5 mau mea pono e ʻike e pili ana i ke kiʻiʻoniʻoni i alo i ka Plywood

He aha ka plywood?

Hiki ke hoʻokaʻawale ʻia ka Plywood i nā lāʻau palupalu (masson pine, larch, red pine, etc) a me ka lāʻau paʻa (bass wood, birch, ash, etc.).

Mai ka hiʻohiʻona o ka pale wai, hiki ke hoʻokaʻawale ʻia ka plywood i ʻehā mau ʻāpana:

Papa I - Plywood kū'ē i ka wā a me ka paila wai kū'ē i ka wai (WBP), me ka hoʻohana ʻana i ka lāʻau phenolic resin.He kūpono no nā wahi o waho e like me ka mokulele, nā moku, nā kaʻa, ka hoʻopili ʻana, ka formwork concrete, hydraulic engineering, a me nā wahi ʻē aʻe me ke kūpaʻa wai maikaʻi a me ke kū ʻana i ke aniau.

Class II moisture resistant plywood (MR), hiki ke hoʻokomo i ka wai anuanu no ka wā pōkole, kūpono no ka hoʻohana ʻana i loko ma lalo o nā kūlana maʻamau.Hana ʻia ma o ka hoʻopaʻa ʻana me ka resin haʻahaʻa haʻahaʻa urea formaldehyde resin a i ʻole nā ​​mea hoʻopili ʻē aʻe me nā waiwai like.Hoʻohana ʻia no nā lako hale, ʻeke, a me ka hana maʻamau no ke kūkulu hale.

ʻO ka papa III wai kūpaʻa plywood (WR), hiki ke hoʻonā ʻia i ka wai anuanu, hiki ke kū i kahi manawa pōkole o ka wai wela, a he mau mea antibacterial, akā ʻaʻole kū i ka paila.Hana ʻia ia me ka resin urea formaldehyde a i ʻole nā ​​​​mea hoʻopili ʻē aʻe me nā waiwai like.Hoʻohana ʻia no ka hoʻonaninani kūloko a me ka hoʻopili ʻana o nā kaʻa, nā moku, nā lako, a me nā hale.

Papa IV non moisture resistant plywood (INT), hoʻohana ʻia i loko o ka hale ma lalo o nā kūlana maʻamau, loaʻa kekahi ikaika pili.Hana ʻia ma ka hoʻopaʻa ʻana me ke kolu pīni a i ʻole nā ​​mea hoʻopili ʻē aʻe me nā waiwai like.Hoʻohana nui ʻia no ka ʻeke a me nā kumu maʻamau.Pono e hana ʻia ka pahu kī i ka plywood kelu pī

ʻO ka plywood i hoʻohana ʻia no ke kiʻi ʻoniʻoni ʻoniʻoni i alo i ka plywood no ka papa I ka plywood me ke kiʻekiʻe o ka wā a me ke kūpaʻa wai, a ʻo ka mea hoʻopili ʻo Phenolic resin adhesive i hana nui ʻia mai ka poplar, birch, pine, eucalyptus etc.

1. ʻO ke kiʻiʻoniʻoni i alo i ka hoʻolālā plywood moana a me nā kikoʻī

(1)Hoʻolālā

ʻO ka plywood lāʻau i hoʻohana ʻia no ka formwork ka mea maʻamau i haku ʻia me nā papa ʻokoʻa e like me 5, 7, 9, a me 11, i hoʻopaʻa ʻia a hoʻōla ʻia e ke kaomi wela.

ʻAno.ʻO nā ʻaoʻao kikoo o nā papa pili e kū pono ana kekahi i kekahi, a ʻo ka mea maʻamau, ʻo ka ʻaoʻao ʻano o ka papa ʻili o waho e like me ka ʻaoʻao lōʻihi o ka ʻili lāʻau.No laila, he ikaika ka ʻaoʻao lōʻihi o ka lāʻau paʻa holoʻokoʻa, a ʻo ka ʻaoʻao pōkole he nāwaliwali.Pono e nānā i ka wā e hoʻohana ai.

(2) Nā kikoʻī

Nā kikoʻī a me nā ana o ke kiʻiʻoniʻoni i alo i ka plywood no ka formwork

2. Kiʻiʻoniʻoni ke alo i ka lāʻau plywood bka hana ʻana a me ka hiki ke hāpai

(1) Hana hoʻopaʻa

ʻO ka lāʻau paʻa no ka plywood i hoʻohana ʻia i ke kiʻiʻoniʻoni i alo i ka plywood moana ka nui o ka resin phenolic.ʻO kēia ʻano adhesive he ikaika hoʻopaʻa kiʻekiʻe a me ke kūpaʻa wai, ʻO ka wela maikaʻi loa a me ka pale ʻana i ka corrosion, me ke kūpaʻa wai hoʻolapalapa a me ka lōʻihi.

