Prach v uzavret\u00fdch miestnostiach: Odkia\u013e sa berie \u0161pina, ke\u010f tam nikto nie je?<\/p>\n\n\n\n
Zamknutie miestnosti sa jav\u00ed ako perfektn\u00e9 rie\u0161enie na udr\u017eanie \u010distoty. Zatvor\u00edme okn\u00e1, zamkneme dvere a nech\u00e1me v\u0161etko v dokonalom poriadku, presved\u010den\u00ed, \u017ee miestnos\u0165 zostane bezchybn\u00e1 cel\u00e9 t\u00fd\u017edne alebo mesiace. Ale ke\u010f po dlhom \u010dase op\u00e4\u0165 otvor\u00edme dvere, stane sa nie\u010do zvl\u00e1\u0161tne: Jemn\u00e1, siv\u00e1 vrstva pokryje n\u00e1bytok, police a podlahu. Okam\u017eite vyvst\u00e1va ot\u00e1zka: Ak nikto nevst\u00fapil do miestnosti, odkia\u013e sa berie v\u0161etok ten prach? Odpove\u010f je ove\u013ea zlo\u017eitej\u0161ia, ako by sa dalo predpoklada\u0165. V skuto\u010dnosti prach takmer nikdy \u201eneprich\u00e1dza\u201c do uzavretej miestnosti zvonku \u2013 v\u00e4\u010d\u0161ina z neho tam u\u017e bola.<\/p>\n\n\n\n
\u010co je v skuto\u010dnosti dom\u00e1ci prach: Mikroskopick\u00e1 zmes<\/p>\n\n\n\n
Mnoho \u013eud\u00ed ver\u00ed, \u017ee prach je jednoducho zemina alebo \u0161pina z ulice. V skuto\u010dnosti je dom\u00e1ci prach zlo\u017eit\u00e1 zmes r\u00f4znych materi\u00e1lov, ktor\u00e9 sa v dom\u00e1cnosti neust\u00e1le vytv\u00e1raj\u00fa. Medzi hlavn\u00e9 zlo\u017eky patria odumret\u00e9 bunky \u013eudskej poko\u017eky, drobn\u00e9 \u00falomky vlasov, textiln\u00e9 vl\u00e1kna z oble\u010denia a z\u00e1clon, ako aj pe\u013e a mikro\u010dastice z farby alebo stien. \u013dudsk\u00e9 telo ka\u017ed\u00fd de\u0148 zbavuje mili\u00f3ny ko\u017en\u00fdch buniek. Mnoh\u00e9 z nich sa vzn\u00e1\u0161aj\u00fa vo vzduchu a potom sa pomaly usadia na povrchoch. Aj ke\u010f opust\u00edme miestnos\u0165, tieto \u010dastice s\u00fa u\u017e pr\u00edtomn\u00e9 v atmosf\u00e9re alebo skryt\u00e9 v text\u00edli\u00e1ch.<\/p>\n\n\n\n
Pre\u010do nie s\u00fa uzavret\u00e9 priestory hermeticky uzavret\u00e9<\/p>\n\n\n\n
\u010castou mylnou predstavou je, \u017ee uzavret\u00fd priestor je \u00faplne izolovan\u00fd od vonkaj\u0161ieho sveta. Budovy v\u0161ak nikdy nie s\u00fa \u00faplne uzavret\u00e9. Existuj\u00fa mal\u00e9 otvory, cez ktor\u00e9 m\u00f4\u017ee cirkulova\u0165 vzduch: mal\u00e9 trhliny okolo dver\u00ed, ne\u00fapln\u00e9 tesnenie okien, otvory okolo elektrick\u00fdch z\u00e1suviek alebo vetracie \u0161achty. Cez tieto nevidite\u013en\u00e9 body prebieha pomal\u00e1 v\u00fdmena vzduchu. Tento proces je zintenz\u00edv\u0148ovan\u00fd teplotn\u00fdmi rozdielmi. Ke\u010f sa vzduch zahreje, st\u00fapa; ke\u010f sa ochlad\u00ed, kles\u00e1. Tieto tepeln\u00e9 pr\u00fady neust\u00e1le rozv\u00edria u\u017e usaden\u00fd prach a rozmiestnia ho po celej miestnosti.<\/p>\n\n\n\n
Prah Zdroj P\u00f4vod Podiel v dom\u00e1com prachu<\/p>\n\n\n\n
\u013dudsk\u00e9 a zvieracie ko\u017en\u00e9 \u0161upky, vlasy cca. 20 \u2013 50 %<\/p>\n\n\n\n

