Calcium ndi Zinc Stabilizer

Ndi kupititsa patsogolo chidziwitso cha chitetezo cha chilengedwe m'mayiko onse padziko lapansi, malamulo ndi malamulo oteteza chilengedwe amasinthidwa pang'onopang'ono, makamaka zofunikira zaukhondo pazinthu zapulasitiki monga mankhwala, kukonza chakudya, zofunikira za tsiku ndi tsiku, ndi mapulasitiki a chidole.Ma lead ndi cadmium salt stabilizers pamapeto pake adzalowetsedwa m'malo ndi zolimbitsa thupi zopanda poizoni za PVC..Kupanga zowonjezera za pulasitiki zakunja kudzakhala kwakukulu komanso kwapadera, zofunikira zoteteza chilengedwe ndizofunika kwambiri, zogwira mtima komanso zogwira ntchito zambiri.Kafukufuku ndi chitukuko cha zokhazikika zatsopano za PVC zokondera zachilengedwe komanso zopanda poizoni zakhala njira yosapeŵeka.Mayendedwe osakhala poizoni a PVC heat stabilizers amakhazikika kwambiri m'magawo awiri a organotin ndi calcium-zinc composite heat stabilizers, ndipo kupita patsogolo kwakukulu kwachitika mu zonse ziwiri.Zimawonetsedwa makamaka mu kafukufuku wopambana komanso kugwiritsa ntchito kwambiri organotin kutentha stabilizers akuimiridwa ndi United States, ndi kutchuka ndi ntchito sanali poizoni kashiamu-zinki gulu kutentha stabilizers akuimiridwa ndi Europe, koma mtengo wa organotin ndi okwera mtengo kwambiri.Calcium-zinc composite stabilizer pamapeto pake idzapanga dongosolo lamtsogolo lopanda poizoni la PVC la mayiko onse padziko lapansi.
