Ukhuni Solid: okuyinto ke?

Emasimini eSifundazweni ukwakhiwa kanye ekukhiqizeni ukuba esikhundleni ezivamile consumable tech amapulasitiki ukuza imiklamo ehlukahlukene. Basuke izimpawu izimfanelo okusezingeni eliphezulu lobuchwepheshe kanye ngokomzimba ukuthi ubavumele ukuba ngokuqiniseka esikhundleni, nokhuni, ngisho metal. Nokho, izinkuni impahla eluhlaza kunezinzuzo eziningi ngenxa eziphansi sokuthenga nokuhlanzeka kwemvelo. Indawo ezibuthakathaka amandla efanayo impahla kubhekwa. Ukuze uthuthukise le nkomba abakhiqizi eziwasebenzisayo zokuwugaya ekhethekile ukwandisa ukuqina, ukuminyana nokumelana jikelele ukuze umonakalo lokukhanda. Nokho, wokhuni oluqinile ekuqaleni lezi izakhiwo, ngokuvamile isidingo esikhethekile ukushisa ukwelashwa.

Izici oluqinile

Ngokuvamile izimfanelo rocks enjalo kulinganiswa ezindaweni ezintathu - kwabantu, ubulukhuni, Brinell ubulukhuni futhi ukunquma esiphambanweni. I kwabantu isilinganiso ugodo enjalo imayelana 1200-1400 kg / m ^3. Ngokuphathelene ubulukhuni HB, lesi silinganiso ongafinyelela 3.5 kgf / mm ^2, futhi rigidity kwesiphambano-cutting - 80 MPA. Nalapha futhi, lezi zibalo ejwayelekile izimo evamile izihlahla Russian nezinhlobo exotic ungase ube ukusebenza kakhulu aphakeme. Hlobo luni izinkuni abaqinile ezonini esipholile? Ngokuvamile bebodwa oki, beech, umlotha futhi hornbeam ezinye izinhlobo zawo. Kubalulekile ukukhumbula ukuthi lezi zihlahla futhi izimfanelo ezahlukene nemibi, kanye izinga omuhle ka ubulukhuni. Kuye kuthiwe ukuthi ukuze uthuthukise ukusebenza ugodo kungase ngaphansi ukucutshungulwa ezengeziwe. Ngezinye izikhathi, izici ezithile ngokomzimba leyo misebenzi echayeke nezinkuni kanzima. Futhi lapha kubonakala kuyinkinga engathi sína, njengoba amatshe amaningi ngenxa high density abakwazi ukuma ukugaya inqubo, impregnation futhi ikakhulukazi iphele. Ngokuvamile uqhekeke, chips, kanye nezinye izenzo ukusonteka isakhiwo.

Ekulinganisweni izingodo okuqinile

Ukwabela zinhlobo ezikhulayo ezonini athokomele, nemithi angavamile. Kukhona ngezigaba ku lezihlahla nezinhlobo coniferous. Nakuba iningi imishini yokusaha izingodo zisekhona lezihlahla, phakathi conifer zinhlobo futhi zenzeka nge high ukusebenza kwabantu kanye rigidity. Ngokuphathelene zezintaka zone athokomele, ukuthi bafake Maple, boxwood, hornbeam wathi briar. Nazi oluqinile ezivamile futhi coniferous. Miphi babe izinkomba ovelele ubulukhuni? Kulokhu, ukunakekelwa okufanele ikhokhwe larch, yew, umjunipha, Lawson. Kukhona hardwoods futhi phakathi evamile izihlahla zezithelo - apula esihlahleni ihlathi imele kulesi sigaba, oxalis, ipheya, mountain ash futhi abanye ziyadliwa. Njengoba zinhlobo ezingavamile, bona abonise amazinga aphakeme we ubulukhuni kanye kwabantu. Lapha, okunabileko iyona obomvu ne jusi izihlahla, i-rosewood zikagamthilini nokunye. D. Manje kubalulekile ukucabangela kulapho hardwoods kakhulu.

mahogany

ERussia, lokhu zohlobo ithandwa kakhulu, ngoba angathengwa emakethe evulekile. Kungumuthi ezishisayo libhekene ubulukhuni okusezingeni eliphezulu, kanye ukuthungwa yoqobo cut. Asanda ukhuni lithi wanqunywa kuyinto ezibomvu tint, kodwa ngokuhamba kwesikhathi ke esikhundleni amathoni mnyama, okwenza izinto ezihloniphekayo. Ngakho, umthengi uyakwazisa hhayi kuphela izici lobuchwepheshe kodwa futhi zokuhlobisa yalesi sihlahla. Kumele kuqashelwe ukuthi kusukela umbono esashiwo izimfanelo zokuhlobisa kuya oluqinile futhi lignum umlandvomphilo boxwood. Futhi la madwala kungukuthi kuphela esetshenziswa njengoba izinto zokuhlobisa, kodwa futhi kungaba isikhundla izinto zokuhlobisa imikhiqizo zokuhloba kanye namadivayisi lobuchwepheshe. Kodwa-mahogany ngaphandle ezahlukene futhi kalula machining. Kwabantu lokhu zohlobo akuyona okusezingeni eliphezulu ngakho kuqhathaniswa izinto eziningi okuqinile Lokudabuka ezishisayo, ngakho-ke lokhu impahla eluhlaza kakhulu ezifunwayo namafemu ifenisha.

