CPVC flower wreath filling/CPVC plum blossom ring filling

CPVCFlower wreath fillingIt is one of the conventional plastic fillers, and the flower wreath is made of PP, PVC, CPVC, PVDF materials, etc. The models include DN25/47/51/73/95/145, etc.

Dier Chemical Packing Co., Ltd., Pingxiang City, Jiangxi ProvinceproductionCPVC flower wreath fillingAlso known as the Taylor wreath, it is made up of12A large flat ring composed of a small circular ring arranged radially, similar to a circular sphere formed by winding the ends of a spiral spring together

DiEr Chemical Packing Co., LtdproductionCPVC flower wreath fillingHaving the followingFeatures: Low pressure, high energy, high mass transfer efficiency. Users can choose different materials such as polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF) and other plastics according to the operating conditions inside the tower (such as temperature, pressure, medium, etc.). It has the characteristics of high porosity, low pressure drop and mass transfer unit height, high flooding point, sufficient gas-liquid contact, low specific gravity, and high mass transfer efficiency. The usage temperature in various media is 60-150 degrees Celsius, and it is mostly used in gas scrubbing and purification towers.

1、 Product application

The CPVC plastic Taylor flower wreath produced by Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province has been applied in many projects such as Shenhua, Haijing, Baoshuo, Daguhua, Luzhou North, Sichuan Jinlu, Binhua, Dongying Chemical, Benxi Chlor alkali, Ruyuan Dongyangguang, Huaxiang Chemical, Yingkou Sanzheng, etc., and the application effect is very satisfactory. CPVC plastic plum blossom ring is a type of tower packing in China, which has properties that cannot be compared with other materials of packing. It is particularly suitable for the chlor alkali industry, which can reduce the labor intensity of workers, reduce the frequency of equipment maintenance, extend the service life of equipment, save investment and costs of equipment and materials, and has broad application prospects.

IIPerformance advantages of CPVC flower wreath filling material

CPVC chlorinated polyfloral ring filler material has the following properties:

(1) Good weather resistance and corrosion resistance: CPVC is not only resistant to ultraviolet radiation and atmospheric aging, but also to various acid and alkali media at room temperature. Even at 100 ℃, it is still resistant to media such as lactic acid and dilute alkali solution. It can be used as a solvent for amino sulfonic acid, sodium chlorate, sodium silicate, propylene glycol with a concentration greater than 25%, phenol with a concentration of 25%, chromic acid, butyric acid with a concentration of 3%, chloramine, fluorinated amine, etc. The order of chemical corrosion resistance of several plastics is: CPVC ≈ PVC>HDPE>polybutadiene>ABS. It has excellent thermal performance.

（2)CPVC, with superior thermal performance, can be used at temperatures 35-40 ℃ higher than PVC resin, and can reach temperatures above 100 ℃. Its Vicat softening temperature increases significantly with the increase of chlorine content, and its heat resistance is higher than other resins, making it an ideal heat-resistant plastic. The thermal deformation temperature order of several plastics is: CPVC>polybutadiene>ABS>HDPE>PVC.

（3)Good flame retardancy (up to UL94-V-0, 94-5V), good self extinguishing flame retardancy, and low smoke suppression.

3、 Product Overview

CPVC flower wreath filler, also known as plastic CPVC plum blossom ring or A-shaped plastic Taylor flower wreath, is a filling material formed by winding many circular rings into an ellipsoidal shape. A reinforcing rib is added in the middle to make it in an "A" shape, which greatly improves the compressive strength of the flower wreath (Type A considers the effective area of the overlapping shadows between the original flower wreath fillers to reach 40%, and solves the problem of overlapping parts by using Type A flower wreath filler, which enhances the strength of the circles between the fillers with a "one" support rod). At the same time, this packing material not only has the advantages of high flux and pressure reduction of general packing materials, but also has a high liquid holding capacity at the gaps of the packing material, which can prolong the residence time of the liquid in the tower, thereby increasing the contact time between the gas-liquid phases and improving the mass transfer efficiency of the packing material.

The product is mainly used in the ion exchange membrane caustic soda process, which requires the tower packing to have resistance toCorrosion caused by hot alkali, chlorine, and sub chlor alkali above 60~90 ℃. Generally, metal and ceramic fillers are not resistant to hot alkali corrosion, leading to blockage and poor separation efficiency of tower equipment, requiring frequent replacement. Ordinary plastic fillers are not resistant to corrosion from chlorine and hypochlorous acid. Most foreign countries use polytetrafluoroethylene and polyvinylidene fluoride plastic fillers, but the material cost is quite expensive and not suitable for injection molding.
