Rau cov neeg yuav khoom B2B tab tom nrhiav kom txhawb nqa lawv cov nyiaj rov qab los ntawm kev nqis peev, tus nqi ib lub ncuav yog qhov tseem ceeb tshaj li tus nqi pib ntawm cov plywood. Thicker, siab -zooreusable qhob formwork panelsua nrog hwm eucalyptus cores thiab ntom phenolic overlays tuaj yeem rov qab siv tau txog 20 mus rau 30 zaug yog tias tuav thiab tswj kom zoo. Thicker panels (xws li 17mm thiab 19mm) yog lub cev muaj zog ntau dua rau kev puas tsuaj los ntawm cov pob zeb vibrators, cov cuab yeej stripping, thiab qhov chaw tuav. Tshaj ib txoj haujlwm ntau-theem, yuav tus nqi them, tuab F17 vaj huam sib luag uas tau txais ntau qhov rov qab siv dua yog qhov pheej yig dua li kev yuav ib qho thinner, qis -qib lwm qhov uas warps tom qab tsuas yog peb lossis plaub lub ncuav.

Kev sib piv: F17 Formply vs Structural Plywood

Ib qho kev tsis sib haum xeeb rau cov neeg yuav khoom thoob ntiaj teb yog qhov sib txawv ntawm cov pob zeb tshwj xeeb formwork panels thiab cov qauv txheej txheem. Txawm hais tias ob qho tib si cov ntaub ntawv tuaj yeem sib faib cov qauv kev ntxhov siab nyob rau hauv Oceania lub moj khaum, lawv qhov kev ua tau zoo hauv qhov chaw ntub dej sib txawv heev. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb los tiv thaiv kev xaiv cov khoom puas tsuaj ntawm qhov chaw ua haujlwm.

Lub luag hauj lwm ntawm Deg Overlays thiab Moisture Protection

Thaum soj ntsuamf17 formply vs structural plywood, qhov pom tseeb tshaj qhov sib txawv nyob ntawm qhov chaw. F17 tsim muaj lub siab- ntom ntom (HDO) phenolic zaj duab xis, feem ntau yog 120g / m² lossis 220g / m², uas yog thermally fused rau sab nrauv veneers. Cov yas glossy no- zoo li thaiv thaiv cov ntoo fibers los ntawm kev nqus dej los ntawm cov pob zeb ntub dej. Cov txheej txheem plywood tsis muaj qhov teeb meem no, txhais tau hais tias yog tias nws siv rau formwork, nws yuav sai sai nqus dej noo, o, plam nws cov qauv nruj, thiab daim ntawv cog lus mus tas li rau cov pob zeb, ua rau stripping yuav luag tsis muaj kev puas tsuaj rau lub ntsej muag ntoo.

Core Void Tolerances thiab Shear Strength

Raws li AS6669 specification,AS 6669 uamuaj kev txwv nruj dua ntawm cov tub ntxhais hauv cov voids thiab overlaps piv rau cov qauv vaj huam sib luag. Lub vaj huam sib luag vaj huam sib luag tuaj yeem zam qhov sib txawv me me ntawm cov pob qij txha veneer, tab sis hauv formwork, cov voids sawv cev rau cov ntsiab lus tsis muaj zog. Nyob rau hauv lub siab heev ntawm lub pob zeb nchuav, cov cheeb tsam nrog cov voids sab hauv tuaj yeem tawg mus rau sab hauv, ua rau cov dimples hauv cheeb tsam ntawm cov pob zeb los yog tag nrho cov vaj huam sib luag shear tsis ua haujlwm. F17 tiag tiag tau dhau los ua cov txheej txheem zoo sib xws thiab ntug- sealing nrog cov xim acrylic tsis muaj dej kom ntseeg tau tias cov dej tsis tuaj yeem nkag mus rau hauv cov plies sab hauv, tiv thaiv cov qauv kev ncaj ncees ntawm tag nrho lub rooj sib txoos thoob plaws hauv nws lub neej ua haujlwm.

Kev coj ua zoo tshaj plaws rau kev tuav F17 Formply Panels ntawm qhov chaw

Txawm hais tias qhov thickness koj yuav, lub neej ntawm kojhardwood formwork plywoodyog ncaj qha khi rau yuav ua li cas nws yog kho ntawm qhov chaw tsim kho. Thaum tau txais cov vaj huam sib luag, lawv yuav tsum tau muab khaws cia ncaj nraim, tawm hauv av, thiab npog nrog cov ntaub thaiv dej kom tiv thaiv lawv ntawm tshav ntuj ncaj qha thiab los nag. Thaum cov vaj huam sib luag raug txiav kom loj rau ntawm - qhov chaw kom haum rau qhov tshwj xeeb nkag mus, cov npoo ntawm cov ntoo tshiab tshiab yuav tsum tau muab rov qab tam sim nrog cov qib siab - zoo, dej- cov xim acrylic. Ua tsis tiav cov npoo no yuav tso cai rau cov dej ntub dej rau hauv cov tub ntxhais, ua rau thaj tsam tuab o (thickness edge- o), uas ua rau cov kab sib txuas tsis sib haum ntawm cov pob zeb txuas ntxiv tom ntej.

Tsis tas li ntawd, siv tus kws tshaj lij- qib tso tawm tus neeg sawv cev (daim ntawv roj) ua ntej txhua lub ncuav yog qhov tseem ceeb, txawm tias phenolic zaj duab xis ib txwm tiv thaiv kev sib txuas. Tus neeg sawv cev tso tawm txo qis qhov kev sib txhuam ntawm lub cev thaum lub sij hawm stripping txheej txheem, tiv thaiv cov pob zeb los ntawm tearing lub ilv txheej txheej zaj duab xis nyob deb ntawm lub hardwood veneer. Thaum stripped, cov panels yuav tsum tau muab ntxuav tam sim ntawd nrog ib tug tsis yog - metallic scraper tshem tawm tej qhob qhob qhob paste, stacked zoo, thiab kom deb ntawm dej sawv. Los ntawm kev tswj hwm cov txheej txheem kev saib xyuas no, B2B cov thawj coj yuav tuaj yeem lav tias lawv cov peev txheej hauv hwm F17 vaj huam sib luag muab qhov siab tshaj plaws ntawm kev rov siv dua, txo qis tag nrho cov nqi tsim kho ib square meter.
