BIGGER SIZE , MORE AREA MAKE BIGGER AIR FLOW

The Juntai DISC has A larger area, can with stand more pressure, and has A service life of 5-8 years

THE THICKER DISC EDGE, THE MORE STABLE , THE LONGER LIFE

1、Juntai Disc Diffuser is much thicker on the edge than others

2、Juntai disc diffuser cover thickness is 1.16cm, 0.31cm more than its counterparts.

3、The surface of Juntai Disc diffuser is more glossy, smooth without any black dot on it, we use high quality machine and make the material more plasticized, then the disc can be stronger , tough and resilience which guarantee the disc longer life.

HIGHER, LONGER SUPPORT SCREW MOUTH MAKE THE INSTALL MORE EASY AND STABLE

Juntai Disc Diffuser:The overall height of the Juntai disc is 5.5CM, which is 1.5CM higher than the general disc diffuser, and our thread length is 2.62CM, which is 0.51CM higher than others, which can make the installation more compact and stable, and achieve the effect of not being damaged easily.

JUNTAI DISC HAS SOLID EIGHT-RIB SUPPORT

The 9 CM of 8 ribs long are 0.5 CM more than other disc diffusers, which can make the ABS support strong enough for long-term use and more solid.

THE HEAVIER, THE MORE STABLE, THE STRONGER AND LONGER LIFE

1、Juntai Disc is 22% more heavier than others

2、The weight of Juntai disc diffuser is 587g, which is 105g more than the same 10-inch disc diffuser in the same industry, about 22% of the mass, can be better stabilized and plasticized.

JUNTAI EXCELLENT SPECIAL PROVED EPDM FORMULA

1、Most of Disc and tube diffuser easy to Clogging when in use, and most engineer thought the clogging is A Physical Phenomenon,but in fact, it is a It Is A ChemicalPhenomenon .

2、So an excellent formula of the membrane make the disc longer life .

① The organic solvent substances in the sewage will form and extract the zinc salt active agent and accelerator in the EPDM Formula,As a result, the inner surface of the membrane pores is fouled and the pores are blocked.

② Zinc salt materials are also hydrophilic, and they are easy to agglomerate with inorganic particles such as calcium and magnesium in water under aerobic conditions.

SOLUTION

1、Excellent formula, oil-free formula, reduce the extraction of the rubber compound material by the sewage medium.

2、The oleylamine surfactant is introduced into the formula to increase the polarity of the inner hole surface of the membrane, and the purpose of reducing the adhesion of dirt has been achieved.

In order to make long life of the Disc diffuser, the most important is the good fomula of EPDM.

After 10 years development, Juntai design a very good formula which be 3 to 5 years longer life and lower resistant, high deformation resistance and elasticity

① Import High quality EDPM 8600 from ExxonMobil

② High quality Carbon which from Cabot made in USA

JUNTAI DISC DIFFUSER 4 IMPORTANT ADVANTAGES

1、BIMODAL MOLECULAR WEIGHT EPDM ORIGINAL GUM

Reduced Ventilation Resistance 20%：

Using EPDM with "bimodal" molecular weight distribution, EPDM with "bimodal" molecular weight distribution, and EPDM with controlled long-chain branching, EPDM has good tear resistance while having high strength and high resilience. Compared with similar products, the ventilation resistance is reduced by 20% when the thickness and aperture are the same.

2、UNIQUE MATERIAL ANTI-BLOCKING DESIGN

No risk of hole clogging for 8 years：

Optimize the material formula, reduce the extraction of the rubber compound material by the sewage medium, The introduction of hydrophobic materials in the formula increases the polarity of the membrane surface, and has always achieved the purpose of reducing the adhesion of dirt.

3、Platinum Hydrosilylation Reaction Sulfurization

Tear strength increased to above 35KN/m：

Cross-linking process, a multi-component catalyst is used to make the hydrogen-containing silyl double bond undergo hydrosilylation reaction in the presence of Pt, resulting in concentrated cross-linking and improving the cross-linking method. In this way, the vulcanized finished product is While maintaining its elasticity, its tearing performance is greatly improved, and the tearing strength is increased to more than 35KN/m.

4、OIL-FREE FORMULA DESIGN

5-year elastic decay rate < 20%：

The softener will affect the vulcanization and reduce the cross-linking efficiency. At the same time, the softener will enter the macromolecular gap, affecting the formation of cross-linking bonds and reducing the cross-linking density of the cross-linking network. Therefore, the compression deformation of the cross-rubbing compound increases. Oil-free formula is adopted, 5 Annual elastic decay rate<20%.

JUNTAI MEMBRANE ADVANTAGES：DEVELOPMENT OF MEMBRANE MATERIALS

HIGH REBOUND HIGH TEAR RESISTANC：

1、Exxon Molecular Weight "Bimodal" Distribution EPDM Original Gum

2、Double peroxide vulcanization crosslinking technology

3、DMS company controllable long chain branching technology EPDM

4、The peroxy system forms carbon- carbon crosslinks, which have short crosslinks, high rigidity, high stability,low compression set, and high resilience, but also have the disadvantages of low tear strength and elongation.

THE INCREASE IN STRENGTH MAKES IT POSSIBLE TO INCREASE THE NUMBER OF PORES PER UNIT AREA

1、Increase the number of holes to: 25-30 holes/cm² compare to 20 holes/cm² of other suppliers

2、Tube diffuser membrane, 32,000 holes/m,most other suppliers just only 28000 holes

3、The pores are 30% smaller, and the ventilation resistance is also 20% smaller

4、Improves tear strength and elongation

In order to make the EPDM film have high elasticity and good tear resistance, we use EPDM with a "bimodal" molecular weight distribution.

EPDM with a "bimodal" molecular weight distribution has both high molecular weight polymer mechanical properties and EPDM with low molecular weight polymer processing performance, combined with EPDM with controlled long-chain branching, balances the properties of the polymer well. So that EPDM has good tear resistance while having high strength and high resilience.
