WBP kahupapa. He aha te momo o te rauemi. Momo, momo, utu

Kahupapa - kiri i roto i te puka o paraharaha tapawha, e kua hanga tikanga te honohono maha o ngā paparanga o te rakau veneer. Kei te whānui whakamahia te reira i roto i te hanga, engineering, taonga ahumahi me te tahi atu mara. E mea pinepine kiritaki noa ui te uiraa: "? WBP kahupapa - he aha te mea te reira" Mō tenei hua, ona āhuatanga, ka kia kōrero painga i roto i tenei tuhinga.

Āhuatanga WBP kahupapa

Na, kahupapa WBP - he aha te auraa i te reira? F - kahupapa, SF - phenol formaldehyde kapia piripiri. Ko tēnei rauemi kākano hanga o birch, tawai pine veneer ranei. Kua nui haere te reira i ngā āhuatanga resistance wai. ngā kahupapa o toru, neke atu rānei ngā papa o te veneer Katahi formaldehyde kāpia. Kei te āhuatanga i ia e paparanga whero pouri ranei pouri piripiri parauri i waenganui i te mau papaa parau, e taea te kite i nga pito o te matatahi.

FSF kahupapa, āhuatanga hangarau e tukua tona mahi i roto i tetahi tikanga makariri, - he rauemi māori ki te ahua rerehua ataahua. Kei te whakamahia te reira mo te hanganga me te whakarakai waho. E kore e tūtohu ana ki te tono i te rauemi i roto i te whare, rite kei reira matū paitini.

Makuku-ātete kahupapa e taea te hanga o te softwood. E ai ki te hangarau, i roto i te papa o waho kia reira veneer pine. pea te paraharaha ā o te maro. Whakamahia tenei kahupapa i roto i te hanga. he ātete ki te pirau te reira, ki te harore. PSF kahupapa Birch āhuatanga e te kounga pai, kaha, kakahu resistance me te utu nui. E hanga o te rakau birch paparanga katoa i roto i tenei hua, ko reira 15-20% kaha me te taimaha atu softwood.

kaha kurut wai-ātete WBP kahupapa:

• Kurut 40 MPa;
• Flexural - 60 MPa;
• na roto i te piri atu o te apa piripiri - 1.5 MPa.

Scope

FSF kahupapa, ngā tohutohu e e tiketike nui ki te whakatika i tona whakamahi i roto i te mara o te engineering hiko, i roto i te ahumahi rererangi, i roto i te hanga, i roto i te pereoo, te ahumahi automotive. Whakamahia tenei rauemi i roto i te hanga o ngā hanganga anga, taiepa, hanganga formwork, tuanui. whakamahia whānuitia PSF 18 mm kahupapa mō te hanga taonga waho, papa pānuitanga waho, pōkai me oko.

painga o te kahupapa

WBP kahupapa (aha te mea tenei mea - te mea i roto i te tuhinga i runga i tuhituhia) He maha ngā painga.

1. ātete makuku nui ake. Makuku te condensate ranei e kore e pā tona mahi. Heoi, e kore e pupuhi reira, e kore e mahuti me tonu te āhuatanga o te kaha.
2. Ātete ki te kino aunoa. Nā ki tona hanganga e ātete ki piko deformation me te whaturama nga veneers. He kaha me te roa tēnei rauemi rakau.
3. Tapatahi, me te tere o te tāutanga. He ngāwari ki te tukatuka, ngāwari ki te whakamahi i te rauemi, e whai wāhi ana ki te tāutanga ngāwari, me te tere. Āpiti ko reira taea e te tikanga o te tīwiri, pokekore, whao. haere pai te reira ki ētahi atu rauemi waihanga tūturu ranei.
4. Ringa rehe e. Tika, tukua ātete wai ki te whakamahi i te reira i roto i ngā tono.
5. Whakatākupe i roto i te te whāwhā. Kahupapa PSF, ahakoa kua pai ake te reira kaha, taputapu tukatuka ngāwari. ohaoha reira ano pai ki te orooro, kōhao, tapahi.

whakarato ēnei tohu te rongonui o te kahupapa, tona tono i roto i te ahumahi, me te hanga.

Huakore o kahupapa WBP

• Tāoke. I roto i te hanga o te kahupapa whakamahia wāhanga carcinogenic e pā hauora tangata. e kore te mea e tika ana mō te whakamahi roto Whakamahi o tenei rauemi.
• Combustibility. He pūkākā te rauemi.

FS kahupapa kōeke

Kahupapa FS wehewehe rima māka: E (whiriwhiri), 1, 2, 3, 4. hāngai te rauemi wehenga i runga i kāwai kei i runga i te papa o waho o te mata:

• E - kounga tino o te pepa waho;
• Ahau (B) - he hua ki he mea kohakore kitea;
• II (BB) - ngaro o knots i roto i te whārangi kahupapa kia aroaro whakaaetia o ira pango;
• III - (SR) he taea hē taatiraa veneer fakahū;
• Grade IV (C) - whakaaetia te aroaro o knots;
• SS - te kōeke o raro i runga i te taha o te koaka he pūhui veneer kitea, me te tahi atu kohakore.

E ai ki te tohu o te maimoatanga mata PSF taea e:

• NS - e kore whenua;
• W ranei W 1 - ki te huri unilateral;
• W ranei W 2 - ki huri rua-taha.

Na roto i te rauemi tapanga me ngā momo tāpiri huru pūrārangi, e te tikanga te whānuitanga o te tukatuka whārangi. I tua atu, kia mohio ki te tautuhi i te piha haapiiraa o te formaldehyde paheke. Te whakaputa kahupapa tenei momo 4-40 mm o. Ngā āhuatanga o peita kahupapa WBP he: 1525h1525, 1220h2440, 1250h2500 mm.

Me pēhea te ki te wehewehe i te PSF ki ētahi atu momo o te kahupapa

Ki te kahore koe e mohio pehea rerekē i ētahi atu momo o te kahupapa WBP, he aha te mea tenei mea, he aha ona āhuatanga e, ui te kaiāwhina hoko ranei tautuhi koutou ake e ona āhuatanga waho. I nga pito o pungawerewere i waenganui i nga papa o te veneer koputaputa kitea o te kāpia tae pouri. FK kahupapa, i roto i te rerekē ki te FSF, kua he marama āputa kāpia kōwhai.

utu

Ki te hiahia koe i kahupapa WBP wai-ātete, kia rerekē pepa utu o te rahi kotahi, me te matotoru. Whakatau tuatahi ki te rauemi. tei te utu i runga i te ahua o te hua, me tona kaihanga. Ko te maha o hē reira i runga i te mata o te waho rauemi papa tautuhi tetahi atu o tona momo ranei. A, o te akoranga, te teitei te māka, te atu utu te hua. Mai E rua taha e waho kahupapa, whakaritea te kōeke e te tauanga rua, hei tauira 2/4. I tua atu, i ia kaihanga o kahupapa WBP whakatakoto ana ona utu mō ngā hua hangaia. Na reira, ko te utu he iti e pā ana ki te kounga o te hua.
