Plywood yog ib qho ntawm cov ntaub ntawv yooj yim tshaj plaws thiab pheej yig, uas tau nquag siv hauv kev tsim kho kev lag luam . Muaj ntau hom nws, hnub no peb yuav txiav txim siab ob ntawm lawv: FC thiab FSF. Txawm hais tias lawv zoo ib yam, muaj qee qhov sib txawv hauv qhov ntsuas, siv thiab thov. Cia peb ua tibzoo saib qhov sib txawv ntawm FC thiab FSF plywood.

Nws yog dab tsi?

Lo lus "plywood" los ntawm Fab Kis fournir (rau overlay). Nws yog tsim los ntawm gluing ua ke cov laug cam ntawm ntoo ntawm ntau yam tuab (veneer) . Rau qhov txiaj ntsig ntawm cov yam ntxwv siab dua ntawm lub zog thiab kev ntseeg tau, cov vaj huam sib luag tau glued thaum glued kom cov kev taw qhia ntawm cov fibers nyob ntawm txoj cai kaum rau ib leeg. Txhawm rau ua rau sab xub ntiag ntawm cov khoom siv zoo ib yam, feem ntau cov lej sib txawv yog txawv: peb lossis ntau dua.

Lub sijhawm no, feem ntau cov npe ntawm cov ntoo-laminated panels yog FC thiab FSF . Ob qho tib si thiab lwm yam sib txawv muaj lawv cov neeg txhawb nqa thiab cov neeg tawm tsam, uas niaj hnub sib cav txog cov khoom thiab kev nyab xeeb ib puag ncig ntawm cov phaj no. Cia peb sim nkag siab qhov teeb meem no.

Cia peb pib nrog txiav txim siab cov lus dab neeg

FC … Thawj tsab ntawv hauv lub npe yog ib qho rau txhua hom khoom siv no thiab txhais tau tias "plywood". Tab sis qhov thib ob hais txog kev sib xyaw uas tau siv thaum gluing cov vaj huam sib luag. Hauv qhov no, nws yog kua nplaum urea-formaldehyde.

FSF … Rau hom pawg thawj coj no, cov ntawv SF qhia tias cov khoom xws li phenol-formaldehyde cob tau siv los ua cov laug cam.

Tseem ceeb! Ntau yam nplaum nplaum cuam tshuam rau cov khoom ntawm plywood thiab, raws li, nws lub hom phiaj thiab siv.

Pom qhov sib txawv

Sab nraud, ob qho tib si ntawm cov tsiaj no sib txawv ntawm ib leeg. Rau kev tsim khoom ntawm ib qho thiab lwm qhov, tib hom veneer tau siv, tib txoj hauv kev ntawm kev sib tsoo thiab lamination ntawm sab xub ntiag tau siv. Tab sis tseem muaj qhov pom kev sib txawv. Lawv suav nrog qhov sib txawv hauv cov qauv hauv cov nplaum sib xyaw.

Hauv FC, cov kua nplaum tsis suav nrog cov khoom siv xws li phenol - hauv qhov no, nws yog qhov sib dua … Txij li txheej txheej ntawm cov kua nplaum thiab vaj huam sib luag tau ua tib xim, nws pom zoo ib yam li cov khoom siv. Cov nplaum sib xyaw rau FSF ntawm cov xim liab tsaus. Thiab los ntawm kev saib nws sab txiav, koj tuaj yeem ua kab ntawm cov ntoo thiab kua nplaum. Txawm tias tus txiv neej zoo ib yam hauv txoj kev, thaum ntsib nrog plywood thawj zaug, paub txog cov yam ntxwv no, yuav tuaj yeem paub qhov txawv ib hom ntawm cov khoom siv no los ntawm lwm qhov.

Sib piv cov khoom

Hauv paus, plywood boards sib txawv ntawm ib leeg.

Hws noo kuj

FC ruaj khov thiab muaj ntau yam txaus, tab sis nws tau npaj rau siv hauv qhov xwm txheej ntawm qhov tsis muaj dej noo . Nws yog tsim los ntawm cov ntoo tawv ntoo sib xyaw ua ke, tab sis kev sib txuas ntawm cov ntoo ntoo, alder thiab qee hom tsiaj kuj tseem tuaj yeem ua tau. Yog tias cov kua nkag mus rau hauv txheej txheej ntawm hom plywood no, kev hloov pauv thiab tawg yuav pib. Tab sis, txij li nws tus nqi qis, nws feem ntau siv hauv kev tsim kho sab hauv hauv chav, raws li txheej txheej rau hauv pem teb npog (parquet, laminate, thiab lwm yam), rooj tog thiab ntim ntim tau tsim los ntawm nws.

FSF, ntawm qhov tsis sib xws, yog noo noo tiv taus . Tom qab raug cov dej noo, piv txwv li, nag lossis daus hauv huab cua, nws tuaj yeem ntub tau, tab sis tom qab ziab, nws cov tsos thiab cov duab tsis hloov pauv.

