Pawg Lamination

Vaj huam sib luag lub ntsej muag tseem hu ua cov vaj huam sib luag prelaminated nrog cov xim sib txawv lossis cov qauv duab. Melamine impregation ntawv yog pua chaw rau panels zoo li MDF, balcle board, thiab tom qab ntawd muaj kev kub siab thiab muaj kev kub siab. Melamine daim ntawv nto tsis tsuas yog txhim kho lub vaj huam sib luag lub zog, nruj thiab kub tsis kam, tiv thaiv kev tiv thaiv ib puag ncig, kev noj qab haus huv thiab kev ua tau zoo.

Prelaminated panels process: Panels Preparation →Panels Clean→Melamine Impregnated Paper→ Lamination→ Reclean → Inspection→Store. Ua ntej kev lamination, peb yuav tsum xaiv cov ntoo zoo nkauj raws li panels thiab melamine impregnated ntawv, tsuas yog xaiv cov ntaub ntawv raw rau ntau lawm.

Impregnated ntawv yuav tsum muaj cov resin cov ntsiab lus yog 130 - 150%, cov ntsiab lus volatile 6 - 7%, tus txheej txheem them qib ≦ 65%. Melamine impregation ntawv yuav tsum tau nyob rau hauv zoo, thiab ntim nrog zaj duab xis kom tiv thaiv kev nqus ntawm noo noo. Nws yog qhov zoo dua rau laminate ua ntej 3 lub hlis tom qab kev tsim khoom, thiab khaws cia rau hauv lub tsev rau khoom nrog relaouse noo noo ntawm 60 + 5%, qhov ntsuas kub 20 - 25 ℃. Cov Panels nrov tshaj plaws yog Fiber Board, Particle Board thiab Plywood. Zoo Panels Yuav Tsum: 1) Ob Chav Sab Sanding, Qhov saum npoo yog du thiab ci tuab, thickness kam rau 0.2 hli. 2) Cov chaw tsav nkoj tau ruaj khov, tsis noj mov, tsis muaj roj lossis dej ua qias tuaj. 3) Cov ntsiab lus noo noo ntawm lub rooj tsavxwm yog tswj tau nyob hauv qhov ntau ntawm 6 - 10%.

Thaum lub sij hawm lamination txheej txheem, peb yuav tsum ua raws li cov lus qhia kev ua haujlwm, tswj nias ntsuas kub 140 - 190 ℃, Chav siab, nias sijhawm 25 - 50s. Nias qhov kub, qhov kub thiab nias lub sijhawm yog kev sib raug zoo thiab kev sib sau ua ke, uas tuaj yeem hloov kho raws li cov xovxwm kev hlub tiag tiag. Kub kub yog feem ntau yog kom nrawm dua cov tshuaj lom neeg ntawm Melamine Resin, qhov ua haujlwm kub tshaj plaws yog 140 - 190 ℃. Siab dua tuaj yeem pab tso tawm tom qab nias, thiab tuaj yeem ua rau lub sijhawm nias lub sijhawm, txhim kho ntau dua kev ua haujlwm ua ntej kev kho kom zoo nkauj, uas ua rau pore ntawm lub rooj tsavxwm. Tsim nyog lub siab tuaj yeem lav cov adhesion zoo ntawm cov laug cam thiab daim ntawv impregnated, uas yog cov khoom siv ua haujlwm feem ntau 2.0 Nyob rau hauv lub preminise zoo, lub siab siab yuav tsum siv rau lub zog ntev ntawm lub neej ntawm cov khoom siv, thiab nws tau txais txiaj ntsig zoo rau cov qauv sab hauv ntawm boars. Tab sis kev ua siab hnyav dhau yuav cuam tshuam cov nplaum muaj zog thiab cov khoom plig ntws ntws. Raws li cov khoom sib txawv ntawm cov vaj huam sib luag, chav ntsuas siab yuav tsum tau hloov kho los ntawm kev ua tsis tau. Lub sijhawm nias yog nyob ntawm kev kho cov kab ntawv los ntawm cov cob hauv daim ntawv impregnated thiab nias cov ntawv thiab ntsuas kub, thiab 25 - 50s yog qhov zoo tshaj plaws. Lub sij hawm yog ntev dhau lawm yuav ua rau resin kho tau ntau dhau thiab poob ywj, ua rau muaj kev sib tsoo lossis hauv cov txheej txheem hauv qab no yuav coj tawg, warping. Lub sij hawm yog luv heev, Resin Careing tsis txaus, ua cov laug cam nplaum thiab cuam tshuam rau cov khoom siv durability.

