Yuav ua li cas siv plywood bakelized?

Rov qab nyob rau hauv 1909 tau sau npe rau hauv lub ntiaj teb no tus thawj patent rau qhov siv thiab ua yas. Thaum xub thawj, tej zaum tsim ib tug phenol-formaldehyde cob, thiab tsuas yog tom qab lawv tau txais hauv lub ntiaj teb no tus thawj polymer. Ua ntej, ib tug tshiab tshuaj tau magnificently hu ua los ntawm chemists "oksibenzilmetilenglikolangidrid", tab sis txiav txim siab zoo prevailed, thiab ces twb yug los rau hauv lub "bakelite". Ua tau, hnub no yog hnub thaum muaj ib tug plywood bakelized.

Txawm li cas los, qhov nrov tshiab tej yam khoom uas yog tsis tam sim ntawd: chiv nws siv heev dua lwm yam rau zus tau tej cov insulators. Tab sis tom qab ib tug ob peb xyoos, nws kos cov xim ntawm cov neeg sawv cev los ntawm lub tsheb thiab rooj tog zaum industries: bakelite yog tsis tshua malleable thiab pheej yig khoom, zoo tagnrho rau cov loj ntau lawm.

Twb tsim tsocai plywood bakelized, uas yog yuav luag unchanged tshwm sim rau hnub no. Nws yog raws li nyob rau hauv high-zoo birch veneer, glued phenol formaldehyde cov kua roj vanish. Muab lub siab thiab kub, uas yog qhov tseem ceeb rau cov neeg mob rau zus tau tej cov no cov ntaub ntawv uas, nws yog tau mus cuag ze li ntawm 100% degree ntawm impregnation. Phenols lawv tus kheej yog insoluble thiab yuav tsis ua mob rau cov kev kho mob ntawm tus neeg, tab sis yog zoo nyob rau hauv kev tiv thaiv fungal nres ntawm plywood. Vim li no, cov nyhuv tib yam yog yuav luag tsis rot.

Nyob rau hauv cov kev phem ntawm cov huab simplicity ntawm ntau lawm, yielding plywood bakelized muaj lub dag lub zog yam ntxwv uas yuav pab tau nws mus rau yuav luag sib tw nrog lub tseeb uas. Tab sis nws tus nqi yog tsawg, uas muaj txhawb mus rau lub chaw ntawm no cov ntaub ntawv uas cov builders.

Yog hais tias koj nyeem kom zoo zoo, tej zaum koj yuav tsis ua tau rau koj cov xov xwm ntawm lub fact tias nws muaj peev xwm yuav siv tau txawm nyob rau hauv lub feem ntau nyuaj tej kev kawm.

Vim li no, nws feem ntau yuav pom nyob rau hauv xws txawv qhov chaw, uas yog lub lawj ntawm lub nkoj. Ntawm cov hoob kawm, nyob rau hauv tej yam, ib tug tshwj xeeb dej-resistant plywood bakelized lub sij hawm ntev tau mas txawm muaj tej yam uas reactive seawater.

Nws kuj yuav siv tau raws li cov ntaub ntawv uas rau lub reusable formwork, raws li txawm tias ib tug ob peb casting mus khaws cia nws tsis muaj teeb meem. Sau xws shuttering yog yooj yim, thiab nws tus phab ntsa cia kom tau cov zis hau ze li ntawm zoo meej configuration. Xav kuj tsis tshua muaj thermal conductivity, koj yuav poob ntau tsawg tshav kub, siv lub cuab yeej ntawm lub caij ntuj no cua kub qhob thaum pouring. Nyob rau hauv luv luv, ib tug yooj yim plywood bakelized cawm tau ib tug ntau ntawm cov nyiaj nyob rau tus nqi qis tshaj yuav nws.

Cov loj loj ntawm ib tus qauv ntawv ntawm no cov ntaub ntawv uas eliminates qhov xav tau rau ib tug tsawg kawg nkaus naj npawb ntawm cov pob qij txha. Yog hais tias zoo zoo thiab ua tib zoo siv, ib tug formwork heev tau mas hais txog peb caug ntsaws! Tam sim no plywood bakelized hom FBS ua nyob rau hauv peb lub teb chaws. Nws tso tawm ntawm cov nroj tsuag nyob rau hauv koom Tyumen thiab Nizhny Novgorod, paub siab zoo ntawm lawv cov khoom.
