The kaphatikizidwe njira yanaphthalene mkulu dzuwa kuchepetsa wothandizira:

(1).Naphthalene anali sulfonated pa kutentha kwambiri (160 ~ 165 ℃), makamaka kupanga β-naphthalene sulfonic acid, komanso pang'ono ena naphthalene sulfonic asidi;

(2).Onjezani madzi kuti apange α-naphthalene sulfonic acid hydrolyze, pangani β-naphthalene sulfonic acid kuchuluka;

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

(4) Kusalowerera ndale.

Tekinoloje yogwiritsira ntchitonaphthalene mkulu dzuwa kuchepetsa wothandizila madzi:

1.The mphamvu oyambirira ndi mkulu mphamvu konkire zakonzedwa.Mukasakaniza 0.5% ~ 1%naphthalene mkulu dzuwa kuchepetsa wothandiziramalinga ndi kulemera kwa simenti, madzi amatha kuchepetsedwa ndi 16% ~ 25%, ndipo mphamvu yofananira ya konkire imatha kuonjezedwa ndi 20% ~ 50% (mphamvu yoyambirira ya konkire imachulukitsidwa ndi zambiri).
2.Kukonzekera konkire yaikulu yotaya, pamenenaphthalene mkulu dzuwa kuchepetsa wothandizila madzipa mlingo wa simenti wa 0.2% ~ 0.5%, mphamvu ya konkire imakhalabe yosasinthika, imatha kuonjezera kutsika kwa konkire mpaka 10 ~ 25cm, yogwiritsidwa ntchito popangira mphamvu yokoka, kupopera konkire, ikhoza kufulumizitsa ntchito yomanga, kupititsa patsogolo ntchito yomanga.
3.ave simenti, pansi pa chikhalidwe cha kusunga mphamvu ya konkire sikuchepa, kuwonjezera pafupifupi 0.5%naphthalene njira yabwino yochepetsera madziimatha kusunga simenti pafupifupi 20%.
