    摘要： A microparticle system for use as a retention and drainage aid in the production of alkaline and acid paper products comprises a high molecular weight flocculant polymer (6) and a silica-acid colloid blend (7), and optionally a cationic coagulant or a medium molecular weight flocculant (5). The high molecular weight flocculant polymer (6) may be added to the furnish after the fan pump (1) and prior to the pressure screen (2); the silica-acid colloid blend (7) may be added to the furnish after the pressure screen (2), and optionally, the coagulant or medium molecular weight flocculant (5) may be added prior to the fan pump (1). Addition of the microparticle system to the paper furnish improves retention and drainage during the papermaking process and sheet formation. The acid colloid of the silica-acid colloid blend (7) is a polymer or a copolymer of a melamine aldehyde acid colloid.

    摘要： A natural gum is used to provide improved emulsification of alkenyl succinic anhydride (ASA) sizing agents for paper products. The natural gum can be nonionic, cationic, anionic, amphoteric, oxidized, derivatized, or modified. The preferred natural gum is from the family of galactomannan gums in which guar gum is a primary example. The alkenyl succinic anhydride (ASA) size emulsion formed with the natural gum improves stability and the film formed is evenly distributed, thereby promoting more uniform sizing of the paper product. The ratio of the ASA to natural gum in the emulsion ranges from 0.01:1 to 100:1, and preferably 0.1:1 to 20:1. The amount of ASA size is 1 lb./ton to 10 lbs./ton of finished paper product and preferably 2 lbs./ton to 8 lbs./ton. A surfactant may be used to further improve the stability of the emulsion.

    摘要翻译： 天然胶用于改善纸制品中链烯基琥珀酸酐（ASA）施胶剂的乳化性。 天然胶可以是非离子型，阳离子型，阴离子型，两性型，氧化型，衍生型或改性型。 优选的天然树胶来自半乳甘露聚糖树胶族，其中瓜尔胶是主要例子。 用天然胶形成的链烯基琥珀酸酐（ASA）胶乳改善了稳定性，并且形成的膜均匀分布，从而促进了纸制品更均匀的上浆。 乳液中ASA与天然胶的比例范围为0.01:1至100:1，并且优选为0.1:1至20:1。 ASA尺寸的量为1磅/吨至10磅/吨成品纸产品，优选2磅/吨至8磅/吨。 表面活性剂可用于进一步改善乳液的稳定性。

    摘要： Compositions and methods for cleaning metal and non-metal surfaces utilising a nonionic surfactant and an enzyme are disclosed. A composition comprising at least one nonionic surfactant and at least one enzyme and having a pH of between 6 and 9.5 is specifically disclosed. An anionic surfactant may optionally be included in the composition. A method for cleaning a surface using this composition, and a method for cleaning a surface using a first composition comprising at least one nonionic surfactant and a second composition comprising at least one enzyme are also disclosed.
