ʻO ka maʻamau, hana ʻia ʻo VJ Piping me ke kila kila me 304, 304L, 316 a me 316Letc. Ma ʻaneʻi e hoʻolauna pōkole mākou i nā ʻano o nā mea kila kila.
SS304
Hoʻokumu ʻia ʻo 304 stainless steel pipe e like me ke kūlana ʻAmelika ASTM o kahi hōʻailona kila kila.
ʻO 304 paipu kila kila e like me kā mākou 0Cr19Ni9 (OCr18Ni9) paipu kila kila.
Hoʻohana nui ʻia ʻo 304 stainless steel tube e like me ke kila kila i nā lako meaʻai, nā lako kemika maʻamau, a me ka ʻoihana ʻenehana atomic.
ʻO 304 paipu kila kila he paipu kila kila honua, hoʻohana nui ʻia ia i ka hana ʻana i ka hana holoʻokoʻa maikaʻi (corrosion resistance and formability) lako a me nā ʻāpana.
ʻO 304 paipu kila kila ka mea hoʻohana nui ʻia ke kila kila, ke kila wela. Hoʻohana ʻia i nā lako hana meaʻai, nā mea kemika maʻamau, ka ikehu nuklea, etc.
304 paipu kila kuhiliʻole kemika haku mele C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
ʻOkoʻa hana ʻokoʻa 304L a me 304L
304L ʻoi aku ka pale ʻana i ka corrosion, ʻo 304L ka liʻiliʻi o ke kalapona, ʻo 304 he kila kuhili honua, a hoʻohana nui ʻia ia i ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i ka hana piha maikaʻi (ka pale ʻana a me ka formability). ʻO 304L kahi ʻano like ʻole o 304 stainless steel me ka haʻahaʻa carbon content a hoʻohana ʻia no nā noi wili. ʻO ka maʻiʻo kalapona haʻahaʻa e hoʻemi i ka ua carbide i loko o ka wahi wela kokoke i ka weld, hiki ke alakaʻi i ka corrosion intergranular (welding erosion) i ke kila kila ma kekahi mau kaiapuni.
Hoʻohana nui ʻia ʻo 304, me ke kūpaʻa corrosion maikaʻi, ka pale wela, ka ikaika haʻahaʻa haʻahaʻa a me nā waiwai mechanical; ʻO ka hoʻomaʻamaʻa wela maikaʻi, e like me ke kuʻi ʻana a me ke kulou ʻana, me ka ʻole o ka mālama ʻana i ka wela (ʻaʻohe magnetic, me ka hoʻohana ʻana i ka mahana -196 ℃-800 ℃).
He kūpaʻa maikaʻi loa ka 304L i ka corrosion palena o ka palaoa ma hope o ke kuʻi ʻana a i ʻole ka hoʻoluhi koʻikoʻi: hiki iā ia ke mālama i ke kūpaʻa maikaʻi ʻana me ka ʻole o ka mālama ʻana i ka wela, ka mahana hana -196 ℃-800 ℃.
SS316
ʻO 316 kila kila maikaʻi nō hoʻi nā waiwai chloride erosion, no laila hoʻohana mau ʻia ia i nā kaiapuni moana.
ʻO ka hale hana paipu kila kuhiliʻole kūpaʻa
ʻOi aku ka maikaʻi o ka corrosion ma mua o 304 stainless steel, i ka hana ʻana o ka pulp a me ka pepa he kūpaʻa maikaʻi.
A ʻo ka 316 stainless steel ka mea kūʻē i ka moana a me nā ʻenehana ʻoihana koʻikoʻi. ʻO ke kūpaʻa wela ma 1600 degere ma lalo o ka hoʻohana hoʻopau ʻana a ma 1700 degere ma lalo o ka hoʻohana mau ʻana, 316 ke kila kila maikaʻi ke kūpaʻa oxidation.
Ma ka laulā o 800-1575 degere, ʻoi aku ka maikaʻi ʻaʻole e hoʻohana mau i ka 316 stainless steel, akā i ka pae wela ma waho o ka hoʻohana mau ʻana o 316 stainless steel, maikaʻi ke kila kila.
ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316 stainless steel ma mua o ka 316 stainless steel a hiki ke hoʻohana ʻia i ka pae wela o luna.
316 kuhiliʻole kila i maikai kuʻihao hana. Hiki ke wili ʻia me ka hoʻohana ʻana i nā ʻano wili maʻamau āpau. Hiki ke hoʻohana ʻia ka welding e like me ka hoʻohana ʻana o 316Cb, 316L a i ʻole 309CB stainless steel filler rod a i ʻole electrode welding. No ka loaʻa ʻana o ke kūpaʻa corrosion maikaʻi loa, e hoʻopili ʻia ka ʻāpana welded o 316 stainless steel ma hope o ke kuʻi ʻana. ʻAʻole koi ʻia ka hoʻopili ʻana ma hope o ka weld inā hoʻohana ʻia ke kila kila 316L.
Nā mea hoʻohana maʻamau: nā mea hoʻololi wela o ka pulp a me ka pepa, nā mea pena, nā lako hana kiʻiʻoniʻoni, nā paipu, a me nā mea hana no ka waho o nā hale kūlanakauhale ma nā kahakai.
ʻAiʻi ʻino ʻino
Me ka ulu ʻana o ka hoʻokele waiwai, ʻo ke kila kila i ka ʻoihana meaʻai, nā lawelawe ʻai a me ka hoʻohana ʻana i ke ola ʻohana a ʻoi aku ka nui o ka lehulehu, ua manaʻo ʻia ma waho aʻe o ke kila kila kila a me ka papa ʻaina, ʻālohilohi a maʻemaʻe e like me nā hiʻohiʻona hou, akā ua loaʻa pū kekahi. ʻO ka pulupulu maikaʻi loa, antibacterial, ka hana sterilization.
E like me kā mākou e ʻike ai, ʻo kekahi mau metala, e like me ke kālā, ke keleawe, ka bismuth a me nā mea ʻē aʻe he antibacterial, hopena bactericidal, ka mea i kapa ʻia he kila kila antibacterial, i loko o ke kila kila e hoʻohui i ka nui o nā mea me ka hopena antibacterial (e like me ke keleawe. , kālā), ka hana ʻana o ke kila ma hope o ka mālama ʻana i ka wela antibacterial, me ka hana hoʻoponopono paʻa a me ka hana antibacterial maikaʻi.
ʻO ke keleawe ka mea nui o ka antibacterial, ʻo ka nui o ka hoʻohui ʻana ʻaʻole pono e noʻonoʻo i ka waiwai antibacterial, akā e hōʻoiaʻiʻo hoʻi i nā waiwai hana maikaʻi a paʻa o ke kila. ʻOkoʻa ka nui o ke keleawe me nā ʻano kila. Hōʻike ʻia ka haku mele ʻana o ke kila kila antibacterial i hoʻomohala ʻia e Japanese Nissin Steel ma ka Papa 10. Hoʻohui ʻia ka 1.5% keleawe i ke kila ferritic, 3% i ke kila martensitic a me 3.8% i ke kila austenitic.
