Ma keʻano he hoʻokahi o nā mea hoʻolako kemika nui loa ma Shandong Province, Kina, aia mākou i mua o ka hoʻolakoʻana i nā huahana kiʻekiʻe kiʻekiʻe mai ka makahiki 2000. ʻO kā mākouʻoihana kūikawā i ka hoʻolakoʻana i nā mea hana kemika a me nā mea waena koʻikoʻi uaʻae iā mākou e mālama i nāʻanoʻoihana likeʻole. Ma waena o nā kemika koʻikoʻi a mākou e hāʻawi nei ʻo Methylene Chloride, Propylene Glycol (PG), a me Dimethylformamide (DMF). He kuleana koʻikoʻi kēia mau pūhui i nā kaʻina hana like ʻole, e hoʻolilo iā lākou i mea nui i kā mākou mea kūʻai aku.
Hoʻohana nui ʻia ʻo Methylene Chloride, i ʻike ʻia no kāna mau mea hoʻoheheʻe, i ka wehe ʻana i ka pena, degreasing, a ma ke ʻano he mea kōkua i ka hana ʻana i nā lāʻau lapaʻau. ʻO kona maikaʻi i ka hoʻoheheʻe ʻana i nā ʻano mea like ʻole ke koho maikaʻi ʻia i nā noi ʻoihana he nui. Ma ka ʻaoʻao ʻē aʻe, ʻo Propylene Glycol (PG) he mea hoʻohui like ʻole e lawelawe ana ma ke ʻano he humectant, solvent, a me ka mālama ʻana i ka meaʻai, nā mea hoʻonaninani, a me nā lāʻau lapaʻau. ʻO kona ʻano ʻawaʻawa ʻole a me kona hiki ke mālama i ka makū, lilo ia i mea waiwai nui i nā ʻano hana he nui. He mea koʻikoʻi ʻo Dimethylformamide (DMF), he polar aprotic solvent, i ka hana ʻana i nā fibers synthetic, plastics, a me nā lāʻau lapaʻau, e hāʻawi ana i ka solubility maikaʻi loa no kahi ākea o nā pūhui organik a me ka inorganic.
Me kā mākou hale kūʻai ponoʻī a me kahi kaulahao hoʻolako oʻo, hōʻoia mākou e loaʻa i kā mākou mea kūʻai aku kēia mau huahana kemika ma nā kumukūʻai hoʻokūkū me ka ʻole o ka hoʻohālikelike ʻana i ka maikaʻi. ʻO kā mākou kūpaʻa i ka maikaʻi a me ka ʻoluʻolu o ka mea kūʻai aku ua hoʻokumu iā mākou ma ke ʻano he hoa hilinaʻi i ka ʻoihana kemika. Ke hoʻomau nei mākou i ka hoʻonui ʻana i kā mākou hāʻawi ʻana, hoʻomau mākou i ke kākoʻo ʻana i kā mākou mea kūʻai aku me nā lako maka e pono ai lākou e hana hou a holomua i kā lākou mau mākeke. Inā makemake ʻoe i ka Methylene Chloride, PG, DMF, a i ʻole nā mea hana kemika ʻē aʻe, eia mākou e hoʻokō i kāu mau pono me ka maikaʻi a me ka maikaʻi.