Kev tsom xam ntawm cov khoom tsis xws luag thiab ua rau cov panels prelaminated:

1) Cov chaw dawb, lub ntsiab yog vim li cas yog qhov tsis zoo ntawm cov ntawv luam tawm lossis cov ntsiab lus tsawg dua. Cov laj thawj yuav yog: tsis muaj sanding ntawm board saum npoo av lossis sensabe kev nyuaj siab, thiab lub siab tsis zoo ntawm cov chaw uas tsis zoo, thiab ua rau cov tshuaj tsis zoo, thiab ua rau cov khoom tsis zoo, thiab ua rau cov khoom tsis zoo, thiab ua rau cov pa tsis zoo Kev puas tsuaj, coj mus rau qhov kub sib txawv ntawm cov ntawv sib txawv ntawm cov hlau sib txawv, lossis qis dua tus nqi ntawm cov laug cam, yuav cuam tshuam rau lub rooj zaum uas muaj sia nyob thiab ua rau pom kev dawb. Cov ntaub ntawv siab dhau ntawm Melamine impration yuav coj npuas thaum lub sij hawm Lamination thiab ua rau dawb.

2) Cov chaw ntub dej, yog hais txog cov nthwv dej yoj ntawm cov ntawv sau ntub dej thaum lub sij hawm impregnated lub sij hawm, yooj yim rau cov ntsiab lus ntub dej los yog cov ntsiab lus tsis zoo ntawm cov chaw ntub dej thaum lamination.

3) Cov nplaum nrog cov phaj steel yog hais txog melamine board lo nrog hlau phaj thaum lub sij hawm Lamination. Me ntsis nplaum yuav cuam tshuam rau qhov chaw zoo, ua kom zoo nkauj yuav cuam tshuam ntau lawm.Thaum cov laj thawj yog: siab cov ntsiab lus muaj kuab paug lossis ua qias neeg. Cov ntawv hloov kho siab ntawm daim ntawv impregnated, qis nias kub thiab luv nias lub sijhawm, ua rau cov txhab nyiaj tsis tau kho kom tsis zoo. Kev puas tsuaj ntawm mat tshwm sim hauv tsis muaj qhov kub thiab txias rau ntawm cov phaj steel coj tsis zoo tso. Cov neeg noo noo cov ntsiab lus los yog cov nqi siab rau ntawm cov laug cam coj kev tso tsis zoo.

4) npuas, cov laj thawj tseem ceeb: dhau kev nias kub, ntev dhau kev nias lub sijhawm nqa Demix lossis npuas. Heev noo noo los yog nyias nyias ntawm cov laug cam yuav ua cov demix lossis npuas thaum lamination.too qis ntom ntom nyob rau hauv demix lossis npuas.

5) hneev hneev nti yog hais txog saum npoo tsis ncaj los yog txiav dabtsi yog vim muaj kev tsis zoo ntawm sab hauv lub tswv yim muaj zog. Cov laj thawj tseem ceeb yog: loj sib txawv hauv nias qhov kub thiab txias ntawm cov phaj sab saud thiab qis dua ua rau kho qhov sib txawv kho thiab ua rau hneev nti sib txawv. Txawv Melamine impregation ntawv ntawm ob qho chaw yuav ua rau khoov tom qab lamination.Ic pallots mus rau un - ca pallets, nws yuav ua rau khoov.

Hauv ntej, peb yuav tsum xaiv cov ntawv luam tawm zoo heev li cov khoom siv cov khoom lag luam sib xyaw ua ke
