BDH Sodium Naphthalene Sulfonate (Na2YOG4Tsawg dua los yog sib npaug li 18feem pua)
Kev piav qhia
BDH is a naphthalene-based highly effective water reducing agent for promoting accelerated early and ultimate strength development, commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate ), SNF, PNS and FDN etc.
Qhov zoo
Kev txhim kho loj hauv kev ua haujlwm tsis muaj dej ntau ntxiv lossis kev pheej hmoo ntawm kev sib cais. Cov txheej txheem ib txwm tsis muaj retardation, txawm tias thaum overdosed. Txhim kho qhov ntom ntom thiab nto tiav.
High water reducing rate. High strengths after 8 hours.
Tau tshaj Portland cement, Portland li qub cement, Portland Slag Cement, Flyash Cement, Portland Pozzolanic Cement, thiab lwm yam.
Txhim kho kev ua haujlwm (slump) ntawm pob zeb thaum ntxiv rau hauv kev sib xyaw tsheb.

Dosage
0.5 - 1.5 percent by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
JK-02NP can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing (better). The after-mixing approach can achieve better result.
