Kānana Pā Nui | Nā Hoʻonā Kānana Kiʻekiʻe no nā ʻAla a me nā ʻAla
ʻO ka hana ʻana o nā mea ʻono a me nā mea ʻala e hilinaʻi nei i ka kānana pololei e hōʻoia i ka maʻemaʻe, ka maopopo, a me ke kūpaʻa o ka huahana. Ua māhele ʻia ke kaʻina hana kānana i kekahi mau pae, i hoʻolālā ʻia kēlā me kēia e hoʻokō i nā koi kūlana kikoʻī. Kānana ʻAʻahu: Wehe i nā ʻĀpana Nui ʻO ka hana mua, ʻo ia ka hoʻopau ʻana i nā ʻāpana nui e like me nā olonā mea kanu, ka resin, a me nā ʻōpala, e kū mai ana ma hope o ka unuhi ʻana a i ʻole ka dist... -
Ke Kaʻina Kānana Silicone me nā Kānana Great Wall: Ke Hōʻoiaʻiʻo nei i ka Maʻemaʻe a me ka Pono
ʻO ka hope Silicones he mau mea kū hoʻokahi e hoʻohui ana i nā waiwai o nā hui inorganic a me nā mea olaola. Hōʻike lākou i ka haʻahaʻa o ka ʻili, ka coefficient viscosity-temperature haʻahaʻa, ke kiʻekiʻe o ka compressibility, ke kiʻekiʻe o ka permeability gas, a me ke kūpaʻa maikaʻi loa i nā wela kiʻekiʻe, ka oxidation, ka weathering, ka wai, a me nā kemika. ʻAʻole lākou he ʻawahia, physiologically inert, a loaʻa iā lākou ka maikaʻi loa... -
Kānana ʻana o ka Pā Nui ma ka Electroplating: Maʻemaʻe no nā hoʻopau kiʻekiʻe
Kānana ʻana i nā Kaʻina Hana Electroplating I ke ao o ka electroplating, ʻoi aku ka nui o ka kānana ma mua o ke kaʻina hana kākoʻo—he kihi ia o ka maikaʻi. I ka hoʻohana pinepine ʻia ʻana o nā ʻauʻau plating no nā metala e like me ka nickel, zinc, keleawe, tin, a me chrome, hōʻiliʻili mau lākou i nā mea haumia i makemake ʻole ʻia. Hiki i kēia mau mea ke komo pū me nā mea āpau mai nā ʻōpala metala, nā ʻāpana lepo, a me ka sludge a hiki i nā ad organik i palaho... -
Nā Hoʻonā Kānana Pā Nui no ka Epoxy Resin
Hoʻolauna i ka Epoxy Resin ʻO ka resin Epoxy kahi polymer thermosetting i ʻike ʻia no kona hoʻopili maikaʻi loa, ka ikaika mechanical, a me ke kūpaʻa kemika. Hoʻohana nui ʻia ia i nā uhi, ka insulation uila, nā mea hui, nā mea hoʻopili, a me ke kūkulu ʻana. Eia nō naʻe, hiki i nā mea haumia e like me nā mea kōkua kānana, nā paʻakai inorganic, a me nā ʻāpana mechanical maikaʻi ke hoʻopilikia i ka maikaʻi a me ka hana o ka resin epoxy.... -
Nā Hoʻonā Kānana Pā Nui no ka Cellulose Acetate
He mea hana maʻalahi ka Cellulose acetate me nā ʻano hana like ʻole. I ka ʻoihana paka, ʻo ka cellulose acetate tow ka mea maka mua no nā kānana cigarette ma muli o kāna hana kānana maikaʻi loa. Hoʻohana ʻia hoʻi ia i ka ʻoihana kiʻiʻoniʻoni a me nā plastics no ka hana ʻana i nā kiʻiʻoniʻoni kiʻi, nā mōlina hiʻohiʻona, a me nā lima hana. Eia kekahi, lawelawe ka cellulose acetate ma ke ʻano he mea nui... -
Nā Hoʻonā Kānana Pā Nui no ka Hana ʻana i ka Fiber Polyester
Hoʻolauna i ka kānana ʻili polyester ʻO ka fiber polyester kekahi o nā olonā synthetic koʻikoʻi o ka honua, e hana ana i ke kuamoʻo o nā ʻoihana mai ke ʻano a hiki i nā lole ʻoihana. ʻO kona ikaika, ka lōʻihi, a me ke kumukūʻai kūpono e lilo ia i koho kiʻekiʻe no nā lole, nā upholstery, nā kāpeti, a me nā noi loea. Eia nō naʻe, ʻo ka hoʻokō ʻana i nā olonā polyester kiʻekiʻe ʻaʻole ia he automated...
