紙餐盒可用于餐廳、食堂、街頭小吃、美食包裝午餐盒、水果蔬菜盒及酒店商務用品等,使用非常方便,可高度降解,不會破壞環(huán)境。紙餐盒設計美觀大方,既避免了資源的浪費,又變廢為寶,避免了處理工作過程中的環(huán)境造成污染。下面,具體來說下,一次性紙餐盒生產制作工藝流程。
Paper lunch boxes can be used in restaurants, canteens, street snacks, food packaging lunch boxes, fruit and vegetable boxes, and hotel business supplies. They are very convenient to use, highly biodegradable, and will not damage the environment. The design of the paper lunch box is beautiful and generous, which not only avoids resource waste but also turns waste into treasure, avoiding environmental pollution during the processing process. Below, specifically, the production process of disposable paper lunch boxes.
1、制漿流程。
1. Pulping process.
紙餐盒的主要原料一般為漂白木漿,通常生產較多的商品級產品需要選擇進口木漿。中級產品可以選擇國內普通木材,紙漿、低檔產品可選用蔗渣漿、草漿、竹漿、蘆葦漿和白紙邊等短纖維漿。這里,氣泡漿料和水輪機碎漿機作用。
The main raw material for paper lunch boxes is usually bleached wood pulp, and it is usually necessary to choose imported wood pulp to produce more commodity grade products. Intermediate products can choose domestic ordinary wood, while pulp and low-end products can choose short fiber pulp such as bagasse pulp, straw pulp, bamboo pulp, reed pulp, and white paper edge. Here, the action of the bubble slurry and the hydraulic turbine slurry crusher.
通過切絲對纖維進行皂化處理,提高纖維的結合能力,并添加相關輔料,提高紙漿餐具的防潮性能和成品的防水性能,還可以添加特定的相關材料。鋪料配漿后,調節(jié)原漿濃度,使其可以達到2%左右,以利原漿在網模上脫水成型。
Saponification treatment of fiber through cutting can improve the binding capacity of fiber, and add relevant auxiliary materials to improve the moisture-proof performance of pulp tableware and the waterproof performance of finished products, and specific relevant materials can also be added. After paving and slurry preparation, adjust the concentration of raw slurry to about 2%, so as to facilitate dewatering and molding of raw slurry on the mesh mold.
2、成型流程。
2. Forming process.
成型技術就是將原漿制成,具有一定不同形狀的半濕態(tài)紙漿餐具的毛坯。也就是經制漿工序設計出來的紙漿,在金屬材料模具上,脫水過程中形成濕紙漿餐具底層,這是紙制餐具生產過程中的關鍵工序,紙漿中95%左右的水分在形成過程中被去除。
Forming technology is the process of making semi-finished pulp tableware with different shapes from raw pulp. That is, the pulp designed through the pulping process forms the bottom layer of wet pulp tableware on the metal material mold during the dehydration process, which is a key process in the production of paper tableware. About 95% of the water in the pulp is removed during the formation process.
因此,這一過程的產品質量、能耗都很高消耗、生產效率的提高和破碎率起著決定性的作用。成型質量取決于成型機、成型方式、模具結構以及原漿質量和質量因素。
Therefore, the product quality and energy consumption of this process are high, and the improvement of production efficiency and crushing rate play a decisive role. The molding quality depends on the molding machine, molding method, mold structure, as well as the quality of the raw material and quality factors.

3、模壓與烘干。
3. Moulding and drying.
通過專用成型機成型,去除成型過程中紙漿餐具雛形中未去除的水分,降低干燥脫水成本的過程稱為成型。同時模壓可提高以及纖維間的結合力并增加濕紙模的強度。干燥是用紙漿和餐具的純銅模具對紙漿和餐具的原型進行加熱和蒸發(fā),并在成型后除去剩余的水分,還具有殺菌功能。對整個干燥過程進行合理的設計,以節(jié)約成本,已成為提高制漿餐具企業(yè)經濟效益的主要途徑。
The process of forming by using a dedicated molding machine to remove any water that has not been removed from the pulp tableware prototype during the molding process and reduce the cost of drying and dehydration is called forming. Simultaneously molding can improve the adhesion between fibers and increase the strength of wet paper molds. Drying involves heating and evaporating the prototype of pulp and tableware using pure copper molds of pulp and tableware, and removing any remaining moisture after molding. It also has a bactericidal function. Reasonable design of the entire drying process to save costs has become the main way to improve the economic benefits of pulp and tableware enterprises.
4、整型與切邊。
4. Integer and trimming.
該工藝采用熱模壓制成型,壓延,消除紙張網格成型時留下的網痕,使內外表面光滑,并根據(jù)不同客戶的使用要求對一定的壓力,還有文字和圖案。同時切掉餐具邊緣的毛刺,壓下便于一次性飯盒蓋折疊的壓痕打開。
This process adopts hot mold pressing and rolling to eliminate the mesh marks left by paper mesh forming, making the inner and outer surfaces smooth. It also applies certain pressure according to different customer requirements, as well as text and patterns. At the same time, cut off the burrs on the edges of the tableware and press down to open the indentation that facilitates the folding of the disposable lunch box cover.
紙餐盒使用方便,成本低廉,已廣泛運用于餐飲行業(yè)中。由于采用紙材料制作,因而既可以回收使用,又可以通過掩埋或燃燒等方式處理,而不致于造成嚴重的環(huán)境污染,具有較高的環(huán)保價值。您有需求就來我們網站http://www.ear898.com咨詢吧!
