Isiqinisi seCalcium kunye neZinc
Isiqinisi seCalcium kunye neZinc
Ngokuphuculwa kolwazi lokhuseleko lokusingqongileyo kuwo onke amazwe ehlabathini, imithetho nemigaqo yokhuseleko lokusingqongileyo iphuculwa kancinci kancinci, ngakumbi iimfuno zococeko kwiimveliso zeplastiki ezifana namayeza, ukulungiswa kokutya, izinto ezifunekayo zemihla ngemihla, kunye neeplastiki zokudlala. Iziqinisi zetyuwa ye-lead kunye ne-cadmium ekugqibeleni ziya kuthathelwa indawo ngokupheleleyo ziziqinisi ze-PVC ezingezizo ezinobungozi. . Ukuveliswa kwezongezo zeplastiki zangaphandle kuya kuba kukhulu kwaye kukhetheke, iimfuno zokhuseleko lokusingqongileyo zixatyiswa kakhulu, kwaye zisebenza kakuhle kwaye zisebenza ngeendlela ezininzi. Uphando kunye nophuhliso lweziqinisi ezintsha ze-PVC ezinobuhlobo nokusingqongileyo kunye nezingezizo ezinobungozi kuye kwaba yinto engenakuphepheka. Ulwalathiso olungenabungozi lweziqinisi zobushushu ze-PVC lugxile kakhulu kwiinkalo ezimbini zeziqinisi zobushushu ezihlanganisiweyo ze-organotin kunye ne-calcium-zinc, kwaye kwenziwe inkqubela phambili enkulu kuzo zombini. Oku kubonakala kakhulu kuphando oluphumeleleyo kunye nokusetyenziswa okukhulu kweziqinisi zobushushu ze-organotin ezimelwe yi-United States, kunye nokuthandwa kunye nokusetyenziswa kweziqinisi zobushushu ezihlanganisiweyo ze-calcium-zinc ezihlanganisiweyo ezimelwe yiYurophu, kodwa ixabiso le-organotin libiza kakhulu. Isiqinisi se-calcium-zinc ekugqibeleni siya kwakha inkqubo ye-PVC yokuzinzisa yexesha elizayo engezizo ezinobungozi kuwo onke amazwe ehlabathini.
Isetyenziswa kwiipayipi, iiprofayili, izixhobo zepayipi, iipleyiti, ukubumba ngenaliti, ifilimu yokubumba ngokuvuthela, izinto zekhebula kunye nezinye iimveliso zeplastiki;
| uphawu | isalathisi |

1. Isiqinisi sokukhusela okusingqongileyo esiluhlaza ngokwenene;
2. Uzinzo oluhle kakhulu lobushushu;
3. Nika isizalisi ithuba elihle lokusasazeka kwaye uphucule iipropati zoomatshini zemveliso;
4. Nciphisa ukuguguleka koomatshini kwaye wandise ubomi benkonzo yezixhobo;
5. Ingasetyenziselwa iimveliso ezicacileyo kwaye inika iimveliso amandla okungena kakuhle.
