stdClass Object ( [id] => 1209136 [title] => Fluorougljična struna najbolje je rješenje za lov opreznih riba jer je praktički nevidljiva. No, kako se snaći u bogatoj ponudi i prepoznati pravu? [alias] => kako-prepoznati-pravu-fluorougljicnu-strunu [catid] => 419 [published] => 1 [introtext] => [fulltext] =>

Odabir vrste strune može biti presudan za kvalitetu udičarske opreme, njezinu pouzdanost te količinu, kvalitetu i veličinu budućeg ulova.

Tako je fluorougljična struna najbolje rješenje za lov plašljivih i opreznih riba jer je u moru praktički nevidljiva. No ta se struna izrađuje od poliviniliden fluorida (PVDF), spoja fluora i ugljika, koji je znatno skuplji od poliamida (PA), odnosno najlona od kojeg se izrađuje klasična udičarska struna.

Zbog toga je fluorougljična struna barem dva puta skuplja od najlonske iste debljine. To je razlog zašto se radi uštede fluorougljična struna koristi samo za izradu završnjaka (sistema) ili priveza (pjoka, prame...), ali i što se proizvode strune od kombinacije skupog fluorougljika i jeftinijeg najlona.

Prikriveni mješanci

U početku su ih pravili od mješavine tih plastičnih masa i posve ih prikladno, i prema kupcima pošteno, nazivali mješancima. Međutim, danas je malo struna koje nose oznaku hybrid, ali je puno oznaka Flurina, Fluorina, Fluoro, Fluoro-X, Fluron, Fluorocor…

Puno je i struna s fluorocoated, fluoro coated, fluoro coating i sličnim oznakama, koje su zapravo najlonske strune obučene u plašt od fluorougljika, što ih, kao ni mješance, ne čini nevidljivima.

Nažalost, na osnovi takvih imena i oznaka mnogi nedovoljno informirani udičari smatraju da se radi o gotovo nevidljivim fluorougljičnim strunama, pa umjesto takvih kupuju manje ili dobro vidljive mješance, tek nešto jeftinije.

No dobro je znati da iako nisu nevidljive, obučene i osobito strune od mješavine fluorougljika i najlona nisu loše. Dapače, različitim omjerima tih dviju plastika dobivaju se strune različitih svojstava, kakve često nemaju one od samo jedne vrste materijala.

Da bi se izbjeglo kupovanje mačka u vreći, potrebno je znati kako prepoznati fluorougljičnu strunu, odnosno razlikovati je od najlonske i hibridne strune, što je najteže.

Najlakše je i najbolje kupovati samo strunu na čijem pakiranju piše da je 100 posto fluorougljična, jer niti jedan distributer i proizvođač zbog visokih kazni nije spreman riskirati i tako označiti strunu koja to nije.

No upravo omjeri materijala uzrokuju najveće probleme u razlikovanju hibridne strune od fluorougljične i najlonske. Tako hibridna struna, čak i s malo više od 50 posto udjela fluorougljika, nakon istezanja puca kao čista najlonska – nakon što se maksimalno stanji, puca, a puknuti joj krajevi izgledaju kao vrh igle.

Fluorougljične i hibridne strune s vrlo velikim postotkom fluorougljika pucaju drukčije. One se znatno manje istežu i jedva primjetno stanjuju. Zatim se na mjestu budućeg mjesta pucanja pojavljuju uzdužne pukotine, a puknuti krajevi izgledaju kao razgranati, što se vidi na slici br. 1.

Znakovita sitna čađa

Drugi način na koji udičari samostalno mogu dosta pouzdano otkriti od koje je plastike jednonitna struna jest test paljenjem. Izvodi se tako da se kraj strune barem 20-ak sekundi drži u žuto-crvenom dijelu plamena upaljača ili palidrvca.

Najlonska struna lako se zapali, lako izgara, topi se i kaplje, a nakon što se ukloni iz plamena i ohladi, na vrhu se stvori gotovo prozirna kapljica, kao što se vidi na slici br. 2.

Fluorougljična struna, pak, teško gori, i to samo onaj dio koji se nalazi unutar plamena. Kada gorenje prestane i struna se ohladi, vrh je neravan i pougljen. Kad se protrlja između prstiju, oni pocrne od sitne čađe, a na struni ostane hrapavo zadebljanje nepravilnog oblika (slika br. 3).

Hibridne strune na testu se ponašaju ovisno o tome koja plastika čini njezin veći dio. Strune s manjim udjelom fluorougljika, a takve su gotovo sve, ponašaju se gotovo kao najlonske, s tim da im je ohlađeni kraj manje ili više crn, ovisno o udjelu fluorougljika.

