【Hoʻolauna】: Ma ke ʻano he waiwai kālepa nui, pili loa ke ʻano o ka mākeke kūloko o ka sulfur i ka mākeke honua. E lawe ʻo Xiaobian iā ʻoe e hoʻomaopopo i ke kūlana o ka mākeke honua o ka sulfur ma o ka nānā ʻana i nā kumukūʻai mākeke honua o ka sulfur, ka waikawa sulfuric a me ka mea hoʻoulu phosphate.

1. Piʻi aʻe ke kumukūʻai o ke kālā honua

I ka makahiki 2023, ua piʻi iki ka mākeke kālā ʻAmelika, i hoʻokele mua ʻia e ka mākeke RMB, ua hoʻomaka ʻia ka mākeke kūʻai mea hoʻouluulu Kina i Iune, a ukali ʻia e ka mākeke mea hoʻouluulu honua i Iulai, a ua hoʻonui ʻia ke kumukūʻai ʻaelike o Qatar a me Kuwait i ʻAukake e 19/18 kālā US/tona i 82/80 kālā US/tona, a ua piʻi mālie ke koi metala Indonesia. I ka lā 10 o ʻAukake, ʻo ka ʻaoʻao lawe mai: FOB Vancouver US $89 / tona, FOB Middle East US $89.5 / tona, i piʻi 27.5/26 US $/ tona mai Iulai, ʻo ka ʻaoʻao hoʻokuʻu aku: CFR India $102.5 / tona, CFR Kina $113 / tona, i piʻi 16.5/113 / tona mai Iulai. ʻO ke kumukūʻai ikaika o ke kālā US ma ka sulfur honua e hāʻawi i ke kākoʻo nui i ka mākeke RMB.

2, ua piʻi aʻe ka hoʻokuʻu aku ʻana o Kina i ka waikawa sulfuric i Indonesia ma 229.6%

Ma ke ʻano he alakaʻi pololei i lalo o ka sulfur, ka mākeke sulfuric acid honua synchronous sulfur mai ka maikaʻi ʻole a i ka maikaʻi, ʻo ka lawe ʻana mai o ka sulfuric acid i ka hapa mua o kēia makahiki he 175,300 tons, he piʻi ʻana o 16.79% ma mua o ka manawa like i ka makahiki i hala, ʻo ia ke kumu nui no Iapana a me Kōlea Hema a me ka Panalāʻau ʻo Taiwan, nona ka 96.6% o ka lawe ʻana mai o ka sulfuric acid e Shandong, Jiangsu i loaʻa, ʻo ka lako nui ma lalo o nā ʻoihana kemika maikaʻi nui, a pēlā aku. Eia kekahi, ʻo ka hapa nui o ka sulfur wai ma Shandong/Jiangsu he lōʻihi loa ia, no laila ua paʻa pono ke koi o ka mākeke. Ma ke ʻano o nā mea hoʻokuʻu aku, ʻo ka lawe ʻana aku o ka sulfuric acid o Kina i ka hapa mua o ka makahiki he 1,031,300 tons, he emi ʻana o 55.83% ma mua o ka manawa like i ka makahiki i hala, i hoʻouna nui ʻia i Indonesia, Saudi Arabia, Chile a me India, a ma muli o ke koi no nā papahana metala ma Indonesia, ua hiki ka ulu ʻana o ka hoʻokuʻu aku i 229.6% ma mua o ka makahiki i hala.

3, ʻo ka hoʻonui ʻia ʻana o ke kūʻai ʻana o ka mea hoʻoulu phosphate honua e hoʻokele i ke kumukūʻai o nā mea maka

Ma ke ʻano o ka mea hoʻoulu phosphate ma hope, ʻoiai ʻo ia ka mea lawe nui loa o ka mea hoʻoulu phosphate ma ka honua, ua lawe mai ʻo India i ka huina o 1.04 miliona tons i Iune, he piʻi ʻana o 283.76%, me ka hopena o ka ua nui ma Asia Hikina Hema i kēia makahiki, ua koi ʻia ʻo Thailand, Bangladesh a me Vietnam a me nā ʻāina ʻē aʻe e hoʻonui i ke kūʻai ʻana i ka mea hoʻoulu phosphate honua, a ua hoʻomaka ka mākeke honua e hoʻonui koke i nā kumukūʻai phosphate. I kēia manawa, ʻo ka uku DAP honua ma CFR530-550 US kālā/ton, a ʻo ke kumukūʻai kiʻekiʻe o ka mea hoʻoulu phosphate ke kumu kūʻai o ka sulfur maka, a ke kū nei ka mākeke sulfur honua. Eia nō naʻe, i kēia manawa, ua hoʻemi mālie ʻia ka mākeke urea honua, a e loli ke ʻano o ka noi no ka mākeke mea hoʻoulu.

4, ka mākeke honua ikaika e hoʻokele ai i ka wā hea?

Mai Iune, ma muli o ka mana o nā kumu he nui, ʻo ke kumukūʻai sulfur honua ma ke ala, me ka mākeke sulfuric acid ma lalo a me ka piʻi ʻana o ke koi phosphate fertilizer honua, ua kōkua pū i ka hoʻohui ʻana o kēia puni o ka piʻi ʻana o ke kumukūʻai, i ka wā pōkole, kākoʻo koi, mākeke sulfur maʻalahi, ka hiki ke mālama i kahi ʻano piʻi; I ka wā lōʻihi, e nāwaliwali mālie ka wela o ka mākeke phosphate fertilizer ma lalo i ka wā fertilizer hāʻule i Kepakemapa, a e paʻa ana ke koi no nā mea maka a me nā huahana kiʻekiʻe, akā ʻo ka hoʻomaka ʻana o ka mālama ʻana i ka hoʻoilo kūloko e hiki ke hoʻomaopopo ʻia. Manaʻo ʻia e hoʻopaʻa ʻia a hoʻoluliluli ʻia ka mākeke honua sulfur i ka wā ma hope.
