Kev Ua Haujlwm Yuav Tsum Tau Ua Rau Kho Kom Zoo Nkauj Veneer Veneer Plywood

① Lub teb chaws tus qauv tau teev tseg tias qhov ntsuas dej noo ntawm cov khoom siv veneer veneer plywood yog 6 feem pua ​​​​rau 14 feem pua.

② Lub zog ntawm qhov sib txuas ua ke qhia txog kev sib koom ua ke ntawm cov txheej txheem veneer thiab cov plywood substrate. Lub teb chaws tus qauv tau teev tseg tias qhov ntsuas no yuav tsum siab dua lossis sib npaug ntawm 50MPa, thiab tus naj npawb ntawm cov qauv ntsuas yuav tsum siab dua lossis sib npaug li 80 feem pua. Yog tias qhov ntsuas no tsis tsim nyog, nws txhais tau hais tias kev sib txuas zoo ntawm cov hniav veneer thiab lub hauv paus plywood tsis zoo, uas yuav ua rau cov hniav veneer txheej qhib thiab bulge thaum siv.

③Dipping thiab tev tawm qhia txog kev ua haujlwm gluing ntawm txhua txheej nplaum ntawm cov hniav veneer veneer plywood. Yog tias qhov ntsuas no tsis tsim nyog, nws txhais tau tias cov kua nplaum zoo ntawm lub rooj tsavxwm tsis zoo, uas yuav ua rau cov kua nplaum qhib thaum siv.

④ Formaldehyde tso tawm txwv. Qhov ntsuas no yog tus qauv tsim nyog hauv lub tebchaws uas tau siv hauv kuv lub tebchaws txij lub Ib Hlis 1, 2002, uas yog "daim ntawv pov thawj hnub yug" rau cov khoom muaj feem xyuam. Nws kuj yog "kev ua lag luam daim ntawv pov thawj" rau cov khoom lag luam. Txij li thaum Lub Xya Hli 1, 2002, cov khoom lag luam uas tsis ua raws li tus qauv no tsis raug tso cai nkag mus rau hauv kev lag luam ncig. Tshaj qhov txwv ntawm formaldehyde yuav cuam tshuam rau kev noj qab haus huv ntawm cov neeg siv khoom. Tus qauv qhia tias formaldehyde emission ntawm cov hniav veneer veneer plywood yuav tsum ncav cuag: E1 theem Tsawg dua los yog sib npaug rau 1.5mg / L, E2 qib Tsawg dua lossis sib npaug li 5.0mg / L.
