1\u3001 Princip \u010dinnosti membr\u00e1nov\u00e9ho lisu<\/strong><\/p>\n

Vyu\u017eit\u00edm plasticity PVC a nastaven\u00edm a \u0159\u00edzen\u00edm doby p\u0159\u00edtlaku membr\u00e1ny, teploty v komo\u0159e za\u0159\u00edzen\u00ed a tlaku vzduchu se PVC zah\u0159\u00edv\u00e1 a pod tlakem pokr\u00fdv\u00e1 povrch obrobku.<\/p>\n

2\u3001 Pracovn\u00ed proces membr\u00e1nov\u00e9ho lisu<\/strong><\/p>\n

(1) Polo\u017ete obrobek na pracovn\u00ed st\u016fl;<\/p>\n

(2) Pracovn\u00ed st\u016fl vstupuje p\u0159\u00edmo pod topnou desku;<\/p>\n

(3) Zav\u0159ete topnou desku s pracovn\u00edm stolem;<\/p>\n

(4) Vzduch mezi topnou deskou a silikonovou f\u00f3li\u00ed je ods\u00e1v\u00e1n a silikonov\u00e1 f\u00f3lie je adsorbov\u00e1na na topnou desku pro oh\u0159ev;<\/p>\n

(5) Po dosa\u017een\u00ed nastaven\u00e9ho \u010dasu se mezi topnou desku a silikonovou f\u00f3lii vst\u0159\u00edkne stla\u010den\u00fd vzduch. Silikonov\u00e1 f\u00f3lie je v t\u011bsn\u00e9m kontaktu s PVC a obrobek i PVC se zah\u0159\u00edvaj\u00ed. Sou\u010dasn\u011b doch\u00e1z\u00ed ke zm\u011bk\u010den\u00ed PVC a teplota na okraji desky dos\u00e1hne aktiva\u010dn\u00ed teploty lepidla;<\/p>\n

(6) Vzduch mezi pracovn\u00edm stolem a PVC se rychle odsaje, aby se vytvo\u0159il podtlak, a pot\u00e9 se mezi PVC a topnou desku vst\u0159\u00edkne stla\u010den\u00fd vzduch. PVC se na desku nabal\u00ed pod nastaven\u00fdm tlakem a teplotou.<\/p>\n

Membr\u00e1nov\u00fd lis, zn\u00e1m\u00fd tak\u00e9 jako vakuov\u00fd membr\u00e1nov\u00fd lis nebo membr\u00e1nov\u00fd vakuov\u00fd lis, je stroj pou\u017e\u00edvan\u00fd p\u0159i zpracov\u00e1n\u00ed d\u0159eva a v\u00fdrob\u011b vrstven\u00fdch v\u00fdrobk\u016f.

Zde je pops\u00e1no, jak funguje typick\u00fd membr\u00e1nov\u00fd lis:<\/p>\n

P\u0159\u00edprava:<\/strong><\/p>\n

Nejprve pracovn\u00edk p\u0159iprav\u00ed podklad (nap\u0159. d\u0159ev\u011bnou desku nebo d\u00edl) nanesen\u00edm lepidla. Toto lepidlo p\u0159i p\u016fsoben\u00ed tepla a tlaku spoj\u00ed dekorativn\u00ed materi\u00e1l nebo lamin\u00e1t s podkladem.<\/p>\n

Pokl\u00e1dka dekorativn\u00edho materi\u00e1lu:<\/strong><\/p>\n

Dekorativn\u00ed materi\u00e1l, kter\u00fdm je obvykle pru\u017en\u00e1 PVC nebo termoplastick\u00e1 f\u00f3lie s dekorativn\u00edm vzorem (nap\u0159. se strukturou d\u0159eva nebo jednobarevn\u00fdm vzorem), se um\u00edst\u00ed na podklad pokryt\u00fd lepidlem. Tento materi\u00e1l se stane viditeln\u00fdm povrchem hotov\u00e9ho v\u00fdrobku.<\/p>\n

Um\u00edst\u011bn\u00ed v tisku:<\/strong><\/p>\n

Podklad a dekorativn\u00ed materi\u00e1l se pot\u00e9 vlo\u017e\u00ed do membr\u00e1nov\u00e9ho lisu. Lis se skl\u00e1d\u00e1 z komory nebo r\u00e1mu, nad kter\u00fdm je zav\u011b\u0161ena pru\u017en\u00e1, \u017e\u00e1ruvzdorn\u00e1 membr\u00e1na nebo silikonov\u00fd s\u00e1\u010dek.<\/p>\n

