Ipulangwe lenziwe ngezingqimba ezintathu noma ngaphezulu zeveneer ewugqinsi eyimilimitha noma ibhodi elincanyana elinamathiselwe ngokucindezela okushisayo.Ezivamile ziyi-three-plywood, i-five-plywood, i-plywood eyisishiyagalolunye kanye ne-plywood eyishumi nambili (eyaziwa kakhulu ngokuthi i-plywood emithathu, ibhodi yamaphesenti amahlanu, ibhodi yamaphesenti ayisishiyagalolunye, kanye nebhodi lamaphesenti ayishumi nambili emakethe).
Lapho ukhetha i-plywood, naka amaphuzu alandelayo:
1. I-plywood inomehluko phakathi kwezinhlangothi zangaphambili nangemuva.Lapho ukhetha i-plywood, okusanhlamvu kokhuni kufanele kucace, indawo engaphambili kufanele ihlanzeke futhi ibushelelezi, ingabi namahhadlahhadla, futhi kufanele ibe isicaba futhi ingabi namanzi.
2. I-Plywood akufanele ibe neziphambeko ezinjengomonakalo, imihuzuko, imihuzuko, nezibazi.
3. Ayikho i-degumming phenomenon ku-plywood.
4. Enye i-plywood yenziwe ngokunamathisela ama-veneers amabili anezinhlobonhlobo ezahlukene ndawonye, ngakho-ke lapho ukhetha, qaphela amalunga e-plywood kufanele aqine futhi kungabikho ukungalingani.
5. Uma ukhetha i-splint, kufanele unake ekukhetheni i-splint engakhululeki i-glue.Uma umsindo uphukile lapho ungqongqoza ezingxenyeni ezihlukahlukene ze-plywood, kufakazela ukuthi ikhwalithi yinhle.Uma umsindo uvaliwe, kusho ukuthi i-plywood ine-glue evulekile.
6. Uma ukhetha amapaneli e-veneer, kufanele futhi kukhokhwe kumbala ofanayo, ukuthungwa okungaguquki, nokuhlanganiswa kombala wezinkuni nombala wepende yefenisha.
I-China National Standard for Plywood: Amabanga ePlywood
Ngokwe-“Plywood-Specification for classification of plywood of plywood for general use” (I-Plywood-Isicaciso sokuhlukaniswa ngokubukeka kwe-plywood ukuze isetshenziswe ngokujwayelekile), i-plywood evamile ihlukaniswe ngamamaki amane ngokuya ngobuthakathaka bezinto ezibonakalayo kanye nokukhubazeka kokucubungula okubonakalayo kuphaneli. : Ibanga elikhethekile, ibanga lokuqala Ikilasi 1, Ikilasi 2 kanye Nekilasi 3, phakathi kwalo Ikilasi 1, Ikilasi 2 kanye Nekilasi 3 amamaki ayinhloko eplywood evamile.
Ibanga ngalinye le-plywood evamile linqunywa ngokuyinhloko ngokuvumelana nokukhubazeka okuvunyelwe kuphaneli, futhi ukukhubazeka okuvumelekile kwephaneli yangemuva, i-veneer yangaphakathi kanye nokukhubazeka kokucubungula kwe-plywood kunqunyelwe.
