15人圆餐桌电动尺寸 香河县电动餐桌价格

 

以前小的时候（70-80年代左右，老家的长沙发、椅子、木床等）都是自家自留山（杉树、松木）的原木砍伐回来，晾干到一定的时候（水分蒸发），再拉到加工厂进行切割成一块块板材和方条，然后请木工师傅纯手工制作，那时候没有复合胶水拼接的说法，纯粹就是依靠铁钉等固定各式家居的各个角落，而且质量也是杠杠的;;原木、纯手工制作，如此方式环保的豪华电动餐台板材。15人圆餐桌电动尺寸  香河县电动餐桌价格

 

  现在不管是颗粒板、纤维板、复合板材等都或多或少加入了具有化学成分的胶水（就连此类木材本身也含有一定的甲醛），甲醛、苯、氨等成分融入其中，而且需要一定的时间（短则一年半载，长达数十年才能挥发完毕），想办环保健康比较难。   不同的板材由于握钉力，承载力，防潮等te性不一样用途也是不一样的。关于环保国家是有标准的，对于甲醛等有害物质含量有严格规定至少是E1级别的。

When I was a child (around the 1970s and 1980s, the couch, chair, wooden bed, etc. in my hometown) were all cut back from the logs of my own mountain (fir, pine), dried to a certain time (water evaporation), then pulled to the processing plant to cut into pieces of plates and square strips, and then asked the carpenter to make them by hand. At that time, there was no saying of composite glue splicing, and it was simply relying on iron nails to fix various corners of the home, And the quality is also competitive;; The luxurious electric dining table board made of logs and pure handmade in this way is environmentally friendly. Now, whether it is particle board, fiberboard, composite board, etc., all have more or less added glue with chemical composition (even such wood itself contains certain formaldehyde), and formaldehyde, benzene, ammonia and other components are integrated into it, and it takes a certain time (for a short time of one year and a half, and it takes decades to volatilize), so it is difficult to achieve environmental protection and health. Different plates have different uses due to different nail holding capacity, bearing capacity, moisture resistance and other te properties. There are national standards on environmental protection, and there are strict regulations on the content of harmful substances such as formaldehyde, which is at least E1 level.

 

 

 

从板材的分类上来说指接板，多层板比较环保。也是我们常说的实木板材豪华电动餐台。颗粒板刨花板由于承载力握钉力都比较好，但是不容易铣型，一般都做柜体。环保级别也是比较高的。密度板铣型比较容易。一般做柜门比较多。环保级别仅次于颗粒板。大芯板的由于含有的胶比较多。相对来说不太环保。 下面是板材的科普★生态板  生态板如果按照广义来分，也叫免漆板或者三聚氰胺板，全称是三聚氰胺浸渍胶膜纸饰面人造板。是将带有不同颜色或纹理的纸放入生态板树脂胶粘剂中浸泡，然后干燥到一定固化程度，将其铺装在刨花板、防潮板、中密度纤维板、胶合板、细木工板或其他硬质纤维板表面，经热压而成的装饰板。但这次我们评测定义的生态板，是以细木工板或大芯板为主，15人圆餐桌电动尺寸  香河县电动餐桌价格可以从横截面上看出蛛丝马迹。如果有店家声称其店里的生态板如何如何，可以看看横截面。 评测中的生态板样品截面图（三聚氰胺贴皮）

In terms of the classification of plates, the multi-layer plates are more environmentally friendly. It is also the luxury electric dining table made of solid wood. Particle board particleboard has good bearing capacity and nail holding capacity, but it is not easy to be milled. Generally, it is made of cabinet. The environmental protection level is also relatively high. It is easy to mill the density board. Generally, there are more cabinet doors. The environmental protection level is second only to particle board. The large core board contains more glue. Relatively speaking, it is not environmentally friendly. The following is the popular science ★ ecological board ecological board, which is also called lacquer-free board or melamine board in a broad sense. It is also called melamine impregnated adhesive paper veneer wood-based board. It is a kind of decorative board made by immersing paper with different colors or textures in the resin adhesive of the ecological board, drying it to a certain degree of curing, paving it on the surface of particleboard, moisture-proof board, medium-density fiberboard, plywood, blockboard or other hard fiberboard, and then hot-pressing it. However, the ecological board defined in our evaluation this time is mainly blockboard or large-core board, which can be seen from the cross section. If a shopkeeper claims how the ecological board in his shop is, you can look at the cross section. Cross-sectional view of ecological board sample under evaluation (melamine coating)

