Txog kev tsim cov qauv hauv qab lub hauv paus, ntau yam ntaub ntawv tuaj yeem siv tau, tab sis laminated plywood tshwj xeeb tshaj yog xav tau. Nws yog ib lub tsev ntawv uas npog nrog zaj duab xis phenol-formaldehyde. Cov yeeb yaj kiab tau thov rau plywood ua rau nws tiv taus ya raws, tiv taus kev hloov pauv ntawm qhov kub ib puag ncig, thiab ruaj khov. Cov yeeb yaj kiab no ntsib cov plywood tau siv ntau yam kev lag luam, los ntawm kev tsim cov rooj tog mus rau kev tsim nkoj.

Kev piav qhia thiab yam ntxwv

Zoo plywood tau txais los ntawm nias ob peb (los ntawm 3 txog 10) cov nplooj ntoo ntoo (veneer) … Kev hloov pauv ntawm cov fibers hauv cov ntawv ua rau nws muaj peev xwm ua plywood cov khoom siv tau ruaj khov. Rau kev tsim kho thiab kho kom xav tau, plywood yog qhov tsim nyog, lub hauv paus uas yog pov tseg ntawm cov ntoo ntoo ntoo ua ntoo. Rau kev tsim cov rooj tog, plywood tau xyaum ua lub hauv paus ntawm coniferous veneer. Cov txheej txheem ntawm kev tsim cov yeeb yaj kiab ntsib plywood txawv los ntawm ib txwm muaj nyob rau theem ntawm kev npaj cov khoom siv raw . Cov nplaum suav nrog cov khoom siv uas ua rau nws muaj peev xwm txhawb nqa thiab ua yeeb yaj kiab rau txhua tus neeg vaj huam sib luag. Qhov no tso cai rau txhua feem ntawm cov laminate ua kua-nruj thoob nws tag nrho cov tuab.

Cov txheej sab nrauv muaj qhov ntom ntom ntawm 120 g / m2 . Ib qho ntxiv, cov xim ib txwm ntawm cov laminate muab rau hauv pem teb tsaus xim uas ua rau muaj kev rov tsim dua ntoo ntuj. Los ntawm kev ntxiv cov zas xim, koj tuaj yeem hloov xim ntawm plywood los ntawm lub teeb ci mus rau qhov tsaus ntuj heev. Raws li cov tuam txhab tsim khoom, cov plywood hauv tsev raws li GOST tsis muaj cov poplar suav nrog . Tab sis ua hauv Suav teb hauv nws cov qauv tuaj yeem muaj yuav luag 100% poplar sawdust. Cov khoom siv no yuav yog qhov zoo tshaj plaws, nws siv hauv txhua qhov kev lag luam tuaj yeem dhau los ua hom kev pheej hmoo.

Cov yam ntxwv khoom:

• dej cov ntsiab lus hauv cov khoom tsis ntau tshaj 8%;
• qhov ntsuas qhov ceev - 520-730 kg / m3;
• qhov sib txawv me me - tsis pub ntau tshaj 4 mm;
• tus nqi ntawm phenol-formaldehyde resins yog kwv yees li 10 mg rau txhua 100 g ntawm cov khoom.

Cov yam ntxwv no feem ntau lees txais rau txhua hom kev ua yeeb yaj kiab zoo ua ntsej muag plywood. Nws yog qhov nthuav kom nco ntsoov tias rau kev tsim cov ntawv tuab, siv cov veneers tsawg dua li rau cov ntawv nyias . Nyob rau tib lub sijhawm, 20mm tuab slab tau siv nruj heev rau kev tsim cov rooj tog zaum hloov pauv. Thiab cov nplais nrog cov tuab tuab 30 hli, tig mus, tau siv hauv kev ua haujlwm ntsig txog sab nrauv thiab kho kom zoo nkauj sab hauv.

Raws li TU tau tsim, lub tsev txiav ntoo ntawm lub vaj huam sib luag yuav tsum tau ua nruj me ntsis ntawm kaum ntawm 90 °. Tso cai sib txawv raws qhov ntev ntawm lub vaj huam sib luag tsis ntau tshaj 2 hli rau ib txoj kab ntsuas kab. Ntawm ntug, qhov muaj cov kab nrib pleb thiab nti yog qhov tsis tuaj yeem lees txais.

