He maikaʻi ʻole ka maikaʻi o nā kīʻaha thermos?

Ma hope o ka hōʻike ʻia ʻana o nā kīʻaha thermos "make", ʻokoʻa loa nā kumukūʻai. He ʻumi yuan wale nō ke kumukūʻai o nā mea liʻiliʻi, a ʻo nā mea kūʻai aku ke kumukūʻai a hiki i nā kaukani yuan. He maikaʻi ʻole ka maikaʻi o nā kīʻaha thermos? Aia nā kīʻaha thermos pipiʻi i ka ʻauhau IQ?

I ka makahiki 2018, ua hōʻike ʻo CCTV i 19 mau ʻano kīʻaha thermos "make" ma ka mākeke. Ma hope o ka ninini ʻana i ka waika hydrochloric i loko o ke kīʻaha thermos a waiho ʻia no 24 mau hola, hiki ke ʻike ʻia ka nui o nā metala manganese, nickel a me chromium i loko o ka waikawa hydrochloric.

He mau metala kaumaha kēia ʻekolu. ʻO ka nui o kā lākou ʻike e alakaʻi i ka haʻahaʻa haʻahaʻa, ka ʻili allergies, a me ka hoʻoulu ʻana i ka maʻi kanesa. Hoʻopilikia nui lākou i ka poʻe ʻelemakule a me nā keiki, a hiki ke hoʻoulu i ka dysplasia a me ka neurasthenia.

ʻO ke kumu i loaʻa ai kēia mau metala kaumaha i loko o ke kīʻaha thermos no ka mea, ua hana ʻia kona pahu i loko i ʻekolu mau mea kila kila maʻamau, ʻo ia ka 201, 304 a me 316.

ʻO 201 kila kila he kila kila ʻoihana me ka haʻahaʻa haʻahaʻa o ka chromium a me ka nickel content. Eia nō naʻe, hiki ke ʻōpala i nā wahi haʻahaʻa a hiki ke ʻino i ka wā e ʻike ʻia ai i nā mea ʻawaʻawa, no laila e hoʻokahe i nā metala kaumaha. ʻAʻole hiki ke pili me ka meaʻai a me nā mea inu no ka manawa lōʻihi.

ʻO ke kila kila 304 ka mea maʻamau i manaʻo ʻia he ʻano meaʻai a hiki ke hoʻohana ʻia e hana i ka liner o kahi kīʻaha thermos; ʻO 316 kila kila he kila kila kila, ʻoi aku ka palekana a ʻoi aku ka pale ʻana i ka corrosion.

I mea e mālama ai i nā kumukūʻai, koho pinepine kekahi poʻe kālepa hewa ʻole i ke kila kila 201 liʻiliʻi loa e like me ka liner o loko o ke kīʻaha thermos. ʻOiai ʻaʻole maʻalahi kēlā mau kīʻaha thermos e hoʻokuʻu i nā metala kaumaha i ka wā e hoʻopiha ai i ka wai wela, ua maʻalahi lākou i ka pōʻino ke hoʻopili ʻia me nā mea inu ʻawaʻawa a me nā wai. ʻO ka ʻino, ka hopena i nā metala kaumaha nui loa.

Manaʻo nā kuʻuna pili aupuni e hiki ke hoʻolapalapa ʻia ke kīʻaha thermos kūpono i ka 4% acetic acid solution no 30 mau minuke a hoʻonā no 24 mau hola, a ʻaʻole ʻoi aku ka nui o ka neʻe ʻana o ka chromium metala ma mua o 0.4 mg/decimeter square. Hiki ke ʻike ʻia ʻo nā kīʻaha thermos haʻahaʻa e pono e hoʻokō i nā kūlana o ka hiki ke mālama pono i nā mea inu kalapona, ma mua o ka ʻae ʻana i nā mea kūʻai aku e mālama i ka wai wela wale nō.

Eia nō naʻe, ʻo kēlā mau kīʻaha kīʻaha thermos kūpono ʻole ma ka mākeke i hana ʻia me ke kila kila kila haʻahaʻa haʻahaʻa, ʻeleʻele kila a i ʻole ke kila i hoʻohana ʻia, e hōʻino i ke olakino kanaka.

