Product Name

Name:Calcium Carbonate Nanopowder


Product Overview

Nano calcium carbonate is a new type of lightweight calcium carbonate products, due to the ultrafine calcium carbonate particles, fine and uniform particle size, narrow distribution, large specific surface area, surface activity and dispersion of good, high surface energy, so that in actual use embodies a lot of ordinary calcium carbonate materials do not have more excellent performance, more widely used. The main synthesis methods of calcium carbonate nanoparticles are carbonation method, precipitation method, etc. The produced calcium carbonate mainly exists in the form of calcite, and its particle size ranges from dozens to hundreds of nanometres. In the polymer melt, the agglomeration of the filler powder will adversely affect the performance of the material, so it is necessary to carry out surface modification of calcium carbonate nanoparticles before filling. Some commonly used surfactants are silane coupling agents, stearic acid, aluminates/titanates coupling agents, etc. These coupling agent molecules usually contain both hydrophilic and hydrophobic groups, which, combined with the groups on the surface of calcium carbonate, are able to reduce the surface energy of the calcium carbonate nanoparticles and improve their dispersion properties.

Product Features

1)Low water content, nearly neutral, and has good chemical stability, do not react with the curing glue in adhesives.

2)The large amount of addition can greatly reduce the cost of adhesive products (for example, the amount of silicone rubber sealant is more than 50%, and the amount of polyurethane adhesive is 20-30%).

3)With reinforcing effect, can improve the mechanical properties of the adhesive, reduce the shrinkage and thermal expansion coefficient, increase the thermal conductivity, improve heat resistance and adhesion force, improve the mechanical strength (hardness and compression strength) and corrosion resistance; can also lubricating the adhesive, improve the operation conditions, and improve the bonding performance.

4)Nano calcium carbonate has small particle size and large specific surface area, and has good solubility with the adhesive after certain surface treatment. It can be used as a thielectric agent in the adhesive system to adjust the viscosity of the adhesive, prevent the adhesive from sagging during the vertical surface construction, and improve its retention characteristics.

5)In the process of making color material, nano calcium carbonate is easy to color and will not affect the color of the product.

6)It has different modification effects in different adhesives, which can improve its rheological properties in PVC plastic sol; increased strength and wear resistance in silicone structural sealant; incremental reinforcement and heat resistance in hot melt adhesive; and thickening and adhesion in water-based adhesive.


Application Fields

1)Plastics industry: As a filler and enhancer, nano-calcium carbonate can improve the rigidity, toughness and heat resistance of plastic products, and improve their processing performance. For example, adding a small amount of light calcium carbonate to PVC products improves the tensile strength.

2)Rubber industry: Nano calcium carbonate used in high-performance tires, auto parts, bicycle tires and running shoes and other products, can increase the strength, rigidity and durability of the product.

3)Paper industry: used as a filler, nano calcium carbonate can improve the brightness, whiteness and flatness of paper, suitable for advanced packaging paper.

4)Patings and inks: Adding nano-calcium carbonate to coatings and inks gives the coating better gloss and durability, while reducing production costs.

5)Pharmaceutical industry: nano-calcium carbonate, as an important component and calcium source additive in the culture medium, is also used in the production of antibiotics, painkillers and gastric drugs.

Keeps you cool without being cold!
Size: Full/Queen(88"x88"), Color: White
Such a great comforter! The material is cooling but not cold—it’s the perfect balance. The fabric is super soft and feels really nice against the skin. The only downside is that it tends to slide off the bed easily, especially if paired with the Bedsure cooling fitted sheet since both are very smooth and slippery.

Perfect for anyone that gets too hot!
Size: Full/Queen(88"x88"), Color: Gray
I’ve purchased two of these now. One for me and one for my son. It really does stay cool!! It’s lightweight and comfortable. Highly recommend if you are a hot sleeper. My son is and he will be sitting playing games or watching tv and actually be able to have a blanket covering him and not cook himself. They have been washed and have held up just fine. Bedsure makes great products in general. My last few sheet/comforter sets have been from them. Give it a try.

Get your comfy on
Color: Black, Size: King, Color: Black, Size: King
This Bedsure King Mattress Topper - Viscose Made from Bamboo: This ultra-soft, thick, and fluffy pillow top mattress pad is made from bamboo and is 21 inches deep with a breathable, moisture-wicking design. It’s available in black and measures 78x80 inches. While it’s a great choice, it does take a bit of time to be able to use when you first receive it. First, you need to remove the packaging and then put it in the dryer on low fluff for 20 minutes. After that, you should lay it across your bed for 24 hours to allow it to expand fully. So, plan on not being able to use it for 2 days. However, following these instructions will ensure that you get the best ultra-soft thickness and the perfect fit for your bed, plus you’ll feel comfortable when you’re ready to sleep on it. This Bedsure King Mattress Topper is incredibly comfortable. You’ll have the best nights’ sleep of your life with it. The quality of this topper is exceptional. I washed it, dried it, and it still came out perfect. There were no clumps or bunching. It laid out perfectly on our king bed mattress. This thing feels amazing. I didn’t want to get out of bed. Being a coffee addict, I didn’t mind not having it first thing in the morning because it’s so soft. My husband even approved of this topper. I like how both of lying on it, I don’t feel him moving around. This Bedsure King Mattress Topper is not too soft that you sink in. It’s just right. It’s like a soft hug on your body, but not wrapped around you. After a few days of sleep on it, my back didn’t hurt. I was surprised. I also like how this topper helps protect and keep your mattress from wearing out quickly. It provides long-lasting stability to your mattress. This Bedsure King Mattress Topper is the perfect thickness. I love how my sheets still fit over this and my mattress with no problems. The topper stays put on my mattress also. I like the added elastic band for support keeping it in mattress. We just bought a new mattress and I wanted a topper to add more comfort so this was a perfect addition. Ive bought other Bedsure items for our condo, we rent out and guests always like those toppers. This the first time getting a single topper with no memory foam added separately. I have to say I like the added comfort this Bedsure King Mattress Topper - Viscose Made from Bamboo Ultra Soft Thick Fluffy Pillow Top Mattress Pad with 21 Inch Deep Pocket, Breathable, Moisture Wicking, Black, 78x80 Inch adds to our mattress top. It’s just the right added comfort. You can’t see the wording Bedsure through sheets either. I get do my stretches in bed, yoga and still able to do with no problems. The price is spot on for a nice quality mattress pad. Definitely highly recommend getting this for your mattress. You will be glad you did. It will last a long time.

A better topper from a company I trust
Color: Black, Size: Twin
I have a memory foam daybed that has seen better days. The top layer has started to shift from regular use, and I wanted something that would help hold it together. The Bedsure Twin Mattress Topper does exactly that and made a huge difference right away. This is a high quality, well constructed mattress pad. It fits securely over an extra thick mattress and stays in place. The corner bands under deep pockets are strong and keep everything aligned without slipping. The measurements are accurate. There are instructions to dry it, then leave it out to expand. There was no weird smell. What you see is exactly what you get, in a good way. The cushioning is even and comfortable, and the fabric feels thick and smooth. It adds structure while still improving comfort. It has a more premium look and function than expected, similar to what you would find in a Five-Star hotel. It feels expensive. I also appreciate that the color is not white. It looks cleaner over time and feels like a more practical choice. I have used several Bedsure products, and the quality has been consistent. I also like that it is a woman founded and owned brand, and they continue to improve their products.

adds a touch of comfort!
Color: Black, Size: Queen, Color: Black, Size: Queen
I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress. I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place. The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets. The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress. Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.
