I-Plywood Classification

I-plywood ihlukaniswe i-plywood evamile (i-plywood efanelekile ukusetshenziswa kabanzi) kanye ne-plywood ekhethekile (i-plywood efanelekile ukusetshenziswa okukhethekile).

Izidingo zekhwalithi ze-plywood zifaka ibanga lokubukeka, usayizi kanye nezakhiwo zomzimba nezomshini.

Ibanga lokubukeka, usayizi, izakhiwo zomzimba nezomshini zomkhiqizo zifaneleka ngokuhlolwa okuthathu, ngaphandle kwalokho kubhekwa njengokungafaneleki. I-plywood izoba nesitifiketi sekhwalithi yomkhiqizo somnyango wokuhlola ikhwalithi womkhiqizi lapho ephuma efekthri, esibonisa uhlobo, ukucaciswa, izinga, amandla okubopha kanye nokuqukethwe kwamanzi kweplywood.

Ubukhulu nobukhulu beplywood evamile buyi-2.7mm, 3.3mm, 4.5mm, 5.5mm, 6mm... Kusukela ku-6mm kuya phambili, khuphuka ngo-lmm. Ugqinsi luyi-plywood encane esuka ngaphansi kuka-4mm. I-plywood engu-3 mm, 3.5 mm kanye no-4 mm ubukhulu yizinto ezijwayelekile. I-plywood yobunye ukuqina izokwenziwa ngokuvumelana phakathi komphakeli nomphakeli.

Inqubo yokukhiqiza i-plywood

I-Plywood iyi-laminate enamapulangwe amathathu noma ngaphezulu eyenziwe ngogodo olusontelwe lwaba yi-veneer noma isikwele sokhuni esihlelwe sibe ngokhuni oluncane futhi sinanyathiselwe ngokunamathela. Ama-Odd-ply veneers ngokuvamile ahlanganiswe nemicu yama-veneers asondelene ahlelwe ngokuqondile komunye nomunye. Ngakho-ke, kunezingqimba ze-plywood ezintathu-in, ezinhlanu-in kanye neziyisikhombisa kweziyinqaba.

Ngokwesakhiwo, i-veneer yangaphandle ye-plywood ibizwa ngokuthi i-surface plate futhi i-veneer yangaphambili ibizwa ngokuthi iphaneli, okuyibhodi elilodwa elinekhwalithi engcono kakhulu esetshenzisiwe. Ishidi eliphambene libizwa ngokuthi i-backing sheet futhi lenziwe ngamashidi angawodwa ekhwalithi ephezulu elandelayo. Ipuleti elilodwa elingaphakathi libizwa ngokuthi i-core plate noma i-middle plate futhi lakhiwe ipuleti elilodwa elinekhwalithi ephezulu kakhulu.
