5 Ntshuam Qhov Tseeb Koj Yuav Tsum Paub Txog Zaj Duab Xis Taub Hau

Dab tsi yog plywood?

Plywood tuaj yeem muab faib ua plywood mos (masson ntoo thuv, larch, liab ntoo thuv, thiab lwm yam) thiab hardwood plywood (bass ntoo, birch, tshauv, thiab lwm yam).

Los ntawm qhov kev xav ntawm dej tsis kam, plywood tuaj yeem muab faib ua plaub pawg:

Chav Kawm I - Huab cua resistant thiab boiling dej resistant plywood (WBP), siv phenolic resin nplaum.Haum rau thaj chaw sab nraum zoov xws li aviation, ships, carriages, ntim, qhob formwork, hydraulic engineering, thiab lwm qhov chaw uas muaj dej tsis kam thiab kev nyab xeeb.

Class II noo noo resistant plywood (MR), muaj peev xwm ntawm lub sij hawm luv luv dej txias raus dej, haum rau siv sab hauv tsev nyob rau hauv ib txwm tej yam kev mob.Ua los ntawm kev sib txuas nrog cov ntsiab lus qis urea formaldehyde resin lossis lwm cov nplaum nrog cov khoom sib npaug.Siv rau rooj tog, ntim khoom, thiab kev tsim kho vaj tsev lub hom phiaj.

Chav Kawm III dej resistant plywood (WR), uas tuaj yeem tsau rau hauv dej txias, tuaj yeem tiv taus lub sijhawm luv ntawm cov dej kub immersion, thiab muaj cov kab mob tua kab mob, tab sis tsis tiv taus kub.Nws yog ua los ntawm urea formaldehyde resin lossis lwm cov nplaum nrog cov khoom sib npaug.Siv rau kev kho kom zoo nkauj sab hauv thiab ntim cov tsheb thauj khoom, nkoj, rooj tog zaum, thiab cov tsev.

Chav Kawm IV uas tsis yog noo noo resistant plywood (INT), siv nyob rau hauv tsev nyob rau hauv ib txwm tej yam kev mob, muaj ib tug tej yam kev sib raug zoo zog.Ua los ntawm kev sib txuas nrog taum kua nplaum lossis lwm cov nplaum nrog cov khoom sib npaug.Feem ntau yog siv rau kev ntim khoom thiab lub hom phiaj dav dav.Lub thawv tshuaj yej yuav tsum tau ua los ntawm taum kua nplaum plywood

Cov plywood siv rau cov pob zeb formwork zaj duab xis ntsib plywood yog nyob rau hauv chav kawm I plywood nrog huab cua thiab dej tsis kam, thiab cov nplaum yog Phenolic resin nplaum yog tsuas yog ua los ntawm poplar, birch, ntoo thuv, eucalyptus thiab lwm yam.

1. Zaj duab xis ntsib marine plywood qauv thiab specifications

(1)Qauv

Cov ntoo plywood siv rau formwork feem ntau yog tsim los ntawm khib khaubncaws sab nraud povtseg xws li 5, 7, 9, thiab 11, uas yog sib koom thiab kho los ntawm kub nias.

Hom.Cov lus qhia kev ntxhib los mos ntawm cov khaubncaws sab nraud povtseg yog perpendicular rau ib leeg, thiab feem ntau qhov kev ntxhib los mos ntawm lub rooj tsavxwm sab nrauv yog sib npaug mus rau qhov ntev ntawm cov plywood nto.Yog li ntawd, cov kev taw qhia ntev ntawm tag nrho cov plywood muaj zog, thiab cov kev taw qhia luv luv tsis muaj zog.Kev ceev faj yuav tsum tau them thaum siv nws.

(2) Specifications

Specifications thiab qhov ntev ntawm zaj duab xis ntsib plywood rau formwork

2. Zaj duab xis ntsib plywood bonding kev ua tau zoo thiab bearing muaj peev xwm

(1) Kev sib koom ua ke

Cov nplaum rau plywood siv nyob rau hauv zaj duab xis ntsib marine plywood yog tsuas yog phenolic resin.Hom nplaum no muaj kev sib raug zoo zog thiab dej tsis kam, zoo heev kub thiab corrosion kuj, nrog zoo heev boiling dej kuj thiab durability.

