Te Whakamahinga o te Kakahu Kotahi-Ahunga o te Muka Pātara i roto i ngā Mahi Whakakaha Hanganga
Mahi tino pai:
muka pātaratihe pai ngā āhuatanga ā-tinana, he pai te piri, he ātete ki te wera me te Ātete ki te Waikura, me ētahi atu, he tino pai mō te mara o te miihini ā-iwi.
muka pātarati Ehara i te mea he kaha kume teitei anake te kakahu kotahi-ahunga, engari he pai hoki te roa (3.1%). Ka taea e ia te mimiti i te nui o te pūngao mā te whakarerekētanga ohorere ina pakaru i raro i te āhua rohe, nō reira he mahi ahurei, he mahi pai hoki mō te whakapakari rū whenua. Ko te kakahu kotahi-ahunga muka basalt he rauemi ārai kore-arataki. I roto i ngā kauhanga raro whenua, ngā ara rerewē hiko me ētahi mahi ārai-aukume, ārai-hiko, ārai-aukume o te kaupapa whakapakari whare, he tino kitea ngā painga o te kakahu kotahi-ahunga muka basalt. Tāpiri atu ki tēnā.kakahu kotahi-angihanga muka basalt He tino watea hoki te hanganga o te kaupapa whakapakari, ā, he pai ake te whakakotahitanga o te piripiri, he teitei ake te uruhanga o te kapia ki roto i te muka waro, kia pai ake ai te ātete o te hanganga whare ki te nekehanga me te ātete pānga, he pai mō te whakapakari i ngā piriti, ngā puke, ngā pou, ngā kurupae me ētahi atu wāhanga o te piriti.
Mahi hangarau:
1. Ātete pānga: te kaha kume o te muka basalt tonu o te 4100 ~ 4800MPa, te modulus o te ngāwari o te 90 ~ 110GPa, te roa mutunga o te 3.1% (muka waro 1.7%, miro 2.4%), i roto i te rohe o te kaha taumaha, ko te rauemi muka basalt te tuatahi ki te mimiti i te nui o te kaha mā te whakarerekētanga, koinei tētahi o ngā āhuatanga e hiahiatia ana i roto i te kaupapa whakapakari whare. Nō reira, he whānui te whakamahinga o te muka basalt i roto i ngā taputapu hōia, ngā whare ātete-pahū, me ngā kaupapa whakapakari tauranga piriti.
2. Ātete ki te ngenge kawenga hihiri: Ahakoa he teitei te kaha kume o te muka waro, he pai te tu atu ki te kawenga mata mō te wā roa, engari i te āhua taumahatanga mutunga kore, kāore te muka waro e pai mō te pakarukaru, te ātete kawenga hihiri, te ātete ngenge ki te muka basalt, nō reira i roto i te whakapakari hanganga, inā koa te whakapakari piriti, he ātete-ru whenua te whakapakari. Me whakamahi rauemi rerekē i ngā wāhanga rerekē, ko ētahi me whakamahi muka waro, ko ētahi me whakamahi muka basalt.
3. Ātete waikawa, ātete kawakore, ātete matū: he pai te ātete waikawa me te ātete kawakore o te rauemi muka basalt, i roto i te 1000C i roto i te wairewa kua whakakiia ki te Ca (OH) 2 mō ngā haora e 4, he nui ake te tere pupuri kaha o te monofilament i te 75.8% neke atu rānei, ā, he pai te ātete ki te kawakore kaha, he pai te ātete waikawa. Nā te mea he katote chlorine o te wai moana i te takutai moana, he kaha te waikura matū o te hanganga raima o te tauranga moana, ka arahi pea ki te waro o te raima, te waikura o te maitai whakapakari, nō reira mā te whakamahi i ngā uaua muka basalt, te kakahu kotahi-ara mō te whakapakari ka taea te whakatutuki i ngā hua pai ake.
4. Ngā āhuatanga pai o te ārai hiko: muka pātarati He pai ake te whakamarumaru i te muka karāhe alkali, he kaiārahi hiko te muka waro, nō reira i roto i ngā kaupapa tereina raro whenua, kaupapa kauhanga, kaupapa rerewē hiko, tipu ahumahi, me ngā whakaritenga whakamarumaru o ngā whare teitei, mā te whakamahi i te whakapakari muka basalt ka taea te whakakore i te āhuatanga tiaki.
Painga utu:
Kakahu muka pātara kotahi-angi I roto i te whakamahinga o te whakapakari hanganga, he iti te mahi a te muka waro, he nui ake rānei, ā, ko te utu mō ia mita tapawha o te muka basalt he 1/4-1/3, koinei te huarahi tino whaitake ki te whakakapi i te muka waro he kakahu kotahi te utu.
