Mphamvu ya synergistic ya organic tini ndi ufa calcium zinc stabilizers mu polyvinyl chloride (PVC)

Mphamvu ya synergistic ya organic tini ndi ufa calcium zinc stabilizers mu polyvinyl chloride (PVC):

Organic tin stabilizers (thiol methyl tin) ndi mtundu womwe umagwiritsidwa ntchito kwambiri wa PVC heat stabilizer. Amachita ndi acidic hydrogen chloride (HCl) mu PVC kupanga mchere wopanda vuto (monga tini chloride), potero amalepheretsa kudzikundikira kwa HCl ndikuchepetsa kuwonongeka ndi chikasu kwa zida za PVC.

Powder calcium zinc stabilizer ndi osakaniza a calcium ndi mchere wa zinki, nthawi zambiri amawonjezedwa ngati ufa wabwino ku PVC. Ma ions onse a calcium ndi zinc amatha kukhazikika PVC. Maoni a calcium amatha kusokoneza zinthu za acidic zomwe zimapangidwa mu PVC ndikupanga mchere wokhazikika wa calcium. Ma ions a zinki amachitira ndi hydrogen peroxide (HCl) mu PVC kupanga mankhwala osavulaza osavulaza ndikuletsa kuchuluka kwa HCl.

Pamene organic tini ndi ufa calcium zinc stabilizers amakhala pamodzi mu PVC, iwo akhoza kulimbikitsana wina ndi mzake ndi kusintha luso kuchitira HCl. Tini ya organic ingapereke mphamvu yowonjezereka yochepetsera HCl yochuluka yopangidwa, pamene ufa wa calcium zinc stabilizers ungapereke ma ion a calcium ndi zinc, kulepheretsanso kudzikundikira kwa HCl. Kupyolera mu izi synergistic zotsatira, organic malata ndi ufa calcium zinki stabilizers angathe kupititsa patsogolo bata la zipangizo PVC, kusintha moyo wawo utumiki ndi bata.

Dziwani kuti kuchuluka ndi kuchuluka kwa organic malata ndi calcium zinc stabilizers ziyenera kusinthidwa molingana ndi zofunikira zenizeni komanso malo ogwiritsira ntchito mankhwala a PVC, kuti akwaniritse zotsatira zabwino kwambiri za synergistic. Panthawi imodzimodziyo, m'pofunika kusamala za chitetezo ndi chilengedwe pakugwiritsa ntchito kuti tipewe zotsatira zoipa pa thanzi laumunthu ndi chilengedwe.
