This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites.

Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature.
Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts.

PREPARATION OF FURANE MORTAR :
Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life.
Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.

Product Name : Galvanized Angle

Surface : BA/2B/NO.1/NO.3/NO.4/8K/HL/2D/1D

Edge : Plain Mill

Standard : ASTM DIN GB JIS EN AISI

* Use of galvanized angle steel: widely used in power tower, communication tower, curtain wall materials, shelf construction, railway, highway protection, street lamp pole, marine components, building steel structure components, substation ancillary facilities, light industry, etc.
Hot dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold galvanizing coating mainly ensures full contact between zinc powder and steel through electrochemical principle, and generates electrode potential difference to prevent corrosion. It is used to immerse the derusted angle steel in the molten zinc at about 500 â?? to make the angle steel surface adhere to the zinc layer, so as to prevent corrosion. It is suitable for various strong acid, alkali fog and other strong corrosion environments.

Warehouse Storage

* Shandong Jintuo Metal Materials Co., Ltd is located in Liaocheng City, the capital of steel tubes. It is a large enterprise specializing in the sales of carbon steel, stainless steel, galvanized color coated products, and copper and aluminum.Our company adopts a flexible business approach and management mechanism to provide good services to customers, while also considering the interests of the owner and the project, in order to ensure the quality of the project

Packing and shipping

* Our products are exported to multiple overseas countries and regions such as Europe, America, South Asia, Southeast Asia, Africa, and Latin America, and have won the trust and support of customers with excellent quality and service.

* During the supply process, the company can timely use sufficient funds to adjust the production variety and model of the steel plant, ensuring the use needs during the peak construction period

Application field

* The company adheres to the corporate spirit of never being satisfied and striving to surpass, and continuously creates new brilliance with the new economic concept of continuous innovation. Reward guests and friends from all over the world with satisfactory service. Our company is willing to cooperate closely with friends from all walks of life at home and abroad, and work together to create a better tomorrow.
