Iiplastiki ezilahlwayo yile nto siyibiza ngokuba zizixhobo ezisetyenzisiweyo, kodwa xa sithelekisa, ukusebenza ngokubanzi kunye neempawu zeplastiki ezilahlwayo azilunganga njengemathiriyeli emitsha kunye nemathiriyeli ehlaziyiweyo.Kodwa ayizizo zonke iimveliso zeplastiki ezifuna ukusebenza okubanzi.
Ngokweemfuno zokusebenza zemveliso ethile yeplastiki, inkunkuma yeplastiki inokuphinda isetyenziswe kwaye isetyenziswe kwakhona kwaye igcine izibonelelo ukuba nje uphawu olulodwa lwenkalo ethile lusetyenzwa ukuze luvelise iimveliso zeplastiki ezihambelanayo.
Ixabiso lenkunkuma yeplastiki lixabiso eliphantsi kakhulu, kwaye umgangatho walo awuyi kuba yingxaki.Nangona kunjalo, ngenxa yeemeko ezahlukeneyo zokusingqongileyo kunye nesenzo somntu, inkunkuma yeplastiki inenkangeleko engwevu kunye nokuba tyheli.Iimveliso eziveliswa ngaphandle kwonyango zinembonakalo emnyama ephuzi kunye nokuchasana kwemozulu embi, echaphazela kakhulu ukuthengisa.
Ukuze ucombulule iingxaki zeemveliso eziveliswe ngenkunkuma yeplastiki, njengombala omthubi omnyama kunye nokumelana nemozulu embi, abaninzi abavelisi baya kukhetha ukongeza izongezo ezahlukeneyo zokuphucula umgangatho wemveliso.
Phakathi kwabo, i-agent emhlophe ye-fluorescent ibaluleke kakhulu kwinkqubo yokuvuselela iiplastiki zenkunkuma.Emva kokongeza inkunkuma yeemveliso zeplastiki kunye ne-agent emhlophe ye-fluorescent, ubumhlophe kunye nokukhanya kweemveliso kuphuculwe kakhulu.Kutheni le nto kuphela i-agent emhlophe ye-fluorescent enokwenza inkunkuma yeplastiki ibonakale intsha?Ngenxa yokuba umsebenzi okhethekileyo we-fluorescent we-fluorescent arhente inokufunxa ukukhanya kwe-ultraviolet ekukhanyeni kwendalo, kwaye emva koko uyiguqule ibe yi-blue-violet fluorescence kwaye uyikhuphe.Iblue and yellow yimibala ehambelanayo.Xa amaza okukhanya akhutshwa zezi zimbini efana, ukukhanya okuluhlaza okwesibhakabhaka kunye nomxube wokukhanya otyheli ukuvelisa ukukhanya okumhlophe, ngoko ke i-agent emhlophe ye-fluorescent inokwenza imveliso ibe tyheli namhlophe.Imitha ye-ultraviolet ayibonakali kwiliso lenyama.Xa iguqulwa ibe kukukhanya okuluhlaza okwesibhakabhaka, inyusa inani elipheleleyo lokubonakaliswa kwento, ngaloo ndlela ibe nefuthe eliqaqambileyo.
Ngoko ke, ekubeni i-agent emhlophe ye-fluorescent ingaba nefuthe lokuba mhlophe kunye nokukhanya, ngaba naluphi na uhlobo lwe-agent emhlophe ye-fluorescent ilungele ukusetyenziswa kwiiplastiki zenkunkuma?Kukho iintlobo ezininzi zezikhanyisi ze-fluorescent.Kwiimveliso ezineempawu ezahlukeneyo, kuphela uhlobo oluchanekileyo lokukhanyisa lunokusetyenziswa ukwenza isikhanyiso se-fluorescent senze umphumo walo ongcono.
Kukho neentlobo ezininzi ze-fluorescent whitening agents ezisetyenziswa kwinkunkuma yeemveliso zeplastiki kwimarike.Iiplastiki zenkunkuma ngokubanzi zisebenzisa i-agent emhlophe ye-fluorescent i-OB-1, kwiimeko ezikhethekileyo i-127 okanye i-agent e-fluorescent emhlophe i-OB iya kusetyenziswa.Ke zithini iimpawu zale mifuziselo mithathu yenkunkuma yeplastiki?1. Ixabiso le-optical brightener OB-1 lisondele kubantu.Ubumhlophe buhle, kwaye ukongeza okuncinci kuya kuba nobumhlophe obuhle.Ukungalungi kukuba iglue ethambileyo kufuneka isetyenziswe ngononophelo.2. I-Flighter FP-127 yenza ukunqongophala kwe-OB-1 kwizinto zeplastiki ezithambileyo zePVC, kwaye ifaneleke ngakumbi kwi-PVC ethambileyo yeplastiki.3. Ukuba iplastiki ebonakalayo okanye iplastiki ekhethekileyo, cinga ukusebenzisa i-OB, kuba i-OB inokuhambelana kakuhle, ukumelana nemozulu entle, kunye noluhlu olubanzi lwezicelo.
