Nikel je kov, ktor\u00fd dnes sp\u00f4sobuje jednu z\u00a0najtypickej\u0161\u00edch ko\u017en\u00fdch alergii. Je na\u0148 alergick\u00e1 desatina popul\u00e1cie, hlavne v\u010faka opakovan\u00e9mu vystavovaniu sa vysok\u00fdm d\u00e1vkam. Nikel m\u00f4\u017eeme n\u00e1js\u0165 vo v\u00e4\u010d\u0161\u00edch mno\u017estv\u00e1ch napr\u00edklad v telef\u00f3noch, minciach, zipsoch, r\u00e1moch okuliarov, prack\u00e1ch, gomb\u00edkoch, no\u017eniciach \u010di k\u013e\u00fa\u010doch. Do n\u00e1\u0161ho tela sa ale naj\u010dastej\u0161ie dost\u00e1va cez \u0161perky. Alergick\u00e1 reakcia sa prejavuje za\u010dervenan\u00edm, opuchom, vyr\u00e1\u017ekou \u010di pupen\u010dekmi, ktor\u00e9 sa dostavia v\u00e4\u010d\u0161inou do dvoch dn\u00ed od nosenia \u0161perku s\u00a0obsahom niklu. D\u00f4vodom pre\u010do sa do \u0161perkov prid\u00e1va je jeho n\u00edzka cena a\u00a0vlastnosti, ktor\u00e9 \u0161perkom d\u00e1va.<\/p>\n
Nikel nie je probl\u00e9m len lacn\u00fdch \u0161perkov z\u00a0\u010c\u00edny a\u00a0m\u00f4\u017ee sa nach\u00e1dza\u0165 aj v\u00a0\u0161perkoch z drah\u00fdch kovov.<\/p>\n
Pri pozl\u00e1ten\u00fdch \u010di postriebren\u00fdch \u0161perkoch sa nikel pou\u017e\u00edva ako bari\u00e9ra medzi farebn\u00fdm kovom obsahuj\u00facim me\u010f a\u00a0t\u00fdmi drah\u00fdm. D\u00f4vodom je zabr\u00e1nenie dif\u00fazie at\u00f3mov medi do pozl\u00e1tenia\/postriebrenia, \u010do by sp\u00f4sobilo s\u010dernenie a\u00a0kazy na \u0161perku. Nikel sa d\u00e1 v\u00a0tomto pr\u00edpade nahradi\u0165 napr\u00edklad pal\u00e1diom, ktor\u00e9 je ale nieko\u013eko kr\u00e1t drah\u0161ie. Aj \u00a0ke\u010f je \u0161perk obalen\u00fd vo vrstve zlata, to sa m\u00f4\u017ee po ur\u010ditom \u010dase nosenia o\u0161\u00facha\u0165 a\u00a0ko\u017ea sa dost\u00e1va do styku s\u00a0niklovou vrstvou.<\/p>\n
Nikel v\u0161ak m\u00f4\u017eeme n\u00e1js\u0165 aj v\u00a0zlat\u00fdch \u010di strieborn\u00fdch \u0161perkoch. Ke\u010f\u017ee striebro ani zlato sa na \u0161perky nepou\u017e\u00edva vo svojej \u010distej forme, m\u00f4\u017ee sa sta\u0165 \u017ee \u010das\u0165 zliatinov\u00e9ho kovu je nikel. U\u00a0strieborn\u00fdch \u0161perkov 925 by mal by\u0165 zvy\u0161n\u00fd kov o\u00a0mno\u017estve 7.5% pr\u00e1ve me\u010f ale ani na to sa \u00faplne ned\u00e1 spo\u013eahn\u00fa\u0165. Pr\u00e1ve alergia na striebro je najpravdepodobnej\u0161ie alergia na nikel obsiahnut\u00fd v\u00a0striebre.<\/p>\n
Napr\u00edklad u\u00a0zlata sa nikel \u010dasto dal n\u00e1js\u0165 pri bielom 18k zlate na dodanie bielej farby v\u00a0kombin\u00e1cii zo zinkom a striebrom. Dnes sa \u010dastej\u0161ie do bieleho zlata prid\u00e1va pal\u00e1dium ale nie je to pravidlo, ke\u010f\u017ee farba tohto zlata je \u0161ed\u0161ia a\u00a0aj \u0161perk je v\u00fdrazne drah\u0161\u00ed. Dr\u017ete sa ale pravidla, \u017ee ak nie je uvedene \u017ee biele zlato neobsahuje nikel je pravdepodobn\u00e9, \u017ee ho tam n\u00e1jdete. Tie\u017e nie a\u017e tak podstatn\u00e9 ko\u013eko niklu \u0161perk obsahuje ale ko\u013eko sa zo \u0161perku uvo\u013e\u0148uje do poko\u017eky.<\/p>\n
