防漏堵漏材料一直备受关注.室内用优选的十二烷基硫酸钠、十二烷基苯磺酸钠和水、羟乙基淀粉、聚丙烯酰胺以及专有化学处理剂为原料,研发出新型防漏堵漏工作液.实验和应用表明,新型工作液能够封堵大小不同的漏失通道且不影响正常作业.经1000～2000倍显微观察,工作液中有一种球形材料,静态下具有“一核二层三膜”微观结构.内部似气囊,外部似绒毛,遂称该材料为“绒囊”.静态下,气囊绒毛结合完整,凝胶强度高;动态下,绒毛被剪切或散落,黏度低,满足工程需要.若漏失通道直径或宽度大于绒囊直径,绒囊堆积成侧躺圆锥状分解工作液液柱压力,实现防漏堵漏;漏失通道直径或宽度与绒囊直径相当,绒囊被低压区吸入时由圆形变成椭圆形,增加漏入漏失通道阻力,实现防漏堵漏;漏失通道直径或宽度小于绒囊直径,绒囊工作液利用高凝胶强度形成非渗透膜屏蔽漏失通道,实现防漏堵漏.从而,全面封堵大小不一的漏失通道。
Leak-proof plugging material has been of great concern indoors with the preferred sodium lauryl sulfate, sodium dodecyl benzene sulfonate and water, hydroxyethyl starch, polyacrylamide and proprietary chemical treatment agent as raw materials, research and development A new type of leak-proof plugging solution.Experiments and applications show that the new type of working fluid can plug the different size of the leak channel and does not affect the normal operation.After 1000 to 2000 times the microscopic observation, the working fluid has a spherical material, static With “a core of two layers and three membranes” microstructure. Like internal airbags, external like hair, then called the material for the “cashmere bag.” Static, airbag villus combined integrity, high gel strength; dynamic, Fluff is cut or scattered, the viscosity is low, to meet the needs of the project.If the diameter or width of the lost channel is larger than the diameter of the velvet pouch, the velvet pockets accumulate into a cone-shaped liquid column pressure to disintegrate the working fluid to achieve leakproof plugging; The width is equivalent to the diameter of the velvet pouch, the velvet pouch is changed from circular to oval when it is inhaled by the low-pressure area, which increases the resistance of the leak-through channel and achieves the leak-proof plugging; the diameter or width of the lost channel is smaller than the diameter of the velvet bag; High gel strength forms impermeable membrane barrier leakage Road to achieve leak-proof sealing. Thus, the overall dropout channel block sizes.
