PVC给水管材管件是怎么制造的

PVC管在装修的时候，应用的非常的多。但是你对PVC管的生产工艺了解多少呢?一般的PVC管在生产的时候都要经过混合工艺;挤出工艺;定型工艺;牵引工艺。
下面详细介绍一下，每种工艺的过程。
混合工艺 PVC管在高速混合时，助剂渗入PVC树脂的空隙，使助剂在树脂中均匀分散，考虑到温度在1000C以上有利于物料中水蒸气蒸出，所以一般热混机的温度设在100~1200C。为了让助剂充分地与PVC微粒接触，减少填
充剂对助剂的吸附作用，应该在加入PVC树脂后即启动热混机，再按如下顺序投料：稳定剂、各种加工助剂、色料、填充剂。在实际生产中，大都是将原辅料全都投入后再启动热混机。这样下来。第一部完成。
挤出成型工艺。固体输送区的料筒温度一般控制在100~1400C 。若加料温度过低，使固体输送区延长，减少了塑化区和熔体输送区的长度，会引起塑化不良，影响产品质量。 第三。定型工艺 从机头口模挤出来的管状物
要经过冷却，使它变硬而定型。定型一般用定径套进行外径定型和内径定型两种方式。其中外径定型结构较为简单，操作方便，我国普遍采用。
牵引工艺。牵引装置的作用是给机头挤出的管材提供一定的牵引力和牵引速度，均匀地引出管材，并通过调节牵引速度调节管子的壁厚。牵引速度取决于挤出速度，一般牵引速度比挤出速度快1%~3%。
一般的PVC管都要经过这几步工艺的过程才能生产出来。

 PVC给水管材管件的连接安装说明

排水管件的连接安装正三通(正四通)装入立管与横管连接处，造成连接处形成水舌流，横支管水流不畅，排水系统气压波动大，卫生器具的水封容易被破坏，排水管道的内有毒有害气体侵入室内，造成环境污染。正确的做
法是在此应安装45°斜三通或顺水三通。2、排水立管与排水出户管连接管件的连接在一些高层建筑中，设计师往往在设计时需将出户管的管径放大一号，而施工时往往是在立管底部用两个与立管管径相同的45°弯头连接，再
在排出管上进行变径，往往容易在连接变径处形成气塞，造成管道堵塞，影响管道的排水。正确的做法是在立管底部用异径管放大后接弯头，且异径管用偏心异径管放大后接弯头，且异径管用偏心异径管，偏心侧在转弯的内

PP-R管道特点:

Jiangshan feiya plastic factory located in western zhejiang, is a set design, production, marketing and service as one of the pipes, pipe fittings enterprises, mainly produces PVC water supply pipe fittings pipe, drainage pipe, line pipe and accessories. Company introduced the latest technology and advanced production line, the detection means perfect, strong technical force, scientific management methods. Companies relying on solid technical strength and rich practical experience, the close relation between industry and enthusiasm to provide convenient service for the general customers, and to undertake the development of new products our customers tasks and technical advisory work.

The company since its inception products have been exported to all over the country, strong technical force, complete testing equipment, adhere to modern management mode, constantly develop new products, with high quality .

The main purpose of PVC electrical fittings pipe fittings:

pvc electrical fittings has excellent performance of strongstress-resistant, corrosion-resistant, anti-moth, flame retardant, insulation and so on. In the area of construction, it also has advantage of light weight, easy to cut, easy to bend, installation flexibility, quick construction and so on. Pvc retardant electrical casing has extensive use in concrete, floor or between walls as electrical conduit, underground pipe can also be used as general wiring conduit pipe Ming and telecommunications, network cabling pipe. PVC electrical accessories, electrical conduit has good bending performance. PVC electrical conduit is a kind of PVC as the main raw material, add some special resist, by extrusion of a pipe, commonly known as PVC electrical conduit retardant wire and pipe, tube and rodents. Retardant electrical casing production process is now usually carried out in strict accordance with JG3050-1998 production. Retardant electrical casing has models of Φ16 ~ Φ63mm, specifications are 205 (light), 305 (medium), 405 (heavy).
    Retardant electrical casing has a variety of performance characteristics, as an electrical conduit, its insulation performance is very good, with good anti-current breakdown voltage capability, generally able to withstand 25 kV voltage without breakdown, and it is no live dangerous. Retardant electrical casing also has a very good impact resistance, it can withstand the pressure, can be concealed within the concrete, no fear of the damage of pressure and shocks. Retardant electrical conduit also has good fireproof performance, because of high oxygen index, it is hard to make flame. If leave the flame, it will instantly self-extinguishing. Retardant electrical casing also has some moisture, acid corrosion properties, and will not cause corrosion when together with other materials.