Ak som sa rozhodol pre k\u00fapu \u0161perku, v\u00fdrobca aj predajca by mi mal vedie\u0165 poveda\u0165 ak\u00e9 kovy \u0161perk obsahuje. Ak nakupujeme napr\u00edklad pozl\u00e1ten\u00e9 k\u00fasky v\u00a0Eur\u00f3pe tie, by mali sp\u013a\u0148a\u0165 normy EU, ktor\u00e9 reguluj\u00fa ko\u013eko niklu sa uvo\u013e\u0148uje do tela, a\u00a0t\u00fdm predch\u00e1dza\u0165 vzniku \u010fal\u0161\u00edch alergii, ale to n\u00e1m ve\u013emi nepom\u00f4\u017ee ak u\u017e alergiu m\u00e1me. V\u00fdrobcovia nie s\u00fa povinn\u00fd uv\u00e1dza\u0165 \u010di \u0161perk nikel obsahuje. Ak ale \u0161perk nikel neobsahuje, predajca si to m\u00f4\u017ee pri svojich \u0161perkoch uvies\u0165 a\u00a0tak z\u00edska\u0165 trhov\u00fa v\u00fdhodu.<\/p>\n
Ak som si u\u017e \u0161perk k\u00fapil a\u00a0chcem zisti\u0165 \u010di nikel obsahuje, existuje nede\u0161trukt\u00edvna met\u00f3da, ktorou k\u00fasok otestujeme. Pou\u017e\u00edva sa l\u00e1tka Dimethylglyoxime, ktora ale reaguje aj na pritomnost paladia. Touto met\u00f3dou si m\u00f4\u017eete \u0161perk otestova\u0165 aj pred k\u00fapou ak v\u00e1m to predajca dovol\u00ed. Nesmieme ale zab\u00fada\u0165 \u017ee pri pozl\u00e1ten\u00fdch, postriebren\u00fdch \u010di porhodiovan\u00fdch \u0161perkoch sa nikel m\u00f4\u017ee schov\u00e1va\u0165 a\u017e pod touto vrstvou . Dokonca aj strieborne \u0161perky sa e\u0161te dodato\u010dne striebra pre vytvorenie bezchybn\u00e9ho vzh\u013eadu.<\/p>\n
M\u00f4\u017ee \u00eds\u0165 o\u00a0 k\u00fasok z\u00a0u\u0161\u013eachtil\u00e9ho aj neu\u0161\u013eachtil\u00e9ho kovu, ktor\u00fd je pr\u00edli\u0161 ob\u013e\u00faben\u00fd aby sme sa ho zbavili. V\u00a0tomto pr\u00edpade je viac mo\u017enost\u00ed:<\/p>\n
Zlat\u00fd strieborn\u00fd \u010di mosadzn\u00fd \u0161perk si m\u00f4\u017ee\u0161 da\u0165 pozl\u00e1ti\u0165, postriebri\u0165 \u010di porhodhiova\u0165. V\u00a0pr\u00edpade \u0161perku z\u00a0farebn\u00fdch kovov treba komunikova\u0165, \u017ee ako podkladov\u00fa vrstvu nemaj\u00fa pou\u017ei\u0165 nikel ale pal\u00e1dium. Z\u00e1rove\u0148 by sa pri procese pozlacovania mala odstr\u00e1ni\u0165 predo\u0161l\u00e9 pozl\u00e1tenie \u010diasto\u010dne aj s\u00a0niklom, tak\u017ee by sme sa nemuseli ob\u00e1va\u0165, \u017ee budeme znovu niklu vystaven\u00fd aj po opotrebovan\u00ed vrchnej vrstvy. Ak chceme aby \u0161perk vydr\u017eal pozl\u00e1ten\u00fd naozaj dlho m\u00f4\u017eeme sa v\u00a0zlatn\u00edctve dohodn\u00fa\u0165 na hrub\u0161ej vrstve pozl\u00e1tenia.<\/p>\n
Dom\u00e1ci sp\u00f4sob ako zabr\u00e1ni\u0165 styku niklu s poko\u017ekou je natretie \u010dasti \u0161perku, ktor\u00e1 prich\u00e1dza do kontaktu s\u00a0poko\u017ekou, lakom, napr\u00edklad t\u00fdm na nechty. Lak sa tie\u017e po ur\u010ditej dobe o\u0161\u00facha preto je ho potrebn\u00e9 aplikova\u0165 pravidelne.<\/p>\n
Nikel by nemal by\u0165 \u017eiaden stra\u0161iak ktor\u00fd n\u00e1s bude po nociach m\u00e1ta\u0165. Nach\u00e1dza sa vo ve\u013ea potravin\u00e1ch a\u00a0je dokonca nevyhnutn\u00fd pre n\u00e1\u0161 \u017eivot. Je ale pravda \u017ee dnes ho do tela prij\u00edmame v\u00a0nadmern\u00fdch mno\u017estv\u00e1ch, ktor\u00e9 sa m\u00f4\u017eu po \u010dase prejavi\u0165 ako ko\u017en\u00e1 dermatit\u00edda a\u00a0alergia ktor\u00e1 n\u00e1m zbyto\u010dne skomplikuje \u017eivot. Je to jeden z\u00a0d\u00f4vodnou pre\u010do je dobr\u00e9 vedie\u0165 od koho a ak\u00e9 \u0161perky nakupujem.<\/p>\n
