Melamine Ipregnation

Melamine impregation ntawv, siv cov ntawv sau zoo nkauj dai kom zoo nkauj, impregnated nrog melamine cob, ces laminated rau txhua yam ntoo raws Panels. Nws ua tau zoo nkauj zoo nkauj zoo nkauj rau saum npoo av, thiab ua kom lub ntsej muag tiv taus qhov kub, hnav thiab anti muaj kuab paug.

Ntawm tam sim no tus impregnation feem ntau yog adopts ob zaug saturation. Lub dai daim ntawv yog xub impregnated nrog kev cob qhia li qub kom tau txais cov txheej txheem me me, tom qab ntawd Melamine Resin tuaj yeem kho tau qhov tseeb ntawm melamine impregnated daim ntawv, thiab ua kom muaj kev lag luam lag luam. Impregnation muaj cov cai nruj rau cov ntawv dai thiab melamine cob. Lub resin tom qab kev ntsuas yuav tsum tau txais qhov yooj, uas tuaj yeem tiv thaiv lub sab nrib pleb. Hauv kev tsim khoom, melamine me me tseem yuav tsum tau ntxiv ntau yam ntxiv.

Txhawm rau lav qhov zoo ntawm melamine impregnated ntawv, zoo hniav zoo nkauj yuav tsum tau siv. Cov ntawv dai kom zoo nkauj tsis muaj fiber ntau, ua tau zoo nyob rau hauv cov xim rho tawm, thiab tiv taus cov kub ntawm 180 c, thiab ntawm zoo opacity. Nyob rau hauv ib txwm muaj grammage ntawm decor ntawv yuav tsum yog 70-90g / ㎡, cov ntsiab lus noo noo 2.5 - Phaj 6.5 - 7.5. Yog tias tus nqi PH yog tsawg dhau, nws yuav ua pa hluav taws xob thaum lub sij hawm impregnation. Txhawm rau kom tsis txhob tawg thaum Impregnation, qhov ntev ntawm lub sijhawm ntub dej ntev yog tsawg kawg yog 450m, thiab tom qab 300m. Txhawm rau kom tau txais kev zoo impregnation ceev, kho kom zoo nkauj yuav tsum muaj siab heev nrog kev nkag sai sai. Dej Xuas Qhov Yuav Tsum Tau Ua: Ntsug 25 - 35 hli / min, Kab rov tav 22 - 30mm / min. Smoocks ntawm cov ntaub ntawv kho kom zoo yuav tsum muaj qhov tsawg, qis dhau tej zaum yuav cuam tshuam cov lamination nyhuv rau saum npoo thiab siab dhau yuav txo cov peev xwm ntawm kev siv hluav taws xob impregnating.

Cov khoom siv los yog MED MF thiab UF, nrog rau ntau yam ntxiv. Kev kho cov ntxiv ua si lub luag haujlwm ntawm catalyst mus ua kom nrawm khu lub sijhawm kho thaum lamination. Kev ntub dej muaj ntxiv yog txhawm rau kom txo cov nro, thiab txhim kho lub peev xwm tob rau ntawm daim ntawv dai kom paub meej tias kev sib dhos impregnation. Kev tso tawm yog siv los tiv thaiv cov ntawv impregnated los ntawm steel phaj thaum siv kom tsis txhob muaj npuas hauv cov dej da dej uas yuav cuam tshuam kev sib txuam impregnating. Cov kuab tshuaj yog dej lossis ethanol, diluted kom kho lub viscosity kom tau txais zoo permeability ntawm cov ntawv kho kom zoo nkauj. Siv cov kua nplaum tshwj xeeb thev naus laus zis ua kom muaj zog ntxiv, tso tawm ntxiv, ua npuas dej ntxiv, ua npuas dej ntxiv thiab lwm yam ntxiv, txhaj rau hauv da dej. Tom qab ob zaug impregnation, cov ntawv kho kom zoo nkauj yuav tsum tau qhuav, txias thiab txiav rau qee qhov ntau thiab tsawg. Qhov loj me yuav tsum tau txog 10 - 30mm loj dua panels nyob rau hauv qhov dav thiab ntev. Nrog kev pom zoo, cov ntawv tiav melamine tiav melamine impregnated daim ntawv tuaj yeem ntim tau los ntawm polyethylene zaj duab xis. Txog 200 nplooj ntawv ib bale, 10 bales txhua pallet. Txhawm rau kom ntseeg tau zoo li lamination, melamine impregnated ntawv yuav tsum muab cia rau hauv cov xwm txheej zoo. Cov txheeb ze cov av noo nyob rau hauv lub tsev rau khoom yog 60 ± 5%, yog li ntawd daim ntawv yuav tsis nqus lossis tso dej noo. Qhov kub yuav tsum yog 20 - 25 ℃. Kev kub siab thiab cov av noo ua rau cov ntawv luam tawm ua kom tawv nqaij ua mos thiab nplaum. Tab sis impregnated daim ntawv yog yooj yim tawg thaum qhov ntsuas kub tsawg dhau. Lub txee lub neej ntawm daim ntawv impregnated yog li 3 lub hlis yog tias lawv khaws cia zoo. Txhawm rau tiv thaiv cov nplaum vim tias kev nqus dej noo, thov rov ua dua tshiab thiab muab tso cia thiab muab pov tseg zoo ib zaug qhib.

Cov txheej txheem cob qhia (cov khoom tsim khoom sib txheeb ze rau qhov hnyav ntawm lub cob) yog 130 - 150%. Cov ntsiab lus qis cov ntsiab lus nqa lub zog tsawg ntawm daim ntawv, thiab nws yooj yim rau Dimx. Cov ntsiab lus zoo melamine kom zoo yog qhov zoo rau kev lamination nyob rau hauv ntau lawm thiab zoo. Thaum cov resin cov ntsiab lus dhau lawm, nws yooj yim rau tawg. Cov ntsiab lus ntawm kev hloov pauv (ntawm 160 ℃ Kom qhuav li 10 feeb) yog 6 - 7%.
