Izinga lekhwalithi elimayelana namabhodi okhuni eBanga A/B/C likaphayini we-FJ
Ayikho indinganiso yamazwe ngamazwe eyisibopho ehlanganisiwe yezinga lekhwalithi yamabhodi okhuni kaphayini-ohlangene (FJ) okwamanje, kodwa umkhakha wenze ukucaciswa okulinganayo okusekelwe ekubukekeni, ikhwalithi yokucubungula, nokusebenza.
Ngezansi izindinganiso zekhwalithi ezivamile zamabhodi ezinkuni zikaphayini we-FJ weBanga A, B, no-C, ahlanganisa izinqubo zomkhakha wasekhaya nezangaphandle kanye nezinkambiso zomhlaba wonke zomthengisi:
| Inkomba Yekhwalithi | Ibanga A | Ibanga B | Ibanga C |
|---|---|---|---|
| Amaphutha Obuso | Amafindo-angezinhlangothi ezimbili (okuhlanganisa amafindo amnyama, amafindo afile), awekho umumo wesihlahla, akukho ukushoda kwezinto. Kuphela 1 - 2 imigqa yamaminerali emincane - emincane engaminyene noma imigqa kawoyela evumelekile, futhi amaphakethe kawoyela kufanele abe phakathi kuka-10mm. Awekho amaphinifa ngokuyisisekelo, noma awekho amaphinikhodi angaphezu kuka-3 ohlangothini olulodwa. | Uhlangothi lwangaphambili alunawo amafindo, izinongo zezihlahla kanye nokushoda kwezinto ezibonakalayo; uhlangothi olungemuva lungaba namafindo nezinto eziwumgogodla wesihlahla. Umehluko omncane wombala kanye nebala eliluhlaza okwesibhakabhaka kwamukelekile, futhi amaphutha amancane angalungiswa. | Zombili izinhlangothi zingaba neziqu zesihlahla namafindo. Amafindo abukhoma phakathi kuka-10mm afana nombala webhodi avunyelwe. Amaphutha afana nebala eliluhlaza okwesibhakabhaka, amaphakethe kawoyela kanye nokuqhekeka okuncane kungaba khona kodwa kufanele kulungiswe kahle. |
| Umbala Nokwakheka | Umbala wezinhlangothi zombili ngokuyisisekelo uyavumelana, awukho umehluko wombala osobala, futhi ukuthungwa kufana futhi kucocekile. | Umbala wohlangothi olungaphambili ufana, kanti uhlangothi olungemuva lungaba nomehluko omncane wombala ngenxa yamafindo nezinhlamvu zesihlahla, futhi ukuthungwa sekukonke kucocekile. | Umehluko wombala nhlangothi zombili wamukelekile, futhi ukuthungwa okungalingani kuvunyelwe. Ukuguqulwa kombala kanye nemigqa yamaminerali kuvunyelwe, okungaphazamisi ukusetshenziswa okuyisisekelo. |
| Okuqukethwe Umswakama | Ilawulwa ngokuqinile ngaphansi kuka-12%, ngokuvamile igcinwa phakathi kuka-8% - 12%, iqinisekisa ukuthi ibhodi akulula ukusonteka noma ukuqhekeka phakathi nokusetshenziswa. | Ngokufanayo neBanga A, okuqukethwe komswakama akufanele kudlule u-12%, ohlangabezana nezidingo eziyisisekelo zokomisa zamaphaneli ezinkuni. | Ngokuhambisana neBanga A no-B, umswakama awukho ngaphezu kuka-12% ukugwema izinkinga ezifana nesikhunta esibangelwa umswakama owedlulele. |
| Icubungula Ikhwalithi | Zombili izinhlangothi zifakwe isihlabathi ngokushelela ngaphandle kwamagagasi esihlabathi. Ugqinsi luhlangabezana nezidingo ezishiwo, futhi iphutha elincane kuphela eliphozithivu nelibi phakathi kwebanga elivumelekile elivunyelwe. Amalunga eminwe kanye nemithungo kuqinile, akukho kukhishwa kwe-degumming noma ukuqhekeka. | Uhlangothi lwangaphambili lufakwe isihlabathi ngokushelela, futhi ukujiya kuhlangabezana nezinga. Amajoyinti eminwe nemithungo awanayo i-degumming noma ukuqhekeka, futhi asikho isidingo esiqinile sokuthunga isihlabathi ngemuva. | Ugqinsi luhlangabezana nezinga eliyisisekelo. I-Sanding ingase ibe nokungalingani okuncane kodwa akuthinti ukufakwa nokusetshenziswa. Amalunga eminwe kanye nemithungo ayinayo i-degumming kanye nokuqhekeka; izikhala ezincane ezingathinti ukuzinza kwesakhiwo ziyamukeleka. |
| Izimo Ezisebenzayo | Ukukhiqizwa kwefenisha ephezulu - ephezulu, izindawo zokuhlobisa zangaphakathi (njengamaphaneli odonga, amaphaneli eminyango yewadilobhu) nezinye izikhathi ezinezidingo eziphezulu zokubukeka nekhwalithi. | Ukukhiqizwa kwefenisha evamile (njengangemuva kwamakhabhinethi, ukuhlukaniswa kwangaphakathi), izingxenye ezisizayo zokuhlobisa nezinye izindawo lapho ukubukeka kohlangothi lwangemuva kungabonakali khona. | Izinto ezisizayo zokwakha, izinto zokupakisha, amapuleti angaphansi enefenisha - ephansi kanye nezinye izimo ezigxile kuphela emsebenzini oyisisekelo wesakhiwo futhi ezingenazo izidingo zokubukeka. |
Ngaphezu kwalokho, amanye amanothi angeziwe adinga ukugcizelelwa:
Uma abanye abakhiqizi bemaka amamaki ahlanganisiwe afana ne-AA, AB, ne-CC, babhekisela ekuhlanganisweni kwezinhlangothi ezimbili zebhodi.
Ngokwesibonelo,I-AA isho ukuthi izinhlangothi zombili ziyiBanga A, futhiU-AB usho ukuthi uhlangothi olungaphambili luyiBanga A kanti uhlangothi olungemuva yiBanga B.
Kumabhodi okhuni e-pine FJ asetshenziswa ezimweni ezikhethekile (ezifana nezingxenye ezithwele - zomthwalo), ngaphezu kokubukeka okungenhla namazinga okucubungula, izinkomba zokusebenza kwesakhiwo nazo zidinga ukuhlangatshezwana nazo. Amazinga afanelekile angabhekisa emithethweni yezikhungo ezifana ne-Western Wood Products Association (WWPA).
Emikhiqizweni ethambekele ekuthekeni -, uma ihlinzekwa ezimakethe zase-Europe nezaseMelika, ingase idinge ukulungiswa ngendlela efanele ngokuya ngezinkambiso zesifunda ezifana ne-European standard SS - EN 1611 - 1, kodwa le - imibandela yokugreda eshiwo ngenhla iseyisisekelo esiyinhloko senkomba.
Ngezansi kunezithombe zezinkinga ezijwayelekile zekhwalithi.
