♦️ولکانیزاسیون: پرمصرف‌ترین و معمول‌ترین عامل ولکانش، گوگرد می‌باشد که با اکثر لاستیک‌های سیرنشده وارد واکنش شده و تولید فراورده ولکانیده می‌کند. گوگرد به دو آرایش رومبیک و بی‌شکل وجود دارد. دو عنصر سلنیم و تلوریم نیز قادر هستند محصولات ولکانیده تولید کنند. سلنیم و تلوریم در جایی‌که مقاومت گرمایی عالی مورد نیاز است جایگزین گوگرد می‌شوند. این مواد زمان پخت (ولکانش) را کاهش داده و خواص فراورده را بهبود می‌بخشند. @materials_parspajouhaan

For example, the Cboe Volatility Index fell from its 2022 peak of 36, which it hit Monday, to around 30 on Friday, a sign of easing tensions. Meanwhile, while the price of WTI crude oil slipped from Sunday’s multiyear high $130 of barrel to $109 a pop. Markets have been expecting heavy restrictions on Russian oil, some of which the U.S. has already imposed, and that would reduce the global supply and bring about even more burdensome inflation. DFR Lab sent the image through Microsoft Azure's Face Verification program and found that it was "highly unlikely" that the person in the second photo was the same as the first woman. The fact-checker Logically AI also found the claim to be false. The woman, Olena Kurilo, was also captured in a video after the airstrike and shown to have the injuries. Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis."
