(rPC) पुनर्चक्रित पॉलीकार्बोनेट

परिचय

रीसाइकल्ड पॉलीकार्बोनेट (rPC) एक उच्च-प्रदर्शन इंजीनियरिंग थर्मोप्लास्टिक है जो उपभोक्ता या औद्योगिक पॉलीकार्बोनेट अपशिष्ट को पुन: प्रयोज्य रेजिन, पेलेट्स, शीट्स या कंपाउंड्स में पुन: संसाधित करके बनाया जाता है। इसे महत्व दिया जाता है क्योंकि यह वर्जिन पॉलीकार्बोनेट से जुड़ी पारदर्शिता, प्रभाव शक्ति, आयामी स्थिरता और गर्मी प्रतिरोध को काफी हद तक बनाए रख सकता है जबकि जीवाश्म फीडस्टॉक्स की मांग को कम करता है और अपशिष्ट को घटाता है।

व्यवहार में, rPC सामग्री इंजीनियरिंग और परिपत्र-अर्थव्यवस्था रणनीति के चौराहे पर स्थित है: इसका उपयोग उच्च-मूल्य उपस्थिति या मांग वाली यांत्रिक प्रदर्शन की आवश्यकता वाले स्थानों पर किया जाता है, विशेष रूप से ऑटोमोटिव, इलेक्ट्रॉनिक्स, निर्माण और कुछ चिकित्सा तथा उपभोक्ता अनुप्रयोगों में। सामग्री कई रूपों में मौजूद है, जिनमें यांत्रिक रूप से रिसाइकल्ड ग्रेड, रासायनिक रूप से रिसाइकल्ड ग्रेड, अपारदर्शी या रंगीन कंपाउंड्स, और मिश्रित या प्रबलित फॉर्मूलेशन शामिल हैं जो प्रोसेसेबिलिटी, रंग, ज्वाला प्रतिरोध या अपक्षय प्रदर्शन में सुधार करते हैं।

rPC का विकास प्लास्टिक में बंद-लूप सामग्री पुनर्प्राप्ति, रासायनिक शुद्धिकरण और रिसाइकल्ड-कंटेंट तथा मास-बैलेंस योजनाओं जैसी प्रमाणन प्रणालियों की ओर व्यापक बदलाव को दर्शाता है। इसका भविष्य संग्रह गुणवत्ता, संदूषण नियंत्रण, रिसाइकल्ड कंटेंट पर नियामक दबाव और डी-कलराइजेशन, विघटन-precipitation रिसाइक्लिंग तथा एडिटिव पैकेजेस में निरंतर नवाचार द्वारा आकार लेगा जो लगभग-वर्जिन प्रदर्शन को बहाल करते हैं।
