FC-FR180S Ka mana o ka nalowale o ka wai
Hoʻokumu ʻia ka copolymer sulphonate copolymer (drilling fluid) FC-FR180S ma o ka polymerization multi-step ma lalo o ka hana a ka mea hoʻomaka e ka acrylic amide, acrylic acid, 2-acryloyloxybutyl sulfonic acid (AOBS), epoxy chloropropane a me ka monomer cationic hou. He huahana kēia e kū ana i ka mahana ākea a me ka paʻakai e kū ana i ka pohō wai me ka hana hoʻemi pohō wai maikaʻi loa. Loaʻa iā ia ka hopena hoʻonui viscosity maikaʻi i ka slurry wai hou, a hoʻonui iki i ka viscosity i ka slurry wai paʻakai a hiki ke hoʻohana ʻia ma ke ʻano he ʻākena no ka hoʻonui ʻana i ka viscosity a me ka kaohi pohō wai i nā wai wili paʻa manuahi a haʻahaʻa. Loaʻa i kēia huahana ke kū maikaʻi o ka mahana a me ke kū paʻakai, hiki i ke kū wela ke hiki i 180 ℃, a hiki i ke kū paʻakai ke hiki i ka saturation. He kūpono loa ia no ka wai wili wai kai, ka wai wili lua hohonu a me ka wai wili lua hohonu loa.

1. Hopena kiʻekiʻe, haʻahaʻa mahele lāʻau, hana maikaʻi o ka kaohi ʻana i ka pohō wai.
2. Loaʻa iā ia ke kūpaʻa wela maikaʻi a me ke kūpaʻa wela o 180 ℃, a hiki ke hoʻohana ʻia i loko o nā luawai hohonu a me nā luawai hohonu loa;
3. Loaʻa iā ia ke kūpaʻa paʻakai ikaika i ka saturation a me ke kūpaʻa calcium magnesium, a hiki ke hoʻohana ʻia no ka ʻeli ʻana a me ka hoʻopau ʻana i nā wai i ka wai hou, ka wai paʻakai, ka wai paʻakai saturated a me ka wai kai;
4. He hopena maikaʻi kona e hoʻonui ai i ka viscosity i loko o ka slurry wai maʻemaʻe.
