1. He aha te muka karāhe?
muka karāhee whakamahia whānuitia ana nā te mea he iti te utu me ngā āhuatanga pai, ko te nuinga i roto i te umanga hiato. I te rautau 18, i mōhio ngā Pākehā ka taea te miro i te karāhe hei muka mō te raranga. Kua oti kē te whakakī i te kāwhena o te Emepara Wīwī a Napoleon ngā papanga whakapaipai i hangaia kimuka karāheHe miro, he miro poto, he miro rānei ngā muka karāhe. He mea whakamahi noa ngā miro karāhe i roto i ngā rauemi hiato, ngā hua rapa, ngā whitiki kawe, ngā tāpaurini, me ētahi atu. Ko ngā muka poto te mea e whakamahia nuitia ana i roto i ngā whatu kore-whatu, ngā kirihou hangarau me ngā rauemi hiato.
Ngā āhuatanga ā-tinana, ā-pūkaha hoki o te muka karāhe, te ngāwari o te hanga, me te iti o te utu ki te whakataurite kimuka waromeinga ai hei rauemi whiriwhiri mō ngā tono hiato mahi-teitei. He mea hanga ngā muka karāhe i ngā waikura o te silica. He tino pai ngā āhuatanga miihini o ngā muka karāhe pērā i te iti o te pakarukaru, te kaha teitei, te iti o te pakari me te mama.
Ko ngā pūmua whakakaha muka karāhe he momo nui o ngā momo muka karāhe rerekē, pērā i ngā muka roa, ngā muka tapatapahi, ngā whāriki whatu, mewhāriki miro tapatapahi, ā, e whakamahia ana hei whakapai ake i ngā āhuatanga ā-pūkaha me ngā āhuatanga tribological o ngā hiato polymer. Ka taea e ngā muka karāhe te whakatutuki i ngā ōwehenga āhuatanga tīmatanga teitei, engari ka taea e te pakarukaru te pakaru o ngā muka i te wā e tukatukahia ana.

Te kore e taea te ngāwari:Nā te kore e ngāwari, kāore e tino totoro, e tino ora ake rānei te papanga. Nō reira, me atawhai te mata kia kore ai e miro.
Kaha Teitei:He tino kaha te muka karāhe, tata rite tonu te kaha ki te Kevlar. Heoi, ina mirimiri ngā muka tetahi ki tetahi, ka whati, ka āhua huruhuru te papanga.
Te whakamarumaru:I te whakarapopototanga, he tino pai te karāhe muka hei ārai i te wera.
Te Āhuatanga o te Tākai:He pai te taupee o ngā muka, he mea tino pai mō ngā ārai.
Ātete Wera:He tino ātete ngā muka karāhe ki te wera, ka taea te tu atu i ngā pāmahana tae atu ki te 315°C, kāore hoki e pāngia e te rā, e te wai mā, e te huakita, e te harore, e ngā pepeke, e te kawakore rānei.
Ngāwari:Ka pāngia ngā muka karāhe e te waikawa hauwaiwai me te waikawa whākawa wera. Nā te mea he hua karāhe te muka, me āta tiaki te whakahaere i ētahi muka karāhe mata, pērā i ngā rauemi whakamahana whare, nā te mea he pakarukaru ngā pito muka, ā, ka taea te wero i te kiri, nō reira me mau karapu ina whakahaere ana i te muka karāhe.
3. Te tukanga hanga muka karāhe
muka karāhehe muka kore-whakarewa e whakamahia whānuitia ana i tēnei wā hei rauemi ahumahi. Ko ngā rauemi mata taketake o te muka karāhe ko ngā kohuke taiao me ngā matū hanga-tangata, ko ngā wāhanga matua ko te onepu silica, te kōhatu me te pungarehu houra.
