Tuhinga o muaNapathalene te tino pai o te wai whakaheke i te kaihoko:

(1).Napathalene I pania ki te pāmahana tiketike (160 ~ 165 ℃), te nuinga o te waikawa β-naphthanene sulfonic, engari he iti ano hoki o te waikawa naphthalene.

(2). Tāpirihia te wai hei hanga i te α-ephthalne whanariki waikawa hydrolyze, hanga β-naphthalene pikinga tipu waikawa;

(3). β-naphthalene pūkawa pūkawa me te waikawa formaldehyde;

(4) Te whainga.

Te hangarau tono oNaphthalene Te Whakanuitanga o te wai whakaheke:

1.Ko te kaha o te timatanga me te raima kaha kua rite. I te whakaranu i te 0.5% ~ 1%Napathalene te tino pai o te wai whakaheke i te kaihokoE ai ki te taumaha o te raima, ka taea te whakaheke i te wai kia 16% 25%, me te kaha o te raima e taea ai e te 20% ~ 50% (te kaha o te raima e piki ake ana).
2.Ko te whakaritenga o te raima rere nui, i te wa eNaphthalene Te Whakanuitanga o te wai whakahekeMo te inenga cement o te 0.2% ~ 0.5%, ko te kaha o te raima ka huri, ka taea te piki haere o te raima ki te 10 ~ 25cm, ka taea te tere o te ahunga whakamua, me whakapai ake i te kounga hanga.
3.Teneke, i raro i te ahuatanga o te pupuri i te kaha o te raima kaore e heke, ko te taapiri i te 0.5%Napathalene te iti o te wai whakahekeKa taea te whakaora i te raima mo te 20%.
