Ka Nānā ʻana i ka ʻenehana papa hui ʻekolu-i-hoʻokahi Rubber-Ceramic: Nā Mea Hana, Nā Kaʻina Hana a me nā Noi ʻOihana

Ma ke kahua o ke kūpaʻa ʻana i ka ʻaʻahu ʻoihana, ʻaʻole lawa nā hoʻonā kuʻuna hoʻokahi mea e hoʻokō ai i nā koi paʻakikī o ke kapa kiʻekiʻe a me ka hopena ikaika i nā kūlana hana like ʻole. ʻO ka papa hui ʻekolu-i-hoʻokahi rubber-ceramic, ma ke ʻano he hopena kipi, ua hoʻokō i kahi holomua i ka hana mea ma o kahi hoʻolālā hoʻonohonoho hui ʻekolu papa: kūʻē ka papa keramika i ka ʻaʻahu, omo ka papa rubber i ka hopena, a hāʻawi ka papa kila i ke kākoʻo. Hoʻohana nui ʻia kēia mea kūpaʻa ʻaʻahu hui i nā ʻoihana kaumaha e like me ka mana, ka mining, a me ka metallurgy, a ua lilo ia i hoʻokahi o nā ʻenehana koʻikoʻi no ka hoʻolōʻihi ʻana i ke ola o nā lako a me ka hōʻemi ʻana i nā kumukūʻai mālama.

ʻO kapā hui ʻekolu-i-hoʻokahi me ka laholio-ceramicUa haku ʻia me nā keramika pale ʻaʻahu, ka laholio a me nā papa kila metala. Hoʻohana nui ka papa keramika i ka pauka alumina maʻemaʻe kiʻekiʻe (92%, 95%) ma ke ʻano he mea maka, i hana ʻia ma ke kaomi maloʻo a i ʻole ke kaomi isostatic. Ma hope o ka sintered ʻia ʻana ma kahi mahana kiʻekiʻe loa o 1700°C, ua hoʻokumu ʻia kahi ʻano paʻa me ka paʻakikī Mohs o 9 a me ka nui o ≥ 3.65 g/cm³. A laila, ua laminated ʻia ka keramika pale ʻaʻahu alumina a me ka papa laholio a waiho ʻia i loko o ka ʻōmole. Hana ʻia kahi hopena vulcanization (140-160°C) ma lalo o ke ana wela kiʻekiʻe a me ke kaomi kiʻekiʻe. Hoʻokumu nā molekala laholio i nā pilina kemika me ka ʻili keramika. Ma mua o ka vulcanization, ua kau ʻia kahi papa kila ma luna o ka laholio, a ua hoʻopaʻa ʻia nā papa ʻekolu ma o ka vulcanization lua.

Hiki ke hoʻopili ʻia ka papa hui ʻekolu-i-hoʻokahi me ka rubber-ceramic, me kāna hana koʻikoʻi, i nā hiʻohiʻona aʻe:

1. Hiki ke hoʻohana ʻia i nā ʻōnaehana hana mea kiʻekiʻe-ʻaʻahu, e like me ka hopper o kahi mīkini wili mining a i ʻole ka chute sintering o kahi wili kila. Hiki iā ia ke kū i ka ʻino ʻana o nā mea ʻoi e like me ka hao hao a me ke one quartz, a ʻoi aku kona ola lawelawe ma mua o ʻelima mau manawa o nā papa kila maʻamau.

2. Kūpono no nā hiʻohiʻona i maʻalahi i ka makū a me ka paheʻe, e like me ka pahu lawe lanahu o nā kāʻei conveyor awa a me ka uapo, a me nā mea hoʻoili kāʻei i nā hale hana meaʻai. Hāʻawi nā ʻāpana seramika i loko o ka pā rubber-ceramic ʻekolu-i-hoʻokahi i ka ikaika friction kiʻekiʻe. ʻO ke koina kū'ē paheʻe pulu he ≥ 0.5, e pale ana i nā mea mai ka paheʻe ʻana.

3. He kūpono ia no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe a me nā wahi ʻino, e like me ke kaula hoʻoili wela i nā wili kila (nā bila kila ʻulaʻula ma 200 ℃), a me nā pahu holoi waikawa i nā hale hana kemika. Hiki i ka laholio kūpaʻa wela a me nā keramika inert ke pale pono i ka hoʻoili wela a me ka ʻino kemika.

4. No nā wahi me nā ʻokoʻa hāʻule nui, e like me nā paipu hoʻokuʻu lanahu i nā mea kanu mana wela (me ka ʻokoʻa hāʻule ma luna o 20 mika) a me nā silos mea maka i nā mea kanu sima, hoʻohana ʻia nā keramika pale ʻaʻahu e hoʻopuehu i ka ikaika hopena, a hoʻohana ʻia nā papa laholio no ka omo ʻana i ka haʻalulu e pale ai i nā papa ʻaʻahu mai ka nahā ʻana.

Mai nā lua mina a i nā awa, mai nā wili kila a i nā hale hana mana, ua wehewehe hou ka papa hui ʻekolu-i-hoʻokahi rubber-ceramic i ke kūlana pale ʻaʻahu ʻoihana me kahi ʻano pale ʻekolu. ʻAʻole wale kona waiwai i kona ola he 10 makahiki (ʻoi aku ma mua o nā mea kuʻuna ma 3-5 mau manawa), akā i loko o ka mālama kālā nui i loaʻa ma ka hōʻemi ʻana i ka downtime a me ka mālama ʻana. Me ka hoʻokomo ʻana o nā mea hou a me nā kaʻina hana akamai, e hoʻomau kēia ʻenehana hui i ka hoʻokele ʻana i ka ulu ʻana o nā lako ʻoihana kaumaha i ke kūpaʻa kiʻekiʻe, ka hoʻohana ʻana i ka ikehu haʻahaʻa, a me nā hiʻohiʻona mālama ʻole.
