Kōwhiringa Rauemi Matua

He hononga tata te kōwhiringa o ngā rauemi matua ki te mahi. Ko te diameter matua o ngā muka aratau-kotahi he 8–10 maikorona. He tino pai mō ngā tuku tere-teitei nā te mea kotahi noa te ngaru mārama ka taea te tuku, ka whakaiti i te kaha o te pokanoa.

Mā ngā rauemi silica parakore ka mārama rawa te tuku raraunga i tawhiti rawa atu. Ina koa, he pai ake ngā matua polymer i ngā tono tawhiti poto, ka whakamahia tōna ngāwari ki te tu atu i ngā momo taumahatanga, tae atu ki te tāutanga me ngā pānga taiao.

Ko te whiriwhiri i te rauemi tika ka ahu mai i ngā hiahia motuhake o ia whatunga, tae atu ki te tere, te tawhiti, me ngā āhuatanga whakahaere e whakaarohia ana.

Ngā Tikanga Whakahaere Tika

Nō reira, he mea nui te āta whakahaere i te whakatinanatanga me te tiaki tonu. Kaua e pikohia ngā taura kia nui atu i tō rātou radius iti rawa, ā, whakamahia ngā kuru muka tohatoha Bragg hei ine i te taumahatanga.

Whāia ēnei aratohu:

Me mahi: Whakamahia ngā karapu tiaki, rongoatia ngā taura kia tika, ā, tirohia te tūnga tika.

Kaua e: Toia ngā taura mā te kaha, whakawhāiti rawa i ngā here, waiho rānei ki te wera.

Whakamutunga

Ko te matua taura muka whatu te tūāpapa mō te tuku raraunga tere, pono hoki. Ahakoa he matotoru, he rauemi, he hangarau rānei, ka pāngia te tere, te mārama, me te whai huatanga e ngā āhuatanga katoa o te matua. Mā te whiriwhiri i te momo matua tika, te piri ki ngā tikanga tāutanga tika, me te whai mōhio ki ngā hangarau hou ka āwhina i a koe ki te whakatutuki i ngā hua tino pai. Nā te haere tonu mai o te mana whakahaere kounga me ngā auahatanga, e pana ana i ngā muka whatu ki mua, ki mua, kua noho te taura muka whatu hei wāhanga nui o te whakawhitiwhiti kōrero o ēnei rā.

Ahakoa kei te whakamahere koe i tētahi hononga whakamutunga, i tētahi whakatinanatanga ā-motu rānei, mā te mōhio ki ngā mea kei raro i te whakatairanga hokohoko ka ārahi koe ki te whakatau whakaaro nui ake. He pūtaiao te muka whatu mō te tika me te mahi, ā, ko te matua te matua o te pūtaiao. Hei whakarite i ngā hononga tere me te pono me te rere o ngā raraunga, he pai te haumi ki te matua tika.

Ngā Pātai Auau

He aha te uho o te taura muka whatu?

Ko te uho te aho angiangi o te taura muka whatu, he mea hanga ki te karāhe, ki te kirihou rānei. Koinei te wāhanga o te taura muka whatu e kawe ana i ngā tohu mārama hei tuku raraunga. He mea nui te kounga me te rahi o te uho hei whakahohe i te whakawhiti raraunga nui.

He pēhea te pānga o te matua ki te tuku raraunga?

Ko te uho te reo e whakawhitihia ai ngā tohu mārama ki te whakawhiti raraunga. Ko te mārama ake, ko te pumau ake o te uho, ko te tere ake, ko te pono ake hoki o te tuku raraunga mā roto i ngā muka me te iti o te ngaronga raraunga, te whakararuraru rānei.

He aha te rerekētanga i waenga i ngā matua aratau-kotahi me ngā matua aratau-maha?

Ka puta he hihi putanga kotahi i ngā matua aratau-kotahi, he whaiti ake (tata ki te 8-10 maikorona te whānui) ā, he pai ake mō ngā tawhiti roa. Ka puta he matua nui ake (50-62.5 maikorona) ka whakamahia mō ngā tawhiti poto ake me ngā whānui whānui teitei ake.

He aha ngā āhuatanga e pā ana ki te mahi matua muka whatu?

Ka pāngia te mahi matua e te kounga o ngā rauemi, te ma, te tika o te diameter o te matua, me te whakaurunga ki te ngongo taura. Ahakoa ngā āhuatanga o waho, pērā i te piko, te totoro rānei o te taura i te wā e whakamahia ana, ka pāngia te mahi.

Me pēhea te whakahaere i te kounga matua i te wā e hangaia ana?

Ka whakawhirinaki ngā kaihanga ki ngā pourewa kume muka hou hei whakapūmau i te tika o te diameter matua, te parakore o ngā rauemi, me te pono o ngā hapa karaihe. Mā te whakamātautau pakari ka pumau te mahi me te piri ki ngā paerewa ANSI/TIA.

Ka taea e te tāutanga hē te kino i te matua muka whatu?

Āe. Mēnā ka nui rawa te piko, te pēhanga rānei e pā ana ki te matua o te taura muka whatu i te wā tāutanga, ka pakaru, ka whakapē rānei te matua, ka ngaro, ka motuhia rānei te tohu. Ko te piri ki ngā tikanga pai te mea nui.

He aha ngā auahatanga hou o te hangarau matua muka whatu?

Kei roto i ngā whanaketanga hou ko ngā matua kore-piko, ngā kaha whānui pai ake, me ngā rauemi e mau tonu ana ki te taiao. E arotahi ana ēnei auahatanga ki te whakapiki i te roa, te whai huatanga, me te pumau. He tino pai mō ngā whatunga raraunga o ēnei rā e whānui haere tonu ana.
