JOYFORCE Polyvinylalkohol Feines Pulver<\/p>\n

Als Zusatzstoff f\u00fcr Zement und M\u00f6rtel kann PVA die Haftung und Flie\u00dff\u00e4higkeit von Zement und M\u00f6rtel wirksam erh\u00f6hen, die Trocknungszeit der Zementoberfl\u00e4che verlangsamen, die Anpassungsf\u00e4higkeit der Beschichtung erh\u00f6hen und die Rissbildung der Zementgewebeoberfl\u00e4che verhindern. Es eignet sich f\u00fcr Wand- und Deckenverkleidungen sowie f\u00fcr die Verklebung von Fliesen, da es einfach aufzutragen ist und die gew\u00fcnschten Effekte erzielt.<\/p>\n

PVA kann auch als Klebstoff f\u00fcr die Herstellung von Platten verwendet werden, wie z. B. Gipskartonplatten, schalld\u00e4mpfende Platten usw., egal ob es sich um organische Fasern (Zuckerrohrbagasse, Holzsp\u00e4ne) oder anorganische Materialien handelt, sie k\u00f6nnen mit den hocheffizienten Haftungs- und Wasserbest\u00e4ndigkeitseigenschaften von PVA ausgestattet werden, um sie zu komprimieren und zu einer Platte zu verkleben. PVA kann auch gut f\u00fcr Beschichtungen verwendet werden. Eine w\u00e4ssrige PVA-L\u00f6sung wird durch Salzs\u00e4ure katalysiert und Formaldehyd wird kondensiert, um eine wasserbest\u00e4ndige PVA-Formalpolymerverbindung zu bilden, die weithin als Innen- und Au\u00dfenwandbeschichtungen, Finishing, Abdichtungen usw. von Geb\u00e4uden verwendet wird. PVA-Beschichtungen sind witterungsbest\u00e4ndig, wasserfest, quellen nicht auf, wenn sie Wasser ausgesetzt sind, verspr\u00f6den nicht, sind ungiftig und geschmacksneutral und haben den Vorteil eines niedrigen Preises. In diesem Bereich k\u00f6nnen die herk\u00f6mmlichen Sorten nur f\u00fcr die Herstellung von Formplatten verwendet werden. Im Bereich der Beschichtung wird PVA mit einem h\u00f6heren Polymerisationsgrad verwendet.<\/p>\n\n\n\n\n\n\n\n\n\n
