Cov ntoo ua lag luam tau ntim nrog ntau yam khoom lag luam. Qee lub sij hawm nws tsis yooj yim to taub tias ntau cov ntaub ntawv sib txawv hauv lub cev thiab cov yam ntxwv thev naus laus zis tuaj yeem ua rau tib hom. Fiberboard (nws yog hardboard lossis tsuas yog ib daim ntawv ntawm fiberboard) yog ib qho ntawm ntau yam ntoo sib xyaw ua ke.

Hauv tebchaws Russia, feem ntau ntawm cov rooj tog zaum tseem ua los ntawm cov phaj no. Cov khoom siv no tseem siv hauv kev tsim cov tsheb laij teb. Thiab hauv kev tsim kho kev lag luam, kev faib khoom tau tsim los ntawm fiberboard hauv chav, siv rau kev ua tiav ua tiav ntawm qab nthab, nws tuaj yeem tso rau hauv pem teb. Tsis ntev los no, laminated fiberboard tau tshwm sim, uas yog siv rau kev kho kom zoo nkauj. Cov khoom muaj qhov sib txawv sib txawv thiab qib ntawm kev tiv thaiv ya raws.

Peculiarities

Cov khoom siv no, tsim ua ntawv, yog tau los ntawm kev tso cov ntoo ntoo hauv daim ntawv ntawm cov ntaub pua plag ntawm cov tuab tuab . Yeej, rau kev tsim khoom ntawm fibreboard, cov khib nyiab tau los ntawm kev siv tshuab ntoo tau pib siv. Niaj hnub no, tag nrho cov ntoo tuaj yeem ua tiav rau qhov no.

Cov quav thiab sawdust yog thawj zaug sib xyaw nrog cov khoom siv dag thiab cov tshuaj tua kab mob. Tom qab ntawd nws yuav siv sijhawm qee lub sijhawm los txhawm rau txhaws cov khoom nyoos los ntawm kev nias kub. Raws li cov ntaub ntawv raug nias li cas, Fiberboard tau muab faib ua ob peb qib.

1. Ib nrab-khoom (ib yam dab tsi zoo li daim duab tuab). Lawv qhov ceev yog 400 kg / m3.
2. Khoom (muaj zog, tsis muaj pore). Ceev 850 kg / m3 - txiav txim los ntawm GOST.
3. Superhard (hnyav heev). Qhov ntom tshaj 950 kg / m3, nws txwv tus nqi yog 1100 kg / m3.
4. Rwb thaiv tsev. Hom fibreboard no yog qeb ntawm qhov tsawg tshaj plaws ntom ntom thiab tsis siv nyob rau hauv qhov chaw uas xav tau kom tiv taus txawm tias muaj kev nyuab siab me me hauv kev tsim khoom. Ceev tsis ntau tshaj 250 kg / m3.
5. Tiav thiab insulating. Cov fibreboard no tseem tsis tau tsim rau kev thauj khoom. Nws sab xub ntiag tuaj yeem siv los kho chav. Qhov ntom ntawm slab yog ib puag ncig 250 kg / m3.
6. Mos (nco txog kev xav). Lawv qhov ceev tshaj yog 100 kg / m3. Cov khoom siv no yog thawj tus neeg sib tw rau GKL, vim nws tau ua tiav zoo rau kev ua tiav cov plag tsev.

Fiberboard yog qhov pheej yig, thiab yog tias koj siv nws tsuas yog qhov chaw tsim khoom qhia, tom qab ntawd koj tuaj yeem tau txais cov dej noo-tiv taus, ua haujlwm tau zoo thiab cov khoom tsim tau zoo rau cov nyiaj tsim nyog. Txawm li cas los xij, niaj hnub no nws pheej yig dua los yuav cov khoom uas muaj ntoo ntau dua li cov khoom ntoo qhuav.

Kev siv tshuab ntau lawm

Fibreboards yog ua los ntawm ntoo. Yuav kom meej dua, tsis yog los ntawm ib qho array, tab sis los ntawm cov khoom pov tseg uas tseem tshuav thaum ua cov ntoo ntawm sawmills thiab lwm yam ntoo ua lag luam . Ib qho ntxiv, cov qauv ntawm cov khoom yuav suav nrog siv cov ntawv thiab nws cov pov tseg, lwm yam khoom lag luam uas muaj cellulose. Tom qab zom cov khoom sib xyaw, cov khoom siv tau nrawm rau hauv cov nplais thiab qhuav. Txhawm rau ua kom lub rooj tsav xwm tiv taus cov dej noo, ntau yam kev tshem tawm thiab cov tshuaj ua kom nrawm tau ntxiv rau cov khoom siv fibrous semi-tiav.

