Product Description
JKN-RT-700L can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal particles to prevent their enlarging. So it can retard hydrating of cement slurry.
Characteristics
Normal dosage: 0.2%～2.0% (BWOS), it is sensitive for temperature, should add more with increasing of temperature.
Reduce consistency of cement slurry and improve the rheology.
Retard the thickening time efficiently.
Suitable temperature: circulate temperature under bore is 110℃～140℃(BHCT).
JKN-RT-700L is composed of various compounds such as gluconate, hydroxy carboxylic acid, etc.