Odabir vrste strune može biti presudan za kvalitetu udičarske opreme, njezinu pouzdanost te količinu, kvalitetu i veličinu budućeg ulova.

Tako je fluorougljična struna najbolje rješenje za lov plašljivih i opreznih riba jer je u moru praktički nevidljiva. No ta se struna izrađuje od poliviniliden fluorida (PVDF), spoja fluora i ugljika, koji je znatno skuplji od poliamida (PA), odnosno najlona od kojeg se izrađuje klasična udičarska struna.

Zbog toga je fluorougljična struna barem dva puta skuplja od najlonske iste debljine. To je razlog zašto se radi uštede fluorougljična struna koristi samo za izradu završnjaka (sistema) ili priveza (pjoka, prame...), ali i što se proizvode strune od kombinacije skupog fluorougljika i jeftinijeg najlona.

Prikriveni mješanci

U početku su ih pravili od mješavine tih plastičnih masa i posve ih prikladno, i prema kupcima pošteno, nazivali mješancima. Međutim, danas je malo struna koje nose oznaku hybrid, ali je puno oznaka Flurina, Fluorina, Fluoro, Fluoro-X, Fluron, Fluorocor…

Puno je i struna s fluorocoated, fluoro coated, fluoro coating i sličnim oznakama, koje su zapravo najlonske strune obučene u plašt od fluorougljika, što ih, kao ni mješance, ne čini nevidljivima.

Nažalost, na osnovi takvih imena i oznaka mnogi nedovoljno informirani udičari smatraju da se radi o gotovo nevidljivim fluorougljičnim strunama, pa umjesto takvih kupuju manje ili dobro vidljive mješance, tek nešto jeftinije.

No dobro je znati da iako nisu nevidljive, obučene i osobito strune od mješavine fluorougljika i najlona nisu loše. Dapače, različitim omjerima tih dviju plastika dobivaju se strune različitih svojstava, kakve često nemaju one od samo jedne vrste materijala.

Da bi se izbjeglo kupovanje mačka u vreći, potrebno je znati kako prepoznati fluorougljičnu strunu, odnosno razlikovati je od najlonske i hibridne strune, što je najteže.

Najlakše je i najbolje kupovati samo strunu na čijem pakiranju piše da je 100 posto fluorougljična, jer niti jedan distributer i proizvođač zbog visokih kazni nije spreman riskirati i tako označiti strunu koja to nije.

No upravo omjeri materijala uzrokuju najveće probleme u razlikovanju hibridne strune od fluorougljične i najlonske. Tako hibridna struna, čak i s malo više od 50 posto udjela fluorougljika, nakon istezanja puca kao čista najlonska – nakon što se maksimalno stanji, puca, a puknuti joj krajevi izgledaju kao vrh igle.

Fluorougljične i hibridne strune s vrlo velikim postotkom fluorougljika pucaju drukčije. One se znatno manje istežu i jedva primjetno stanjuju. Zatim se na mjestu budućeg mjesta pucanja pojavljuju uzdužne pukotine, a puknuti krajevi izgledaju kao razgranati, što se vidi na slici br. 1.

Znakovita sitna čađa

Drugi način na koji udičari samostalno mogu dosta pouzdano otkriti od koje je plastike jednonitna struna jest test paljenjem. Izvodi se tako da se kraj strune barem 20-ak sekundi drži u žuto-crvenom dijelu plamena upaljača ili palidrvca.

Najlonska struna lako se zapali, lako izgara, topi se i kaplje, a nakon što se ukloni iz plamena i ohladi, na vrhu se stvori gotovo prozirna kapljica, kao što se vidi na slici br. 2.

Fluorougljična struna, pak, teško gori, i to samo onaj dio koji se nalazi unutar plamena. Kada gorenje prestane i struna se ohladi, vrh je neravan i pougljen. Kad se protrlja između prstiju, oni pocrne od sitne čađe, a na struni ostane hrapavo zadebljanje nepravilnog oblika (slika br. 3).

Slika br.3 - Izgled izgorenog kraja 100 postotne fluorougljične strune

Hibridne strune na testu se ponašaju ovisno o tome koja plastika čini njezin veći dio. Strune s manjim udjelom fluorougljika, a takve su gotovo sve, ponašaju se gotovo kao najlonske, s tim da im je ohlađeni kraj manje ili više crn, ovisno o udjelu fluorougljika.
