V jadre maj\u00fa tieto dve zlo\u017eky reverzn\u00e9 sily:<\/p>\n\n

Polykarbon\u00e1t (PC \/ Lexan): Ide o pevn\u00fd, siln\u00fd a opticky \u010dist\u00fd termoplast. Jeho najv\u00e4\u010d\u0161\u00edmi siln\u00fdmi str\u00e1nkami s\u00fa odolnos\u0165 vo\u010di n\u00e1razu a vizu\u00e1lna \u010distota.

Polyester (PET \/ Mylar): Ide o flexibiln\u00fa, pevn\u00fa a chemicky stabiln\u00fa f\u00f3liu. Medzi jej hlavn\u00e9 prednosti patr\u00ed chemick\u00e1 odolnos\u0165 a bezkonkuren\u010dn\u00e1 odolnos\u0165 vo\u010di \u00fanave (flexibilita). <\/p>\n\n

Bod rozhodnutia 1: Chemick\u00e1 a \u010distiaca rukavica<\/h2>\n\n

Toto je najlep\u0161\u00ed v\u00fdznamn\u00fd rozli\u0161ovac\u00ed znak. Va\u0161a environment\u00e1lna \u0161t\u00fadia (z \u010dl\u00e1nku 2) mala obsahova\u0165 zoznam v\u0161etk\u00fdch potenci\u00e1lnych chemick\u00fdch expoz\u00edci\u00ed. <\/p>\n\n

Polyester (PET): Je nesporn\u00fdm v\u00ed\u0165azom v chemickej odolnosti. Je ve\u013emi odoln\u00fd vo\u010di \u0161irok\u00e9mu spektru priemyseln\u00fdch rozp\u00fa\u0161\u0165adiel, strojn\u00fdch olejov, kysel\u00edn a siln\u00fdch \u010distiacich prostriedkov nemocni\u010dnej kvality. Nerozpad\u00e1 sa, nezakaluje sa ani nedegraduje. <\/p>\n\n

Polycarbonate (PC):<\/strong> Has weak resistance to various ordinary chemicals. Solvents and cleaners (especially those with ammonia or certain alcohols) will hit the plastic, causing „chemical stress cracking“. The material will become brittle, cloudy, and physically fail. <\/p>\n\n

\"Vizuálne

Rozhodnutie: Ak bude va\u0161a grafick\u00e1 vrstva vystaven\u00e1 nie\u010domu silnej\u0161iemu ako jemn\u00e9 mydlo a voda \u2013 najm\u00e4 v zdravotn\u00edctve, priemysle alebo stravovac\u00edch zariadeniach \u2013 polyester je jedinou bezpe\u010dnou a d\u00f4veryhodnou mo\u017enos\u0165ou.<\/p>\n\n

Bod rozhodnutia 2: Sk\u00fa\u0161ka \u00fanavovej \u017eivotnosti (stla\u010denie tla\u010didla)<\/h2>\n\n

Ak m\u00e1 v\u00e1\u0161 f\u00f3liov\u00fd predn\u00fd panel<\/a> embosovan\u00e9 tla\u010didl\u00e1 alebo je s\u00fa\u010das\u0165ou hmatov\u00e9ho membr\u00e1nov\u00e9ho sp\u00edna\u010da, toto je rozhoduj\u00faca \u010das\u0165.<\/p>\n\n

\u00danavov\u00e1 \u017eivotnos\u0165 (alebo \u201e\u017eivotnos\u0165 v ohybe\u201c) je po\u010det, ko\u013ekokr\u00e1t m\u00f4\u017ee by\u0165 materi\u00e1l skr\u00faten\u00fd alebo stla\u010den\u00fd predt\u00fdm, ako sa rozdrv\u00ed.<\/p>\n\n

Polyester (PET): Je navrhnut\u00fd presne pre toto nam\u00e1hanie. M\u00e1 nezvy\u010dajn\u00fa \u017eivotnos\u0165 v ohybe a vydr\u017e\u00ed viac ako mili\u00f3n stla\u010den\u00ed bez ak\u00fdchko\u013evek zn\u00e1mok opotrebenia alebo praskania. <\/p>\n\n

Polykarbon\u00e1t (PC): Je to pevn\u00fd komponent a nebol navrhnut\u00fd tak, aby sa oh\u00fdbal. Po embosovan\u00ed sa jeho vn\u00fatorn\u00e1 \u0161trukt\u00fara nam\u00e1ha. Po nieko\u013ek\u00fdch tis\u00edcoch stla\u010deniach sa fyzicky rozlom\u00ed a zlyh\u00e1. <\/p>\n\n

