Usoro njikọ nkenaphthalene ụlọ ọrụ na-ebelata mmiri dị elu:

(1).Nafthalene e sulfonated na elu okpomọkụ (160 ~ 165 ℃), tumadi na-emepụta β-naphthalene sulfonic acid, kamakwa obere ego nke ọzọ naphthalene sulfonic acid;

(2).Tinye mmiri iji mee ka α-naphthalene sulfonic acid hydrolyze gbanyụọ, mee ka ọdịnaya β-naphthalene sulfonic acid mụbaa;

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

(4) Nnọpụiche.

Teknụzụ ngwa nkenaphthalene elu arụmọrụ mmiri mbenata gị n'ụlọnga:

1.A na-akwado ike mmalite na ike dị elu.Mgbe agwakọta 0.5% ~ 1%naphthalene ụlọ ọrụ na-ebelata mmiri dị eludịka ịdị arọ nke ciment si dị, mmiri nwere ike belata site na 16% ~ 25%, na ike nke kwekọrọ ekwekọ nwere ike ịbawanye site na 20% ~ 50% (ike mbụ nke ihe na-abawanye site na ihe ọzọ).
2.The nkwadebe nke nnukwu eruba ihe, mgbenaphthalene elu arụmọrụ mmiri mbenata gị n'ụlọngamaka ciment onunu ogwu nke 0.2% ~ 0.5%, ike nke ihe na-anọgide na-agbanweghị agbanwe, nwere ike dịkwuo slump nke ihe na 10 ~ 25cm, eji maka ike ndọda grouting, pumping ihe, nwere ike mee ngwa ngwa na-ewu ọganihu, melite ewu mma.
