Andazi ukuba yaqala nini, iformaldehyde neleukemia zisoloko zibonakala emehlweni ethu, yaye azikude kubomi bethu.Basenokuba bakwisixeko esinye, okanye bakwindawo enye.
Ebusweni be-formaldehyde yangaphakathi edlula umgangatho, wonke umntu wabonisa iitalente zabo.Abanye babonise izakhono ezigqwesileyo kule ndawo, ukuqala ukutyala iintyatyambo, ezifana nemingxuma, isityalo sesigcawu, ikhala...Abanye bakholelwa ngokuqinisekileyo ukuba abantu banamhlanje kufuneka babambe itekhnoloji ephezulu, ke izixhobo ze-ion ezingalunganga kunye nezixhobo ze-adsorption ze-formaldehyde ziye zafuduselwa ekhaya, kunye nefenitshala kunye nomatshini zizixhobo eziqhelekileyo.Yaye emva kwethuba, ngaba ngokwenene ezi zinto zinokuconjululwa?Ngokungathandabuzekiyo, la manyathelo onke azizithomalalisi, hayi oyena nobangela.
Kodwa ke ndatsalwa lulwazi oluninzi malunga neepaneli ze-zero-formaldehyde.Yintoni iphaneli engu-zero-formaldehyde?Ngaba isempilweni ngokwenene?
Iiphaneli ezingenayo i-formaldehyde zihlala zibhekisa kwiipaneli ezingenayo i-formaldehyde eyongeziweyo ngexesha lokuvelisa kunye nokucubungula.Kufuneka sahlule phakathi kodibaniso lwe-zero formaldehyde kunye nokukhululwa kwe-zero formaldehyde.Ngenxa yokuba ukhuni ngokwalo luqukethe i-formaldehyde, akunakwenzeka ukufezekisa ukukhululwa kwe-zero formaldehyde.
I-interlacing ifana nentaba.Enyanisweni, uloyiko oluninzi luvela ekungazini kwethu izibakala.Xa siyiqonda ngokucokisekileyo, sifumanisa ukuba eneneni ayiyoyiki njengoko besicinga.Into eyoyikisayo kukuba abanye abathengisi baya kuzibaxa iimvakalelo ezinjalo "zoloyiko" ukuze badideke abathengi.
Isaziso:
Ubukho be-formaldehyde ebhodini ikakhulu buvela kule miba mibini ilandelayo:
1. Iphuma kwimathiriyeli ekrwada ngokwayo.Ukhuni luqukethe inani elincinci le-formaldehyde yendalo, kodwa incinci kangangokuba ayinayo impembelelo kumzimba womntu konke konke.Umoya esiwuphefumlayo, ibhiya esiyiselayo, njl.njl zonke zinenani elithile le-formaldehyde, kwaye ukhuni ngokwalo i-Formaldehyde ayinanto kwaphela.
Okwesibini, ivela kwiglue esetyenziswe kwinkqubo yokuvelisa ibhodi.Ingaba i-wheelless yi-rotary-cut veneer okanye i-laminated wood, iglue iyafuneka ukuze udibanise kunye nokudibanisa ukufezekisa ukuqina kwebhodi.Nangona kunjalo, i-99% yeebhodi ezibonakala kwiimarike zisebenzisa i-urea-formaldehyde glue equkethe i-formaldehyde kwinkqubo yokuvelisa.Ke ngoko, iglu isitshixo sokulawula ubungakanani be-formaldehyde ekhutshwayo.
Ibhodi egqityiweyo iya kuba neekhonkco ezininzi ezifihliweyo, ezifana ne-putty, i-veneer pasting concealer, ukuba iqulethe i-formaldehyde, iya kuchaphazela ukukhutshwa kwebhodi yonke ye-formaldehyde.
Ezinye iipaneli zokungenisa kunye nokuthumela ngaphandle, kuba kufuneka zithengiswe kwihlabathi jikelele, zibhekisela ngokuthe ngqo kumgangatho onzima kakhulu - ukukhutshwa kwe-formaldehyde kungaphantsi kwe-0.3mg / L, kwaye kusekho inani elincinci le-formaldehyde, ngoko akukho "zero" yangempela. formaldehyde" ngokupheleleyo..
Ekubeni kungekho bhodi ene-zero formaldehyde emission, ngaba sinexhala lokuba ukusebenzisa iibhodi zokuhombisa ngokuqinisekileyo kuya kuyonakalisa impilo yethu?
Hayi.Ukushwankathela, sinokuqonda ukuba izinto eziluhlaza zebhodi zikhuni, kwaye iinkuni ziqulethe i-trace formaldehyde, njenge-trace formaldehyde equlethwe kwiiapile, ibhiya kunye nomzimba womntu.Ngoko ke, ibhodi egqityiweyo iya kuba ngaphezulu okanye ngaphantsi kwe-formaldehyde, kodwa ngokwenene i-formaldehyde encinci ayiyi kuba yingozi kumzimba womntu.Inokuthi ifakwe ngokukhawuleza kwi-metabolized ibe "formaldehyde" emzimbeni kwaye ikhutshwe ngeendlela zokuphefumla kunye nomchamo.Ngoko ke, usenokusebenzisa iipaneli zokuhombisa ifenitshala ngokuzithemba, kodwa kufuneka ukhethe ngokucophelela xa kuthengwa iipaneli, kwaye ubeke ingqalelo ukuba umgangatho weepaneli kunye nesixa se-formaldehyde ekhutshweyo ihlangabezana nemigangatho yelizwe.
