The four-wheeler change direction already at from abroad usher in of engineering vehicle top get actual application, such as the United States CMI Terex of four track cement the stand spread the machine SF-3004 and the United States Case company of 560 dig ditch machine etc..

四轮转向已在从国外引进的工程车辆上得到实际应用，如美国CMI Terex的四履带水泥摊铺机SF-3004和美国Case公司的560挖沟机等。

TH-904 is used as chelant in papermaking coating, building coating, concrete retarder, water reducer, woven and dyeing. Its performance can reach to that of SN-5040. Adding TH-904 to slurry during grinding process of bolus alba, lime carbonate, pottery clay, titanium pigment, French chalk, barium sulfate, coal-water slurry, etc., the viscosity can be largely reduced and the dispersed slurry is stable.

TH-904水性分散剂广泛用做造纸涂料及建筑涂料的分散剂、混凝土缓凝剂、减水剂以及纺织印染等行业作螯合分散剂，性能达到SN-5040水平，在高岭土、碳酸钙、陶土、钛白粉、滑石粉、硫酸钡、水煤浆及水泥等浆料的研磨加工过程中加入TH-904分散剂能极大地降低被加工物料的粘度，便于物料的加工，且分散后浆料粘度稳定。

Aiming to the problem of the brittle fracture of cement sheath caused by perforation and other production enhancing measures after well cementing of thin oil reservoir wells,latex,rubber powders and PVA fibers were studied to reduce cement stone friability and distinguish the toughness and elasticity of cement stone accurately.

针对国内油田薄油层井、小间隙井和侧钻井固井后射孔及后续增产措施造成的水泥环脆裂问题，为了降低水泥石的脆性，正确评价不同材料对水泥石韧性或弹性的影响，对掺有胶乳、橡胶粉和PVA纤维水泥石的抗折强度、抗压强度、抗冲击功和弹性模量等力学性能进行了研究，并对3种材料的作用机理进行了剖析。

The removal of MMVF cement is likely to generate less atmospheric dust than the removal of the more friable insulating board and insulating compound.
