WOTAI HPMC for Gypsum Plaster

WOTAI, a professional factory and distributor provides HPMC for gypsum plaster. HPMC is the perfect additive to increase the tensile strength of your gypsum plaster and other building materials. It is an adhesion agent that tremendously improves flexural strength and bonding strength.

 

Gypsum plaster is also called POP. It’s white cementation produced by dehydrating mineral gypsum, partially or completely. It’s often added with decelerators or hardeners. Employed with water in a plastic state, it sets and hardens by the chemical reunification of gypsum and water. WOTAI’s high-quality HPMC products can help your gypsum plaster perform better.

 

  • Gypsum is a readily available raw material, not hard to find
  • Easy and accessible. Fast drying, reduces water consumption
  • Lower thermal conductivity, saving energy for heating or cooling

HPMC Manufacturer and Supplier - WOTAIchem

WOTAI Chemical is a professional and reliable HPMC manufacturer and supplier. We provide you with the highest quality of HPMC. For gypsum plaster as well as other applications. The construction industry is constantly using new materials to improve building products’ quality and overall performance. Gypsum plaster is one of the latest materials, which is now widely used. However, the most important factor is HPMC as the basis of gypsum plaster, especially in terms of stability and thickening.

HPMC has great water retention power. This prevents cracking and enhances the overall appearance of the plaster. It also improves surface uniformity, lubricity and adhesion when applied to wall putty and other construction areas. Beyond that, of course, if you want to increase the tensile strength of gypsum plaster, HPMC is the right option for you. It can act as an interfacial agent. In other words, it can improve the bending strength of gypsum and increase the bonding strength. All of the above factors make HPMC a necessary part of gypsum plaster that every construction worker must have.

Good Water Retention & Thickening Effect

It is well known that cement reacts with water and cracks form when it dries. Gypsum plaster added HPMC, with water retention and thickening effect. There are no cracks after the surface dries out.

Durable And Fire Resistance

Gypsum plaster is light and durable, which means that its use adds very little weight to the building. It ensures the frame is able to cope with natural disasters and maintain its shape over a long time. In addition, gypsum plaster is highly resistant to fire and can hold the fire for up to 3 hours.

FAQs

How does cellulose ether benefit gypsum-based wall surfaces?

Gypsum-based wall surfaces use plastered gypsum instead of traditional cementitious materials. They are used for plastering and leveling indoor walls and ceilings in buildings.

 

Plastered gypsum forms strong adhesion with various inorganic substrates. It can prevent issues with the wall surfaces. That includes hollowing, cracking, and detachment seen in traditional cement mortar layers.

 

Many factors affect the evaporation rate of moisture in gypsum-based products. That includes air temperature, humidity, wind speed, etc.

 

Excellent HPMC products can address moisture retention issues. It can help disperse within gypsum slurry. And envelop all solid particles to form a wetting film.

 

This film can release moisture over a considerable period. Facilitating hydration with inorganic binding materials. Thus, it ensures the bonding strength and compressive strength of the materials.

What is the thickness of gypsum plaster strength generally?

1/2 is a relatively common gypsum board thickness, in many residential decorations.

How much is gypsum plaster?

Gypsum plaster price is about 10 to 11 dollars per square foot. Gypsum is the main material. A lot of times you put a layer of plaster on top of cement plaster, and you get a smooth surface.

What exactly is gypsum plaster used for?

Gypsum is a mushy substance that becomes hard when it dries and is used to paint walls, ceilings, partitions, and other areas. Plaster plastering is an old building technique.

Is the gypsum plaster wall strong enough?

Gypsum plaster, though light in weight, is very durable, and the walls are tough and strong. Plaster plate has a wide range of uses, any form of decoration needs to be used.

How long will the gypsum plaster wall last?

Under normal circumstances, the expected service life of gypsum plaster is more than 50 years. Apart from that, gypsum’s unique fire-resistant help protect buildings or reduce damage in the event of a fire.

What are the ingredients of gypsum plaster glue?
Gypsum plaster glue primarily consists of construction gypsum powder, cellulose ethers, retarders, heavy calcium powder, and sand. For gypsum plaster glue additives, we recommend high-quality HPMC products like our WOTAIchem TP75000B and above.
Do you have specialized products for lightweight plastering gypsum mortar?

For the construction of lightweight plastering gypsum mortar, we offer specialized products that can achieve a coverage rate of 120-130% and increase air entrainment, resulting in improved sag resistance. If you have specific requirements, please feel free to contact us, and our experts will design a customized solution and provide direct product supply.

How can I improve the drying time of lightweight gypsum plaster applied on walls from the bucket?
To expedite drying time, you can adjust the formula and increase the dosage of cellulose fibers. During hot weather conditions in summer, consider adding at least 0.5 kg more of joint compound (spackling paste) to accelerate the drying process.
What laboratory parameters should be tested for gypsum mortar, lightweight plaster gypsum, and specialty dry powder mortar?
The essential laboratory indicators to test include flexural strength, adhesive strength, water retention, and rheological properties (high shear, medium shear, low shear curves), among others. However, the final selection should be based on the specific application requirements.
