— od ove proizvodnje dobila bi se vrijednost bruto proizvoda godišnje oko 5.000 miliona dinara; — sa oko 1.500 miliona dinara dobiti, odnosno preko 1.000 miliona dinara za raspodjelu. Za iste investicije preko 3 puta veća vrijednost brutoprodukta, sa skoro 10 puta većom dobiti za raspodjelu. Investicije na 1 tonu proizvoda: kod celuloze 312.500 din kod lesonita 185.700 „ kod iverica 50.000 ,, Ovom upoređenju nije potreban komentar, jer se jasno vidi za koju vrstu proizvodnje treba koristiit postojeći drvni otpadak kao sirovinu. LITERATURA: Fran z Kollmann : Štand der Technik bei der Herstellung v. Holzspanplatten; Wilhel m Klauditz : Entwicklung, Štand und holzwirtschaftliche Bedeutung der Holzspanplattenherstellung; Klau s Steiner : Uber Verfahrenstechnik und Maschinen zur Herstellung hochwertiger Holzspanplatten; C. A. F r h. von Thielmann: Spanplatten — Praktikum. S u m m a r y The author reports on the production of chipboards abroad and about the possibilites of such activity in this country. He compares the production costs of chipboards in Germany with those to be expected arising from our own prospective industrial production. Whereupon he expounds in detail the technological processes of production of chipboards, and presents data on their physical and mechanical properties. He likewise reviews those foreign plants which produce chipboards along with their technical characters. In the sequence the author presents in tabulated form the investment and production costs, as well as the rentability of the various chipboard production processes. He eventually presents a comparison of the production costs per 1 ton of wood pulp, fibreboards and chipboards respectively, calculations showing the chipboards to possess the highest rentability. |
