The second glass fiber comprises, by mass, 10-20 parts of E-glass fiber, 10-20 parts of C-glass fiber, 10-20 parts of A-glass fiber, 10-20 parts of E-CR glass fiber, 11-18 parts of D-glass fiber, 10-19 parts of S-glass fiber, 12-18 parts of AR-glass fiber, 5-7 parts of sizing agent, 3-5 parts of modifier and 2-3 parts of additive, wherein the silicone sealant has excellent weather resistance, high and low temperature resistance, ultraviolet resistance and ageing resistance, is commonly used in the outdoor field of building curtain walls, doors and windows and sunlight rooms, has good bonding strength, chemical resistance and sealing property, is suitable for bonding and sealing of various outdoor building structures, has high bonding force, high initial bonding force and good weather resistance, is suitable for bonding of various outdoor materials, such as metal, ceramic, wood, modified polymer sealant has good flexibility and bonding property, is suitable for sealing joints of building outer walls, silicone sealant has good weather resistance and weather resistance, and weather resistance is also suitable for bonding of other silicone sealant with weather resistance, and weather resistance is also has good weather resistance and weather resistance.
The modifier is a silane coupling agent, the modifier is sodium lignin sulfate, the additive is tetratitanic acid, and the sizing agent is aqueous polyurethane.
During the mixing process, it is often necessary to add appropriate amounts of various auxiliary materials in order to ensure homogeneity and stability of the mixture. These auxiliary materials may include binders, thickeners or other modifiers, the addition of which can increase the viscosity, flowability of the mixture, promoting thorough mixing and reaction of the raw materials.
The whole raw material treatment process needs strict operation control and process flow management to ensure that the quality and the proportion of the mixed materials meet the requirements. Only through the careful design and the fine control of the raw material treatment, a high-quality raw material base can be provided for the subsequent production process, so that the performance and the quality of the final product are ensured to meet the standards and requirements.
In the second step, when the high-temperature melting furnace is used for carrying out high-temperature melting treatment on the mixed materials, the temperature of the high-temperature melting furnace is 1200-1600 ℃, and the high-temperature melting treatment time is 30-60 min.
In step two, melt drawing is a critical ring in the manufacture of glass fibers. First, the mixture after the first treatment is transferred to a high temperature melting furnace. The furnace plays a critical role here, the temperature of which is controlled between 1200-1600 degrees celsius, to ensure that the raw materials reach a sufficient melting temperature. This high temperature condition is necessary because the various materials are sufficiently fused to form a uniform glass liquid state only at high temperatures.
The high temperature melting process in a furnace typically takes 30min to 60min, which allows the raw materials to melt sufficiently and achieve the desired viscosity and fluidity. In this process, temperature control within the furnace is critical, as either too high or too low a temperature may result in the quality and stability of the glass liquid being affected.
Once the feedstock has reached an appropriate molten state, it can be transported to a wire drawing machine for drawing. The wire drawing machine is used for drawing the glass liquid material into fiber yarn, so that the transition from liquid state to solid state is realized. This process requires a high degree of precise control to ensure that the diameter and quality of the wire draw are satisfactory.
Finally, through this step, the glass fiber filaments are prepared and available for subsequent processing and production. This process requires not only precise control under high temperature conditions, but also highly specialized handling and management of equipment and raw materials to ensure maximization of product quality and production efficiency.
In the second step, when the glass liquid material is processed by the wire drawing machine, the processing temperature is 1100-1200 ℃, the wire drawing processing speed of the wire drawing machine is 10-12m/min, and the length of drawn fiber is 2400-3600 m.
In the second step of preparing glass fiber, the melting and drawing process is a key process link. Once the mixed material treated in the first step is sent into a high-temperature melting furnace, the raw material rapidly reaches a molten state in a high-temperature environment to form a glass liquid state with higher fluidity. This process requires a tight control of the furnace temperature, ensuring stability in the 1200-1600 degrees celsius range, to ensure that the feedstock is sufficiently melted without excessive thermalization or cooling.
Once the material has reached the proper molten state, the operation of the wire drawing machine follows. The drawing machine plays a critical role in this step and is capable of drawing glass liquid material into elongated glass filaments. In the process, the working temperature of the wire drawing machine is usually controlled between 1100 ℃ and 1200 ℃, and the temperature can ensure the fluidity of the glass material and prevent the quality degradation caused by overheating of the material.
In addition to temperature control, the drawing speed of the drawing machine is also very important. Generally, the wire drawing speed of the wire drawing machine is controlled within the range of 10-12m/min, so that the size and the diameter of the glass fiber can be ensured to meet the requirements, and the production efficiency and the quality stability are ensured.
