A je to tu znova: klasick\u00fd, ohniv\u00fd titulok zo soci\u00e1lnych m\u00e9di\u00ed! Ale na rozdiel od niektor\u00fdch in\u00fdch internetov\u00fdch trendov, \u201etajomstvo polystyr\u00e9nu\u201c skr\u00fdva mimoriadne fascinuj\u00faci DIY projekt, ktor\u00fd skuto\u010dne funguje.<\/p>\n\n\n\n
Nabud\u00face, ke\u010f rozbal\u00edte elektrick\u00fd spotrebi\u010d a uvid\u00edte obrovsk\u00e9 kopy bieleho polystyr\u00e9nu (EPS), nevyhadzujte ho do recykla\u010dn\u00e9ho ko\u0161a. M\u00f4\u017eete z neho vyrobi\u0165 super siln\u00e9, vodeodoln\u00e9 lepidlo, lak alebo tmel.<\/p>\n\n\n\n
Pravdepodobne u\u017e m\u00e1te doma \u201ez\u00e1zra\u010dn\u00fa ingredienciu\u201c, ktor\u00fa potrebujete.<\/p>\n\n\n\n
Fyzik\u00e1lny \u201ez\u00e1zrak\u201c: Polystyr\u00e9n + acet\u00f3n
Polystyr\u00e9n pozost\u00e1va z pribli\u017ene 98 % vzduchu, ktor\u00fd je zachyten\u00fd v tenkej polystyr\u00e9novej \u0161krupine. Ke\u010f pr\u00edde do kontaktu s \u010dist\u00fdm acet\u00f3nom (alebo odlakova\u010dom na nechty na b\u00e1ze acet\u00f3nu), stane sa nasledovn\u00e9: Acet\u00f3n rozpust\u00ed plast. Vzduch unikne v priebehu nieko\u013ek\u00fdch sek\u00fand a polystyr\u00e9n sa akoby m\u00e1vnut\u00edm \u010darovn\u00e9ho pr\u00fatika roztop\u00ed na visk\u00f3znu, lepkav\u00fa hmotu.<\/p>\n\n\n\n
\u010co budete potrebova\u0165:
Odrezky polystyr\u00e9nu (\u010dist\u00e9 a such\u00e9)
\u010cist\u00fd acet\u00f3n (dostupn\u00fd za p\u00e1r eur v \u017eeleziarstve)
N\u00e1doba so z\u00e1vitov\u00fdm uz\u00e1verom (vyroben\u00e1 zo skla \u2013 acet\u00f3n pre\u017eiera takmer v\u0161etky plasty!)
Star\u00e1 dreven\u00e1 ty\u010dinka na mie\u0161anie
Pokyny pre dom\u00e1cich majstrov: Ako vyrobi\u0165 univerz\u00e1lne lepidlo
Bezpe\u010dnos\u0165 predov\u0161etk\u00fdm: Robte to iba vonku alebo s dokor\u00e1n otvoren\u00fdm oknom. V\u00fdpary acet\u00f3nu s\u00fa vysoko hor\u013eav\u00e9 a dr\u00e1\u017edia d\u00fdchacie cesty. Najlep\u0161ie je nosi\u0165 rukavice.<\/p>\n\n\n\n
Nalejte acet\u00f3n: Nalejte mal\u00e9 mno\u017estvo acet\u00f3nu (asi 2 \u2013 3 centimetre vysok\u00e9) do n\u00e1doby.<\/p>\n\n\n\n
\u201eK\u0155menie\u201c polystyr\u00e9nu: Rozlomte polystyr\u00e9n na k\u00fasky a vtla\u010dte ich do acet\u00f3nu. Okam\u017eite sa zmr\u0161t\u00ed so sy\u010div\u00fdm zvukom. Pokra\u010dujte v prid\u00e1van\u00ed polystyr\u00e9nu, k\u00fdm sa nevytvor\u00ed visk\u00f3zna hmota (podobn\u00e1 medu alebo tekut\u00e9mu plastu).<\/p>\n\n\n\n
\u010co m\u00f4\u017eete robi\u0165 s t\u00fdmto lepidlom na polystyr\u00e9n svojpomocne?<\/p>\n\n\n\n
Ke\u010f sa acet\u00f3n na vzduchu odpar\u00ed, hmota stvrdne sp\u00e4\u0165 na tvrd\u00fd, \u00faplne vodeodoln\u00fd polystyr\u00e9nov\u00fd plast. V\u010faka tomu je mimoriadne v\u0161estrann\u00fd:<\/p>\n\n\n\n
Super odoln\u00e9 vonkaj\u0161ie lepidlo: Ide\u00e1lne na lepenie hlinen\u00fdch kvetin\u00e1\u010dov, rozbit\u00fdch dla\u017ed\u00edc alebo bet\u00f3nov\u00fdch fig\u00farok v z\u00e1hrade. Lepidlo je \u00faplne odoln\u00e9 vo\u010di poveternostn\u00fdm vplyvom a mrazu.<\/p>\n\n\n\n
Vodotesn\u00fd tmel: Tekut\u00fa hmotu m\u00f4\u017eete nanies\u0165 \u0161tetcom na drevo alebo hlinu ako lak, aby ste materi\u00e1l ochr\u00e1nili pred vlhkos\u0165ou.<\/p>\n\n\n\n
Tmel na trhliny: Ak hmotu zmie\u0161ate na mierne hustej\u0161iu konzistenciu (ako modelovaciu hlinu), m\u00f4\u017eete ju pou\u017ei\u0165 na vyplnenie dier alebo trhl\u00edn vonku. Po vytvrdnut\u00ed sa d\u00e1 prebr\u00fasi\u0165 a prema\u013eova\u0165.<\/p>\n\n\n\n
Mierny tlmi\u010d environment\u00e1lnej euf\u00f3rie<\/p>\n\n\n\n
Aj ke\u010f je n\u00e1pad d\u00f4myseln\u00fd, mus\u00edme by\u0165 \u00faprimn\u00ed: Pr\u00edsne vzat\u00e9, nejde o prav\u00fd ekologick\u00fd \u201eupcykling\u201c. Acet\u00f3n je chemick\u00e9 rozp\u00fa\u0161\u0165adlo, ktor\u00e9 sa pri odparovan\u00ed dost\u00e1va do \u017eivotn\u00e9ho prostredia. T\u00e1to met\u00f3da teda nie je vhodn\u00e1 na pou\u017eitie vo ve\u013ekom meradle \u2013 je to v\u0161ak skvel\u00fd trik na dobr\u00e9 vyu\u017eitie mal\u00e9ho mno\u017estva obalov\u00e9ho odpadu a \u00fasporu n\u00e1kladov na n\u00e1kup \u0161peci\u00e1lneho lepidla v \u017eeleziarstve.<\/p>\n\n\n\n
