The synthesis nzira yenaphthalene yakakwirira inoshanda yekudzikisa mvura mumiririri:

(1).Naphthalene yakanga iri sulfonated pakupisa kwepamusoro (160 ~ 165 ℃), kunyanya kubudisa β-naphthalene sulfonic acid, asiwo imwe shoma yeimwe naphthalene sulfonic acid;

(2). Wedzera mvura kuti uite α-naphthalene sulfonic acid hydrolyze off, ita β-naphthalene sulfonic acid content kuwedzera;

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

(4) Kusatsigira.

Iyo tekinoroji yekushandisa yenaphthalene yakakwirira inoshanda yekudzikisa mvura mumiririri:

1.Kusimba kwekutanga uye simba guru rekrete rakagadzirirwa. Pakusanganisa 0.5% ~ 1%naphthalene yakakwirira inoshanda yekudzikisa mvura mumiriririmaererano nehuremu hwesimende, mvura inogona kuderedzwa ne 16% ~ 25%, uye simba rekrete rinoenderana rinogona kuwedzerwa ne 20% ~ 50% (simba rekutanga rekrete rinowedzerwa nezvimwe).
2.Kugadzirira kwekongiri yakakura yekuyerera, apo iyonaphthalene yakakwirira inoshanda yekudzikisa mvura mumiriririye simenti dosage ye 0.2% ~ 0.5%, simba rekongiri rinoramba risingachinji, rinogona kuwedzera kudonha kwekongiri kusvika 10 ~ 25cm, inoshandiswa pagiravhiti grouting, kupomba kongiri, inogona kukurumidza kufambira mberi kwekuvaka, kuvandudza kunaka kwekuvaka.
3.ave simenti, pasi pemamiriro ekuchengetedza simba rekongiri harina kuderera, kuwedzera nezve 0.5%naphthalene inoshanda yekudzikisa mvurainogona kuchengetedza simende inenge 20%.
