1. Predstavenie testera hladkosti ST-01<\/h2>\n

ST-01 Tester hladkosti<\/strong>\u00a0je vysoko presn\u00e9 zariadenie na meranie hladkosti povrchu papiera a lepenky pod\u013ea Bekkovej met\u00f3dy. Pou\u017e\u00edva sa na stanovenie hladkosti papiera a lepenky.<\/p>\n

Hladkos\u0165<\/strong>\u00a0je metrika pou\u017e\u00edvan\u00e1 na hodnotenie stup\u0148a nerovnosti na povrchu papiera. Ud\u00e1va rovinnos\u0165 a hladkos\u0165 povrchu ka\u017ed\u00e9ho papiera. Vo v\u0161eobecnosti sa hladkos\u0165 vz\u0165ahuje na \u010das, ktor\u00fd je potrebn\u00fd na to, aby vzduch pre\u0161iel ur\u010dit\u00fdm mno\u017estvom medzi povrchom vzorky a kruhov\u00fdm povrchom za \u0161pecifick\u00fdch kontaktn\u00fdch podmienok a ur\u010dit\u00e9ho rozdielu tlakov, meran\u00fd v sekund\u00e1ch (s). \u010c\u00edm dlh\u0161\u00ed je tento \u010das, t\u00fdm lep\u0161ia je hladkos\u0165 papiera a t\u00fdm vy\u0161\u0161ie je hodnotenie hladkosti. Vo v\u0161eobecnosti plat\u00ed, \u017ee \u010d\u00edm vy\u0161\u0161ia je hladkos\u0165 papiera, t\u00fdm lep\u0161ia je kvalita tla\u010de. Preto si dosiahnutie uspokojivej kvality tla\u010de vy\u017eaduje hladkos\u0165 ako nevyhnutn\u00fa podmienku.<\/p>\n
