Description
Przedmiotem wynalazku jest sposób obróbki warstwy powierzchniowej wstegi pilsni w procesie jej formowania, znajdujacy zastosowanie w pro¬ dukcji na mokro, zwlaszcza twardych plyt pilsnio¬ wych.The invention relates to a processing method the surface layer of the pilsni band in the process its formation, which is used in the pro¬ wet production, especially on hardboard out.
. Najbardziej charakterystyczna, dla produkcji plyt pilsniowych metoda mokra4 jest formowanie masy w postaci wodnej zawiesiny wlókien na ru¬ chomym sicie, na którym jest ona odwadniana w pierwszej fazie grawitacyjnie, w drugiej przez podcisnieniowe ssanie, a w trzeciecj poprzez me¬ chaniczne wyzymanie uformowanej wstegi pilsni.. The most characteristic for production of fibreboard wet method4 is forming the mass in the form of an aqueous suspension of fibers on the fleece the stiff sieve on which it is dewatered gravitationally in the first phase, through vacuum suction, and in the third through the me¬ chanic erasing of the formed pilsni band.
Wyciete z niej arkusze sa przetwarzane na plyty pilsniowe twarde, w operacji goracego prasowania.The sheets cut from it are processed into CDs hard felt, in hot pressing operation.
W opisanym sposobie równomiernosc wstegi za¬ lezy jedynie od prawidlowego wylewania masy na sito i od korekty -uksztaltowania warstwy powierz¬ chniowej przez mechaniczne ubijanie tej. warstwy w pierwszej fazie odwadniania.In the described process, the uniformity of the web is included it is only from the correct pouring of the mass onto sieve and for the correction of the formation of the surface layer chunk by mechanically tamping it. layers in the first phase of dehydration.
Stan taki powoduje, ze na skutek niezupelnie jednorodnej gestosci formowanej masy, wystepuje zróznicowanie grubosci wstegi po fazie podcisnie¬ niowego, odwadniania. Faza mechanicznego wyzy¬ mania wyrównuje wprawdzie grubcsc wstegi, lecz jednoczesnie w obszarach uprzednich zgrubien wystepuja wieksze zgeszczenia masy niz w obsza¬ rach wklesniec. Jest to powodem falistosci prawej powierzchni plyt, pojawiajacej sie przy rozpreza¬ niu sie materialu po goracym wyprascwaniu. Fa¬ listosc powierzchni jest znana wada plyt pilsnic- wych, szczególnie niekorzystna w procesach lakie¬ rowania. Stad plyty przeznaczone do lakierowania musza byc w zasadzie szlifowane. Podczas szlifo¬ wania nastepuje zdjecie najlepiej zasklepionej warstwy powierzchniowej, co znacznie utrudnia proces lakierowania.This state of affairs causes incomplete results homogeneous density of the molded mass occurs strip thickness variation after the vacuum phase drainage, drainage. The phase of mechanical exploitation the mania aligns the thick band, but simultaneously in the areas of previous thickening there are more compressions of the mass than in the area recesses. This is the cause of the right waviness the surface of the discs appearing when expanding not rubbing the material after hot ironing. Fa¬ surface leaf is a known defect of pilsnic boards particularly unfavorable in lacquer processes rowania. Hence the plates to be varnished they have to be ground in principle. During grinding wania, the best sealed photo follows surface layer, which makes it very difficult painting process.
Sposób wedlug wynalazku dotyczy procesu obróbki warstwy powierzchniowej wstegi pilsni w fazie jej formowania w stanie mokrym.The method according to the invention relates to a process treatment of the surface layer of the pilsni web in the wet state during its formation.
Istota sposobu polega, na prowadzeniu operacji frezowania warstwy powierzchniowej wstegi pilsni, miedzy operacjami podcisnieniowego odsysania wo¬ dy z wstegi i operacja mechanicznego wyzymania.The essence of the method consists in conducting the operation milling the surface layer of the pilsni band, between vacuum water suction operations ribbon dye and mechanical leaching operation.
Wprowadzona nowa operacja z duza dokladnoscia wyrównuje warstwe powierzchniowa wstegi. Fre¬ zowanie uporzadkowuje powierzchniowo wlókna wzdluz dlugosci plyty. Zastosowany sposób wedlug wynalazku, zapewnia otrzymywanie twardych plyt pilsniowych o bardzo gladkiej i równej powierz¬ chni i jedwabistym pclysku. Plyty takie mozna lakierowac bez potrzeby szlifowania, co w znacz¬ nym stopniu zmniejsza pracochlonnosc, a przede wszystkim podwyzsza jakosc wyrobu. > Przyklad. Przygotowana mase, stanowiaca wodna zawiesine wlókien, wylewa sie ze skrzyni wylewowej na ruchome sito, na którym pierwsza operacja jest odwadnianie grawitacyjne z jedno¬ czesnym mechanicznym wyrównywaniem warstwy 103 1533 powierzchniowej przez zewnetrzne jej ubijanie.Introduced new operation with great accuracy smoothes the surface layer of the web. Fre¬ organizes the surface of the fibers along the length of the disc. The method used as per of the invention, provides for the preparation of hard discs solid wood with a very smooth and even surface clean and silky. Such discs can be varnish without the need for sanding, which significantly to a small extent reduces the labor intensity, and above all for all it increases the quality of the product. > Example. Prepared mass, representing an aqueous suspension of fibers, poured out of the box pouring spout on a movable sieve, on which the first the operation is gravity drainage with one ¬ modern mechanical leveling of the layer 103 1533 by tamping it outside.
Nastepna operacja jest odwadnianie przez podcis¬ nieniowe odsysania wody.The next operation is drainage by vacuum water suction.
Kolejno wyrównuje sie dokladnie warstwe po¬ wierzchniowa przez jej frezowanie. Operacja fre¬ zowania uzyskuje sie zebranie nadmiaru masy i uporzadkowanie powierzchniowe wlókien wzdluz dlugosci wstegi. Tak uformowana wstege pilsni, poddaje sie mechanicznemu wyzymaniu, po czym nastepuje jej pociecie na arkusze, które nastepnie poddaje sie goracemu wyprasowaniu i otrzymuje S153 4 sie twarde plyty pilsniowe o równej i bardzo glad¬ kiej powierzchni, o jedwabistym polysku. s /9/0 — 130+20 egz.Subsequently, the half-layer is exactly smoothed out surface by milling it. Operation fre¬ In the process, the excess mass is collected and the arrangement of the surface of the fibers along the length of the ribbon. So formed pilsni ribbon, succumbs to mechanical quenching, and then She is then cut into sheets and then is hot ironed and replaced S153 4 hardboard with an even and very smooth surface smooth surface with a silky sheen. s / 9/0 - 130 + 20 copies
