Sida formaldehyde looga sii daayo joodariga guga

Qore: Synwin- Soo saaraha furaash

Hordhac Formaldehyde (HCHO) waa gaas cuncun leh oo aan midab lahayn. Soo-gaadhista muddada-dheer ee qiyaasta-hooseeya ee formaldehyde waxay sababi kartaa cudurrada neef-mareenka oo gaabis ah, halka formaldehyde-takoorka-sare uu sun u yahay habka dareemayaasha, habka difaaca, iyo beerka. , waxayna u horseedi kartaa kansarka sanka, afka, cunaha, maqaarka iyo habka dheefshiidka. Haddii ilmaha dhawaan dhashay uu la kulmo formaldehyde muddo dheer, waxay keeni doontaa hoos u dhac xagga jirka ah, cilladaha koromosoomyada, iyo xitaa waxay keentaa carruurta inay la ildaran yihiin cudurka leukemia. Haddii sii daynta formaldehyde ee barkin jilicsan ee guga uu buux dhaafiyay waxay si toos ah ula xiriirtaa badbaadada iyo caafimaadka isticmaalayaasha alaabada.

QB1952.2-2004 "Barkin jilicsan guga jilicsan" waxa loola jeedaa GB18587-2001 "Qalabka Qurxinta Gudaha ee Rooga, Xadhkaha rooga iyo Xabagta rooga Siideynta Tirada Siideynta Walxaha Khatarta ah" si loo codsado qadarka formaldehyde ee la sii daayay, iyo in la yareeyo qadarka ≤0.050mg/m2•h, habku waa habka qolka tijaabada yar ee deegaanka. Natiijooyinka baadhista ee sannadihii la soo dhaafay waxay muujinayaan in heerka u qalma ee sii daaya formaldehyde uu ka badan yahay 80%. Sii daynta ugu sareysa ee formaldehyde ee alaabta aan u qalmin ee Foshan furaashku waa ilaa 1.866mg/m2•h, taas oo dhaaftay shuruudaha ogolaanshaha caadiga ah in ka badan 37 jeer. Mashruucani wuxuu la xiriiraa qof walba noloshiisa iyo caafimaadkiisa, waxaana lagama maarmaan ah in la gaaro 100% shuruudaha.

Waxaa jira saddex ilood oo waaweyn oo formaldehyde ah oo joodariga ku jira: (1) Caagagga xumbo-xumada ah iyo fiber kiimikaad ee dareema ee loo isticmaalo joodariga ayaa lagu buufiyaa koollo inta lagu jiro daawaynta, koollada ayaa qani ku ah qaddar go'an oo formaldehyde ah. In kasta oo Warshadda Furashka Foshan ay hadda leedahay koollo-free formaldehyde, laakiin qiimuhu guud ahaan wuu sarreeyaa, inta badanna soo saarayaasha ma isticmaali doonaan; (2) Midabka, walxaha ka-hortagga laalaabka, walxaha-ilaalinta iyo kaaliyeyaasha kale ee lagu daro dharka gogosha ayaa qani ku ah formaldehyde, waxaana aad u fudud in wax-soo-saarayaashu ay isticmaalaan kaaliyeyaasha hodanka ah ee formaldehyde si ay u daaweeyaan dharka Way fududahay in la sameeyo formaldehyde oo ka buuxsamay dharka; (3) Buuxinta formaldehyde waxay si gaar ah halis u tahay marka timirta qumbaha ama timirta buurta loo isticmaalo gogosha. Si indho la'aan ah uga qaybqaadashada xabagyada badan, inkasta oo sifooyinka jireed ee jajabyada buniga ah la hagaajiyay, siideynta joogtada ah ee formaldehyde ee xabagta ayaa sababtay formaldehyde. Sanado badan, sharciyeeyayaasha dawladu waxay wadeen inay kordhiyaan baadhista badeecadaha oo ay ciqaabaan shirkadaha aan u qalmin. Iyadoo horumarinta joogtada ah ee wacyigelinta macaamiisha ee ilaalinta deegaanka, marka la dooranayo barkimooyinka jilicsan ee guga, waxa ugu muhiimsan waa guud ahaan shaqada ilaalinta deegaanka ee alaabta.

Sidaa darteed, haddii ay tahay dhinaca nidaamka dawladda ama baahida suuqa, waa lagama maarmaan in shirkad kastaa fiiro gaar ah u yeelato tayada ilaalinta deegaanka ee barkimooyinka jilicsan ee guga. Maqaalkan waxa soo ururisay Foshan furaash.
