Several ongoing studies have expanded this chemistry, generally through the chemical adjustments of this polymeric material. The chemical modification of PVC utilizing many materials as an active modifying agent is described In this particular get the job done. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and removing or dehydrochlorination. This standpoint addresses the principle PVC reactivity tendencies and offers an outline of PVC functionalization although analyzing the environmental implications of PVC through the prism of chemical recycling. Via extensive ongoing research, this chemistry has long been expanded, primarily in the chemical variations of this polymeric material. To enhance its Image-security Houses, broaden the applications of poly(vinyl chloride) (PVC), and look into PVC-relevant phenomena, numerous chemical modifications are released to PVC.
押出成形は、押出機のなかに溶融した原料を入れ、口金から押し出して成形する加工方法です。
Vid temperaturer upp till 60°C är styv PVC resistent mot de flesta oorganiska vätskor inklusive moderat koncentrerade syror samt alkali och icke-oxiderande saltlösningar i alla koncentrationer.

The contents of the reaction vessel are pressurized and continuously blended to maintain the suspension and guarantee a uniform particle size from the PVC resin. The reaction is exothermic and thus involves cooling. As the quantity is decreased in the course of the reaction (PVC is denser than VCM), water is constantly included towards the combination to take care of the suspension.[nine]

Furthermore, it has excellent electrical insulation properties, rendering it a suitable product for wiring and cable purposes.
PVC is manufactured from petroleum. The creation course of action also makes use of sodium chloride. Recycled PVC is broken down into powder or tiny chips Along with the impurities eliminated.

・耐衝撃性：他の五大汎用樹脂と比べて耐衝撃性に乏しい。特に低温環境だと衝撃値が低下する。
熱成形は、押出成形やカレンダー成形であらかじめ生産した板状の製品を加熱し、空気や気圧を利用して型の形に成形する加工方法です。
Major reason of the project is usually to enable the general public to find out some intriguing and significant specifics of chemical elements and lots of frequent resources. We know that the basic principles in the supplies science will help men and women to understand numerous frequent troubles.
The carbon-chlorine bonds inside the vinyl chloride units give PVC its distinct Qualities, including resistance to environmental aspects and electrical insulation.
