The present invention relates to a method for manufacturing a resin-impregnated decorative paper, which method comprises the following steps: i) providing a paper, ii) impregnating the paper obtained in step i) with a first, actinic radiation-curable resin, iii) subjecting the paper obtained after step ii) to a drying step, iv) applying a second, actinic radiation-curable resin to the dried paper obtained after step iii), and v) curing the paper obtained after step iv) to obtain the resin-impregnated decorative paper.
摘要:
A coated paper or board product and a method of manufacturing the same. The product comprises a base layer made of paper or board, with at least one coating layer containing at least one polysaccharide-based pigment, and at least one polymer layer being spread on top of it. The invention can considerably improve the adhesion of the coating and the polymer layer.
摘要:
A machine for producing and treating a web of material including a material web forming device, a dewatering and drying section, at least one application apparatus, a drying device and a processing device. The material web forming device forms a material web continuously from a supplied fibrous suspension. The dewatering and drying section is arranged along a material web path after the material web forming device. The section extracts water from the web by way of at least one of thermal and mechanical action. The at least one application apparatus is arranged along the material web path after the dewatering and drying section. The apparatus applies liquid or pasty application medium to at least one side of the web. The drying device is arranged along the material web path after the application apparatus. The drying device dries the moving material web to a final drying state. The processing device is arranged along the material web path after the drying device. The processing device at least one of processing, picking up and discharging the web. The at least one application apparatus includes at least one contactless application unit discharging application medium in a free application medium jet, an application medium curtain, an application medium veil or an application medium droplet spray. The at least one contactless application unit applying the application medium to the web on the basis of forces to the application medium, movement impulses imparted to the application medium and on movement of the application medium induced by the force of gravity.
摘要:
A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a different substance. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel.
摘要:
The invention relates to a substrate coated with an oriented multilayer polymeric film comprising at least two layers of polymer particles oriented along two different directions with respect to one another. Such an oriented multilayer polymeric film has improved flexibility as well as improved gas barrier properties. A method of forming the film on a substrate is also disclosed.
摘要:
The present invention relates to a method of applying treatment chemicals to a dry, creped tissue material, said method comprising the steps of: a) applying a first treatment composition containing at least one treatment chemical to the dry, creped tissue material to produce a first layer having at least one first treatment chemical, and b) applying at least one further treatment composition containing at least one other treatment chemical to produce at least one other layer on the first layer, said other layer having at least one other treatment chemical, and a tissue material or tissue product obtainable according to this method. The process of the invention enables the production of tissue products, wherein the treatment chemicals are optimally distributed, depending on their purpose of use, and can develop their properties.
摘要:
A cleaning sheet with a tacky surface coating is used to clean feed rollers in copying machines or similar equipment and similarly-coated cloths are used for the removal of particles from other surfaces to be cleaned. The cleaning articles are made by printing the tacky material on sheet material such as paper or cloth. Relatively thick layers of tacky material are applied quickly and economically by the use of a multi-stage printing press which builds up a thick layer from a plurality of thin layers.
摘要:
The invention concerns a method for two-sided coating of a printing-paper web with a coating paste or equivalent. In the method, the paper web is passed through the coating part of the paper machine, in which the first side of the web is coated in the first coating station of said coating part, and the coating-agent layer produced on the face of the web is dried at least partly by means of a first drying unit. The second side of the web is coated in the second coating station of the coating part, and the second coating-agent layer produced on the face of the web is dried at least partly by means of a second drying unit. The coating-agent layers are formed onto the paper web alternatively by spreading the necessary amount of coating agent by means of a coating device as a film onto the face of a film press roll, from which the coating agent is transferred in the nip between the film press roll and the back-up roll as a coating-agent layer onto the paper web, or by forming the coating-agent layer directly onto the paper web by means of a blade coating device that coats the web face while using one of the film press rolls as the back-up rolls of the blade coating devices.
