Kule post yebhlog, siza kujongisisa ukuveliswa kokupakishwa kweplastiki kwaye sichonge ezinye zezinto ezinobungozi ezisetyenzisiweyo.

Hlala ubukele ngakumbi!

Yintoni ukupakishwa kweplastiki?
Ukupakishwa kweplastiki luhlobo lokupakisha olwenziwe ngeplastiki.Isetyenziselwa ukugcina nokukhusela iimveliso kumonakalo kunye nokungcoliswa.

Ukupakishwa kweplastiki ngokuqhelekileyo kukhethwe ngenxa yokuba ilula, iqinile kwaye ixhathisa ukufuma.Isenokucaca okanye ibe nemibala ukubonisa iimveliso ngaphakathi.Ezinye iintlobo zokupakishwa kweplastiki zinokuphinda zisetyenziswe, ngelixa ezinye zingenako.

Yenziwa njani ukupakishwa kweplastiki?
Ukupakishwa kweplastiki kwenziwa ngeepolymers, iimolekyuli zekhonkco elide.Nantsi inkqubo:

inyathelo #1
Iipolymers ziimolekyuli ezinde, kwaye ukupakishwa kweplastiki kwenziwa ngezi polima.Inyathelo lokuqala kwinkqubo kukwenza amatyathanga epolymer.Oku kwenziwa kumzi-mveliso apho izinto ezikrwada zixutywa kwaye zifudunyezwe de zinyibilike.Nje ukuba iipolymers zibe lulwelo, zinokubunjwa zibe yimo efunekayo.

Inyathelo #2
Emva kokuba iintambo zepolymer zenziwe, kufuneka zipholile kwaye ziqiniswe.Oku kwenziwa ngokubagqithisa kuthotho lweerola.Ii-roller zisebenzisa uxinzelelo kwiplastiki etyhidiweyo, ibangela ukuba ibe nzima kwaye ithathe isimo esifunwayo.

Inyathelo #3
Isinyathelo sokugqibela kukudibanisa ukuchukumisa ukugqiba, njengokuprinta okanye iilebhile.Oku kuqhele ukwenziwa ngoomatshini, nangona ukupakishwa okuthile kunokwenziwa ngesandla.Yakuba ipakishwe, ingasetyenziselwa ukugcina nokuthutha imveliso.

Yile ndlela iplastiki eyenziwa ngayo kwipakethe.Le yinkqubo elula kakhulu.Ngoku makhe sibone ukuba zeziphi iikhemikhali ezisetyenziswayo kwinkqubo.

Zeziphi iikhemikhali ezisetyenziswa kwipakethe yeplastiki?
Kukho iintlobo ngeentlobo zeekhemikhali ezinokuthi zisetyenziswe kwipakethe yeplastiki, kodwa ezinye zezona ziqhelekileyo ziquka:

IBisphenol A (BPA):Ikhemikhali esetyenziselwa ukwenza iiplastiki zibe lukhuni kwaye zikwazi ukumelana nokuqhekeka.I-BPA ibonakaliswe ukuba ineempembelelo ezinjenge-hormone kwizilwanyana, kwaye kukho ubungqina bokuba inokubangela iingxaki zempilo ebantwini.
IiPhthalates:Iqela leekhemikhali ezisetyenziselwa ukwenza iiplastiki zithambile kwaye zinwebeka ngakumbi.IiPhthalates ziye zanxulunyaniswa neengxaki ezininzi zempilo, kubandakanya ukuzala nokungachumi.
IiCompounds ezinePerfluorinated (PFCs):Iikhemikhali ezisetyenziselwa ukwenza izinto zokugxotha amanzi kunye ne-oyile kwiiplastiki.I-PFC inxulumene nomhlaza, umonakalo wesibindi kunye neengxaki zokuzala.
IiPlastiki:Iikhemikhali zongezwa kwiiplastiki ukuze zibethambile kwaye zinwebeka ngakumbi.IiPlastiki zinokuphuma kwipakethe kwaye zibe kukutya okanye iziselo.

Ke, ezi zezinye zezona khemikhali zisetyenziswa kakhulu kwipakethe yeplastiki.Njengoko ubona, ezininzi zazo zinokuba yingozi kwimpilo yabantu.Kungenxa yoko le nto kunyanzelekile ukuba siqonde iingozi zokupakishwa kweplastiki kwaye uthathe amanyathelo okukuphepha.

Iinzuzo zokusebenzisa ukupakishwa kweplastiki
Kukho ezinye iingenelo zokusebenzisa ukupakishwa kweplastiki.Ukupakishwa kweplastiki ngokuqhelekileyo kukhethwe ngenxa yokuba:

Khaphukhaphu:Ukupakishwa kweplastiki kulula kunezinye iintlobo zokupakisha ezifana neglasi okanye isinyithi.Oku kwenza ukuthunyelwa kwenqanawa kungabizi kwaye kube lula ukuyiphatha.
Ihlala ixesha elide:Ipakethe yeplastiki yomelele kwaye ayonakaliswa lula.Oku kunceda ukukhusela imveliso ngaphakathi ekuqhekekeni nasekungcoleni.
Ubungqina bokufuma:Ukupakishwa kwePlastiki akunabungqina bokufuma kwaye inceda ukugcina iziqulatho zomile kwaye zintsha.
Inokuphinda isetyenziswe:Iindidi ezithile zokupakishwa kweplastiki zinokuphinda zisetyenziswe, nto leyo enceda ekunciphiseni inkunkuma.
Ke ezi zezinye zezibonelelo zokusebenzisa ukupakishwa kweplastiki.Nangona kunjalo, ukulinganisa ezi zibonelelo kwiingozi ezinokubakho kwimpilo yabantu kubalulekile.

Imingcipheko yokusebenzisa ukupakishwa kweplastiki
Njengoko sele sibonile, kukho imingcipheko emininzi enxulumene nokusebenzisa ukupakishwa kweplastiki.Ezi ziquka:

Imichiza eyiNgozi:Iikhemikhali ezininzi ezisetyenziswa kwipakethe yeplastiki ziyingozi kwimpilo yabantu.Oku kubandakanya i-BPA, i-phthalates kunye ne-PFCs.
Leaching:Iiplastiki zePlastiki zinokuphuma kwipakethe kwaye zifake ukutya okanye isiselo.Oku kwandisa umthamo weekhemikhali ezinobungozi ojongene nazo.
Usulelo:Ukupakishwa kweplastiki kunokungcolisa iziqulatho, ngakumbi ukuba azicocwanga kakuhle okanye azicocwanga.
Ke ezi zezinye zeengozi zokusebenzisa ukupakishwa kweplastiki.Le mingcipheko kufuneka iqwalaselwe phambi kokuba kuthathwe isigqibo sokusebenzisa ukupakishwa kweplastiki.

Ukuqukumbela
Ngelixa amanani achanekileyo kunzima ukuwacinezela, sinokuqikelela ukuba malunga ne-10-20 imichiza efunekayo ukwenza ipakethe yeplastiki eqhelekileyo.

Oku kuthetha iindawo ezininzi zoqhagamshelwano ezinokubakho kwiityhefu ezinobungozi kunye nongcoliseko.

Qhagamshelana nathi ukuba ujonge ukhetho oluzinzileyo kunye nolwaneliseko lokusingqongileyo.
