无纺布是什么?
nonwovens
无纺布又称不织布、针刺棉、针刺无纺布等,采用聚酯纤维,涤纶纤维(简称:PET)材质生产,经过针刺工艺制作而成,可做出不同的厚度、手感、硬度等。 无纺布具有防潮、透气、柔韧、轻薄、阻燃、无毒无味、价格低廉、可循环再用等特点。可用于不同的行业,比如隔音,隔热,电热片,口罩,服装,医用,填充材料等
优点:
1.质轻:以聚丙烯树脂为主要生产原料,比重仅0.9,只有棉花的五分之三,具蓬松性,手感好。
2.柔软:由细纤维组成(2-3D)轻点状热熔粘结成型。成品柔软度适中,具舒适感。
3.拨水、透气:聚丙烯切片不吸水,含水率零,成品拨水性佳,由100%纤维组成具多孔性,透气性佳,易保持布面干爽、易洗涤。
4. 可以净化空气,利用孔小的优点,将细菌病毒拒之门外。
5. 无毒、无刺激性:产品采用符合FDA食品级原料生产,不含其他化学成分,性能稳定,无毒、无异味,不刺激皮肤。
6.抗菌、抗化学药剂:聚丙烯属化学钝性物质,不虫蛀,并能隔离存在液体内细菌及虫类的侵蚀;抗菌、碱腐蚀、成品不因侵蚀而影响强度。
7.抗菌性。制品具拔水性,不发霉,并能隔离存在液体内细菌及虫类的侵蚀,不霉蛀。
8.物性佳。由聚丙烯纺丝直接铺成网热粘结而成,制品强度较一般短纤产品为佳,强度无方向性,纵横向强度相近。
9.在环保方面,使用的大多数无纺布的原材料是聚丙烯,而塑料袋的原材料是聚乙烯,两种物质虽然名字相似,但在化学结构上却相差甚远。聚乙烯的化学分子结构具有相当强的稳定性,极难降解,所以塑料袋需要300年才可分解完毕;而聚丙烯的化学结构不牢固,分子链很容易就可断裂,从而可以有效地降解,并且在无毒的形态中进入下一步环境循环,一个无纺布购物袋在90天内就可以彻底分解。而且无纺布购物袋可重复使用10次以上,废弃后对环境的污染度也只有塑料袋的10%。
缺点:
1.与纺织布相比强度和耐久性较差。
2.不能像其他布料一样清洗。
3.纤维按一定方向排列、所以容易从直角方向裂开等等。因此生产方法的改善主要放在防止分裂的改良上。
Non woven fabric, also known as non-woven fabric, needle punched cotton, needle punched non-woven fabric, etc., is produced from polyester fiber, polyester fiber (PET) material, and is made through needle punching technology. It can be made in different thicknesses, feel, hardness, etc. Non woven fabrics have the characteristics of moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxic and odorless, low price, and recyclability. Can be used in different industries, such as sound insulation, insulation, electric heating pads, masks, clothing, medical, filling materials, etc
Advantages:
1. Lightweight: Polypropylene resin is the main production raw material, with a specific gravity of only 0.9, which is only three-fifths that of cotton. It has fluffiness and a good feel.2. Soft: Made of fine fibers (2-3D), it is formed by lightweight hot melt bonding. The finished product has moderate softness and a comfortable feeling.
3. Water absorption and breathability: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water absorption performance. It is composed of 100% fibers and has porosity, good breathability, and is easy to keep the cloth surface dry and easy to wash.
4. It can purify the air and use the advantage of small pores to keep bacteria and viruses out.
5. Non toxic and non irritating: The product is produced using FDA compliant food grade raw materials, free from other chemical components, stable in performance, non-toxic, odorless, and non irritating to the skin.
6. Antibacterial and anti chemical agents: Polypropylene is a chemically inert substance that is not infested by insects and can isolate bacteria and insects present in the liquid; Antibacterial, alkaline corrosion, and the strength of the finished product is not affected by erosion.
7. Antibacterial properties. The product has water repellency, is not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.
8. Good physical properties. Made by directly laying polypropylene fibers into a mesh and hot bonding, the strength of the product is better than that of ordinary short fiber products, with no directional strength and similar longitudinal and transverse strength.
In terms of environmental protection, most of the raw materials used for non-woven fabrics are polypropylene, while the raw material for plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are very different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose completely; The chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can effectively degrade and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution level to the environment after disposal is only 10% of that of plastic bags.
Disadvantages:
Compared with textile fabrics, the strength and durability are poor.2. It cannot be cleaned like other fabrics.
3. The fibers are arranged in a certain direction, so they are easy to crack from a right angle, and so on. Therefore, the improvement of production methods is mainly focused on improving the prevention of splitting.

