离型纸生产注意事项 Notes for release paper production:

　　离型纸原料以机械的压力，研磨等物理方式，去制成断碎的细纤维。机械纸浆以磨木纸浆为主要，其原料为阔叶树与针叶树，而这方式的生产效率能高达90-95%。

       Release paper raw material to mechanical pressure, grinding and other physical way, to make broken fine fiber. Mechanical pulp is mainly made from ground wood pulp, which is made from broadleaf and coniferous trees. The production efficiency of this method can be as high as 90-95%.

　　机械纸浆造成的纸张，因没有加添任何化学品，故木材原料的木质素，完全含於纸浆内，惟如原料中含有色物质或深色杂质，将影响未来纸张的颜色，而性质方面，它是比较脆弱，而不透明度高，排水性佳，适合高速大量抄纸。其所抄造的纸张之紧度低，平滑度高，而富弹性，吸墨能力强，可加速油墨乾燥等，印刷适应性良好。

      Mechanical pulp caused by the paper, because there is no add any chemicals, so the wood raw material lignin, completely contained in the pulp, but if the raw material contains color substances or dark impurities, will affect the future color of the paper, and the nature, it is relatively fragile, and high opacity, good drainage, suitable for high-speed large number of paper. The paper made by the low tightness, high smoothness, and rich elasticity, strong ink absorption ability, can accelerate ink drying, good printing adaptability.

　　2、离型纸化学性 Chemical properties of release paper
　　因机械纸浆留有甚多的非纤维素成份，如木质(Lignin)等，使抄造出来纸容易受光线照射使纸张的色泽有变及更脆弱的现象。为了改善这缺点，化学性的制造纸浆的方法便产生。

Because of the large amount of non-cellulose components left in mechanical pulp, such as wood, the paper is easily affected by light, which makes the color of the paper more fragile. To remedy this shortcoming, a chemical method of making pulp was developed.
　　化学纸浆是用化学品混入来蒸煮(Cooking)木材，使原料的纤维容易分离。蒸煮目的是要以化学品与木质等原料产生化学反应，以排除木质素，以留下纤维素来作纸浆的用料。

Chemical pulp is used to cook wood with chemicals that make it easier to separate the fibers from the raw material. The purpose of cooking is to create a chemical reaction with materials such as wood to remove lignin, leaving cellulose to be used for pulp.
　　因蒸煮过程中，可加入不同的化学品，使制造出来的纸浆性质有所不同，化学品可分为亚硫酸纸浆(Sulphite)、碱法纸浆(Alkaline)及硫酸盐纸浆(Kraft)。

Different chemicals can be added during the cooking process to make pulp with different properties. Chemicals are classified as sulphate pulp, Alkaline pulp and Kraft pulp.
　　亚硫酸纸浆的性质，色泽较浅，可不须经漂白步骤也可用作抄纸使用，制造的纸张，白度较高，纸质较柔软，其物理性质亦较弱。而碱法纸浆的特性，是较柔软和高不透明度，此纸浆制造的纸张，物理性质较强，主要是其纤维较短些?硫酸盐纸浆是现时比较普遍的方法。因其是用Na2S来蒸解，蒸解容易而且效果良好，而用此纸浆所造的纸张，强度较优，柔软性良好，而且耐久性佳，而经漂白後纸张白度更能大大提高。

The nature of sulphuric acid pulp, the color is lighter, can be used for paper copying without the bleaching step, the production of paper, whiteness is higher, the paper is softer, its physical properties are weaker. And alkali pulp is soft and high opacity, the paper made of this pulp, physical properties are stronger, mainly its fiber is shorter? Kraft pulp is a common method at present. Because it is steamed with Na2S, it is easy to steam and the effect is good, and the paper made of this pulp has better strength, good softness, and good durability, and the whiteness of the paper can be greatly improved after bleaching.

A method intermediate between mechanical pulp and chemical pulp. The binding force between the non-fiber component and the fiber in the raw material is dissolved first, and then the fiber is separated by mechanical means. The chemicals used in the semi chemical method are Na2SO3 and Ca(HSO3)2, with Na2CO3 and NaHCO3 acting as buffering agents. From the raw material and the properties of the pulp, fiber can reach 65-85%, made of paper, nature is hard, and this paper pulp can produce different USES, such as newsprint, printing paper, writing paper and corrugated paper and so on, the use flexibility is bigger, the cost is relatively lower than other methods when the pulp was late to the various manufacturing process, To make paper for printing. The paper making process mainly includes beating pulp, adding minerals and different fillers, and copying paper.

防粘纸，也被称为硅油纸。由三层结构组成，一层：底纸；二层：淋膜： 三层：硅油。可以用在电子产品，汽车泡沫，印刷、食品、医用等等。在大多数情况下，它是与黏性物料一起使用，特别是胶粘带。

Anti-stick paper is also known as silicone paper. It is composed of three layers. Layer 1: base paper; Layer 2: coating; Layer 3: silicone oil. It can be used in electronic products, automobile foam, printing, food, medical and so on. In most cases, it is used with adhesive materials, especially adhesive tape.

