ʻO nā ʻāpana Mica e hoʻololi nei i ka ʻoihana Rubber. Ke alakaʻi piha i nā mea hoʻopihapiha hana kiʻekiʻe.
Wehewehe Pōkole:
ʻO nā ʻāpana Mica, me ko lākou ʻano lamellar ʻokoʻa, ke kūpaʻa kemika kūikawā, a me ka hoʻohālikelike kupaianaha me nā matrices rubber, ua hoʻokumu paʻa iā lākou iho he mau mea hoʻopihapiha hana kiʻekiʻe i ka ʻoihana rubber. ʻAʻole e like me nā mea hoʻopihapiha maʻamau e like me ke kalapona ʻeleʻele a i ʻole ka calcium carbonate, hāʻawi nā ʻāpana mica i kahi hui kūikawā o ka hoʻoikaika mechanical, ke kūpaʻa ʻana i ka wā, a me ke kūpaʻa dimensional, e lilo ana iā lākou i koho kūpono no nā huahana rubber e hana ana i nā wahi ʻino, me nā sila kaʻa, nā hose rubber ʻoihana, a me nā kāʻei conveyor.
Ma ke ʻano o nā sila laholio kaʻa, me nā sila puka, nā sila puka makani, a me nā gaskets mīkini, he kuleana koʻikoʻi ko nā ʻāpana mica i ka hoʻoikaika ʻana i ke kūpaʻa ʻana i ka haehae a me ka hana hoʻonohonoho compression. Hoʻopilikia pinepine ʻia kēia mau sila i ke kaumaha mechanical, nā loli wela koʻikoʻi mai -40°C a i 120°C, a me ka lōʻihi o ka hoʻolaha ʻana i ka radiation UV, nā mea e hiki ai ke hoʻoulu i nā sila laholio maʻamau e haki, paʻakikī, a nalowale paha ka elasticity i ka hala ʻana o ka manawa.
ʻO ka hoʻohui ʻana o 8%-15% o nā ʻāpana mica ratio kiʻekiʻe, me ka nui o ka ʻāpana o 30-80 μm a me ka ratio hiʻohiʻona o ≥100, i ka ethylene-propylene-diene monomer (EPDM) rubber e hāʻawi i nā hopena kupaianaha. Hoʻonui ka ikaika haehae o ka rubber ma 40%-60%, ʻoiai ʻo ka helu hoʻonohonoho compression, i ana ʻia ma hope o 70 mau hola ma 100°C, e hāʻule nui ana mai 35% a 15%. Ua hana kahi mea hana ʻāpana kaʻa alakaʻi ma Kelemania i nā hoʻokolohua nui me ka hoʻohana ʻana i kā mākou mau ʻāpana mica i nā sila puka EPDM. He mea kupaianaha nā hopena: ua mālama nā sila i ko lākou elasticity a me ka hana sila no 500,000 mau pōʻaiapuni wehe a pani, hoʻohālikelike ʻia me 300,000 mau pōʻaiapuni no nā sila me ka ʻole o nā ʻāpana mica. ʻAʻole wale kēia ola lawelawe i hoʻonui ʻia e hōʻemi i nā kumukūʻai mālama no nā mea nona nā kaʻa akā hoʻonui pū i ka hilinaʻi holoʻokoʻa o nā huahana kaʻa.
ʻO Mica ka inoa maʻamau o nā minelala hui mica. ʻO ia ka aluminosilicate o ka potassium, alumini, magnesium, hao, lithium a me nā metala ʻē aʻe, nā mea a pau he papa a monoclinic. He pseudohexagonal lamellae a i ʻole e like me ka pā ke kristal, i kekahi manawa he kolamu. Ua piha loa ka ʻoki lamellar, me ka luster aniani a me ka pepa elastic. Hoʻonui ka index refractive o mica me ka hoʻonui ʻia o ka nui o ka hao, mai ka protrusion haʻahaʻa a i ka protrusion waena. ʻO ke ʻano me ka ʻole o ka hao he kala ʻole i loko o ka flake. ʻO ke kiʻekiʻe o ka nui o ka hao, ʻoi aku ka ʻeleʻele o ke kala, a ʻoi aku ka polychromatic a me ka absorptive.
Ka nui o ka ʻāpana Mica: 6-10mesh, 10-20mesh,
Pauka Mika: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh a me 5000mesh.

I ka ʻoihana, hoʻohana nui ka biotite i kona pale ʻana a me ke kūpaʻa wela, a me ke kūpaʻa waikawa, ke kūpaʻa alkali, ke kūpaʻa compression a me ke kūpaʻa peeling, ma ke ʻano he mea pale o nā lako uila a me nā lako uila; ʻo ka lua, hoʻohana ʻia e hana i nā puka makani a me nā ʻāpana mechanical o nā paila mahu a me nā umu hoʻoheheʻe. Hiki ke hana ʻia nā ʻāpana Mica a me ka pauka mica i pepa mica, a hiki ke pani i ka pepa mica e hana i nā mea pale like ʻole me ke kumu kūʻai haʻahaʻa a me ka mānoanoa like.
ʻO Muscovite ka mea i hoʻohana nui ʻia i ka ʻoihana, ukali ʻia e ka phlogopite. Hoʻohana nui ʻia ia i ka ʻoihana mea kūkulu hale, ʻoihana kinai ahi, mea kinai ahi, koʻokoʻo wili, palakiko, insulation uila, hana pepa, pepa asphalt, rubber, pigment pearlescent a me nā ʻoihana kemika ʻē aʻe.
Hoʻohana ʻia ka pauka mica Ultrafine ma ke ʻano he mea hoʻopihapiha hana no ka plastic, pena, pena, laholio a pēlā aku, hiki ke hoʻomaikaʻi i kona ikaika mechanical, hoʻoikaika i ka paʻakikī, ka hoʻopili ʻana, ka anti-aging a me ke kūpaʻa ʻana i ka corrosion.