Retardant electrical casing has a smell which pest does not like, thus avoiding the problem of pest damage bite. It has good flexible performance, with good bending resistance, we only need to insert a spring in a fire-retardant electrical casing, without heating, it can be blended with hand. Now fire-retardant electrical conduit can be used in the building or underground electrical installation, and its use is in extension.

PVC electrical accessories - Conduit Profile

Pvc electrical accessories is the abbreviation ofpolyvinylchloride,polyvinylchlorideproducts include common pipes, soles, toys, doors, stationery,polyvinylchloridepipe is an common products ofpolyvinylchloride. Althoughpolyvinylchloridehas features of stable, hard to be acid corrosion, high heat tolerant, its development are hindered by cost barriers, industrial policy barriers, scale barriers, financial barriers.

Vinyl chloride (PYC) resin as the main raw material, wire pipe products, because of its role in fire resistant,polyvinylchlorideis widely used in wire and fiber. Also often used to make gloves.

Polyvinylchloridecan be made from ethylene, chlorine and the catalyst.

PVC electrical conduit fittings are cheap, widely used. Polyvinyl chloride resin is white or pale yellow powder. Different additives can be added according to different use,Polyvinylchloridecan present different physical and mechanical properties. a variety of hard, soft and transparent products can be made if adding an appropriate amount of plasticizer in PVC resin.Convenience of PVC casing accessories in construction

PVC electrical accessories casing is very light, usually 1/10 of pressure tube, 1/6 of steel, and easy for transportation and installation. PVC casing construction is very convenient. Conduit consist of connectors, waterproof seals, brackets and other components. Reasonable design, easy construction, no need to pour concrete protective layer. Stent use modular connection, easy to install, and can greatly shorten the construction period, non-radioactive carcinogens, has significant economic and social benefits.

   Good corrosion resistance is a large characteristic of PVC casing, PVC casing material has excellent power acid, alkali, salt and other chemical solvents, corrosion, no case of oil cracking, can adapt to various soil and work environment. High strength, heat resistance, long service life. Compared to traditional forms of asbestos and cement , it with a flexible, high temperature, easy to break and aging, long life, non-radioactive contamination and other characteristics, its strength can replace steel, and overcome corrosion and avoid the damage caused by  high temperature of single-core cable.

Used as an electric pipe, of course, good insulating properties is indispensable.PVC casing itself retardant power, put out away from the fire, high volume resistivity, excellent insulation properties. The main ingredient of PVC power casing ispolyvinylchloride, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer is painted, the main ingredient in the middle ispolyvinylchloride, the lower is the adhesive-backed. It is now loved by the world, and is quite popular and is also widely used as a synthetic material.

Maintenance treatment of PVC electrical wire and pipe fittings

Maintenance of Pvc conduit fittings are diverse, and we can choose according to the actual situation.

    Due to external force causes small area damage, cracks of Pvc electrical conduit fittings, and if in the same physical properties, adhesion treatment is available. Roughen the damaged parts, cut the same diameter of the pipe, covering an area larger than the damaged parts, clean and roughen the inside of selected pipe, apply adhesive chip on damaged parts of and also the selected pipe, cover the repairing tube sheet to the damaged area, and fasten with a pipe clamp or wire. Pvc conduit can also use welding repair method, but be aware that welding parts is dry, meanwhile remove dust, oil and other oils on its surface, the adhesive must be cleaned before welding.

When need to replace damaged pipe, this damage part should be amputated, replace new pipe, specification overΦ160 can be use on-site hot socket repair method: lift up both ends of the pipeline which is sawed off , both sides make chamfered. The length of replace tube should be segment length plus insertion length on both ends, heat the replaced pipe on both ends,then insert into the original pipe, and put into the ditch, then water can go through after cooling.

Flange quick docking, amputate pvc pipes where need to be replaced break both ends, take four plate bearing joints, substitute tube section, the four bearing plate joints are set into for ends, make flange joint of the four ends. Plastic quick coupling connection, saw expansion or damaged parts, set into a loose flange and a rubber ring at both ends. lift one end of the broken pipe, set into flanged casing, pushed back flanged casing to an equal distance from both ends of the broken pipe, fasten the loose flange and flange casing with bolt.
