\u010co je epoxidov\u00e1 \u017eivica?<\/span><\/h2>\n

Najprv si mus\u00edte odpoveda\u0165 na ot\u00e1zku, \u010do je epoxidov\u00e1 \u017eivica. Z chemick\u00e9ho h\u013eadiska je to syntetick\u00fd polym\u00e9rny materi\u00e1l s charakteristickou \u0161trukt\u00farou pozost\u00e1vaj\u00facou z jedn\u00e9ho at\u00f3mu kysl\u00edka viazan\u00e9ho na dva at\u00f3my uhl\u00edka. Epoxidov\u00e9 \u017eivice nie s\u00fa nov\u00fdm vyn\u00e1lezom, preto\u017ee ich v roku 1934 patentovali nemeck\u00fd chemik a vyn\u00e1lezca Paul Schlack a \u0161vaj\u010diarsky chemik Pierre Castan. Epoxidov\u00e9 \u017eivice obsahuj\u00fa tekut\u00e9 zlo\u017eky a tvrdidl\u00e1, ktor\u00e9 po zmie\u0161an\u00ed chemicky reaguj\u00fa a vytv\u00e1raj\u00fa plasty s dobr\u00fdmi fyzik\u00e1lnymi vlastnos\u0165ami. Rozhodli sa pre univerz\u00e1lne vlastnosti epoxidov\u00fdch \u017eiv\u00edc. Tieto vlastnosti sa prejavuj\u00fa v tom, \u017ee po vytvrdnut\u00ed kvapalnej hmoty je kone\u010dn\u00fd polym\u00e9rny v\u00fdrobok netavite\u013en\u00fd a nerozpustn\u00fd. Epoxidov\u00e9 suspenzie sa m\u00f4\u017eu pou\u017e\u00edva\u0165 na laminovanie, lepenie a liatie, ako aj na impregn\u00e1ciu r\u00f4znych povrchov vr\u00e1tane dreva, skla, kovu a bet\u00f3nu. Zlo\u017eenie epoxidov\u00fdch \u017eiv\u00edc obsahuje okrem polyfenolov, zl\u00fa\u010den\u00edn rastlinn\u00e9ho p\u00f4vodu, aj \u0161peci\u00e1lne tvrdidlo. Do zmesi sa zvy\u010dajne prid\u00e1vaj\u00fa aj farbiv\u00e1, riedidl\u00e1 (napr\u00edklad ftal\u00e1ty) a plniv\u00e1 (napr\u00edklad meden\u00fd pr\u00e1\u0161ok, krieda, piesok a mastenec).<\/span><\/p>\n

Vlastnosti epoxidovej \u017eivice<\/span><\/h2>\n

Epoxidov\u00e9 \u017eivice sa vyzna\u010duj\u00fa vysokou odolnos\u0165ou proti oderu, po\u0161kriabaniu a n\u00e1razom. Vyzna\u010duj\u00fa sa tie\u017e pevnos\u0165ou v tlaku, pevnos\u0165ou v tlaku, pevnos\u0165ou v \u0165ahu a vysokou tvrdos\u0165ou. Medzi vlastnosti epoxidov\u00fdch \u017eiv\u00edc patr\u00ed aj nadpriemern\u00e1 odolnos\u0165 vo\u010di vlhkosti, teplu, olejom a tukom a niektor\u00fdm \u010fal\u0161\u00edm chemik\u00e1li\u00e1m, ako s\u00fa roztoky kysel\u00edn a sol\u00ed. S\u00fa menej intenz\u00edvne pri p\u00f4soben\u00ed chl\u00f3ru, metanolu alebo uh\u013eovod\u00edkov a pri vystaven\u00ed ultrafialov\u00e9mu alebo UV \u017eiareniu. V takom pr\u00edpade m\u00f4\u017ee povrch epoxidov\u00e9ho n\u00e1teru zo\u017eltn\u00fa\u0165 a na povrchu sa m\u00f4\u017ee vytvori\u0165 vrstva prachu.<\/span><\/p>\n

Pou\u017eitie epoxidovej \u017eivice<\/span><\/h2>\n

Epoxidov\u00e9 lepidlo m\u00e1 \u0161irok\u00e9 spektrum aplik\u00e1ci\u00ed, a preto sa tak \u013eahko pou\u017e\u00edva v mnoh\u00fdch priemyseln\u00fdch odvetviach. Je ide\u00e1lny na lepenie, hydroizol\u00e1ciu a podlahov\u00e9 krytiny. Pou\u017e\u00edva sa v zdravotn\u00fdch stredisk\u00e1ch, skladoch, priemyseln\u00fdch priestoroch, gar\u00e1\u017each a pivniciach v\u010faka svojej odolnosti, proti\u0161mykovej povrchovej \u00faprave a \u013eahko udr\u017eiavate\u013en\u00e9mu hygienick\u00e9mu povrchu.<\/span><\/p>\n

