摘要： A method of determining a quantity of amorphous SiC2-containing impurities in a montmorillonite clay sample comprising the steps of: (a) analyzing the clay sample to determine the weight percent of SiO2 contained in the clay sample; (b) analyzing the clay sample for non-montmorillonite SiO2-containing crystalline components; (c) calculating the weight percent of SiO2 from step (a) that is derived from the montmorillonite and amorphous SiQ2-containing impurities by lowering the weight percent of SiO2 in step (a) based on the non-montmorillonite SiO2-containing crystalline impurities found in step (b); and (d) determining the amorphous SiO2-containing impurity portion of the SiO2 calculated in step (c) by further lowering the amount of SiO2 from step (c) until the amount of montmorillonite-derived SiO2 is consistent with one or more properties of the clay sample, the amount of further lowering being proportional to an amount of amorphous SiO2-containing impurities contained in the clay sample.

摘要： A clay purification process, for removing impurities recovered with the clay, particularly a montmorillonite clay, includes the steps of separating the clay from rocks and other large non-clay impurities; dispersing the clay and smaller impurities in water, preferably at a concentration of at least about 4% by weight clay, based on the total weight of clay and water, more preferably about 6-10% by weight clay in water, to provide a clay slurry; passing the clay slurry through a series of hydrocyclones to remove the larger particles (impurities) while retaining clay particles having a size of about 100 microns or less, particularly about 80 microns or less; ion exchanging the clay to remove at least about 95% of the interlayer, multivalent (e.g., divalent and trivalent) cations in an ion exchange column, wherein the multivalent ions are replaced by monovalent cations, such as sodium, lithium and/or hydrogen; and then centrifuging the clay to remove a majority of the particles having a size in the range of about 0.5 .mu.m to about 100 .mu.m.

摘要： An improved method of manufacturing geosynthetic clay liners is provided. The method of manufacture enables the construction of a structurally sound liner without the use of glue or adhesive and further without the use of needle punching or quilting. The method of manufacture also eliminates the need for any subsequent drying step. Water in combination with compression is used to adhere the granular bentonite layer to the inside surfaces of the cover sheet and the primary carrier sheet and further to provide structural stability to the bentonite layer itself.

摘要： A geosynthetic clay liner is disclosed for providing barriers in landfills that substantially preclude the migration of liquids. The geosynthetic clay liner includes a layer of bentonite disposed between a primary carrier sheet and a cover sheet. The primary carrier sheet and the cover sheet are linked via plurality of tufting threads. A bight or loop portion of the tufting thread extends through to the undersurface of the lower or primary carrier sheet and is partially melted to prevent the bight portion from slipping back through the primary carrier sheet. The partially melted bight portions create an under surface with a high coefficient of friction thereby enabling the geosynthetic clay liner to be installed on steep slopes or banks of landfills or ponds.

摘要： A clay liner is provided for use in constructing low permeability barriers in the bottom of landfills and man-made bodies of water. The liner is provided in the form of a layer of bentonite preferably disposed between a primary carrier sheet and a cover sheet. At least one outer edge of either the cover sheet or the primary carrier sheet is made from a material that allows substantial bentonite migration through or includes a slit that enables bentonite to migrate through while the remaining areas of the cover sheet or primary carrier sheet are fabricated from a fabric that does not permit substantial bentonite migration. When two liners are disposed adjacent to each other in the bottom of the landfill or pond, the two liners are overlapped so that the more open portion of one liner engages the adjacent liner. Upon activation, the bentonite migrates through the more open fabric to create a seal between the two adjacent liners. The result is a self-sealing geosynthetic clay liner system.
摘要翻译：提供粘土衬垫，用于在垃圾填埋场底部和人造水体中建造低渗透性屏障。衬垫以膨润土层的形式提供，优选地设置在主承载片和覆盖片之间。覆盖片或主承载片的至少一个外边缘由允许大量膨润土迁移通过或包括使得膨润土迁移通过的狭缝的材料制成，而覆盖片或初级载体片的其余区域被制造从不允许大量膨润土迁移的织物。当两个衬垫在垃圾填埋场或池塘的底部彼此相邻地布置时，两个衬垫重叠，使得一个衬套的较开的部分接合相邻的衬垫。活化后，膨润土通过更开放的织物迁移，在两个相邻衬垫之间形成密封。结果是自密封土工合成粘土衬垫系统。

摘要： A friction enhancing material is applied to at least one surface of the geosynthetic clay liner. The placement of friction enhancing material on the surface of the liner that engages a slope or embankment of a landfill helps the liner maintain its position during and after installation. The improved frictional contact between the liner and the slope or embankment permits use of bentonite liners on steeper slopes or embankments and therefore enables more efficient construction of landfills. The friction enhancement material may also be applied to the surface to improve contact between the upper surface of the geosynthetic clay liner and the cover soil. The friction enhancement material may be high density polyethylene, EVA, rubbers and other polymeric materials.
