Ua ʻike nā kānaka a pau e pili ana i nā mea kōkua hana PVC. He aha nā pilikia me nā mea kōkua hana PVC ma ka ʻoihana?

1. Lohi ka ʻenehana MBS a me ka hoʻomohala ʻana, a ākea ka mākeke, akā haʻahaʻa ka māhele mākeke o nā huahana kūloko.

ʻOiai ua hala ma mua o 20 mau makahiki o ka hoʻomohala ʻana, ʻo ka ʻoihana MBS kūloko i kēia manawa wale nō i kona wā kamaliʻi, a ʻaʻohe huahana o nā hui e hiki ke hoʻokūkū piha me nā huahana haole e like me nā mea kōkua hana PVC. Ke kū nei ka hapa nui o nā ʻoihana e kū nei i kahi moʻo o nā pilikia e like me ke koho pono ʻole o nā lako, nā kaʻina hana synthesis paʻa ʻole, a me ka nele o nā holomua i ka ʻenehana synthesis. ʻOiai ʻo ka hapa nui o nā ʻoihana ʻaʻohe o lākou lako synthesis styrene butadiene latex ponoʻī a hiki ke kūʻai wale i ka styrene butadiene latex ʻaʻole MBS no ka hana ʻana o MBS, a hiki ke noʻonoʻo ʻia ke ʻano o kā lākou huahana. I kēia manawa, ʻo ka hapa nui o nā huahana i hoʻolauna ʻia i ka mākeke e hilinaʻi nei i nā pono kumukūʻai a hoʻopili ʻia i nā huahana PVC ʻaʻole pono ke ʻano huahana kiʻekiʻe. Ma ka mākeke kiʻekiʻe, he liʻiliʻi ka māhele mākeke a ʻaʻole i hoʻokumu i kahi hopena i nā ʻoihana haole. Manaʻo ʻia ʻo ka nui o ka lawe mai i ka makahiki 2006 ma waena o 50000 a me 60000 tons, e helu ana ma mua o 70% o ka nui o ke koi.

2. He kakaikahi nā kānaka noiʻi a me nā ʻoihana noiʻi, ka mea i hāʻule ʻole i ka hoʻokumu ʻana i kahi pūʻali koa no nā holomua ʻepekema a me ka ʻenehana.

ʻOiai ua helu ʻia ʻo MBS ma ke ʻano he papahana noiʻi ʻepekema a me ka ʻenehana aupuni i nā manawa he nui, ʻaʻole naʻe i hoʻokō i nā holomua koʻikoʻi. ʻO ke kumu nui, ʻo ia ka emi ʻana o nā mea noiʻi a me ka emi ʻana o ka hoʻopukapuka kālā i ka ʻenehana. I kēia manawa, he mau ʻoihana noiʻi ʻoihana nō ia e hana nei i nā hoʻokolohua kūʻokoʻa a e ʻimi ana i nā holomua, akā hiki ke manaʻo ʻia kēia kumu hoʻohālike noiʻi a me ka hoʻomohala ʻana he amateur i hoʻohālikelike ʻia me nā hui haole a me nā hui noiʻi ʻepekema nui.

3. I kēia manawa, ua kokoke ka pae o nā mea kōkua hana PVC ma Kina i ko nā huahana haole, akā ma muli o nā palena kumukūʻai o CPE, he paʻakikī ke hoʻolaha iā lākou. ʻO ka hele ʻana i ka honua a me ka hoʻokūkū me nā huahana haole no ka mākeke honua he koho maikaʻi ia. Eia nō naʻe, ʻo ka huahana hoʻokahi o kēia manawa a me ka paʻa ʻole o ka paʻa e lilo i mea wikiwiki no nā poʻe loea o ka ʻoihana e hoʻoponopono.
