Whakautu tere: Ko te matotoru o ngā rūma raka maitai me tohu i roto i ngā mirimita, kaua i roto i te ine — he rerekē ngā pūnaha ine i runga i te whenua me te rauemi, engari he mārama te mm. Ko ngā rūma raka kounga teitei he mea hanga mai i te maitai hurihuri-makariri 0.4–1.0 mm: 0.4–0.5 mm mō te whakamahinga tari māmā, 0.6 mm hei paerewa mō ngā kura me ngā tari, 0.8 mm mō ngā wāhi e nui ana te haere o te tangata, me te 1.0 mm mō te whakamahinga taumaha. Manatokohia tētahi utu me te tauira inehia ki te caliper, te tiwhikete mira maitai rānei.
I tukuna mai e tētahi kaihoko i Nigeria tētahi utu mai i tētahi kaiwhakarato e tuku ana i ngā rūma raka "22 gauge" i tētahi utu tino pai. I pātai mai ia he aha te tikanga o te 22 gauge i roto i ngā mirimita kia taea ai e ia te whakarite ki tā mātou tuku 0.6 mm. I mahia e au te hurihanga, ā, ko tana rūma raka "iti" 22-gauge he angiangi ake i tā mātou i tētahi i tētahi utu nui ake. Kāore ia i pātai anō mō te gauge.
Ko te matotoru te mea e arohia ana e ngā kaihoko - ā, ko te nuinga o te wā ka whakahēngia e ngā kaiwhakarato. Anei me pēhea te whakaaroaro mārama mō te matotoru o ngā raka rino.
He aha te "Ine" he Mahanga mō ngā Kaihoko o te Ao
He pūnaha tau tawhito te ine, ā, ko te tau teitei ake he angiangi ake te maitai — ā, he rerekē te mahere i waenga i ngā paerewa. Ko te ine pepa maitai o Amerika, te ine waea paerewa o Peretānia, me te ine kowiri tira e tuku ana i ngā uara mirimita rerekē ki te tau kotahi. Ko te kaiwhakarato e whakahua ana i te "18 gauge" me te kore e whakahua i te paerewa kei te whakahua i tētahi tau e tohu ana i ētahi matotoru rerekē.
Ngā huringa matawhāiti i raro i te paerewa pepa maitai noa o Amerika, hei whakahāngaitanga anake:
| Ine (pepa maitai US, tata) | matotoru |
|---|---|
| 26 mehua | ≈ 0.45 mm |
| 24 mehua | ≈ 0.6 mm |
| 22 mehua | ≈ 0.75 mm |
| 20 mehua | ≈ 0.9 mm |
| 18 mehua | ≈ 1.2 mm |
Mātakitaki i te mahanga: ka whakahua noa ētahi mākete i te kupu "gauge" mā te whakamahi i tētahi ripanga rerekē, ā, ka whakamahia noa e ētahi kaiwhakarato te kupu hei whakaputa hangarau i a rātou e tuku ana i te mea he aha te āhua o te koiri. Ka tangohia katoatia e ngā mirimita te koretake. Koia te take e kīia ai te matotoru o ngā tono a-ao, me ā mātou ake pepa whakahua, i roto i te mm — ā, he aha mātou ka akiaki i a koe ki te pātai ki tētahi kaiwhakarato, ahakoa te tau e whakahuatia ana e rātou, "ā, he aha te nui o tēnā i roto i te mirimita, i runga i te tiwhikete mira?"
