Uppfinnare: S. V. 0. Friberg. Inventor: S. V. 0. Friberg.
Prioritet begard frdn den 6 november 1940 (Finland). Priority requested from 6 November 1940 (Finland).
Metoden att ur agg'viteamnen framstalla limningsmedel har redan lange varit kand Den i regel stora tillgangen pa thmaterial har joke minst bidragit till den vidstrackta anvandning, som namnda limningsmedel erMint. I lander med mindre tillgang pa aggviteamnen, sadana som albumin och kasein, liar man i aratal forsilkt finna ett konkurrenskraftigt limningsmedel, dock utan att lyckas. The method of producing sizing agents from aggregates has long been known. In countries with less access to aggregates, such as albumin and casein, it has been difficult for years to find a competitive sizing agent, but without success.
Foreliggande uppfinning avser att ur just framstalla ett limningsmedel, som t. ex. vid limning av tra, faner eller dylikt giver ett tillfredsstallande resultat aven far de mest kravande anspra.k. Delta sker genom att j Osten forst pa i och for sig kant satt befrias frau aggviteamnen, t. ex. genom att jasten medelst baser extraheras och att jastens aggviteamnen ntfallas med syror. Genom att behandla dessa proteiner med syror eller baser, t. ex. attiksyra eller Ca (011)9, sura eller basiska salter t. ex. CH1C0ONa eller NHX1, vid olika temperaturer, beroende pa vilka kemikalier som anvants, erhaller man ett urn- ningsmedel, fullkomligt jamforbart med de basta albumin och kaseinlim. The present invention intends to produce from just a sizing agent, which e.g. when gluing wood, veneer or the like gives a satisfactory result even the most demanding claims. Delta takes place by freeing the cheese first on the edge itself from the aggvate teams, e.g. by extracting the yeast by means of bases and precipitating the yeast aggregates with acids. By treating these proteins with acids or bases, e.g. acetic acid or Ca (011) 9, acidic or basic salts e.g. CH1COONa or NHX1, at different temperatures, depending on the chemicals used, a urn- perfectly comparable to the best albumin and casein glue.
Exempel 1: 100 delar torr jast och 4 delar NaOH i vattenlosning sammanblandas och hallas c:a ett dygn vid 20-40° C, darefter foretages filtrering eller centrifugering. Filtratet surgores med attiksyra till pH 4,5, varvid aggvitan utfalles. Man tvattar fallningen med svagt attiksurt vatten, torkar densamma pa samma satt som kasein samt malar och siktar. Av detta torra protein blandas 60 kg med kg slackt kalk, 8 kg NaF och 100 liter vatten, varvid ett kallim erhalles. Example 1: 100 parts of dry yeast and 4 parts of NaOH in aqueous solution are mixed together and kept for about 24 hours at 20-40 ° C, after which filtration or centrifugation is carried out. The filtrate is acidified with acetic acid to pH 4.5, whereby the aggvitan precipitates. The precipitate is washed with weakly acidic water, dried in the same way as casein and ground and sieved. Of this dry protein is mixed 60 kg with kg of slaked lime, 8 kg of NaF and 100 liters of water, whereby a cold glue is obtained.
Exernpel 2: Jastprotein isoleras pa samma salt som i exempel 1 och 6,5 kg blandas med 6,kg blodalbumin, 1 kg slackt kalk, 0,5 1 ammoniak eller 0,4 kg 10 % NaOH samt 87 1 vatten, varvid ett kallim erhalles. Exernpel 2: Yeast protein is isolated on the same salt as in Example 1 and 6.5 kg is mixed with 6 kg of blood albumin, 1 kg of slaked lime, 0.5 l of ammonia or 0.4 kg of 10% NaOH and 87 l of water, whereby a cold glue is obtained.
Avensa kan man genom uldrygande av jastproteinerna med jast, albumin, kasein, soja, konsthartslimningsmedel och andra limningsmedel erhalla ett anvandbart limningsmedel. Vid samtliga dessa limningsmedel kunna naturligtvis vanliga utdrygningsmedel for lirnningsmedel komma till anvandning. Avensa kan vattenhallfastheten pa kant satt upphjalpas genom sma tillsatser av formalin- eller paraformaldehyd. Avensa can be obtained by wool-drying the yeast proteins with yeast, albumin, casein, soy, synthetic resin sizing agent and other sizing agents. With all of these sizing agents, of course, common excipients for sizing agents can be used. In addition, the water resistance on the edge can be improved by small additions of formalin or paraformaldehyde.
