I-Oriented Strand Board (OSB) iwuhlobo lwebhodi lesakhiwo elenziwe ngamapulangwe ayisicaba amancane futhi amade asomisiwe, ahlolwa, asetshenziswa ngezinamatheliso nezithasiselo, futhi acindezelwe ngokushisa ngemva kokuvula isiqondiso. Inamandla amakhulu ngoba yenziwe ngezingqimba eziningi zamapulangwe okhuni. E-Japan naseYurophu nase-United States, i-OSB ibhekwa njengepuleti elikhula ngokushesha, elithembisa kakhulu nelivuthwe kwezobuchwepheshe.
Njengamanje, ukusetshenziswa kwe-OSB e-United States kubalele ingxenye yengqikithi yokusetshenziswa kwamaphaneli enziwe umuntu, futhi kancane kancane sekuthathe indawo ye-plywood, i-veneer namanye amaphaneli enziwe abantu emisebenzini eminingi.

Isakhiwo sengxenye yeBhodi ye-OSB

Kuwuhlobo lwepuleti lesakhiwo eliqondisayo elenziwe ngokhuni olunobubanzi obuncane, ukhuni oluncane kanye nomgogodla wokhuni, olucutshungulwe lube ngu-40-100 mm ubude, 5-20 mm ububanzi kanye nama-flakes angu-0.3-0.7 mm aminyene ngemishini ekhethekile, futhi acutshungulwe nge-deoiling, ukomisa, ukunamathisela, ukugandaya okuqondisayo, ukucindezela okushisayo nezinye izinqubo. Ama-flakes awo ongqimba lwangaphezulu ahlelwe ngobude, futhi ama-flakes ongqimba oluyisisekelo ahlelwa ngokuphambene. Leli lungiselelo le-crisscross lihlela kabusha ukwakheka kwezinkuni, liqeda ngokuphelele umthelela wengcindezi yangaphakathi yokhuni ekucubunguleni, futhi lenze kube lula kakhulu ukucutshungulwa kanye nobufakazi bomswakama.

Ngenxa yokuthi i-OSB inesakhiwo esiqondisayo, awekho amajoyinti, ukuqhekeka, ukuqhekeka, ukufana okuhle okuphelele, namandla aphezulu okubopha angaphakathi, kokubili isikhungo kanye nonqenqema lwe-OSB kunekhono lokubamba izinzipho eliphakeme amapuleti avamile angeke afane. Ngokuthembela eJalimane, umbuso wemboni yamakhemikhali, i-adhesive esetshenziswa ipuleti yaseYurophu ibilokhu igcina isikhundla esihamba phambili emhlabeni. Ukukhishwa kwe-formaldehyde komkhiqizo oqediwe kuvumelana nezinga eliphakeme kakhulu laseYurophu (i-European E1 standard), elingaqhathaniseka nokhuni lwemvelo.

Izinzuzo nezici ze-OSB Board

1. Inezici eziphezulu zomzimba nezemishini, isakhiwo esihlangene namandla aphezulu.
2. Inezici ezintathu zokumelana ne-deformation, ukumelana nokuxebuka kanye nokumelana ne-warpage.
3. I-Anti-corrosion, i-mothproof, ukumelana nokuguqulwa, kanye ne-flame retardant enamandla.
4. Ukusebenza okuphelele okungangeni manzi, kungavezwa unomphela endaweni yemvelo kanye nezimo ezimanzi.
5. Ukukhishwa kwe-formaldehyde kuphansi kakhulu, okuwumkhiqizo wangempela wokuvikela imvelo oluhlaza.
6. Ukubamba okuqinile kwezinzipho, ukubona kalula, ukuziphophotha, ukubhola, indawo, indiza, ifayela noma isihlabathi.
7. Ine-insulation yokushisa enhle kakhulu, umphumela wokuvala umsindo kanye nokusebenza kahle kopende.

