ʻO ke ʻano synthesis onaphthalene kiʻekiʻe ka hana hoʻohaʻahaʻa wai:

(1).Naphthalene ua sulfonated i ke kiʻekiʻe wela (160 ~ 165 ℃), hana nui i ka β-naphthalene sulfonic acid, akā he wahi liʻiliʻi o nā naphthalene sulfonic acid;

(2). Hoʻohui i ka wai e hoʻoheheʻe i ka waika α-naphthalene sulfonic hydrolyze, e hoʻonui i ka ʻike o ka β-naphthalene sulfonic acid;

(3). β-naphthalene sulfonic acid a me formaldehyde condensation;

(4) Hoʻokuʻu ʻia.

ʻO ka ʻenehana noiʻi onaphthalene kiʻekiʻe ka hana hoʻohaʻahaʻa wai:

1. Ua hoʻomākaukauʻia ka ikaika mua a me ka ikaika kiʻekiʻe. I ka hui ʻana i ka 0.5% ~ 1%naphthalene kiʻekiʻe ka hana hoʻohaʻahaʻa waie like me ke kaumaha o ka sima, hiki ke hoemiia ka wai e 16% ~ 25%, a hiki ke hoonui i ka ikaika o ka oihana e pili ana i ka 20% ~ 50% (ua hoonuiia ka ikaika mua o ke kaa.
2.The hoʻomākaukau o ka nui kahe kahe ana, i ka wa o kanaphthalene kiʻekiʻe ka hana hoʻohaʻahaʻa waino ka sima dosage o 0.2% ~ 0.5%, ka ikaika o ke kaʻa ka hoʻololi 'ole, hiki ke hoʻonui i ka slump o ka palaki i 10 ~ 25cm, hoʻohana 'ia no ka gravity grouting, pumping concrete, hiki ke hoʻoikaika i ka holomua o ka hana, hoʻomaikaʻi i ka maikaʻi o ka hana.
3.ave sima, ma lalo o ke kūlana o ka mālama 'ana i ka ikaika o ke kaʻaʻaʻole emi, hoʻohui ma kahi o 0.5%naphthalene mea hoemi wai kuponohiki ke mālama i ka sima ma kahi o 20%.
