Amafekthri amaningi akhetha ukusebenzisa i-sycamore pine preservative wood njengempahla eluhlaza yendlu ye-cubby, kodwa abasazi isizathu.Okulandelayo, ngizochaza ngezici ezintathu.
Izici ze-sycamore pine:
I-Pinus sylvestris (Pinus sylvestris var. Mongolica Litv.) isihlahla esihlala siluhlaza, esingamamitha angu-15-25 ukuphakama, kufika kumamitha angu-30 ukuphakama, esinomqhele ovali noma oyikholi.Isiqu siqondile, amagxolo angaphansi kwamamitha angu-3-4 anombala omnyama-nsundu, anama-scaly futhi anama-lobed ajulile, amaqabunga ayizinaliti ezi-2 ku-bundle, eziqinile, ngokuvamile ezisontekile kancane, futhi i-apex ikhomba.I-Monoecious, izigaxa zesilisa ziyi-oval, ziphuzi, zihlangene engxenyeni engezansi yamagatsha alo nyaka;Izigaxa zesifazane ziyindilinga noma ziyi-oval, onsundu ngokunsomi.Izigaxa ziyi-ovate.Isikali sesihlangu simise okwe-rhombus, esinama-longitudinal and transverse ridges, kanti i-squamous umbilicus iyi-tumor-like protrusion.Imbewu incane, inombala ophuzi, onsundu, nonsundu ngokumnyama, inamaphiko angama-membranous.Ikhiqizwa ezintabeni ezingamamitha angama-400-900 ngaphezu kwezinga lolwandle ezintabeni zaseDaxinganling eHeilongjiang, eChina kanye nezindunduma zesihlabathi entshonalanga naseningizimu yeHailar.Ingasetshenziswa njengensimu yokuhlobisa kanye nezinhlobo zemithi eluhlaza.Izihlahla zikhula ngokushesha, zinempahla enhle nokuvumelana nezimo eziqinile, futhi zingasetshenziswa njengezinhlobo zezihlahla zokugawulwa kwamahlathi ezintabeni zaseDaxinganling eNyakatho-mpumalanga yeChina nezindunduma zesihlabathi entshonalanga.
I-Pinus sylvestris iwuhlobo lwesihlahla esihle kakhulu sokhuni olukhula ngokushesha, ukutshala okuluhlaza okuvikelayo, nokongiwa kwenhlabathi namanzi eNyakatho-mpumalanga yeChina.Izinto ezibonakalayo zinamandla futhi ukuthungwa kuqondile, okungasetshenziselwa ukwakha, ifenisha nezinye izinto.Isiqu singasikwa ukuze kwenziwe i-resin, amapheya kaphayini kanye ne-turpentine kungakhishwa, futhi amagxolo angakhishwa.
I-heartwood insundu ngokubomvu ngokukhanyayo, i-sapwood inombala ophuzi ngokukhanyayo, impahla icolekile, okusanhlamvu kuqondile, futhi kunenhlaka.Ingasetshenziselwa ukwakhiwa, izindawo zokulala, izigxobo, imikhumbi, izinto zikagesi, ifenisha kanye nezinto zokusetshenziswa zezimboni zokhuni.Isiqu singasikwa ukuze kwenziwe i-resin, i-rosin ne-turpentine ingakhishwa, futhi amagxolo angakhishwa ku-tannin extract.Ingasetshenziswa njengensimu yokuhlobisa kanye nezinhlobo zemithi eluhlaza.Izihlahla zikhula ngokushesha, zinempahla enhle nokuvumelana nezimo eziqinile, futhi zingasetshenziswa njengezinhlobo zezihlahla zokugawulwa kwamahlathi ezintabeni zaseDaxinganling eNyakatho-mpumalanga yeChina nezindunduma zesihlabathi entshonalanga.[1]
Ukuminyana emoyeni okomile 422kg/m3;ubulukhuni bezinkuni kanye nokuminyana kulinganiselwe, inkomba yempahla ebonakalayo iphakathi, ukubamba amandla kulinganiselwe;ukuthungwa kuhle futhi kuqondile, okusanhlamvu kwezinkuni kucacile, i-deformation coefficient incane;ukomisa, ukucutshungulwa kwemishini, ukusebenza kokwelashwa kwe-anti-corrosion kuhle;upende nokusebenza kokubopha kumaphakathi .Kulula ukudweba kanye nebala ngemva kokulondolozwa.Iwumkhiqizo oyinhloko wokhuni lwaseShayina olulwa nokugqwala, futhi ukucaciswa kwezinto ezinde kakhulu kuvamise ukuba ngamamitha ayi-6.
Ukwakheka kwesihlahla kanye nesiqu kuhle, futhi kungasetshenziswa njengezihlahla zokuhlobisa engadini neziluhlaza.Ngenxa yokumelana namakhaza, ukumelana nesomiso, ukumelana nendlala kanye nokumelana nomoya, ingasetshenziswa njengezinhlobo zezihlahla eziyinhloko zamahlathi okukhosela kanye nokugawulwa kwamahlathi okulungisa isihlabathi Ezifundeni Ezintathu EziseNyakatho.Ngemva kokugawulwa kwamahlathi endaweni enesihlabathi esindayo, ngokukhula kwezihlahla, akukhona nje kuphela ukuguguleka komoya okuncishisiwe, kodwa udoti wanda, futhi unomphumela wokuvimbela umoya nesihlabathi nokuguqula imvelo.
Izici ze-preservative wood:
Ukhuni olulondolozayo lwenziwa ngokungeza ngokwenziwa izivimbelakuvunda zamakhemikhali okhunini oluvamile ukuze lukwazi ukunqanda ukugqwala, umswakama-umswakama, ukuvimbela ukhunta, ukuvikela izinambuzane, ukukhunta nokungangeni kwamanzi.Kunezinto ezimbili eziyinhloko zokhuni olujwayelekile lokulondolozwa kwemvelo e-China: uphayini wesicamore waseRussia kanye nophayini obomvu waseNordic.Ingathintana ngqo nenhlabathi nendawo eswakeme, futhi ivame ukusetshenziswa ezitezi ezingaphandle, amaphrojekthi, indawo, izitendi zezimbali zokhuni ezilwa nokugqwala, njll., ukuze abantu baphumule futhi bajabulele ubuhle bemvelo.Kuyimpahla efanelekile yaphansi yangaphandle, indawo yasengadini, ukujika kokhuni, izindawo zokuzijabulisa, amapulangwe okhuni, njll.
Ukuhlanganisa izinto zokusetshenziswa zekhwalithi ephezulu nalokhu kwelashwa okunqanda ukugqwala kungaqinisekisa ikhwalithi yomkhiqizo ngangokunokwenzeka.
