鋁塑板剝離強度的怎么生產出來的?

鋁塑復合板的生產在外行人看來非常簡單,但實際上它是一種技術含量高的新產品,因而鋁塑板產品的質量控制上就有一定技術難度。這一期講座主要談一談影響鋁塑復合板180°剝離強度的因素。
The production of aluminum plastic composite board is very simple, but in fact it is a kind of new product with high technical content, so it is difficult to control the quality of the aluminum plastic plate. This lecture mainly talks about the factors affecting the 180 degree peel strength of aluminum plastic composite panels.
鋁箔本身質量問題。這雖然是一個比較隱蔽的問題,但已經在鋁塑板的質量中體現出來。一方面是鋁材的熱處理工藝問題,另一方面有的鋁板和生產者在使用回收的廢鋁時質量控制不嚴。這就要求鋁塑板的生產者在對材料生產者進行各方面的評價,確定合格分承包方后建立業務往來以確保材料質量。
The quality of aluminum foil itself. Although this is a relatively hidden problem, it has been reflected in the quality of aluminum plastic panels. On the one hand, the heat treatment process of aluminum, on the other hand, some aluminum plates and producers in the use of recycled aluminum waste quality control is not strict. This requires aluminium-plastic sheet producers to conduct various aspects of the evaluation of the material producers, determine qualified sub-contractors to establish business contacts to ensure the quality of materials.
鋁板的前處理問題。鋁板的清洗與化層質量直接關系到鋁塑板的復合質量。鋁板首先要經過清洗除去表面油污雜質等,使表面形成一層致密的化學層,以便于高分子膜產生很好的粘結。但有的廠家在前處理過程中對處理液的溫度、濃度、處理時間、處理液的更新等控制不嚴,影響清洗質量。更有甚者個別新生產廠家對鋁板不進行任何前處理而直接使用。所有這些必將導致復合質量差、180°剝離強度偏低或不穩定。

The problem of pretreatment of aluminum plate. The quality of aluminum sheet cleaning is directly related to the quality of aluminum plastic panels. Aluminum plate should first be cleaned to remove oil and impurities, so that the surface of a dense layer of chemical, in order to facilitate the formation of a good bonding polymer film. However, some manufacturers in the pretreatment process of the temperature, concentration, treatment time, treatment of liquid renewal control is not strict, affecting the quality of cleaning. What is more, some new manufacturers do not use any pre-treatment for aluminum plates directly. All these will lead to poor composite quality and low 180 degree peel strength.
蕊材的選用問題。因為高分子膜與PE的粘結與其他塑料相比較效果較佳且價格適中,無毒、易加工。所以蕊材選用PE。有些小生產廠家為了降低成本選用粘結效果差且燃燒時會產生致命毒氣的PVC,或選用PE回收料或選用PE原料與下角料混合。這樣會因為PE的型號、老化程度等的不同而導致復合溫度的不同,較終表面為復合質量不穩定。
The selection of stamen material. Because the adhesion between polymer membrane and PE is the best compared with other plastics, and the price is moderate, non-toxic and easy to process. So the material is PE. In order to reduce the cost, some small manufacturers choose PVC with bad bonding effect and will produce fatal gas when burning, or choose PE recycled materials or use PE material to mix with lower corner material. This will lead to different composite temperature because of the different type of PE, aging degree and so on, and the final surface is unstable composite quality.
高分子膜的選用問題。高分子膜是一種具有特殊性能的粘結材料,它影響復合質量的主要因素。高分子膜具有兩面性,三層共擠而成。一面是與金屬粘結,另一面是與PE粘結,中間一層是PE基材,兩面的性質完全不同。兩面的材料價格相差懸殊。與鋁板店結的材料需要進口,價格昂貴。而與PE融合面的材料國內就能生產,因此有的高分子膜生產廠家就此大做文章,大量使用PE融合料以偷工減料牟取暴利。高分子膜的使用具有方向性,正反面不能掉換。高分子膜是一種自解膜,熔化不完全會導致假性復合。早期強度較高、時間一長,因風化影響會使強度降低,甚至鼓泡或開膠等現象
The selection of polymer film. Polymer membrane is a kind of adhesive material with special properties, which affects the main factors of compound quality. The polymer membrane has two sides and three layers are co extruded. One side is bonded with metal, the other side is bonded with PE, the middle layer is PE substrate, and the properties of both sides are completely different. The price of the two sides of the material is very different. The materials needed to be imported from the aluminum store are expensive. And PE fusion surface materials can be produced in China, so some polymer membrane manufacturers make a great deal of this, a large number of PE fusion materials to steal material for profit. The use of polymer membranes is directional and can not be replaced on the opposite side. Polymer membrane is a self solution membrane. Melting can not lead to false recombination. The early strength is higher and the time is longer. Because of the influence of weathering, it will reduce the strength, even bubble or glue.
