1. Product name: AKD High Polymer Emulsifier 2. Product introduction: AKD high polymer emulsifier (instead of traditional cationic starch based) is a kind of cationic polymer product developed by our technical department,which is the initiative developed product in the market.It can not only emulsify AKD wax,but also proteched the AKD colloid dispersion and aid retention,it also can increase AKD sizing efficiency(2%-8%).It can get the high stability and better fixing effect AKD emulsion by mechanical stirring,in the meantime it greatly decrease AKD hygrolysis during storage and sizing process.Final AKD Emulsion shelf time is about 6 months which is longer than starch emulsified AKD emulsion.The final AKD Emulsion also has quicker curing effect. 3.Specification and Index: Item Specification Appearance light yellow viscosity liquid Solid content 40%min Viscosity,mPa.s,25�°C 2000-10000 mPa.s pH value 2-5 shelf life 6 months 4. Application: This Emulsifier greatly restricts the AKD hydrolysis and the migration aptitude.It can replace the starch based emulsifier and AKD curing agent,at the same time decrease the AKD WAX using quantity.The final AKD Emulsion by this high polymer emulsifier can realize 80% sizing effect after paper machine,and almost totally realize after rewinding,which can let the paper immediately get the good water resistance effect,so less surface sizing agent in size press can fulfill all the sizing requirement.For detail using method,please contact Greatland Chemicals Co.,Ltd. 5. Package and storage: It should be stored in the warehouse with dry and cool condition protected from frozen and sunlight directly. The temperature should be below 30 C.

ZHUOJUN redispersible polymer powders are produced by spray-drying special water-based emulsion and are mostly based on vinyl acetate-ethylene. They dissolve in water easily and quickly forms emulsion. Their chemical properties are the same as original emulsion completely. They have excellent flexibility in low temperature. The RDP powders can glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.
ZHUOJUN® redispersible polymer powders are free flowing white powders obtained by spray drying macromolecular copolymer dispersions under carefully defined conditions. They are mainly used improve cohesion, adhesion, flexibility and workability in constructions especially in dry-mix mortar. Typical Applications - Tile adhesives - Tile grout - Wall putty - External insulation and finish systems (EIFS) - Cement, lime or gypsum-based finished dry-mix mortar - Self-leveling flooring compounds - Repair mortars and crack fillers - Cement-based plasters - Gypsum fillers
The super-softening property of Redispersible Polymer Powder (RDP) can improve the flexibility of cement-based materials while guarantees other work performances. In this study, the influences of different mixing amounts of RDP on the compressive strength, flexural strength, flexural compression ratio and bonding strength of sulphoaluminate cement mortar were investigated. The microscopic morphological structure of RDP-modified sulphoaluminate cement mortar was also observed through SEM to analyse the influence mechanism. Results show that, with the mixing amount of 2.0%, the compressive strength of cement mortar was improved. This mixing amount also increased the 28d flexural strength to 8.21 MPa (5.0% improvement) and 14d bonding strength to 5.6 MPa (27.3% improvement). Addition of more RDP resulted in the increase in flexural compression ratio because the powder particles formed water-insoluble continuous polymer colloidal film in hardened paste. This film generated a network with cement dydration products throughout the paste, consequently promoting the flexibility of cement.

HEPES (4-hydroxyethyl piperazine ethanesulfonic acid) is a kind of hydrogen ion buffer with pH value ranging from 6.8 to 8.2. In the process of cell culture, we often need HEPES buffer. It is a kind of weak acid. In the open culture condition, if HEPES is added, it can prevent the increase of pH oxidation in the culture medium and maintain the pH at about 7.0. The final concentration of HEPES buffer was 10-50 mmol / L, which had no toxic effect on cells. Generally, 20 mmol / L HEPES can achieve buffering capacity. Since we often use it in cell culture medium, what are its advantages in cell culture medium? Most of the cells need pH 7.2-7.4, but the optimal pH for cell culture varies with different cell types. Fibroblasts prefer higher pH (7.4-7.7), while the subculture and transformation cell lines need acid pH (7.0-7.4). HEPES is a kind of nonionic amphoteric buffer, which has good buffer capacity in the range of pH 7.2-7.4. The advantage of this method is that it can maintain a relatively constant pH value in open culture or cell observation. Under this condition, the cover of the cell culture bottle should be tightened to prevent a small amount of carbonate needed in the culture medium from scattering into the air. HEPES produced by Desheng is white crystal powder, with main content of 99.50%, iron ion 5ppm, sulfate 0.05%, and heavy metal residue (PB) 10ppm. Can provide trial sample powder, self-made solution for testing.

PP is a nontoxic, odorless, odorless, tasteless, creamy, high crystalline polymer with a density of only 0.90 --" 0.91g /cm3, "one of the lightest plastics available. It is particularly stable for water, with a water absorption rate of 0.01% and a molecular weight of about 81,150,000. Good molding performance, but due to large shrinkage rate (1%~2.5%), thick wall products are easy to sag, it is difficult to meet the requirements for some parts with high dimensional precision, and the surface of products is glossy.
