Kodi masamba a zero formaldehyde alipodi?

 

 

 

 

Koma kenako ndinakopeka ndi chidziwitso chambiri chokhudza mapanelo a zero-formaldehyde.Kodi gulu la zero-formaldehyde ndi chiyani?Kodi ndi wathanzi?

Mapanelo opanda formaldehyde nthawi zambiri amatanthauza mapanelo opanda formaldehyde omwe amawonjezeredwa panthawi yopanga ndi kukonza.Tiyenera kusiyanitsa pakati pa zero formaldehyde kuwonjezera ndi zero formaldehyde kumasulidwa.Chifukwa matabwawo ali ndi formaldehyde, ndizosatheka kutulutsa zero formaldehyde.

Kulowerana kuli ngati phiri.Ndipotu, mantha ambiri amabwera chifukwa cha kusadziwa kwathu zenizeni.Tikamvetsetsa bwino, timapeza kuti sizowopsa monga momwe timaganizira.Chochititsa mantha ndi chakuti amalonda ena amakokomeza "mantha" oterowo kuti asokoneze ogula.

Kukhalapo kwa formaldehyde mu bolodi makamaka kumachokera kuzinthu ziwiri izi:

1. Zimachokera ku zopangira zokha.Wood imakhala ndi kachulukidwe kakang'ono ka formaldehyde, koma ndi yaying'ono kwambiri kotero kuti ilibe mphamvu pathupi la munthu.Mpweya umene timapuma, mowa umene timamwa, ndi zina zotero, zonse zimakhala ndi kuchuluka kwa formaldehyde, ndipo nkhuni zomwe Formaldehyde zimasowa.

Chachiwiri, zimachokera ku guluu wogwiritsidwa ntchito popanga bolodi.Kaya chopanda magudumu ndi chozungulira chozungulira kapena matabwa opangidwa ndi laminated, guluu ndi lofunika polumikizana ndi kumangiriza kuti bolodi likhale lolimba.Komabe, 99% ya matabwa omwe amawonekera pamsika amagwiritsa ntchito guluu wa urea-formaldehyde wokhala ndi formaldehyde popanga.Chifukwa chake, guluu ndiye chinsinsi chowongolera kuchuluka kwa formaldehyde yotulutsidwa.

Bolodi yomalizidwa idzakhala ndi maulalo obisika ambiri, monga putty, veneer pasting concealer, ngati ili ndi formaldehyde, ikhudzanso kutulutsa kwa formaldehyde konsekonse.

Mapanelo ena olowetsa ndi kutumiza kunja, chifukwa amafunika kugulitsidwa padziko lonse lapansi, amatchula mwachindunji muyezo wovuta kwambiri - kutulutsa kwa formaldehyde kumakhala kochepera 0.3mg/L, ndipo pamakhalabe formaldehyde pang'ono, kotero palibe "zero" yeniyeni. formaldehyde" konse..

Popeza kulibe bolodi yokhala ndi zero formaldehyde emission, kodi timada nkhawa kuti kugwiritsa ntchito matabwa kukongoletsa kuwononga thanzi lathu?

ayi.Pomaliza, titha kumvetsetsa kuti zida za bolodi ndi nkhuni, ndipo matabwa amakhala ndi trace formaldehyde, monga trace formaldehyde yomwe ili mu maapulo, mowa, ndi thupi la munthu.Chifukwa chake, bolodi yomalizidwayo imakhala ndi formaldehyde, koma kwenikweni formaldehyde yaying'ono sikhala yovulaza thupi la munthu.Itha kusinthidwa mwachangu kukhala "formaldehyde" m'thupi ndikutulutsidwa kudzera m'mitsempha ya kupuma ndi mkodzo.Choncho, mukhoza kugwiritsa ntchito mapanelo kwa mipando zokongoletsera ndi chidaliro, koma muyenera kusankha mosamala pogula mapanelo, ndi kulabadira ngati khalidwe mapanelo ndi kuchuluka kwa formaldehyde anamasulidwa kukumana mfundo dziko.

Ndiye timasankha bwanji bolodi?Mfundo za dziko ndi zotani?

