Ngā Mica Flakes e Hurihuri Ana i te Ahumahi Rapa He Aratohu Whānui ki ngā Whakakī Mahi-Tiketike

Whakaahuatanga Poto:

Ko ngā kongakonga mika, me ō rātou hanganga lamellar motuhake, te pumau matū tino pai, me te hototahi whakamiharo ki ngā matrices rapa, kua tino whakapumautia rātou hei whakakī mahi teitei i roto i te umanga rapa. He rerekē ki ngā whakakī tikanga pērā i te waro pango, te konupūmā waro rānei, ka tukuna e ngā kongakonga mika he huinga ahurei o te whakapakari miihini, te ātete ki te huarere, me te pumau o ngā āhuatanga, ka waiho hei whiringa pai mō ngā hua rapa e mahi ana i roto i ngā taiao uaua, tae atu ki ngā hiri motuka, ngā ngongo rapa ahumahi, me ngā whitiki kawe.

I roto i te ao o ngā hiri rapa motuka, tae atu ki ngā hiri kuaha, ngā hiri matapihi, me ngā gasket miihini, he mea nui ngā kongakonga mika ki te whakapakari i te ātete ki te haehae me te mahi a te huinga pēhanga. Ka pāngia ēnei hiri e te ahotea miihini maha, ngā piki me ngā heke o te pāmahana mai i te -40°C ki te 120°C, me te roa o te wā e pāngia ana e te hihi UV, arā, ngā āhuatanga ka pakaru, ka whakapakeke, ka ngaro rānei te ngāwari o ngā hiri rapa noa i roto i te wā.

Mā te tāpiri i te 8%-15% o ngā kongakonga mika teitei te ōwehenga, me te rahi matūriki o te 30-80 μm me te ōwehenga āhua o te ≥100, ki te rapa ethylene-propylene-diene monomer (EPDM) ka puta he hua whakamiharo. Ka piki ake te kaha haehae o te rapa mā te 40%-60%, ko te tere whakatakoto kōpeketanga, i inehia i muri i te 70 hāora i te 100°C, ka heke nui mai i te 35% ki te 15%. I whakahaerehia e tētahi kaihanga wāhanga motuka matua i Tiamana he whakamātautau whānui mā te whakamahi i ā mātou kongakonga mika i roto i ngā hiri tatau EPDM. He mea whakamiharo ngā hua: i mau tonu te ngāwari me te mahi hiri o ngā hiri mō te 500,000 huringa whakatuwheratanga me te kati, ki te whakaritea ki te 300,000 huringa noa iho mō ngā hiri kāore he kongakonga mika. Ko tēnei roanga o te ora ratonga ehara i te mea ka whakaiti noa i ngā utu tiaki mō ngā kaipupuri waka engari ka whakarei ake hoki i te pono whānui o ngā hua motuka.

Mō ngā ngongo rapa ahumahi e whakamahia ana hei whakawhiti i ngā matū, te hinu, me te wai, he mea nui ngā maramara mika hei whakapakari i te ātete matū me te ātete ki te pēhanga. He maha ngā wā ka pā atu ēnei ngongo ki ngā mea waikura, ā, me tu atu ki ngā pēhanga ā-roto teitei tae atu ki te 10 MPa. Ko ngā maramara mika, me tō rātou hanganga lamellar kore e uru, ka hanga he ārai whai hua i roto i te anga rapa, ka whakaiti i te urunga o ngā matū mā te 50%-70%.

Ina tāpirihia ki ngā ngongo rapa nitrile (NBR) i te horopeta o te 10%-20%, ka whakanuia e ngā kongakonga mika te pēhanga pakū o te ngongo mā te 25%-35%, ā, ka roa ake tōna roanga mahi i roto i ngā tono whakawhiti hinu mai i te 1 tau ki te 2-3 tau. I whakamatautauria ā mātou ngongo NBR kua whakapakarihia ki te mika e tētahi wheketere matū i Netherlands i roto i te whakawhiti o te waikawa whanariki kukū 20%. He tino pono ngā hua: i muri i te 12 marama o te whakamahinga tonu, kāore i whakaatuhia e ngā ngongo he tohu pupuhi, he turuturu rānei, engari ko ngā ngongo NBR paerewa i rahua i muri i te 4 marama noa iho. Hei tāpiri, ka whakapai ake ngā kongakonga mika i te pumau o ngā āhua o ngā ngongo rapa, ka whakaiti i te whakahekenga i te wā o te whakamomona mā te 15%-25% me te whakarite kia tika te uru ki ngā hononga.

