WBP plywood i hana ʻia me ka phenolic/melamine glue
Hana ʻia ka Plywood me ʻekolu a ʻoi aʻe paha ʻāpana lāʻau lahilahi (i kapa ʻia ʻo veneers) i hoʻopili ʻia, me kēlā me kēia papa e waiho ʻia ma nā kihi ʻākau i ka palaoa o ka mea aʻe.Hoʻokumu ʻia kēlā me kēia plywood me kahi helu ʻokoʻa o nā veneers.ʻOi aku ka ikaika o ka lāʻau ma mua o nā papa a ʻoi aku ka liʻiliʻi o ka hoʻopaʻa ʻana i ka lāʻau.
ʻO WBP plywood kekahi o nā ʻano lāʻau paʻa loa.Hiki ke hoʻopili i ka melamine a i ʻole ka resin phenolic.No ka noʻonoʻo ʻia ʻana o ka pae o waho a i ʻole ka pae moana, pono e hana ʻia ka lāʻau plywood me ke kāpili WBP.Pono e hana ʻia ka plywood WBP maikaʻi me ke kāpili phenolic.
ʻO WBP plywood i hana ʻia me ka melamine maʻamau ma mua o ka phenolic e paʻa i ka lamination no 4-8 mau hola i ka wai paila.Hiki i ke kāpili melamine kiʻekiʻe ke kū i ka wai paila no 10-20 mau hola.Hiki i ke kāpili phenolic premium ke kū i ka wai paila no 72 mau hola.Pono e hoʻomaopopo ʻia ʻo ka lōʻihi o ka manawa e hiki ai i ka plywood ke kū i ka wai paila me ka ʻole o ka delamination e pili pū ana i ka maikaʻi o ka veneer plywood.
Hoʻolālā ʻia ʻo WBP no ka hoʻohana ʻana i waho
ʻO ka hapa nui o nā kumu i kapa ʻia ʻo WBP ma ke ʻano he wai paila, akā ʻaʻole pololei kēia.Ua hoʻomohala maoli ʻo WBP i ka maʻamau ma UK a ua ʻōlelo ʻia ma ka British Standards Institution Standard 1203:1963, e hōʻike ana i nā papa ʻehā o nā glues plywood e pili ana i ko lākou lōʻihi.
ʻO WBP ka mea paʻa paʻa loa e loaʻa iā ʻoe.Ma ke kaʻina iho o ka lōʻihi, ʻo nā māka kepau ʻē aʻe he kūpaʻa kuke (BR);pale i ka wai (MR);a me loko (INT).ʻO ka Plywood WBP i kūkulu pono ʻia ʻo ia wale nō ka plywood i ʻōlelo ʻia no ka hoʻohana ʻana i waho, e like me ka Food and Agriculture Organization o United Nations.Hoʻolālā ʻia ʻo WBP plywood no ka hoʻohana ʻana i waho e like me ke kūkulu hale, nā hale a me nā uhi, nā hale, nā papahele pahu, nā mea hana paʻa a me nā mea hou aku.
He aha ka plywood wai?
ʻOiai ke hoʻohana nui nei ka poʻe i ka huaʻōlelo, ʻaʻohe plywood wai.ʻO ke ʻano o ka “waterproof” ʻo ia hoʻi he paʻa phenolic paʻa ka lāʻau ʻaʻole e pōʻino i nā kūlana pulu.ʻAʻole kēia e hana i ka plywood "waterproof" no ka mea e hele mau ana ka wai ma nā ʻaoʻao a me nā ʻili o nā papa.
