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.

Product Description: This cryogenic pulveriser uses liquid nitrogen as cooling medium. When crushed material is achieved at the brittle fractured state,it goes into mechanical pulverizing chamber and repeatedly impacts,collides,shears,mills by high speed rotation of blade and gear to reach the optimal crushing effect. The milled material has airflow grading machine to classify and collect. If the fineness of material does not meet the requirements,it will return silo to continue grinding. The liquid nitrogen mostly can be cyclic utilization. Working principle: Low temperature pulverizer system with liquid nitrogen as the cold source, the crushed material through cooling embrittlement at low temperature easy to smash after entering the pulverizer cavity through the high-speed rotation of the impeller, the material and the leaf tooth plate, comprehensive effect between the material and the material are repeated impact, shear, collision, friction and so on, to reach the crushing effect. The crushed material is classified and collected by air classifier, and the material which does not reach the fineness requirement is returned to the silo to continue to smash, and most of the cold air is returned to the material bin for recycling.

Redispersible polymer powder should be stored in cool and dry environment. It is recommended to use within 6 months, preferably be used as soon as possible in summer. Storage in high temperature and humidity conditions will increase the risk of caking. Opened containers should be used as soon as possible, if not, should be resealed to prevent ingress of moisture from the air. Redispersible polymer powder supplied in paper bags should not be stacked. Prolonged heavy pressure may cause caking. Storage under pressure should also be avoided.