In the drawing process, it is also necessary to control the fiber length of the drawn wire so as not to break the drawn wire as much as possible, and the fiber length is usually about 2400m to 3600 m. The control of this parameter directly influences the tensile strength and fineness of the glass filaments, which has an important influence on the properties and applications of the final product.
In the third step, before the spinning processing, the glass fiber bundles are firstly carded into single fibers with 200-300 pieces per bundle by a carding machine, then the single fibers are processed by one of mechanical net forming and air net forming, and after the net forming processing is finished, the subsequent processing procedures are carried out by a wire arranging machine and a twisting machine.
In the third step, the glass fiber obtained through the second step enters a weaving processing stage, which is a key step of converting the glass fiber into glass fiber gauze or glass fiber fabric. First, the glass fibers are treated by a carding machine to card the fiber bundles into 200-300 individual fibers per bundle. This process plays an important role in the finishing, separation and alignment of the fibers, helping to improve the uniformity of the fibers and the quality of the spun yarn.
Next, the filaments are subjected to a web forming process. There are two common methods of web formation, one is mechanical web formation and the other is air-laid. In mechanical reticulation, the individual fibers are interwoven and interlocked through a dedicated network of holes to form a stable network. Whereas in air-laying, the individual fibers are sprayed into a high velocity air stream, through which the fibers interweave with one another and deposit on a collecting surface to form a web.
After the completion of the web forming process, the processes of the wire arranging machine and the twisting machine follow. The wire arranging machine stretches the glass fiber which is formed into a net, so that the fiber is more average, and the strength and the stability of the fiber are enhanced. The twisting machine then twists the fibers, which process can be performed in different ways, such as S-twist, Z-twist, etc., as desired. The twisted fibers form an elongated fiberglass yarn.
Finally, glass fiber gauze or glass fiber fabric needs to be sized. Sizing agents are adhesives that increase strength, softness and durability by impregnating fiberglass gauze or fabrics. The sizing agent can be selected according to the specific application requirements, e.g. the sizing agent for the reinforcement material may be compatible with the resin in order to achieve a better adhesion effect when preparing the composite material.
In the fourth step, the preheating temperature is 160-180 ℃, the preheating time is 15-30min, the hardener is one of epoxy resin or acrylic acid, the reheating temperature is 180-230 ℃, and the reheating time is 5-20 min.
In the fourth step of manufacturing the environment-friendly glass fiber filter material, the hardening treatment is a crucial step. First, the glass fiber subjected to the textile sizing treatment in the third step is required to be subjected to a preheating treatment. The purpose of the preheating is to raise the temperature of the glass fibers so that they will more readily absorb and fix the hardener before receiving the applied hardener. The preheating temperature is 160-180 ℃, and the preheating time is usually 15-3 min, so that the glass fiber can reach an ideal preheating state.
After the preheating is completed, the surface of the glass fiber is coated with a hardener. Hardening agents are important materials that form a strong structure upon reheating, enhancing the stiffness and durability of the fiberglass product. The hardener can be selected from epoxy resin or acrylic acid, which has good adhesion and high temperature resistance, and can effectively cure the glass fiber product, and the following table shows the performance comparison of the glass fibers treated by different bonding components.
The bonding film forming agent is the most important component in the glass fiber impregnating compound, plays a decisive role in the processability of glass fibers and the performance of glass fiber reinforced plastic products, contains a large number of functional genes capable of reacting with glass and unsaturated resin, and can greatly improve the mechanical performance and the processability of the glass fibers.
After the hardening agent is coated, the glass fiber enters the heating equipment again for reheat heat treatment. The reheat temperature is typically between 180-230 degrees celsius and the reheat time is about 5 minutes to 20 minutes. This step is to sufficiently cure the hardener to ensure that it bonds well with the glass fibers, forming a strong fibrous structure.
Finally, after the reheat heating is finished, the glass fiber product is taken out of the heating equipment and naturally cooled to room temperature. Thus, the manufacturing process of the environment-friendly glass fiber filter material is completed. The processes are carefully designed, so that the quality and performance of the glass fiber product can meet the expected requirements, and the glass fiber product plays an important role in the field of environmental protection. The glass fiber filter material produced by the process steps has excellent filtering performance, corrosion resistance and high temperature resistance, can be widely applied to the fields of industrial waste gas treatment, water treatment and environmental protection, and makes positive contribution to improving the environmental quality.
