Namuhla, ngokukhetha isembozo esingaphansi , asigxila ekuklanyeni nasekubukeni kwayo kuphela, kodwa futhi nangendlela efana nokuhlala nokuthembeka. Thatha isibonelo isibonelo se- laminate . Lokhu kuyinto engabizi futhi ngesikhathi esifanayo uhlobo olubonakalayo lokubheka. Ngaphandle, i-laminate ingalingisa izinto ezihlukahlukene, njengezinkuni, itshe noma tile, kanye nephalethi yombala yayo inobanzi obubanzi kakhulu. Kodwa, ngokukhetha i-laminate, abantu abambalwa bacabanga ngemininingwane ebalulekile njenge-substrate ngaphansi kwayo. Kodwa nguye oqinisekisa ukuthi izitezi ezinamathelethi zizokusiza kahle ngesikhathi sewaranti. Ngakho, yiluhlobo luni lwesigcawu sokukhethwa kwamatshe?
Kungani ngidinga i-substrate laminate?
I-substrate elungile ngaphansi kwe-laminate yenza imisebenzi eminingana:
- I-soundproof : amaminithi amancane amakhemikhali abhekene namabhodlela avame ukubekwa "indlela ehambayo", futhi ayifuni ngaso sonke isikhathi. Ngemuva kokufakwa, ukugqoka kungaveza umphumela womsindo obonakalayo uma uhamba, ikakhulukazi uma phansi ekamelweni kungakhanjiswa. I-substrate izosiza ukuyivimbela, ngoba inendawo yokufaka umsindo;
- umswakama-absorbing : i-laminate kuphela ngaphandle inomzimba onzima ogcwele ifilimu yokuvikela i-laminating. Ngakolunye uhlangothi, libukeka njengendawo evulekile eyenziwe ngothuli olunyanyisiwe futhi, eqinisweni, liyilo. Lokhu kusho ukuthi phansi kwe-laminate akuqinisekisiwe neze kumswakama. Ngalesi sizathu, kune-substrate efaka ngempumelelo i-laminate evela emswakeni ophezulu;
- Ukumangalisa : kunoma yiliphi igumbi, phansi ngisho nangemva kokuba isibani sokukhanya singase sibe nezinsalela ezincane. Ekuboneni kokuqala, azibonakali kakhulu, kepha, ngokubeka i-laminate ngaphandle kwe-substrate, uzoqiniseka ngalokhu. Ngakho-ke, ochwepheshe batusa ukusebenzisa i-substrate.
Izinhlobo zamagagasi
I-substrate ingaba nobukhulu obuhlukile futhi, ngaphezu kwalokho, ingenziwa ngezinto ezihlukahlukene.
- Faka phansi ngaphansi kwezingodo zomuthi wokhuni - indaba engokwenyama enobungozi. Lesi sigqoko sizokuhlala isikhathi eside kakhulu, ngoba ngokuhamba kwesikhathi isikhala singasebenzi futhi asilahlekelwa impahla yaso. Into ebaluleke kunazo zonke ukukhetha umkhiqizo wekhwalithi, ngoba ngaphandle kwalokho ingwebe ingase iqale ukuqubuka, bese kuthi amafomu amancane abe ngaphansi kwezibhamu ezizoholela ekuqhumeni. I-substrate yokhuni yokhuni ngaphansi kwe-laminate ibuye ihluke: isikhwama senjoloba, i-bitumen-cork, ingulube ne-cork substrate.
- I-Coniferous substrate ngaphansi kwe-laminate ayinakho ukuguquguquka, kepha "iphefumula" ngokuphelele, ngamanye amazwi - idlula umoya kahle. Ithengiswa ngamatayela, okudingeka adakwe eduze, uma kunesidingo, ukusika izimpande ngommese obukhali.
- I-polystyrene ene-foam eyandisiwe yilezi zinto ezibonakalayo ezingezansi ezigumbini lapho kulungiswa khona imithwalo emikhulu. Ibuye ibe nezakhiwo zokushisa, okuyisici esibaluleke kakhulu kuso. Phakathi kokushiyeka kwe-polystyrene enwetshiwe ayikwazi ngokwanele ikhono lokulinganisela, ubuthi obuyingozi futhi ukuthi leyo substrate, emva kweminyaka engu-7-8, ilahlekelwa yizinto zayo eziyigugu.
- I-substrate ye-foil izobe ihamba kahle emakamelweni ngesitezi esibandayo: yenza ukunciphisa ukushisa ngo-30%, inomphumela wokushisa ukushisa. Umcabango wobuciko ungaba ohlangothini bobabili be-substrate enjalo noma eyodwa kuphela (ekugcineni, isisekelo kufanele sibekwe nge-foil phezulu).
- I-substrates ehlanganisiwe , ehlanganisa i-polystyrene enwetshiwe, i-polyethylene kanye ne-rabri.
Ngokuqondene nobukhulu be-substrate, lihluka kusuka ku-0.8 kuya ku-10 mm. Khetha kufanele kube njalo: ukulingana okungaphezulu kakhulu, okuncane kakhulu okumele kube yi-substrate. Izakhiwo zokuhlala ubukhulu obuyi-2 kuya ku-4 mm zisetshenziswa.
