Txawm hais tias qhov kev tsim kho kev lag luam muaj ntau yam khoom siv, tseem muaj qee qhov uas tseem xav tau txog niaj hnub no. Cov no suav nrog plywood. Cov khoom siv no muaj ntau yam kev siv thiab muaj lub cev thiab txuj ci zoo heev. Ib qho tseem ceeb tshaj plaws ntawm cov plywood, uas txiav txim siab nws qib thiab qhov zoo, yog qhov ntsuas ntom ntom. Nws yog qhov ntsuas no uas yuav tham txog hauv kab lus no.

Peculiarities

Plywood yog cov khoom siv sib xyaw ua ke, rau kev tsim khoom uas ntau hom ntoo tau siv. Nws suav nrog ntau txheej txheej ntawm veneer, uas txuas nrog cov nplaum tshwj xeeb. Zoo li lwm yam khoom siv hauv tsev, plywood muaj qee yam khoom. Nws yog tus yam ntxwv los ntawm:

• lub zog;
• kev phooj ywg zoo;
• nplaim taws;
• ya raws tsis kam;
• zoo heev insulating zog, cov uas nws muaj nqis sau thermal conductivity thiab ya raws permeability.

Tab sis qhov tseem ceeb tshaj plaws uas cov neeg siv khoom tau them nyiaj mloog thaum yuav thiab siv cov khoom no yog nws qhov ntom ntom. Qhov nqus tshwj xeeb ntawm plywood yog qhov piv ntawm qhov hnyav ntawm cov khoom siv rau nws ntim. Nws nyob ntawm seb hom veneer ntoo twg cov khoom siv tau tsim los ntawm. Cov txheej txheem tsim cov ntawv raug tswj los ntawm cov ntaub ntawv tswj hwm: GOST 3916.1-96, 3916.2-96, 11539-83. Lawv qhia qhov tso cai tus nqi ntawm qhov ntom ntawm cov khoom - los ntawm 300 kg ib m³ rau 700 kg ib m³.

Ceev ntawm ntau hom plywood

Raws li hom ntoo, plywood tau muab cais ua hom, txhua tus yog tus yam ntxwv tshwj xeeb. Cia peb ua tibzoo saib ntawm txhua hom.

Birch

Cov ntoo no muaj lub zog siab, yog li plywood los ntawm nws muaj lub cev zoo thiab cov yam ntxwv tsis zoo, yog rau qib siab. Cov nplaim ntawm cov khoom yog du thiab zoo nkauj. Qhov nqus tshwj xeeb ntawm cov ntoo veneer cov khoom sib txawv los ntawm 640 kg / m³ txog 700 kg / m³. Lub peev xwm ntawm cov khoom siv no yog dav thiab sib txawv. Nws yog siv los ntawm:

• rau kev tsim khoom ntawm cov qauv monolithic, piv txwv li, kev ua haujlwm;
• nyob rau hauv tus txheej txheem ntawm kev npaj cov plag tsev;
• rau phab ntsa thiab qab nthab cladding.

Birch plywood yog qhov zoo tagnrho rau lub zog ua haujlwm siab.

Laminated

Nov yog ib qho ntawm cov neeg nyiam tshaj plaws thiab nquag siv. Qhov tshaj plaws yog tias daim ntawv tsis yog tsuas yog veneer, tab sis kuj yog txheej tiv thaiv ntawm laminate. Cov khoom muaj cov yam ntxwv zoo thiab cov khoom zoo. Nws yog tus yam ntxwv ntawm lub tshuab muaj zog thiab ntom ntom, uas yog los ntawm 640 kg / m³ txog 700 kg / m³.

Zaj duab xis ntsej muag plywood tuaj yeem siv tau:

• rau kev tsim cov formwork ntawm cov chaw tsim kho;
• nyob rau hauv tus txheej txheem ntawm kho kom zoo nkauj sab hauv;
• rau kev npaj cov menyuam yaus thiab chaw ua kis las;
• rau kev teeb tsa laj kab thiab cov ntawv tshaj tawm;
• rau kev tsim cov khoom ntim khoom;
• rau npog cov tsheb vans.

Cov khoom siv yog ua los ntawm kev hnav tsis kam, qib siab ntawm kev tiv thaiv ya raws, yooj yim ntawm kev teeb tsa thiab ua tiav.

Coniferous

Hom kab no yog tsim los ntawm cov ntoo coniferous. Txij li thaum lawv muaj ntau cov cob, plywood yog cov dej noo tiv taus thiab siv tau tsis rot. Qhov ntom ntawm cov ntoo plywood yog kwv yees li 550 kg / m³.

Qhov dav ntawm cov khoom siv no yog dav heev:

• txhim kho cov thav duab thiab cov tsev qis thiab cov tsev qis;
• tsheb thiab kev tsim nkoj - plywood sheaths lub hulls ntawm cov nkoj, tsheb, txhim kho phab ntsa thiab npog hauv pem teb;
• cov rooj tog tsim khoom - cov khoom siv zoo tshaj plaws rau kev tsim cov rooj tog hauv txee.

Tsis tas li, plywood coniferous tau siv rau kev kho kom zoo nkauj phab ntsa, tsim kom muaj cov khoom zoo nkauj sab hauv tsev, thiab ua cov ntawv rov ua dua tshiab rau cov chaw tsim kho.

FC

FC - plywood nrog qib nruab nrab ntawm kev tiv thaiv ya raws, uas yog siv tshwj xeeb rau kev ua haujlwm sab hauv. Cov khoom lag luam muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom - 660 kg ib m3. Nws yog siv hauv kev tsim kho, rooj tog kev lag luam. Tsis tas li, cov khoom siv rau kev ua tiav rau tsheb, kev lag luam thiab khoom siv nthuav tawm.

Qhov twg los xaiv?

Thaum xaiv plywood, thiab nws cov khoom sib txawv muaj ntau yam niaj hnub no, nws yog qhov yuav tsum tau coj mus rau hauv tus account kiag li txhua yam khoom, yam ntxwv thiab tsis. Txhawm rau txiav txim siab qhov xav tau ceev, koj yuav tsum xav txog:

• rau lub hom phiaj twg cov khoom yuav khoom;
• nyob rau hauv huab cua zoo li cas nws yuav siv;
• load uas yuav tiv taus.

Nyuam qhuav pib hauv tsab xov xwm, peb tau tham ntxaws ntxaws txog hom khoom lag luam twg thiab muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom nyob hauv txhua tus ntawm lawv, nrog rau hais txog thaj tsam ntawm kev thov cov khoom nrog ib lossis lwm qhov ntsuas qhov ntom. Yog tias koj muaj lus nug, koj tuaj yeem sab laj nrog kws tshaj lij, piv txwv li, hauv khw muag khoom kho vajtse qhov kev yuav khoom.

Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov nqus tshwj xeeb ntawm cov khoom tau cuam tshuam tshwj xeeb los ntawm hom ntoo. Tab sis cov khoom sib xyaw ua ke, nrog kev pab uas txheej txheej veneer txuas nrog, tsis muaj dab tsi ua nrog kev tsim ntawm qhov ntsuas no.
