Abstract: When hydroxyethyl cellulose (HEC) films are treated with a solution of a hydrophobic film former such as polyvinylidene chloride copolymers or nitrocellulose in a volatile solvent to produce a heat sealable coating on the surface of the film, the adhesion between the HEC and the hydrophobic film former is improved by passing the HEC gel film through a conditioning bath containing from about 0.3 to 2.0 percent by weight (based on total bath weight) of a water soluble block copolymer of polyoxyethylene and polyoxypropylene prior to drying the film and applying hydrophobic film former solution thereto.
Abstract translation: 当用疏水性成膜剂例如聚偏二氯乙烯共聚物或硝化纤维素的溶液在挥发性溶剂中处理羟乙基纤维素（HEC）膜以在膜的表面上产生可热封的涂层时，HEC和疏水膜之间的粘附 通过使HEC凝胶膜通过包含约0.3-2.0重量％（基于总浴重量）聚氧乙烯和聚氧丙烯的水溶性嵌段共聚物的调理浴来改进前者，然后干燥膜并施加疏水性成膜剂溶液 到此。

Abstract: A unique chemical grouting composition is provided for injection stabilization of earth, sand and other porous, particulate formations or agglomerates or solids. The composition produces grouted structures of excellent strength and durability and has a wide range of uses in a system comprising sequential formulation and subsequent injection of on-site-formed aqueous solutions of (a) base materials comprising vegetative polyphenolic material derived from coniferous bark or a tannin of the catechin or condensed type and of (b) catalyst mixtures comprising a water soluble alkali metal silicate, formaldehyde or paraformaldehyde, and sufficient acid to establish the catalyst solution pH at 0.5 to 6.0 and preferably 3-5. Optional modification materials such as asphalt, clay, or a hydraulic cement, or fibrous material such as asbestos, may be included.
