Nekukurumidza kusimudzira hupfumi hwenyika yangu uye nekuvandudzwa kwemararamiro evagari vemumaguta nemaruwa, yave fashoni yakakurumbira yekushandisa kuita mukati mekushongedza kwemukati uye kuvandudza fenicha.Nekudaro, mapaneru ane huni anoshandiswa zvakanyanya sezvigadziko zvekushongedza mukati uye maindasitiri efenicha, saka pane dambudziko rekusvibiswa kwe formaldehyde.Kare, mari yehupfumi hwevanhu yaive yakaderera, yakawanda yekushongedza kwemukati yaingoitwa zvishoma, uye fenicha yaiwanzo gadziridzwa mune shoma shoma, saka kusvibiswa kwe formaldehyde kwaisave kwakakurumbira uye kwaigona kushivirirwa.
Mazuva ano, zvakajairika kune avo vanotamira mumusha mutsva kuti vagadzirise zvizere uye kugadzirisa fenicha.Nenzira iyi, kuunganidzwa kwe formaldehyde volatilization kunowedzera zvakanyanya, kusvika padanho risingatsungirike, kuchiisa mungozi nzvimbo yekugara yevashandisi.Nechikonzero ichi, gakava pakati pedhipatimendi rekushongedza nemushandisi rave dambudziko remagariro, uye zvigadzirwa zvekushongedza kana fenicha zvinobva kumusika, uye hapana nzira yekuigadzirisa.Nekuvandudzwa kweruzivo rwekuchengetedzwa kwezvakatipoteredza pasi rose, kusvibiswa kunokonzerwa negasi reformaldehyde kwasvika pamwero unofanirwa kucherechedzwa.Nechikonzero ichi, sainzi uye tekinoroji mushandi akashanda akawanda matanho uye anoedza kugadzirisa.Zvakadai sekuvandudza nzira inonzwisisika ye urea uye formaldehyde, kana kunyange kushandisa formaldehyde scavengers, nezvimwewo, asi haisi mhinduro yakasimba.Uye zvakare, zvinhu zvekurongedza zvezvimwe zvinhu, senge chikafu, tii, fodya, nezvimwe, hazvibvumire kuvapo kwe formaldehyde.Kare, huni hwepanyama hwainyanya kushandiswa.Nekuda kwekushandiswa kwemutemo wenyika wekuchengetedza zviwanikwa zvemasango, kushandiswa kwematanda ekurongedza zvinhu kwakarambidzwa.Paunenge uchitsvaga zvimwe zvinhu, huni-based panels ndiyo yekutanga sarudzo.Nekudaro, zvakaoma kuziva nekuda kwekusvibiswa kwe formaldehyde.Zvese izvi zvinoita kuti kudiwa kwekusvibiswa-kusina "green huni-based panels" pane ajenda.Kunobva kuburitswa kwe formaldehyde gasi ndiko kunamira kunoshandiswa mukugadzirwa kwemapuranga-based panels - urea-formaldehyde resin.Mukana wakakurisa werudzi urwu rwekunamira nderekuti kwakabva zvinhu mbishi zvakawanda, kuita kwakanaka, mutengo wakaderera, uye hapana chinotsiva parizvino.Nekudaro, urea-formaldehyde resin inoganhurwa neiyo synthesis process.Hazvina mhosva kuti fomula inovandudzwa sei, iyo kemikari yekuita haigone kuve yakakwana.Munguva yekugadzirwa uye kushandiswa kwechigadzirwa, pane nguva dzose dambudziko rekuwedzera kwe formaldehyde yakasunungurwa uye yakagadziriswa, chete huwandu.Kana iyo synthesis process iri kumashure, gasi rakawanda reformaldehyde richaburitswa.Pakati pemabhizinesi mazhinji-akavakirwa pamapuranga munyika yedu, tekinoroji yekugadzira urea-formaldehyde resin ndeyechinyakare, saka hazvishamise kuti mapaneru ane huni anopinda mumusika anokonzera kusvibiswa kwakakomba.Iko hakuna formaldehyde-yemahara glue marudzi, asi ingave iyo glue sosi ishoma kana mutengo unodhura.Maererano nekugadzirwa kwemazuva ano kwemapuranga-based panels munyika yangu, gore negore kushandiswa kwemvura yakanamatira inenge mamiriyoni matatu emamiriyoni, izvo zvakaoma kusangana.Uye iyo yakachipa yekugadzira resin munguva dzazvino ingori urea glue.
Zvakaoma kuyananisa kupokana pakati pekudzikisa kusvibiswa, mutengo uye glue sosi munguva pfupi iri kutevera.Naizvozvo, nyanzvi dzekumba nekune dzimwe nyika dziri kuongorora imwe nzira, ndiko kuti, kugadzira mapaneru ane huni ane glue-isina maitiro.Anopfuura makore makumi matatu apfuura, Soviet Union neCzech Republic vakapedza kudzidza kugona kwedzidziso uye tekinoroji, uye Czech Republic yakaitawo diki-diki kugadzirwa.Handizivi kuti sei ndisina kuramba ndichiidzidza?Zvichida chikonzero chikuru ndechekuti kusvibiswa kwekusvibiswa hakuna kukwezva kutarisa kwevanhu panguva iyoyo, uye simba rekufambisa rekudiwa rakarasika, saka rakanga risingadi kuwedzera kuvandudza nzira yekugadzira.