 

 

 

 

生态板之所以称生态，是相对于颗粒板，所用胶水要少，但不代表它就不用胶没有甲醛。按照本次评测的数据，我们不得不怀疑生态板的环保性是否能如商家宣传的零醛或者少醛。便宜的生态板门道很多。芯材，价格较便宜的生态板芯材大多采用的是回收的建筑废料。以松木芯生态板为例，首先回收后，进行简单去掉外层杂物，锯成所需要的尺寸，然后用胶粘接成整版或者半板芯材。而表板加工则是将一层油墨纸经高温粘合在表板上，再然后是将两层表板分别用胶经高温粘合在芯板上。后裁边，一块生态板就制成了。15人圆餐桌电动尺寸  香河县电动餐桌价格面板两次会用到胶，而这个胶用得好不好，用的是脲醛胶还是MDI，就看品牌商的良心了。胶水的种类在地板评测中也有表述过，也不再这里赘述。另外，装修公司和木工师傅也比较喜欢用生态板，施工很方便。★细木工板   细木工板一般也称为大芯板。   和生态板的区别就在于，表面与背面没有做贴皮处理。所以意味着细木工板的胶要比生态板至少少用两层。相对来说会比生态板更好一些。                           （细木工板的表面）                       （细木工板的横截面）★实木颗粒板

The reason why the ecological board is called ecological is that it uses less glue than the particle board, but it does not mean that it does not need glue or formaldehyde. According to the data of this evaluation, we have to doubt whether the environmental protection of the ecological board can be as zero or less formaldehyde as advertised by the merchants. There are many cheap ecological plank doorways. The core material, the cheaper core material of ecological board, is mostly recycled construction waste. Take the pine core ecological board as an example. First, after recycling, simply remove the outer debris, sawn it to the required size, and then glued it to form the whole or half board core material. The processing of the surface plate is to glue a layer of ink paper onto the surface plate at high temperature, and then glue the two layers of surface plate onto the core plate at high temperature. After trimming, an ecological board is made. The panel will use glue twice, and whether the glue is used well depends on the conscience of the brand. The type of glue has also been described in the floor evaluation, and will not be described here. In addition, decoration companies and carpenters also prefer to use ecological boards, which is very convenient for construction. ★ Joinery board joinery board is generally also called large core board. The difference from the ecological board is that the surface and the back are not covered. So it means that the glue of blockboard is at least two layers less than that of ecological board. Relatively speaking, it will be better than the ecological board. (surface of blockboard) (cross section of blockboard) ★ solid wood particle board

 

 

 

 

 

实木颗粒板也算是刨花板的一种，如果加了防潮颗粒的也叫防潮板。   实木颗粒板是由木材或其他木质纤维素材料制成的碎料，两边使用细密木纤维，中间夹长质木纤维，施加胶粘剂后在热力和压力作用下胶合成的人造板，以刨花板的工艺生产的板材。                        （实木颗粒板横截面）   现在的大品牌都比较喜欢用实木颗粒板，te别是用在定制豪华电动餐台上，因为颗粒板的抗变形能力，抗开裂能力高于除密度板之外的其他板材，抓合力高于密度板和部分生态板，防潮能力高于密度板，握钉力也可以。从物理性能上来说，算是适合做品牌定制类豪华电动餐台的了。品牌定制颗粒板，环保性都不算te别好，虽然勉强可以划分E1级，但如果温度稍高，封边处理又一般的话，甲醛依旧会有泄露，所以远远没有达到真正环保的标准。关键点还是在用胶上，小厂代工贴牌还是大厂制作，都逃不过这个问题。不解决源头，倒霉的还是我们消费者。★OSB欧松板   按大类分，OSB欧松板也属于刨花板。