Cov khoom tig los

Qhov kev txhais no cuam tshuam txog tus naj npawb ntawm cov voj uas plywood tuaj yeem tiv taus thaum siv rov siv tau. Lub sijhawm no, muaj kev faib cov khoom raws li cov pawg raws li cov chaw tsim khoom.

• Cov ntawv ua hauv Suav teb . Feem ntau xws li cov plywood muaj cov yam ntxwv tsis zoo, cov ntawv tuaj yeem tiv taus tsis pub ntau tshaj 5-6 zaug.
• Cov phaj tsim los ntawm cov tuam txhab Lavxias feem ntau , tau suav tias yog kev daws teeb meem zoo ntawm tus nqi thiab ua haujlwm ntev. Raws li hom khoom, cov khoom tuaj yeem siv tau los ntawm 20 txog 50 cycles. Qhov sib txawv no yog los ntawm kev siv thev naus laus zis thiab cov cuab yeej siv.
• Plywood tsim tawm ntawm cov chaw tsim khoom loj hauv tsev thiab txawv teb chaws los ntawm Tebchaws Europe (tshwj xeeb, Finland), yog qeb raws li qhov ua tau zoo, uas cuam tshuam rau nws cov nqi. Nws tuaj yeem tiv taus txog 100 mus.

Kev siv rov qab los cuam tshuam tsis yog los ntawm ib lub chaw tsim khoom, tab sis kuj los ntawm kev ua tiav ntawm cov xwm txheej tsim nyog ntawm kev siv.

Pros thiab cons

Qhov zoo ntawm kev siv zaj duab xis ntsib plywood yog:

• ya raws tsis kam;
• siab tsis kam khoov los yog ncab;
• qhov muaj peev xwm rov siv tau yam tsis poob ntawm tus yam ntxwv thawj;
• qhov loj me ntawm cov ntawv sib txuam;
• siab hnav tsis kam.

Qhov tsawg

• tus nqi siab (txhawm rau txuag nyiaj txiag, koj tuaj yeem siv xauj lossis yuav cov khoom siv);
• lom cov pa phem ntawm phenol-formaldehyde resins (nws tsis muaj teeb meem hauv kev tsim cov qauv).

Ntau yam

Cov tuam txhab tsim ntau hom plywood:

• zoo tib yam kab nrog zaj duab xis;
• kua nplaum FC (plywood, urea kua nplaum);
• nplaum FSF (plywood, phenol-formaldehyde kua nplaum);
• kev tsim kho.

FC tau xyaum ua haujlwm sab hauv tiav lossis thaum tsim cov rooj tog zaum. Rau kev tsim kho lub hauv paus, phab ntsa lossis hauv pem teb, hom no tsuas yog siv tshwj xeeb thaum tsim cov txheej txheem ruaj khov, lossis yog tias nws tsis siv ntau dua 3-4 mus.

Nrog cov lej loj dua, nws tsis muaj peev xwm siv nws, vim nws poob nws cov teeb tsa thiab lub zog muaj zog.

Rau kev tsim kho cov qauv txheej txheem, zoo ib yam, FSF lossis kev tsim kho plywood kab nrog zaj duab xis tau siv. Qhov kev xaiv nyob ntawm seb hom tsev tau tsim thiab lub zog ntawm cov pob zeb cuam tshuam rau cov phab ntsa formwork. Kev tsim plywood muaj zog dua, ruaj dua thiab ruaj khov dua . Yog siv kom raug, cov khoom siv no tuaj yeem siv ntau zaus.

Kev hloov pauv ntawm cov ntawv uas tau lo nrog zaj duab xis rau kev ua haujlwm tuaj yeem ncav ntau dua 50 mus yog tias nws yog kev tsim plywood, uas suav tias yog qhov txiaj ntsig zoo. Qhov kev hloov pauv tau cuam tshuam ntau los ntawm hom ntoo siv hauv kev tsim cov khoom siv thiab lub tebchaws ntawm keeb kwm. Yog li, birch plywood muaj cov yam ntxwv zoo tshaj plaws, ua raws li cov ntoo poplar thiab tom qab ntawd ntoo ntoo coniferous.

