Yeyiphi iMathiriyeli eKhuselekileyo kwiindebe zamanzi zePlastiki

Kwihlabathi lanamhlanje elikhawulezayo, ukulungeleka kweekomityi zamanzi zeplastiki zamkelwe kakuhle. Nangona kunjalo, phakathi koku kulula kukho i-labyrinth yemibuzo malunga nokhuseleko lwabo, ngakumbi malunga nemathiriyeli eyenziwe ngayo. Eli nqaku lijolise ekuqhekekeni kunye nokuthelekisa izinto ezahlukeneyo zeplastiki zeklasi zokutya eziqhelekileyo ezisetyenziselwa ukuveliswa kwekomityi yamanzi, ukukhanya kwiiprofayili zabo zokhuseleko kunye nefuthe kwimpilo yabantu.

Intshayelelo

Iikomityi zamanzi zeplastiki zidityaniswe ngaphandle komthungo kubomi bethu bemihla ngemihla, zisebenza njengeenqanawa eziyimfuneko zokuhambisa amanzi. Nangona kunjalo, njengoko abathengi besiya beqaphela ngakumbi imiba yezempilo kunye nokusingqongileyo, ukhuseleko lwezi ndebe luphantsi koqwalaselo. Ukuqonda ama-nuances ezinto ezahlukeneyo zeplastiki ezisetyenziswa kwimveliso yekomityi kubalulekile ekwenzeni ukhetho olunolwazi olubeka phambili impilo kunye nokuzinza.

Polyethylene Terephthalate (PET)

I-Polyethylene terephthalate (PET) yiplastiki esetyenziswa ngokubanzi eyaziwa ngokucaca, ukukhanya, kunye nokuphinda kusetyenziswe. Iikomityi zamanzi ze-PET zithandwa ngokulula kwazo kunye nokufikeleleka kwazo, zihlala zifumaneka koomatshini bokuthengisa, iivenkile eziluncedo, kunye nemisitho. Ngelixa i-PET ngokuqhelekileyo igqalwa njengekhuselekile kwizicelo zokusetyenziswa kanye, kukho iinkxalabo malunga nokuba nokwenzeka kwayo kwiikhemikhali ezivuzayo, ngakumbi xa zisesichengeni sobushushu obuphezulu okanye iziselo ezineasidi. Ke ngoko, iikomityi ze-PET zifaneleke kakhulu kwiziselo ezibandayo okanye zobushushu begumbi ukunciphisa umngcipheko wokufuduka kweekhemikhali.

Polypropylene (PP)

I-Polypropylene (PP) yiplastiki eguquguqukayo exatyiswa ukuxhathisa ubushushu, ukuqina, kunye nenqanaba lokutya. Iikomityi zamanzi zePP ziqhele ukusetyenziswa kwiindawo zokutyela, iikhefi, kunye nemizi, zixatyiswa ngokomelela kwazo kunye nokufaneleka kwazo zombini iziselo ezishushu nezibandayo. I-PP izinzile ngokwemvelo kwaye ayifaki iikhemikhali ezinobungozi phantsi kweemeko eziqhelekileyo, okwenza kube yinto ekhethiweyo yokutya kunye nezitya zesiselo.

Ipolystyrene (PS)

Iikomityi zePolystyrene (PS), ezihlala zibonwa njengeStyrofoam, zibonelela ngeengenelo ezininzi kwiimeko ezithile zokusetyenziswa. Ubume babo obukhaphukhaphu bubenza balungele iminyhadala, ipikniki, kunye neendibano zangaphandle, apho ukuphatheka kubalulekile. Ukongeza, iikomityi ze-PS ziqhayisa ngeempawu ezintle zokugquma, ukugcina iziselo kumaqondo obushushu afunekayo ixesha elide. Eli nqaku libenza babe lolona khetho lukhethiweyo lokusebenzisa iziselo ezishushu njengekofu kunye neti, ukuqinisekisa ukuba iziselo zihlala zishushu kwaye zonwaba. Ngaphezu koko, iikomityi ze-PS zinexabiso eliphantsi, zizenza zibe yinto ebonakalayo kwiziganeko ezinkulu okanye amashishini afuna izisombululo zezoqoqosho ngaphandle kokunciphisa umgangatho.

 
Uhlalutyo oluthelekisayo lweekomityi zeplastiki zeBanga lokutya

Xa kuziwa ekukhetheni izinto ezisemgangathweni zokutya kwiikomityi zamanzi, uhlalutyo oluthelekisayo lunokunceda ukucacisa amandla kunye nobuthathaka bokhetho ngalunye.

