Advantage of Using Chemically Strengthened Parabolic Mirror |
Disadvantage of Using Physically Tempered Parabolic Mirror |
| Mirror Parabolic Shapes |
- Does not Care
- Always Produce Flat Mirror
|
- Bend & Temper According to Each Design of Parabolic Shape
- Each Shape of Parabolic Mirror is Non-Interchangeable
|
| Thickness & Weight |
- 1mm or Even Thinner Mirror & Thus Lighter
|
- Usual 3.2mm & Comparatively Heavier
|
| Flexural Bending Strength |
- Excellent
- Flat Mirror Conforms to Any Shape of Sun Tracking Steel Structure
|
- Poor
- Must Be Physically Bend
|
| Impact Strength |
|
|
| Mechanical Strength |
|
|
| Scratch Proof |
|
|
| Optical Distortion |
- Absolutely Free of Optical Distortion
- Mirror Concentration Efficiency Is Not Reduced
|
- Inevitable Optical Distortion Due To Roller Hearth Design with Roll Forming Technology Or Press Bending Mould
- Inevitable Uncontrollable Bending Sag If Using Gravity Bending Technology with Ring Mould
- Mirror Concentration Efficiency Is Reduced
|
| Keep in Stock |
- Could be Possible
- Place Flat Mirror Order Once Mirror Sizes Are Design
- No Need To Know Parabolic Equation
- Conforms to Any Parabolic Steel Structure of Tracking System
|
- Impossible
- Place Order Only After Mirror Parabolic Equation Confirmed
|
| Transportation Cost |
- Very Lower
- Each Crate Holds Many More Area of Mirror Due to Thin & Flat
- Crate is Lighter Due to Light Mirror
|
- Expansive
- Each Crate Holds Lesser Area of Mirror Due to Thick & Curve
- Crate is Heavier Due to Thick Mirror
|
| Shape Stability |
- Steel Frame Structure of Tracking System May Distorted Day After Day
