I-OSB yenziwe ngamaplanga amakhulu eemilo ezichaziweyo kunye nobukhulu emva kokuncamathisela kunye nokuyibeka ngendlela ehambelanayo, kwaye emva koko icinezelwe ngokushushu ukwenza ibhodi yesakhiwo se-multi-layer, kunye ne-shavings yomhlaba ihambelana nobude okanye ububanzi bebhodi. .
Njengebhodi yesakhiwo, i-OSB iyamkelwa ngokuthe ngcembe ngabathengi baseTshayina ngenxa yamandla ayo aphezulu (kufuphi neplywood), ukuzinza okuhle kwe-dimensional, ukukhuselwa kwendalo, uluhlu olubanzi lwezicelo kunye nokusebenza kakuhle kokusebenza, okukhuthaza i-OSB e-China. Uphuhliso lwe.
1. Ukulungiswa kwezinto ze-OSB ekrwada
Ukulungiswa kwezinto ezikrwada yenye yeenkqubo eziphambili ekuvelisweni kwe-OSB. Emva kokucoca kunye nokususa ukungcola kwimpahla eluhlaza yokhuni, icutshungulwa kwi-shavings efunekayo kwimveliso. Ngokuqhelekileyo, ubude bee-shavings ezisetyenziselwa ukuvelisa i-OSB yi-100-120 mm, ububanzi buyi-20-50 mm, kwaye ubukhulu bu malunga ne-0.6 mm. .
Ngokwahlukileyo kwiilogi ezinkulu ezisetyenziselwa ukuveliswa kwe-OSB yangaphandle, imithombo yezinto ezisetyenziselwa ukuvelisa i-OSB e-China zibanzi kwaye iintlobo zinzima. Zizigodo ezikhula ngokukhawuleza ezinobubanzi obuncinci kunye nenani elikhulu leentsalela zokulungisa, ezifana ne-poplar, i-eucalyptus kunye nemithi yesebe. Ubone iintsalela zamaplanga, njl.
1.1. I-OSB i-flaker yemveliso ende ivelisa ukucheba okukhulu
Ukuveliswa kwee-shavings ezinkulu nge-ring-type i-flaker yomthi ende yinkqubo yendabuko yenkqubo yokulungiswa kwezinto zomgca wokuvelisa we-OSB. Okokuqala, izigodo zithunyelwa kumatshini wokucoca ukuze uhlambuluke. Izigodo ezihlanjululweyo zidlula kwi-detector yesinyithi ukususa izigodo eziqulethe isinyithi. Izigodo eziqeqeshiweyo zingena kwiplanga elide I-wood planer batch feeder ende, kwaye emva koko ithunyelwe kwigumbi lokusika lebhetshi yeplani yomthi ende ngebhetshi ukugawula iitshevi.
Izicwangcisi zemveliso ezisetyenziswa ngokuqhelekileyo zibandakanya umsesane wohlobo lomsesane omde wemveliso, umsiki wentloko yohlobo lweplani yemveliso ende kunye nohlobo lweplani yemela yemela emide, phakathi kwayo ukusetyenziswa kweplani yentsimbi ende kakhulu. Isicwangcisi semveliso ye-Knife ende yenziwe ngamacandelo amaninzi anje nge-batch feeding system, indlela yokulungelelanisa, into ecinezelayo, igumbi lokusika elihambayo kunye ne-motor drive ephambili.
Umgaqo wayo wokusebenza ufana nokulola ipensile ngemela yepensile. Emva kokuba ilogi ingene kwigumbi lokusika, igumbi lokusika leplani yomthi ende liqhubela phambili ecaleni komgaqo kaloliwe ngesantya esingaguqukiyo, kunye nezilayi zangaphakathi ezijikelezayo zomese ecaleni kwe-axis yelogi. Iimela ezikhokelayo kunye neziko ukulawula ubude, ububanzi kunye nobukhulu beetshefu. Ubunzima bee-shavings eziveliswa yi-ring-type long wood flaker ifana ngokufanayo, ukumila kwee-shavings kulungile, kwaye imveliso iphezulu, ifanelekile kwimigca yokuvelisa i-OSB enkulu.

