实验室PP阻燃通风管道注塑工艺及制作配比方法
Injection molding technology and production ratio of PP Flame Retardant ventilation pipe in laboratory
实验室PP阻燃通风管道材应水平堆放在平整的地上,应避免弯曲管材,堆置高度不得超过1.5m,管件应逐层码堆,不宜叠得过高。实验室PP阻燃通风管道管材和管件应放在通风******的库房或简易棚内,不得露天存放,防止阳光直射,注意防火安全,距离热源不得小于1m。搬运管材和管件时,应小心轻放,避免油污,严禁剧烈撞击,严禁与尖锐物品碰触和抛、摔、滚、拖。
PP flame-retardant ventilation pipe materials in the laboratory shall be stacked horizontally on the flat ground, bending pipes shall be avoided, and the stacking height shall not exceed 1.5m. Pipe fittings shall be stacked layer by layer, not too high. PP Flame Retardant ventilation pipes and pipe fittings in the laboratory shall be placed in a well ventilated warehouse or simple shed, and shall not be stored in the open air, to prevent direct sunlight, pay attention to fire safety, and shall not be less than 1 m away from the heat source. When handling pipes and pipe fittings, handle them with care to avoid oil contamination, and avoid violent impact. It is strictly prohibited to touch sharp objects and throw, fall, roll and drag them.
实验室PP阻燃通风管道
实验室PP阻燃通风管道是一种采用先进配方,以聚丙烯树脂为主要原料,加入适量的玻璃纤维丝和改性助剂,用******的成型工艺装置连续挤塑成型,内壁光滑,强度高,外壁采用工字钢原理带有垂直的加强筋的新型管材。适合软土质地区,广泛应用于市政工程雨水,污水排放;工业废水排放,小区排水工程;盐业输卤,渔业输水;矿井通风,排水工程;农林排灌,水利工程等。实验室PP阻燃通风管道材料新,产品结构合理,强度高,耐腐蚀;内壁光滑,流通量***,同流量使用口径小,不易结垢;重量轻,搬运安装方便,排管不需要做混凝土基础,施工快。实验室PP阻燃通风管道扩口承插连接“T型”橡胶圈密封,使管材的渗漏量达到了***,且扩口长度长,施工过程中不易脱落,保证了工程质量;注塑成型是利用热塑性塑料的热物理性质和加热可熔融,冷却又凝固的可逆性质,通过料斗把物料(通常为粒料)加入到外有加热、内装螺杆的料筒之内,物料在螺杆旋转作用下沿着螺槽输送并压实,同时在螺杆的剪切力和外传导热的作用下,塑化成为了均匀的熔体,聚集在螺杆头部,完成塑化阶段;然后,在螺杆的高压、高速推挤下,将熔体从喷嘴经过流道,注入到有冷却设施的模具型腔之内;再经过其一定的压力保持,完成注射阶段,***后经过冷却定型的阶段,便可以开启模具将制品***下。注塑是成型实验室PP阻燃通风管道件***主要的方法。
PP Flame Retardant ventilation pipe in the laboratory is a new type of pipe with advanced formula, polypropylene resin as the main raw material, proper amount of fiberglass and modified additives, continuous extrusion molding with unique molding process device, smooth inner wall, high strength, and I-steel principle with vertical stiffeners on the outer wall. Suitable for soft soil area, widely used in municipal engineering rainwater, sewage discharge, industrial wastewater discharge, community drainage engineering, salt industry brine transportation, fishery water transportation, mine ventilation, drainage engineering, agriculture and forestry drainage, water conservancy engineering, etc. The PP flame-retardant ventilation pipe material of the laboratory is new, the product structure is reasonable, the strength is high, corrosion-resistant; the inner wall is smooth, the flow volume is large, the same flow use diameter is small, not easy to scale; the weight is light, the handling and installation is convenient, the discharge pipe does not need to be made of concrete foundation, and the construction is fast. Laboratory PP flame-retardant ventilation pipe is sealed with "t" type rubber ring by flared socket connection, so that the leakage of pipe material reaches the minimum, and the flared length is long, which is not easy to fall off in the construction process, ensuring the engineering quality; injection molding is to use the thermophysical properties of thermoplastic plastics and the reversible properties of heating, melting, cooling and solidification, and to add materials (usually granular materials) to the outside through hopper In the barrel with heating and internal screw, the material is transported and compacted along the screw groove under the action of screw rotation. At the same time, under the action of screw shear force and external heat conduction, the plastic melt becomes uniform and gathers at the screw head to complete the plastic stage. Then, under the high-pressure and high-speed extrusion of screw, the melt is injected into the mold with cooling facilities from the nozzle through the flow channel In the mold cavity, after a certain pressure is maintained, the injection stage is completed, and finally the cooling and finalization stage is passed, then the mold can be opened to push the product down. Injection molding is the most important method of molding PP flame-retardant ventilation pipe in laboratory.
可成型实验室PP阻燃通风管道件或组成管件的部件包括热熔管件(对接、承插、鞍形)或长插口管件弯头,等径三通,异径三通,异径,法兰端头,端帽,鞍形管件。短接管件的中心部件弯头,等径三通,异径三通,异径,端帽,法兰端、塑料压缩型管件的塑料部件、电熔管件、阀门配件、管夹。注塑机的分类方法有多种,如按合模机构型式分,可分为液压式、液压机械式和电动机械式。注塑机主要由注射部件、合模部件、液压系统、机身、加热和冷却系统、电器控制系统以及加料装置等组成。与实验室PP阻燃通风管道件注塑质量和工艺直接相关的部分,是注塑部件中的塑化装置
The components of the molding laboratory PP flame-retardant ventilation pipe fittings or the components of the pipe fittings include hot-melt pipe fittings (butt joint, socket, saddle shaped) or long socket pipe fittings elbow, equal diameter tee, reducing tee, reducing, flange end, end cap, saddle shaped pipe fittings. Elbow, equal diameter tee, reducing tee, reducing, end cap, flange end, plastic parts of plastic compression type pipe fittings, electric fusion pipe fittings, valve fittings and pipe clamps of short-circuit pipe fittings. There are many kinds of classification methods of injection molding machine, such as according to the type of clamping mechanism, it can be divided into hydraulic, hydraulic mechanical and electric mechanical. Injection molding machine is mainly composed of injection parts, mold closing parts, hydraulic system, fuselage, heating and cooling system, electrical control system and feeding device. The part directly related to the injection quality and process of PP flame-retardant ventilation pipe in the laboratory is the plasticizing device in the injection parts
