Pareaku. He aha te mea tenei mea, a he aha te mea i tona whakamahi

I aua ra, ka kua kaha whakatinana ngā waerau me kirihou i roto i te ora rā, whakaaro iwi e ki o ratou awhina e taea te whakaoti tata katoa raruraru, nui rawa hoki ngā rauemi māori. roa tenei euphoria pūtaiao-hangarau, me te matū i te mutunga o nga tekau o nga hitu ahuru, tae noa ki te te taata kia e te miro, rinena huruhuru ranei mo te kakahu, ko te tonu i roto i nuinga o te wā, pai atu i tetahi waihanga. Heoi, e kore i te hunga tekau tau i roto i te noa, he maha 'ulungaanga rawa faufaa, me te whai hua o waerau hanga nga tikanga mo to ratou tono whānui i roto i mara ngā o te mahi a te tangata.

Ko tētahi o te rauemi waihanga tino noa he pareaku. He aha te mea tenei hua mo te hanga o te tahi mau hua te whakamahia reira i teie nei? Hei whakautu i ēnei pātai, me matau tuatahi tetahi nga āhuatanga matū, me te pūkaha o te waerau.

Ka rite ki te rauemi, ko te pareaku mekameka polyether multimolecular. I roto i te ariā o te waerau he kaha here, e hanga i te reira tino kaha. A, no te tono ki te kakahu tenei tikanga tona ātete tiketike ki te haehae me te pae. He pai tenei? O te akoranga, mo etahi o enei mau huru he tuhinga whare paku mahuinga, me te te kaha ki te pato'ii te makuku. Ko nga mea katoa kua he paku. Iti absorption wai, me te pakeke o te rauemi kia fiemālie reira i roto i te pā ana ki te mata kiri. Engari te kōrero e pā ana ki te pareaku e he tino papanga kāore mō te kakahu, e kore koutou e taea e noa he iti tona hōkai.

whenua rerekē i ngā ingoa hokohoko rerekē, whakaritea nei te Pareaku. kia kia ngā Composition o ngā rauemi mata, hei tauira, "65% huruhuru, 35% pareaku." Ko te kupu, ko te, i mawhiti tuatahi, ke, i roto i te meka, he he whakarāpopototanga, e te Academy o Sciences -, "A" me "B" tikanga Academy o Pūtaiao, me nga pukapuka "Ihowa" he taiwhanga o pūhui tiketike-rāpoi. I roto i te US, hua tenei rauemi kei raro i te ingoa "takaaku".

I roto i te hangarau, Kei te whānui whakamahia tenei waerau e tika ana ki te āhuatanga motuhake. Hei tauira, mo te hanga o ngā rauemi tākainga tono kaha nui, whakamahia pareaku whānui. He aha e enei mau huru? Mauroa mō te tightening pēre taraputanga he nui te faaafaro i kaha shock he anake ātete paku iho ki haehae o te Unuhia whakarewa, ai ko nui māmā te waerau me, nui, iti iho te rino. kakawaea kaha pareaku ai ratou tono i roto i te wā i reira kia tino pono te tui, me taura, whatu i a ratou, ka taea e te tu kawenga nui.

I roto i te ao ahumahi rererangi me te hanga waka tekau tau whakamutunga hoki kua kaha whakawhänui i te hōkai o te tono o ngā rauemi polymeric hiato. Tetahi tūemi, ki nei tono hei utu o hokohoko kirihou dural te, te whakaiti taimaha, me te whakapiki i waikura resistance. rererangi Military, tenei pareaku kua tetahi taonga nui: nga kairangahau kitea mau e ui ki te pareaku, reira rauemi radioprovodyaschy. Tenei taonga e āhei ki a koutou te mahi i ana radomes hihiani me riro rererangi silhouette iti kitea ki te hoariri rangi taea korero.
