摘要:
A coated paperboard is disclosed which includes a barrier coating containing substantially no fluorochemical or wax, exhibiting good resistance to oil and grease, no tendency toward blocking, the coated paperboard being fully repulpable as well as compostable. The coated paperboard may further have a printable coating on a surface opposite from the barrier coating.
摘要:
This invention relates to a folded core structure made from paper comprising 20-85 weight percent of carbon fiber floc. The carbon fibers have a non-circular cross sectional aspect ratio of at least 1.5:1. The paper has a fiber volume fraction of at least 35%. The arithmetic mean length of the carbon fibers is at least 0.5 mm. and length weighted mean length at least 0.9 mm.
摘要:
The invention relates to a resin impregnated paper substrate with crystalline triazine, preferable vapor deposited triazine. The crystalline triazine preferably is present in an amount of about 5 g/m2 or higher and about 100 g/m2 or lower. The invention further relates to a process for making a laminate comprising at least one cured layer of amine-formaldehyde resin and a paper, wherein a resin impregnated paper with vapor deposited triazine is submitted with one or more other layers to pressure and/or sufficient temperature to cure the resin and at least part of the triazine.

摘要:
Provided is a thermosetting resin decorative plate comprising a decorative sheet comprising a base material and a picture layer formed thereon, wherein the base material is a nonwoven fabric comprising chemical fibers or a mixed paper of chemical fibers and pulps, and the above decorative plate makes it possible to work a three-dimensional form.
摘要:
A high pressure laminate is made of several layers of paper, including from bottom to top core sheets, a decor sheet and an overlay sheet. The core sheets are either composed of cellulose fibers or composed of 30 to 90 weight percent cellulose acetate fibers and 70 to 10 weight percent cellulose fibers. The core sheets are respectively coated with either a lamination polymer or a plasticizer. The decor sheet is composed of a mixture and a conventional amount of paper making dye. The mixture comprises 30 to about 90 weight percent cellulose acetate fibers, 10 to 70 weight percent cellulose fibers and 0 to 20 weight percent fillers. The decor sheet is coated with a plasticizer. The overlay sheet is composed of cellulose fibers and is coated with a lamination polymer. Upon application of heat and pressure to the several layers a laminate is formed having thermoplastic properties, improved postformability and a significant reduction in the release of volatile organics during formation.
摘要:
A plurality of webs drawn from respective supply rolls forms a core stack which is passed through a single-level press to press boards from the press stack formed by applying cover foils to the core band. Once the pressed board forming part of the band is advanced from the press, the pressed board can be cut and trimmed from the band. The apparatus has a separating web insertion station for selectively inserting a separating web between core forming layers as part of the band so that, when one or more separating layers are inserted, each press cycle simultaneously forms two boards, but when no separating layer is inserted, only a single board is formed at each press cycle and separating operation.
摘要:
A translucent and variegated resin impregnated decorative paper laminate having the visual three-dimensional effect of depth and to a method of manufacturing the same which comprises laminating a plurality of highly absorbent, transparent paper sheets impregnated with a resin under heat and pressure sufficient to form a unified and stratified laminate.
摘要:
Drying oils are used to improve strength and durability characteristics of gypsum wallboard paper with many unexpected additional advantages. Applied before board manufacture, critical porosity characteristics are left uninterrupted. Applied after board manufacture, shear strengths are obtained beyond expectations.
