Description
Izum se odnosi na postupak strujno dinamičke proizvodnje vlaknastih hasura promjenjivog oblika, visoke čvrstoće trganja iz vlaknastog runa, koje se sastoji i, sa veznim sredstvom impregniranih vlakana celuloze i termoplastičnih vlakana i/ili prirodnih vlakana biljnog porijekla pri čemu se grumen od vlaknastog runa miješa u bačvastom spremniku i iz te mješavine se formira vlaknasto runo, koje se sa igličastim strojem učvršćuje u vlaknastu hasuru. Izum se odnosi dalje na primjeru ovim postupkom proizvedene hasure kao i postrojenja za provedbu ovoga postupka.
Postupak spomenute vrste poznat je iz AT-PS 387.798. Prema prednostima ovog poznatog postupka miješa se vlaknasto runo u bačvastom spremniku i iz te mješavine stvaraju se npr. sljedeća runa na jednom bubnju za polaganje runa. kod toga se pokazalo, da transport razvlaknjene vlaknaste mase proizlazi besciljno od valjka bačvastog spremnika od bubnja za polaganje runa, pri čemu dolazi do nepravilnosti vlaknastog grumena na bubnju za polaganje runa kao što su nepravilno raspoređivanje površinske težine po širini vlaknastog runa. Dalje se kod toga uočava, da kod drvenih vlakana impregniranih sa umjetnom smolama uglavnom dolazi radi njihove velike težine do nalijeganja donje strane runa koje se polaže, dok se istovremeno termoplastična i/ili neimpregnirana prirodna vlakna biljnog porijekla raspoređuju u gornjim slojevima runa koje se polaže. Ova različita slojevitost vodi s time do problema kod daljnje obrade ovih hasura, budući da je donja strana hasura radi njenog previsokog dijela veznih sredstava ljepljiva, dok gornja strana gotovo uopće nije zalijepljena.
Postavljeni zadatak u ovom izumu se sastoji međutim od toga, da jedna hasura promjenjivog oblika visoke čvrstoće trganja treba posjedovati ravnomjernu težinsku raspoređenost po njenoj širini kao i po njenim slojevima, koja se sastoji iz ravnomjerno izmiješanih vlakana impregnirane i neimpregnirane vrste.
Ovaj zadatak se rješava postupkom prema izumu na taj način, da se runski grume 2,2’ dovodi bačvastom spremniku 6,6’ u kojem se grumen od vlaknastog runa razvlakni i da se na taj način nastala vlaknasta masa 14,14’ miješa strujom zraka čiji profil nastrujavanja se uspostavlja kroz jedan zračni kanal 10,10’ i u njemu primijenjene elemente za regulaciju 25, 26 kao i preko jedne u smjeru strujanja priključene venturi poluge 7,7’, pri čemu se stvara runo 18,18’ sa jednim ravnomjernim rasporedom površinske težine, koja se nakon izvršenog igličanja dovodi tlačnoj napravi 21,21’ pri čemu se proizvode hasure promjenjivog oblika i visoke čvrstoće trganja 23,23’.
Postupa u svezi sa izumom je nadalje naznačen time, da se elementi za regulaciju sastoje iz više, preko širine zračnog kanala 10 raspoređenih klapni 25 i iz više prema zračnoj struji konveksno zakrivljenih dijelova za regulaciju 26 čija se zaobljenost može namještati.
Izum se odnosi nadalje na prednosti primjene hasure proizvedenih prema izumu, koje je naznačeno time, da se primjenjuju jedna ili više hasura 23,23’ primjenjuju za proizvodnju određenih oblika prešanjem pod povišenim tlakom i temperaturom.
Izum se odnosi također na jedno postrojenje sa prednostima za strujno dinamičku proizvodnju hasura promjenjivog oblika i visoke čvrstoće trganja iz vlaknastog runa, koje se sastoji iz, sa vezivnim sredstvom impregniranih celuloznih vlakana i termoplastičnih vlakana i/ili prirodnih vlakana biljnog porijekla, koje je naznačeno time, da se postrojenje sastoji, prema protoku materijala jedan a drugim poredanih od stroja za polaganje runa 1, para valjaka za prešanje 3, 4, para valjaka za uvlačenje 5, bačvastog spremnika 6, zračnog kanala 10, koji se napaja ventilatorima 12 i u kojemu su pridodani jedan ili više dijelova za regulaciju 25 u obliku jedne ili više klapni za regulaciju, venturi poluge 7, difuzora 13, bubnja za polaganje runa 15, valjaka za transport 16, 17, mjerne naprave za izmjeru površinske težine 19, igličastog stroja 20, preše 21, stroja za rezanje 22, i naprave za odlaganje 24.
