Cas No. :9004-32-4
Quantity: 10000Metric Tons Specs:CMC Price:1600 USD Metric Tons Payment Method: L/C T/T CMC (1). Relatively high water loss control capacity, especially, CMC is an efficient filtrate reducer, a little amount of which can keep the water loss control in a relatively high level, without impact on other properties of mud. (2). the mud cake formed is of high quality and great fortitude. (3). It is characterized by excellent heat and salt resistance. Under certain salinity, CMC keeps relatively good water loss control capacity and rheology behavior. The viscosity remains almost constant when CMC is dissolves in brine or water, which makes it well applied to offshore drilling and deep wells. (4) It can control the rheology behavior of the drilling fluid with good non-newtonian fluid performance (5) Besides, CMC is used as cementing fluid which prevents fluid from coming into pores and cracks and as fracturing fluid which controls the loss brought by fluid coming into wells |
