ʻO ka mālama ʻana i ka ʻili o ka papa waena Birch Plywood (BB/BB & BB/CP)
Ma ke kahua o ka hana hale a me ka hopena o loko, he hopena koʻikoʻi ka mālama ʻana o nā mea i ka helehelena a me ka hana o ka manaʻolana. Plywood Birch Papa Waena (BB/BB & BB/CP) ua lilo mālie i mea koho no nā mea e hoʻohua ai me nā mea hana ma muli o kāna mau waiwai maikaʻi loa.
ʻO kekahi o nā hiʻohiʻona kaulana loa o ka plywood birch ʻo ia kona ʻano maʻemaʻe a kaulana. Ma hope o ka hoʻomaʻemaʻe maikaʻi ʻana, maʻemaʻe a ʻaʻahu ka ʻili o ka BB/BB grade plywood, ʻaneʻane ʻaʻohe hemahema a ʻike ʻole paha. ʻAʻole kēia hoʻomaʻamaʻa kiʻekiʻe kiʻekiʻe e hoʻomaikaʻi wale i ka hiki o ka plywood e hoʻopaʻa me nā ʻāpana like ʻole a me nā mea hoʻopau, akā hoʻemi maikaʻi hoʻi i ka nui o ka uhi i ka hoʻohana ʻia. Hiki i ka ʻili maikaʻi ke hoʻomaikaʻi maikaʻi i ka hoʻopili ʻana a me ka like ʻole o ka uhi, a laila e hōʻoiaʻiʻo ai i ka maikaʻi loa o ka makemake hope.
Ma ke ʻano o ka hoʻopau ʻana, hōʻike ka papa waena o ka birch plywood i ka pena pena. ʻO kona ʻili maʻemaʻe e hiki ai iā ia ke ʻae i nā ʻano uhi like ʻole, me nā varnish, pena a me nā ʻili. Hiki i nā mea hiki ke koho i kahi varnish maʻemaʻe e mālama i ke ʻano uku o ka lāʻau a hōʻike i kona nani kūʻokoʻa, a i ʻole e hoʻopili i ka pena ʻālohilohi e hoʻokō ai i kahi hopena ʻike pilikino. ʻAʻohe mea i koho ʻia ke ʻano hoʻopau ʻana, hiki i ka birch plywood ke hāʻawi i nā hopena kūpono e hoʻokō i nā pono pono o nā mea kūʻai like ʻole, e hōʻike ana i kona maʻalahi a me ka hoʻololi ʻana i ka hopena.
ʻO ka mālama ʻana o ka lāʻau birch ʻaʻole wale no ka nani, akā no ka hāʻawi ʻana i ka pale hou. Hiki i nā papa lāʻau lapaʻau i ka mālama pono ʻia ke pale pono i ka ʻaʻahu o waho, nā ʻōpala a me ka lepo. ʻO ka hoʻohana ʻana i ka varnish a me nā mea pale pale ʻē aʻe hiki ke hoʻonui nui i ka pale wai a me ka pale ʻana i ka palaka, i hiki iā ia ke mālama i kona helehelena maikaʻi ma nā wahi pulu a lepo paha. Eia kekahi, hoʻopaʻa maikaʻi kēia mau uhi i nā kukui UV a pale i ka nalo ʻana o ka lāʻau ma muli o ka lā o ka lā, no laila e hoʻonui nui i ke ola lawelawe o ka meaʻai.
Hōʻike ʻia ka hopena lapaʻau o ka lāʻau birch medium-grade i kona hiki ke hoʻololi i nā loli kaiapuni. ʻO Birch ponoʻī he kūpaʻa maikaʻi a me ke kūpaʻa. ʻOiai i loko o kahi kaiapuni me nā loli nui o ka haʻahaʻa a me ka mahana, hiki i ka plywood i mālama ʻia ke mālama i kona ʻano a me kona ʻano. Hiki i kēia waiwai ke hana maikaʻi i ka plywood birch i nā kūlana aniau like ʻole, kūpono no nā ʻano like ʻole o loko a me waho, a hoʻokō i nā kūlana kiʻekiʻe o ka hoʻohana.
