The heat-conducting layer comprises the graphite layer and the first metal plating layer, and the first metal plating layer is arranged on the surface of the side, far away from the pressure-sensitive adhesive layer, of the graphite layer. Therefore, the graphite layer can effectively improve the bending resistance of the heat-conducting layer and the heat-conductive adhesive tape. Meanwhile, the metal layer is a first metal plating layer, the plating layer is arranged on the surface of the graphite layer by film plating modes such as metal evaporation and sputtering, and the graphite layer and the metal layer can be combined well by adopting an additional adhesive layer when the graphite layer and themetal layer are not stuck by the traditional adhesive tapes correspondingly, so that the heat-conducting property of the heat-conducting adhesive tape can be further improved.

Spherical green tea processing technology
ActiveCN103392844BReduce moisture contentKeep it originalPre-extraction tea treatmentShootRoom temperature
The invention relates to a spherical green tea processing technology. The technology comprises the following steps: picking one-bud one-leaf tender bud shoots in early spring and late autumn, carrying out indoor withering at a temperature of 20-22DEG C under a humidity of 65-75% RH for 7h, deactivating enzymes in a roller enzyme deactivating machine at 400DEG C for 2.5-5min, cooling to room temperature, repeating kneading and baking at 60-70DEG C for 6h, baking in a baking machine at 100DEG C for 10-11h, slowly cooling to room temperature, and packaging. The spherical green tea processing technology allows tea leaves to form stable spheres through adopting the repeated kneading and baking, so the tea leaf impression is improved; and water in the tea leaves is gradually lost step by step in the whole technological process, so the tea color is pure, and the mouthfeel is good.

Mirror-surface leather with crystal transferred and attached
InactiveCN104404779ATransparent surfaceImprove surface brightnessLamination ancillary operationsSynthetic resin layered productsTransmittanceWoven fabric
The invention relates to mirror-surface leather with crystal transferred and attached. The mirror-surface leather is manufactured with a dry-process film-transferring machining method. Ultra-fine fiber non-woven fabric is selected to serve as backing fabric, the backing fabric is coated with water-borne polyurethane resin slurry which is divided into two layers of a surface layer and a backing layer adhesion layer respectively, then leather base cloth is attached, paper and leather are separated, the crystal is attached, and finally leather slurry is attached; the temperature of an oven is controlled to range from 120 DEG C to 130 DEG C during first coating, a doubling roller for transfer and attachment of the crystal is controlled to be at a normal temperature, and the flow of water is synchronous with the rotation speed of the doubling roller. The produced crystal mirror-surface leather does not have air bubbles or needle holes, is high in transmittance and good in brightness, has a flat and smooth surface and can be suitable for multiple fields such as sofa, automotive trims, office accommodations, furniture and walls.

Finishing process for glued interweaved fabric
ActiveCN107034680ASmooth silk surfaceNo creaseLiquid/gas/vapor open-width material treatmentLiquid/gas/vapor removal by suctionPulp and paper industryMoisture
The invention relates to a finishing process for a glued interweaved fabric and belongs to the technical field of viscose treatment. The finishing process is characterized by comprising the following process steps of: 1) feeding a gray fabric of the fabric into a jig dyeing machine in an open width manner, and operating the fabric in water at 13-18 DEG C till the fabric is flat without folding edges and creases; 2) rolling dyed wet cloth down to an A type rack, and keeping the wet cloth roll to rotate uniformly at a rotating speed of 18-22r / min; 3) after unrolling the wet cloth on the type A rack, absorbing water through a water absorption pipe in front of a rolling groove to control the moisture content of the fabric at 53-60%; and 4) controlling the liquid rate of the fabric after water absorption at 65-70%, preparing a flexible finishing liquid in the rolling groove, and then performing a flexible treatment and drying step. According to the process provided by the invention, the quality of the product is obviously enhanced, consumption of steam and power is saved, and the dosage of an auxiliary agent is greatly reduced.