Nā Waiwai Hōʻike Paʻa Paʻa no ke Kiʻiʻoniʻoni i alo i ka Plywood Marine

I ke kūʻai ʻana i ka lāʻau pāpaʻi no ka hana paʻa paʻa, pono ʻoe e nānā mua inā pili ia i ka Plywood Papa I,

E nānā inā ua hoʻohana ka pūʻulu o ka plywood i ka phenolic resin adhesive a i ʻole nā ​​mea hoʻopili ʻē aʻe me nā waiwai like.Inā hoʻāʻo ʻia ke kaupalena ʻia nā kūlana a ʻaʻole hiki ke hoʻokō ʻia ka hoʻāʻo ikaika hoʻopaʻa ʻana, hiki ke ʻike koke ʻia kahi ʻāpana liʻiliʻi e ka wai paila.

E hoʻohana i kahi ʻāpana liʻiliʻi o 20mm square sawn mai ka plywood a hoʻolapalapa ʻia i ka wai paila no 2 mau hola.ʻO ka hoʻohana ʻana i ka resin phenolic e like me ka ʻāpana hoʻāʻo ʻaʻole e ʻili ma hope o ka kuke ʻana, aʻo ka ʻāpana hoʻāʻo e hoʻohana ana i ka resin formaldehyde pulse no ka mea e ʻili ka mea hoʻopili ma hope o ka kuke ʻana.

（2) Hiki ke amo

ʻO ka hiki ke amo o ka lāʻau plywood e pili ana i kona mānoanoa, ka ikaika kuʻi kūlou, a me ka modulus elastic.

Nā waiwai maʻamau o ka ikaika kuʻi kuʻi a me ka modulus elastic o ka plywood pani (N/mm2)

Hiki ke hoʻokaʻawale ʻia ke kūkulu ʻana i ka plywood pani pani cpncrete i ka plywood pani maʻamau a me ke kiʻiʻoniʻoni i alo i ka plywood.

Hoʻopili ʻia ka ʻili lāʻau pani pani ʻia me ka resin phenolic me ka waterproofing ikaika. I ka ninini ʻana i nā ʻāpana ʻāpana me ka hoʻohana ʻana i ka lāʻau paʻa paʻa paʻa e like me nā alahaka arch, nā kaola, a me nā kolamu, pono e hoʻokō ʻia ka ʻoʻoleʻa maʻamau a me nā helu helu, a laila pono e hoʻopili ʻia ke kāhiko hina i ka. ʻilikai.Hoʻohana nui ʻia i nā hale kīwila a me nā hale ʻoihana maʻamau.

Hoʻokumu ʻia ke kiʻiʻoniʻoni i mua o ka plywood ma ka uhi ʻana i kahi ʻāpana o ka pepa laminnation ma kahi papa hana maikaʻi. ikaika anti fouling hiki.

No ke ahakiʻiʻoniʻoni maka plywoodpipiʻi loa ke hoʻohālikelike ʻia me nā mea maʻamaupaʻa lāʻau lāʻaupapa hana?

1. ʻO ka pepa keleawe i lawe ʻia mai i hoʻopaʻa ʻia ma luna o ka plywood he mau hiʻohiʻona o ka maʻalahi kiʻekiʻe, ka palahalaha maikaʻi, a me ka maʻalahi o ka demolding.Ma hope o ka hoʻohiolo ʻana, maʻemaʻe ka ʻili o ka ʻili, e pale ana i ka pena kiʻi kiʻekiʻe, e hōʻemi ana i nā kumukūʻai, a me ka pōkole o ka manawa hana.Hōʻike ʻia ia e ke kaumaha māmā, nā ʻoki paʻa, ka hana hana maikaʻi, a me ka wikiwiki o ke kūkulu ʻana.

2. ʻO ke kiʻiʻoniʻoni i alo i ka plywood he mea hoʻohuihui kiʻekiʻe a me ke kaomi kiʻekiʻe, ʻo ia ka paʻa, kiʻekiʻe i ka ikaika, a he paʻakikī maikaʻi.ʻOi aku ka ikaika o ka piʻo ʻana ma mua o ʻelua o ka lāʻau.

3.) Ka wai ikaika.I ka wā o ka hana ʻana, hoʻohana ʻia kahi papa o ka resin phenolic no hoʻokahi papa o ka hoʻoheheʻe ʻana i ka wela me ka ʻole o ka hoʻolapalapa ʻana i ke kāpili no 5 mau hola, e paʻakikī ai ke hoʻololi i ka panel i ka wā o ka mālama ʻana.

