He aha te whitiki hangai?

He taputapu hiki ngāwari te taura hangai, he mea hanga mai i ngā muka hangai, he mea hanga motuhake mō te hiki me te neke i ngā kawenga me te haumaru me te whai hua. He mea nui tana mahi i roto i ngā ahumahi pēnei i te hanga, te hanga, te whakahaere waka, ngā tauranga, te rererangi, me ngā matū hinu. Ki te whakatauritea ki ngā taura waea tuku iho, he maha ngā painga o ngā taura hangai tae atu ki te taumaha iti, te ngāwari, te rauemi kore kino, me te haumaru teitei—he mea nui ēnei i roto i ngā mahi hiki hou.

Te Whakamāramatanga o te Whitiki Hanga

He mea hanga te whitiki hangai mai i ngā muka hangai kaha-teitei pērā i te polyester (PES), te polyamide (PA, e mōhiotia whānuitia ana ko te nylon), te polypropylene rānei (PP). E rua ngā āhua matua: ko ngā whitiki whatu papatahi me ngā whitiki porowhita.

Ngā Momo Taupoki Hangahanga

• Whitiki Whatunga PapatahiHe mea hanga mai i ngā paparanga maha o ngā muka polyester kaha-teitei, he whānui, he papatahi hoki tōna mata, he pai mō te hiki i ngā mea papatahi me ngā mea āhua rite. Ko ngā kanohi he mea whakapakari kia pai ake ai te ātete ki te kakahu me te haumaru.

• Te taura porowhitaHe mea hanga mai i ngā koropiko tonu o ngā miro muka kaha-teitei kua takaihia ki roto i tētahi ringaringa tiaki. He tino ngāwari, he tohatoha kawenga, ā, he iti ake te tūponotanga o te takahuri. He pai mō te hiki i ngā taonga koretake, ngā mea ngawari rānei, he pai ake te tiaki i ngā whitiki papatahi.

Ngā Whakamahinga Noa o ngā Taura Hanga

• Te Hiki MīhiniHei hiki i ngā mīhini, ngā taputapu, ngā wāhanga maitai rānei i ngā wāhi hanga, huihuinga, me te tāutanga.

• Ngā Tauranga me ngā Ratonga WhakahaereE whakamahia whānuitia ana mō te whakahaere ipu me te neke rauemi papatipu nā te mea he ngāwari, he kore hoki e kino.

• Hanganga: E whakamahia ana hei hapai i ngā rebar, i ngā mahi hanga, i ngā panera kua oti te whakarewa, me ētahi atu, i ngā papa hangahanga, he maha ngā wā ka whakamahia ngātahitia me ngā kerēne.

• Te Mana Hau me te Ahumahi TaumahaHei hiki i ngā wāhanga hanganga nunui pērā i ngā mata o te tāhū hau, i ngā pourewa rānei, he maha ngā wā ka whakamahia ngā whitiki porowhita hei tiaki me te kaha.

• Te Whakahaere i ngā Taputapu Rererangi me te TikaHe mea tino pai mō te hiki i ngā taputapu utu nui, tairongo rānei, nā te mea ka ārai ngā whitiki i ngā karawarawa me te whakarerekētanga o te āhua.

Ngā Painga o ngā Whitiki Hangahanga

• Ngāwari, ā, kāore e kinoKi te whakaritea ki ngā taura waea rino, kāore ngā taura hangai e rakuraku, e pēhi rānei i ngā mata kawenga, ā, he pai mō ngā mea pania, ngā mea tika rānei.

• Mama, ngāwari hoki te whakahaereHe mama ake i ngā taura maitai he rite te kaha, he ngāwari te kawe, te whakatū, me te penapena i ngā taura hangai—he tino whakapai ake i te whai huatanga.

• Teitei o te Kaha me te Haumarutanga:

  Ko te hoahoa o ngā whitiki hangai he 5:1, 7:1, 8:1 rānei hei whakarite i te whakamahinga haumaru.

• Ātete ki te waikura me te pirauHe tino ātete ngā rauemi ki te wai, te hinu, me ngā matū, ā, ka taea te whakamahi i roto i ngā taiao uaua.

• Ka taea te whakariteE wātea ana i roto i ngā roa, ngā whānui, ngā paparanga, me ngā hononga pito hei whakatutuki i ngā hiahia hapai rerekē.

Me pēhea te whiriwhiri i te whitiki hangai tika

I te wā e whiriwhiri ana i tētahi whitiki hangai, whakaarohia ngā āhuatanga e whai ake nei:

• Taumaha me te Momo UtainaKōwhiria te momo e tika ana (papatahi, porowhita rānei), te kaha kua whakatauria, me te roa i runga i te āhua, te taumaha, me te mata o te kawenga.

• Tikanga HikiHe rerekē te whānui me ngā hanganga o te whitiki e hiahiatia ana mō ngā momo whirihoranga hiki—hikinga tika, hiki-U, waewae-rua rānei.

• Auautanga me te TaiaoMō te whakamahinga auau, mō ngā taiao kino rānei (hei tauira, te pāmahana teitei, te waikawa/kawakore, te haumākū), whiriwhiria ngā whitiki he paninga tiaki, he rauemi motuhake rānei.

• Ngā Paerewa me ngā TiwhiketeKōwhiria ngā hua e tutuki ana i ngā paerewa e tika ana pēnei i te EN 1492-1/2, ASME B30.9, rāneiAS4497.1hei whakarite i te kounga me te haumaru.
