Fa'atomuaga: Le Taua o le Fa'apalapala Fa'apipi'i i Faiga Fa'aonaponei
Plywood fausaga o se tasi o mea e sili ona tumau faʻainisinia laupapa o loʻo faʻaaogaina i le fausiaina ma fale gaosi oloa i le salafa o le lalolagi. O lona tulaga fa'alava -faiga fa'apipi'i, uiga malosi, ma le mautu o le fa'atinoga ua avea ai ma filifiliga fa'atuatuaina mo fa'avaa faufale, faiga fa'avae, fomu, ma fa'aoga uta-.
E le pei o laupapa teuteu, o le fausaga o plywood e faʻamatalaina muamua efaʻatinoga faʻainisinia ma le tumau, nai lo foliga vaaia. I aso nei, a'o fa'atupula'ia tulafono faufale ma fa'atumauina le fa'atumauina, o le malamalama i vaega fa'apolofesa o le fau laupapa e le'i sili atu ona taua.
1. Fa'amatalaina o La'au La'au Fa'atonu
O le plywood fausaga e fa'ainisinia e ala i le fa'apalapalaina o veneers fafie manifinifi se tele ma fa'apipi'i i lalo o le vevela ma le mamafa. Filifiliga fa'apipi'i ma fa'avasegaga fa'apapa e iloa ai le malosi fa'apipi'i totonu o le laulau, mautu, ma le tete'e atu i le susu po'o le atuatuvale.
O vaega autu o le fausaga e aofia ai:
Fa'ailoga lanu -numera esemo le fa'atinoga paleni (3-ply, 5-ply, 7-ply)
Fa'asa'o -fa'atonu saitomo le tele-tulaga malosi
Fa'apipi'i maualuga ma fa'amalolo leleimo le -tumau umi
2. Mea Autu ma o Latou Aafiaga
O le filifiliga o ituaiga fafie ma veneer grade e matua aʻafia ai meatotino plywood fausaga:
2.1 Ituaiga Laau Lalelei
O laʻau vaivai e pei o pine, spruce, fir, ma larch e masani ona faʻaaogaina ona o:
La'ititi maualalo
Fa'atonuga alava tutusa
Lelei fa'apipi'i meatotino
2.2 Ituaiga Laau Malosi
La'au fa'alavalava (fa'ata'ita'iga, birch, poplar) e maua ai le malosi fa'aopoopo ma le mautu, e masani ona fa'aoga i fa'ailoga fa'apitoa po'o le maualuga-vaega e mana'omia ai uta.
3. Faiga Fa'apipi'i: O le Ivi Ivi o Fa'atinoga Fa'atulagaina
O ituaiga faʻapipiʻi e matua aʻafia ai le teteʻeina o le vai, malosi faʻapipiʻi, ma le umi o le ola:
Phenol Formaldehyde (PF)- sili ona fetaui mo fa'aoga i fafo po'o le susu-fa'aalia
Melamine-Urea Formaldehyde (MUF)- paleni o tau ma le susu
Urea Formaldehyde (UF)- talafeagai mo tulaga mago totonu
O le filifilia o le togi fa'apipi'i sa'o e fetaui ma le fa'aalia o le si'osi'omaga e taua tele mo le fa'atinoga i le taimi.
4. Fa'avasegaga e ala ile Fa'aoga ma Tulaga Fa'ata'atia
Ua fa'avasegaina plywood fa'atulagaina e tusa ai ma le fa'aogaina ma le tausisia o tulaga fa'avaomalo:
4.1 Vaega Fa'afale totonu
Fa'aoga ile fa'a'ofuofu o le fola, fa'amau puipui, ma fa'alo mo si'osi'omaga mago i totonu.
4.2 Fa'avaa Fa'afale i fafo
Faia i mea fa'apipi'i -sūsū ma talafeagai mo faufale i fafo, faufale, po'o taualuga i lalo o tulaga fa'apitoa.
4.3 Vaega o Gataifale ma Vaega Faapitoa
Fuafuaina ma fa'amautu mana'oga fa'apipi'i mo va'a, uafu, po'o mea fa'apipi'i -sūsū.
Tulaga e pei oEN, APA (PS1/PS2), ma le AS/NZSfa'amatala fa'amoemoega fa'atinoga i maketi eseese.
5. Meatotino Fa'ainisinia Autu e Iloiloina
O fua fa'ainisinia taua e aofia ai:
Modulus o le malepe (MOR):tete'e i le toilalo o le punou
Modulus of Elasticity (MOE):malo i lalo o le avega
Malosi sele:interlayer malosi fa'apipi'i
Fa'asagaga o le Siu fa'ama'i:taua mo teuteuga
Onosa'i mafiafia:fua sa'o
E tatau i tagata gaosi oloa ona fa'amautinoa le pulea faifaipea o nei ta'iala.
6. Fa'aoga masani ole Fa'apalapala Fa'apalapala
O le plywood faʻavae e faʻaaogaina lautele i:
Faiga fola ma lalo fogafale
Fa'ato'aga o le taualuga ma fa'alava puipui
Sima ma fale le tumau
Fa'atauga fa'apisinisi, pusa, ma fata
Mea fa'apitoa i totonu o pisinisi
O lona agava'a e avea ai ma mea fa'apitoa i le tele o alamanuia.
7. Iloiloga Fa'alesiosiomaga ma Fa'aauau
O le laupapa faufale e fesoasoani i fuafuaga fau fale gafataulimaina ona o:
Fa'aoga lelei fafie
Malosi fa'atusa maualalo pe a fa'atusatusa i le sila po'o le sima
E mafai ona fa'aogaina le carbon sequestration pe a fa'aputuina fa'atatau
Tusipasi e pei oFSC ma PEFCfa'aalia faiga fa'atauva'a.
Fa'ai'uga
O lo'o tumau pea le fa'avaeina o plywood ma fa'avae o faiga fa'ainisinia fa'aonaponei. Faatasi ai ma le filifilia lelei o meafaitino, faiga faʻapipiʻi, ma le tausisia o tulaga faʻatinoga, e tuʻuina atu faʻatinoga faʻalagolago i siosiomaga faʻatulagaina.
A'o fa'aauau pea ona fa'amamafaina e tufuga ma inisinia le fa'atumauina ma le fa'atinoga, o le a tumau pea le taua ma le taua o le matafaioi a le plywood.
