在室内试验研制出了一种无铬木质素磺酸盐稀释剂(XD)。这种稀释剂在较宽的温度范围内具有优良的稀释性能,其抗温能力和稀释效果都比铁铬木质素磺酸盐(FCLS)好。XD无环境污染,有降失水作用。本文探讨了XD在泥浆中的作用机理。
A chromium-free lignosulfonate thinner (XD) has been developed in laboratory tests. This diluent has excellent dilution properties over a wide temperature range, and has better resistance to temperature and dilution than iron chromium lignosulfonate (FCLS). XD no environmental pollution, loss of water loss role. This paper explores the mechanism of action of XD in mud.
