原紙技術目標與瓦楞紙箱強度有關系嗎?

定量 又稱為克重,它是指每紙的分量,用g/m2體現。定量的策畫公式為:試樣稱量/試樣的面積。定量是權衡紙張物理功能的重要目標,相同通常來說,紙的 定量高,它的抗張強度、環壓強度、扯破度、挺度和厚度目標相對就高。用高定量的紙材制作瓦楞紙箱,其抗壓強度相對就高些。所以,要制作強度高的瓦楞紙箱, 客戶的底子要求之一是挑選高定量的紙材。
Quantitative, also known as gram weight, refers to the weight per square meter of paper, expressed in g / m2. The quantitative planning formula is: sample weight / sample area. Quantitative is an important goal to balance the physical function of paper. Generally speaking, the paper with high quantitative has relatively high tensile strength, ring crush strength, tear, stiffness and thickness. Using high quantitative paper to make corrugated box, its compressive strength is relatively higher. Therefore, to make high-strength corrugated boxes, one of the basic requirements of customers is to select high-quality paper materials.
緊度 它是指每立方厘米紙張的分量,用g/cm3來體現。其策畫公式為:
Tightness refers to the weight of paper per cubic centimeter, expressed in g / cm3. The planning formula is as follows:
紙的緊度怎樣,反響了它的纖維構造布局的疏密水平。箱板紙和瓦楞紙的緊度值高,它們的耐破度、環壓強度、耐拆穿和抗張功能相對就好,那么,紙箱的集體強度 相對也就高??墒?,若緊度過大,紙材簡單脆裂,尤其是白板紙,緊度值若明顯大于標準,其耐折度功能將會有所下降。
The tightness of paper reflects the density of its fiber structure. If the tightness value of cardboard and corrugated paper is high, their bursting strength, ring crush strength, tear resistance and tensile function are relatively good, then the collective strength of carton is relatively high. However, if the tightness is too large, the paper material is simple and brittle, especially the white board, if the tightness value is significantly greater than the standard, its folding function will be reduced.
所以,用白板紙作面層裱合的瓦楞紙板,不 宜接收緊度過高的白板紙,以免影響紙箱搖蓋的耐折度。
Therefore, it is not suitable for corrugated board with white board as surface layer to receive white board with too high tightness, so as not to affect the folding resistance of carton cover.

施膠度 紙張、紙板在出產時,施加必定量的松香膠等耐水性的膠體物后,使紙面增加抗水性,這種出產加工工藝稱為施膠。施膠度是權衡膠量巨細的質量目標,依據國度標 準,可接收墨水劃線法和表面汲取分量法舉辦檢測。工場也可敷衍了事,用“滴水法”檢測紙面的施膠度。其做法是:在紙面滴一點水,若水點洇滲速率快,說明施 膠度欠好;若水點不易呈現洇滲征象,水珠浮在紙面上,說明施膠度就好。制作瓦楞紙箱的原紙,要求施膠度要好,多么不易吸濕,紙箱的含水率安定,可較好地保 證紙箱的強度。
Sizing paper, paperboard in the production, the application of a certain amount of rosin and other water-resistant colloidal matter, so that the paper surface to increase water resistance, this production process known as sizing. Sizing degree is the quality target to weigh the size of sizing amount. According to the national standard, it can be detected by ink marking method and surface absorption component method. Workshop can also be perfunctory, with the "dripping method" to detect the sizing degree of paper. The method is: drop a little water on the surface of the paper, if the water point bleeding rate is fast, it means that the sizing degree is not good; If the water spot is not easy to show the sign of bleeding, and the water drops float on the paper surface, it means that the sizing degree is good. The base paper for making corrugated box requires good sizing degree, how difficult it is to absorb moisture, and the moisture content of the box is stable, which can better ensure the strength of the box.
含水率 所謂含水率是指紙或紙板中水分的含量,用百分比體現,其查驗的策畫公式為:
Moisture content the so-called moisture content refers to the moisture content of paper or paperboard, which is expressed in percentage. The planning formula for checking is as follows:
含水率成為紙箱的三個重要缺點查驗項目之一的重要原因原由。當紙箱的含水率偏高時會使得其耐拆穿抗壓強度和耐破 強度等功能會有所下降。瓦楞紙具有必定的耐壓、抗張、耐折功能和抗拆穿,水分含量過高會使得紙質就顯得柔軟、挺度差,壓楞和粘合質量也差。要是水分明顯低于下極限標準值時,壓楞時就簡單呈現破碎征象。要是瓦楞紙和箱板紙的水分含量懸殊過大時,單面機加工出來的瓦楞紙板,就簡單呈現彎曲,下工序裱適時就簡單呈現起泡和脫膠征象,使紙箱的強度明顯下降。
Moisture content has become one of the three important shortcomings of carton inspection items. When the moisture content of the carton is too high, it will make the function of bursting strength and bursting strength decline. Corrugated paper has a certain pressure, tension, folding function and tear resistance, too high moisture content will make the paper appear soft, poor stiffness, corrugated and bonding quality is also poor. If the moisture content is obviously lower than the lower limit standard value, it will simply show the sign of breakage when pressing. If the moisture content difference between corrugated paper and cardboard is too large, the corrugated paper produced by single-sided machining will simply show bending, and the next mounting process will simply show signs of blistering and degumming, so that the strength of the carton will be significantly reduced.
耐折度 紙箱作為一種包裝容器,其搖蓋需常常作開啟運動,這就要求紙材應具有必定的耐折身手。紙的橫向耐折度是測定紙在必定的張力、速率和視點條件下,對 150?15mm標準的試樣作1350角的往復性折疊實驗,當紙樣開裂時,即為耐折度的查驗次數。制作箱板紙和折板紙的漿料特性、紙的含水率、緊度、纖維長度和聯協力的牢度以及原紙受寄存時刻和溫度等要素的影響,很大水平上決定著原紙的耐折度。要前進紙箱的耐折度功能,做好原材料的質量把關是重要的一環。
Folding carton as a kind of packaging container, its swing cover often needs to be opened, which requires that the paper material should have a certain folding ability. The lateral folding resistance of paper is to measure the bending resistance of 150? Mm paper under certain tension, speed and viewpoint conditions? When the paper sample is cracked, it is the inspection times of folding resistance. The properties of pulp, moisture content, tightness, fiber length and joint fastness, and the influence of storage time and temperature on the folding resistance of base paper are the key factors for making cardboard and folding paper. In order to improve the folding function of cartons, it is important to control the quality of raw materials.
