Setsibi sa Barium-zinkike mofuta oa sehatsetsi se sebelisoang haholo indastering ea polasetiki, se ka ntlafatsang botsitso ba mocheso le botsitso ba UV ba lisebelisoa tse fapaneng tsa polasetiki. Lihatsetsi tsena li tsebahala ka bokhoni ba tsona ba ho thibela thepa ea polasetiki hore e se ke ea senyeha, e leng se etsang hore e be tse loketseng lits'ebetso tsa kantle le tikoloho ea mocheso o phahameng. Sehloohong sena, re tla hlahloba ts'ebeliso le melemo ea lihatsetsi tsa zinki tsa barium indastering ea polasetiki.
Li-stabilizer tsa Barium-zinc li sebelisoa haholo tlhahisong ea PVC (polyvinyl chloride) le thepa e 'ngoe ea polasetiki. PVC ke polymer ea thermoplastic e sebelisoang haholo e sebelisoang lits'ebetsong tse fapaneng, ho kenyeletsoa indasteri ea kaho, ea liphutheloana le ea likoloi. Leha ho le joalo, hoa tsebahala hore PVC e kotsing ea ho senyeha ha e pepesetsoa mocheso le mahlaseli a UV, e leng se lebisang liphetohong tsa thepa ea eona ea mechini le ea 'mele. Mona ke moo li-stabilizer tsa barium zinc li kenang teng.
Morero o ka sehloohong oa ho sebelisa li-stabilizer tsa barium zinc ho PVC le thepa e 'ngoe ea polasetiki ke ho thibela ho senyeha ka lebaka la mocheso le ho pepesehela mahlaseli a kotsi a UV. Karolo ea li-stabilizer tsena ke ho tlosa li-free radical tse hlahisoang nakong ea ho senyeha, ka hona ho thibela liketso tsa ketane tse lebisang ho robeheng ha liketane tsa polymer. Ka lebaka leo, thepa ea polasetiki e lula e tsitsitse 'me e boloka thepa ea eona leha e pepesehetse maemo a thata a tikoloho.
E 'ngoe ea melemo e meholo ea ho sebelisa li-stabilizer tsa barium zinc ke botsitso ba tsona bo botle ba mocheso. Sena se etsa hore li lokele haholo-holo lits'ebetsong moo thepa ea polasetiki e pepesetsoang mocheso o phahameng, joalo ka thepa ea kaho, likarolo tsa likoloi le terata ea motlakase. Ho phaella moo, li-stabilizer tsa barium-zinc li na le khanyetso e ntle ea UV, e leng se etsang hore li be ntle bakeng sa lits'ebetso tsa kantle moo thepa ea polasetiki e pepesetsoang ke khanya ea letsatsi.
Ntle le botsitso ba mocheso le UV, li-stabilizer tsa barium zinc li fana ka melemo e meng. Li theko e tlase ebile li sebetsa hantle, li hloka litekanyo tse tlase ha li bapisoa le mefuta e meng ea li-stabilizer. Sena se bolela hore bahlahisi ba hloka feela ho sebelisa bonyane ba stabilizer ho fihlela boemo bo lakatsehang ba botsitso, ho boloka litšenyehelo le ho ntlafatsa ts'ebetso eohle ea sehlahisoa.
Ho phaella moo, di-stabilizer tsa barium-zinc di tsebahala ka ho tsamaellana ha tsona le mefuta e mengata ya di-additives le maemo a tshebetso. Sena se etsa hore di be bonolo ho di kopanya le mekgwa ya tlhahiso, e leng se etsang hore ho be bonolo ho di kopanya le ho di etsa, e leng se etsang hore ho be bonolo ho di sebedisa tlhahisong ya thepa ya polasetiki. Di-stabilizer tsena tse feto-fetohang le ho tsamaellana di etsa hore di-stabilizer tsa barium zinc e be kgetho e tsebahalang bakeng sa bahlahisi ba bangata ba polasetiki.
Hape ho bohlokoa ho hlokomela hore li-stabilizer tsa barium-zinc li nkoa li le mosa tikolohong ha li bapisoa le mefuta e meng ea li-stabilizer, joalo ka li-stabilizer tse thehiloeng ho loto. Ha temoho ea litaba tsa tikoloho le melaoana e ntse e eketseha, li-stabilizer tsa barium-zinc li se li atile haholo e le khetho e tsitsitseng le e mosa tikolohong bakeng sa ho tsitsisa thepa ea polasetiki.
Li-stabilizer tsa Barium-zinc li sebelisoa haholo indastering ea polasetiki ka lebaka la bokhoni ba tsona ba ho ntlafatsa botsitso ba mocheso le UV, ho thibela ho senyeha, le ho boloka thepa ea thepa ea polasetiki. Tshebetso ea eona e phahameng, ho boloka litšenyehelo hantle le botsoalle ba tikoloho li etsa hore e be khetho e tsebahalang bakeng sa lits'ebetso moo botsitso le ho tšoarella li leng bohlokoa. Ha tlhoko ea thepa ea polasetiki e sebetsang hantle e ntse e hola, li-stabilizer tsa barium-zinc li lebelletsoe ho bapala karolo ea bohlokoa ho fihlelleng litlhoko tsena ha li ntse li fihlela maemo a botsitso le a taolo.
