Coniferous plywood: yam ntxwv, kev tsim, kos cim. Plywood PSF

Plywood yog ib lub tsev khoom tsim los ntawm cov txheej ntoo (veneer) koom ua ke.

Feature

Lub ntsiab ntawm plywood nyob ntawm seb ntawm qhov uas nws tau ua. Twb tau los ntawm lub npe nws yog tseeb tias coniferous plywood yog ua los ntawm coniferous tsiaj (spruce, Pine). Lub veneer cov khaubncaws sab nraud povtseg yog txheejtxheem kom cov fibers yog ib leeg rau ib leeg.

Yam ntxwv ntawm cov khoom:

• Tus nqi qis dua.
• Ib nyuag me me ntawm cov khoom.
• Withstands kub hloov.
• Moisture-pov thawj.
• Siab zog vim muaj cov txheej.
• Yooj yim rau siv (koj tuaj yeem pom, xyaum, thiab lwm yam).
• Absorbs suab nrov.
• Nws ua hauj lwm raws li ib txheej ntawm thermal rwb thaiv tsev.
• Ntoo impregnated nrog ntuj reins, uas ua rau cov khoom ua taus mus rau cov tsos ntawm puab thiab fungi.
• Sufficiently resistant rau kev txhoj puab heev.
• Aesthetically zoo nkauj vim yog tus qauv ntawm cov ntoo.

Txoj kev ua cov plywood

Muaj peb txoj hauv kev:

1. Sawing. Rau qhuav ntawm veneer, cov ntoo yog txiav mus rau hauv ib daim hlab mus txog 5 mm nyob rau hauv tuab. Nrog rau hom no, raw cov ntaub ntawv yog siv tsis tau nyiaj.
2. Planing - ib tug ntau txoj kev ywj pheej, uas tso cai rau muab ib tug veneer nrog ib tug tuab ntawm 3.5 mm.
3. Plywood grouting yog txoj kev los ntawm qhov uas cov veneers nrog lub thickness ntawm 1.2 rau 1.9 hli yog tau.

Cov plywood twg yog qhov zoo dua: nyooj los yog coniferous?

Yam li no yuav siv tau rau zus tau tej cov hom ntoo: ntoo thuv thiab hardwoods. Cov khoom ntawm cov khoom tau txais tos, ntawm chav kawm, nyob rau raw khoom. Txhua tus tsiaj muaj qhov zoo thiab qhov tsis zoo.

Plywood ntawm coniferous hom muaj ib tug me me ntawm txheej. Cov khoom ua los ntawm larch yog ntau ruaj, resilient thiab hnav-resistant. Rau cov khoom ntau ruaj nws yog zoo dua mus xaiv plywood los ntawm birch.

Veneer ua los ntawm birch muaj ib lub teeb tint thiab ib tug tsis zoo qauv qhia. Coniferous pob zeb, ntawm qhov tawm tsam, yog ib tsos tsaus tsawv thiab muaj tus qauv zoo nkauj zoo nkauj.

Coniferous ntoo yog impregnated nrog natural resins. Vim qhov no, cov ntaub ntawv ua los ntawm lawv tsis tshua pom cov pwm thiab cov hu ua fungi. Coniferous plywood yog khoom pheej yig hauv tsev.

Npav

Qhov zoo ntawm cov khoom nyob ntawm ntau ntawm cov kua nplaum uas siv los koom nrog cov veneer cov khaubncaws sab nraud povtseg. Nyob ntawm no, lub coniferous plywood muaj ob peb lub cim:

• Tus FBA yog hom qis tshaj plaws. Nws yog tsim los siv cov kua nplaum yas albuminasein. Qhov no ua rau nws yog ib tus phooj ywg zoo siv khoom. Tab sis cov ntaub ntawv no tuaj yeem tsis sawv ntsug ntawm qhov dej. Siv nws tsuas yog muaj kev tiv thaiv tawm tsam hauv dej.

• PSF - feem ntau nrov hom, ua nrog phenol-formaldehyde kua nplaum. Nws muaj zog txaus thiab tsis muaj dej yaug.

• FSF-TV sib txawv ntawm hom FSF impregnation nrog nplaim hluav taws xob. Vim li no, cov kab mob coniferous ntawm hom kab no muaj qhov uas tsis muaj kub nyob.

• FC yog tsim los ntawm kev pab ntawm urea kua nplaum, uas ua rau cov ntaub ntawv ntau hygroscopic. Siv rau lub chaw ua khoom ntawm rooj tog, ntim, sab hauv.

• FB yog moisture resistant, tsis raug rau txhoj puab heev cheeb tsam. Koj tuaj yeem siv nws txawm nyob hauv dej. Qhov no yog tiav los ntawm kev sib txuas cov txheej nrog bakelite kua nplaum thiab impregnation nrog tus qub vanish.

• BS - aircraft plywood, tau txais nws lub npe vim nws siv nyob rau hauv aviation thiab shipbuilding. Veneer yog glued ua ke nrog bakelite cawv-soluble kua nplaum. Coniferous plywood ntawm no kos yog waterproof, muaj zog, yoog raws thiab resistant rau txhoj puab ib puag ncig.

• BV muaj cov khoom qub tib yam li BS. Qhov tsuas yog txawv yog tias cov khoom ntawm no kos yog ntshai ntawm noo noo (nws yog nrog kev pab ntawm dej-soluble kua nplaum).

Txhua hom plywood txawv deg tiav. Nyob ntawm qhov no, nws tuaj yeem muaj peb hom: unpolished (NS), nrog ib tog sib tsoo (Sh1) thiab hauv av rau ob sab (Sh2).

FSF

Coniferous plywood FSF yog qhov nrov tshaj plaws nyob rau hauv kev tsim kho ntawm civil thiab industrial chaw. Nws tsis kam mus rau dej yog muab los ntawm impregnating txheej nrog tsis zoo soluble formaldehyde resins. Tom qab impregnation, cov veneer txheej yog lom nyob rau hauv xovxwm nyob rau hauv ib tug high kub.

Nws yog cai rau GOST cais tus nqi ntawm formaldehyde thiab phenol compounds. Qhov no ua rau nws nyuaj rau siv cov plywood hauv hauv thaj chaw.

Cov nplooj ntawv PSF plywood muaj qhov ntau thiab tsawg: 1.22 x 2.44 m, 1.25 x 2.50 m, 1.525 x 3.0 m, 1.525 x 1.525 m. Nyob rau tib lub sijhawm, lub thickness nws txawv ntawm 4-30 hli.

Lub plywood ntawm coniferous breeds ntawm kos FSF tau txais thoob plaws daim ntawv thov. Lub ntsiab lus tseem ceeb ntawm kev siv nws yog:

• Mus ib ntus hauv kev tsim kho.
• Sheathing ntawm cov khoom.
• Zoo li overlapping nyob rau hauv lub ru tsev.
• Thaum tsim tsheb, tsheb thiab nkoj rau lawv cov plating.
• Rau cov creation ntawm vaj teb thiab lub teb chaws rooj tog.
• Rau kev tsim kho ntawm cov ntaub ntawv (cov khoom yuav siv tau dua).
• Raws li raw cov ntaub ntawv rau cov khoom ntawm lwm cov ntaub ntawv.

Plywood yog ib qho khoom pheej yig thiab cov khoom siv zoo uas tau tsim nyob rau hauv kev ua lag luam ntev ntev.