Ngoko sikhetha njani ibhodi?Yeyiphi imigangatho yesizwe?
Kwimarike yephaneli yasekhaya, kukho i-E0, i-E1, kunye ne-E2 ebonisa inani lokukhutshwa kwe-formaldehyde.Ngomhla we-10 kaDisemba, i-2001, i-General Administration of Quality Supervision, ukuhlolwa kunye ne-Quarantine yeRiphabhlikhi yaBantu baseChina yakhupha "iMida yokuKhupha i-Formaldehyde kwiiPaneli ezisekelwe kwi-Wood kunye neeMveliso zazo zeMpahla zokuhombisa zangaphakathi"
(GB18580——2001), ephawulwe ngomgangatho wesizwe E2 ≤ 5.0mg/L, umgangatho wesizwe E1 ≤ 1.5mg/L amanqanaba amabini aqingqiweyo, kumiselwe ukuba iimveliso ezinomgangatho wesizwe we-E1 zinokusetyenziswa ngokuthe ngqo ngaphakathi, kunye neemveliso ezinomgangatho wesizwe. I-E2 kufuneka ihlotshiswe Inokusetyenziswa ngaphakathi kwindlu kuphela emva kokuba unyango.Ngo-2004, kumgangatho kazwelonke "Plywood" (GB/T9846.1-9846.8-2004), inqanaba lomda we-E0≤0.5mg/L laphawulwa.Inqanaba lesizwe le-E0 ngumda wokukhululwa kwe-formaldehyde kwiipaneli zelizwe lam kunye nemveliso yazo.owona mgangatho uphezulu.
Kodwa le ngxelo inokutshintsha kwixesha elizayo.Ukuqala ngo-Meyi 1 kulo nyaka, njengowona mgangatho kuphela ogunyazisiweyo kwishishini, i-GB18580-2017 "Imida ye-Formaldehyde Ukukhutshwa kwiiPaneli ezisekelwe kwi-Wood kunye neMveliso yazo yeMpahla yoMhlobiso wangaphakathi" yaqala ukusebenza.Kwinguqu entsha yomgangatho, iimfuno zomda wokukhululwa kwe-formaldehyde zonyuswa, ixabiso elilinganiselwe lokukhululwa kwe-formaldehyde lichazwe njenge-0.124 mg / m3, uphawu olulinganiselwe ngu "E1", kunye nenqanaba "E2" lomgangatho wokuqala. irhoxisiwekwaye indlela yovavanyo lokubona i-formaldehyde idityaniswe njenge "1m3 yegumbi lemozulu uMthetho".
Lo mgangatho usisiseko sokuvavanya ukuba ukukhutshwa kwe-formaldehyde yeemveliso kufanelekile, oku kuthetha ukuba ukukhutshwa kwe-formaldehyde yazo zonke iimveliso zokhuni kufuneka kuhlangabezane neemfuno zalo mgangatho.
Ukuba ishishini livelisa iimveliso ezingqongqo kunomgangatho omtsha "E1" (≤0.124 mg / m3) kwaye uhlangabezana neemfuno ze-GB/T 35601-2017 "Uvavanyo lweMveliso eluhlaza yeePaneli ezisekelwe kwiMithi kunye neMigangatho yoMthi", banokukhetha ukuphumeza umgangatho wesizwe we-GB /T 35601-2017.I-GB / T 35601-2017 iya kuphunyezwa ngoJulayi 1, 2018. Ixabiso layo le-formaldehyde limit index lingaphantsi okanye lilingana ne-0.05 mg / m3, kwaye indlela yokufumanisa iyafana ne-GB 18580-2017.Ngelo xesha, umgangatho ophezulu omele umda wokukhutshwa kwe-formaldehyde kwiipaneli zasekhaya uya kuba phezulu ngakumbi.
Ukushwankathela, uphawu "E2" luya kuhoxiswa ngokuthe ngcembe kwimarike.Xa abathengi bethenga izinto zokwakha, ukuba umthengisi ubiza ukuba "i-E2" iyimveliso efanelekayo, kufuneka baqaphele kwaye bangathengi iimveliso ezingahambelani nemigangatho kazwelonke.Abathengi bayacetyiswa ukuba bathenge iibhodi ezifikelele kwinqanaba le-E0.Ukuba bathenga iimveliso ezisanda kufikelela kumgangatho (inqanaba le-E1), emva kokuba umhlobiso ugqityiwe, kucetyiswa ukuba uvule iifestile ngexesha lokungena komoya ngaphambi kokungena, ngokukhethekileyo ngaphezu kweenyanga ezintathu.
