Angazi ukuthi yaqala nini, i-formaldehyde ne-leukemia zivame ukuvela emehlweni ethu, futhi azikude nempilo yethu.Kungenzeka basedolobheni elilodwa, noma basemphakathini owodwa.
Ebusweni be-formaldehyde yasendlini eyeqa izinga, wonke umuntu wabonisa amakhono akhe ngempela.Abanye baye babonisa amakhono amangalisayo kule ndawo, kusukela ekutshaleni izimbali, ezifana nezimbotshana, isitshalo sesicabucabu, inhlaba... ukuphenduka ama-flower fairies.Abanye futhi bakholelwa ngokuqinile ukuthi abantu banamuhla kufanele basebenzise ubuchwepheshe obuphezulu, ngakho-ke imishini ye-ion engalungile nemishini ye-adsorption ye-formaldehyde ihanjiswe ekhaya, futhi ifenisha nomshini kuyimpahla evamile.Futhi ngemva kwesikhashana, ingabe lezi zingaxazululeka ngempela?Akudingekile ukusho, lezi zinyathelo zonke ziyi-palliative, hhayi imbangela eyinhloko.
Kodwa-ke ngakhangwa igagasi lolwazi mayelana namaphaneli angu-zero-formaldehyde.Iyini iphaneli ye-zero-formaldehyde?Ingabe inempilo ngempela?
Amaphaneli angenayo i-formaldehyde ngokuvamile abhekisela kumaphaneli angenayo i-formaldehyde engeziwe ngesikhathi sokukhiqiza nokucubungula.Sidinga ukuhlukanisa phakathi kokwengezwa kwe-zero formaldehyde kanye nokukhululwa kwe-zero formaldehyde.Ngenxa yokuthi izinkuni ngokwazo ziqukethe i-formaldehyde, akunakwenzeka ukufeza ukukhululwa kwe-zero formaldehyde.
I-interlacing ifana nentaba.Eqinisweni, ukwesaba okukhulu kubangelwa ukungazi kwethu amaqiniso.Uma sikuqonda kahle, sithola ukuthi empeleni akubi ngendlela ebesikucabanga ngayo.Into esabekayo ukuthi abanye abathengisi bazokweqisa imizwelo enjalo "yokwesaba" ukudida abathengi.
Isaziso:
Ukuba khona kwe-formaldehyde ebhodini ikakhulukazi kuvela kulezi zici ezimbili ezilandelayo:
1. Ivela empahleni eluhlaza ngokwayo.Ukhuni luqukethe inani elincane le-formaldehyde yemvelo, kodwa lincane kangangokuthi alinawo nhlobo umthelela emzimbeni womuntu.Umoya esiwuphefumulayo, ubhiya esiwuphuzayo, njll. konke kunesilinganiso esithile se-formaldehyde, futhi izinkuni ngokwazo I-Formaldehyde ayinalutho nhlobo.
Okwesibili, livela ku-glue esetshenziswa inqubo yokukhiqiza ibhodi.Kungakhathaliseki ukuthi i-wheelless i-rotary-cut veneer noma ukhuni olulayiniwe, iglue iyadingeka ukuze kuhlanganiswe nokubopha ukuze kuzuzwe ukuqina kwebhodi.Kodwa-ke, amabhodi angama-99% avela emakethe asebenzisa iglue ye-urea-formaldehyde equkethe i-formaldehyde ekukhiqizeni.Ngakho-ke, i-glue iyisihluthulelo sokulawula inani le-formaldehyde ekhishwayo.
Ibhodi eliqediwe lizoba nezixhumanisi eziningi ezifihliwe, njenge-putty, i-veneer pasting concealer, uma iqukethe i-formaldehyde, izophinde ithinte ukukhishwa kwe-formaldehyde jikelele kwebhodi.
Amanye amaphaneli okungenisa nokuthekelisa, ngenxa yokuthi adinga ukuthengiswa emhlabeni wonke, abhekisela ngokuqondile ezingeni eliqinile kakhulu - ukukhishwa kwe-formaldehyde kungaphansi kuka-0.3mg/L, futhi kusenenani elincane le-formaldehyde, ngakho-ke akukho "zero" yangempela. formaldehyde" nhlobo..
Njengoba lingekho ibhodi eline-zero formaldehyde emission, ingabe siyakhathazeka ngokuthi ukusebenzisa amabhodi okuhlobisa nakanjani kuzolimaza impilo yethu?
cha.Ukufingqa, singaqonda ukuthi izinto ezingavuthiwe zebhodi ziwukhuni, futhi ukhuni luqukethe i-trace formaldehyde, njenge-trace formaldehyde equkethwe kuma-apula, ubhiya, kanye nomzimba womuntu.Ngakho-ke, ibhodi eliqediwe lizoba ngaphezulu noma ngaphansi kwe-formaldehyde, kodwa empeleni inani elincane le-formaldehyde ngeke libe yingozi emzimbeni womuntu.Ingashintshwa ngokushesha ibe yi-"formaldehyde" emzimbeni futhi ikhishwe ngezinhlelo zokuphefumula nezomchamo.Ngakho-ke, usengasebenzisa amaphaneli womhlobiso wefenisha ngokuzethemba, kodwa udinga ukukhetha ngokucophelela lapho uthenga amaphaneli, futhi unake ukuthi izinga lamapaneli kanye nenani le-formaldehyde elikhishwe lihlangabezana nezindinganiso zikazwelonke.
