Additives for plasterboard play a crucial role in enhancing the performance and properties of gypsum-based construction materials. These additives cater to various aspects, from improving the foaming characteristics to optimising fluidity and aiding in the grinding process of gypsum.
Low coalescence foaming agents are additives designed to generate stable and fine foam in plasterboard formulations. This type of foaming agent ensures uniform air distribution, contributing to enhanced insulation properties and reduced density in the plasterboard. It is particularly beneficial for achieving lightweight structures with improved thermal and acoustic characteristics.
Medium coalescence foaming agents serve as versatile additives in plasterboard applications. They provide a balanced compromise between stability and drainage in the foam structure, making them suitable for diverse construction requirements. This type of foaming agent is often chosen for applications where a moderate level of foam stability and drainage is desired.
High coalescence foaming agents are engineered for applications where prolonged foam stability is paramount. These additives create a robust and long-lasting foam structure in plasterboard, offering superior crack resistance and improved overall strength. High coalescence foaming agents are particularly beneficial in scenarios where extended processing times are required.
Fluidisers are additives that enhance the flow properties of gypsum-based formulations. By reducing friction between particles, fluidisers improve the workability of plasterboard mixtures, making them easier to handle and ensuring a smoother application process. This results in increased efficiency during construction and improved overall product quality.
Gypsum Grinding Aids are additives used during the milling process to enhance the efficiency of gypsum grinding. These aids improve the grindability of gypsum, leading to reduced energy consumption and finer particle size distribution. Gypsum grinding aids contribute to more efficient production processes, resulting in plasterboard with improved setting times and enhanced mechanical properties.
Incorporating these additives into plasterboard formulations allows for customisation, optimising various aspects of the material’s performance and contributing to the creation of high-quality, efficient, and durable construction materials.
Product and customer insights
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
