Ngexesha lokucubungula iimveliso ze-PVC eziqinileyo, ingxaki yombala nayo yingxaki eqhelekileyo neyahlukeneyo ekunzima ukuyisombulula xa isiqinisi sitshintsha ukusuka kwityuwa yelothe ukuya kwi-calcium zinc stabilizer. 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.
Isizathu esiphambili seengxaki zombala ezingentla kukuba ulwakhiwo lwe-calcium zinc stabilizers luyinkimbinkimbi, kwaye ukuzinza kobushushu kumanqanaba okuqala, aphakathi, kunye nawamva kufezekiswa ngokulungelelaniswa kwezinto ezininzi ezikrwada. Icandelo ngalinye linempembelelo ethile kumbala wemveliso, kwaye ukudityaniswa kwezinto ezininzi kudala amathuba ahlukeneyo. Kwangaxeshanye, uxinzelelo lwemarike luye lwakhokelela abanye abavelisi be-stabilizers ukuba basebenzise izinto ezikrwada ezingahambelaniyo, nto leyo eyenza kube nzima ngakumbi ukuntsonkotha kwengxaki. Ukusombulula ingxaki ngokupheleleyo, akufuneki nje kuphela ukuhlalutya iingxaki ezithile, kodwa kwanamashishini okucubungula imveliso ye-PVC asezantsi kufuneka akhethe ngononophelo amashishini amakhulu nanophawu oludumileyo.
Uthelekiso lomahluko ophambili: Iziqinisi zetyuwa yelead zisetyenziswa kakhulu ngenxa yeempawu zazo zokugquma umbane ezibalaseleyo kunye nexabiso eliphantsi, kodwa zineengxaki zobungozi obuphezulu kunye nongcoliseko lothuli.