Uma ezisindayo-duty plastic Ungashintshanisa yensimbi ngenxa ukuqina yayo, lokhu zohlobo uyakwazi hhayi kuphela kwezinye izindawo ukuthatha indawo amelana mechanical ukucindezeleka isici, kodwa ngesikhathi esifanayo, kusabela futhi ngakhula nezimfuneko ngokuya ukumelana kwemvelo. Ngaphansi nomqondo ironwood sifaka iqembu amatshe, okuyinto ngokuyinhloko kwanda emazweni ase-Asia nase-Australia. Ummeleli zakudala qembu Persian Parrot. Lolu hlobo kwasakazwa emahlathini relict, lapho abantu bendawo kusukela ezikhathini zasendulo yayivuma kuwo izibambo imimese izimbazo. Namuhla, 'nensimbi' oluqinile izihlahla ingaphansi Ukuvikelwa UNESCO. Lolu hlobo, ikakhulukazi ukubaluleka yobuhle, elibangela intshisekelo enkulu kuwo kusuka emakethe.

Merbau

Akukona enzima, kodwa inhlanganisela nezinye izici ukusebenza, singasho zohlobo esiwusizo kakhulu. Ngasekuqaleni lesi sihlahla ezisetshenziselwa ukwakha imikhumbi. Lokhu kungenxa yokuthi okuqukethwe amelana umswakama futhi, ngaphezu kwalokho, ingabe ngeke inqamuke. Ngakho-ke merbau zingagcinwa isikhathi eside, bese beshushisa ukufudumeza ukwelashwa kanye ezisetshenziselwa ukwakha. Njengoba sekuphawuliwe kakade, izihlahla okuqondene wokhuni oluqinile, efana beech noma hornbeam, cishe awukwazi ukubekezelela ukucutshungulwa ezengeziwe. Kodwa merbau steadfastly kwenza izindlela zesintu ithonya ukuze sithuthukise ukusebenza ngabanye.

izinkumbi

Idwala sekukaningi eRussia, okuyinto lwaziswa hhayi kuphela amandla, kodwa futhi ngoba ukuzinza izinqubo nolokubhujiswa begazi. Ngaphezu kwalokho, lolu hlobo ngomuthi kahle luze ngeke inqamuke phakathi operation okuqhubekayo. Ngokweyame izinyathelo zokuzivikela ukwelashwa futhi ukhuni bangaveziwe umonakalo ezincane lokukhanda. By the way, izici lobuchwepheshe lolu hlobo oludlula hardwoods ezifana oki, * umlotha.

Umkhiqizo lokhu ubulukhuni emthini omunye eliphakeme kunawo wonke emhlabeni. Engingakusho nje ukuthi izinto ngokufanele sibhekane ngokuphumelelayo imisebenzi yabo uma kusetshenziselwa njengoba amabombo, bushings kanye kubakaki. Lasemanzini ngokuvamile izinkuni zilwane isetshenziswa njengoba material for emphemeni. Kodwa imithi lignum vitae zenani nangenxa yezinye izizathu. Akakwazi kube ngaphansi kwethonya deforming izinqubo izici zangaphandle ezimbi. Kungaba nemiphumela kokubili chemical nomzimba, akudingeki zilimaze isakhiwo. Kukhona nezinye izindawo ukhuni oluqinile futhi amelana imithwalo kakhulu. Kodwa izinga eziyingqayizivele Lignum vitae luyinhlanganisela olinganiselayo mass esikhulu kanye kwabantu.

Ukusetshenziswa okhunini oluqinile

Iningi ezisetshenziselwa ukwakhiwa. Imithi ngandlela-thile ingasetshenziswa njengesisekelo izakhiwo noma njengoba umhlobiso. Sebenzisa uhlobo ahlukene ezindaweni isiqoqi sama-softwe nokwenza yomculo. Kulezi zingxenye ngabanye obusebenzayo Kwenziwa okubhekwe ukusetshenziswa eside - futhi kungase okudlekayo isikhathi, izingxenye kanye imiklamo okuhlala. Lona main, kodwa hhayi kuzo zonke izindawo, lapho siqashe ephezulu amandla ukhuni. Soft, rock kanzima, kanye nezinhlobo izinkuni nge kwabantu isilinganiso ingasetshenziswa ngezinhloso zokwelapha. Kulokhu, nobulukhuni akubalulekile kangako. Iqiniso lokuthi abaningi kwezinhlobo ezingavamile aqukethe eyingqayizivele izinga resin. Ukulungiselela compounds zokwelapha ukusetshenziswa zangaphakathi nezangaphandle, ngokukhethekile, ivumela amalunga omzimba alwa nezifo kwezitho zokuphefumula nokunye. D.

isiphetho

Abakhiqizi zokwakha ngokuphelele ujwayelene umthetho ukuthi ukwanda izici lobuchwepheshe kanye nokusebenza cishe ihilela ukunciphisa ezinye izimfanelo. Ngokwengxenye, lo mthetho kusebenza futhi okhunini oluqinile, okuyinto ezinye izici zohlobo ezithambile ulahlekelwe. Izinqubo biodegradability, ukusonteka ngokomzimba futhi ukuhlanekezela ukuthungwa - bokwenza eyinhloko softwood elisetshenziswa ukwakheka obude. Kodwa ngakolunye uhlangothi, ugodo has inzuzo ukuchayeka ukwelashwa okwengeziwe. Yiqiniso, kuzo zombili izigaba, kunokuningi okungakhulunywanga ngakho, kodwa ukuthungwa esithambile ukuminyana ongaphakeme namanje ithambekele kakhudlwana kumiswa izakhiwo ezintsha ngemishini.
