Naphthalene Sulfonate Formaldehyde (SNF)
(Na2SO4 ≤ 5%)


Description
SNF is a high concentrate naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. FDN contains no chloride. It conforms to the requirements of chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.

Applications
1. SNF is suitable to make autotrophic concrete, steam curing concrete, steel concrete, prestress concrete, etc.
2. SNF is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.
3. SNF can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. SNF 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.

Features and Benefits
1. Non-toxic, non-irritating and no corrosion to steel bars.
2. High water reducing rate: over 25%.
3. Strengthening ability.
4. Improving concrete durability and impermeability.
5. Appropriate setting time.
6. Low sodium sulfate content.
7. No crystallization in winter.
8. Good compatibility with various types of cement.

Uses and Dosages
It can be added during mix or after mix, while the latter approach is preferential.
Dosage normally ranges from 0.4% to 1.0% of the weight of cementitious material, while the recommended dosage is 0.5%.

Q:Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
First of all, you can not replace the insulation material insulation, and many products in the development process slowly with the time will reflect their own shortcomings, insulation board has now been recognized by the state, and Insulation putty is not able to achieve the quality of the real ability to quantify. Insulation board normal life can reach 20 years, up to 30 years, the life of insulation putty is also 20 years, high water resistance can reach 30 years. Insulation putty can not be too thick construction, too thick easy to crack off, large area with the visual plane effect is poor. And the insulation board in the thickness of the greater arbitrariness, the insulation board in the construction of Ji Ji reclamation killing the old ghost tame handmade foam can make a large area of ??the wall is more smooth, of course, relatively heat putty, the construction cost is higher. But the two are complementary in the building, a small area more difficult to build the edge of the construction site, available insulation putty, large selection of insulation board, of course, for some of the insulation requirements are not high can also use insulation putty. The insulation requirements of a little more choice of insulation board. Insulation putty can replace the mortar, the premise is not to do other work above the putty. I hope my answer will help you!
Q:I am referring to the amount of dry mortar that is not stirred
The middle of the foam board, both sides of the barbed wire grid Mostly used in furniture, electrical appliances <within the packaging, pad, in order to prevent damage in the process of handling finished products> 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
Q:What is good for roof waterproofing? Coil or waterproof paint ah?
Because the roof needs long-term sun and rain erosion, so we recommend the need for rigid waterproof + flexible waterproof combination of construction, that is, first brush a K11 waterproof slurry, and then do a protective layer of mortar waterproofing agent, so that can meet the roof Waterproof demand.
Q:Now what is the general use of indoor plaster material? Please advise, thank you
General plaster general plaster used by the material are lime mortar, cement mortar, cement mortar, polymer cement mortar, knife knife ash, paper lime, plaster gypsum, etc
Q:Brick and concrete structure and frame structure in the force system, the use of building materials and the scope of the three aspects of the difference. Thank you ~ ~ very anxious
Wind load transfer wall → foundation → foundation → crust Frame structure: gravity load transfer floor panel → secondary beam → frame beam → frame column → foundation → foundation → crust Wind load transfer wall → frame (assigned to frame column) → foundation → foundation → crust (Seismic level role with the same) masonry structure load-bearing materials for the block, cement mortar wall, concrete floor, foundation; frame structure load-bearing material for the reinforced concrete The scope of application varies according to the intensity of fortification in the area, the building height of the masonry structure is 21M or less, and the frame structure height is below 60M For details, see GB-2010 Code for Building Seismic Design
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:Is the polymer cracked mortar and polymer bonded mortar the same?
5 Pu silicon cement, high-quality quartz sand, add imported polymer cement with a variety of additives, the double-axis mixture without gravity particles are mixed with powder building materials Polymer bonded mortar is a high molecular polymer cement based prefabricated dry mix Has excellent adhesion, good enhanced anti-droop, water retention, water resistance, aging resistance and operability Construction is simple, non-toxic pollution For the inside, the external walls and ceiling insulation board paste; can also be used for paste tiles, gypsum board and so on
Q:It seems to see a piece of information is 30 tons of twitch 紶 陛 cough pile correction point hole bowl film once, I now do are mortar test block test, ask the master, it is best to check that is not the supervision Sick of more
You see the information that key is not a regulatory information, regulatory information authority Regulate the mandatory twitch 紶 陛 cough piles of the correct point of the hole inside the capsule case did not say that by tons to count, did not say that mortar raw materials to be sent to the inspection, the specification is based on the inspection batch
Q:Bathroom to do with the East Yuhong waterproof material, but also with waterproofing agent to do waterproof layer?
First, the East Rainbow is just a waterproof material brand, followed by different home improvement parts need to choose a different waterproof material, some suitable for rigid waterproof, such as kitchen and bathroom; some need to rigid combination such as roof or balcony. And your question did not ask very clearly, so bad answer.
Q:Construction site masonry mortar requirements M5 should be how to configure how the calculation is very urgent Thank you, ah
M5 mixed mortar weight ratio of water: cement: sand: mixed material = 320: 260: 1440: . unit: kg
