OSB inogadzirwa nematanda mahombe emapuranga echimiro chakatsanangurwa uye ukobvu mushure mekunamatidza uye nekuaisa munzira inotungamira, uye ipapo inopisa-yakadzvanywa kuti igadzire akawanda-layer dhizaini bhodhi, uye iyo yepamusoro shavings inotariswa kureba kana hupamhi hwebhodhi. .
Sebhodhi rekugadzirisa, OSB inogamuchirwa zvishoma nezvishoma nevatengi veChinese nekuda kwesimba rayo guru (pedyo neplywood), kugadzikana kwakanaka kwechimiro, kuchengetedzwa kwezvakatipoteredza, kushandiswa kwakasiyana-siyana uye kushanda kwakanaka kwekugadzirisa, izvo zvinokurudzirawo OSB muChina. kukura kwe.
1. Kugadzirira OSB mbishi zvinhu
Kugadzirira kwezvinhu zvakasvibirira ndeimwe yenzira dzakakosha mukugadzirwa kweOSB. Mushure mekusvuura uye kubvisa tsvina kubva muhuni mbishi zvinhu, inogadziriswa kuva shavings inodiwa pakugadzirwa. Kazhinji, kureba kweshavings inoshandiswa kugadzira OSB ndeye 100-120 mm, hupamhi huri 20-50 mm, uye hupamhi hunenge 0.6 mm. .
Yakasiyana neakakura-dhayamita matanda anoshandiswa mukugadzira OSB yekunze, masosi emidziyo inoshandiswa kugadzira OSB muChina yakakura uye marudzi acho akaomarara. Iwo anonyanya kudiki-dhayamita anokurumidza kukura matanda uye nhamba huru yekugadzira masara, akadai sepoplar, eucalyptus uye matanda ebazi. Vakaona matanda akasara, nezvimwewo.
1.1. OSB refu chigadzirwa flaker inogadzira shavings yakakura
Kugadzirwa kwemashavings makuru nemhete-mhando yakareba huni flaker ndiyo gadziriro yechinyakare yegadziriro yezvinhu ye OSB yekugadzira mutsara. Kutanga, matanda acho anotumirwa kumushini wekuperera kuti upepere. Matanda akasvuurwa anopfuura nemuchina chesimbi kuti abvise matanda ane simbi. Matanda akakodzera anopinda muhuni refu Iyo yakareba huni planer batch feeder, uye ndokutumirwa kukamuri yekucheka yehuni refu planer batch nebatch kuti icheke kuita shavings.
Inowanzo shandiswa yakareba chigadzirwa planer inonyanya kusanganisira banga mhete mhando refu chigadzirwa planer, cutter musoro mhando refu chigadzirwa planer uye banga shaft mhando refu chigadzirwa planer, pakati payo kushandiswa kwebanga mhete refu chigadzirwa planer kwakawanda zvakanyanya. Banga mhete mhando refu chigadzirwa planer inoumbwa nezvikamu zvakati senge batch feeding system, alignment mechanism, kudzvanya gadziriso, nhare yekucheka kamuri uye main drive mota.
Nheyo yekushanda kwayo yakafanana neyekurodza penzura nebanga repenzura. Mushure mekunge irogi rapinda mukamuri yekucheka, kamuri yekucheka yehuni refu planer inofambira mberi ichitevedza gwara rekufambisa nekumhanya nguva dzose, uye mukati rinotenderera banga remhete zvimedu pamwe neaxis yelogi. Directional uye mapanga mapanga kudzora kureba, upamhi uye ukobvu hwemashevha. Ukobvu hwemashavings anogadzirwa nemhete-mhando yakareba huni flaker yakafanana, chimiro cheshavings yakanaka, uye kubuda kwakakwirira, iyo inokodzera mitsara yekugadzira OSB yakakura.

1.2. OSB maviri-chikamu tekinoroji kugadzira zvidimbu zvakakura zvekuveura
Kubuda kwematanho maviri OSB yakakura-yemhando yekuveura tekinoroji yakashandura nhoroondo yapfuura yekungoshandisa yakakura-dhayamita huni mukugadzirwa kweOSB. Zvidiki-zvidiki zvakaita sehuni dzebazi, huni dzakabhenda, uye zvimedu zvehuni zvinogona kushandiswa kugadzira matanda anosangana nekugadzirwa kweOSB, kugadzira OSB raw materials. kumwero wakati.
Inyanzvi yekugadzira shavings yezvikamu zviviri yakakamurwa kuita nhanho mbiri: danho rokutanga nderokupfuudza huni yemiti yakasvibirira kuburikidza neakanyatsogadzirwa chipper kuti ibudise matanda makuru ehuni nehurefu hunosvika 150 mm; danho rechipiri nderokuvheneka akachekwa machipisi makuru ehuni Bvisa tsvina, uye wozogadzira maflakes makuru nehupamhi hwe 0.6 mm uye kureba kwe 150 mm kuburikidza ne optimized ring flaker.
Kuenzaniswa neyechinyakare refu huni flaker, kureba-ukobvu reshiyo yeshavings inogadziriswa nezvikamu zviviri-chikamu chekugadzira tekinoroji yekugadzirira iri nani. Uye zvakare, kusiyana nerectangular shavings yakagadzirwa neakareba huni flaking muchina, mipendero yeshavings yakagadzirwa neaviri-nhanho flaking haina kurongeka uye kwete pamakona akarurama, uye ine zvakanyanya yunifomu tension shanduko.