Skvele sa hod\u00ed na impregn\u00e1ciu a dekor\u00e1ciu dreva a dobre funguje aj na sten\u00e1ch. T\u00fdmto sp\u00f4sobom s\u00fa chr\u00e1nen\u00e9 pred vlhkos\u0165ou. Dobre sa hod\u00ed ako stavebn\u00e9 lepidlo na kov na ochranu povrchov vystaven\u00fdch silnej kor\u00f3zii a na tesnenie.<\/span><\/p>\n

Epoxidov\u00e1 \u017eivica na drevo<\/span><\/h2>\n

Epoxid sa m\u00f4\u017ee pou\u017ei\u0165 na vytvorenie \u010d\u00edrych odliatkov, ktor\u00e9 chr\u00e1nia a dod\u00e1vaj\u00fa jemn\u00fd lesk r\u00f4znym povrchom. Naj\u010dastej\u0161ie sa pou\u017e\u00edva v stylingu na ochranu dreven\u00fdch komponentov a v klenotn\u00edctve na uchytenie mal\u00fdch \u0161perkov. Na\u0161a spolo\u010dnos\u0165 pon\u00faka epoxidov\u00e9 \u017eivice na drevo, ktor\u00e9 okrem in\u00e9ho vyp\u013a\u0148aj\u00fa prirodzen\u00e9 \u0161trbiny dreva a v kombin\u00e1cii s vhodn\u00fdmi farbami a farbivami s\u00fa takmer nepostrehnute\u013en\u00e9.<\/span><\/p>\n

Podlahy z epoxidovej \u017eivice<\/span><\/h2>\n

Epoxidov\u00e9 podlahy sa pou\u017e\u00edvaj\u00fa predov\u0161etk\u00fdm v gar\u00e1\u017each, skladoch alebo priemyseln\u00fdch hal\u00e1ch, ale u\u017e nejak\u00fd \u010das sa \u010doraz \u010dastej\u0161ie pou\u017e\u00edvaj\u00fa ako origin\u00e1lny dekorat\u00edvny prvok v obytn\u00fdch interi\u00e9roch. Zauj\u00edmav\u00e9 podlahy zo syntetickej \u017eivice n\u00e1jdete v ob\u00fdvac\u00edch izb\u00e1ch, kuchyniach, k\u00fape\u013eniach, na teras\u00e1ch a balk\u00f3noch. M\u00f4\u017eu by\u0165 \u010d\u00edre alebo t\u00f3novan\u00e9, nanesen\u00e9 priamo na bet\u00f3nov\u00e9 alebo dreven\u00e9 podlahy a chr\u00e1ni\u0165 ich. Najv\u00e4\u010d\u0161ou v\u00fdhodou \u017eivicov\u00fdch podl\u00e1h je vytvorenie celistv\u00e9ho povrchu, ktor\u00fd dod\u00e1va interi\u00e9ru eleganciu a opticky ho zv\u00e4\u010d\u0161uje. S\u00fa zn\u00e1me nielen pre svoje zauj\u00edmav\u00e9 dekorat\u00edvne efekty, ale aj pre svoju vysok\u00fa trvanlivos\u0165, tvrdos\u0165 a odolnos\u0165 vo\u010di mechanick\u00e9mu po\u0161kodeniu. \u017divicov\u00e1 podlaha dobre odol\u00e1va ve\u013ek\u00e9mu za\u0165a\u017eeniu a je odoln\u00e1 vo\u010di po\u0161kriabaniu a oderu. Navy\u0161e sa \u013eahko \u010dist\u00ed a je vodotesn\u00fd, tak\u017ee ho mo\u017eno pou\u017e\u00edva\u0165 aj v miestnostiach s vysokou vlhkos\u0165ou. Na podlahy sa pou\u017e\u00edvaj\u00fa tenk\u00e9, hrub\u00e9 alebo hrub\u00e9 vrstvy kremennej epoxidovej \u017eivice.<\/span><\/p>\n

Nev\u00fdhody epoxidovej \u017eivice<\/span><\/h2>\n

Nev\u00fdhodou epoxidovej \u017eivice s\u00fa najm\u00e4 dva faktory: cena a sk\u00fasenosti.
