Kuthatha ixesha elingakanani ukuvavanya umxholo we-formaldehyde kwii-silicone hip pads?

Ngenxa yokwanda kwemfuno yehlabathi yeemveliso ezinobuhlobo nokusingqongileyo nezisempilweni, ii-silicone hip pads, njengezinto eziqhelekileyo zasekhaya, ziye zaba yindawo ephambili kubathengi bamazwe ngamazwe abathengisa ngobuninzi. Eli nqaku liza kuhlola ngokweenkcukacha inkqubo, ixesha elifunekayo, kunye namanyathelo afanelekileyo okuvavanya umxholo we-formaldehyde kwii-silicone hip pads ukunceda abathengi bayiqonde ngcono le nkqubo.

1. Imvelaphi yovavanyo lwe-formaldehyde lwee-silicone hip pads
Ukususela kwiipads ze-silicone hipZithambile, zihlala ixesha elide, kwaye zinobuhlobo nokusingqongileyo, zisetyenziswa kakhulu kwifenitshala yasekhaya, kwizitulo zeemoto, nakwifenitshala yeofisi. Nangona kunjalo, ngenxa yeglu okanye ezinye iikhemikhali ezingasetyenziswa kwinkqubo yemveliso, ii-silicone hip pads zinokukhupha i-formaldehyde, enokubangela ingozi kwimpilo yabantu. Ke ngoko, ukuvavanya umxholo we-formaldehyde kwii-silicone hip pads kube linyathelo elibalulekileyo ukuqinisekisa ukuba imveliso iyahlangabezana nemigangatho yamazwe ngamazwe.

2. Inkqubo yovavanyo lwe-formaldehyde
1. Ukulungiselela isampuli
Ngaphambi kovavanyo, kufuneka kulungiswe iisampulu zee-silicone hip pads. Iisampulu kufuneka zikhethwe ngokungacwangciswanga kwibhetshi yemveliso ukuqinisekisa ukuba zimelele. Iisampulu kufuneka zihlanjwe ngamanzi acocekileyo kwaye zivalwe ukuthintela ungcoliseko lwangaphandle.

2. Ixesha elitywiniweyo
Uvavanyo lwe-formaldehyde ludla ngokufuna ukwenziwa kwindawo evaliweyo. Ngokwe-National Indoor Air Quality Standard (GB/T 18883-2002), iingcango kunye neefestile kufuneka zivalwe iiyure ezili-12 ngaphambi kovavanyo ukuqinisekisa ukuba iziphumo zovavanyo zisondele kakhulu ekusetyenzisweni kwangempela.
3. Ukusampula kunye nohlalutyo
Ukufunyanwa kwe-Formaldehyde kudla ngokusebenzisa i-phenol reagent spectrophotometry. Amanyathelo athile aquka:
Ukuthatha iisampulu: Sebenzisa ityhubhu yokufunxa ukuze uqokelele iisampulu zomoya, kwaye ixesha lokuthatha iisampulu limalunga nemizuzu engama-20.
Uphuhliso lombala kunye nokuchonga: Thatha iisampulu eziqokelelweyo uzibuyisele elabhoratri ukuze kuphuculwe umbala kunye nokuchonga ukufunxwa kwawo ukuze kubalwe uxinano lwe-formaldehyde.
4. Ixesha lokufumanisa
Ukususela ekulungiseleleni isampuli ukuya ekwenziweni kwengxelo yokugqibela, yonke inkqubo yokufumanisa idla ngokuthatha iintsuku zokusebenza ezi-3-5. Ixesha elithile lixhomekeke ekusebenzeni kakuhle kwe-arhente yovavanyo kunye nenani leesampuli.

3. Ukutolikwa kweziphumo zovavanyo
Iziphumo zovavanyo zihlala zibonakaliswa kuxinzelelo lwe-formaldehyde (mg/m³). Ngokwemigangatho yamazwe ngamazwe, umda woxinzelelo lwe-formaldehyde yomoya wangaphakathi yi-0.10 mg/m³. Ukuba iziphumo zovavanyo zidlula lo mda, oko kuthetha ukuba umxholo we-formaldehyde kwimveliso udlula umgangatho kwaye kufuneka kuthathwe amanyathelo angaphezulu.

4. Amanqaku kubathengi bamazwe ngamazwe abathengisa ngobuninzi
Khetha i-arhente yovavanyo yobungcali: Qinisekisa ukuba i-arhente yovavanyo inesiqinisekiso se-CMA okanye se-ISO ukuqinisekisa ukuchaneka negunya leziphumo zovavanyo.
Gxila kwimigangatho yovavanyo: Amazwe ahlukeneyo kunye nemimandla inokuba nemida eyahlukileyo kumxholo we-formaldehyde. Abathengi kufuneka bakhethe imigangatho yovavanyo efanelekileyo ngokweemfuno zemarike ekujoliswe kuyo.
Uvavanyo oluqhelekileyo: Kucetyiswa ukuba kuvavanywe rhoqo ii-silicone hip pads ukuqinisekisa uzinzo lomgangatho wemveliso.

5. Isishwankathelo
Ukuvavanya umxholo we-formaldehyde kwii-silicone hip pads yinkqubo enzima kodwa efunekayo. Ngokuqonda inkqubo yokuvavanya nexesha, abathengi bamazwe ngamazwe abanokucwangcisa ngcono amaqhinga okuvelisa imveliso kunye nokuthengisa ukuqinisekisa ukuba iimveliso ziyahlangabezana nemigangatho yamazwe ngamazwe kwaye ziyahlangabezana neemfuno zabathengi zokukhusela impilo kunye nokusingqongileyo.
Ndiyathemba ukuba eli nqaku linokuba luncedo kubathengi bamazwe ngamazwe ngokuthengisa ngobuninzi kwaye likuncede wenze izigqibo ezinolwazi ngakumbi malunga novavanyo lwemveliso kunye nolawulo lomgangatho.