2. Kuomesa OSB shavings
OSB dryer kazhinji dzinoshandisa single-channel dryer. Iyo yakajairwa yepakati-tembiricha yekuomesa tekinoroji haigone kungosangana nekuomeswa kwezvinodiwa zveyakajairwa OSB shavings, asi zvakare inoshandiswa pakuomeswa kwakasanganiswa kweshavings yakanaka uye flaky hombe shavings muOSB mbishi zvinhu zvinogona kushongedzwa.
Kuomeswa kwese kwakakamurwa kuita matanho matatu: pre-drying chikamu, chikamu chekuomesa, uye chikamu chekuenzanisa kuti ive nechokwadi chekuti hunyoro hwemashevha ekupedzisira hunodzorwa paanenge 2%. Uchishandisa kuyerera kwemhepo yemhepo yekubuda feni yemuomesi, shavings yakanaka inopfuura nemuomesi nekukurumidza nekuda kwehukuru hwavo hudiki uye huremu huremu;
Pasi pechiito chechipiri chefoshoro mukati memuomesi uye kubuda kwemhepo, shavings yepakati-kati iri muhurumende yekumisa yakasununguka kuti ipedze kuomeswa; nepo shavings yakakura ichitenderedzwa pamwe nemadziro emukati emuomesi kuti apedze kuomesa. Nguva uye nzira yakapfuura yakareba, kuitira kuti hunyoro hwemashavings hunozobuda kunze kwemuomesi hwakafanana.

3. Kurongwa kweOSB shavings
Kune marudzi maviri ekuronga mashavings, imwe ndeye kushandisa michina nzira dzekugadzirisa shavings zvichienderana nekukura kwejometri kuburikidza nemagetsi emhando dzakasiyana-siyana kana mapeji ekuseta, uye imwe ndeyekuparadzanisa shavings ine densities yakasiyana uye suspension ratios nekugadzirisa mafambiro emhepo. speed. kuronga.
Mashevha anobuda muomesa anowanzo kupatsanurwa kuita nzira mbiri, imwe ndebvu huru inodzika yakananga kubva mubhokisi rekuyerera remuomesa, uye imwe ndebvu dzakatsetseka dzinosanganiswa mugasi remuswe wekuomesa uye dzinoburitswa uye dzinounganidzwa. by the recyclone. Kuti uvandudze kushanda kwekugadzirisa, zvinowanzokurudzirwa kuparadzanisa nzizi mbiri dzeshavings dzekuongorora.
Inowanzo shandiswa mechanicha yekuongorora midziyo yekuveura ndebvu yekuongorora inosanganisira zvigubhu zvidzitiro, madhisiki sieve, uye masefa ekuzunguza. Kusarudzwa kweshavings yekuongorora michina yeOSB mitsara yekugadzira zvinoenderana nehukuru hwekugadzira uye chimiro cheshavings.

4. Kukura kweOSB shavings
Mashevha akarongwa anopinda mushevha wakaoma silo wepamusoro core layer zvichiteerana. Kuti uone kuti shavings haigoni kubhuroka mu silo, zvinhu zvacho zvinobudiswa zvakanaka uye chimiro cheshavings hachina kukuvadzwa, silo yekuchengetedza shavings ndeye yakanyatsogadzirirwa yakatwasuka zvinhu. warehouse.
Kune tsvimbo yekutsigira pakati peiyo roller glue yekusanganisa muchina, pairi imwe nhamba yeatomizing misoro inogadzirwa uye yakaiswa), glue, parafini emulsion, kurapa agent uye zvimwe zvinowedzera zvinosanganiswa nemashavings mumushini wekusanganisa glue kuburikidza. musoro weatomizing.
Bhara rekutungamira rakaiswa pamadziro emukati meglue mixer rinounza simba recentrifugal remashevha anotenderera necylinder kuenda kunzira yewachi na11:00. Iyo shavings inopedza kuyera panguva yemahara yekudonha maitiro, uye mashevha ari muglue musanganiswa anoteera kutungamira kweglue musanganiswa. Kutenderera kwecylinder kunounzwa kumusoro nekudzika kakawanda kuti idzokororwe saizi.
5. Pavement yeOSB shavings
Iyo yepamusoro-soro shavings mushure mekusanganiswa kweglue inotumirwa kune yepamusoro core layer metering silo yechiteshi chekugadzira, uye yozoiswa nemusoro wega wega paving. Iyo yechinyakare OSB pavement ndeye 3-layer chimiro pavement, kureva, yepamusoro uye yepasi pepamusoro peturu uye yepakati layer. Pakati pavo, nzira yekugadzira yekumusoro uye yakadzika pamusoro pematanho inotungamirira paving munzira yakareba, uye yakafara uye yakareba shavings yakakura yakanyatsoiswa pamusoro pepamusoro; iyo nzira yekugadzira yeiyo core layer ndeye yakachinjika inotungamira paving, uye iyo yakakamurwa zvakatsetseka diki-diki shavings inoiswa pane yepakati layer.
Chiyero chekuyeresa chinogona kubatanidzwa pazasi pe shavings metering silo, uye iyo metering bhandi chiyero chakaiswa pazasi peiyo pavement metering silo inogona kugadzirisa huwandu hwekudyisa nenguva zvichienderana nekutsauka kwe shavings bulk density shanduko, kuitira kuti zadzisa kutonga kwakaringana, iyo inopedzwa zvakananga nemusoro wepaving Iyo chipboard pavement inoumba iyo slab chimiro.
