ʻO ke kila kila kila maikaʻi e pili ana i nā mea kila kila e pili ana i ka National Standard of the People's Republic of China / Sanitary Standards for Stainless Steel Utensil Containers GB 9684-88. ʻOi aku ka haʻahaʻa o ke kēpau a me ka chromium ma mua o ke kila kuhiliʻole maʻamau.
Ke hoʻohana ʻia nā metala kaumaha ma mua o ka palena, hiki ke hoʻopilikia i ke olakino kanaka. Ma muli o kēia, ua hoʻonohonoho ka National Food Safety Standard o "Stainless Steel Products" (GB9684-2011) i nā kūlana koʻikoʻi no ka ua o nā metala kaumaha like ʻole e like me ka chromium, cadmium, nickel, a me ke alakaʻi i nā mea kuke. ʻO kekahi kumu ʻo ia me ka hoʻonui ʻana o ka manganese i loko o ke kila kila, ua nalowale nā hana e like me ka pale ʻana i ka corrosion a me ka pale ʻana o ka mea kuke. Ke hiki i ka ʻike manganese i kahi waiwai, ʻaʻole hiki ke hoʻohana ʻia kēia huahana ma ke ʻano he kuke a ʻaʻole hiki ke kapa ʻia he mea kuke kila kila. Akā ʻoiai me kēlā ʻano manganese kiʻekiʻe, ʻaʻohe hopena olakino. ʻO ka 304 stainless steel he kila kila maʻamau, i kapa ʻia ʻo 18-8 stainless steel i ka ʻoihana. ʻOi aku ka maikaʻi o kona kūpaʻa ʻana ma mua o ka 430 stainless iron, kiʻekiʻe corrosion kū'ē, a kiʻekiʻe-mehana kūpaʻa, maikaʻi ka hana hana, no laila ua hoʻohana nui ia i ka ʻoihana, mea hoʻonani hale, a me ka ʻoihana lapaʻau, no ka laʻana, kekahi mau mea kila kila kila kiʻekiʻe. hale ʻauʻau, hale kīhini.
No ka mālama ʻana i ke kūpaʻa ʻino o ke kila kila, pono e loaʻa ka kila ma mua o 17% chromium a ʻoi aku ma mua o 8% nickel. I ka hoʻohālikelike, 201, 202 stainless steel (ʻike nui ʻia ʻo ke kila manganese kiʻekiʻe) ke hoʻohana maʻamau ʻia i nā huahana ʻoihana a ʻaʻole hiki ke hoʻohana ʻia e like me ka papa ʻaina, no ka mea: ʻoi aku ka nui o ka manganese ma mua o ka maʻamau, ʻoi aku ka nui o ka manganese i loko o ke kino o ke kanaka. ʻo ka ʻōnaehana nerve.
I ke ola o kēlā me kēia lā, loaʻa iā mākou ke kūlana kiʻekiʻe loa o ka hoʻopili ʻana i nā huahana kila kuhiliʻole, a ʻo nā ipu uila kila kila kekahi o lākou. He paʻakikī ke hoʻokaʻawale i nā mea ʻo “201″? ʻO wai ka "304"?
No ka hoʻokaʻawale ʻana i kēia mau mea kila kila, ʻo ke ʻano o ka hale hana ke ʻike nui i ka hoʻohui ʻana o nā mea. Aia kekahi ʻokoʻa nui i ka haku mele ʻana o nā mea like ʻole o ke kila kila. No nā mea kūʻai maʻamau, ʻoi aku ka ʻoihana a ʻaʻole kūpono kēia ʻano, a ʻo ka mea kūpono loa ke hoʻohana ʻana i kahi mea hoʻāʻo ʻike manganese 304. Pono e hāʻule ma luna o ka ʻili e ʻike inā he ʻano manganese ka mea ma mua o ka maʻamau, a laila e hoʻokaʻawale ai i ka 201 stainless steel a me 304 stainless steel. A no ka ʻokoʻa ma waena o ke kila kila 304 maʻamau a me ke kila kila kila, ʻoi aku ka nui o ka hoʻāʻo ʻana o ka hale hana e ʻike ai. Akā, pono mākou e ʻike ʻo ka hoʻokumu ʻana o ka meaʻai-grade stainless steel ʻoi aku ka paʻakikī, ʻoiai ʻoi aku ka maʻalahi o ke kila kila ʻoihana.
mea i kūpono i ka palapala hōʻoia maʻamau GB9684 aupuni a hiki ke hoʻopili maoli me ka meaʻai me ka ʻole o ka pōʻino kino. ʻO ke kila kila GB9864 he mea kila kila e kū ana i ka palapala hōʻoia maʻamau GB9684 aupuni, no laila ʻo GB9864 stainless steel ka meaʻai-grade stainless. I ka manawa like, ʻaʻole koi ʻia ka mea i kapa ʻia ʻo 304 stainless steel e hōʻoia ʻia e ka pae aupuni GB9684. ʻAʻole like ke kila kila 304 me ke kila kila kila. ʻAʻole hoʻohana wale ʻia ʻo 304 stainless steel i nā lako kīhini akā hoʻohana nui ʻia i ka ʻoihana. I ka manawa kūʻai, e hōʻailona ʻia nā huahana maʻamau me ka "meaʻai 304 stainless steel" ma ka ʻili a me ka paia o loko o ka huahana, a ʻoi aku ka palekana o nā huahana i hōʻailona ʻia me ka "food grade-GB9684".