He mea hanga karāhe te onepū silica, ā, he mea āwhina te pungarehu houra me te kōhatu iti ki te whakaiti i te pāmahana rewa. Nā te iti o te tauwehenga o te whānui wera me te iti o te kawe wera ki te whakataurite ki te asbestos me ngā muka rauropi, ka noho te muka karāhe hei rauemi pumau ā-ahu e tere ai te whakamarara i te wera.
muka karāheka puta mai mā te rewa tika, e uru ana ki ngā tukanga pēnei i te whakaranu, te rewa, te miro, te paninga, te whakamaroke, me te takai. Ko te puranga te āhua tuatahi o te hanga karāhe, e whakaranua pai ana ngā rahinga rauemi, kātahi ka tukuna te ranunga ki te oumu hei rewa i te pāmahana teitei o te 1400°C. He rawaka tēnei pāmahana hei huri i te onepu me ētahi atu kai ki te āhua rewa; kātahi ka rere te karāhe rewa ki te mīhini whakapai ka heke te pāmahana ki te 1370°C.
I te wā e mirohia ana ngā muka karāhe, ka rere te karāhe rewa mā roto i tētahi ringaringa he kōhao angiangi rawa. Ka whakamahanahia te pereti arai mā te hiko, ā, ka whakahaeretia tōna pāmahana kia mau tonu te matotoru. I whakamahia he pupuhi wai hei whakamatao i te miro i tōna putanga mai i te ringaringa i te pāmahana tata ki te 1204°C.
Ko te awa o te karāhe rewa ka kumea mā te miihini ki roto i ngā miro, he whānui mai i te 4 μm ki te 34 μm. Ka whakaratohia te kukū mā te whakamahi i te mīhini hurihuri tere-rahi, ā, ka kumea te karāhe rewa ki roto i ngā miro. I te wāhanga whakamutunga, ka pania ngā paninga matū o ngā hinu whakahinuhinu, ngā here me ngā kaihoko honohono ki ngā miro. Ka āwhina te whakahinuhinu ki te tiaki i ngā miro mai i te pakū i a rātou e kohia ana, e takaihia ana ki roto i ngā kete. I muri i te rahi, ka whakamaroketia ngā muka ki roto i te oumu; kātahi ka rite ngā miro mō te tukatuka anō ki ngā muka tapatapahi, ki ngā miro hurihuri, ki ngā miro rānei.
4.te whakamahinga o te muka karāhe
muka karāhe He rauemi kore-waro tēnei e kore e mura, ā, e mau tonu ana te 25% o tōna kaha tuatahi i te 540°C. He iti noa te pānga o te nuinga o ngā matū ki ngā muka karāhe. Kāore te muka karāhe kore-waro e pokepokea, e pirau rānei. Ka pāngia ngā muka karāhe e te waikawa hauwaiwai, te waikawa whākawa wera me ngā matū kawakore kaha.
He rauemi ārai hiko tino pai rawa atu tēnei.Ngā papanga muka karāheHe iti ngā āhuatanga o ēnei mea pērā i te mimiti makuku iti, te kaha nui, te ātete wera me te iti o te pūmau dielectric, ā, he mea tino pai ēnei hei whakakaha mō ngā papa ara iahiko tā me ngā wanihi whakamahana.
Nā te ōwehenga kaha-ki-taumaha teitei o te muka karāhe, he rauemi pai rawa atu tēnei mō ngā tono e hiahia ana kia kaha nui me te iti o te taumaha. I roto i te āhua kakahu, ka taea te ahunga kotahi, te ahunga rua rānei o tēnei kaha, e āhei ai te ngāwari o te hoahoa me te utu mō te whānuitanga o ngā tono i roto i te mākete motuka, te hanganga ā-iwi, ngā taonga hākinakina, te rererangi, te moana, te hikohiko, te kāinga me te pūngao hau.
Ka whakamahia hoki ēnei i roto i te hanga i ngā hanganga hiato, ngā papa hiko tā me ngā hua motuhake. Ko te whakaputanga muka karāhe ā-tau o te ao e tata ana ki te 4.5 miriona tana, ā, ko ngā kaihanga matua ko Haina (60% o te hea mākete), te Hononga o Amerika me te Kotahitanga o Ūropi.
