在離型紙的選擇方面,主要考慮到成本,產品質量,生產程序,所備產品的特性及使用情況！所備產品特性:現在國內較常用的進口膠帶3M，日東，索尼，德莎及一些國產膠帶．因為不同的膠帶膠水特性不同.這決定了我們在選擇離型紙的時候要考慮此方面的情況。

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:國內和進口的離型紙有很大區別,普遍來說國產離型紙的口啤并不是很好，比如有時備膠時會出現表面離型不良,不能夠把離型紙和產品很好的撕開的情況，當然目前國內的技術成熟后此方面的情況已很少出現．國內的離型紙肯定比進口的便宜.并且有一個比較大的價格差，公司需綜合來考量。

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.

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.

     離型紙的分類，可以按有塑離型紙和無塑離型紙分類；有塑離型紙，因為離型劑具有一定的滲透性能，如果沒有一定的阻隔，離型劑會滲透到紙張內部，造成固化不良以及離型劑使用量偏大（成本過高）等諸多不良因素。所以需要在紙上做涂塑處理（俗稱淋膜），國內一般使用聚乙烯（PE）粒子進行淋膜，要求熔融指數在7左右，國產PE粒子一般選用石化的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.

離型紙也就是硅油紙或者防粘紙，主要用來隔離帶有粘性的物體。那一張格拉辛離型紙生產出來什么樣的條件才算好的。下面和你一起去了解生產格拉辛離型紙應該具備什么樣的條件。

離型紙主要有以下幾點特征：

第一離型紙的防潮，耐溫等。離型紙中含有硅油，而硅油具有一定的耐溫性，但這主要在于產品的運用，以及國產和進口硅油選擇的。一般硅油溫度可達到150度左右。

第二離型紙的剝離力：剝離力是指產品是否可以輕易撕落，當然這有嚴格的測試程序。小型分切機，國際目前主要采用國標的.剝離力的單位是克。依照測試的結果不一樣，一般分為三個程序，輕、中、重離型.輕離型是指當離型紙和膠帶護膜貼合時可以輕易剝離，而中離型則是不是很容易剝離，而重離型是很難剝離。

第三離型紙的清潔度：其實就是指外觀的清潔和清潔度。因為離型紙廠家的工作環境不同，幾乎很難得是在無塵作事室里，一般情況下，廠房好一點的會在環保和環境方面都有很大的優勢，因為這些都會對清潔度出現影響.很多離型紙的清潔度不是在生產過程中遭到污染的.很大程度是由于在分切的時候，由于分切廠家的清潔度不高，釀成靜電吸附才出現灰塵。

在了解掌握了離型紙一些特性之后，現在我們再了解一下生產格拉辛離型紙時，要滿足哪些條件呢？

一、要能夠粘住預浸料，但是有要易于讓兩者分離；

二、不和樹脂體系發生化學反應或者會污染樹脂體系；

三、離型紙在受到牽引后它的伸長率還要能和纖維保持一致，從而防止預浸料在制備過程中因為牽伸不同步從而引起的變形或扭曲，不過一般來說，它的厚度、單位面積、質量都不是那么容易的精確控制；

四、要具有足夠的致密性，這樣就能防止水分通過它從而進入預浸料中；

五、即使是環境的溫濕度發生變化時，離型紙的長度、寬度都能夠保持不變，從而避免引起離型紙起皺使的預浸料皺折。

1、干凈度：是指表面的干凈和清潔度，因為離型紙廠家的生產環境不盡相同，大多數不是無塵工作室，由于成本的問題，也不可能采用無塵工作室，一般來說都是普通的廠房，好一點的會在環保和環境方面有很多的改進，這些都會對干凈度產生影響。2、離型度：指離型紙的離型程度，在這點沒有絕對的值，看每個廠家的配方不同來決定。3、剝離力：是指當產品撕落時是否容易，當然這有嚴格的測試標準。補充： 離型紙又稱隔離紙、防粘紙、硅油紙。是一種防止預浸料粘連，又可以保護預浸料不受污染的防粘紙。

1, Degree of cleanness: refers to the clean surface and cleanliness, because the paper factory production environment is not the same, most is not dust-free workshop; because of the cost of the problem, it is also difficult to use dust-free workshop. In general are all common factories, the better one will have a lot of improvement in environmental protection , which will have an effect on the clean. 2, Degree of release: refers to the degree of release paper, at this point there is no absolute value, depending on the formula of each manufacturer to decide. 3, Peeling force: refers to whether it is easy to tear off the product, of course, there are strict test standards. Supplement: Release paper is also called isolation paper, anti-stick paper, silicone paper. It is a kind of anti-stick paper to prevent adhesion of prepreg material and protect prepreg material from pollution.

用途：（1）格拉辛（底紙為格拉辛）硅油紙：耐高溫、防潮、防油，一般用于食品行業包裝。（2）普通離型紙：防潮、防油，起到產品的隔離作用，適用行業：電子、汽車泡棉、印刷等，它的使用范圍大部分和具有黏性的在一起，特別是膠帶，所以，一般要用到膠帶的產品都會用到離型紙。（3）PVC壁紙，PVC皮革涂布發泡過程承接作用。

Usage: (1) Geraxin (base paper for Geraxin) silicone paper: high temperature resistance, moisture-proof, oil-proof, generally used in food industry packaging. (2) Ordinary release paper: moisture-proof, oil-proof, play the role of product isolation, applicable industry: electronics, automobile foam, printing, etc., its use scope and most of the sticky together, especially tape, so generally use tape products will use release paper. (3) PVC wallpaper, PVC leather coating foaming process to undertake the role.

在離型紙的選擇方面，主要考慮到成本、產品質量、生產程序、所備產品的特性、使用情況。

1、所備產品特性：國內較常用的膠帶為韓國的三芝、日本的日東、美國的三M等，因為不同的膠帶膠水特性不同，這決定了我們在選擇離型紙的時候要考慮該方面的情況。

2、成本：國內和進口的離型紙有很大區別，普遍來說國內的離型紙的口碑并不是非常好，特別是體現在三M的膠帶和日東的膠帶，經常會出現表面有霧狀或者離型度太低，不能夠把離型紙和產品很好的撕開的情況。只是國內的離型紙肯定比進口的便宜，并且有一個比較大的價格比，如果考慮到公司的產品是出口所用，當然最好建議使用進口的離型紙，在出關方面會比較順利；由于國產離型紙的生產設備及生產水平的特點，決定了國產離型紙在某些產品上的不穩定性，嚴重的后果就是會造成膠帶的浪費。

3、生產程序：這里重點是是否要沖壓或者切割，一般涉及到沖壓或者切割時，會要求離型紙的厚度，因為低克重的離型紙在用于沖壓的時候不易沖斷，當然，這也和底紙的易碎度有關，易碎度不好的底紙在沖壓或者切割的時候會把紙和產品撕開，達不到理想或者說想要的效果。

4、使用情況：這點主要體現在有些產品只是需要在運輸過程中保持產品的平衡度，那么它會要求產品和離型紙結合時不易跌落。

關于離型紙的選擇，主要是適合，在個人理解來說，沒有絕對好的，也沒有絕對壞的，國產有國產的優勢，進口也有進口的強項。離型紙的選擇等于是一個高考的過程，因為要綜合考慮所有的因素，在各種因素均衡的情況下達到一個合理又能降低成本的效果。
