Mai i ngā Rauemi Mata ki te Whakamahinga: Muka Pātarati
muka pātaratihe mārama ngā painga o ngā hua ki te muka karāhe Ngā Rauemi WhakakotahiI roto i ngā āhua o te whāriki tapatapahi, te kakahu hurihuri, me te papanga kotahi-angi,muka pātarati e whakaatu ana i ngā kawenga pakaru teitei ake me te modulus a Young (he ine i te pakari mō tētahi rauemi) ki te whakataurite ki te muka karāhe.
I roto i tētahi rangahau i whakahaerehia e Ahorangi Ignaas Verpoest o te Tari Rauemi Hikoi i Te Whare Wānanga o Luvin i Belgium, i whakahaerehia he rangahau mō Pātarati muka me te muka karāhe-E. I whakaritea ngā prepreg kotahi-angi mā te whakakī i te karāhe me te papara ki te kapia epoxy, ka takai ki runga i te mandrel, kātahi ka pēhi i ngā papa rākau kia mārō rawa. I tapahia ngā tauira he 135 mm × 15 mm (5.3 inihi × 0.6 inihi) te rahi, ā, i inehia te matotoru. Kātahi ka whakamātauhia ngā tauira ki te piko-toru-ira (ISO 178) me ngā whakamātautau ILSS (ISO 14130) hei aromatawai i te kaha me te pakari.
E ai ki a Verpoest, ahakoa he 40% te rahinga muka o ia tauira, he 13.7% teitei ake te kaha o ngā tauira basalt/epoxy i tērā o ngā tauira karāhe-E, ā, he 17.5% teitei ake tō rātou pakari, ahakoa he 3.6% te taumaha o ngā tauira basalt i ngā tauira karāhe-E.
Hei tāpiri atu, he ātete ā-tūturu te muka o te papare ki te hihi ultraviolet (UV) me te hihi hikohiko kaha-teitei, e mau tonu ana ōna āhuatanga i ngā pāmahana iti, ā, he pai ake te ātete ki te waikawa. E ai ki ngā pūrongo he pai ake ngā painga o te papare mō te haumaru o ngā kaimahi me te kounga o te hau. Nā te mea he hua te papare i puta mai i ngā mahi puia, he pai ake te tukanga whakapūtanga muka ki te taiao i te muka karāhe. Hei tāpiri atu, he 100% te koretake o te papare, arā, kāore he tauhohenga paitini ki te hau, ki te wai rānei, ā, kāore e mura, ā, he ātete ki te pahūtanga.
Ngā tono i roto i te Tiaki Ahi me te Ārai Wera
muka paratati whatu He tino pai te ātete ki te pāmahana, he pai te whakamarumaru wera, kāore e rewa, kāore hoki e maturuturu, kāore he tukunga hau paitini, ā, kāore hoki e heke te pāmahana. He rauemi pai rawa atu mō ngā kākahu ahi, ngā paraikete ahi, me ngā ārai ahi, me te ātete pāmahana tae atu ki te 650∘C me te taupū hāora here nui atu i te 68, he pai ake i te aramid me ētahi atu muka rauropi.
Ngā Taupānga i roto i te Hanganga
muka pātarati He kaha te kume, he ātete ki te waikawa me te kawakore, ā, he pumau hoki ōna āhuatanga matū. Ka taea e ia te whakakapi i ētahi wāhanga o ngā pepa muka waro mō te whakatikatika, te whakahou, me te whakapakari i ngā hanganga. Ka taea hoki e ia te whakakapi i te muka polyester, te muka polypropylene, me te muka polyacrylonitrile mō te whakapakari i te raima moata me te raima uku, e tuku ana i te ātete kaha me te ātete pakaru. Ka taea te whakamahi whānui i roto i ngā mara hanganga pēnei i ngā huarahi tere, ngā ara rererangi, ngā tauranga moana me ngā tauranga, me ngā hanganga hangarau hiko wai.
Ngā tono i roto i te Tiaki Taiao
He momo rauemi matomato hou, he rauemi hoa taiao hoki te muka basalt, ka taea te whakamahi hei tiaki taiao mō te tātari, te mimiti, me te purenga o ngā mea kino me ngā hau. Ina koa i roto i te tātari pāmahana teitei, ko te pāmahana whakamahinga roa o muka pātarati he 650∘C, he pai rawa atu i ngā rauemi tātari tuku iho, ā, koinei te rauemi pai mō ngā papa tātari, ngā rauemi tātari, me ngā whariki pāmahana-tiketike.
Ngā Whakamahinga o ngā Kirihou Whakakaha Muka Pātarati
Ngā rauemi whakakotahi i whakapakaritia ki muka pātarati ka taea te whakamahi i roto i ngā mahi tiaki whenua pēnei i te pukupuku ātete matā, ngā radom, te tiaki wera o te pū, me ngā rauemi huna mō te mimiti me te tuku radar. Ka taea hoki te whakamahi i roto i ngā mahi ā-iwi pēnei i ngā hanganga waka me te kaipuke, ngā paipa ātete-pēhanga me te ātete-waikura, ngā rango pakaru, me ngā papa hiko tā.
