Mphamvu yogwirizana ya organic tin ndi ufa wa calcium zinc stabilizers mu polyvinyl chloride (PVC)

Mphamvu yogwirizana ya organic tin ndi ufa wa calcium zinc stabilizers mu polyvinyl chloride (PVC):

Zolimbitsa tin za organic (thiol methyl tin) ndi mtundu wa PVC heat stabilizer womwe umagwiritsidwa ntchito kwambiri. Zimayanjana ndi acidic hydrogen chloride (HCl) mu PVC kuti zipange mchere wosavulaza (monga tin chloride), motero zimaletsa kusonkhana kwa HCl ndikuchepetsa kuwonongeka ndi chikasu cha zinthu za PVC.

Ufa wa calcium zinc stabilizer ndi chisakanizo cha mchere wa calcium ndi zinc, nthawi zambiri umawonjezeredwa mu mawonekedwe a ufa wabwino ku PVC. Ma ion a calcium ndi zinc onse ali ndi mphamvu yokhazikitsa PVC. Ma ion a calcium amatha kuletsa zinthu za acidic zomwe zimapangidwa mu PVC ndikupanga mankhwala okhazikika a calcium salt. Ma ion a zinc amachitapo kanthu ndi hydrogen peroxide (HCl) mu PVC kuti apange mankhwala osavulaza komanso kupewa kusonkhana kwa HCl.

Ngati zinthu zokhazikika za calcium zinc ndi ufa wa organic tin ndi ufa wa calcium zinc zimagwirizana mu PVC, zimatha kulimbikitsana ndikuwonjezera luso lochiza HCl. Organic tin ingapereke mphamvu yowonjezera yochepetsera HCl yopangidwa, pomwe ufa wa calcium zinc stabilizers ukhoza kupereka calcium ndi zinc ion zambiri, zomwe zimalepheretsa kusonkhanitsa HCl. Kudzera mu mgwirizano uwu, zinthu zokhazikika za calcium zinc ndi ufa wa organic tin ndi ufa zimatha kuwonjezera kukhazikika kwa kutentha kwa zinthu za PVC, kukonza moyo wawo wautumiki komanso kukhazikika kwa magwiridwe antchito.

Tiyenera kudziwa kuti kuchuluka ndi kuchuluka kwa zinthu zokhazikika za organic tin ndi calcium zinc ziyenera kusinthidwa moyenera malinga ndi zofunikira komanso malo ogwiritsira ntchito zinthu za PVC, kuti zigwirizane bwino. Nthawi yomweyo, ndikofunikira kulabadira nkhani zachitetezo ndi zachilengedwe mukamagwiritsa ntchito kuti mupewe zotsatirapo zoyipa pa thanzi la anthu komanso chilengedwe.
