Izici ezithonya ukukhishwa kwefenisha ye-formaldehyde ziyinkimbinkimbi. Ngokuphathelene nesisekelo salo, iphaneli esekwe ngokhuni, kunezici eziningi ezithinta ukukhishwa kwe-formaldehyde yephaneli esekwe ngokhuni, njengohlobo lwezinto ezibonakalayo, uhlobo lweglue, ukusetshenziswa kweglue, izimo zokucindezela ezishisayo, ukwelashwa kwangemva kokwelashwa, njll. Njengokukhishwa kwe-formaldehyde ifenisha, kubalulekile ukugcizelela izici ezinhlanu ezilandelayo:
1. Imodi yokuhlobisa
Umhlobiso ongaphezulu wefenisha unomphumela osobala wokuvala i-formaldehyde. Enkambweni ethile yokuqaliswa, ukunakwa kufanele kukhokhwe ekukhethweni kwe-adhesives nge-low formaldehyde emission, izinto ezihlukahlukene zokuhlobisa kanye nezingubo kanye nenqubo enengqondo yokuqinisekisa ukuthi akukho kukhishwa okusha kwe-formaldehyde okuzobangelwa ngemva kokuhlobisa.
2. Izinga lokulayisha
Okubizwa ngokuthi izinga lokuthwala libhekisela esilinganisweni sendawo engaphezulu yefenisha yasendlini evezwe emoyeni kumthamo wangaphakathi. Uma izinga lokulayisha liphezulu, izinga lokuhlushwa kwe-formaldehyde liphezulu. Ngakho-ke, lapho umsebenzi usunelisekile ngokuyisisekelo, inombolo kanye nevolumu yefenisha endaweni yangaphakathi kufanele kuncishiswe ngangokunokwenzeka, ukuze kuncishiswe ukukhishwa kwe-formaldehyde kufenisha.
3. Indlela yokusabalalisa
Kuyafaneleka ukugcizelela ukuthi ukubaluleka panel ifenisha onqenqemeni. Ngesikhathi esifanayo, ekwakhiweni kwefenisha, ngaphansi kwesisekelo sokuhlangana namandla nesakhiwo, singazama ukusebenzisa amapuleti amancane.
4. Imvelo
Izimo zangempela zokusebenzisa imvelo zinethonya elikhulu ekukhishweni kwefenisha ye-formaldehyde. Izinga lokushisa, umswakama kanye nokukhipha umoya konke kuthinta ukukhishwa kwe-formaldehyde. Ngaphansi kwezimo zezulu ezivamile, ukugxila kwe-formaldehyde emoyeni kuzophindeka kabili lapho izinga lokushisa lenyuka ngo-8 ℃; ukukhishwa kwe-formaldehyde kuzokwenyuka cishe ngo-15% lapho umswakama ukhuphuka ngo-12%. Ngakho-ke, ngokwesisekelo sezimo, isimo somoya kanye namadivayisi wesistimu yomoya omusha angasetshenziswa ukulungisa izinga lokushisa lasendlini, umswakama kanye nevolumu yomoya omusha, ukuze ukukhishwa kwe-formaldehyde kulawulwe ngokusesilinganisweni.
5. Isikhathi nezimo
Ukugcwala kwefenisha ye-formaldehyde kwakuhlotshaniswa kahle nesikhathi sokuguga ngemuva kokukhiqizwa. Ngakho-ke, kufanele igcinwe isikhathi esithile ngaphambi kokusetshenziswa, futhi ibekwe endaweni eshisa kakhulu kanye nomswakama ngesikhathi sokugcinwa ukuze kusheshiswe ukukhishwa kwe-formaldehyde, ukuze kuncishiswe ukungcola ekusetshenzisweni kamuva.
