Synthesis txoj kev ntawmnaphthalene High EfficiCiency Dej Reducing Tus Neeg Sawv Cev:

(1).Naphthalene tau sulfonated ntawm qhov kub (160 ~ 165 ℃), feem ntau yog ua rau tus neeg sulfonic acid, tab sis kuj yog lwm tus naphhalene sulfonic acid;

(2). Ntxiv cov dej kom ua α-naphystalene sulfonic acid hydrolyze tawm, ua β-naphystal sulfonic acid cov ntsiab lus nce;

(3). β-naphystalene sulfonic acid thiab formaldehyde condensation;

(4) nruab nrab.

Daim ntawv thov tshuab ntawmNaphthalene High EfficiCic Dej Reducing Tus Neeg Sawv Cev:

1.Qhov lub zog thaum ntxov thiab muaj zog muaj zog yog npaj tau. Thaum sib xyaw 0.5% ~ 1%naphthalene High EfficiCiency Dej Reducing Tus Neeg Sawv CevRaws li qhov hnyav ntawm cov xis mas yuav raug txo los ntawm 16% ~ 25%, thiab cov pob zeb sib luag tau nce los ntawm kev nce qib nce ntxiv).
2.Qhov kev npaj ntawm cov ntws loj loj, thaum lubNaphthalene High EfficiCic Dej Reducing Tus Neeg Sawv CevRau cov cement noj ntawm 0.2% ~ 0.5%, lub zog ntawm cov pob zeb ntawm cov kev tsim kho, tuaj yeem ceev cov kev tsim kho kev tsim kho, txhim kho cov kev tsim kho.
3.eave xis mas, raws li kev tswj hwm lub zog ntawm cov pob zeb ua tsis tsis kam, ntxiv txog 0.5%naphthalene Cov dej ntws tsawgtuaj yeem txuag cov cement txog 20%.
