\n\n\n\n

O \u010do v tomto “triku” v skuto\u010dnosti ide?<\/h2>\n\n\n\n

Nejde o varenie polystyr\u00e9nu na jedlo (to by bola katastrofa!), ale o proces zmen\u0161ovania objemu a tvarovania<\/strong>.<\/p>\n\n\n\n

1. Extr\u00e9mna recykl\u00e1cia (Zmen\u0161enie objemu)<\/h3>\n\n\n\n

Ak m\u00e1te doma hromadu polystyr\u00e9nu z obalov od elektroniky, zaber\u00e1 v ko\u0161i polovicu miesta.<\/p>\n\n\n\n

    \n
  • \u010co sa stane:<\/strong> Polystyr\u00e9n je z 98 % vzduch. Vriaca voda (alebo hor\u00faci vzduch) sp\u00f4sob\u00ed, \u017ee vzduchov\u00e9 bubliny unikn\u00fa a materi\u00e1l sa \u201escvrkne\u201c.<\/li>\n\n\n\n
  • V\u00fdsledok:<\/strong> Z obrovsk\u00e9ho kusu polystyr\u00e9nu zostane mal\u00e1, tvrd\u00e1 plastov\u00e1 gu\u013e\u00f4\u010dka. Takto m\u00f4\u017eete \u201euprata\u0165\u201c pln\u00fa gar\u00e1\u017e odpadu do jedn\u00e9ho mal\u00e9ho vreca.<\/li>\n<\/ul>\n\n\n\n

    2. V\u00fdroba “dom\u00e1ceho plastu” pre opravy<\/h3>\n\n\n\n

    Ke\u010f polystyr\u00e9n zm\u00e4kne v hor\u00facom prostred\u00ed (voda mu sl\u00fa\u017ei ako bezpe\u010dn\u00fd prenos tepla bez toho, aby hne\u010f horel), stane sa z neho tvarovate\u013en\u00e1 hmota.<\/p>\n\n\n\n

      \n
    • Trik:<\/strong> Niektor\u00ed kutilovia t\u00fato zm\u00e4knut\u00fa hmotu pou\u017e\u00edvaj\u00fa na vyplnenie dier v murive alebo ako improvizovan\u00e9 tesnenie, ktor\u00e9 po vychladnut\u00ed stvrdne na kame\u0148.<\/li>\n<\/ul>\n\n\n\n

      Lep\u0161\u00ed trik: Polystyr\u00e9nov\u00e9 lepidlo (Bez vriacej vody)<\/h2>\n\n\n\n

      Ak h\u013ead\u00e1te d\u00f4vod, pre\u010do polystyr\u00e9n u\u017e nikdy nevyhodi\u0165, vriaca voda nie je t\u00e1 najlep\u0161ia cesta. Sk\u00faste rad\u0161ej acet\u00f3n<\/strong>.<\/p>\n\n\n\n

        \n
      1. Do sklenen\u00e9ho poh\u00e1ra nalejte trochu acet\u00f3nu (riedidlo).<\/li>\n\n\n\n
      2. Vhadzujte k\u00fasky polystyr\u00e9nu. Bud\u00fa mizn\u00fa\u0165 ako v magickom triku.<\/li>\n\n\n\n
      3. Vznikne hust\u00e1, lepkav\u00e1 hmota.<\/li>\n\n\n\n
      4. Vyu\u017eitie:<\/strong> Je to extr\u00e9mne siln\u00e9 vodeodoln\u00e9 lepidlo a tmel<\/strong> na drevo, kov alebo bet\u00f3n. Po odparen\u00ed acet\u00f3nu zostane len \u010dist\u00fd, tvrd\u00fd plast.<\/li>\n<\/ol>\n\n\n\n

        Ak sa rozhodnete experimentova\u0165 s hor\u00facim polystyr\u00e9nom:<\/p>\n\n\n\n

          \n
        • Nikdy<\/strong> na to nepou\u017e\u00edvajte hrniec, v ktorom var\u00edte jedlo.<\/li>\n\n\n\n
        • Vetrajte.<\/strong> V\u00fdpary zo zohriateho polystyr\u00e9nu nie s\u00fa nie\u010do, \u010do chcete d\u00fdcha\u0165.<\/li>\n\n\n\n
        • Pozor na pop\u00e1leniny.<\/strong> Zm\u00e4knut\u00fd polystyr\u00e9n sa lep\u00ed na poko\u017eku ako hor\u00faci vosk.<\/li>\n<\/ul>\n\n\n\n
          \n

          M\u00f4j postreh:<\/strong> V\u00e4\u010d\u0161ina vide\u00ed s vriacou vodou je len vizu\u00e1lne atrakt\u00edvna “v\u00e1bni\u010dka”. Ak chcete polystyr\u00e9n naozaj vyu\u017ei\u0165, vyrobte si z neho spom\u00ednan\u00e9 lepidlo pomocou acet\u00f3nu \u2013 to m\u00e1 v dom\u00e1cnosti re\u00e1lne vyu\u017eitie.<\/p>\n<\/blockquote>\n\n\n\n