Cov txheej txheem tsim khoom siv fiberboard tau muab faib ua ob peb theem:

1. muab cov ntoo pov tseg pov tseg pov tseg, tom qab ntawd cov khib nyiab thiab cov xuab zeb raug tshem tawm ntawm lawv los ntawm txoj kev nqus cov nroj tsuag;
2. tom qab ntawd ntawm lub tshuab centrifuges siv cov tshuab hluav taws xob, cov khoom hlau raug tshem tawm los ntawm cov qauv sib xyaw;
3. tom qab ntawd cov chips raug xa mus rau kev sib tsoo, uas tuaj yeem yog ob qho loj thiab me me, raws li cov xwm txheej rau kev siv cov laminated fiberboard;
4. nyob rau hauv tus defibrator, kneading yog nqa tawm nrog ntxiv ntawm resins, polymers thiab paraffins.

Thaum ua tiav cov haujlwm no tsim ntawm laminated fibreboard tuaj yeem ua kom qhuav lossis ntub. Hauv kev lag luam niaj hnub no ntau dua, txoj hauv kev qhuav tau siv, tsuas yog nws tsis muaj kev nyab xeeb ib puag ncig dua li ntub ib qho. Qhov no cuam tshuam nrog kev nce cov ntsiab lus formaldehyde hauv cov ntawv sib xyaw.

Cov txheej txheem lamination muaj ntau tus yam ntxwv

• Tom qab kev npaj ua haujlwm saum npoo av, cov nplais raug xa mus rau lub tshuab kub nias, uas cov dej ntxhia ua kom sov tau nthuav tawm tas li kom tswj tau qhov kub thiab txias.
• Muab txuas rau hauv xovxwm yog ib daim ntawv uas muaj cov qauv txheej uas txiav txim siab hom kev luam yav tom ntej embossed (ntoo pores, tawv nqaij tawv, tawv cib, thiab lwm yam).
• Cov ntawv fiberboard tau npog nrog cov yeeb yaj kiab tshwj xeeb melamine nrog qib qis ntawm kev ua kom tawv, tom qab uas kub xovxwm luam tawm nws ntawm cov nplaim hluavtaws.
• Nyob rau hauv kev cuam tshuam ntawm kev kub siab thiab kub, tawg tawg ntawm melamine-based resins tau nqa tawm, uas nthuav tawm mus rau saum npoo ntawm cov khoom, lo rau nws yam tsis siv cov nplaum
• … Yog tias tsim nyog, fiberboard tuaj yeem laminated ntawm ob sab.

Txoj kev impregnation no tau lees tias cov dej tsis kam tiv taus cov khoom, sab nrauv zoo nkauj heev thiab ua haujlwm tau zoo thiab yam ntxwv zoo.

Qhov xav tau siv cov cuab yeej kim thiab lub zog xav tau kom tau txais ib chav ntawm cov khoom coj mus rau qhov tseeb tias tus nqi ntawm laminated fiberboard tsis yog txhua qhov nyiaj txiag. Ib qho ntxiv, nws nyob ntawm qhov tuab ntawm cov txheej txheem txheej txheem, qhov tshwj xeeb ntawm cov xim thiab qhov tob ntawm cov xim embossing.

Thickness thiab xim

Daim ntawv thov txheej txheej zoo nkauj (lamination) tsis muaj kev cuam tshuam dab tsi ntawm cov tuab tuab ntawm lub rooj tsavxwm. Raws li lub hom phiaj ntawm cov khoom, nws qhov tawv thiab tuab tau xaiv. Cov tshuab tsim khoom no ua rau nws muaj peev xwm tsim tau LDVP nrog tuab ntawm 2, 5 txog 4 hli.

Kev tsim cov txheej txheem nyuaj thiab superhard ntawm fibreboard muab rau cov vaj huam sib luag txog 12 hli tuab, uas tau siv rau ntawm phab ntsa vaj huam sib luag. Txawm li cas los xij, cov hnoos qeev tuaj yeem ua rau tuab 2.5 hli, 3 hli, 4 hli thiab 6 hli. Ib qho ntxiv, raws li lub hom phiaj siv, qhov ntom ntawm fibreboard kuj tuaj yeem sib txawv, tsis hais txog qhov tuab li cas.

