I. Ibu -Arụ Ọrụ Nkwado: Uru Eke nke Nkwụsi Ike Structural
Ibu -Ikike nke ogwe osisi siri ike nwere njikọ chiri anya na njupụta ihe onwunwe ha, nhazi eriri na ọdịnaya mmiri. Dịka ọmụmaatụ, ụdị osisi siri ike dị ka oak na teak, n'ihi mgbidi cell ha siri ike yana mgbanaka na-eto eto, nwere ike nweta ike mkpakọ nke 50-80 MPa (megapascals), karịa 30{10}50 MPa nke pine nkịtị, na-eme ka ha dabara maka ngwa dị elu{12}} na-ebu ibu dị ka ụlọ ala na steepụ. Nhazi eriri ogologo gbakwasara agbawa na-enye mbadamba osisi siri ike ka ukwuu na-ehulata nguzogide n'ogologo ha. Mgbe ihichachara (ọdịnaya mmiri na-achịkwa na 8%-12%), enwere ike idowe modul ngbanwe ha na 8-12 GPa (GigaPascals kwụsiri ike), na-eme ka nguzogide nrụrụ dị ogologo oge. Ọzọkwa, site na ijikọta mkpịsị aka ma ọ bụ usoro nkwado nke lamination, ike njikọ ntụgharị nke mbadamba osisi siri ike na-abawanye nke ọma, na-agbasawanye ikike ha maka iji rụọ ọrụ n'akụkụ kọlụm.
II. Iwu gburugburu ebe obibi: nha iru mmiri na njikwa okpomọkụ
Mpempe osisi siri ike bụ "ihe nchekwa ihu igwe." Ọdịdị ha nwere porous (porosity nke ihe dị ka 30%{3}}45% na ikuku{10}} njupụta akọrọ) na-enye mmịnye mmiri dị ịrịba ama na ihe na-emebi emebi: mgbe iru mmiri dị n'ime ụlọ na-ebili, oghere cell nke osisi na-amịkọrọ mmiri; Mgbe iru mmiri na-ebelata, mmiri na-eji nwayọọ nwayọọ na-ahapụ ya, si otú ahụ na-ebelata ngbanwe iru mmiri site na 10%-15%. Data nnwale na-egosi na n'okpuru ọnọdụ ọkọlọtọ nke ogo 20 na iru mmiri 65%, bọọdụ siri ike nke dị 1cm nwere ike ịhazi ọnụego mgbanwe mmiri nke ihe dịka 0.5L/m² kwa ụbọchị. Ọzọkwa, osisi dị ala thermal conductivity (0.15-0.35 W / (m·K)) na-eme ka ọ bụrụ ezigbo mkpuchi. Ejikọtara ya na ihe nchekwa okpomọkụ ya, ọ na-ebelata mgbanwe okpomọkụ mberede na oghere ime ụlọ, na-eme ka nkasi obi dị ndụ dịkwuo mma. Ọrụ a dị mkpa karịsịa na nhazi ụlọ na-agafe agafe.
III. Ihe ịchọ mma ịchọ mma: Eke Eke na Uru Tactile
Akụkụ osisi siri ike 'ọka eke, gradients agba, na mmetụta elu na-emepụta uru ịchọ mma pụrụ iche. Ụdị osisi dị iche iche na-egosipụta njiri mara microstructural pụrụ iche: dịka ọmụmaatụ, ọka wavy, chevron - n'ụdị ukpa, ọka cherry kwụ ọtọ nke ọma, na ọka na-egbuke egbuke, nke mepere emepe. Enwere ike ịkwalite ihe ndị a niile site na ọgwụgwọ elu dị ka ihicha na ịhịa aka n'ahụ. N'ihe gbasara ihe nhụsianya, micro{4}}roughness (Ra value) nke 0.1-0.3mm n'elu ogwe osisi siri ike na-enye nkwụsi ike dị nro, na-emezu ihe ergonomic chọrọ nke "kọntaktị enyi na enyi." Ọzọkwa, phytoncides nke osisi wepụtara na-enwe mmetụta dị nro na irighiri akwara. Ihe omume bioactivity a na-abawanye uru mmetụta uche nke ogwe osisi siri ike na oghere nlekọta ahụike na ebe obibi dị elu.
IV. Ọdịgidere: Mgbochi- ịka nká na nchekwa emelitere
Ịdị ogologo nke ogwe osisi siri ike na-adabere na nkwụsị nke ire ere nke ụdị osisi na ọgwụgwọ nchebe na-esote. Osisi siri ike nke ebe okpomọkụ dị ka merbau na African rosewood, n'ihi na ha dị elu nke extractives (dị ka tannins na lignin), nwere ogo nguzogide ire ere nke klaasị I (ike ire ere), nke nwere ike iguzogide ọgụ ogologo ihe karịrị afọ 20 na-enweghị nchebe. Maka osisi softwood (dị ka fir na poplar), ọgwụgwọ agụụ na nrụgide na-eji ihe nchekwa impregnated (ACQ, CA) nwere ike ịgbatị ndụ ọrụ ha ruo afọ 15-25. Ihe mkpuchi dị n'elu (dị ka UV-lacquers na-agwọ ọrịa na mmanụ osisi wax) abụghị naanị na-eme ka nkwụsi ike na-eyi (ọnụahịa abrasion na-erughị ma ọ bụ ha nhata 0.15g/100r) kamakwa na-egbochi mmebi lignin na-akpata UV, na-ejigide nkwụsi ike agba ruo afọ 8-10.
