Ingozi yokugquma umgubo

Yintoni na yengubo ingozi?

Uninzi lweereyini zokugquma ngomgubo aziyotyhefu kwaye ziyingozi, kwaye iarhente yokunyanga inetyhefu ngakumbi kunentlaka. Nangona kunjalo, xa yenziwe i-powder coating, ityhefu ye-ejenti yokunyanga iba yincinci kakhulu okanye iphantse ingabi yityhefu. Uvavanyo lwezilwanyana lubonise ukuba akukho zimpawu zokufa kunye nokulimala emva kokuphefumla i-powder coating, kodwa kukho amanqanaba ahlukeneyo okucaphuka kwamehlo kunye nolusu.

Nangona i-general I-powder coatings ayinayo ingozi ecacileyo emzimbeni womntu, inokubangela ukucaphuka kunye ne-allergies emva kokuba incanyathiselwe eluswini lomntu, amehlo kunye nephecana lokuphefumla.

Imisebenzi yokuvelisa kwiminyaka edlulileyo ibonise ukuba i-triglycidyl methacrylate (TGIC) inefuthe elibalulekileyo lokuvuselela ulusu kunye ne-biomass eguqukileyo kwiimeko ezimanzi.

Ngokutsho kophando lwaseYurophu, i-TGIC iqinisekisiwe ukuba yinto enobuthi, kwaye uphawu lwemveliso eyingozi lubonakaliswe kuphawu lwemveliso. Isixa esisetyenzisiweyo kwi-powder coating siye sancitshiswa kakhulu, kwaye inxalenye enkulu yatshintshwa nge-agent ephilisayo efana ne-hydroxyalkylamide.

E-China, siye saqaphela ngokuthe ngcembe ingozi yetyhefu ye-TGIC, kwaye sakhuthaza ukusetyenziswa kwee-acylating agents ze-hydroxyalkyl acylating, kwaye idosi yayo iyanda, kodwa ukuxhathisa ubushushu kunye neepropati ezishinyeneyo zokugquma komgubo wenziwa kunye nale arhente yokunyanga. Kusekho iingxaki, kwaye abantu bayayamkela ngesantya esiphantsi. Ndiyakholelwa ukuba ilizwe liya kunika ingqwalasela engakumbi kumsebenzi wokukhusela okusingqongileyo kwixesha elizayo.

Ingozi yokugquma umgubo ibonakala, iyingozi kakhulu kumzimba womntu. Kutheni ilizwe lingayeki ukuvelisa iingubo zomgubo? Kuba ngoku onke amashishini awanakwahlulwa kolu gquba lomgubo.

Nangona i-powder coatings ayinayo ubutyhefu obucacileyo, ukuphefumla kwi-trachea kunye nemiphunga kuseyingozi kumzimba womntu. Ukuba ukufunxa ngokugqithisileyo kunokubangela ukubekwa kwe-silicon (eyayibizwa ngokuba yi-silicosis), ezi ngxaki zilandelayo kufuneka ziqatshelwe kwimveliso kunye nokwaleka kweengubo zomgubo:

1. Kwimveliso yomgubo wepowder kunye neworkshop yokupeyinta, indawo yokwakha kufuneka igcinwe icocekile rhoqo ukuze kuthintelwe ukuvuza kothuli lwezixhobo kunye nothuli kwindawo yokusebenzela, kwaye kubekho umoya omhle; kwizixhobo kunye namacandelo athambekele eluthulini, kufuneka kubangele iimeko zoxinzelelo olubi, ngokukhethekileyo Faka isixhobo esikhethekileyo sokususa uthuli kwaye uvule izixhobo zokususa uthuli xa kuyimfuneko.
2. Nxiba iiglavu zokukhusela, iikepusi zokusebenza, i-overalls kunye neemaski zothuli ngexesha leeyure zokusebenza ukukhusela umgubo wokugquma ukuba ungabambeleli eluswini nakwindlela yokuphefumla.
3. Xa umsebenzi wokuvelisa uphelile, vuthela uthuli olufakwe emzimbeni ngexesha, kwaye uhlambe uthuli ebusweni nasezandleni ngexesha.
4. Kwiyunithi enemiqathango, emva kokuba umqeshwa eshiya umsebenzi, kufuneka ahlambe ubuso bakhe, ahlambe iinwele zakhe, ahlambe, atshintshe i-ove yakhe.ralls, kwaye uphephe ukukhupha uthuli kwindawo yokusebenzela, nto leyo ebangela ungcoliseko olungeyomfuneko.
