Features and functions of modified starch
Enhanced Bonding
Starch additives are known to enhance the bond between paper and gypsum. This leads to a stronger and more durable board. The enhanced bond improves the structural integrity of the board. A strong board with a longer lifespan is suitable for various applications.
Improved Water Resistance
Modified starches can be tailored to impart water-repellent properties to the gypsum board. This starch modification creates moisture-resistant boards. Water-resistant gypsum boards are ideal for high-humidity environments. These include commercial kitchens, bathrooms, and other such areas.
Increased Fire Resistance
Fire safety is a key concern in construction. Fortunately, modified starches can enhance the fire-resistant properties of gypsum board. This is achieved by improving the board's ability to resist heat and slow down flame spread. Increased fire resistance ensures occupant safety and property protection. This is done by minimizing potential fire damage.
Enhanced Workability
Modified starches improve the workability of the gypsum board slurry. This leads to easier and more efficient production processes. Enhanced workability reduces production costs and increases profit margins. It also results in a smoother board surface, which reduces finishing tasks.
Improved Dimensional Stability
Gypsum board starch modifications improve the dimensional stability of the final product. This minimizes problems like warping and shrinking. Improved dimensional stability ensures a consistent and high-quality product. This leads to increased customer satisfaction.
Eco-Friendly Additive
Modified starches are usually derived from renewable plant-based sources. This makes them more environmentally friendly compared to synthetic additives. Eco-friendly additives help manufacturers meet green building standards. This is in consideration of the environment.
Cost-Effective Solution
Modified starches provide a cost-effective alternative to other chemical additives used in gypsum board production. This helps to reduce overall production costs. Lower production costs can increase the profit margin for manufacturers. This makes their products more competitive in the market.
Types of modified starch
Gypsum board modified starch is widely known as a drywall or plasterboard. It is a building wallboard used to construct walls, ceilings, and partitions. Gypsum boards are of different types, and each serves a specific purpose. Below are the different types of gypsum board modified starch:
Regular Gypsum Board
The core of this board is gray, and its paper liner is pink. It is the most commonly used gypsum board. It is suitable for walls and ceilings in most interior spaces. It is ideal for areas that do not require special characteristics, such as fire resistance, moisture resistance, or sound attenuation.
Moisture-Resistant Gypsum Board
This board is green or blue. It is specifically designed for use in areas where moisture is present. Its core is modified starch and has water-repellent properties. Its paper liner is also treated to resist moisture. It is suitable for use in bathrooms, kitchens, and laundry rooms.
Fire-Retardant Gypsum Board
Its core is yellow. It is designed to improve building safety by slowing the spread of flames. It contains special additives and its paper liner has fire-retardant chemicals. This board is used in areas requiring fire-rated walls and ceilings, such as stairwells and elevator shafts.
Soundproof Gypsum Board
Its core is purple. It is designed to reduce sound transmission between rooms. It is heavier than regular gypsum board and has a special sound-dampening core. It is ideal for use in multi-family dwellings, hotels, and recording studios.
Paperless Gypsum Board
This board lacks paper liner. Instead, it has a mat made of fiberglass. It is moisture-resistant and used in areas with high humidity. It is more durable and less susceptible to mold growth than traditional gypsum board. It is suitable for commercial applications and areas with extreme conditions.
Specialty Gypsum Board
These boards are designed for specific applications. Examples include abuse-resistant boards, exterior-grade sheathing, and high-density boards. They offer enhanced durability, weather resistance, and structural integrity.
Scenarios of modified starch
Modified starch is used in gypsum boards to improve paper face adhesion, moisture resistance, and fire resistance. Modified starch-coated fiberglass offers additional strength and improved paper face adhesion. The following are some common applications of gypsum boards:
Commercial Construction Projects
Modified starch gypsum boards are widely used in office buildings, retail stores, hospitals, schools, and other commercial properties. Their fire resistance, smooth finish, and ease of installation make them ideal for constructing walls and ceilings in these settings.
Residential Construction and Renovation
Whether constructing new homes or renovating existing ones, modified starch gypsum boards are a popular choice for walls and ceilings in living rooms, bedrooms, kitchens, and bathrooms. Their affordability, durability, and aesthetic qualities make them suitable for residential applications.
High-Rise Buildings and Multifamily Dwellings
Gypsum boards are used in high-rise buildings and multifamily dwellings, such as apartments and condominiums. Their fire-resistant properties are crucial for ensuring occupant safety in these structures.
Commercial Interiors
Modified starch gypsum boards are commonly used in commercial interior spaces, such as hotels, restaurants, shopping malls, and airports. Their ability to create smooth, aesthetically pleasing surfaces while being durable and easy to maintain makes them ideal for these applications.
Specialized Facilities
Certain facilities require unique solutions, and modified starch gypsum boards provide that. For example, in healthcare facilities like hospitals and clinics, boards with enhanced antimicrobial properties can help reduce the spread of germs. In laboratories, boards with improved moisture resistance are essential.
Industrial Applications
Gypsum boards are not just for construction and residential use. They are also used in industrial applications, such as manufacturing facilities, warehouses, and workshops. Their durability, ease of maintenance, and fire-resistant properties make them suitable for these environments.
When choosing the modified starch to be used in the gypsum board manufacturing process, there are a few factors to consider. This includes:
Starch source
There are two main sources of starch: tuber and cereal. Tuber starches are more suitable for gypsum board due to their high gelatinization and viscosity. When purchasing starch for sale, it is important to verify the source by requesting certificates of analysis (COA) from the supplier.
Modification type
The buyer should determine the type of modification required for their gypsum board product. Physical modification, which includes modification through heat and acid, is usually preferred because it is cost effective. However, enzymatic and chemical modification types offer better results. Business owners should consult with their suppliers to determine the best modification type for their product.
Modification degree
The degree of modification affects the viscosity and gelatinization of the starch. Buyers should determine the viscosity and gelatinization requirements of their gypsum board. They should consult with their suppliers to determine the best degree of modification.
Starch purity
High purity starches offer better bond strength in gypsum board. Therefore, buyers should look for a starch with high purity.
Supplier expertise
Business owners should work with suppliers who have experience in the gypsum board industry. Such suppliers understand the buyers' needs and offer high quality products. They also offer technical support to their clients.
The Production Process of Modified Starch
Natural corn starch usually contains 10% to 12% moisture. In the modified starch factory, the corn starch is slightly dried and all passed through a 120-mesh sieve. Spray 0.3% hydrochloric acid alcohol solution as a catalyst, dilute the hydrochloric acid with an appropriate amount of anhydrous alcohol in advance, stir it evenly in a sealed mixer, and age for 2 hours to fully acidify the corn starch. The starch added with a hydrochloric acid alcohol solution is heated and acidified in an oil bath. The acidified starch in the oil bath is slowly heated, and the heating rate is controlled at 1°C/min. When the temperature reaches about 130°C, heat preservation and heating for 30 minutes, and then quickly cool to room temperature to obtain modified starch. The modified starch oil bath equipment is shown in the figure. The modified starch process is as follows:
Starch → Drying → Sieving → Acidification → Stirring → Aging → Heating → Modification → Cooling → Packaging → Modified starch
