. ʻAe kēia iā lākou e hoʻohana ʻia ma kahi ākea ākea o nā mea.
ʻAʻole hiki ke hoʻololi ʻia nā ʻōpala scraper
ʻAʻole hiki ke hoʻololi hou ʻia nā ʻāpana scraper ʻaneʻane i hana ʻia me ke kila māmā, ʻoiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai no ka hana ʻana i ka lau a me ke kumu mai ka carbide.ʻOiai ua hana ʻia nā ʻāpana ʻōpala hiki ʻole ke hoʻololi ʻia i ke kila wikiwiki, ʻo kahi hapa liʻiliʻi wale nō ma ka hope o ka scraper e mālama ʻia a wela. ʻOkoʻa pinepine ka waihoʻoluʻu o ka wahi i mālama ʻia me ka wela mai ke koena o ka lāʻau.
He aha nā mea e hiki ke hoʻohana ʻia i nā ʻōpala scraper?
