همچنین محصولات فرعی وجود دارد که پروفیل‌های اکسترود شده بر پایهٔ پلی‌وینیل کلراید سخت (یو پی‌وی‌سی) با مقاومت ضربهٔ بالا و سطح خارجی سفید هستند و در ساخت در و پنجره‌هایی که در دیوارهٔ خارجی ساختمان به‌کار می‌روند، استفاده می‌گردند.
مخلوط‌کن‌های پودری: مخلوط کردن مواد مختلف توسط این مخلوط‌کننده‌ها انجام می‌گیرد. البته باید توجه کرد که در مخلوط کردن پایدارکننده‌ها، روان‌کننده‌ها، پیگمنت‌ها و… که باید مقدار آن‌ها نسبتاً کم باشد امکان ایجاد اشکالات عملی وجود دارد.
Health care: The Health care market uses PVC in many different health care gadgets such as blood baggage, tubing, and IV baggage. Its ability to be sterilized can make it suited to these programs.
Our Web-site follows all lawful needs to shield your privacy. Our Privateness Plan is really a authorized assertion that describes what sort of information regarding you we obtain, once you stop by our Web site.
About 50 % of the globe's PVC output ability is in China, Regardless of the closure of many Chinese PVC vegetation as a result of challenges complying with environmental laws and inadequate capacities of scale.
The molecular structure of PVC includes a lengthy-chain polymer with repeating vinyl chloride models. Every vinyl chloride device is made up of one carbon atom double-bonded to a chlorine atom and single-bonded to two hydrogen atoms.
PVC offers a set of exclusive properties that lead to its wide range of apps. One of the main qualities is its longevity and resistance to environmental stressors for example moisture, substances, and ultraviolet radiation.
Soon after hrs or choose to routine a simply call? No challenge. Mail us a message and we’ll soar ideal on it.
Flexible PVC is commonly Utilized in development as insulation on electrical wires or in flooring for residences, hospitals, schools, as well as other regions in which a sterile surroundings is necessary. Rigid PVC is usually Employed in design as pipe for plumbing and siding that is commonly known as
کارت‌های پی‌وی‌سی جنس مقاوم و قابل انعطافی دارند و به دلیل ماندگاری زیادی که دارند می‌توانند برای چاپ کارت‌های هوشمند و کارت بانکی و اعتباری و همچنین برای چاپ کارت پرسنلی و شناسایی مورد استفاده قرار بگیرند. از دیگر مزایای کارت‌های پی‌وی‌سی می‌توان به قابلیت ضدآب بودن آن اشاره کرد که در برابر رطوبت نیز مقاوم هستند؛ و همچنین پلاستیک مورد استفاده در تولید و چاپ کارت پی‌وی‌سی امکان بازیافت و استفادهٔ دوباره را دارد و به این ترتیب با استفاده از کارت‌های پی‌وی‌سی به جای کاغذ و مقوا از آسیب به محیط زیست هم پیشگیری می‌شود.

Poly(vinyl chloride) (PVC) has long been an interesting issue for polymer science study. Its properties are heightened by its inherent structural faults resulting from immediate manufacturing (by absolutely free-radical polymerization), which also trigger its thermal instability. Several of the fundamental limiting options of PVC happen to be instructed to become alleviated by enhanced chemistry during PVC synthesis, Together with using the two inorganic and natural and organic thermal stabilizers. The traits, characterization, modification, recycling, and a variety of applications of PVC are all examined On this paper together with the past and most up-to-date research discoveries. It has been instructed that a few of the basic restricting properties of PVC is often lessened by applying both of those inorganic and natural thermal stabilizers together with improved chemistry during PVC manufacture.
Future, the indicators get there at a شباك pvc cluster of cells known as the atrioventricular (AV) node, where they decelerate. This slight delay makes it possible for the ventricles to fill with blood. When the electrical alerts reach the ventricles, the chambers agreement and pump blood to the lungs or to the rest of the overall body.
Discovered inside the nineteenth century, this tough content has uncovered applications within a wide spectrum of industries resulting from its flexibility, chemical steadiness, and financial performance.
