Ngemva kokuba isiqinisi sishintshiwe kusuka kusawoti oholayo kuya ku-calcium zinc stabilizer, kulula ukuthola ukuthi umbala womkhiqizo uvame ukuba luhlaza okotshani, futhi kunzima ukufeza ushintsho lombala kusuka koluhlaza okotshani kuya kobomvu.
Ngemva kokuba isiqinisi semikhiqizo eqinile ye-PVC siguqulwe kusuka kusawoti we-lead sibe yi-calcium zinc stabilizer, izinkinga zombala nazo ziyinkinga evamile futhi ehlukahlukene okunzima ukuyixazulula. Izimpawu zayo zifaka okulandelayo:
1. Ukufakwa esikhundleni kweziqinisi kuholela ekushintsheni kombala womkhiqizo. Ngemva kokuba isiqinisi sishintshiwe kusuka kusawoti we-lead sibe yi-calcium zinc stabilizer, kulula ukuthola ukuthi umbala womkhiqizo uvame ukuba luhlaza okotshani, futhi kunzima ukufeza ushintsho lombala kusuka koluhlaza okotshani kuya kobomvu.
2. Umbala womkhiqizo ngaphakathi nangaphandle awuguquguquki ngemva kokusebenzisa i-calcium zinc stabilizer. Ngokuvamile, umbala wangaphandle uba muhle kakhulu, kuyilapho umbala wangaphakathi uvame ukuba luhlaza okwesibhakabhaka nokuphuzi. Lesi simo singenzeka kalula kumaphrofayili nasemapayipini.
3. Ukushintshashintsha kombala wemikhiqizo ngesikhathi sokucubungula ngemva kokusebenzisa iziqinisi ze-calcium zinc. Enkambisweni yokusebenzisa iziqinisi ze-lead salt ukucubungula imikhiqizo, kungase kube nokuphambuka kombala phakathi kwemishini ehlukene nangezikhathi ezahlukene ngaphakathi komshini ofanayo, kodwa ububanzi bokushintshashintsha buncane kakhulu. Ngemva kokusebenzisa iziqinisi ze-calcium zinc, lokhu kushintshashintsha kungaba kukhulu, futhi umthelela wokushintshashintsha okuncane ezintweni zokusetshenziswa kanye nezinqubo embala ungase ubonakale kakhulu. Umbhali uhlangane mathupha nezimo lapho amakhasimende esebenzisa iziqinisi ze-calcium zinc ukukhiqiza amapayipi kanye nokufakwa, futhi izinguquko zokucindezela azithinti nje umbala womkhiqizo, kodwa futhi zithinta nokusebenza kwawo. Lolu shintsho lubucayi kakhulu kunalapho kusetshenziswa iziqinisi ze-lead salt.
4. Inkinga yombala wemikhiqizo ngesikhathi sokugcina, ukuthuthwa, kanye nokusetshenziswa ngemva kokusebenzisa iziqinisi ze-calcium zinc ezinobungani nemvelo. Imikhiqizo eqinile ye-PVC esebenzisa iziqinisi ze-lead salt zendabuko ayinawo ushintsho oluncane lombala ngesikhathi sokugcina, ukuthuthwa, kanye nokusetshenziswa. Ngemva kokuguqulwa kube iziqinisi ezinobungani nemvelo ezifana ne-calcium ne-zinc, kungase kube nokuthambekela kokuthi umkhiqizo uphenduke ophuzi noluhlaza okwesibhakabhaka ngemva kokuma. Ezinye iziqinisi zingabangela ukuthi umkhiqizo uphenduke obomvu uma usetshenziswa emikhiqizweni enokuqukethwe okuphezulu kwe-iron ion ku-calcium powder eyengeziwe.
