Adhesive tape (duct tape, foil tape) is simply one of many many on a regular basis miscellaneous supplies a HVAC enterprise wants. A enterprise proprietor or buying supervisor might profit from the six easy steps beneath, which is able to enable you to make your best option when in search of a brand new provider of adhesive tape.
With a purpose to make the best selection, you actually need some private expertise with the product, so let me share mine with you to avoid wasting you some useful time. The assessments beneath don’t faux to be scientific, or a substitute for lab assessments, however they’ll educate you the fundamentals. Easy isn’t all the time silly…
1. Take a look at Adhesion for the perfect rule of thumb – actually! Stick your thumb to a distinct number of tapes samples. You’ll instantly really feel which of them do not stick effectively sufficient. Do not even think about these; simply throw them away, avoiding errors. Use the samples that do move this primary rule of thumb check and transfer on to the subsequent step.
2. Foil energy check. Make strips of tapes half inch by Three inch and stick them collectively in pairs (face to face, glue to attach). Attempt to pull every pair aside together with your fingers. See which aluminum foil will rip and which is able to maintain. Examine outcomes and select the strongest ones solely to proceed testing.
Three. Hearth retardant properties. From the remaining samples make some extra half inch by Three inch strips and mark them. Take away the protecting paper and light one of many samples with a match from one finish. Maintain the strip at a 45 o downwards angle. Do the identical with each strip, and you may dismiss those that burn with black smoke and don’t self-extinguish double sided tape heavy duty B087P6GRJ4.
four. Adhesion. By now you’ll most likely have 2-Three samples solely – simply as effectively as a result of this check is slightly difficult! Take a bit of sheet steel 1 inch by four -5 inches, and be sure that the steel is dry and clear on each side (no oil, no dust, no water). Maintain it or prop it up vertically (a chrome steel ruler will do). Put together pattern strips of half inch by Three inches once more. Break up the samples into combined pairs (after labelling them!) and stick half of every pattern to the steel plate (i.e. one pattern reverse one other on all sides of the steel plate, in order that half the tape is on the plate, and half is sticking 90 levels to the steel plate). Apply finger pressure to the samples to be sure that the great floor contact between tape and plate is achieved. Then, snatch the free ends of the samples you caught, and concurrently pull aside the tape samples. The pattern of tape with the higher adhesion will stay hooked up to the plate and the much less adhesive one will come off. Simply just be sure you stick the identical tape space (half ” x 1-1/2″) one towards one other, parallel, so the check is honest!
Now when you find yourself fairly conversant in the products, get to the paperwork to your closing comparability.
5. Examine technical knowledge. Ask your suppliers technical questions. The tape’s technical specs could also be in numerous codecs and primarily based on the completely different requirements. Some suppliers current the perfect out there knowledge, not the typical or minimal numbers. Analyse fastidiously – you’ve got private expertise now.
6. Verify costs and phrases, supply packaging. You’re good to go!
