Vid temperaturer upp until 60°C är styv PVC resistent mot de flesta oorganiska vätskor inklusive moderat koncentrerade syror samt alkali och icke-oxiderande saltlösningar i alla koncentrationer.
Have in mind, PVC board just isn't significantly robust By itself, so it will need a foundation or support technique to prevent bending or breaking.
The contents in the response vessel are pressurized and frequently mixed to maintain the suspension and make certain a uniform particle dimensions of your PVC resin. The reaction is exothermic and thus needs ابواب وشبابيك pvc cooling. As the amount is minimized in the response (PVC is denser than VCM), h2o is continually additional for the combination to take care of the suspension.[nine]
