As there is a mega shortage of industrial units around my area I have had to settle for a place without a water supply. Therefore it is impossible for us to blast a screen with a pressure washer.
If I Use a dip tank for exposing the screen after burning the image is there any chemical i will need to put in the water for all the detail to come out nicely?
You don't want to use a dip tank for exposing. The dip tank is for stripping all the emulsion off of the screen. You can use a simple garden hose to washout an exposed screen...
"I have had to settle for a place without a water supply" ...... Therefore a hose can not be used. Any other suggestions as to what i can do?
Dipping the exposed screen into a dip tank of water will not clear out your screen. You need 1. PRESSURE, 2. WATER.
Without water supply, it'd be a tough thing to do...Not to be rude, but what were ya thinkin, it seems you knew before hand that you needed water. The only thing I can think is expose and washout screens at your house/apt, then bring it to your warehouse.
(Something to think about, you're also going to need water for washing other things such as your hands, tools, when reclaiming screens, etc.)
I had to go with this unit as after weeks of searching there was still no luck of finiding a unit with water supply.
I have however just had a break through.
I attached a hosepipe with a bear end to my preasure washer and dipped the bare end in a bucket of water. now the pressure washer pulls the water out of the bucket and shoots it out with enough pressure to expose my screens.
There is a water supply in the (shared) bathroom so I can fill the bucket up when needed. However, due to health and safety regulations, I cant have a hosepipe trailing through to my unit.
Option 1-
You can always buy a few industrial spray bottles at a Home Depot or Lowes and fill em up with water. After exposing wet both sides and let sit for a few minutes. Then spray them out....it takes longer and it does get tiresome, but it does work.
Option 2-
Purchase a recirculating washout sink. Initially you do need to fill it up with water, but there is no plumbing required. Their made for cleaning ink off of screens but I use mine for washing out the stencil.
