| 20090133847 | PROCESS OF USING SODIUM SILICATE TO CREATE FIRE RETARDANT PRODUCTS - Wood products, specifically wood commonly used in construction including dimension lumber, pressure treated pine, composite wood materials such as plywood, particle board, and wafer board, and samples of paper and fabric were variously treated with concentrations of sodium silicate (Na | 05-28-2009 |
| 20120193054 | METHOD AND APPARATUS FOR FORMING A FIBROUS MEDIA - Methods and apparatuses for forming a nonwoven web are described herein. The apparatus includes a mixing partition defining one or more openings therein that permit fluid communication between two fluid flow streams, at least one of which includes a fiber. The apparatus also includes an enclosed region surrounding at least a portion of the mixing partition. The enclosed region is adapted to provide an applied pressure to a fluid flow stream to urge the stream through one or more of the openings in the mixing partition. The apparatus also includes a receiving region designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream. | 08-02-2012 |
| 20120199303 | Partially Fire Resistant Insulation Material Comprising Unrefined Virgin Pulp Fibers and Wood Ash Fire Retardant Component - A partially fire resistant cellulosic fiber thermal insulation material from a fibrous web of unrefined virgin softwood and hardwood provides fibers which provides an R-value (as measured by the ASTM C518 test) of at least about 3, and a wood ash fire retardant component present in and/or on the fibrous web in an amount of at least about 1.5% by weight of the fibrous web and sufficient to impart at least partial fire resistance (as measured by the ASTM E970-08A test) to the fibrous web. Also, a process for preparing this at least partially fire resistant thermal insulation material. | 08-09-2012 |
| 20120255695 | Addition of Endothermic Fire Retardants to Provide Near Neutral pH Pulp Fiber webs - A process in which an at least partially delignified pulp fiber web having a Kappa number of less than about 130 is treated with an aqueous endothermic fire retardant solution having a pH of about 10 or less. The treated pulp fiber web has a near neutral pH of from about 5 to about 9, and is treated with at least about 20 lbs of endothermic fire retardants per ton of the pulp fiber web, with at least about 5% of the total amount of endothermic fire retardants being added at a point prior to when the pulp fiber web is formed. Also a fire resistant pulp fiber web having a near neutral pH. | 10-11-2012 |
| 20130133850 | FIRE RETARDANT TREATED FLUFF PULP WEB AND PROCESS FOR MAKING SAME - A fire resistant fluff pulp web made from a fluff pulp web, a fire retardant component present in and/or on the fluff pulp, and a fire retardant distributing surfactant which distributes the fire retardant component in and/or on the fluff pulp web in a manner so that the fluff pulp web passes one or more fire resistance tests. Also, a process for preparing these fire resistant fluff pulp webs, as well as for treating outer fibrous layers comprising an air-laid mixture of these fire resistant fluff pulp fibers and bicomponent fibers with up to about 5% additional fire retardant and which are used in fire resistant air-laid fibrous structures useful in upholstery, cushions, mattress ticking, panel fabric, padding, bedding, insulation, materials for parts in devices and appliances, etc. | 05-30-2013 |
| 20130264020 | ADDITION OF ENDOTHERMIC FIRE RETARDANTS TO PROVIDE NEAR NEUTRAL pH PULP FIBER WEBS - A process in which an at least partially delignified pulp fiber web having a Kappa number of less than about 130 is treated with an aqueous endothermic fire retardant solution having a pH of about 10 or less. The treated pulp fiber web has a near neutral pH of from about 5 to about 9, and is treated with at least about 20 lbs of endothermic fire retardants per ton of the pulp fiber web, with at least about 5% of the total amount of endothermic fire retardants being added at a point prior to when the pulp fiber web is formed. Also a fire resistant pulp fiber web having a near neutral pH. | 10-10-2013 |
| 20130292077 | METHOD FOR FORMING A FIRE RESISTANT CELLULOSE PRODUCT, AND ASSOCIATED APPARATUS - A method is provided for forming a fire resistant cellulose product. A fire-retarding solution and a bonding agent are combined with refined cellulose fibers to form a fiber mixture, and the fire-retarding solution and bonding agent are substantially uniformly distributed with respect to the cellulose fibers within the fiber mixture. The fiber mixture is exposed to an actuating element, wherein the actuating element is configured to actuate the bonding agent so as to facilitate cohesion of the cellulose fibers and form the fiber mixture into a fiber board member, the fiber board member having opposing major surfaces. A cellulose sheet member is engaged with each major surface of the fiber board member, such that each cellulose sheet member substantially covers the respective major surface. An associated apparatus is also provided. | 11-07-2013 |
| 20130319626 | Method and Material for Manufacturing Backplane Component - The present invention provides a method and material for manufacturing backplane component. The method includes (1) providing a raw material, which comprises one or more of paper, bamboo, and wood; (2) pulverizing the raw material to form slurry; (3) adding functional agents in the slurry, wherein the functional agents comprise one or more of water repellent agent for waterproofing, flame retardant agent for flame retardation, solidification agent for speeding up solidification, plastics for improving stiffness, glass fibers for improving strength, metal powder for enhancing heat dissipation, and reflection assisting agent for improving reflection capability; (4) applying a mold in a forming machine to carry out suction forming of the slurry; and (5) drying and shape-fixing so as to make a backplane component. | 12-05-2013 |
| 20140174681 | FIRE RETARDANT TREATED FLUFF PULP WEB AND PROCESS FOR MAKING SAME - A fire resistant fluff pulp web made from a fluff pulp web, a fire retardant component present in and/or on the fluff pulp, and a fire retardant distributing surfactant which distributes the fire retardant component in and/or on the fluff pulp web in a manner so that the fluff pulp web passes one or more fire resistance tests. Also, a process for preparing these fire resistant fluff pulp webs, as well as for treating outer fibrous layers comprising an air-laid mixture of these fire resistant fluff pulp fibers and bicomponent fibers with up to about 5% additional fire retardant and which are used in fire resistant air-laid fibrous structures useful in upholstery, cushions, mattress ticking, panel fabric, padding, bedding, insulation, materials for parts in devices and appliances, etc. | 06-26-2014 |
