Ngaba ukubunjwa kwenaliti yeemveliso zeplastiki kuyityhefu kwaye kukhuselekile?

Iplastikiisitofu sokubumbangokwayo ayiyona inkqubo enetyhefu okanye eyingozi, kodwa ngexesha lenkqubo yokuvelisa, ezinye iikhemikhali kunye neemeko zokusebenza zinokubandakanyeka ukuba, ukuba azilawulwa ngokufanelekileyo kwaye zilawulwa, zinokuba nemiphumo emibi kwimpilo yabasebenzi kunye nokusingqongileyo.

Ibandakanya ikakhulu le miba mithathu ilandelayo:

1Ukongezelela, ezinye izinto zeplastiki eziluhlaza zinokubola ngexesha lokucubungula ukuvelisa izinto ezinobungozi, ezifana ne-vinyl chloride, i-styrene, njl.

(2) Izongezo kunye nezincedisi ezisetyenziswe kwinkqubo yokubumba i-injection yeemveliso zeplastiki, ezifana ne-plasticizers, i-stabilizers, i-lubricant, njl., ingaba nefuthe kwimpilo yabantu.Ezi zinto zihlala zinempembelelo encinci kumzimba womntu kwindawo ephantsi, kodwa zinokuba yingozi kwimpilo yabantu ukuba zirholiwe, zifakwe okanye zivezwe eluswini ngobuninzi.

(3) Inkqubo yokubunjwa kwenaliti yeemveliso zeplastiki iya kuvelisa ingxolo kunye nokungcangcazela, ukuba abasebenzi bavezwe kwezi zinto ixesha elide, kunokukhokelela ekulahlekelweni kokuva kunye nokudinwa komzimba.

Ukuqinisekisa ukhuseleko lwenkqubo yokubumba inaliti yeemveliso zeplastiki, kufuneka kuthathwe uthotho lwamanyathelo, ingakumbi oku kuquka le miba mithathu ilandelayo:

(1) Amashishini kufuneka aqinise ulawulo lwezempilo emsebenzini kwaye abonelele ngoqeqesho oluyimfuneko lwezempilo emsebenzini kunye nezixhobo zokukhusela, ezinjengeeglavu, iimaski, iindlebe, njl.

(2) Ukuhlolwa okungenayo kunye nokwamkelwa kwezinto eziluhlaza kufuneka kuqiniswe ukuqinisekisa ukuba izinto ezisetyenzisiweyo ezisetyenzisiweyo zihlangabezana nemigangatho efanelekileyo yesizwe neyendawo.

(3) Amashishini kufuneka alungiselele ngokufanelekileyo inkqubo yokuvelisa kunye noyilo lwezixhobo, anciphise ingxolo kunye nokungcangcazela kwinkqubo yokuvelisa, kwaye aphephe ukubonakaliswa okugqithisileyo kwabasebenzi.

Ngamafutshane, iplastikiisitofu sokubumbainkqubo ngokwayo ayiyona inkqubo enetyhefu kwaye iyingozi, kodwa kuyimfuneko ukunikela ingqalelo ekukhuselweni kwempilo yomntu, ukuhlolwa kwezinto eziluhlaza, ukuhlelwa kwezixhobo kunye nokulawula ingxolo kwinkqubo yokusebenza ukukhusela impilo yabasebenzi kunye nokhuseleko lokusingqongileyo.