Nadalje se izum odnosi na jedno postrojenje sa prednostima za strujno dinamičku proizvodnju hasura promjenjivog oblika, visoke čvrstoće trganja iz vlaknastog runa koje se sastoji iz, sa veznim sredstvom impregniranih vlakana celuloze i termoplastičnih vlakana i/ili prirodnih vlakana biljnog porijekla pri čemu je postrojenje naznačeno time da se ono sastoji, prema protoku materijala jedan za drugim poredanih, od stroja za polaganje runa 1’, para valjaka za prešanje 3’, 4’, para valjaka za uvlačenje 5’, bačvastog spremnika 6’, kanala za zrak 10’, koji se napaja ventilatorima 12’ u kojima su postavljeni jedan ili više elemenata za regulaciju 26, koji su prema struji zraka konveksno zakrivljeni i čija se zakrivljenost može namještati, venturi poluge 7’, difuzora 13’, bubnja za polaganje runa 15’, valjaka za transport 16’, 17’, mjerne naprave za izmjeru površinske težine 19’, igličastog stroja 20’, preše 21’, stroja za rezanje 22’ i naprave za odlaganje 24’.
Slika 1 prikazuje izvedbu postupka prema izumu s pomoću postrojenja koje sadrži dijelove za regulaciju u obliku pomičnih klapni.
Slika 2 pokazuje izvedbu postupka prema izumu s pomoću postrojenja naznačenog crtkano na odgovarajućem crtežu, koja sadrži konveksno savinute dijelove za regulaciju u zračnoj struji.
Slike 3 i 4 pokazuju u perspektivi principijelni prikaz venturi poluge sa shematskim protokom zračne struje postavljene kao dio za regulaciju u postupku.
Strojem za proizvodnju runa (1,1’) se iz jedne smjese koja se sastoji iz npr. sa veznim tkivom poput duroplasta, termoplasta ili elastomera ili mješavina iz toga impregniranih i nakon toga osušenih vlakana celuloze, i termoplastičnih vlakana npr. poliester-, poliolefin-, poliamid-, poliakril- EVA- i/ili prirodna vlakna kao lanena-, kudeljina- i celulozna vlakna, stvara runski grumen (2,2’). Ovaj se nadalje zgušnjava preko valjaka za prešanje (3,3’, 3,3’) i s pomoću jednog para valjaka za uvlačenje (5,5’), se dovodi bačvastom spremniku (6,6’), čije površina je obložena sa iglama ili reznim zupčanicima koji razvlaknjuju runasti grumen. Prema broju preko iste osovine zagonjenih ventilatora 12,12’ se u kanalu zrak 10,10’ stvara zračna struja, čija brzina strujanja se uspostavlja kroz više raspoređenih dijelova za regulaciju 25, 26 (vidi sliku 2) preko širine kanala za zrak u obliku klapni za namještanje. Dijelovi za regulaciju 25 (vidi sliku 1) su prema struji zraka konveksno zakrivljeni i njihova se zakrivljenost može namještati.
Miješanje vlakana u struji zraka je nadalje ovisno o brzini strujanja. Ovo miješanje se pojačava zakretanjem venturi poluge 7,7’ za približno + 30° oko njene osi, koja po njenoj širini ukazuje varirajuće prepreke 8,8’. U međuprostorima 9,9’ (vidi sliku 3 i 4) između prepreka 8,8’ povećava se prema veličini međuprostora brzina strujanja smjese zrak-vlakna, čime slijedi dodatno miješanje vlakana u priključenom difuzoru 13,13’. Nadalje takova brzina strujanja proizvodi jedan učinak lopatica koji omogućuje pravilno rasprostranjivanje runa vlakana 14,14’ na bubanj za proizvodnju runa 15,15’. Na takav način novostvoreno runo 18,18’ se dovodi preko valjaka za transport 16,16’ i 17,17’ napravi za mjerenje površinske težine 19,19’. Ove izmjere ukazuju na pravilnu raspodjelu površinske težine kao i rezultat mjerenja, koji se može potiči poznatim postupkom stvaranja runa. Bude li usprkos toga raspored površinske težine nedovoljno dobar, moguće ga je promjenom brzine strujanja namještanjem jednog ili više dijelova za regulaciju 25, 26 promijeniti. Nadalje je preko mogućnosti namještanja venturi poluge 7,7’ dana daljnja mogućnost optimiranja strujnih odnosa.
U igličastoj mašini 20,20’ koja slijedi u aparaturi, isprepleće se runo 18,18’ sa jednim drugim runom 27,27’, npr. koje se sastoji iz poliester-, poliamid-, staklasta vlakna ili jute, čime se stvara jedna hasura 28,28’ dovoljno dobrog promjenjivog oblika. Da bi se postigla još bolja promjenjivost oblika ove hasure kod daljnje prerade u prešama za formiranje, ona se vodi kroz napravu za prešanje 21,21’, koja može biti npr. roljača ili trakasta preša. Između valjaka roljače se predzgušnjava hasura na temperaturi od 25°C do 150°C i specifičnom tlaku od 5 do 50 kp/cm2 pri čemu se drvena vlakna impregnirana sa umjetnim smolama još jače vežu na dodatna vlakna. Na taj način može hasura kod daljnje obrade npr. kod prešanja u forme preuzeti još veće vlačne sile i stoga je manje podložna stvaranju riseva.
Dodatno se pretzgušnjena hasura 24,24’ odlaže nakon prolaza stroja za rezanje 22,22’ na napravu za odlaganje 23,23’.
