Softwood plywood: tobileng, difeme le bo bitsa. plywood WBP

Plywood - Ho aha lintho tse bonahalang entsoe ka le dikarolo kokangana patsi (veneer).

tšobotsi

The thepa motheo ea plywood itshetlehile patsi ho tloha eo e ne e entsoe. From tlotla e utloisisa hore plywood softwood e etsoa ka softwood (phaene, phaene). The magato aa veneer li ratang e le hore likhoele li ne li perpendicular mong ho e mong.

Main litšobotsi tsa lintho tse bonahalang tse:

• The theko e batlang e tlaase.
• Leseli boima tse bonahalang.
• Mamella liphetoho mocheso.
• Mongobo manganga.
• Phahameng matla ka lebaka la ho ba teng ha le dikarolo.
• Ho le bonolo ho sebelisa (ka sakhoa, e ile ea fata, 'me joalo-joalo. D.).
• E monya lerata.
• E sebeletsa e le lera la kwahelang.
• patsi e tse tsetsoeng moriana le lehoakhoa tsa tlhaho, tse etsang hore lintho tse bonahalang manganga ho hlobo le fungus e.
• manganga haholo ho mecha ea litaba ba mabifi.
• Aesthetically ntle e loketseng bonahalitseng sebopeho lehong.

mekhoa plywood difeme

Ho na le litsela tse tharo:

1. Mesebetsi. Bakeng sa patsi veneer e khaola ka e hlobolisa 5 limilimithara teteaneng. Ka mokhoa ona uneconomically chesa iphepe.
2. Slicing - ho feta litšenyehelo mokhoa ho fumana 3,5 limilimithara teteaneng veneer.
3. Gommage veneer likutung - mokhoa oo lokiseditsweng veneer botenya ba limilimithara 1.2 ho 1.9 ho.

Seo molemo plywood: birch kapa softwood?

Tse fapa-fapaneng li ka sebelisoa bakeng sa ho hlahisa mefuta e sa lehong: phaene le hardwoods. The thepa ya lintho tse bonahalang tse itshetlehile, ya e le hantle, ho tloha thepa e tala. E mong le e mofuta na le melemo ea eona e le go tlhoka mesola,.

plywood Softwood e entsoe ka palo e nyenyane ea le dikarolo. Boitsebiso bo entsoe ka larch, tsoarellang ho feta, ea itoanela 'me abrasion manganga. Bakeng sa beha dintho tsoarellang ho feta molemo ho khetha birch plywood.

Veneers tsa birch e ka bobebe moriti le botenya hampe a bontša. Conifers, ka fapana le hoo, le leso kudu le na le e ntle phatlalletsoang paterone.

lehong phaene tse tsetsoeng moriana le halogenated tlhaho. Ka lebaka la sena, thepa e entsoeng ka tsona ka tlaase ho moo o ile a pepesa ho hlobo le li-fungus. Phaene plywood - ena ke e batlang e le theko e mohaho ona o bonahalang.

tšoaea

Boleng ba boitsebiso boo itšetlehile ka sekgomaretsi eo e ne e sebelisetsoa ho hokahanya le dikarolo le veneer. Ho itšetlehile ka plywood ena softwood na markings 'maloa:

• ABF - tlaase-tlaase ka boleng ba cha ho. E etsoa sebelisa albuminkazeinovogo sekgomaretsi. E etsang hore e lintho tse bonahalang le botsoalle tikoloho. Empa mongobo lintho tse joalo ke ke mamella. E e sebediswa feela moo ho se nang sireletsa metsi.

• FSF - cha ka ho fetisisa ratoa, o ile a sebelisa phenol formaldehyde sekhomaretsi. Ho tsoarellang haholo le metsi manganga.

• PSF-TV fapane le ho FSF cha retardants impregnation. Ka lebaka la sena, mofuta ona wa plywood softwood na combustibility mafutsana.

• FC entse sebelisa urea sekhomaretsi, e leng se etsang lintho tse bonahalang tse hygroscopic haholoanyane. E sebediswa ho etsa thepa ea ka tlung, ambalaji, mehaho e ka hare.

• SE Metsi manganga ha a pepesa tikolohong e mabifi. Ho ka sebelisoa esita le tlas'a metsi. Sena se finyelloa ka o tlohang magato aa sekhomaretsi 'me tse tsetsoeng moriana le bakelite varnish tšoanang.

• , Bs - lifofane plywood, e leng a lebitso la eona le ka lebaka la kopo lona ka lifofane le shipbuilding. Bakelite veneer lamellar sekhomaretsi joala-qhibilihang ka har'a. Softwood plywood tšoaea ena keneleng metsi, tsoarellang, tenyetsehang le manganga ho mecha ea litaba ba mabifi.

• BV o na le makgetha a ho tšoanang le ha re, bs ena. Phapang feela ke hore boitsebiso ba tšoaea tšaba metsi (entse sebelisa qhibilihang ka har'a metsi sekgomaretsi).

Mefuta eohle ea plywood fapaneng holim fihlela qetellong. Ho itšetlehile ka sena, ho ke ke ea mefuta e meraro: unpolished (NSH), le a le mong-ba ema ho sila (SH1) le fatše ho tloha mahlakoreng a mabeli (R2).

PSF

Softwood plywood WBP ke ka ho fetisisa ratoa ho kaho ea merero ea lehae le indasteri. hanyetsa lona ho metsi a loketseng ho impregnation dikarolo hampe qhibilihang ka har'a formaldehyde halogenated. Mora impregnation, le dikarolo le veneer li chefo tlas'a o tobetsa ya ka mocheso phahameng.

GOST e amohelehang kabo ya ba bang ba bongata ba formaldehyde le phenol metsoako. Ena di raraanyang go tshebediso ya plywood ka kotloloho ka matlung.

PSF plywood maqephe a nang le litekanyo tekanyetso :. 1,22h2,44 limithara, 1,25h2,50 limithara, 1,525h3,050 limithara, limithara 1,525h1,525 ka nako botenya fapana ka hare ho 4-30 limilimithara.

Softwood letšoao plywood WBP e se e ho pharaletseng sebelisoa. The litaelo tsa sehlooho tsa e sebelisa ke ena:

• dibopeho nakoana nakong ea kaho.
• mehaho e sheathing.
• The lepelela tlas'a marulelong.
• Nakong ea kaho ea likoloi, likoloi le lijana bakeng sa letlalo bona.
• Ho bopa le serapa le serapeng sa rona thepa ea ka tlung.
• Bakeng sa kaho ea formwork ka (le lintho tse bonahalang tse ka sebelisoa ka makhetlo-khetlo).
• E le lintho tse bonahalang e le e tala bakeng sa tlhahiso ea thepa e 'ngoe.

Plywood - theko e tlaase le ho boleng bo phahameng tse bonahalang ho haha, e leng tse ratoang 'marakeng ka nako e telele.