Qhov ntev (kho kom raug)

Ntawm Lavxias kev ua lag luam ntawm cov khoom siv hauv tsev, koj tuaj yeem pom cov duab hauv qab no ntawm cov yeeb yaj kiab ua haujlwm plywood ntsib: 6; cuaj; 12; kaum tsib; 18; 21; 24 hli tuab. Txhawm rau txhim kho daim ntawv thaum lub sijhawm tsim cov pob zeb sib xyaw ua ke, 18 thiab 21 hli lub tsev tsim cov ntawv tau siv, nyob rau qhov kawg ntawm qhov uas siv cov kua roj vanish raws li acrylic tiv thaiv kom ntub dej. Panels thinner dua 18mm muaj cov tshuaj phom sij tsawg heev, thaum 24mm slabs yog kim dua.

Plywood, laminated for formwork nrog qhov ntev ntawm 2500 × 1250 × 18 mm, 2440 × 1220 × 18 mm, 3000 × 1500 × 18 mm - tshwj xeeb tshaj yog xav tau vim tus nqi qis . Thaj chaw ntawm lub vaj huam sib luag ntsuas 2440 × 1220 × 18 mm yog 2.97 m2 nrog qhov hnyav ntawm 35.37 kg. Lawv tau ntim rau hauv pob ntawm 33 lossis 22 daim. Thaj tsam ntawm lub vaj huam sib luag 2500 × 1250 × 18 hli yog 3.1 m2, thiab qhov hnyav yog kwv yees li 37 kg. Ib daim ntawv nrog tuab 18 hli thiab qhov loj ntawm 3000x1500 muaj thaj tsam ntawm 4.5 m2 thiab hnyav 53 kg.

Cov Lus Qhia Xaiv

Yog tias koj xav tau yuav plywood rau kev ua haujlwm, tom qab ntawd thaum xaiv cov laug cam, them nyiaj tshwj xeeb rau cov hauv qab no

• Nqe … Tus nqi qis heev qhia tias cov khoom lag luam tsis zoo, yog li ntawd, nws raug nquahu kom yuav cov khoom lag luam ntawm cov hauv paus thiab hauv khw muag khoom kho vajtse loj.
• Cov qauv nto . Cov ntawv yuav tsum tsis txhob muaj qhov tsis xws luag thiab puas tsuaj. Yog tias cov ntaub ntawv tau khaws cia nrog kev ua txhaum, ces nws yuav muaj qhov cuam tshuam, uas nyuaj heev rau kho. Nws tau xav tias tiav cov plywood feem ntau yog xim av thiab dub.
• Npav … Cov ntawv teev npe ua rau nws muaj peev xwm nrhiav pom qhov tseem ceeb ntawm cov khoom siv ntawm qhov chaw. Cov ntaub ntawv raug luam tawm ntawm daim ntawv lo lossis cov ntawv sau rau ntawm cov khoom nws tus kheej.
• Qib … Cov khoom siv hauv tsev tau tsim tawm hauv ntau qib - ntxiv, I -IV. Qib siab dua cov ntaub ntawv tsim khoom muaj, qhov nyuaj dua nws yuav tsum tau txais, vim tias tus nqi qis kawg yuav siab heev. Txawm li cas los xij, tib lub sijhawm, qib I / II cov vaj huam sib luag yuav muaj lub zog zoo tshaj plaws thiab cov yam ntxwv ua tau zoo. Vim li ntawd, cov khoom siv hauv tsev rau kev ua haujlwm raug xaiv raws li qhov xwm txheej ntawm kev siv thiab thauj khoom.
• Muaj daim ntawv pov thawj … Cov khoom lag luam cuam tshuam nrog tshwj xeeb, hauv qhov no, cov chaw tsim khoom yuav tsum raug kuaj thiab tau txais daim ntawv pov thawj sib xws. Lub xub ntiag ntawm cov ntaub ntawv lees paub qhov ua tau zoo ntawm cov khoom lag luam nrog cov txheej txheem kev tsim lossis GOST yog lub cim tseem ceeb ntawm qhov tsim nyog tsim nyog ntawm cov khoom, ntxiv rau, daim ntawv yuav tsum tau ntim nrog lub foob tiag lossis lub thwj cim ntawm lub koom haum lees paub nws authenticity, daim ntawv theej yuav tsis ua haujlwm.

Rau qhov tsis xaiv qhov yuam kev, txhua yam khoom tshwj xeeb yog cuam tshuam nrog cov yam ntxwv xav tau rau kev ua haujlwm.
