Kuthatha isikhathi esingakanani ukuhlola okuqukethwe kwe-formaldehyde kuma-silicone hip pads?

Njengoba isidingo somhlaba wonke semikhiqizo enobungani nemvelo kanye nenempilo sikhula, ama-silicone hip pads, njengento evamile yasekhaya, abe yinto egxilwe kakhulu kubathengi bamazwe ngamazwe ngobuningi. Lesi sihloko sizohlola ngokuningiliziwe inqubo, isikhathi esidingekayo, kanye nezinyathelo ezifanele zokuhlola okuqukethwe kwe-formaldehyde kwama-silicone hip pads ukusiza abathengi baqonde kangcono le nqubo.

1. Isizinda sokuhlolwa kwe-formaldehyde kwama-silicone hip pads
Kusukela kuma-silicone hip padsZithambile, zihlala isikhathi eside, futhi zinobungani nemvelo, zisetshenziswa kakhulu efenisha yasekhaya, ezihlalweni zezimoto, kanye nasefenisha yehhovisi. Kodwa-ke, ngenxa yeglue noma amanye amakhemikhali angasetshenziswa enqubweni yokukhiqiza, ama-silicone hip pads angakhipha i-formaldehyde, engabangela ingozi empilweni yabantu. Ngakho-ke, ukuhlola okuqukethwe kwe-formaldehyde kwama-silicone hip pads sekuyinto ebalulekile ukuqinisekisa ukuthi umkhiqizo uhlangabezana nezindinganiso zomhlaba wonke.

2. Inqubo yokuhlola i-formaldehyde
1. Ukulungiselela isampula
Ngaphambi kokuhlola, amasampula ama-silicone hip pads adinga ukulungiswa. Amasampula kufanele akhethwe ngokungahleliwe eqenjini lokukhiqiza ukuqinisekisa ukuthi ameleleka. Amasampula adinga ukugezwa ngamanzi ahlanzekile futhi avalwe ukuze kuvinjelwe ukungcola kwangaphandle.

2. Isikhathi esivaliwe
Ukuhlolwa kwe-formaldehyde ngokuvamile kudinga ukwenziwa endaweni evaliwe. Ngokusho kwe-National Indoor Air Quality Standard (GB/T 18883-2002), iminyango namafasitela kufanele kuvalwe amahora ayi-12 ngaphambi kokuhlolwa ukuqinisekisa ukuthi imiphumela yokuhlolwa iseduze nokusetshenziswa kwangempela.
3. Ukusampula nokuhlaziya
Ukutholwa kwe-formaldehyde kuvame ukusebenzisa i-phenol reagent spectrophotometry. Izinyathelo ezithile zifaka:
Ukusampula: Sebenzisa ithubhu lokumunca ukuze uqoqe amasampula omoya, futhi isikhathi sokusampula singaba yimizuzu engama-20.
Ukuthuthukiswa kombala nokunqunywa: Buyisela amasampula aqoqwe elabhorethri ukuze kuthuthukiswe umbala kanye nokunqunywa kokumuncwa kwawo ukuze kubalwe ukuhlushwa kwe-formaldehyde.
4. Isikhathi sokuthola
Kusukela ekulungiseleleni isampula kuya ekwenziweni kombiko wokugcina, yonke inqubo yokuthola imvamisa ithatha izinsuku zokusebenza ezi-3-5. Isikhathi esithile sincike ekusebenzeni kahle kwenhlangano yokuhlola kanye nenani lamasampula.

3. Ukuhunyushwa kwemiphumela yokuhlolwa
Imiphumela yokuhlolwa ivame ukuvezwa ekugxilweni kwe-formaldehyde (mg/m³). Ngokwezindinganiso zomhlaba wonke, umkhawulo wokugxilwa kwe-formaldehyde emoyeni wangaphakathi ngu-0.10 mg/m³. Uma umphumela wokuhlolwa udlula lo mkhawulo, kusho ukuthi okuqukethwe kwe-formaldehyde komkhiqizo kudlula indinganiso futhi kudingeka kuthathwe ezinye izinyathelo.

4. Amanothi Abathengi Bomhlaba Wonke Abathengisa Ngobuningi
Khetha i-ejensi yokuhlola yobungcweti: Qiniseka ukuthi i-ejensi yokuhlola inesitifiketi se-CMA noma se-ISO ukuqinisekisa ukunemba negunya lemiphumela yokuhlolwa.
Gxila ezindinganisweni zokuhlola: Amazwe nezifunda ezahlukene zingase zibe nemikhawulo ehlukene kokuqukethwe kwe-formaldehyde. Abathengi kudingeka bakhethe amazinga okuhlola afanele ngokuya ngezidingo zemakethe eqondiwe.
Ukuhlolwa okuvamile: Kunconywa ukuhlola njalo ama-silicone hip pads ukuze kuqinisekiswe ukuqina kwekhwalithi yomkhiqizo.

5. Isifinyezo
Ukuhlola okuqukethwe kwe-formaldehyde kuma-silicone hip pads kuyinqubo eyinkimbinkimbi kodwa edingekayo. Ngokuqonda inqubo nesikhathi sokuhlola, abathengi bamazwe ngamazwe abathengisa ngobuningi bangahlela kangcono amasu okukhiqiza umkhiqizo kanye nokuthengisa ukuqinisekisa ukuthi imikhiqizo ihlangabezana nezindinganiso zamazwe ngamazwe futhi ihlangabezane nezidingo zabathengi zokuvikela impilo kanye nemvelo.
Ngiyethemba ukuthi lesi sihloko singakunikeza izinkomba ezibalulekile kubathengi bamazwe ngamazwe futhi sikusize wenze izinqumo ezinolwazi ngokuhlolwa komkhiqizo kanye nokulawulwa kwekhwalithi.