Ngakho sikhetha kanjani ibhodi?Yiziphi izindinganiso zikazwelonke?
Emakethe yephaneli yasekhaya, kukhona i-E0, i-E1, ne-E2 eveza inani lokukhishwa kwe-formaldehyde.Ngomhla ziyi-10 kuZibandlela, 2001, Ukuphathwa Okujwayelekile Kokuqondisa Kwekhwalithi, Ukuhlolwa Nokuhlukaniswa Kwezinto Ze-People's Republic of China kwakhipha "Imikhawulo Yokukhishwa Kwe-Formaldehyde Kumaphaneli Asekelwe Ngokhuni Nemikhiqizo Yawo Yezinto Zomhlobiso Wangaphakathi"
(GB18580——2001), imakwe ngezinga likazwelonke elingu-E2 ≤ 5.0mg/L, i-E1 ejwayelekile kazwelonke ≤ 1.5mg/L amazinga amabili anomkhawulo, kubekwe ukuthi imikhiqizo enezinga likazwelonke elingu-E1 ingasetshenziswa ngokuqondile endlini, kanye nemikhiqizo enendinganiso kazwelonke. I-E2 kumele ihlotshiswe Ingasetshenziswa endlini kuphela ngemva kokwelashwa.Ngo-2004, ezingeni likazwelonke elithi "Plywood" (GB/T9846.1-9846.8-2004), izinga lomkhawulo lika-E0≤0.5mg/L nalo limakiwe.Izinga le-E0 elijwayelekile likazwelonke liwumkhawulo wokukhishwa kwe-formaldehyde kumaphaneli ezwe lami asekelwe ngokhuni kanye nemikhiqizo yawo.izinga eliphezulu kakhulu.
Kodwa lesi sitatimende singashintsha esikhathini esizayo.Kusukela ngoMeyi 1 kulo nyaka, njengokuwukuphela kwendinganiso eyisibopho embonini, i-GB18580-2017 "Imikhawulo Yokukhishwa Kwe-Formaldehyde Kumaphaneli Asekelwe Ngokhuni Nemikhiqizo Yawo Yezinto Zokuhlobisa Ngaphakathi" yaqala ukusebenza.Enguqulweni entsha yezinga, izimfuneko zomkhawulo zokukhululwa kwe-formaldehyde ziyakhuphuka, inani elilinganiselwe lokukhululwa kwe-formaldehyde libalulwe njengo-0.124 mg/m3, umaki womkhawulo ngu-"E1", kanye nezinga elithi "E2" lezinga lokuqala lingu-0.124 mg/m3. kukhanseliwe;futhi indlela yokuhlola yokuthola i-formaldehyde ihlanganiswe "njenge-1m3 chamber Law chamber".
Leli zinga liyisisekelo sokuhlola ukuthi ukukhishwa kwe-formaldehyde kwemikhiqizo kuyafaneleka yini, okusho ukuthi ukukhishwa kwe-formaldehyde kuyo yonke imikhiqizo yokhuni kufanele kuhlangabezane nezidingo zaleli zinga.
Uma ibhizinisi likhiqiza imikhiqizo eqinile kunezinga elisha elithi "E1" (≤0.124 mg/m3) futhi lihlangabezana nezimfuneko ze-GB/T 35601-2017 "Ukuhlolwa Komkhiqizo Oluhlaza Wamaphaneli Asekelwe Ngokhuni Nezitezi Zokhuni", bangakhetha ukusebenzisa indinganiso kazwelonke ye-GB /T 35601-2017.I-GB/T 35601-2017 izosetshenziswa ngoJulayi 1, 2018. Inani lenkomba yomkhawulo walo we-formaldehyde lingaphansi noma lilingana no-0.05 mg/m3, futhi indlela yokuthola iyafana ne-GB 18580-2017.Ngaleso sikhathi, izinga eliphakeme kakhulu elimele umkhawulo wokukhishwa kwe-formaldehyde kumaphaneli asekhaya lizoba phezulu kakhulu.
Ukufingqa, uphawu "E2" luzophuma kancane kancane emakethe.Lapho abathengi bethenga izinto zokwakha, uma umthengisi ethi "E2" ingumkhiqizo ofanelekayo, kufanele baqaphe futhi bangathengi imikhiqizo engahlangabezani nezindinganiso zikazwelonke.Abathengi bayelulekwa ukuthi bathenge amabhodi afinyelele izinga le-E0.Uma bethenga imikhiqizo esanda kufinyelela ezingeni elijwayelekile (izinga le-E1), ngemva kokuqedwa kokuhlobisa, kunconywa ukuvula amafasitela isikhathi sokuphefumula ngaphambi kokungena, okungcono ngaphezu kwezinyanga ezintathu.
I-Dongguan MUMU Woodworking Co., Ltd. ingumkhiqizi nomphakeli wezinto zokwakha zaseShayina ezimunca umsindo.Sicela usithinte ukuze uthole ulwazi olwengeziwe!
