Hononga Poraka Whakamutunga Whāngai Momo H Hononga Rīpene Pitch

Ko ngā poraka pito momo-H he momo pito waea e whakamahia whānuitia ana, i tapaina mō tō rātou turanga ārai he rite te āhua ki te reta 'H' (e kiia ana ko te momo-U, ko te momo-roto rānei). I te nuinga o te wā ka whakamahia e rātou te hangarau waea hono-tīwiri hei whakatutuki i ngā hononga hiko haumaru, pono hoki.

Ko te whakamahinga matua o ngā poraka pito momo-H he mea hei pūwāhi mō te whakapūmau, te hono, me te hono i ngā waea hiko me ngā taura. Ka haria mai e rātou ngā waea mai i te pūtake hiko, i te pito o mua rānei o tētahi taputapu, ā, mā roto i ngā wāhanga whakarewa kawe hiko o roto, ka tukuna te iahiko, ngā tohu rānei ki te pito o muri, ki tētahi atu waea rānei, hei pūwāhi whakawhiti, tohatoha, whakawhiti rānei. Nā te ngāwari o te hanganga, te iti o te utu, me te ngāwari o te whakamahi, he whānuitia te whakamahinga i roto i ngā āhuatanga maha: Ahumahi rama: He whānuitia te whakamahinga i roto i ngā waea o roto o ngā rama LED, ngā rama hihiko, me ngā rama tuanui, hei wāhanga paerewa mō ngā hononga rama. Hanga taputapu kāinga: Ka whakamahia i roto i ngā taputapu ahumahi me ngā taputapu whare pēnei i ngā pā, ngā mīhini horoi, me ngā ngaruiti, hei whakapūmau me te hono i ngā ara iahiko o roto. Taputapu hiko me te hikohiko: He mea noa i roto i ngā taputapu tuku hiko, ngā tātari, ngā kāpata whakahaere hiko, me ngā taputapu tuku, he mea tino pai mō ngā āhuatanga e hiahia ana ki te otinga 'pakipaki-roto', me hono ngā waea mai i roto i te kāpata ki waho. Ngā whare arumoni me ngā whare tūmatanui: Whakamahia mō te rama whata hūpāmakete, ngā papa pānui, ngā pūnaha hiko rangitahi, me ētahi atu wāhi e hiahia ana ki te waea tere, ki te tohatoha rānei.

Ko ngā rauemi o ngā poraka pito momo-H e wehea ana ki ngā wāhanga kirihou ārai me ngā wāhanga konganuku kawe hiko. Ka pā tika te rauemi o te whare ki te ātete pāmahana o te hua, te ātete mura, me te mahi ārai. Ko ngā rauemi noa ko: Nylon 66 (PA66): Ko te mea e whakamahia whānuitia ana. He pai rawa te ātete mura (ko te whakatauranga ātete ahi ko te UL94 V-2, V-0 rānei), te ātete pānga, me te ātete whakarewa. Ko te awhe pāmahana mahi ko te -30℃ ki te 110℃, me te manawanui poto tae atu ki te 140℃. Polyethylene (PE): He pai te ngāwari, te mārama, me te roa, ā, he ātete ki te irahiko. Heoi, he iti ake te ātete pāmahana, ko te -40℃ ki te 65℃. Polypropylene (PP): He pai te ātete mura me te ātete pānga kaha, engari he iti te mārama me te paku pakari. Ko te pāmahana mahi kei te -20℃ ki te 90℃. Polycarbonate (PC): Ko ētahi pito kounga teitei e whakamahi ana i te rauemi PC, e tuku ana i te ātete mura teitei ake (UL94 V-0) me te mahi whānui tino pai. Ngā wāhanga/pānga arataki: He mea hanga i te parahi (he maha ngā wā ka whakamahanahia hei whakanui ake i te kaha taipana me te ārai i te pakaru), ngā koranu parahi, te parahi hiko rānei hei whakarite i te arataki pai rawa atu. Ngā anga tīwiri/rawhi: He mea hanga ki te rino, ki te koranu parahi rānei, he maha ngā wā ka rongoatia ngā mata pēnei i te whakakikorua konutea (tae, mā rānei), te whakakikorua nikara, te whakakikorua tine rānei hei whakarei ake i te ātete waikura me te ārai i te waikura hikohiko me ngā waea parahi i roto i ngā taiao makuku.
