He momo rauemi kore-whakarewa kore-waro te muka karāhe, he tino pai te mahi, he maha ngā painga ko te pai o te whakamarumaru, te kaha ki te wera, te pai o te ātete ki te waikura, te kaha miihini teitei, engari ko te ngoikoretanga ko te pakarukaru, te ngoikore o te ātete ki te kakahu. Ko ngā rauemi mata matua mō te hanga muka karāhe ko: te onepu quartz, te alumina me te pyrophyllite, te kōhatu kōhatu, te dolomite, te waikawa boric, te pungarehu houra, te glauberite, te fluorite me ētahi atu. E rua ngā wāhanga o te tikanga hanga: ko te tuatahi ko te hanga tika i te karāhe kua hanumi hei muka; ko te tuatahi ko te hanga i te karāhe rewa hei pōro karāhe, hei tokotoko rānei he 20mm te whānui, kātahi ka hanga he muka tino pai he 3-80 te whānui.μm i muri i te whakamahana me te whakarewa anō i roto i ngā momo huarahi. Ko te muka mutunga kore i tuhia mā te tikanga tuhi miihini mā roto i te pereti konukōre konukōre ka kiia ko te muka karāhe tonu, e mōhiotia whānuitia ana ko te muka roa. Ko te muka kore-tonu i hangaia e te roera, e te rere hau rānei ka kiia ko te muka karāhe roa-pūmau, e mōhiotia whānuitia ana ko te muka poto. Ko te diameter o ōna monofilaments he maha ngā maikorona ki te neke atu i te rua tekau maikorona, he rite ki te 1/20-1/5 o te makawe tangata, ā, ko ia paihere o ngā miro muka he rau, he mano rānei ngā monofilaments. Ko te muka karāhe te tikanga e whakamahia ana hei rauemi whakapakari i roto i ngā rauemi hiato, ngā rauemi whakamahana hiko me ngā rauemi whakamahana wera, ngā panera rori me ētahi atu mara o te ōhanga ā-motu.
Ko ngā āhuatanga o te muka karāhe e whai ake nei:
(1) He kaha kume teitei, he iti te toronga (3%).
(2) He nui te tauwehenga ngāwari, he pai hoki te pakari.
(3) He roa te whakaroa me te kaha kume teitei i roto i te rohe rapa, nō reira he nui te mimiti o te kaha pānga.
(4) He muka kore-waro, kāore e mura, he ātete matū pai.
(5) He iti te mimiti wai.
(6) He pai te pumau o te unahi me te ātete ki te wera.
(7) He pai te tukatuka, ka taea te hanga hei miro, hei paihere, hei huruhuru hipi, hei papanga whatu me ētahi atu momo hua rerekē.
(8) Mārama te māramatanga.
(9) He pai te ngāwari ki te whai me te kapia.
(10) He iti te utu.
(11) Ehara i te mea ngāwari ki te tahu, ā, ka taea te whakarewa hei pīrori karāhe i ngā pāmahana teitei.