1.2. I-OSB iteknoloji yamacandelo amabini ukuvelisa iziqwenga ezinkulu zokucheba
Ukuvela kwemigangatho emibini ye-OSB iteknoloji yokuvelisa i-shaving enkulu iye yatshintsha imbali yangaphambili yokusebenzisa kuphela umthi omkhulu we-diameter kwimveliso ye-OSB. Izinto ezincinci ezinje ngamaplanga esebe, iinkuni ezigobileyo, kunye nezilaphu zomthi ezisahliweyo zingasetyenziselwa ukusetyenzwa kweeplanga ezidibana nemveliso ye-OSB, ukwenza izinto ezikrwada ze-OSB Umda wandisiwe, oye wanciphisa ukunqongophala kwezinto ezikrwada kubavelisi be-OSB. umlinganiselo othile.
Itekhnoloji yokulungiswa kwe-shavings yamacandelo amabini ihlukaniswe ngamanyathelo amabini: isinyathelo sokuqala kukudlula izinto eziluhlaza zokhuni ngokusebenzisa i-chipper eyenzelwe ngokukodwa ukuvelisa i-chips ezinkulu zokhuni ezinobude obumalunga ne-150 mm; Inyathelo lesibini kukukhusela iitshiphusi zokhuni ezisikiweyo Susa ukungcola, kwaye emva koko uqhube iiflakes ezinkulu ezinobunzima obuyi-0.6 mm kunye nobude obumalunga ne-150 mm ngokusebenzisa i-ring flaker ephuculweyo.
Xa kuthelekiswa ne-flaker yomthi omde, umlinganiselo wobude bobude be-shavings ecutshungulwa yi-teknoloji yokulungiselela ukucheba ngamacandelo amabini kungcono. Ukongeza, ngokungafaniyo ne-shavings yexande elungiselelwe ngumatshini omde wokutshisa iinkuni, imiphetho yeesheyi ezilungiselelwe ngamanqwanqwa amabini aqhelekileyo kwaye azikho kwii-angles ezifanelekileyo, kwaye zineenguqu ezilinganayo zoxinzelelo.

2. Ukomiswa kweetshevi ze-OSB
Izomisi ze-OSB ngokubanzi zisebenzisa izomisi zetshaneli enye. Itekhnoloji yokumisa iqondo lobushushu eliphakathi ayinakuhlangabezana kuphela neemfuno zokomisa ii-shavings ze-OSB eziqhelekileyo, kodwa zikwasetyenziselwa ukomiswa okuxutyiweyo kwe-shavings ecocekileyo kunye ne-flaky shavings enkulu kwi-OSB yezinto eziluhlaza ezinokuhonjiswa.
Yonke inkqubo yokumisa ihlulwe ibe ngamanqanaba amathathu: icandelo lokumisa kwangaphambili, icandelo lokumisa, kunye necandelo lokulinganisa ukuqinisekisa ukuba umgangatho womswakama we-shavings wokugqibela ulawulwa malunga ne-2%. Ukusebenzisa i-airflow ye-outlet fan of dryer, i-shavings emihle idlula kwi-dryer ngokukhawuleza ngenxa yobukhulu bayo obuncinci kunye nobunzima obulula;
Ngaphantsi kwesenzo esiphindwe kabini sefosholo ngaphakathi kwesomisi kunye ne-airflow, i-shavings ephakathi nendawo ikwimeko yokumiswa kwamahhala ukugqiba ukomisa; ngelixa i-shavings enkulu ijikeleziswa ecaleni kodonga lwangaphakathi lwesomisi ukugqiba ukomisa. Ixesha kunye nomzila ogqithisiweyo zide kakhulu, ukwenzela ukuba umxholo wokufuma we-shavings ophuma ekugqibeleni kwi-dryer ufana.

3. Ukuhlelwa kweeshevi ze-OSB
Kukho iindlela ezimbini zokuhlenga ukucheba, enye kukusebenzisa iindlela zoomatshini ukuhlenga ukucheba ngokwesayizi yejometri ngokusebenzisa iigridi zeendawo ezahlukeneyo zokuvula okanye ukuseta izikhewu, kwaye enye kukwahlula ukucheba ngoxinaniso olwahlukeneyo kunye nemilinganiselo yokumiswa ngokuhlengahlengisa ukuhamba komoya. isantya. ukuhlela.
