Emva kokuba isiqinisi sitshintshiwe ukusuka kwityuwa yelothe ukuya kwi-calcium zinc stabilizer, kulula ukufumanisa ukuba umbala wemveliso uhlala uluhlaza, kwaye kunzima ukufikelela kutshintsho lombala ukusuka koluhlaza ukuya kobomvu.
Emva kokuba isizinzisi seemveliso zePVC eziqinileyo siguqulwe ukusuka kwityuwa yelothe ukuya kwi-calcium zinc stabilizer, iingxaki zombala nazo ziyingxaki eqhelekileyo neyahlukeneyo ekunzima ukuyisombulula. Iimpawu zayo ziquka oku kulandelayo:
1. Ukutshintshwa kwezithambisi kukhokelela kutshintsho kumbala wemveliso. Emva kokuba isithambisi sitshintshiwe ukusuka kwityuwa yeloti ukuya kwi-calcium zinc stabilizer, kulula ukufumanisa ukuba umbala wemveliso uhlala uluhlaza, kwaye kunzima ukufikelela kutshintsho lombala ukusuka koluhlaza ukuya kobomvu.
2. Umbala wemveliso ngaphakathi nangaphandle awuhambelani emva kokusebenzisa i-calcium zinc stabilizer. Ngokwesiqhelo, umbala wangaphandle uba mhle, ngelixa umbala wangaphakathi uba luhlaza okwesibhakabhaka kwaye ube tyheli. Le meko inokwenzeka ngokulula kwiiprofayili kunye nemibhobho.
3. Ukutshintsha kombala weemveliso ngexesha lokucubungula emva kokusebenzisa iziqinisi ze-calcium zinc. Kwinkqubo yokusebenzisa iziqinisi zetyuwa ye-lead ukucubungula iimveliso, kunokubakho ukuphambuka kombala phakathi koomatshini abahlukeneyo nangamaxesha ahlukeneyo ngaphakathi komatshini omnye, kodwa uluhlu lokuguquguquka luncinci kakhulu. Emva kokusebenzisa iziqinisi ze-calcium zinc, olu tshintsho lunokuba lukhulu, kwaye impembelelo yokuguquguquka okuncinci kwizixhobo ezikrwada kunye neenkqubo kumbala nayo ingabonakala ngakumbi. Umbhali udibene neemeko apho abathengi basebenzisa iziqinisi ze-calcium zinc ukuvelisa imibhobho kunye nezinto ezifakelwayo, kwaye utshintsho loxinzelelo aluchaphazeli kuphela umbala wemveliso, kodwa luchaphazela nokusebenza kwayo. Olu tshintsho lunobuthathaka ngakumbi kunaxa kusetyenziswa iziqinisi zetyuwa ye-lead.
4. Umba wombala weemveliso ngexesha lokugcina, ukuthuthwa, kunye nokusetyenziswa emva kokusebenzisa iziqinisi ze-calcium zinc ezinobuhlobo nokusingqongileyo. Iimveliso ze-PVC eziqinileyo ezisebenzisa iziqinisi zetyuwa ye-lead zendabuko azinatshintsho lukhulu lombala ngexesha lokugcina, ukuthuthwa, kunye nokusetyenziswa. Emva kokuguqulwa zibe ziziqinisi ezinobuhlobo nokusingqongileyo ezifana ne-calcium kunye ne-zinc, kunokubakho umkhwa wokuba imveliso ijike ibe tyheli kwaye ibe luhlaza okwesibhakabhaka emva kokuma. Ezinye iziqinisi zinokubangela ukuba imveliso ijike ibe bomvu xa isetyenziswa kwiimveliso ezinomxholo ophezulu we-iron ion kwi-calcium powder eyongeziweyo.
