Kodi kusiyanitsa khalidwe la plywood?

Nazi njira zosavuta kusankha ndikusiyanitsa mtundu wa plywood:
Choyamba, zolakwika zomwe siziloledwa mumtundu uliwonse wa plywood ndi guluu lotseguka (kulekanitsa pakati pa zigawo za plywood), kuphulika (pali chikopa cha khungu kutsogolo ndi kumbuyo chomwe sichimangiriridwa ku bolodi lalikulu, kotero kuti imaphulika. pang'ono).Zolakwika ziwirizi zidzakhudza mwachindunji kugwiritsa ntchito plywood.

1. Mulingo wa gulu
Choyamba, m'pofunika kusiyanitsa gulu gulu la plywood.
mapanelo a plywood a dziko langa amagawidwa m'magulu anayi, omwe ndi giredi yapadera, giredi yoyamba, sitandade yachiwiri ndi giredi lachitatu.Gulu loyamba la plywood limakhala lopanda chilema (zowonongeka zazing'ono za munthu zimaloledwa);gulu loyamba la plywood limaloledwa kukhala ndi zolakwika zazing'ono (monga zolumikizira za singano, zolumikizira zakufa, mabowo a nyongolotsi, ming'alu, ma depressants, indentations, etc.);mapanelo a plywood amtundu wachiwiri amaloledwa kupatulapo pang'ono Kuphatikiza pa zolakwika zazing'ono, palinso zolakwika zina zazing'ono (monga chigamba, chigamba, cholakwika cha m'mphepete mwa bolodi);mapanelo a plywood amtundu wachitatu amalola zolakwika zambiri.

Ngati ndi plywood yochokera kunja, mulingo wake ungatanthauze mulingo wa plywood wakudziko langa wakuyika ndikuyika.

2. Kusanja
a) Njira: <1> Yendani mozungulira pa bolodi ndi manja anu, ndipo mutha kumva kusalala kwa bolodi;

b) Chizindikiritso: Plywood yapamwamba kwambiri, chifukwa cha zipangizo zake zabwino ndi ntchito zabwino, pamwamba pa bolodi lidzakhala lathyathyathya kwambiri ndipo limakhala losalala pakukhudza.Plywood yotsika, chifukwa cha zida zake zosauka, kupangidwa movutikira, ndi kutukuka kwakukulu kwamkati ndi kupatukana kwapakati, imatha kuwona kusagwirizana kwa bolodi ikamayang'ana kuwala, ndipo imamveka ngati yopingasa komanso yopingasa.

3. Core board khalidwe
Plywood yapamwamba kwambiri, bolodi lapakati ndi lonse, labwino kwambiri, ndipo mizere pakati pa matabwa apakati ndi yolimba;pamene bolodi likugwedezeka, phokoso limakhala "labwino".
Plywood yotsika, bolodi loyambira limalumikizidwa ndi matabwa ang'onoang'ono osweka, pali mabowo ambiri a nyongolotsi ndi zolumikizira zakufa pa bolodi pachimake, bolodi loyambira lili ndi zisonyezo zazikulu, ndipo kuyika kwake kuli koopsa kuchokera pachimake;pamene bolodi likugwedezeka, phokoso limakhala "lopanda kanthu".

4. Mphamvu
Kwezani mbali imodzi ya plywood ndikugwedeza mwamphamvu kwa kangapo.Ngati bolodi likumva lolimba, limatanthauza kuti liri ndi khalidwe labwino lamkati ndi mphamvu zapamwamba;ngati gululo "likugwedezeka" ndipo pali phokoso la phokoso, zikutanthauza kuti bolodi ili ndi mphamvu zochepa.Plywood yabwino kapena matabwa omwe ali ndi vuto lalikulu mkati mwa plywood amatha kusweka chifukwa cha kugwedezeka kwamphamvu.

5. Makulidwe
Plywood yapamwamba kwambiri, kulolerana kwa makulidwe pakati pa gulu lonse la matabwa ndi kochepa, ndipo makulidwe a mbali zosiyanasiyana za plywood imodzi ndi yunifolomu.

Plywood yotsika, kulolerana kwa makulidwe pakati pa gulu lonse la matabwa ndi lalikulu, makulidwe a magawo osiyanasiyana a plywood imodzi ndi yosagwirizana, ndipo kusiyana kwa magawo osiyanasiyana ndikokulirapo kuposa 1mm (tsopano makina a mchenga ndi abwino, komanso makulidwe ake. kulolerana kumakhala kochepa).

6. Fungo ndi kuteteza chilengedwe
Ngati bolodi limatulutsa fungo lopweteka, zikutanthauza kuti chitetezo cha chilengedwe cha bolodi sichiri choyenera;plywood yokonda zachilengedwe imatulutsa fungo la nkhuni palokha, zomwe sizimakwiyitsa.Komabe, ngati mukufuna kudziwa ngati plywood ikukwaniritsa zofunikira zachitetezo cha chilengedwe, muyenera kufunsanso bungwe lapadera lopanga matabwa kuti lichite mayesowo.