Ukucheba okuphuma kwi-dryer ngokuqhelekileyo kwahlulahlula ngeendlela ezimbini, enye i-shavings enkulu ehla ngokuthe ngqo kwibhokisi yokukhupha i-dryer, kwaye enye i-shavings ecocekileyo exutywe kwigesi yomsila wokomisa kwaye ikhutshwe kwaye iqokelelwe. ngenkanyamba yokurisayikilisha. Ukuze kuphuculwe ukusebenza kakuhle kokuhlelwa, ngokuqhelekileyo kucetyiswa ukuba ukwahlule imijelo emibini yokutsheva ukuze kuhlolwe.
Izixhobo zokuhlola ezisetyenziswa ngokuqhelekileyo zokucoca iitsheva ziquka izikrini zomgqomo, iisefu zedisc, kunye neesefu ezijingayo. Ukukhethwa kwezixhobo zokuhlola i-shavings kwimigca yokuvelisa i-OSB kuxhomekeke kumthamo wokuvelisa kunye nokuma kweeshefa.

4. Ubungakanani be-OSB shavings
Ukutsheva okuhleliweyo kungena kwisisele esomileyo sokutsheva somgangatho ongaphezulu ngokulandelelanayo. Ukuze kuqinisekiswe ukuba i-shavings ayifaki ibhuloho kwi-silo, izinto eziphathekayo zikhutshwe ngokufanelekileyo kwaye ukumila kwe-shavings akukonakali, i-silo yokugcina i-shavings yinto ekhethekileyo eyenzelwe i-horizontal. indawo yokugcina impahla.
Kukho intonga yenkxaso embindini we-roller glue yokuxuba umatshini, apho inani elithile leentloko ze-atomizing zenzelwe kwaye zifakwe), iglue, i-emulsion yeparafini, i-agent yokunyanga kunye nezinye izongezo zixutywe kunye nokucheba kumatshini wokuxuba iglu intloko atom.
Ibha yesikhokelo efakwe eludongeni lwangaphakathi lomxube weglue izisa i-centrifugal force ye-shavings ejikelezayo kunye ne-cylinder ukuya kwicala le-clockwise ngo-11: 00. I-shavings igqiba ukulinganisa ngexesha lenkqubo yokuwa kwamahhala, kwaye i-shavings kwi-glue mixer iya kulandela isalathiso somxube weglue. Ukujikeleza kwe-cylinder kuziswa phezulu naphantsi amaxesha amaninzi ukwenzela ukulinganisa okuphindaphindiweyo.
5. Ipavumente yeetshefu ze-OSB
I-surface shavings engundoqo emva kokuxutywa kweglue ithunyelwa kumphezulu ongundoqo we-metering silo yesikhululo sokugalela, kwaye emva koko igalelwe intloko nganye yokugalela. Umgangatho we-OSB wendabuko yi-3-layer structure pavement, oko kukuthi, iileyile eziphezulu kunye nezantsi kunye ne-core layer. Phakathi kwabo, indlela yokukhangela imigangatho ephezulu kunye nesezantsi iyindlela yokuqondisa kwindlela yobude, kwaye i-shavings ebanzi kunye nede emide ifakwe ngokuthe ngqo kwinqanaba eliphezulu; indlela yokupeyinta yomaleko ongundoqo kukugalela okuthe tyaba okuthe tye, kwaye iitshewuli ezicandiweyo ezincinci ezicandiweyo zigangathiwe kumaleko angundoqo.
Iyunithi yokulinganisa inokudityaniswa ezantsi kwesisele semitha yeshavings, kwaye isikali sebhanti yokulinganisa efakwe ezantsi kwesayile yemetha yendlela egangathiweyo singalungelelanisa isixa sokutya ngexesha ngokutenxa kwishavings yokutshintsha kobuninzi bobuninzi, ukuze fezekisa ulawulo oluchanekileyo, olugqitywe ngokuthe ngqo yintloko yokupakisha I-chipboard pavement yenza isakhiwo se-slab.
