Abstract

Procedimento per produrre lana di vetro nella forma di piccole masse di forma irregolare che devono venire insufflate ad umido per formare un isolamento termico, il quale procedimento comprende gli stadi di formare vetro fuso in filamenti, raccogliere i filamenti di vetro come un complesso di lana di vetro su un trasportatore quando essi vengono spruzzati con un agente di trattamento che non ha proprietà legante ma che ha proprietà di respingere acqua e di tenuta di polvere, evaporare il contenuto di umidità dell'agente di trattamento alimentato al complesso di lana di vetro, tagliare a pezzetti il complesso di lana di vetro in piccole masse di forma irregolare con una macchina spezzettatrice di Garnett e trasferire le piccole masse ad uno stadio di confezionamento. Una miscela di paraffina liquida e silicone viene impiegata come agente di trattamento in combinazione con acqua e il deposito di paraffina liquida e di silicone dopo riscaldamento ed essiccamento viene regolato per situarsi entro un intervallo di 0,5 - 3,0 del peso dei filamenti di vetro.Method for producing glass wool in the form of small irregularly shaped masses which must be wet blown to form a thermal insulation, which method comprises the stages of forming molten glass in filaments, collecting the glass filaments as a complex of wool of glass on a conveyor when they are sprayed with a treatment agent which has no binding properties but which has the property of rejecting water and holding dust, evaporating the moisture content of the treatment agent fed to the glass wool complex, cutting into pieces the glass wool complex in small irregularly shaped masses with a Garnett chopping machine and transfer the small masses to a packaging stage. A mixture of liquid paraffin and silicone is used as a treatment agent in combination with water and the deposit of liquid paraffin and silicone after heating and drying is adjusted to lie within a range of 0.5 - 3.0 of the weight of the filaments of glass.
