PUR-sm\u00e4ltlim har ett grundl\u00e4ggande problem med dispersionsskyddslack.<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Dessa lim befinner sig i den s\u00e5 kallade \u201evaxfasen\u201c efter applicering och avkylning. I denna vaxfas \u00e4r vidh\u00e4ftningen till dispersionslackeringar endast svagt utvecklad.<\/p>

I den typiska processen f\u00f6r ett industriellt bokbinderi kan urlastningen fr\u00e5n klammervagnarna orsaka vibrationer p\u00e5 grund av sm\u00e5 fallh\u00f6jder p\u00e5 transportbanden eller stapeltrycket i treknivstrimaren leda till att omslaget lossnar fr\u00e5n PUR-rygglimmet.<\/p>

Limmet h\u00e4rdar som vanligt i efterhand och sidh\u00e5llbarheten \u00e4r h\u00f6g, typiskt f\u00f6r PUR, men resultatet blir en sorts \u201eoavsiktlig fri ryggbindning\u201c.<\/p>

Vid tillr\u00e4ckligt f\u00f6rsiktig hantering av de nybundna exemplaren beh\u00f6ver denna lossning inte n\u00f6dv\u00e4ndigtvis uppst\u00e5. N\u00e4r PUR-limmet v\u00e4l har reagerat vid befintlig kontakt kan omslaget inte l\u00e4ngre lossas utan materialbrott.<\/p>

Binds\u00e4ttning med omslag som lackats kan allts\u00e5 fungera, men medf\u00f6r alltid en risk f\u00f6r att det lossnar.\u00a0<\/p>

Rekommendation: Utsk\u00e4rningar p\u00e5 dispersionslackerade kuvert vid limytorna b\u00f6r generellt alltid g\u00f6ras enhetliga, \u00e4ven vid icke-reaktiva sm\u00e4ltlim.<\/p>

Detta g\u00e4ller f\u00f6r PUR-sm\u00e4ltlim i allm\u00e4nhet.<\/p>

Interessant nog uppvisar de \u201eicke-reaktiva sm\u00e4ltlimmen\u201c inte dessa avlossningar. F\u00f6r en produktion \u201emed icke-reaktiva sm\u00e4ltlim\u201c beh\u00f6ver ryggen p\u00e5 de dispersionslackade omslagen inte sparas ut.<\/p><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