1. Ukhuseleko kunye nozinzo:

• I-Polyethylene Terephthalate (PET): Iikomityi ze-PET zinika ibhalansi yokhuseleko kunye nokulula. Ziyamkelwa ngokubanzi njengekhuselekile kwizicelo zokusetyenziswa kunye kwaye zifanelekile kwiziselo ezibandayo. Nangona kunjalo, kucetyiswa ukuba ulumke xa usebenzisa iikomityi ze-PET ezinolwelo olushushu okanye iziselo ezine-asidi ngenxa yesakhono sokukhupha imichiza.
• Ipolypropylene (PP): Iikomityi zePP zaziwa ngokuzinza kwazo kunye nokuchasana nokukhutshwa kweekhemikhali, nto leyo ezenza zibe lukhetho olukhethwayo lokutya kunye nezitya zesiselo. Zinezinto ezininzi, zomelele, kwaye zilungele zombini iziselo ezishushu nezibandayo, nto leyo ezenza ukuba zibe lukhetho oluguquguqukayo kwiisetingi ezahlukeneyo.
• Ipolystyrene (PS): Iikomityi ze-PS zibonelela ngokulula kunye nokufakwa kwe-thermal okugqwesileyo. Iikomityi ze-PS zihlala zithandwa kwizicelo ezithile apho iindleko-ukusebenza kunye neempawu zokugquma zigqithise ukuqwalaselwa kwexesha elide lempilo.

2. Impembelelo yokusingqongileyo:

• I-Polyethylene Terephthalate (PET): Iikomityi ze-PET ziphinda zisetyenziswe ngokubanzi, zinegalelo ekunciphiseni impembelelo yokusingqongileyo xa zilahlwa ngokuchanekileyo. Nangona kunjalo, usetyenziso lwabo olunye kunye nokunciphisa ukuphinda kusetyenziswe kwakhona kubangela imingeni ekujonganeni nongcoliseko lweplastiki.
• Ipolypropylene (PP): Iikomityi zePP ziyaphinda zisetyenziswe kwaye zinokuphinda zisetyenziswe kwiimveliso ezahlukeneyo, kuncitshiswe indawo yazo yokusingqongileyo. Ukomelela kwazo kunye nokubanakho ukuphinda zisetyenziswe kuzenza zibe lukhetho oluzinzileyo xa kuthelekiswa nosetyenziso olunye.
• Ipolystyrene (PS): Iikomityi ze-PS, ngelixa zikhaphukhaphu kwaye zingabizi kakhulu, zibeka imingeni ngokubhekiselele kuhlaziyo kunye nefuthe lokusingqongileyo. Ukurisayiklishwa kwazo okuphantsi kunye nokuzingisa kokusingqongileyo kugxininisa imfuneko yezinye iindlela ezibeka phambili uzinzo.

3. Ukuguquguquka nokuSebenzisa:

• I-Polyethylene Terephthalate (PET):Iikomityi ze-PET zibonelela ngokulula kunye nokufikeleleka, zizenza zilungele iminyhadala, amatheko, kunye nokusetyenziswa ekuhambeni.
• Ipolypropylene (PP): Iikomityi zePP zigqamile ngenxa yokuguquguquka kwazo, ukuzinza, kunye nokufaneleka kweziselo ezahlukahlukeneyo, kuquka neziselo ezishushu. Ukomelela kwabo kunye nokuchasana nokukhutshwa kweekhemikhali kubenza babe lukhetho olusebenzayo lokusetyenziswa kwemihla ngemihla ezindlini, kwiindawo zokutyela, nakwiikhefi.
• Ipolystyrene (PS): Iikomityi ze-PS zigqwesa kwiimeko apho ukuphatheka okulula kunye nokufakwa kwe-thermal kubalulekile, njengeziganeko zangaphandle okanye ukusekwa kokutya okukhawulezayo. Nangona kunjalo, ukufaneleka kwabo okulinganiselweyo kokurisayikilisha kunye neenkxalabo zempilo ezinokubakhona kufuna ukuba kuqwalaselwe ngononophelo ezinye iindlela.

Ukukhethwa kwezixhobo zomgangatho wokutya kwiikomityi zamanzi kubandakanya ukulinganisa izinto ezahlukeneyo, kubandakanya ukhuseleko, ifuthe lokusingqongileyo, ukuguquguquka, kunye nokusebenza. Ngelixa ukhetho ngalunye lubonelela ngeenzuzo ezahlukeneyo, abathengi kufuneka babeke phambili izinto abazithandayo kunye neenqobo ezisemgangathweni ukwenza izigqibo ezinolwazi ezihambelana nempilo yabo kunye neenjongo zozinzo.