Verdikt: Toto je neod\u0148ate\u013en\u00e9 technick\u00e9 pravidlo: Ak m\u00e1 va\u0161a grafick\u00e1 krycia vrstva reli\u00e9fne gomb\u00edky, mus\u00edte pou\u017ei\u0165 polyester.<\/p>\n\n

\"Schéma
Polyester je navrhnut\u00fd tak, aby vydr\u017eal viac ako 1 mili\u00f3n stla\u010den\u00ed gomb\u00edkov bez praskania.<\/figcaption><\/figure>\n\n

Bod rozhodnutia 3: Sk\u00fa\u0161ka odolnosti vo\u010di vonkaj\u0161iemu \u017eiareniu (UV)<\/h2>\n\n

Ak bude v\u00e1\u0161 produkt b\u00fdva\u0165 vonku, bude \u010deli\u0165 neust\u00e1lemu boju so slnkom.<\/p>\n\n

Polyester (PET): Je prirodzene odoln\u00fd vo\u010di UV \u017eiareniu. Ne\u017eltne, nevybledne ani netvrdne, a to ani po mnoh\u00fdch rokoch nepretr\u017eit\u00e9ho vystavenia slne\u010dn\u00e9mu \u017eiareniu. <\/p>\n\n

Polykarbon\u00e1t (PC): \u0160tandardn\u00fd PC \u017eltne a v\u00fdrazne degraduje vplyvom UV \u017eiarenia. Hoci s\u00fa k dispoz\u00edcii aj in\u00e9, drah\u0161ie typy stabilizovan\u00e9 vo\u010di UV \u017eiareniu, polyester je spo\u013eahlivej\u0161ou a lacnej\u0161ou vo\u013ebou pre dlhotrvaj\u00face vonkaj\u0161ie pou\u017eitie. <\/p>\n\n

Verdikt: Pre vonkaj\u0161ie veci, ako s\u00fa benz\u00ednov\u00e9 pumpy, nab\u00edja\u010dky elektromobilov alebo po\u013enohospod\u00e1rske ovl\u00e1dacie prvky, je polyester najlep\u0161ou vo\u013ebou.<\/p>\n\n

Bod rozhodnutia 4: Test dopadu a jasnosti (ke\u010f vyhr\u00e1 PC)<\/h2>\n\n

Kedy je teda polykarbon\u00e1t najlep\u0161ou vo\u013ebou? Vyhr\u00e1va v aplik\u00e1ci\u00e1ch, kde s\u00fa jeho \u0161pecifick\u00e9 siln\u00e9 str\u00e1nky najvy\u0161\u0161ou prioritou. <\/p>\n\n

Vysok\u00fd n\u00e1raz: Pre ru\u010dn\u00fd skener alebo prenosn\u00fd diagnostick\u00fd n\u00e1stroj, ktor\u00fd by mohol spadn\u00fa\u0165, je pokro\u010dil\u00e1 odolnos\u0165 po\u010d\u00edta\u010da vo\u010di n\u00e1razom hlavnou v\u00fdhodou.<\/p>\n\n

Optick\u00e1 \u010distota: PC poskytuje optick\u00fa \u010distotu podobn\u00fa sklu a miernu priepustnos\u0165 svetla. V\u010faka tomu je mimoriadne \u017eiadan\u00fd pre prekryvn\u00e9 vrstvy s ve\u013emi ve\u013ek\u00fdmi, \u010dist\u00fdmi okienkami pre LCD obrazovky, za predpokladu, \u017ee sa aplikuje v interi\u00e9ri a nie s\u00fa tam reli\u00e9fne tla\u010didl\u00e1 ani nie s\u00fa vystaven\u00e9 chemik\u00e1li\u00e1m. <\/p>\n\n

\"Vysoko
Polykarbon\u00e1t poskytuje vynikaj\u00facu prieh\u013eadnos\u0165 podobn\u00fa sklu pre ve\u013ek\u00e9 LCD displeje.<\/figcaption><\/figure>\n\n

Verdikt: Polykarbon\u00e1t je skvelou a cenovo dostupnou vo\u013ebou pre vn\u00fatorn\u00fa spotrebn\u00fa elektroniku alebo mierne pou\u017e\u00edvan\u00e9 zdravotn\u00edcke pom\u00f4cky, kde je najd\u00f4le\u017eitej\u0161ou vlastnos\u0165ou jasnos\u0165 obrazovky.<\/p>\n\n
