在离型纸的选择方面,主要考虑到成本,产品质量,生产程序,所备产品的特性及使用情况!所备产品特性:现在国内较常用的进口胶带3M,日东,索尼,德莎及一些国产胶带.因为不同的胶带胶水特性不同.这决定了我们在选择离型纸的时候要考虑此方面的情况。
In the choice of paper, we mainly consider the cost, product quality, production procedures, prepared product characteristics and use of the situation! Product features: now the most commonly used are imported tape 3M, Japan, SONY, Desa and some domestic tape because different tapes have different adhesive properties. This determines that we should consider this aspect when choosing the release paper. Cost: there is a big difference between domestic and imported release paper.
成本:国内和进口的离型纸有很大区别,普遍来说国产离型纸的口啤并不是很好,比如有时备胶时会出现表面离型不良,不能够把离型纸和产品很好的撕开的情况,当然目前国内的技术成熟后此方面的情况已很少出现.国内的离型纸肯定比进口的便宜.并且有一个比较大的价格差,公司需综合来考量。
Generally speaking, the public praise of domestic release paper is not very good. For example, sometimes there will be poor surface release when glue is prepared, and the release paper and product can not be torn well. Domestic release paper is certainly cheaper than imports. As there is a relatively large price difference, the company needs to consider comprehensively.
深圳离型纸厂由于气候的关系,电子模切工业冬季宜选用剥离力偏重的离型纸,夏季宜选用剥离力偏轻的离型纸。特殊需求的胶带,在模切过程中使用的离型纸,需与离型供应商接洽。在作深度测试、对比后方可进行生产活动,以免成品产生质量问题。涂胶厂一般均选用高涂布量的离型纸,而复合厂一般均选用中等涂布量的离型纸,若是热复合,也需要选择高涂布量的离型纸,水胶仅需要低涂布量的离型纸即可,中等涂布量的离型纸适合油胶及保护膜使用,高涂布量的离型纸不适合保护膜使用。生产程序:这里重点是是否要冲压或者切割,一般涉及到冲压或者切割时,会要求离型纸的厚度,因为低克重的离型纸在用于冲压的时候,不易冲断,当然,这也和底纸的易碎度有关,易碎度不好的底纸在冲压或者切割的时候会把纸和产品撕开.达不到理想或者说想要的效果。
Due to the impact of the climates, electronic die cutting industry in winter should choose the release of heavy peeling force paper, in summer should choose the release of light peeling force paper. Special requirements of tape, in the process of die cutting to use the release paper, need to contact with the release supplier. Production activities can be carried out after in-depth testing and comparison to avoid quality problems in finished products. Glue factory generally selects the high amount of coating from type paper, and the composite factory general medium was used for the coating weight from type paper, if thermal compound, also need to choose high coating weight from type paper, glue water only need lower coating weight from type paper, medium coating weight from type paper suitable for oil glue and protective film, high coating weight from type paper is not suitable for protective film. Production process: the focus here is whether to stamping or cutting, generally involves the stamping or cutting, will demand from the thickness of the paper, because of the low gram from type paper when used for stamping, difficult thrust, of course, this also and bottom paper fragile degrees, fragile degree of bad bottom paper at the time of stamping or cutting will tear the paper and products. Do not achieve the desire effect.
离型纸的分类,可以按有塑离型纸和无塑离型纸分类;有塑离型纸,因为离型剂具有一定的渗透性能,如果没有一定的阻隔,离型剂会渗透到纸张内部,造成固化不良以及离型剂使用量偏大(成本过高)等诸多不良因素。所以需要在纸上做涂塑处理(俗称淋膜),国内一般使用聚乙烯(PE)粒子进行淋膜,要求熔融指数在7左右,国产PE粒子一般选用石化的1C7A。
Release paper can be classified by plastic release paper and non-plastic release paper. Plastic release paper, because the release agent has a certain permeability, if there is no certain barrier, the release agent will penetrate into the paper, resulting in poor curing and release agent usage (high cost) and many other adverse factors. So need to do plastic coating on paper (commonly known as film), domestic generally use polyethylene (PE) particles for film, melting index is required in about 7, domestic PE particles generally choose petrochemical 1C7A.