E tutuki ana ā mātou kongakonga mika katoa i ngā paerewa ahumahi pakari e pā ana ki ngā tohu hangarau matua. Ko te nui o te makuku he ≤0.3%, ko te nui o te pungarehu he ≤0.5%, ko te mimiti hinu he ≤25 mL/100g, ā, he tino pai te ātete ki te wera, ka noho pumau i ngā pāmahana tae atu ki te 600°C. Hei tāpiri, e tutuki katoa ana ā mātou hua i ngā ture RoHS me REACH, me te nui o te konganuku taumaha kei raro iho i ngā rohe haumaru o te ao (mata ≤0.0005%, āheniki ≤0.0003%).

Mō ngā mahi kawe waka, ko te kounga me te pono o ā mātou hua te mea nui ki a mātou. Ko ā mātou kongakonga mika he mea takai ki roto i ngā putea ātete-makuku (25 kg/pēke), he kiriata polyethylene o roto, he putea pepa kraft o waho hei ārai i te mimiti o te makuku i te wā e kawe ana i te moana. Kua whakatūria e mātou he hononga kaha ki ngā kamupene kaipuke matua pērā i a Maersk me COSCO, kia tere ai te tuku ki ngā kiritaki i Ūropi, Amerika Te Raki, me Āhia ki te Tonga-mā-rāwhiti i roto i ngā rā 15-30.

Ngā Tohu Hua

Ko te mika te ingoa whānui o ngā kohuke o te rōpū mika. Ko te aluminosilicate o te pāhare pāporo, te konumohe, te konupūmā, te rino, te lithium me ētahi atu konganuku, he paparanga katoa, he monoclinic. He rite te karaihe ki te pereti he rite ki te lamellae hexagonal, he poupou rānei i ētahi wā. He tino oti te wehenga o te lamellae, me te kanapa karāhe me te pepa rapa. Ka piki ake te taupū whakaata o te mika me te pikinga o te ihirangi rino, mai i te iti o te putanga ki te waenga o te putanga. Ko te momo kāore he rino he kore tae i roto i te maramara. Ko te teitei ake o te ihirangi rino, ko te pouri ake o te tae, ā, ko te maha o ngā tae me te mimiti.

Rahi o te kongakonga mika: 6-10 mata, 10-20 mata,
Paura mika: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh me te 5000mesh.

I roto i te umanga, ko te biotite te mea nui hei rauemi whakamahana me te ātete wera, tae atu ki te ātete waikawa, te ātete kawakore, te ātete pēhanga me te ātete kiri, hei rauemi whakamahana mō ngā taputapu hiko me ngā taputapu hiko; tuarua, ka whakamahia hei hanga i ngā matapihi me ngā wāhanga miihini o ngā kohua mamaoa me ngā oumu whakarewa. Ka taea te tukatuka i ngā maramara mika me te paura mika hei pepa mika, ā, ka taea hoki te whakakapi i te pepa mika hei hanga i ngā rauemi whakamahana iti te utu me te matotoru ōrite.

Ko te Muscovite te mea e whakamahia whānuitia ana i roto i ngā ahumahi, ā, whai muri ko te phlogopite. E whakamahia whānuitia ana i roto i ngā ahumahi rauemi hanga, ahumahi tinei ahi, kaihoko tinei ahi, tokotoko whakarewa, kirihou, whakamahana hiko, hanga pepa, pepa uku, rapa, tae peara me ētahi atu ahumahi matū.

Ka whakamahia te paura mika tino pai hei whakakī mahi mō te kirihou, te peita, te peita, te rapa me ētahi atu, ka taea te whakapai ake i tōna kaha miihini, te whakapakari i te pakari, te piri, te ārai i te koroheketanga me te ātete ki te waikura.