湿法生产预浸料时，在预浸料的上下均放置离型纸，其中下离型纸随着预浸料的收卷存附其中，所以预浸料表面通常有一层离型纸保护。离型纸的作用是防止预浸料被污染，又可为在其表面划线提供方便。离型纸的另一个作用是防止单向预浸料的横向开裂。

In wet prepreg production, release paper is placed on the upper and lower parts of the prepreg, and the lower release paper is attached with the rewinding of the prepreg, so the surface of the prepreg is usually protected by a layer of release paper. The function of the release paper is to prevent the prepreg from being polluted, and to provide convenience for marking on its surface. Another function of release paper is to prevent transverse cracking of unidirectional prepreg.

一、这种纸在贴的时候很好撕下来，但在一个周期(24小时)以后就难剥离，三个周期就拉不掉了。 这样的离型纸主要是不稳定，纸张密度不好、涂布不均匀、它的防渗透力差，所以在贴一个周期的时候，胶能渗透到离型纸里面，所以无法剥离!所以必须更换密度比较好的，纸张比较好的，涂硅均匀的，比较稳定的纸张做低纸。

Firstly, this kind of paper is good to tear off when sticking, but it is difficult to peel off after a cycle (24 hours), and three cycles can not be pulled off. This release paper is mainly unstable, paper density is not good, uneven coating, its permeability is poor, so when pasting a cycle, the glue can penetrate into the release paper, so it can not be peeled! So we must replace the density is better, the paper is better, coated with uniform silicon, more stable paper to do low paper.

二、进口双面胶的剥离不良，很多胶带都会有这个现象，因为进口的双面胶的物性都不一样，常规用的主要有3M、日东、索尼、积水、TESA等，有无基材的有基材的，很多厂商为了方便就用一种底纸来模切，所以导致剥离不良。所以必须判断好胶带的粘性，在胶带的粘性差比较大的情况下把底纸分开使用。

Secondly, the peeling of imported double-sided adhesive tape is bad, many tapes will have this phenomenon, because the physical properties of imported double-sided adhesive tape are not the same, the conventional use of 3M, Japan, SONY, water, TESA, there is no substrate with substrate, many manufacturers in order to facilitate the use of a base paper to die cutting, so lead to poor stripping. Therefore, it is necessary to judge the viscosity of the tape, and separate the base paper in the case of a large viscosity difference of the tape.

三、平时用来贴的这款胶带都可以，但是模切以后很难排废或者是因为产品太小不能剥离。这样的情况呢就要注意了，有的是排废过程中容易把产品带起，这说明剥离力太轻，可以选择稍重一点的试一下。如果是不能剥离或剥离不良这样的情况也很正常(特别是无基材的)，因为产品面积过小，在剥离力不够轻在剥离的时候就容易造成变形等现象，所以必须用更轻的离型纸。  因为现在有很多用户都反映有这种现象,其实离型纸不能完全靠刚开始的离型力来判断离型纸的本质,因为不同的涂布方式'不同的原纸都会有不同的离型力周期.还有就是离型纸的防渗透力,市场上还有一种格拉辛是用蜡硅油涂的,表面很漂亮,而且刚开始帖贴合的时候离型力很轻,但过几天后就撕不下来等现象,所以我建议用格拉辛最好还是用正品,不要用那些乱码的.3M9460的胶性比较粘,所以离型纸必须用涂布均匀,轻离型的离型纸,建议用无溶剂上硅的离型纸.  大家在选择离型材料的时候，要做三个周期的测试，更应该做15天的高温高湿测试。 只有通过了这样严格要求的离型纸，才是真正可靠的离型纸。

Thirdly, usually used to paste the tape can be, but it is difficult to discharge waste after die cutting or because the product is too small to peel. In this case, we should pay attention to the fact that some of the products are easy to take up in the waste discharge process, which shows that the stripping force is too light. You can choose to try a little heavier. If it is not peeling or peeling bad such a situation is also very normal (especially no substrate), because the product area is too small, in the peeling force is not light enough in the peeling when it is easy to cause deformation and other phenomena, so you must use lighter release paper. Because now a lot of users have reflected this phenomenon, in fact, the release paper can not completely rely on the beginning of the release force to judge the nature of the release paper, because different coating methods' different base paper will have different release force cycle. And from type paper anti seepage force, the market is also a gration is made of silicone oil wax coating, the surface is very beautiful, and just began to post fit mold force is very light, but after a few days can't tear down and wait for a phenomenon, so I suggest using gration would better use an authentic, don't use the gibberish.3M9460 comparison of glue stick, so the mold must be coated uniformly, For light release paper, it is recommended to use solvent-free silicon release paper. When choosing release material, three cycles of testing should be done, and 15 days of high temperature and high humidity test should be done. Only through such strict requirements of the release paper, is really reliable release paper.