4.) ʻOi aku ka liʻiliʻi o ka conductivity thermal ma mua o ka hoʻoheheʻe ʻana i ke kila, kahi mea e pono ai no nā mahana kiʻekiʻe i ke kauwela a me ke kūkulu hoʻoilo.

5. ʻOi aku ka kiʻekiʻe o ka nui o ka huli ʻana ma mua o ka lāʻau lapaʻau pani maʻamau, a hiki i ka nui o ka huli ʻana ke hiki i 12-18 mau manawa.

6.) Ke kū'ē i ka corrosion: ʻaʻole ia e hoʻohaumia i ka ʻili kaʻa.

7.) Māmā: Hoʻohana maʻalahi no ka hale kiʻekiʻe a me ke kūkulu alahaka.

8.) ʻO ka hana hana maikaʻi: ʻOi aku ka maikaʻi o ka hana ʻana o nā kui, nā ʻili, a me ka ʻeli ʻana ma mua o ka lāʻau ʻohe a me nā pā kila liʻiliʻi.Hiki ke hana ʻia i nā ʻano like ʻole o nā templates e like me nā pono hana.

9.) Hōʻano nui: ʻO 2440 * 1220 a me 915 * 1830mm ka nui loa, e hōʻemi ana i ka helu o nā hui a hoʻomaikaʻi i ka pono o ke kākoʻo formwork.ʻAʻohe warping, ʻaʻohe deformation, ʻaʻohe māwae.

10.) Kiʻekiʻe haʻahaʻa-haawe hiki, oi aku ka maikaʻi aahu pale 'ana ma hope o ka ili, a hiki ke hoohana hou i na manawa he nui;

11.) Maikaʻi māmā, 18mm mānoanoa kiʻiʻoniʻoni alo i ka plywood, me ka wae kaumaha o 50kg oluolu e lawe , ahu a hoʻohana.

Pehea e hoʻoholo ai i ka maikaʻi o ke kiʻiʻoniʻoni i alo i ka plywood?

ʻO ka mea mua, e nānā i ke ʻano a me ke kala o ka template.ʻO ke ʻano o ka kiʻiʻoniʻoni i alo i ka plywood maʻamau, nani, a lokomaikaʻi.

ʻO ka mea ʻē aʻe, ʻo ke kiʻiʻoniʻoni i alo i ka plywood me ka maikaʻi maikaʻi ʻole he ʻano ʻano ʻino.Ke hālāwai ʻoe i kahi kiʻiʻoniʻoni i alo i ka plywood me nā waihoʻoluʻu ʻeleʻele a me nā ʻāpana pena mānoanoa, hiki paha i ka mea hana ke uhi i nā hemahema o ka ʻili.

ʻO ka lua, e hoʻohana i ke ʻano o ka hele ʻana e nānā inā lawa ka paʻakikī.Hiki iā mākou ke koho maʻamau i kahi kiʻiʻoniʻoni i alo i ka plywood moana.Hiki i nā kānaka ke kū i luna a hehi.Inā ʻike maopopo ʻia kahi kani pohā, hōʻike ia he maikaʻi ʻole ka maikaʻi.A laila, ʻokiʻoki i ke ʻano o kahi ʻāpana lāʻau a nānā i kona mau hemahema a me kona ʻano puha.Inā loaʻa nā hewa a i ʻole nā ​​wahi nui ʻole, e ʻike ka kiʻiʻoniʻoni i mua o ka plywood i ka bulging, pohā, a me nā mea ʻē aʻe.

ʻO ka hope, hiki iā mākou ke hoʻolapalapa i ka hale ʻili i ke ʻano o nā ʻāpana lāʻau i loko o ka wai e nānā ai inā kūpono kona ikaika paʻa.E kau i ka hāpana i loko o ka wai paila no ʻelua hola e hoʻāʻo ai i ka ikaika hoʻopaʻa ʻana o ke kiʻiʻoniʻoni i alo i ka plywood.ʻO kēia ka mea e hoʻohālikelike ai i ka haki ʻana o ke kumu hale ma hope o 2-3 mau manawa o ka hoʻohana ʻana.Inā loaʻa nā hōʻailona o ka māhā, hōʻike ia ʻaʻole ʻoi aku ka maikaʻi o kona ʻano a maikaʻi ʻole kona hopena wai.Hiki ke ʻōlelo ʻia ʻo ke kūkulu ʻana i nā kiʻiʻoniʻoni i alo i ka plywood ke kumu o kā mākou papahana kūkulu hale, a ʻo ka maikaʻi o ka kiʻiʻoniʻoni alo i ka plywood e pili pono ana i ka pono o kā mākou mau hana kūkulu.