Vytvo\u0159en\u00ed pe\u010deti:<\/strong><\/p>\n

Membr\u00e1na se spust\u00ed tak, aby se dostala do kontaktu s dekorativn\u00edm materi\u00e1lem a podkladem. Na okraj\u00edch by m\u011bla vytvo\u0159it t\u011bsn\u00e9 t\u011bsn\u011bn\u00ed, aby vznikla vzduchot\u011bsn\u00e1 komora.<\/p>\n

Vakuum a teplo:<\/strong><\/p>\n

Lis je vybaven vakuov\u00fdm syst\u00e9mem. Po aktivaci odstran\u00ed vzduch z komory mezi membr\u00e1nou a substr\u00e1tem. T\u00edm se v komo\u0159e vytvo\u0159\u00ed podtlak nebo negativn\u00ed tlak.<\/p>\n

Topn\u00e9 prvky:<\/strong><\/p>\n

Lis obsahuje tak\u00e9 topn\u00e1 t\u011blesa, jako jsou elektrick\u00e9 topn\u00e9 panely nebo infra\u010derven\u00e9 lampy. Tyto prvky vytv\u00e1\u0159ej\u00ed teplo a jsou um\u00edst\u011bny nad nebo pod membr\u00e1nou.<\/p>\n

Aktivace:<\/strong><\/p>\n

Vakuum a teplo se aktivuj\u00ed sou\u010dasn\u011b. Vakuum t\u011bsn\u011b obt\u00e1hne pru\u017enou membr\u00e1nu kolem dekora\u010dn\u00edho materi\u00e1lu a podkladu a rovnom\u011brn\u00fdm tlakem je p\u0159itla\u010d\u00ed k sob\u011b. Teplo z\u00e1rove\u0148 aktivuje lepidlo a zp\u016fsob\u00ed jeho spojen\u00ed dekora\u010dn\u00edho materi\u00e1lu s podkladem.<\/p>\n

Vytvrzov\u00e1n\u00ed a chlazen\u00ed:<\/strong><\/p>\n

Topn\u00e1 t\u011blesa udr\u017euj\u00ed po\u017eadovanou teplotu pro spr\u00e1vn\u00e9 vytvrzen\u00ed lepidla. Tento proces vytvrzov\u00e1n\u00ed m\u016f\u017ee trvat n\u011bkolik minut. Po vytvrzen\u00ed se teplota postupn\u011b sni\u017euje, aby se lepen\u00e9 materi\u00e1ly ochladily a zpevnily.<\/p>\n

Uvoln\u011bn\u00ed a odstran\u011bn\u00ed:<\/strong><\/p>\n

Po dokon\u010den\u00ed procesu vytvrzov\u00e1n\u00ed a chlazen\u00ed se uvoln\u00ed vakuum a pru\u017en\u00e1 membr\u00e1na se zvedne. Nalepen\u00fd dekorativn\u00ed materi\u00e1l je nyn\u00ed bezpe\u010dn\u011b p\u0159ipevn\u011bn k podkladu a p\u0159izp\u016fsobuje se jeho tvaru.<\/p>\n

O\u0159ez\u00e1v\u00e1n\u00ed a dokon\u010dov\u00e1n\u00ed:<\/strong><\/p>\n

Dokon\u010dovac\u00ed a dokon\u010dovac\u00ed pr\u00e1ce: V\u00fdrobek s dekorativn\u00edm materi\u00e1lem pevn\u011b p\u0159ilepen\u00fdm k podkladu m\u016f\u017ee b\u00fdt podroben dal\u0161\u00edm dokon\u010dovac\u00edm proces\u016fm, jako je o\u0159ez\u00e1v\u00e1n\u00ed hran, brou\u0161en\u00ed nebo dal\u0161\u00ed opracov\u00e1n\u00ed, aby se dos\u00e1hlo po\u017eadovan\u00fdch kone\u010dn\u00fdch rozm\u011br\u016f a vzhledu.<\/p>\n

Membr\u00e1nov\u00fd lis zaji\u0161\u0165uje konzistentn\u00ed a rovnom\u011brn\u00e9 nan\u00e1\u0161en\u00ed dekorativn\u00edch materi\u00e1l\u016f, eliminuje vr\u00e1sky, vzduchov\u00e9 bubliny a dal\u0161\u00ed vady, kter\u00e9 se mohou vyskytnout p\u0159i ru\u010dn\u00edm nebo m\u00e9n\u011b kontrolovan\u00e9m zp\u016fsobu laminov\u00e1n\u00ed.