Bond Strength Index Values ​​for Film Faced Marine Plywood

Thaum muas plywood rau pob zeb formwork, koj yuav tsum xub xyuas seb nws puas yog Class I plywood,

Tshawb xyuas seb cov plywood puas tau siv phenolic resin nplaum los yog lwm cov nplaum nrog cov khoom sib npaug.Yog tias kuaj tau thaum cov xwm txheej raug txwv thiab kev ntsuas kev sib txuas tsis tuaj yeem ua tau, cov khoom me me tuaj yeem ua tau sai thiab yooj yim sib txawv ntawm cov dej kub npau npau.

Siv ib daim me me ntawm 20 hli square sawn los ntawm plywood thiab boiled nyob rau hauv boiling dej rau 2 teev.Siv phenolic resin raws li daim ntawv xeem yuav tsis tev tawm tom qab ua noj, thaum lub xeem daim ntawv siv mem tes formaldehyde resin raws li cov nplaum yuav tev tawm tom qab ua noj.

(2) Bearing muaj peev xwm

Lub peev xwm load-bearing ntawm ntoo plywood muaj feem xyuam rau nws cov thickness, zoo li qub bending zog, thiab elastic modulus

Txheem qhov tseem ceeb ntawm qhov zoo li qub bending zog thiab elastic modulus ofshuttering plywood (N / mm2)

Lub tsev cpncrete shuttering plywood tuaj yeem muab faib ua qhov zoo tib yam shuttering plywood thiab zaj duab xis ntsib plywood.

Lub tiaj shuttering plywood nto yog kho nrog phenolic resin nrog muaj zog waterproofing.Thaum muab cov pob zeb ua ke siv lub tiaj shuttering plywood xws li koov choj, kab teeb, thiab kab, tsuas yog tus qauv nruj thiab cov lej yuav tsum tau ntsib, thiab tom qab ntawd kho kom zoo nkauj grey yuav tsum tau siv rau hauv nto.Feem ntau siv nyob rau hauv pej xeem thiab kev lag luam vaj tse.

Zaj duab xis ntsib marine plywood yog tsim los ntawm npog ib txheej ntawm laminnation daim ntawv ntawm ib tug zoo khoom vaj huam sib luag .Qhov saum npoo ntawm zaj duab xis ntsib plywood yog du, ci, waterproof, thiab fireproof, nrog zoo heev durability (weather resistance, corrosion resistance, chemical resistance) thiab muaj zog tiv thaiv fouling muaj peev xwm.

Yog vim li caszaj duab xis ntsib plywoodkim heev piv rau tej yamshuttering plywoodformwork?

1. Cov ntawv tooj liab txawv teb chaws uas laminated ntawm lub plywood muaj cov yam ntxwv ntawm kev du, zoo flatness, thiab yooj yim demolding.Tom qab demolition, qhov saum npoo ntawm cov pob zeb yog du, zam kev pleev xim rau theem nrab, txo cov nqi, thiab siv sijhawm luv luv.Nws yog tus cwj pwm los ntawm lub teeb yuag, kev txiav ruaj khov, kev tsim kho zoo, thiab kev tsim kho ceev ceev.

2. Zaj duab xis ntsib plywood yog cov khoom siv high-temperature thiab high-pressure composite, uas yog ntom, siab zog, thiab muaj zog toughness.Lub zog static dabtsi yog khoov yog ntau tshaj ob zaug ntawm ntoo.

3.) Muaj zog tiv thaiv dej.Thaum lub sij hawm tsim khoom, ib txheej ntawm phenolic resin yog siv rau ib txheej ntawm kub nias molding yam tsis boiling cov kua nplaum rau 5 teev, ua rau nws nyuaj rau deform lub vaj huam sib luag thaum lub sij hawm ua vaj tse.

4.) Lub thermal conductivity yog me dua li ntawm cov pwm steel, uas yog qhov zoo rau kev kub siab rau lub caij ntuj sov thiab lub caij ntuj no.

5. Lub turnover tus nqi yog siab dua li ntawm dav shuttering plywood, thiab tag nrho cov turnover tus nqi yuav ncav cuag 12-18 zaug.