Gravit\u00e1cia: Tich\u00fd spr\u00e1vca prachu<\/p>\n\n\n\n
V akt\u00edvnej miestnosti pohyb \u013eud\u00ed udr\u017eiava prachov\u00e9 \u010dastice neust\u00e1le vzn\u00e1\u0161an\u00e9. V nepou\u017e\u00edvanej miestnosti sa deje opak: ni\u010d nepreru\u0161uje proces usadzovania. Postupom \u010dasu gravit\u00e1cia \u0165ah\u00e1 aj tie najmen\u0161ie \u010dastice smerom nadol. Ke\u010f\u017ee ch\u00f4dzou ani otv\u00e1ran\u00edm dver\u00ed nevznik\u00e1 \u017eiadne pr\u00fadenie vzduchu, prach sa rovnomerne a vidite\u013ene hromad\u00ed na stoloch, policiach a podlah\u00e1ch. Preto sa vrstva prachu v nepou\u017e\u00edvan\u00fdch miestnostiach \u010dasto jav\u00ed ove\u013ea hrub\u0161ia a roz\u0161\u00edrenej\u0161ia ako v ob\u00fdvan\u00fdch priestoroch, kde sa prach \u201erozprestiera\u201c neust\u00e1lym pohybom.<\/p>\n\n\n\n
Domy \u201eprodukuj\u00fa\u201c svoj vlastn\u00fd prach<\/p>\n\n\n\n
Domy s\u00fa vyroben\u00e9 z materi\u00e1lov, ktor\u00e9 podliehaj\u00fa prirodzen\u00e9mu procesu starnutia. Farba, drevo, omietka, izol\u00e1cia a dokonca aj bet\u00f3n sa \u010dasom mikroskopicky opotreb\u00favaj\u00fa. Kol\u00edsanie teploty sp\u00f4sobuje roz\u0165ahovanie a s\u0165ahovanie materi\u00e1lov, \u010d\u00edm sa uvo\u013e\u0148uj\u00fa drobn\u00e9 \u010dastice. To znamen\u00e1, \u017ee samotn\u00e1 kon\u0161trukcia domu prispieva k tvorbe prachu. \u010eal\u0161\u00edm faktorom je vlhkos\u0165: Pri vysokej vlhkosti prachov\u00e9 \u010dastice absorbuj\u00fa vodu zo vzduchu. St\u00e1vaj\u00fa sa \u0165a\u017e\u0161\u00edmi, \u013eah\u0161ie pri\u013en\u00fa k povrchom a vytv\u00e1raj\u00fa vrstvy, ktor\u00e9 sa odstra\u0148uj\u00fa ove\u013ea \u0165a\u017e\u0161ie ako such\u00fd prach.<\/p>\n\n\n\n

Hoci je nemo\u017en\u00e9 \u00faplne odstr\u00e1ni\u0165 prach, existuj\u00fa overen\u00e9 met\u00f3dy na minimaliz\u00e1ciu jeho \u0161\u00edrenia.

Pri \u010disten\u00ed v\u017edy pou\u017e\u00edvajte vlhk\u00e9 handri\u010dky, preto\u017ee such\u00e9 handri\u010dky \u010dasto prach len rozv\u00edria, namiesto toho, aby ho zachytili. \u010cast\u00e9 vys\u00e1vanie kobercov a z\u00e1clon je nevyhnutn\u00e9, preto\u017ee tieto text\u00edlie s\u00fa skuto\u010dn\u00fdmi magnetmi na prach. \u010cisti\u010dky vzduchu s HEPA filtrami dok\u00e1\u017eu tie\u017e filtrova\u0165 ve\u013ek\u00fa \u010das\u0165 jemn\u00e9ho prachu zo vzduchu.