Te Matotoru o te Rūma Rākau Rino mā te Whakamahinga
Kāore he "matotoru paerewa" whānui — he whānuitanga mahi kei reira, ā, ko te pūwāhi tika kei runga i te kaha o te rūma raka. Koinei te whitiki e hangaia ana e mātou, me pēhea hoki te tohatoha:
| matotoru | Te whakamahi angamaheni | He aha te tumanako |
|---|---|---|
| 0.4-0.5 mm | He māmā te whakamahinga o ngā tari, he rūma kaimahi, he iti te haere o ngā taonga | He pai mō ngā taiao ngawari; ka pakaru mēnā ka whakamahia kinotia |
| 0.6 mm | Ngā kura, ngā tari, ngā whare takaro tinana — ngā mea tino pai | Ka ora i ngā patupatu o ia rā, o ia rā, me ngā patupatu noa mō ngā tau maha |
| 0.8 mm | Ngā ara e nui ana te haere o ngā tāngata, ngā rūma whakarerekē kakahu ā-ahumahi | He pakari te āhua o te tatau; ātete ki te pakaru |
| 1.0 mm | Mahi taumaha: ngā wheketere, ngā hōia, ngā wāhi keri maina | Te ātete nui ki ngā pakaru; te mea taumaha rawa atu, me te mea utu nui rawa atu |
Ko te pono o te hangarau: ko te pikinga mai i te 0.4 ki te 0.6 mm te mea nui ake i te pikinga mai i te 0.8 ki te 1.0 mm. I raro iho i te 0.5 mm, ka ahua ngoikore, ka piko hoki ngā tatau i te tūru o te peke tuara. I te 0.6 mm me ngā kōtaha takai tika (he nui ake ngā kōrero mō tēnā i raro nei), ka taea e te rūma raka te pupuri i te ara raro o te kura mō te tekau tau. I runga ake i te 0.8 mm, ka utua e koe te moni tāpui mō te tukino, ehara i te mea mō tētahi atu momo hua.
Me pēhea te manatoko i te matotoru i whakahuatia ki a koe
He pai te whakawhirinaki; he pai ake te caliper. E toru ngā taumata manatoko, e piki haere ana te raupapa o te pakari:
- Tauira + caliper. Tonoa he tauira i mua i te hanga, ka ine i te panera i ngā pūwāhi e toru, e whā rānei te tawhiti atu i ngā taha kua tapahia (ka taea te pānui he paku matotoru ngā taha mai i ngā pūwero). Ka pānui te caliper matihiko $15 ki te 0.01 mm.
- Tiwhikete whakamātautau mira. Ka tukuna e te mira maitai he tiwhikete mō ia puranga koiri e whakaatu ana i te matotoru tuturu. Ka taea e tētahi wheketere nui te whakaputa, nā te mea ka hokona e rātou he koiri kia rite ki ngā whakaritenga — tirohia me pēhea te huri o te koiri hei panera i roto i tā mātou aratohu mō te hanga o ngā rūma raka rino.
- Arotakenga a te hunga tuatoru. Mō ngā ota rahi ipu, tāpirihia te ine matotoru ki te rārangi arowhai tirotiro i mua i te tuku. He inihua iti te utu.
Kotahi te whakatūpato mō te āhua o te tuku kōrero a ngā kaiwhakarato: pātai atu mēnā kei mua , kei muri rānei i te paninga paura te tau. Ka taea e te panera pania te pānui i te matotoru o te 0.1–0.2 mm i runga i te caliper i te maitai tahanga i raro iho. Ko te mea nui ko te matotoru o te maitai tahanga, ā, e kī ana te tiwhikete mira i tēnā.
Ehara te matotoru i te mea katoa: Ko te haurua o te mahi a te kopa
Anei te wāhanga e ngaro ana i te nuinga o ngā aratohu hoko. Kāore te panera papatahi 0.8 mm e pakari ake i te panera 0.6 mm kua hoahoatia pai, nā te mea ko te pakari o te panera e ahu mai ana i te āhuahanga me te matotoru. I te pēhi pēhi, ka whakapikohia ngā taha o ia panera ki ngā kōhao 90° — ā, ka whakanuia e te taha whakapiko te ātete o te panera ki te piko, koia anō te take kāore he mea e mau ana i te pepa engari ko te pepa kotahi kua whakapikohia ki roto i te awaawa hei pupuri moni.
Nō reira, ina whakaritea e koe ngā rūma raka e rua i te taurite mm kotahi, tirohia te taha o te tatau: ka māro te āhua o te tatau he piko katoa te taha me te whakakaha o roto; ka piko te tatau he pepa papatahi he remu noa iho. Ka mahi tahi te matotoru, te hoahoa piko, me te hanganga hononga - he whakapakari whakarewa, he pereti nati KD rānei. Ko te arorau kotahi tēnei e wetewetehia ana e mātou i roto i tā mātou whakataurite KD vs whakarewa : ko te hanganga te whakatau i te kaha o te ao tūturu, ehara i te tau kotahi.