Iye zvino kuziva nezvekuchengetedzwa kwezvakatipoteredza kwasvika pakakwirira zvisati zvamboitika, uye panguva imwechete, mukuita, vashandisi havagoni kutsungirira.Zvikasadaro, Japan yaisazoburitsa formaldehyde scavenger.Naizvozvo, nyanzvi dzekumba nekune dzimwe nyika dzakabhadhara zvakanyanya kutsvagurudzo yenyaya iyi, vakatora nzira dzakasiyana dzehunyanzvi, uye vakawana mimwe mibairo zvichiteerana.Nekudaro, hapana kana chimwe chazvo chakagadzira kugadzirwa kwakakura kuita kuti zvigadzirwa zvipinde mumusika.Iko kuvandudza kweglue-isina huni-yakavakirwa mapaneru ndiyo inonyanya kushanda nzira yekugadzirisa kusvibiswa kwezvakatipoteredza, uye zvakare inzira yekusimudzira.Parizvino, pane makwikwi pakati pehunyanzvi hwekuvandudza tekinoroji uye nguva, ani nani ane yepamusoro-soro, yakapusa uye yakapusa-yekusimudzira tekinoroji ndiye achava wekutanga kuumba chibereko uye kutora musika.
Zvinoenderana neiyo gluing dzidziso yekuti mafiber ekudyara anogona kuzvinamatira, izvo zvakasimbiswa nevakatangira, kuburikidza nekudzokororwa bvunzo uye kuenderera mberi nekugonesa, budiriro yakaitwa mukugadzira isiri-glue fiberboard.Kiyi yekukunda ndeye kuvandudza mashandiro eiyo isiri-glue bhodhi uye kurerutsa maitiro ekushanda Inogona kushandisa iripo yepakati density fiberboard mutsara wekugadzira kugadzira glueless fiberboard pasina kuita chero shanduko kune ese ekugadzira michina (chete yekugadzira glue michina. haichashandiswi).Simba remuchina chechigadzirwa rakaenzana kana kukwira kupfuura reyakajairika particleboard, uye kuita kwekusapinda mvura kwakafanana nekweurea fiberboard.
Sezvo mvura ichishandiswa se "adhesive", iyo yekuzvinamira simba pakati pe fiber inopedzwa panguva yekupisa yekutsikirira, saka hunyoro hwemukati hwe slab hwakakwira kupfuura iyo ye sizing slab, uye kupisa kutenderera kunofanirwa kuwedzerwa. kuve nechokwadi chekuti maitiro emakemikari anopedzwa zvizere, nekudaro achikanganisa kugadzirwa kwepakutanga, asi haana chaanoita pakuita kwehupfumi chaihwo.
1. Kuchengetedza mari yekunamatira ibhenefiti yakananga uye inowedzera purofiti.
2. Chigadzirwa chacho hachina chigadziko chakasimba, sanding shoma, kushandiswa kwesimba shoma, uye kuderera kwesimba rekushandisa uye abrasive bhanhire mari.
3. Yakawanda yemvura iri mu slab inotamirwa kumuchina kuti ibude, kuitira kuti chikamu che convective heat transfer in the dryer chinoshandurwa kuva chinosangana nekupisa kupisa, kushanda kwekushisa kunovandudzwa, uye kushandiswa kwemarasha kunoderedzwa.Aya mamwe mabhenefiti.
Pazvinhu zvitatu izvi chete, kunyange kana gore negore kubudiswa kwakaderedzwa kubva pa30,000 m3 kusvika ku15,000 kusvika ku20,000 m3, inogona kuramba ichigadzira purofiti ye3.3 mamiriyoni kusvika 4.4 mamiriyoni eyuan pagore (zvichienderana nemutengo weglue).Zvakare, mushure mekunge kuburitsa kwadzikiswa, zviwanikwa uye kushandiswa kwesimba zvinoderedzwawo ne30% kusvika 50%, kurasikirwa kwemidziyo uye mutengo wekugadzirisa zvakare wakaderedzwa, uye mari yese yekushanda inogarwa zvakare yakaderedzwa.Iyi ndiyo indirect benefit inogadzirwa.Naizvozvo, purofiti yakazara haina kuderera pane yepakutanga yakabuda, kana kunyange yakakwirira.Izvo zvakare zviri nyore kwazvo kuchengetedza yekutanga kuburitsa, nekuti kugadzirwa kwechigadzirwa chega chega chisati chachinja, saka zvinogona kuitwa nekuwedzera mushini wekupisa uye nzira yekufambisa, kana kushandura huwandu hwematanho. hot press .Iyi mari yekuvandudza inodiwa.
Mukana wakakurisa weglueless fiberboard ndiko kubviswa kwakazara kwekusvibisa masosi uye mutengo wakaderera, uye kushandiswa kwayo kunogona zvakare kuwedzerwa kurongedza zvinhu zvezvimwe zvinhu zvisingabvumidze kusvibiswa.Kukanganisa kwechisikigo kweglueless fiberboard: inonamirwa ne-self-adhesive simba inogadzirwa nekemikari kuita kwemvura uye fiber mamorekuru.Mafibhi anofanirwa kunge ari padhuze, zvikasadaro adhesion ichadzikiswa, saka density yakakwira kupfuura yeyakajairika saizi MDF.Ichi chikanganiso hachioneki kana mapepa matete akagadzirwa.
