What is the role of redispersible polymer powders in dry mix mortars?

Redispersible polymer powder is a powder dispersion formed by spray drying of modified polymer EVA/VAE emulsion.


It has good dispersibility. It can still be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial lotion.

Therefore, in order to make it possible to produce high-quality dry mixed mortar and improve the performance of mortar, today we will talk about the applications of Redispersed polymer powder.

Redispersible polymer powder is an essential functional admixture for dry mix mortar, which can improve the high performance of mortar, the bonding strength of mortar and various substrates, the flexibility, tensile strength, compressive strength, bending strength, wear resistance, toughness, adhesion, water holding capacity and processability.

 

Masonry mortar and plaster

RDP provides a mortar with good impermeability, high water retention and frost resistance and high bonding strength, which can solve the problems such as cracking and penetration of mortar.

RDP KD 6033N as a neutral type, can be widely used in masonry mortar and plaster.

Self-leveling mortar

RDP in self-leveling mortar can improve the strength, cohesion, adhesion and wear resistance of the material. It can bring excellent rheology, constructability and best self sliding performance to the flooring.

If you are in the self-leveling mortar industry, KD 6111L can provide you the best solution. click here

 

Tile adhesive

As a tile caulking agent, RDP offers a good adhesion, good water retention, long opening time, flexibility, anti sagging, and good freeze-thaw resistance. It can bring a thin layer with high adhesion, high resistance to sliding and good construction workability.

RDP KD 6002N can perfectly substitute Vinnapas 5010N, be used in tile adhesive, wall putty, skim coat...

Waterproofing mortar

The RDP of waterproofing mortar enhance the bonding strength for all different substrates, reduce the dynamic modulus of elasticity, increase water retention and reduces water penetration. It provides a sealing system with hydrophobicity and waterproof functional requirements for products with high flexibility, high weather resistance and high waterproof technical requirements, and has a lasting effect.

In addition, redispersible polymer powder with hydrophobicity (like KD 6031H) can have good waterproofing mortar.

External wall insulation mortar; EIFS / ETICS system mortar

The RDP can enhance the cohesion of the mortar and the binding force on the insulation board, at the same time reduce energy consumption. 

The external thermal insulation mortar achieves the necessary workability, flexural strength and flexibility, which can make the mortar have good bonding strength with a series of thermal insulation materials and base course.

At the same time, it also improves the high impact resistance and surface crack resistance.

RDP KD 6044N as a more flexible type has higher adaptability to the temperature difference between seasons and days. At the same time, can against Vinnapas 8044N.

How Waterproof Is My Rain Coat: What Does 5000mm Mean?

图片
  If you are buying yourself a new   waterproof rain coat   and you're not too well versed in the ins and outs of modern day waterproofing technology, you may find yourself coming across a few rather confusing terms. What on earth does 5000mm mean? And 5000gsm? What's the difference? These are just a few of the questions that will be running through your mind.   Not to worry, our guide to waterproof technology is here to help. Number, Numbers, Numbers. But What Do They All Mean?   A waterproof garment is measured with two numbers. The first one measures how waterproof the  raincoat  is. This is measured in millimetres. You will see numbers from 2,000mm up to 8,000mm across our collection to describe to the consumer how dry the coat will keep you. But what does it mean? For example, if a coat were 5,000mm waterproof, a test is conducted where a long tube is placed over the fabric and the tube is then filled with water. 5,000mm or 5 metres (16.4 ft) is how far you could fill the

How does a Sweeping Robot Work?

图片
 A  sweeping robot  works by autonomously navigating and cleaning floors using a combination of sensors, motors, and advanced algorithms.  The Foundation of Sweeping Robots The concept of automated cleaning dates back to the late 20th century when the first robotic vacuums were introduced. These early models relied on basic bump-and-turn mechanisms to navigate. Over the years, advancements in  technology  have drastically improved the functionality and efficiency of these devices. The VIGGO sweeping robot stands at the forefront of this evolution, showcasing the latest innovations in robotic cleaning. How VIGGO Sweeping Robot Works Intelligent Navigation The VIGGO sweeping robot uses a combination of sensors to detect and avoid obstacles, ensuring smooth navigation around furniture and other objects. Infrared sensors help it to avoid collisions, and cliff sensors prevent it from falling down stairs. VIGGO’s advanced models utilize LIDAR technology to create detailed maps of their surro
