Just today! Middle Eastern guests’ most important holiday, remember to send your blessings
Today’s Eid al-Fitr is one of the three major religious festivals in Islam. It is a major holiday for Muslims all over the world.
The end of Ramadan is one of the three most important Islamic festivals, Eid al-Fitr.
Every year’s Eid al-Fitr day depends on the moon phase. Muslims follow the month to fast, see the month of Iftar, and see the new moon on the last day of Ramadan. If you see the next day if you break the fast, it is Eid al-Fitr. If you do not see the new moon, continue. Fasting, postponement of the festival, generally not more than 3 days.
This year’s Eid al-Fitr is expected to fall on June 15. However, due to different geographical locations in each country, time may vary slightly. (For example, Pakistani media reported that the UAE predicts that it will see the new moon on the night of June 14th, then on June 15th it will be Eid al-Fitr, but Pakistan’s side is very unlikely to see the new moon on the evening of the 14th. They are expected to break fast on June 16th, but they may also be consistent with other countries on June 15.
The timetables for specific countries’ holidays are as follows:
On Eid al-Fitr, Muslims generally get up very early and can eat something after praying early, symbolizing the end of Ramadan. Then go to the mosque and listen to the monks and the Qur’an. Then pray in the direction of Mecca. On this day, Muslims will visit relatives and friends, embrace each other’s greetings, have dinner, and restore contact between friends and relatives. There will also be some lively celebrations around the country.
The fire sleeve developing very well in the Middle East market. Hebei Zeal Fiberglass Materials Co., Ltd. will continue to vigorously develop overseas markets and actively expand the fire sleeve business.
Hebei Zeal Glass Fiber Products Co., Ltd. is specialized in the production and sales of glass fiber casing, fabrics and products, high silica fiber products, fire protection casing, high temperature casing, high temperature cloth, aluminum foil anti-radiation products, etc. It is the largest in China. , The strongest and most technologically advanced industrial fiberglass product manufacturing enterprise, China’s largest production and R & D base for high temperature fireproof sleeve.
The special high-temperature materials of Hebei Zirh’s synthesis determines that the high-temperature casing has many other similar materials that are difficult to be replaced: high temperature resistance, thermal insulation performance, flame retardant performance, electrical insulation performance, chemical stability performance, weather resistance aging Performance, cold-resistant, water-resistant, oil-resistant, ozone-resistant, voltage-resistant, arc-resistant, corona-resistant, etc., especially safety and environmental performance, is the best alternative to asbestos and other hazardous products.
In the smelting industry, the temperature of the medium in the electric furnace is extremely high and it is easy to form high-temperature splashes (as is the case in the welding industry). After cooling and solidifying, slag forms on pipes or cables, which can make the rubber of the outer layer of pipes or cables hardened, and eventually Embrittlement breaks. The damage to unprotected equipment and cables is achieved through multiple silicone-coated high-temperature bushings, which can achieve multiple safety protections. The maximum temperature resistance can be as high as 1300 degrees Celsius, which can effectively block high-temperature melting of molten iron, molten copper, and molten aluminum. Splatters prevent the surrounding cables and equipment from being damaged.
In high-temperature plants, the internal temperature of many pipes, valves or equipment is very high. If you do not cover protective materials, you may easily cause burns or heat loss. Exceptional high-temperature bushings have better thermal stability than other polymer materials, as well as resistance to irradiation and thermal insulation, preventing accidents, reducing energy consumption, and preventing the direct transfer of heat from the medium inside the pipeline to the surrounding environment. The temperature of the workshop is too high, saving the cost of cooling.
The high-temperature bushing products of Hebei Zeal are not only used as special materials in aerospace, cutting-edge technology and military technology departments for their excellent performance, but also used in various sectors of the national economy. Their application scope has been extended to: steel, automobiles, Shipbuilding, aerospace, metallurgy, electromechanical, petrochemical, chemical, military, defense, scientific research and other industries in the high-temperature areas. Heating area cables, fluid lines, rolling mill cables, tubing, sawing surrounding cables, generator sets, electrical voltage equipment, Large-scale construction, hydraulic systems, automotive wiring harness and exhaust pipe industries.
It is generally distinguished by different alkali metal oxide content.
E-glass fiber (E glass fiber) Alkali metal oxide content less than 0.05% Chemical stability, electrical insulation properties, good strength, good water resistance, mainly used as electrical insulation materials, glass fiber reinforced materials, etc.
Alkali glass fiber (C glass fiber) Alkali metal oxide content 11.5-12.5% high alkali content, can not be used as electrical insulation material, but its chemical stability and strength is still good. It is generally used for latex fabrics, woven fabric substrates, acidic filter fabrics, and window screening substrates. It can also be used as a glass reinforced plastic material that does not require strict electrical properties and strength. Lower cost and wider use
Why is alkali-free glass fiber water resistant?
The role of water and glass fiber is firstly to attack the alkali metal oxide on the surface of the glass fiber, and the water is alkaline. With the increase of time, the glass fiber and the lye continue to act until the silica skeleton is destroyed, so the alkali-free glass fiber The advantages emerged immediately.
Why alkali-resistant glass fiber has good acid resistance?
Acid and glass fiber surface metal oxides, metal oxides (Na2O, K2O) segregation, dissolved; acid and glass fiber in the role of silicate to generate silicic acid, silicic acid rapid polymerization and gel into a gel, a glass surface to form a A very thin layer of silicon oxide protective film, practice has shown that Na2O, K2O is conducive to the formation of this protective film.
What are the factors that affect the strength of FRP?
1.Effect of Fiber Diameter and Length on Tensile Strength The finer the diameter, the higher the tensile strength and the greater the length of the fiber, the lower the tensile strength.
2.Influence of Chemical Composition on Tensile Strength The higher the alkali content, the lower the strength. E-glass fibers have 20% higher tensile strength than alkali glass fibers. E-glass fiber molding temperature is high, the hardening speed is fast, the structure of the bond can be large sodium oxide, potassium oxide and other basic oxides to help the oxides, which mainly through the destruction of the glass framework, so that the structure is loose, so as to achieve the purpose of dissolution. The higher the content of sodium oxide and potassium oxide, the corresponding decrease in the strength of the glass fiber.
3.Effect of storage time on strength The strength of fiberglass after storage for a period of time will decrease – the aging of fibers. Reasons: Water and oxygen in the air eroded the fibers
4.The effect of the load time on the strength The strength of the glass fiber is especially noticeable when the ambient humidity is lowered with the increase of the applied load time. Reason: The moisture adsorbed in the micro-crack accelerates the micro crack propagation speed under the action of external forces.
Summary: E-glass fiber strength and water resistance and electrical insulation are better than the alkali glass fiber; but the alkali-resistant glass fiber has higher acid resistance and economic advantages than non-alkali glass fiber.
