Yufei Tao

A hydroponic system and method for growing plants. The system comprises one or more plant support structures, one or more housing membranes, and one or more frames. The one or more plant support structures hold plant matter and have one or more holes. The one or more housing membranes are air-permeable and water-resistant, house a solution and at least a portion of the one or more plant support structures, and have one or more openings in which at least a portion of the one or more plant support structures fit into. The one or more frames support the one or more housing membranes. Methods for growing plants are also provided.

Efficient hydroponic cultivation system and method

A system for protecting temperature sensitive products. The system comprises a cover that fits over a product. The cover has a first component, a second component, and a closure system. The first component covers the top of the product and at least a portion of a first side of the product, and the second component covers at least a portion of the other sides of the product. The closure system closes openings between the first component and the second component and tightens the cover around the product. The cover is removable from the product by releasing the closure system and pulling the second component of the cover in a horizontal or downward direction away from the first side of the product.

Apparatus and method for protectively covering temperature sensitive products

A sheet comprising a plexifilamentary film-fibril network consisting essentially of high density polyethylene in an overlapping multi-directional configuration, the sheet, as-produced from a spin cell, having a normalized Frazier air permeability of between 0.002 and 0.2 m/m·minute at 50 gsm, a BET surface area of between 9 and 20 m/gm, and a normalized hydrohead of between 150 and 250 cm at 50 gsm, wherein the plexifilamentary film-fibril network in an overlapping multi-directional configuration is flash-spun from a spin fluid comprising polymer and spin agent, the spin fluid temperature being 190° C. or greater, the spin agent comprising dichloromethane, the spin fluid having a polymer concentration of 12 to 14 weight percent.

Plexifilamentary sheets

A sheet having a plexifilamentary structure with a normalized Frazier air permeability of between 0.002 and 0.2 (m/m&#xb7;minute)@50 gsm, and a normalized hydrohead of between 150 and 250 centimeters@50 gsm.

A composite laminate comprising at least one moisture vapor permeable nonwoven sheet having first and second surfaces and a fluorinated polymeric coating on the first surface of the sheet wherein (i) the fluorinated polymeric coating is present in an amount such that the total fluorine content of the coated non-woven sheet is 0.05 to no greater than 0.4 gsm, and (ii) the composite laminate, after exposure to wet timber, exhibits a retained hydrohead of at least 60 percent.

Composite comprising a nonwoven vapor permeable sheet

A flash-spun plexifilamentary fiber strand having a BET surface area of less than 12 m/g, a crush value of at least 0.9 mm/g wherein said fiber strand comprises predominantly fibers formed from polyethylene, said fibers having a total crystallinity index of less than 55%, said fiber strand having an elongation at break greater than 55% and sheets made thereof.

Flash spun plexifilamentary strands and sheets

A flash-spun plexifilamentary fiber strand having a BET surface area of less than 12 m/g, a crush value of at least 0.9 mm/g wherein said fiber strand comprises predominantly fibers formed from polyethylene, said fibers having a total crystallinity index of less than 55%, and sheets made thereof.

A composition having at least one first component containing a perfluorinated aliphatic structure in which no more than six fluorine bearing carbons are connected in any single straight chain segment, in addition a group providing binding functionality to a surface to be treated or containing at least one polymerisable double bond or containing at least one cross-linkable group, and in addition a divalent radical containing at least one group capable of forming polar interactions or hydrogen bonds, and at least one second component containing a perfluorinated aliphatic structure in which no more than six fluorine bearing carbons are connected in any single straight chain segment and a moiety containing at least one group providing binding functionality to a surface to be treated or containing at least one polymerisable double bond or containing at least one cross-linkable group.

Compositions for surface treatments

The present invention concerns a breathable product for protective mass transportation and cold chain applications, in particular a reflective sheet for covering temperature sensitive products the reflective sheet having at least a first layer made of a highly reflective moisture vapor permeable substrate having an outer side and an inner side, wherein said inner side comprises in addition at least a metal layer deposited by a PVD process to provide a thermal insulation through high reflection low convection while providing controlled moisture vapor permeability.

Breathable product for protective mass transportation and cold chain applications

A composite sheet comprises a substrate and a multi-layer coating on its outer surface, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes an olefin group and a moisture curable group, such as an isocyanate or silane group. The function of the polymeric layer includes protecting the metal layer from corrosion. A production process for the composite sheet includes depositing the precursor and exposing it to both beam radiation and moisture, which respectively promote polymerization and curing at different sites of the precursor. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation.

Method for producing metalized fibrous composite sheet with olefin coating

A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a composition capable of being polymerized and/or cross-linked by free-radical processes. After the precursor is applied, the composite sheet is exposed to beam radiation and ozone, which both promote conversion of the precursor. The function of the cured polymeric layer includes protecting the metal layer from corrosion. The use of both beam radiation and ozone promotes substantially full conversion and curing of the precursor, even in portions of the substrate that are geometrically shadowed from incident beam radiation.

A printing plate includes a substantially free gelatin free polymeric film which includes a coating layer of a polymer having at least one -POXY pendant group, pendant carboxyl groups and further comprises a sulphonated monomer, salt or derivative.

Polymeric film having a coating layer of a phosphonic acid group containing polymer

A substantially gelatin free polymeric film includes a coating layer of a polymer having at least one &mdash;POXY pendant group, pendant carboxyl group or capable of forming carboxyl groups and further comprises a sulphonated monomer, salt or derivative.

A composite film is described which consists of a primary unfilled polyester layer and a secondary polyester layer containing from 1 to 8% by weight, based on the weight of the secondary polyester layer, of finely divided silica particles having a volume weighted mean particle size diameter D&lsqb;4,3&rsqb; of from 2.3 to 6.2 micrometers. The composite film is used in backlit displays such as illuminated signboards and provides uniform light transmission while maintaining the same strength of illumination at all points over the area of the display.
