ʻO nā pahi Carbide i hoʻohana ʻia i ka ʻoki ʻana i ka hana lāʻau he mau ʻāpana, e like me ka circular saw blades, strip band saws, milling cutters, profiling knives, etc. ʻoki lāʻau, a ʻo ka carbiade cemented e pili ana no ka ʻoki ʻana i nā mea like ʻole ma lalo nei. Ma lalo iho nei ka papa inoa o nā carbides i hoʻopaʻa ʻia e pili ana i nā ʻoki mea like ʻole.

1. ʻO ka papa ʻāpana, ka papa haʻahaʻa, a me ka chipboard ʻO kēia mau papa i hoʻohui ʻia e ka lāʻau, ke kāpili kemika, a me nā panela melamine. ʻO kona mau hiʻohiʻona ʻo ia ka paʻakikī o ka veneer, he kiʻekiʻe ke kiʻekiʻe o ka papa o loko a aia kekahi. hapa o na haumia paakiki. I ka wā o ka ʻoki ʻana, he koi koʻikoʻi ka hale hana hale i ka burr o ka ʻāpana ʻoki, no laila e koho pinepine nā papa lāʻau i ka carbide cemented me ka paʻakikī Rockwell o 93.5-95 degere. ʻO ka mea o ka alloy ke koho nui i ka tungsten carbide me ka nui o ka palaoa ma lalo o 0.8 um a me ka haʻahaʻa haʻahaʻa o ka pae binder. I nā makahiki i hala iho nei, ma muli o ka hoʻololi ʻana a me ka hoʻololi ʻana o nā mea waiwai, ua koho mālie nā hale ʻoihana lako i nā ʻili daimana composite ma mua o nā pahi ʻike carbide no ka ʻoki ʻana i nā ʻoki ʻoki uila. ʻOi aku ka paʻakikī o ka daimana Composite, a ʻoi aku ka maikaʻi o kona adhesiveness a me ka corrosion resistance i ka carbide cemented i ke kaʻina o ka ʻoki ʻana i ka lāʻau. E like me ka ʻokiʻoki ʻana i nā ʻikepili hana, ʻo ke ola lawelawe o ka ʻili daimana composite ma kahi o 15 mau manawa o ka lāʻau carbiade cemented saw blade.

2. ʻO ka lāʻau paʻa ka mea nui i nā ʻano lāʻau kanu maoli. ʻAʻole like ka paʻakikī o ka ʻoki ʻana i nā lāʻau i kanu ʻia. ʻO ka hapa nui o nā hale hana pahi e koho maʻamau i nā alloys me kahi degere o 91-93.5. No ka laʻana, he paʻakikī nā ʻohe o ka ʻohe a me ka lāʻau akā he maʻalahi ka lāʻau, no laila, koho pinepine ʻia nā mea hoʻohui me ka paʻakikī ma luna o 93 degere e hōʻoia i ka ʻoi aku ka maikaʻi; ʻO nā lāʻau me ka nui o nā puʻupuʻu ʻaʻole i hoʻohālikelike ʻia i ka wā e ʻoki ai, no laila ʻo ka lau He mea maʻalahi loa ia e hana i ka ʻoki ʻana i ka wā e hālāwai ai i nā puʻupuʻu, no laila ke koho pinepine ʻia ka alloy ma waena o 92-93 degere, ʻaʻole ia e hōʻoiaʻiʻo i kahi oi akā loaʻa kekahi degere. ʻO ka pale ʻana i ka hāʻule ʻana, ʻoiai ʻo ka lāʻau me nā puʻupuʻu liʻiliʻi a me nā lāʻau like ʻole, e koho ʻia nā hui me ka paʻakikī ma luna o 93 degere. ʻOiai ka lōʻihi o ke kūpaʻa ʻana o ka ʻaʻahu kiʻekiʻe a me ka ʻoi, hiki ke ʻoki ʻia no ka manawa lōʻihi; ʻO ka lāʻau mua ma ka ʻākau e hana i ka lāʻau hau ma muli o ke anuanu loa i ka hoʻoilo, a ʻo ka lāʻau hau e hoʻonui i ka paʻakikī o ka lāʻau. Eia kekahi, ʻoi aku ka maʻalahi o ka ʻoki ʻana i nā ʻāpana lāʻau maloʻo i nā wahi anuanu loa, no laila, i kēia hihia, koho pinepine ʻia nā ʻāpana me kahi mahana o 88-90 degere no ka ʻoki ʻana.

3. Laau haumia. He nui nā haumia o kēia ʻano lāʻau. No ka laʻana, ʻo nā papa i hoʻohana ʻia i nā kahua kūkulu maʻamau he kiʻekiʻe kiʻekiʻe ka nui o ka sima, a ʻo nā papa i hoʻokaʻawale ʻia e nā lako mea maʻamau he mau pū a i ʻole nā ​​kui kila, no laila ke kuʻi ka pahi me nā mea paʻakikī i ka wā e ʻokiʻoki ai. ʻO ka lāʻau e koho maʻamau i nā ʻāpana me ka paʻakikī haʻahaʻa a me ka ʻoi aku ka paʻakikī. ʻO ia mau mea hoʻohui e koho maʻamau i ka tungsten carbide me ka nui o ka palaoa a me ka nui, a ʻoi aku ka kiʻekiʻe o ka ʻike o ka binder phase. ʻO ka paʻakikī ʻo Rockwell o ia mau ʻāpana maʻamau ma lalo o 90. ʻO ke koho ʻana i ka carbide cemented no nā mea hana ʻoki lāʻau ʻaʻole wale ia e pili ana i nā ʻano o ka ʻoki lāʻau, akā ʻo ka hale hana mea hana maʻamau ke alakaʻi i nā kānana piha e like me kāna kaʻina hana ponoʻī, nā lako hale hana lako. a me ka ʻenehana hana a me nā kūlana ʻē aʻe e pili ana, a koho hope i ka carbide cemented me ka hoʻohālikelike maikaʻi loa.
