Kei te matatau te mahi a ngā rāngai parepare me te rererangi ki te pūtaiao rauemi, me te tono i ngā wāhanga ka taea te tu atu i ngā āhuatanga tino kino—mai i te wera nui me te tango i ngā matū ki ngā kaha-G teitei me te pānga matū. I tēnei taiao nui, ko ngā **pūhui whakakikorua phenolic (PMC) kua whakapakaritia ki ngā miro tapatapahi** kei te kitea he otinga tino nui.

I hangaia mō te pito rawa

Ko ngā kapia phenolic, he momo pūmua whakawerawera, e mōhiotia whānuitia ana mō tō rātou pumau wera, te ōritetanga o ngā āhuatanga, me te ātete ki te mura. Ina whakakotahitia ēnei kapia ki ngā miro tapatapahi tino tika, tino pai (he maha ngā wā he muka karāhe, he muka silica rānei), ka hangaia he rauemi hiato i hangaia mō ngā tono tino uaua.

Mā te whakaurunga o ngā miro tapatapahi ki roto i te ranunga whakapūtanga ka whakakaha ake, ka huri i ngā āhuatanga o te rauemi:

* **Ātete Pai ki te Whakakorenga:** I roto i te rererangi me te mahi roketi, ka pāngia ngā wāhanga e ngā pāmahana wera. He maha ngā wā ka whakamahia ngā PMC whakapakari i roto i ngā **pūrere roketi, ngā pare wera, me ngā rūma mura** nā te mea ka ātete ki te whakakorenga (te horo o te mata i te wera) me te pupuri tonu i te hanganga pai i raro i ngā āhuatanga mura.

* **Kaha me te Pūmautanga o te Mahana-Teitei:** Kāore ngā phenolics thermoset e rewa, he rerekē ki ngā kirihou wera. Ka maukati ngā miro tapatapahi i te kapia kua whakamaroketia ki tōna tūranga, ka tino pai te **ātete ki te ngoki** me te **pakari** ahakoa ngā pāmahana neke atu i te 300°C (ā, i ētahi wā he nui ake i ngā mahi tango).

* **Whakaritenga mō te Ahi, te Auahi, me te Paitini (FST):** Mō ngā kaipuke hōia, ngā waka rererangi, me ngā hanganga matua, he mea nui te haumaru. He iti te whakaputanga paowa** me te **paitini** o ngā matū phenolic ina pāngia e te ahi, ā, he mea pai mō ngā whare, ngā paipa hiko, me ngā panera hiato kei reira te haumaru o te tangata e āwangawangatia ana.

Ngā Whakamahinga Matua mō te Hoia me te Rererangi

Te maha o ngā āhuatangangā PMC kua whakakahangia ki te aho tapatapahika taea ai te whakamahi i a rātou i roto i ngā tūranga mahi tino nui:

* **Ngā Wāhanga o te Rōkete me te Peretā:** Whakamahia hei whakamahana i ngā wāhanga o te anga o te motuka me ngā korokoro o te pūwero hei whakahaere i ngā kawenga wera nui i te wā whakarewatanga.

* **Ngā Āhuatanga me ngā Hanganga o te Rererangi:** Ngā wāhanga mō ngā waka rererangi, he mea nui te āhua mama o te rauemi me te tutuki i ngā whakaritenga FST mō te haumaru o ngā kaimahi me ngā taputapu.

* **Ngā Rauemi Waku:** Whakamahia i roto i ngā pūnaha aukati mō ngā waka whenua hōia taumaha me ngā waka rererangi nā te mea he tino ātete ki te wera me te mahi pakaru.

* **Ngā Whare Hiko me te Hikohiko:** Nā te kaha teitei o te dielectric me te pumau o ngā āhuatanga, he mea tino pai mō te pupuri i ngā taputapu hiko tairongo me mahi pono i roto i ngā taiao hikohiko, pāmahana rānei.

Te Painga o te Matū Whakakotahi Tapatapahi

He painga nui te hanga wāhanga mai i tētahi matū whakahāngai tapatapahi i roto i te hanga parepare: **ngāwari hoahoa.** Ka taea te whakahāngai i te matū ki te pēhi, ki te werohanga rānei kia puta he āhua uaua, he āhua koretake e uaua ana ki te whakatutuki mā te whakamahi i ngā muka whakahāngai tonu. Mā tēnei kaha ki te whakahāngai i ngā wāhanga uaua, kaha, me te tino pakari ki ngā whakaritenga hōia ka whakaū i te mana o te rauemi hei mea matua mō te hangarau hōia me te rererangi matatau.

He aho whakakaha kounga teitei a China Beihai kua tapatapahia, e tutuki ana i ngā paerewa pakari o te umanga parepare. Whakapā mai ki a mātou kia mōhio ai koe me pēhea e taea ai e ā mātou rauemi te whakarei ake i te mahi me te pono o ō wāhanga tino nui.