止水螺杆使用时的安装间距
我们知道止水螺杆普遍的操作方法是木模板或复合型模版时选用,止水螺杆这一在标准里〈施工工艺〉的规定是常见间隔在400~600,实际的间隔,应当看施工计划设计方案上的要求,由于有的的地区施工单位墙的薄厚非常后,这类状况下止水螺杆间隔就规定就大。实际间隔牵涉到止水螺杆的应用直径、框架柱的高宽比,再开展实际的测算就可以得到。
We know that the common operating method for water stop screws is to use wooden templates or composite templates. In the standard “Construction Technology”, the spacing for water stop screws is usually between 400 and 600. The actual spacing should depend on the requirements of the construction plan design scheme. Due to the extremely thin thickness of the construction unit wall in some areas, the spacing for water stop screws is specified to be large in such situations. The actual spacing involves the application diameter of the water stop screw and the aspect ratio of the frame column, which can be obtained by conducting actual calculations.
pvc管材安装使用方法
PVC管材的安装方法: 1,PVC管在与钢管连接的时候,要先将钢管的连接处擦胶水,将PVC管加热后变软不会烧焦,然后承插在钢管上做降温处理。 2,粘接的时候严禁沾到水,PVC管必须放平在沟内,接头24小时后开始回填,要将管道的四周填紧,接头部位大批量回填。 3,玻璃纤维固化剂配成的树脂溶液浸渍玻璃纤维布之后,均匀缠绕在管道的渗漏出然后固化形成玻璃钢。 4,套补粘接法主要是针对管道小孔和接头的渗漏,选用统一的口径管材将其纵向剖开,然后将管内和外表面打毛,涂胶后在漏水处贴紧。
Installation method of PVC pipes:
1. When connecting PVC pipes to steel pipes, the joints of the pipes should be rubbed with glue first, and the PVC pipes should be heated to become soft without burning. Then, they should be inserted onto the steel pipes for cooling treatment.
2. During bonding, it is strictly prohibited to touch water. PVC pipes must be placed flat in the trench, and backfilling should begin 24 hours after the joint. The surrounding areas of the pipeline should be filled tightly, and the joint parts should be backfilled in large quantities.
3. After the resin solution prepared with glass fiber curing agent is impregnated with glass fiber cloth, it is evenly wrapped around the leakage of the pipeline and then solidified to form fiberglass.
4. The patching and bonding method is mainly aimed at the leakage of small holes and joints in the pipeline. A unified caliber pipe material is selected to longitudinally cut it open, and then the inner and outer surfaces of the pipe are roughened. After applying glue, it is tightly adhered to the leaking area.
钢筋连接套筒和钢筋接头的使用安装方法

1、 Use and installation of steel bar connection sleeves and steel bar joints 1. Steel bars in place: Transport the steel bars that have passed the wire head inspection to the joint to be connected. 2. Joint tightening: Use a wrench or pipe wrench to tighten the joint. 3. Mark: Mark the joints that have been tightened and separate them from the area of the joints that have not been tightened. 4. Construction inspection: Quality inspection of joints after construction. 5. Bind other steel bars. The technology of processing steel bar joints requires a very cautious process, and we can compare it with other processing technologies. The technical process of steel bar joints is very cautious.
钢筋马镫是做什么用的?
一、提高施工质量 铁马凳的采用,对建筑施工来说,是一种施工技术,因产品为工厂标准化、规格化生产,故其质量比人工制作的马镫更为标准,更加控制板楼下层钢筋保护层的标准性,并有效控制了上下层钢筋的间距。而且通过支架的使用,便于工地施工管理的规范,减少施工随意性。 二、提高施工效率 与传统人工工地现场制作的马镫相比,铁马凳因产品轻巧,安装简便,易于定位,从而减小施工人员劳动强度,通过实际使用情况测算,平均提高现场钢筋施工效率20%左右,在加快了钢筋混凝土施工进度的同时降低了施工成本。并且减少了工地的焊接,有利于提高项目施工的安全性。 三、降低施工成本 铁马凳的使用不仅有效控制工地废料的产生(包括工人现场制作马镫的认为损耗),而且减少了工人现场加工量,节约了工地现场用电量,很大程度降低了生产成本。并且我公司的产品价格比施工现场所用废钢筋制作的铁马凳节约成本30%左右,比用成品钢筋制作的马镫节约成本50%左右,直接降低施工成本。
1、 The use of iron horse stools to improve construction quality is a construction technology for building construction. As the product is standardized and produced by the factory, its quality is more standardized than that of manually made stirrups, which better controls the standardization of the protective layer of the lower steel bars in the slab building and effectively controls the spacing between the upper and lower steel bars. Moreover, the use of brackets facilitates standardized construction management on the construction site and reduces the randomness of construction. 2、 Compared with traditional manual on-site production of stirrups, the iron horse stool reduces the labor intensity of construction personnel due to its lightweight, easy installation, and easy positioning. Based on actual usage, it increases the on-site steel bar construction efficiency by an average of about 20%, accelerating the progress of reinforced concrete construction and reducing construction costs. And it reduces welding on the construction site, which is beneficial for improving the safety of project construction. 3、 The use of iron horse stools to reduce construction costs not only effectively controls the generation of waste materials on the construction site (including the perceived loss of stirrups made by workers on site), but also reduces the on-site processing volume of workers, saves electricity consumption on the construction site, and greatly reduces production costs. And our company’s product price saves about 30% of the cost compared to the iron horse stool made of waste steel bars on the construction site, and about 50% of the cost compared to the stirrup made of finished steel bars, directly reducing construction costs.