Pamsika wapakhomo, pali E0, E1, ndi E2 zomwe zimawonetsa kuchuluka kwa utsi wa formaldehyde.Pa Disembala 10, 2001, General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China idapereka "Malire a Formaldehyde Release mu Wood-based Panel ndi Zawo Zopangira Zokongoletsera Mkati"

(GB18580——2001), yolembedwa ndi E2 ya dziko ≤ 5.0mg/L, E1 yadziko lonse ≤ 1.5mg/L milingo iwiri yocheperako, ikuti mankhwala okhala ndi E1 amtundu wa E1 atha kugwiritsidwa ntchito mwachindunji mnyumba, ndi zinthu zomwe zili ndi muyezo wadziko lonse. E2 iyenera kukongoletsedwa Itha kugwiritsidwa ntchito m'nyumba pokhapokha mutalandira chithandizo.Mu 2004, mu muyezo wadziko lonse "Plywood" (GB/T9846.1-9846.8-2004), malire a E0≤0.5mg/L adalembedwanso.Mulingo wa E0 wadziko lonse ndi malire a kutulutsidwa kwa formaldehyde mu mapanelo opangidwa ndi matabwa a dziko langa ndi zinthu zawo.muyezo wapamwamba kwambiri.

Koma mawu amenewa akhoza kusintha m’tsogolo.Kuyambira pa Meyi 1 chaka chino, monga muyezo wokhawo wovomerezeka pamakampaniwo, GB18580-2017 "Malire a Formaldehyde Kutulutsidwa mu Ma Panel Opangidwa ndi Wood ndi Zopangira Zawo Zokongoletsera Zamkati" zidayamba kugwira ntchito.Mu mtundu watsopano wa muyezo, malire omwe amafunikira kuti atulutse formaldehyde akuchulukidwa, malire a kutulutsidwa kwa formaldehyde amanenedwa kukhala 0.124 mg/m3, malire ndi "E1", ndipo mulingo wa "E2" wa muyezo woyambirira ndi. kuthetsedwa;ndipo njira yoyesera yodziwira formaldehyde imalumikizidwa ngati "1m3 chamber chamber Law".

Mulingo uwu ndiye maziko oyesa ngati kutulutsa kwa formaldehyde kwazinthu ndikoyenera, zomwe zikutanthauza kuti kutulutsa kwa formaldehyde pazinthu zonse zamatabwa kuyenera kukwaniritsa zofunikira za mulingo uwu.

Ngati kampaniyo ikupanga zinthu zokhwima kwambiri kuposa mulingo watsopano wa "E1" (≤0.124 mg/m3) ndikukwaniritsa zofunikira za GB/T 35601-2017 "Green Product Evaluation of Wood-based Panels and Wooden Floors", angasankhe kugwiritsa ntchito muyezo wadziko lonse wa GB /T 35601-2017.GB/T 35601-2017 idzagwiritsidwa ntchito pa July 1, 2018. Mndandanda wake wa malire a formaldehyde ndi wocheperapo kapena wofanana ndi 0.05 mg / m3, ndipo njira yodziwira ndi yofanana ndi GB 18580-2017.Panthawiyo, mulingo wapamwamba kwambiri womwe umayimira malire a formaldehyde kuchokera ku mapanelo am'nyumba udzakhala wapamwamba kwambiri.

Pomaliza, chizindikiro cha "E2" chidzachoka pamsika pang'onopang'ono.Ogula akagula zinthu zomangira, ngati wamalonda akunena kuti "E2" ndi chinthu choyenera, ayenera kukhala tcheru ndipo asagule zinthu zomwe sizikugwirizana ndi dziko.Ogula akulangizidwa kuti agule matabwa omwe afika pa mlingo wa E0.Ngati agula zinthu zomwe zangofika pamlingo (E1 level), zokongoletsa zikamalizidwa, tikulimbikitsidwa kuti mutsegule mawindo kwa nthawi yopumira musanayambe kusuntha, makamaka kuposa miyezi itatu.

Dongguan MUMU Woodworking Co., Ltd. ndi kampani yaku China yopanga ndi kugulitsa zida zomangira zomwe zimakomera mawu.Chonde titumizireni kuti mudziwe zambiri!
