Product Description:

Naphthalene Sulfonate Formaldehyde (PNS)
(Na2SO4 ≤18%)


Description
PNS, a high range water reducer with no air entraining component, is also named as Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.

Application
1. PNS is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement.
2. PNS is applicable in areas with the daily lowest temperature of 0
and for making concrete which requires high fluidity, high strength or steam curing.
3. PNS can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. PNS can be used as a raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.
5. PNS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

The specific brand of words to distinguish your local material.
Q:Do the wall waterproofing can be directly on the brick brush on a layer of waterproof material on it
Can be ah, but in general are rafting spoiled slander diarrhea oblique riveting is done on the concrete, in fact, there are some tiles waterproof role, the late seepage of the words will be outside the brush waterproof paint, are generally used transparent glue, recommended Dragon wall waterproof transparent plastic, before the seepage used to the past few years will not change color, does not affect the decorative effect.
Q:Paste the culture of stone mortar into the construction site after the need to do material re-examination?
It is best to communicate with supervisors After all, the final data check is the quality supervision station inspection If the supervisor does not give advice Personal recommended mortar test block to send A mortar test block to check the cost is very cheap, and secondly to do a little bit of information always no harm
Q:Inorganic active wall insulation materials and building insulation mortar What is the difference
Fire performance, thermal conductivity of the construction process is not the same!
Q:Wall whitewash with 114 mixed mortar, no lime cream can be used to replace what other materials
It is recommended that you choose the product of Dongfang Yuhong Spraying Polyurea Supporting Material Rainbow PUP-261 Epoxy Primer is made of epoxy resin, curing agent, thinner and additives and other components for a concrete base Closed primer
Q:Whether the mortar waterproofing agent needs to be sampled for inspection
need According to the specification, the admixture of the approach must have the certificate and the product instruction manual, and then need qualified laboratories according to the proportion of the manual, the trial test, the performance is qualified before allowing the use of construction
Q:What are the general types of waterproof materials, the number of years of use?
Waterproof material is divided into the first category from the above, there is a flexible waterproof material and rigid waterproof material 1. Flexible waterproof material is divided into waterproof membrane waterproof coating sealing material 2. Rigid waterproof material is roughly divided into silicone waterproof material fatty acids Waterproof material is also commonly used in the waterproof membrane SBS, APP, TPO, waterproof coating is also divided into K11 general type, K11 flexible type, JS, rigid waterproofing is the most common mortar waterproofing agent The This is a lot of factors related to, such as whether the standard construction, the thickness of the waterproof layer, waterproof layer of the latter part of the protection, but one thing is certain is the mortar waterproofing agent Water resistance is relatively long for waterproofing materials.
Q:Basement wall wipe 20 thick PG waterproof mortar, what is "PG waterproof mortar"?
Type: the market used in the construction industry in the species is still relatively rich, generally according to its production process in the addition of the chemical composition of the different waterproofing agent, the market can be divided into the following four categories: 1 , Chloride metal salt waterproofing agent;
Q:Why brick-based project man-made masonry mortar can not modify the market price
Masonry mortar is made of cement, sand, lime, water by a certain percentage of mixed for the masonry works of building materials, the main role is to bond masonry materials The mortar made by mixing the above four materials is called mixed mortar, and the mortar mixed with cement, sand and water is called cement mortar Some city mortar for the commercial mortar, in the factory mix, then there is only one finished product price Pricing software default is no material ratio analysis, you can directly adjust the market price
Q:Sticky benzene board with mortar for each square about how many kilograms ah?
The middle of the foam board, both sides of the barbed wire grid Mostly used in furniture, electrical appliances inside and outside the building from the role of insulation EPS board (also known as benzene board) is made of polystyrene board abbreviation It is made of raw material through pre-hair, ripening, molding, drying and cutting It can be made into different density, different shapes of foam products, but also can produce a variety of different thickness of the foam sheet Widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields Can also be used to display the venue, merchandise cabinets, advertising signs and toys manufacturing bonded mortar with high quality modified special cement and a variety of polymer materials, packing by a unique combination of technology, good water retention, paste the high strength, construction is not falling Has excellent weather resistance, impact resistance and crack resistance Mainly used for polystyrene board and rock wool board, extruded board and other insulation board wall, wall and ceiling bonding