Solid wood particle board is also a kind of particle board. If moisture-proof particles are added, it is also called moisture-proof board. Solid wood particle board is a kind of wood-based board made of wood or other lignocellulosic materials, with fine wood fiber on both sides and long wood fiber in the middle. After applying adhesive, it is glued under the action of heat and pressure. It is produced by the process of particleboard. (Cross section of solid wood particle board) Most of the major brands now prefer to use solid wood particle board, especially te, which is used on the customized luxury electric dining table, because the particle board's deformation resistance and cracking resistance are higher than other boards except for the density board, its grip is higher than the density board and some ecological boards, its moisture resistance is higher than the density board, and its nail grip is also OK. In terms of physical performance, it is suitable for making brand customized luxury electric dining table. The brand customized particle board is not good for environmental protection. Although it can be divided into E1, if the temperature is slightly higher and the edge sealing treatment is normal, formaldehyde will still leak, so it is far from reaching the standard of real environmental protection. The key point is the use of glue. Whether small factories produce OEM labels or large factories produce them can't escape this problem. If we don't solve the source, it is our consumers who are unlucky. ★ OSB European pine board is divided into large categories, and OSB European pine board also belongs to particleboard.

 

 

 

 

OSB欧松板的大te征在于，颗粒板的碎料是一粒粒的，欧松板的则是一片片的。物理性能上如握钉力，会比实木颗粒要好，但价格也会贵不少。至于环保性能是不是比实木颗粒好，就不一定了。                          （OSB欧松板的表面）★多层板   多层板，是由一层层实木薄板（山樟、柳按、杨木、桉木等），按照木纹方向相互垂直放置胶合而成，通常用奇数层单板。也叫胶合板。按根据厚度也可以叫3-9厘板，和地板中的实木复合地板一样，每层之间都用到胶。这也是现在酒店豪华电动餐台厂家用得多的原材料。

The big characteristic of OSB Eurosone plate is that the particles of the particle plate are granular, while the Eurosone plate is piecemeal. Physical properties, such as nail grip, will be better than solid wood particles, but the price will also be much more expensive. Whether the environmental protection performance is better than that of solid wood particles is uncertain. (The surface of OSB European pine board) ★ Multi-layer board is made of a layer of solid wood sheets (camphor, willow, poplar, eucalyptus, etc.), which are vertically placed and glued according to the direction of the wood grain, usually with odd layers of veneer. Also called plywood. According to the thickness, it can also be called 3-9 cm board. Like the solid wood composite floor in the floor, glue is used between each layer. This is also the raw material used by the luxury electric dining table manufacturers in the hotel.

多层板优点有变形小、幅面大、施工方便、不翘曲、横纹抗拉力学性能好，物理性能比其他类型的板材好，更加可靠，所以木工和装修公司也经常推荐。不过含胶量大，价格略高。                         （多层板横截面）★密度板    密度板，家用的多为中密度纤维板（MDF，密度0.4～0.8g/cm³）和高密度纤维板（HDF，密度大于0.8g/cm³）。密度板是把木材尾料打成粉碎，然后重新加胶粘合，和木材相差甚远。可以参考地板中的强化复合板（一般用HDF），原理上一致。中密度纤维板价格相对便宜，容易加工和造型简单，一般用来做不需要承重如柜体或隔板，需要造型的部分，例如柜门等。                             （密度板横截面）★指接板

Multi-layer board has the advantages of small deformation, large size, convenient construction, no warping, good transverse tensile resistance, and better physical properties than other types of boards, which are more reliable, so woodworking and decoration companies often recommend it. However, the glue content is large and the price is slightly higher. (Cross section of multilayer board) ★ Density board density board, most of which are medium density fiberboard (MDF, density 0.4-0.8g/cm³) and high density fiberboard (HDF, density greater than 0.8g/cm³). The density board is to smash the wood tailings and then glue them again, which is very different from wood. You can refer to the laminate in the floor (generally HDF), which is consistent in principle. Medium density fiberboard is relatively cheap, easy to process and simple to shape. It is generally used to make parts that do not need to bear weight, such as cabinet body or partition, but need to be shaped, such as cabinet door. (Cross section of density board) ★ Finger board
