Injection Molding Machine. : This machine is used specially for, |
| |
a] Heat stability test: Mass tone & Tint tone of pigments.
Limit: At maximum temp. DE should be less then 3 with dwell time 5 minutes. |
| |
b] STD v/s Sample comparison: Mass tone - shade, Opacity, Dispersion
: Tint tone - Strength |
| |
|
2] |
Two Roll Mill: We are using specially for PVC & PE test of pigments. |
| |
a] STD v/s Sample comparison: Mass tone - shade, Opacity, Dispersion
: Tint tone - Strength |
| |
b] Migration Test |
| |
c] Dispersability Test: in PVC tint tone after 5, 7 10 minutes. |
| |
|
3] |
Blow Film Extruder:
We are using specially for making LDPE film of MB / PDP/Flush pigment to check Dispersion. |
4] |
Hot Press: We are using specially for, |
| |
a] for migration test |
| |
b] Making one PVC sheet of STD v/s Sample comparison to check shade, opacity & dispersion |
| |
|
| 5] |
Kneader:
we are using kneader for making Pre Dispersed Pigment [PDP] & Flush pigments for various film & fiber application. |
| |

1] |
Horizontal Mill we are using for, |
| |
A] Making aqueous Pigment concentration
|
| |
|
a] to check Shade, strength , opacity in mass & tint tone |
| |
|
b] To check viscosity, loading capacity, disperability of pigment |
| |
|
2] |
Red Devil {Vibro Shaker} it is used for making |
| |
a] Aqueous concentration |
| |
b] Solvent base paint |
| |
c] Flexo, Gravure, N.C. ink) |
| |
|
3] |
Muller: With hagmann gauge, it is used to test pigment as preliminary test. |
| |
a] new STD from overseas buyer,
|
| |
b] New product development(R & D)
|
| |
c] Each days production samples in three stages (P/S = Process sample, P/C= Press cake, Pul =
Pulverize sample: in some pigments we check roasted samples) |
| |
We used Muller coz it gives fast results to take fast decision .On the basis of muller results against std, we reject the sample or test the sample for final application (paint/plastic/ink). We can also check particle size & dispersability of pigment |
| |
|
4] |
Triple Roll Mill Used for Off Set Ink test. |
5] |
Autometic Applicatior (2 set): Used for making draw downs (STD v/s sample) of different applications, like Muller,
W.B.Paint, Alkyd paint, Gravure ink, flexo ink, N.C.Ink, off set ink, etc.) |
6] |
Hagmann gauge |
| |
Used to check Particle size of pigment using Muller mass paste & off set ink mass tone paste. |
| |
|
| Parameter test: |
| |
•Conductivity test : Conductivity meter
Seive residue : equipments : 325 mesh sieve, glass beaker , soft hair brush
• Oil absorption : equipments : glass beaker , knife(specula) , glass plate
