HOM PLYWOOD BOARDS
Parameters txawv ntawm ib hom mus rau lwm tus:
● Hom ntoo siv.
● Veneer zoo.Qhov zoo ntawm cov veneers sab hauv tsis yog ib txwm teev.Txawm li cas los xij, kev hais tawm yog ua los ntawm qhov zoo ntawm cov nplooj sab nrauv lossis kim nplooj.
● Thickness ntawm nplooj thiab tag nrho.
● Bonding hom.
Raws li lawv siv los yog siv ib puag ncig.Qhov kev faib tawm no tau tsim nyob rau hauv UNE-EN 335-1 thiab UNE-EN 314-2 rau kev sib txuas zoo.
● Sab hauv (collage 1).Ua nrog urea-formaldehyde kua nplaum thiab resins.
● Sab nrauv npog lossis ib nrab sab nrauv (Glued 2).Melamine urea formaldehyde resins yog siv.
● Sab nrauv (collage 3).Nyob rau hauv hom no nws yog ib qho tsim nyog los ua ke cov ntoo nrog zoo ntuj tsis kam mus ya raws thiab rot, ua ke nrog phenolic kua nplaum.
Raws li cov ntoo siv.Ntau cov ntoo tuaj yeem siv rau kev tsim cov plywood, muab lawv cov khoom siv rau qhov tshwm sim.Yog li ntawd, birch plywood tsis zoo ib yam li okume plywood.
Tab sis nws tsis yog tsuas yog ntoo hauv nqe lus nug, tab sis kuj yog qhov zoo uas nws tau xaiv.Nws yog kev cai, nyob rau hauv cov ntaub ntawv kev sib raug zoo, hais txog qhov zoo ntawm lub ntsej muag, nraub qaum thiab sab hauv daim hlau.Nws yog qhov uas tib yam tsis yog nrhiav thaum siv lub rooj tsavxwm tsim, zoo li thaum nws siv los ua rooj tog.
Cov ntoo tseem ceeb siv hauv plywood boards: Birch, okume, sapelly, poplar, calabó, walnut, cherry, ntoo thuv lossis eucalyptus.Ib tug yam ntxwv ntawm cov ntoo yog hais tias lawv ua tau zoo tiv thaiv unwinding, lub ntsiab txheej txheem rau tau txais veneers nyob rau hauv cav.
Qee lub sij hawm, ntoo yog siv uas ib tug priori tsis yog qhov zoo tshaj plaws rau ntau yam.Piv txwv li, ntoo thuv lossis spruce tuaj yeem siv los ua lub rooj tsavxwm rau kev lag luam lossis cov qauv siv vim nws tus nqi qis, lossis ntau cov ntoo zoo nkauj zoo li ntoo qhib tab tom nrhiav rau qhov ntawd.
Kev sib xyaw ntawm cov ntoo lossis cov plywood sib xyaw kuj muaj ntau.Hom tsiaj uas zoo dua qub lossis zoo nkauj rau lub ntsej muag yog siv feem ntau, thiab cov tsiaj pheej yig dua rau cov veneers sab hauv.
Triplay.Lub tswv yim no tau pib siv los tham txog plywood ua los ntawm peb nplooj ntawv.Txawm li cas los xij, niaj hnub no lub tswv yim tau nthuav dav thiab siv los tham txog plywood feem ntau.
Phenolic plywood.Adhesives raws li phenolic resins yog siv los tsim hom duab los qhia.Hom nplaum no tso cai rau lub phaj siv rau hauv qhov chaw ntub dej thiab sab nraum zoov.
Yog tias peb tseem siv ntoo nrog cov khoom zoo rau kev siv sab nraud (lossis kho), peb tau txais qhov hu ua marine plywood.Yav dhau los lawv tau hu ua WBP (Dej boiled pov thawj), tab sis cov kev cai tshiab nyob sab Europe catalog lawv nyob rau hauv no txoj kev.
Bodyboard los yog Finnish plywood.Nws yog chav kawm ntawm plywood nrog lub npe zoo vim nws txoj kev vam meej lossis kev thov.Birch ntoo yog siv thiab tom qab ntawd lub vaj huam sib luag yog them nrog phenolic zaj duab xis uas txhim kho nws cov kev tiv thaiv kom puas, poob siab thiab ya raws.Cov txheej txheej sab nrauv no kuj ntxiv cov khoom tsis zoo, yog li nws yog siv los ua hauv pem teb, lawj rau cov nkoj thiab ua cov khoom thauj khoom hauv cov tsheb thauj khoom lossis cov tsheb thauj khoom.
Melamine plywood.Lawv yog melamine-coated plywood nrog lub hom phiaj kom zoo nkauj.Txawm hais tias nws yog ib qho uas pom lawv feem ntau hauv cov xim dawb, xws li dawb lossis grey, lawv tuaj yeem pom ua raws li lwm cov ntoo.
Lub tswv yim yog los txo cov nqi cuam tshuam nrog kev ua tiav thiab ua kom lawv tsis kam ua kom puas los yog kev sib txhuam.
SIV PLYWOOD boards
● Kev siv tus qauv.Nws nthuav tawm qhov zoo tshaj plaws binomial nyob rau hauv ib lub tsev: lightness thiab kuj.ru tsev, pem teb, formwork, laj kab, sib xyaw beams ... Hauv kev siv no, OSB boards tau dhau los ua ib qho kev hloov pauv, feem ntau vim lawv cov nqi qis dua.
