He aha ka WBP plywood?

WBP plywoodhe plywood veneer kiʻekiʻe i hana ʻia me ke kāpili wai. He ʻokoʻa ia mai ka plywood ma ke ʻano o nā koi hoʻomaʻemaʻe kumu.
Ma ka ʻoihana plywood, kū ka huaʻōlelo WBP no Weather and Boil Proof ma mua o ka Water Boil Proof.
Ua maʻalahi ka paila wai. Hiki i nā papa plywood kumu kūʻai maʻamau ke hele maʻalahi i 4 mau hola o ka paila wai a i ʻole 24 mau hola inā paʻi maikaʻi ka papa. ʻOi aku ka paʻakikī o ka pale ʻana i ka wā no ka mea e pono ai ka plywood e pulu a maloʻo i nā manawa āpau e hoʻohālikelike ai i ka ua.
ʻO ka hiʻohiʻona koʻikoʻi o ka WBP plywood ka pale ʻana i ka wā. Paʻa maikaʻi ka WBP plywood i ka lā a me ka ua.
WBP plywood i hana ʻia me ka phenolic/melamine glue
Ua hana 'ia ka Plywood me 'ekolu a 'oi a'e ka pepa lahilahi o ka lā'au (i kapa 'ia nā veneers) i ho'opa'a 'ia, me ka waiho 'ana o kēlā me kēia papa ma nā kihi 'ākau i ka palaoa o ka mea a'e. 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 paʻi ʻana o 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.
