Kua tīmata ngā whakahoutanga i te haurua tuarua o te tau, ā, he nui ngā whakahoutanga e arotahi ana i te marama o Hūrae-Ākuhata, ā, kua tīmata te heke o ngā taonga mata. Hei tāpiri, i whakaputa ētahi kaihanga rauemi mata nui i ngā pānuitanga mō ngā āhuatanga kāore i te tika, ā, i whakararuraru i te iti o ngā taonga o te mākete.

Kua mutu! Ngā mahi tiaki i Wanhua, BASF, Covestro me ētahi atu āhuatanga kino!

I whakaputa a Wanhua Chemical i tētahi pānuitanga whakamutu mahi whakaputa i te 6 o Hūrae, e kī ana ka tīmata te mahi whakaputa me te tiaki i te 10 o Hūrae, ā, e matapaetia ana ko te roa o te tiaki he 25 ngā rā.

Hei tāpiritanga, he maha ngā taputapu pūwero MDI kua taka ki roto i te mana kore, ā, kua kati mō te tiaki.

▶Covestro: i te 2 o Hūrae i panuitia ai te kaha o te taputapu MDI 420,000 tāne/tau i Tiamana, 330,000 tāne/tau MDI i te Hononga o Amerika me ētahi atu hua;

▶Huntsman: He maha ngā wā i tirotirohia ai, i whakatikatikaina ai hoki mai i Poutū-te-rangi ki Hune, ā, i tēnei wā, ko te nuinga o ngā whakaurunga i te kāinga me tāwāhi kei te pāka tonu;

▶I whakahoutia ngā taputapu MDI o BASF, Dow, Tosoh, Ruian me ētahi atu wheketere nui, ā, i mutu te hanga.

Ko Wanhua Chemical, BASF, Huntsman, Covestro, me Dow te hunga e 90% o te kaha whakaputa MDI o te ao. Ināianei kei roto ēnei taputapu matua i ngā āhuatanga rerekē, ā, kua mutu katoa te whakaputa, kua mutu hoki te whakaputa. Kua tino heke te whakaputanga. He tino pōturi te mākete MDI. Kua piki ake ngā utu mākete tetahi i muri i tetahi. I te mea me whai ake te hekenga iho, ka piki ake ngā kaipupuri, ā, ka piki ake te utu mō te rā kotahi mā te 100-350 yuan/tana. E matapaetia ana ka piki ake te MDI i te haurua tuarua o te tau.

Kua ara ake ngā whakaaro o ngā toa nunui! Tērā pea ka puta ngā hua i te hauwhā tuatoru!
Kua piki haere tonu te whakamutua o te hanga me te tiaki i ngā wheketere nui, ā, kua heke anō ngā taonga o te mākete. I tēnei wā, kua tīmata te piki haere o ngā hua matū hangarau-teitei, he nui te mana whakahaere i roto i te mākete.

E ai ki te rārangi ahumahi matū i ngā rā e 5 kua pahure ake nei, e 38 ngā hua matū katoa kei te piki haere. Ko ngā pikinga matua e toru ko: te polymeric MDI (9.66%), te waikawa formic (7.23%), me te propane (6.22%).

Nā te pumau o ngā utu ā-motu kua hoki mai ngā utu o te nuinga o ngā hua matū ki te taumata tika. Heoi, nā te pikinga ake o ngā whakahoutanga matua me te maha o ngā āhuatanga ohorere, kua tīmata te mākete ki te manukanuka mō te korenga o te koura, te iwa me te hiriwa, ā, kua tīmata ētahi kaihokohoko ki te hoko taonga i ngā utu iti i te wā kore utu. E matapaetia ana ka tūpono te korenga o ngā taonga i te hauwhā tuawhā, ka piki ake rānei ngā utu mākete. Ināianei kei te aroturuki mātou i te mākete matū i te wā kore utu, me te hoko taonga i te wā tika.