Tseem, nws tsim nyog sau cia: yog tias cov plywood nyob hauv dej ntev, nws yuav o tuaj.

Lub zog

Hauv qhov kev hwm no, FSF hla nws "tus muam" los ntawm yuav luag ib nrab ib nrab (60 MPa thiab 45 MPa), yog li ntawd nws muaj peev xwm tiv taus cov khoom hnyav heev … Ntxiv rau, nws tiv taus cov khoom puas thiab hnav zoo dua.

Kev tiv thaiv ib puag ncig

Ntawm no FC tawm los rau saum , txij li tsis muaj phenol hauv cov qauv ntawm nws cov kua nplaum. Thiab FSF muaj nws ntau heev - 8 mg rau 100 g. Cov txiaj ntsig zoo li no tsis tseem ceeb rau tib neeg kev noj qab haus huv, tab sis nws tseem yuav muaj txiaj ntsig los saib xyuas nws thiab tsis siv hom plywood no hauv thaj chaw nyob, tshwj xeeb tshaj yog thaum npaj cov menyuam chav. Tom qab cov kua nplaum qhuav, nws dhau los ua qhov phom sij tsawg dua, tab sis thaum xaiv cov ntoo ua ntoo, koj yuav tsum xyuam xim rau qib ntawm kev tso tawm ntawm cov khoom phom sij.

Yog tias E1 tau qhia hauv cov ntaub ntawv rau cov khoom siv, tom qab ntawd nws muaj kev nyab xeeb heev thiab tuaj yeem siv sab hauv tsev. Tab sis yog tias E2 tsis tuaj yeem lees txais … Cov tshuaj lom hauv cov nplaum tuaj yeem tsim teeb meem thaum pov tseg. Lawv cuam tshuam tsis zoo rau ntawm daim tawv nqaij, cov hnoos qeev thiab lub cev ua pa. Yog li ntawd, cov seem tsis tas yuav raug hlawv, tab sis xa mus rau qhov chaw pov tseg.

Tshwm sim

Rau ob hom, nws yuav luag zoo ib yam, vim tib hom ntoo tau siv hauv kev tsim khoom. Kev dai kom zoo nkauj tsuas yog nyob ntawm qhov muaj lossis tsis muaj qhov tsis xws (pob, tsis suav nrog) ntawm sab xub ntiag.

Raws li txoj cai no, plywood tau muab faib ua qib kawm. Vim yog siv cov resins hauv FSF, qhov ua tsis tau yog pom tau pom meej dua.

Qhov twg yog qhov zoo dua los xaiv?

Ua ntej txiav txim siab xaiv ib lossis ob lub npe ntawm plywood, koj yuav tsum paub lawv thaj chaw ntawm kev thov. Muaj thaj chaw uas lawv sib tshooj thiab siv tau ob qho tib si, tab sis kuj tseem muaj thaj chaw uas tsuas yog ib qho ntawm lawv yuav ua haujlwm . Piv txwv li, FSF yog qhov zoo tshaj plaws thaum xav tau lub zog loj thiab tiv taus ya raws. Thiab FC yog qhov zoo tshaj plaws siv thaum muaj kev nyab xeeb ib puag ncig, zoo nkauj tsos thiab tus nqi yog qhov tseem ceeb.

FSF tawm ntawm kev sib tw thaum koj yuav tsum ua cov hauv qab no:

• formwork rau lub hauv paus;
• phab ntsa sab nrauv ntawm cov qauv tsev hom;
• vaj tse hauv tsev;
• rooj tog hauv tsev;
• cov chaw tshaj tawm;
• txheej rau cov ntaub ntawv vov tsev ntawm lub ru tsev.

FC tuaj yeem siv tau zoo ua cov khoom siv hauv cov xwm txheej hauv qab no:

• rau phab ntsa cladding, tshwj tsis yog chav ua noj thiab chav dej;
• ua ib txheej hauv pem teb;
• rau kev tsim cov rooj tog hauv tsev thiab thav duab, uas yuav nyob hauv thaj chaw (tsev, chaw ua haujlwm, thiab lwm yam);
• kev tsim cov thawv ntim khoom, ib yam khoom zoo nkauj.

Nws raug nquahu kom paub koj tus kheej nrog GOST 3916.2-96 kom paub cov yam ntxwv tseem ceeb thiab cov cim uas tau siv rau txhua daim ntawv plywood. Qhov kawg yuav qhia txog hom, qib, cov khoom sib xyaw ua ke ntawm cov khoom, nrog rau nws cov tuab, qhov loj me, hom ntoo veneer, chav tso pa tawm ntawm cov tshuaj phom sij, thiab nws tseem raug xuab zeb ntawm ib sab lossis ob qho tib si. Thiab ib qho ntxiv: thaum xaiv, teeb meem. PSF yog tus nqi ntau dua vim nws cov khoom. Tam sim no, paub txhua tus yam ntxwv, cov khoom thiab lub hom phiaj ntawm cov ntaub ntawv no, nws yuav tsis nyuaj rau kev xaiv qhov yog.