Nā waiwai kino o ka Papa Waena Birch Plywood (BB/BB & BB/CP)
Plywood birch papa waena (BB/BB & BB/CP) makemake nui ʻia i ka hana ʻana i nā lako, nā mea hoʻopono a me nā noi ʻē aʻe ma muli o kāna mau waiwai kino maikaʻi. ʻAʻole pili wale kēia mau waiwai i ke ola lawelawe a me ka hana o ka mea, akā pili pū kekahi i ka maikaʻi a me ke ʻano o ka makemake hope.
ʻO ka mānoanoa
ʻO ka nui o ka plywood birch ma waena o 600 a me 700 kilokani i kēlā me kēia mika cubic, e hāʻawi ana iā ia i kahi kaulike maikaʻi o ka ikaika a me ke kaumaha. Hāʻawi ke kiʻekiʻe kiʻekiʻe i ka birch plywood i ka ikaika compressive a me ke kulou ʻana, kūpono ia no nā lako a me nā ʻāpana hana e amo ana i nā ukana kaumaha. I ka manawa like, hoʻomaikaʻi ka māmā haʻahaʻa i ka ʻoluʻolu o ka lāʻau birch i ka wā o ka lawelawe ʻana a me ka hoʻonoho ʻana, e hōʻemi ana i ka paʻa ʻia o ka hana, a pēlā e hoʻomaikaʻi ai i ka hana pono.
Ka ikaika
ʻO ka ikaika o ka plywood birch kekahi o kāna mau waiwai kino koʻikoʻi. Ma muli o ka papa, ʻoi aku ka maikaʻi o nā māka BB/BB a me BB/CP o ka plywood ma ke kulou a me ka ikaika tensile. ʻO ka maʻamau, ʻo ka ikaika wili o birch plywood ma waena o 30 a 50 megapascals (MPa), ʻoiai hiki i kona ikaika tensile ke piʻi i 40 a 60 MPa. ʻO kēia ikaika kiʻekiʻe e hiki ai i ka lāʻau lāʻau birch ke pale pono i nā pilikia like ʻole a me nā hopena o ka hoʻohana ʻana i kēlā me kēia lā, e hōʻemi nui ana i ka hopena o ka pōʻino i hana ʻia e ka hoʻohana. pono ʻole.
Paʻa
ʻO ke kūpaʻa o ka lāʻau lāʻau birch medium-grade kekahi o nā kumu nui e hana maikaʻi ai ʻo ia i nā ʻano kaiapuni. Hōʻike ka mea i ka pehu haʻahaʻa a me ka emi ʻana, ʻo ia ka mea e loli liʻiliʻi ka nui o ka lāʻau birch ma lalo o nā kūlana o ka haʻahaʻa a me nā loli wela. ʻO kēia hiʻohiʻona e hiki ai i ka lāʻau birch ke mālama i kona ʻano a me kona ʻano i loko o nā wahi pulu a maloʻo paha, e pale ana i nā pilikia e like me ka warping, ka pohā a me ka deformation, e hōʻoia. ana i ka hana lōʻihi o ka hewa.
Ka lōʻihi
ʻO ka lōʻihi o ka lāʻau birch kekahi o nā kumu kaulana i ka hana hale a me nā noi hana. ʻO Birch ponoʻī he kūpaʻa maikaʻi i ka corrosion a me ke kūpaʻa ʻaʻahu. Hiki i ka plywood i hana ʻia ke pale pono i ka lole o kēlā me kēia lā a me ka mana o ke kaiapuni o waho i ka wā e hoʻohana ai. Eia kekahi, hiki i ke kaʻina hana lapaʻau o ka birch plywood ke hoʻonui i kona lōʻihi, i hiki ke mālama i ka hana maikaʻi ma lalo o nā kūlana like ʻole.
Nā kahua noi
Hoʻohana nui ʻia ka ʻau birch medium-grade i ka hana ʻana i nā lako, nā mea hoʻopono o loko, nā hale kūkulu hale a me nā māla ʻē aʻe e pili ana. ʻO kāna mau waiwai kino maikaʻi e lilo ia i mea koho maikaʻi loa no nā lako kiʻekiʻe, nā keʻena, nā mea lawelawe a me nā mea hoʻonani pā. Me ka piʻi nui ʻana o ka ʻatikala no nā mea pili i ke kaiapuni a me nā mea hoʻomau, ua lilo ka birch plywood i kekahi o nā mea koʻikoʻi i ka hana hou ʻana ma muli o kāna mau hiʻohiʻona hou a me ka hana hana maikaʻi. .