Painting ntawm fibreboard ua tiav nrog cov xim pleev xim dej raws cov polyacrylates (feem ntau yog polymers ntawm butyl, ethyl thiab methyl acrylates), ntxiv rau cov polymers ua cov yeeb yaj kiab. Cov xim tuaj yeem sib txawv - zoo li tsis pom zoo (nyiaj, titanium, tob dub, dawb, xim av), thiab zoo nkauj muaj xim (liab, ntuj xiav, neon ci txiv qaub). Kev kho kom zoo nkauj yog kho los ntawm kev siv lub tshuab ua kua, uas tau siv ob peb txheej txheej ntawm cov kua roj vanish, txhua tus ntawm lawv kom qhuav kom qhuav los tiv thaiv cov fibreboard los ntawm khawb.

Qhov sib txawv ntawm laminated chipboard

Laminated fibreboard (LFB) yog tsim los siv tib lub tshuab ib yam li laminated chipboard (LFB) . Qhov sib txawv yog tias chipboard yog tsim los ntawm kev nias shavings sib xyaw nrog cov resins, thaum fibreboard muaj sawdust. Tsuas yog lawv thawj zaug tsoo rau hauv daim me me, thiab ua ntej raug nias ntawm cov xovxwm, lawv tau ua tiav nrog cov pa. Cov laug cam no yog cov tuab dua li chipboards thiab hloov pauv tau ntau dua.

Tsis muaj txheej txheej zoo nkauj ntawm daim tawv fibreboard, nws tau xuab zeb ntawm ib sab kom cov nplaim zoo li tus. Nws raug nquahu kom siv cov phaj ntawd hauv cov chaw uas tsis pom rau lwm tus. Qhov no ua rau nws muaj peev xwm txuag tau qee cov nyiaj, txij li cov fiberboard ntxhib yog qhov pheej yig dua li cov khoom siv dai kom zoo nkauj.

Nws siv qhov twg?

Kev siv laminated fibreboard nyob ntawm tus yam ntxwv ntawm lub vaj huam sib luag. Nws muaj lub suab rwb thaiv tsev zoo heev, thiab vim li no nws thiaj nquag siv hauv cov chav uas nws yuav tsum tau muab lub suab rwb thaiv tsev tshaj plaws - kaw suab studio, chav tshaj tawm xov tooj cua . Fiberboard tau ua kom pom tseeb nws tus kheej hauv chaw ua haujlwm thiab tsev kawm ntawv , qhov twg nws ua tiav zoo nrog lub luag haujlwm ntawm lub suab rwb thaiv tsev.

Qhov ua kom zoo thiab du ntawm lub vaj huam sib luag nrog qhov twb tau thov kev ntxhib los mos ntawm ntoo, granite, marble lossis lwm yam khoom siv zoo meej rau tsim sab hauv ob qho tib si hauv kev sib xyaw nrog lwm cov ntaub ntawv, thiab thaum ntsib lub ntsej muag tshwj xeeb fiberboard. Qhov no feem ntau yog siv rau hauv pem teb thiab phab ntsa nrog qhov ua tsis tau zoo.

Qhov tshwj xeeb ntawm kev siv cov phaj, raws li cov txheej txheem kev ntsuas, muaj tus lej ntawm qhov tsis sib xws

1. Hom mos muaj porosity siab thiab yog li ntawd qhov ntom ntom. Lawv siv yog tsim nyog rau kev faib thiab phab ntsa tom qab ntawm rooj tog.
2. Cov khoom ib nrab yog qhov kev txiav txim siab ntawm qhov muaj zog dua, tab sis lawv tau tsim tsuas yog rau sab nraub qaum ntawm cov rooj tog hauv rooj tog.
3. Nyuaj thiab nyuaj heev. Hom fiberboard no muaj zog tshaj plaws. Hauv qhov no, cov qhov rooj, lub qhov rooj yog tsim los ntawm nws, thiab lawv tau teeb tsa hauv av.
4. Kev ua tiav thiab rwb thaiv tsev, raws li txoj cai, yog laminated. Ib qho kev ntxhib los mos tau thov rau lawv saum npoo. Cov fibreboard no tuaj yeem siv rau qhov rooj, muab faib thiab tejzaum nws yog cov khoom siv hauv kev tsim cov khoom rooj tog.

Ntoo-fiber ntau vaj huam sib luag, uas muaj txheej txheej ntawm ib sab lossis ob sab, yog cov khoom cog lus uas yeej tsis poob nws qhov tseeb . Lawv yuav raug siv ob qho tib si ntsib kev ua haujlwm thiab tsim cov rooj tog zaum, tsim kev faib ua feem thiab cov pa cua, thiab tshem tawm cov qab nthab.

Laminated fibreboard yuav tsum xav tau tiag tiag thaum ua kho thiab ua haujlwm, qhov tseem ceeb tshaj plaws yog qhov kev xaiv raug thiab paub txog cov txheej txheem yuav txiav thiab nteg nws li cas.
