Ngā Tohu Koranu Niho Kani mō te Mīhini i ngā Rauemi Rākau me te Konumohe

Whakaahuatanga Poto:

"Ko ngā āhua niho o ngā pane mata kani he pito waro te nuinga ko ngā niho maui-matau, ngā niho papatahi, me ngā niho papatahi takahanga. I tēnei wā, mō te tapahi i ngā mata kani e whakamahia ana i roto i ngā rauemi rakau me te konumohe, ko ngā niho maui-matau te mea tino noa. I muri i te whakarewa i ngā niho, me huri te niho maui-matau."

Ko ngā rahi o ngā mata kani karāhe e whakamahia ana mō te tapahi rakau. Ko ngā diameter o ngā mata kani iti noa ko te 4 inihi, 7 inihi, me te 9 inihi. I te tapahi i ngā papa matotoru, ko ngā mata kani he diameter 900mm me te 1200mm te mea e whiriwhiria ana. Mō ngā mata kani tapahi konumohe, he nui ake ngā diameter, mai i te 800mm, 1200mm, 1400mm, ki te 1800mm. Ka piki ake ngā rahi o ngā pito karāhe kua tīpakohia me te diameter o te mata. I tēnei wā, ko tā mātou kamupene te nuinga e hanga ana i ngā mata kani karāhe mō te tapahi konumohe, me ngā whakatakotoranga pokepokea tae atu ki te 9030, 10535, 12040, 14550, 17050, 19050, me ētahi atu. Ka taea te whakarite i te whānui o te wāhanga waenga kia rite ki ngā whakaritenga.

Mō ngā mata kani tapahi rakau, kei a mātou ngā whakaritenga pēnei i te 7021, 8030, 7525, me ētahi atu. Ka taea e Kimberly te whakawhanake me te whakaputa kia rite ki ngā hiahia me ngā rauemi a te kiritaki.

Tono

Ko ngā mata kani koranu mārō e whakamahia ana mō te tapahi i ngā momo rauemi, tae atu ki ngā mata kani rakau, ngā mata kani konumohe, ngā mata kani tāera asbestos, me ngā mata kani maitai. He rerekē ngā momo rauemi mata koranu e hiahiatia ana mō ngā momo mata kani koranu rerekē nā te mea he rerekē ngā whakaritenga mō te pakeke me te ātete ki te kakahu o ia rauemi.

Ngā mata kani rakau:
Hei tapahi rakau, he mea hanga i te koranu mārō waenga-kiko YG6, YG8 rānei. He pai te mārō me te mahi tapahi o tēnei rauemi koranu, he pai mō te tapahi rakau.

Ngā mata kani konumohe:
Hei tapahi i ngā rauemi konumohe, he mea hanga i te nuinga o te wā mai i te koranu mārō kikokore YG6, YG8 rānei. He ngohengohe te konumohe, nō reira me nui ake te mārō o te mata koranu kia pai ai te tapahi me te roa o te wā.

Ngā mata kani tāera asbestos:
Tērā pea ka hiahiatia he hoahoa motuhake mō ēnei momo mata hei whakahaere i ngā rauemi mārō, pakarukaru hoki pērā i ngā tāera asbestos. Tērā pea ka rerekē te rauemi koranu motuhake i runga i te kaihanga me ngā whakaritenga.

Ngā mata kani rino:
Whakamahia mō te tapahi i ngā rauemi maitai, he mea hanga i te koranu tungsten titanium. He tino pakeke ngā rauemi maitai, ā, he ātete ki te pakaru, nō reira me whakamahi he rauemi mata pakari ake hei whakatau i tēnei wero.

Hei whakarāpopototanga, me whai rauemi mata mata koranu tika ngā momo mata kani rerekē hei whakatutuki i ngā whakaritenga o ngā rauemi rerekē, hei whakarite hoki i te pai o te tapahi me te roa o te wā e mau ai te taputapu. Mā te whiriwhiri i te rauemi koranu pakeke tika ka taea te whakapai ake i te mahi me te roa o ngā mata kani.

Ngā Āhuatanga

Ko ngā koranu mata kani he mea hanga i ngā koranu mārō (e mōhiotia ana ko ngā koranu tungsten carbide, ko ngā koranu tungsten-cobalt rānei) ā, he maha ngā āhuatanga matua e pai ai mō ngā taputapu tapahi. Anei ētahi o ngā āhuatanga matua o ngā koranu mata kani:

Teitei o te Pakari:
He tino mārō ngā koranu mārō, ā, ka taea te ātete ki te pakaru me te hurihanga i te wā e tapahi ana. Mā tēnei ka taea e ngā mata kani te pupuri i te mata koi me te pumau o te mahi i te wā e tapahi ana.

Ātete Pakaka Pai rawa atu:
He tino ātete te koranu mārō ki te kakahu, ā, ka mau tonu ki ngā mahi tapahi auau me te kore e rahua. Ka roa ake te ora o te mata.

Kaha Teitei:
He kaha rawa ngā koranu o te mata kani, ā, ka taea te tu atu i te pānga me te pēhanga i te wā e tapahi ana, ka whakaiti i te mōrearea o te whati, te whakarerekē rānei i te āhua.

Te Pūmautanga Pai o te Wera:
Ka taea e ngā koranu mārō te pupuri i tō rātou pakeke me te pumau ahakoa i raro i ngā āhuatanga pāmahana teitei, he mea nui tēnei mō ngā mahi tapahi tere-tiketike.

Te Mahi Tapahi Pai:
He tino pai te mahi tapahi a ngā koranu mārō, e whakarite ana i te whai huatanga o ngā mahi tapahi me te whakaiti i te whakapaunga pūngao i te wā tapahi.

Te Pūmautanga Matū:
He nui te ātete o ngā koranu mārō ki ngā momo matū, ā, ka roa ake te ora o te mata kani.

Te āheinga ki te whakarite:
Ka taea te whakarite i ngā koranu mārō kia rite ki ngā whakaritenga tapahi motuhake, kia taea ai te whakarerekē i te hanganga o te koranu kia tutuki ai ngā hiahia o ngā rauemi rerekē.

Hei whakarāpopototanga, ko ngā āhuatanga o ngā mata kani koranu mārō he mea tino pai mō te tapahi i ngā momo rauemi, he ātete ki te kakahu, he pakeke, he kaha, he pai hoki te pumau ki te wera, he mea e tika ana mō ngā momo mahi tapahi rerekē.