Ngā Tohu Whero a te Kaiwhakarato mō te Matotoru
- Ngā kōrero mō te ine-anake e kore e tahuri ki te mm ina tuhia.
- "Te matotoru toharite" reo — he awhi manawanui tō te koiri; me whakaatu te kōrero mō te matotoru ingoa me te manawanui, kaua e whakaatu i te toharite koretake.
- He iti rawa te utu i te mākete i te "matotoru" o te whakaritenga — ko te maitai te utu nui rawa atu mō te kotahi rūma kakahu. Ko te utu iti rawa o te 0.8 mm he koiri 0.6 mm te nuinga o te wā.
- Kāore he kaupapa here tauira. He wheketere e whakapono ana ki ana tauira kaipuke. Ā mātou rārangi arowhai manatoko kaihanga e tirotiro ana i te hiahia o te tauira hei tohu matua.
Ā, kia ōrite te whakatakotoranga ki te wāhi mahi, kaua ki te whakapehapeha. Ko te rūma raka 1.0 mm i roto i te tari kaute marino he moni e pau ana ki te ātete ki te tukinotanga e kore rawa e whakamahia - he maha ngā wā ka hokona e te tahua kotahi te uara pai ake i te maitai 0.6 mm me ngā raka, ngā inihi, me te paninga pai ake. Ka ārahihia e tā mātou aratohu rūma raka kura te taurite mō ngā kaupapa o te kāmpus.
Pātai Auau
He aha te matotoru paerewa o te rūma raka maitai?
Kāore he paerewa kotahi — ko te whakautu pono he whānuitanga e rite ana ki te whakamahinga. Ko te nuinga o ngā wheketere kounga teitei ka hanga i ngā rūma raka maitai mai i te 0.4 ki te 1.0 mm te maitai hurihuri-makariri: 0.4–0.5 mm mō te whakamahinga tari māmā, 0.6 mm hei whakaritenga mahi mō ngā kura me ngā tari, 0.8 mm mō ngā wāhi e nui ana te haere o te tangata, me te 1.0 mm mō te whakamahinga ahumahi taumaha.
He pai ake te ine, te mm rānei hei tohu i te matotoru o te maitai?
Ngā Mirimita. He rerekē ngā pūnaha ine i ia whenua me ia rauemi — ka rite te tau ine ki ngā matotoru rerekē i roto i ngā paerewa rino, waea, me te kowiri tira o Amerika. He mārama ngā mirimita, koia te take e whakahua ai ngā utu a ngā kamupene tuku tono o te ao me ngā wheketere nui i roto i te mm.
Me pēhea taku tirotiro i te matotoru o te rino o tētahi rūma raka i whakahuatia mai ki ahau?
Tonoa he tauira i mua i te hanga, ā, inehia te panera ki te caliper mamati i ētahi wāhi e matara atu ana i ngā taha kua tapahia, me tono rānei i te tiwhikete whakamātautau mira mō te koiri maitai. Mō ngā ota nui, tāpirihia he tirotiro tuatoru e whakauru ana i te ine matotoru ki te rārangi arowhai.
He tikanga tonu rānei te matotoru o te maitai kia kaha ake te rūma raka?
Kāore i te katoa. Ka puta anō hoki te pakari o te panera i ngā kōtaha taha kua pikohia i hangaia i te pēhi pēhi — ka taea e te panera 0.6 mm me ngā kōhao 90-tohu tika te mahi pai ake i te panera papatahi 0.8 mm. Ka mahi tahi te matotoru, te hoahoa piko, me te hanganga hononga.
He aha te matotoru o te maitai e hiahiatia ana mō ngā rūma raka kura?
Mō ngā ara raro o te kura e pakia ana ngā tatau e rau ngā wā i te rā, ko te matotoru o te tinana me ngā panera tatau he 0.6 mm te iti rawa, ā, ko te matotoru o te 0.8 mm mō ngā tatau i ngā taiao tino uaua. Ki te iti iho i te 0.5 mm, me kite koe i ngā pakaru i roto i ētahi wāhanga kura.