ʻO ke kī, ʻo nā kumukūʻai o kēia mau kīʻaha thermos ʻaʻole nā ​​huahana maʻalahi. ʻOi aku kekahi ma mua o ʻumi a i ʻole iwakālua yuan, a ʻoi aku ke kiʻekiʻe o kekahi me hoʻokahi a ʻelua haneli yuan. Ma ka ʻōlelo maʻamau, lawa ka 100 yuan no nā ʻoihana e hoʻohana i nā mea palekana e hana i nā kīʻaha thermos. ʻOiai inā ʻaʻohe koi kūikawā no ka hopena insulation, hiki i nā ʻumi o yuan ke hana holoʻokoʻa.

Eia nō naʻe, ʻoi aku ka nui o nā kīʻaha thermos i kā lākou hana insulation thermal, e hāʻawi ana i nā mea kūʻai aku i ka manaʻo he palekana loa kā lākou huahana. Ke koho ʻana i kahi kīʻaha thermos ma ka mākeke, pono mākou e hoʻolohe a hoʻāʻo e koho i kahi hōʻailona kaulana iki. Eia nō naʻe, aia nā kīʻaha thermos me SUS304 a me SUS316 ma ka pahu i loko.

I ka manawa like, pono ʻoe e nānā inā aia nā hōʻailona o ka ʻōpala i loko o ke kīʻaha thermos, inā he laumā a translucent ka ʻili, inā he ʻala ʻē aʻe, a pēlā aku. a ʻaʻole hiki ke ʻala ke hōʻoiaʻiʻo ʻaʻole e pala ka mea a ua hana ʻia ke kila kuhili ʻole.

ʻOkoʻa nā kumukūʻai o nā kīʻaha thermos i kēia manawa ma ka mākeke. Hoʻohana nā kīʻaha thermos liʻiliʻi i ka ʻenehana hoʻokuʻu huelo a loaʻa kahi keʻena huelo huna ma lalo no ka mālama ʻana i ka wela, akā lawe lākou i kahi ākea a hoʻemi i ka hiki ke mālama wai.

Hoʻopau pinepine nā kīʻaha thermos pipiʻi i kēia hoʻolālā. Hoʻohana maʻamau lākou i ka liner stainless steel austenitic māmā a ʻoi aku ka ikaika (no ka SUS304 stainless steel). Mālama kēia ʻano kila kila i ka ʻike o ka chromium metala ma 16% -26%, hiki ke hana i kahi kiʻiʻoniʻoni pale o ka chromium trioxide ma ka ʻili a loaʻa ke kūpaʻa ikaika.

Eia nō naʻe, ʻo kēlā mau kīʻaha thermos ma ka mākeke e kūʻai aku ana ma mua o 3,000 a 4,000 yuan i kēlā me kēia me nā pahu i loko i hana ʻia me ka titanium alloy. ʻO ka hopena insulation o kēia mea like me ke kila kila. ʻO ke kī ʻo ia ka palekana loa, no ka mea, ʻaʻole kumu ka titanium i ka make metala kaumaha. Eia naʻe, ʻaʻole pono kēia kumukūʻai no ka hapa nui o nā kānaka.

ʻO ka ʻōlelo maʻamau, ʻaʻole i manaʻo ʻia ka hapa nui o nā kīʻaha thermos i ka ʻauhau IQ. Ua like kēia me ke kūʻai ʻana i ka ipuhao ma ka home. ʻAʻole hewa ka ipu hao e kūʻai ana i mau haneli kālā i ka ʻāpana, akā e piʻi aʻe ka nui o ka loaʻa ʻana o nā huahana haʻahaʻa. ʻAʻole kūpono kahi huahana kumu kūʻai kiʻekiʻe i ka makemake o ka hapa nui o nā kānaka. Hoʻohui pū ʻia, kūʻai aku i nā huahana i kūʻai ʻia ma 100-200 yuan ka koho o nā poʻe he nui.
