    • An improved stop-leak formulation containing ground plant root material, glycol, and water is provided. The formulation can contain other additives such as corrosion inhibitors, lubricating agents, and the like. The stop-leak formulations exhibit significantly improved storage stability. Over extended storage periods, the plant root powder remains readily dispersible in the glycol/water mixture. Generally the stop-leak formulations contain 1 to 50 parts by weight plant root powder, 20 to 80 parts by weight glycol, and 100 parts by weight water. One preferred stop-leak formulation contains 15 to 30 parts by weight ginger root powder, 35 to 55 parts by weight diethylene glycol, and 100 parts by weight water.
    • 提供了含有地面植物根材料,乙二醇和水的改进的止漏剂。 制剂可以含有其它添加剂,例如腐蚀抑制剂,润滑剂等。 停止泄漏配方表现出显着改善的储存稳定性。 在延长的储存期间,植物根粉末容易分散在二醇/水混合物中。 一般来说,止漏剂含有1至50重量份的植物根粉,20至80重量份的二醇和100重量份的水。 一种优选的止漏剂包含15至30重量份姜根粉末,35至55重量份二甘醇和100重量份水。
