Txhawm rau txiav txim siab seb cov vaj huam sib luag honeycomb puas siv formaldehyde-dawb nplaum, cov ntsiab lus tseem ceeb yog: Nrhiav cov ntawv pov thawj kev soj ntsuam, ua tib zoo saib xyuas cov ntsiab lus ntawm cov khoom, thiab saib xyuas cov khoom lag luam muaj txiaj ntsig zoo. Cia kuv muab nws tso rau koj:
Lub hauv paus txhim khu kev qha tshaj plaws: Tshawb xyuas cov ntawv pov thawj kev xeem ntawv pov thawj. Thov ncaj qha rau tus neeg muag khoom kom muab daim ntawv tshaj tawm tsis ntev los no formaldehyde emission test (xws li CMA ntawv pov thawj). Qhov no yog lub hom phiaj nkaus xwb. Ua tib zoo mloog rau:
Cov qauv ntsuas: Nws puas ua tau raws li qib ENF (tsawg dua lossis sib npaug ntawm 0.025mg / m³) lossis E0 qib (tsawg dua lossis sib npaug rau 0.050mg / m³)? Qhov no yog tus qauv kub rau cov tsev noj qab haus huv.
Kev sim cov txheej txheem: Xws li "desiccant method" lossis "climate chamber method," thiab cov txiaj ntsig yuav tsum tau sau meej meej nrog cov lej muaj nuj nqis.
Saib xyuas cov ntsiab lus ntawm cov khoom thiab kev ua haujlwm.
Tsis hnov tsw: Cov vaj huam sib luag tshiab tsis muaj ntxhiab tsw ntxhiab (cov nplaum tsis zoo yuav muaj ntxhiab tsw ntxhiab).
Tshawb xyuas Cov Txheej Txheem Nto thiab Rov Qab: Siab- cov vaj huam sib luag zoo siv txheej txheem txheej txheej, ua kom muaj kev sib raug zoo ntawm cov txheej txheej thiab cov khoom siv txhuas. Cov txheej txheem rov qab siv cov khoom siv los tiv thaiv- xeb, lav tsis muaj xeb rau ntau tshaj 20 xyoo.
Tshawb xyuas Honeycomb Core: Tear qhib ib qho qauv thiab saib seb cov nplaum nplaum puas zoo ib yam thiab tsim nyog. Cov nplaum nplaum ntau dhau tuaj yeem qhia tias tsis muaj ib puag ncig tus phooj ywg.
Xaiv Lub Hom Phiaj thiab nkag siab txog txheej txheem:
Muab qhov tseem ceeb tshaj -paub hom. Lawv cov kev tswj kom zoo thiab cov qauv ib puag ncig muaj kev ntseeg siab dua. Lawv feem ntau siv polyurethane ib puag ncig tus phooj ywg adhesives, uas tsis yog - lom, tsis muaj ntxhiab, thiab muaj zog tsis kam mus rau qhov kub thiab txias.
Nkag siab hom Adhesive: Formaldehyde- cov nplaum dawb feem ntau xa mus rau polyurethane adhesives lossis MDI eco-adhesives. Txawm li cas los xij, nco ntsoov tias MDI cov nplaum tuaj yeem tso tawm me me ntawm xylene thiab muaj cov dej tsis zoo.
Kev txiav txim ceev thiab ceev faj:
Ceev faj ntawm qhov hype nyob ib puag ncig "formaldehyde-dawb" lub tswv yim: Honeycomb panels lawv tus kheej siv cov nplaum me me, thiab cov formaldehyde tso tawm feem ntau tsis muaj teeb meem ntawm txhua tus nqi taw tes. Tus nqi siab yog rau "formaldehyde-dawb" daim ntawv lo.
Tsom ntsoov rau qhov sib npaug ntawm kev tiv thaiv ib puag ncig thiab kav ntev: Cov Boards ua nrog polyurethane ib puag ncig tus phooj ywg adhesives muaj nplaum lub zog thiab durability uas tuaj yeem tiv taus qhov hnyav ib puag ncig.
