Embodiment Construction

[0019] The present invention is further described below: the manufacturing process of the disposable cup cover, which is characterized in that: the specific steps of the process are raw material beating-batching-molding-molding-hot-pressing-trimming and punching-pressing the inverted hook groove, wherein ,

[0020] 1. Raw material beating: the raw material used is mainly bagasse paddle board supplemented with a small amount of wood pulp and bamboo pulp, and is beaten with water by a beater, with a beating concentration of 4-6%;

[0021] 2. Ingredients: add water to the thick slurry prepared in step 1 until the paper fiber concentration is 0.5-1%, then add waterproofing agent and wet strength agent to increase product strength, the amount of waterproofing agent added is the mass of paper fiber 3-5%.

[0022] 3. Compression molding: After batching, press the mold directly to form a wet billet with a moisture content of 70%±5%;

[0023] 4. Hot pressing and shaping: transfer the...

Abstract

The invention provides a manufacture process of disposable bowl cover with high strength, strong stability and good water proof performance. The process includes the concrete steps of raw material beating-batching-compression molding-side shearing and punching-making back-off slot by pressing; wherein the material beating includes that: the used raw material is mainly bagasse paddle board accounting for 80-90% of total mass and supported by a small amount of wood pulp and bamboo pulp accounting for 10-20%, water dissociation beating is carried out by a beating engine, and the beating concentration is 4-6%; the compression molding includes: wet blank with water content of 65-75% is directly transferred into an aluminium or steel compression molding mold for high temperature high pressure dehydration, so that the water content of product can reach 5-7%, and the pressure thereof is 15-20x10<3>kgf, the temperature is 150+ / -10 DEG C, and the compression time is 45+ / -5 seconds. Compared withthe existing molded pulp process, the invention saves energy consumption; and the water proof performance, the strength and the stability of the product are greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of disposable daily necessities, in particular to a manufacturing process of a disposable cup cover and a cup cover produced by the process. Background technique: [0002] Disposable cups and cup lids currently on the market are usually: 1. Made of plastics such as PP, PS, PVC, etc. As we all know, cup lids made of these plastics will pollute the environment when they are recycled and disposed of, and are environmentally friendly. It is poor, and it is difficult to ensure compliance with hygienic standards; 2. The plate-shaped body is made of paper material, and then glued into a cup shape by adhesive, but because the strength of the cup body is not enough, and the cup cover itself cannot be as simple as the cup Forming, so paper cups are rarely matched with paper cup lids. [0003] In recent years, in order to solve the above problems, people in the industry have developed a pulp molding three-dimensional...
