Of course, if you need to restore or adhere PVC board You need to use conventional super glue or PVC cement. Could you paint expanded PVC sheet?(demonstrate/hide)
قالبگیری به روش تزریقی، اکستروژن و شکلدادن حرارتی نیز از روشهای دیگر هستند.
در سالهای اخیر پیویسی جایگزین مواد ساختمانسازی سنتی نظیر چوب، سیمان و سفال در بسیاری از مناطق شدهاست. با وجود ظهور یک مادهٔ ایدئال در ساختمانسازی همچنان نگرانی در رابطه با هزینهٔ پیویسی برای محیط زیست طبیعی و سلامتی انسان وجود دارد.

用途としては、上下水道管や波板などの建築資材や、家具のレザーなどに採用されており、私たちの身近なところでも、比較的見かけることが多いでしょう。
در مقابل حرارت و نور نسبتاً ناپایدار بوده و هیدروژن کلرید از آن خارج میشود. این ماده اثرات زیانبخشی روی خواص اشیاء دم دست (اجزای الکتریکی) علاوه بر اثرات فیزیولوژیکی بر جای میگذارد. پیویسی پلاستیکی سخت است که بهوسیلهٔ اضافه کردن روانکنندهها نرم و انعطافپذیر میشود. بیشترین مورد استفادهٔ آن فتالیت است.
Adaptable PVC is commonly used in development as insulation on electrical wires or in flooring for properties, hospitals, educational institutions, together with other parts wherever a sterile environment is necessary.

Poly(vinyl chloride) (PVC) continues to be a fascinating topic for polymer science analysis. Its qualities are heightened by its inherent structural faults resulting from direct production (by cost-free-radical polymerization), which also lead to its thermal instability. Several of the elemental restricting options of PVC are actually suggested to be alleviated by improved chemistry during PVC synthesis, in addition to the use of each inorganic and organic thermal stabilizers. The traits, characterization, modification, recycling, and numerous applications of PVC are all examined Within this paper along with the past and most recent study discoveries. It has been suggested that some of the fundamental limiting properties of PVC is usually lessened by applying both inorganic and organic thermal stabilizers in conjunction with enhanced chemistry all through PVC manufacture.