Inhloso yokusebenza kwe-OSB
I-OSB inokuqina okuhle namandla okubamba ngezikulufu eziphezulu. Izinto zayo ezingavuthiwe ikakhulukazi ukhuni oluthambile, ukhuni oluqinile olunobubanzi obuncane, ukhuni olukhula ngokushesha olulula, njll., njenge-eucalyptus, i-fir, i-poplar thinning wood, njll., enemithombo eminingi eminingi futhi engenziwa yenziwe ngamaphaneli amakhulu (anjalo. njengoba 8 × 32 izinyawo noma 12 × 24 izinyawo). Inqubo yokukhiqiza iwukuba ukomisa, ukunamathisela, ukuqondisa kanye nokucindezela ukushisa ama-shavings anomumo othile wejometri (imvamisa 50 mm - 80 mm ubude, 5 mm - 20 mm ububanzi, kanye 0.45 mm - 0.6 mm ubukhulu). Ubunzima bezobuchwepheshe buphezulu, futhi ukutshalwa kwezimali kwemishini kukhulu uma kuqhathaniswa, ikakhulukazi okokusebenza kwamanye amazwe, ikakhulukazi amabhiliyoni ambalwa noma ngaphezulu. Njengamanje, ubuchwepheshe bokukhiqiza baseChina "OSB" namandla okukhiqiza amathuluzi asemuva kakhulu kwawaseNyakatho Melika naseYurophu. Njengamanje, i-"OSB" eyinhloko emakethe isancike kakhulu ekuthengisweni kwamanye amazwe.

Uma kuqhathaniswa ne-plywood, i-medium-density fiberboard kanye ne-blockboard, i-OSB ine-coefficient ephansi yomugqa wokwandisa, ukuzinza okuhle, impahla efanayo kanye namandla okubamba isikulufu esiphezulu; Ngenxa yokuthi izinhlayiyana zayo zihlelwe ngendlela ethile, amandla ayo okugoba ubude makhulu kakhulu kunawe-transverse, ngakho-ke ingasetshenziswa njengempahla yesakhiwo kanye nelungu elithwala umthwalo. Ngaphezu kwalokho, ingasaha, ifakwe isihlabathi, ihlelwe, ibhojwe, ibethelwe futhi ifakwe njengokhuni, futhi iyimpahla enhle yokwakha isakhiwo, ukuhlobisa kwangaphakathi kanye nokukhiqizwa kwefenisha. Okubi ukuthi ukuzinza kogqinsi kubi, ikakhulukazi ngenxa yokuthi ubukhulu bezinhlayiyana buhlukile, futhi isiqondiso kanye ne-engeli yezinhlayiya enqubweni yokugandaya ayikwazi ukuba ivundlile ngokuphelele futhi ifane, ezokwakha i-gradient ethile yokuminyana, ene- umthelela othile ekuzinzeni kogqinsi.

Inzuzo yokukhishwa kwe-formaldehyde ephansi yamukelwa imakethe njengephaneli elisekelwe ngokhuni elithembisa kakhulu esikhathini esizayo, futhi i-OSB inendawo ebanzi yokusetshenziswa nokuthuthukiswa. Imakethe ibheka inzuzo yokukhululwa kwamahhala kwe-formaldehyde, engasetshenziswa ikakhulukazi ku: phansi, izindonga nophahla, i-I-imishayo, amabhodi okuhlukanisa ahlukene, amabhokisi okupakisha, ama-pallets wezimpahla namabhokisi okugcina, amashalofu wempahla, ideskithophu yezimboni, i-hardwood floor. umgogodla, i-air baffle kanye ne-guardrail, amaphaneli odonga okuhlobisa, ukubunjwa kukakhonkolo wasegcekeni, ama-container floor, i-bowling alley, njll.

Ngemuva kokucubungula, izothatha indawo ye-blockboard, i-plywood, i-plywood, i-formwork yesakhiwo, ibhodi elingashi, ibhodi lokuhlobisa kanye ne-MDF. I-liner ephakathi kwesitezi esiqinile sokhuni kanye ne-keel, noma isisekelo sezinto ezenziwe ngokhuni oluhlanganisiwe. Ipuleti lesakhiwo lefenisha nezinto zasekhishini. Ibhodi likalayini, iphaneli yangaphakathi, ibhodi lokuvikela ukushisa, ibhodi elimunca umsindo, isilingi kanye nephaneli yodonga yokwakha. Ipuleti eligcinayo, i-formwork yomsele, i-base plate, njll. ukuze kwakhiwe. Ngemuva kokuthi indawo ye-OSB inamathiselwe ohlangothini olulodwa, ingasetshenziselwa ibhodi elingenalutho, ipuleti lesisekelo sekhabethe, ibhokisi, ukuhlukaniswa kwekhabhinethi, ibhodi eliphansi, ibhodi lombhede, njll. ekwenzeni ifenisha.
