原纸技术目标与瓦楞纸箱强度有关系吗?

来源:https://www.gtmfpack.com 发布时间:2021-06-30

定量 又称为克重,它是指每平方米纸的分量,用g/m2体现。定量的策画公式为:试样称量/试样的面积。定量是权衡纸张物理功能的重要目标,相同通常来说,纸的 定量高,它的抗张强度、环压强度、扯破度、挺度和厚度目标相对就高。用高定量的纸材制作瓦楞纸箱,其抗压强度相对就高些。所以,要制作强度高的瓦楞纸箱, 客户的底子要求之一是挑选高定量的纸材。
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.
紧度 它是指每立方厘米纸张的分量,用g/cm3来体现。其策画公式为:
Tightness refers to the weight of paper per cubic centimeter, expressed in g / cm3. The planning formula is as follows:
纸的紧度怎样,反响了它的纤维构造布局的疏密水平。箱板纸和瓦楞纸的紧度值高,它们的耐破度、环压强度、耐拆穿和抗张功能相对就好,那么,纸箱的集体强度 相对也就高。可是,若紧度过大,纸材简单脆裂,尤其是白板纸,紧度值若明显大于标准,其耐折度功能将会有所下降。
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,用白板纸作面层裱合的瓦楞纸板,不 宜接收紧度过高的白板纸,以免影响纸箱摇盖的耐折度。
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.

施胶度 纸张、纸板在出产时,施加必定量的松香胶等耐水性的胶体物后,使纸面增加抗水性,这种出产加工工艺称为施胶。施胶度是权衡胶量巨细的质量目标,依据国度标 准,可接收墨水划线法和表面汲取分量法举办检测。工场也可敷衍了事,用“滴水法”检测纸面的施胶度。其做法是:在纸面滴一点水,若水点洇渗速率快,说明施 胶度欠好;若水点不易呈现洇渗征象,水珠浮在纸面上,说明施胶度就好。制作瓦楞纸箱的原纸,要求施胶度要好,多么不易吸湿,纸箱的含水率安定,可较好地保 证纸箱的强度。
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 所谓含水率是指纸或纸板中水分的含量,用百分比体现,其查验的策画公式为:
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:
含水率成为纸箱的三个重要缺点查验项目之一的重要原因原由。当纸箱的含水率偏高时会使得其耐拆穿抗压强度和耐破 强度等功能会有所下降。瓦楞纸具有必定的耐压、抗张、耐折功能和抗拆穿,水分含量过高会使得纸质就显得柔软、挺度差,压楞和粘合质量也差。要是水分明显低于下极限标准值时,压楞时就简单呈现破碎征象。要是瓦楞纸和箱板纸的水分含量悬殊过大时,单面机加工出来的瓦楞纸板,就简单呈现弯曲,下工序裱适时就简单呈现起泡和脱胶征象,使纸箱的强度明显下降。
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 纸箱作为一种包装容器,其摇盖需常常作开启运动,这就要求纸材应具有必定的耐折身手。纸的横向耐折度是测定纸在必定的张力、速率和视点条件下,对 150?15mm标准的试样作1350角的往复性折叠实验,当纸样开裂时,即为耐折度的查验次数。制作箱板纸和折板纸的浆料特性、纸的含水率、紧度、纤维长度和联协力的牢度以及原纸受寄存时刻和温度等要素的影响,很大水平上决定着原纸的耐折度。要前进纸箱的耐折度功能,做好原材料的质量把关是重要的一环。
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.
