Litšobotsi le Matlotlo a Li-Stabilizer tsa Potassium-Zinc
Li-stabilizer tsa potassium-zinc, tse tsejoang hape e leLi-stabilizer tsa K-Zn, ke motsoako o kopanetsoeng oa metsoako ea potassium le zinki e etselitsoeng ho ntlafatsa botsitso ba mocheso oa PVC. Li-stabilizer tsena li nka sebaka sa li-stabilizer tse thehiloeng ho loto ka katleho, tse seng li felisitsoe haholo ka lebaka la matšoenyeho a tikoloho le bophelo bo botle.li-stabilizer tsa potassium-zince kenyelletsa botsitso bo botle ba mocheso, ponaletso e ntlafetseng, le ho lumellana ho ntlafetseng le mefuta e fapaneng ea PVC.
*Botsitso ba Thermal:Li-stabilizer tsa potassium-zinc li sebetsa hantle haholo ho thibeleng ho senyeha ha PVC mochesong o phahameng. Nakong ea ts'ebetso ea letlalo la maiketsetso la PVC, thepa e kenngoa mochesong o moholo, e leng se ka etsang hore liketane tsa polymer li robehe, e leng se lebisang ho fifaleng ha 'mala, tahlehelo ea thepa ea 'mele, le ho lokolloa ha hydrochloric acid (HCl). Li-stabilizer tsa potassium-zinc li thusa ho boloka botšepehi ba ketane ea polymer ea PVC, ho netefatsa hore thepa e boloka thepa ea eona leha e pepesehetse mocheso nako e telele.
*Ponaletso le ho Tšoara 'Mala:Li-stabilizer tsena li kenya letsoho tlhahisong ea lihlahisoa tsa PVC tse hlakileng le tse khanyang. Li thibela ho ba mosehla le ho fifala ha 'mala ho hong, li netefatsa hore lihlahisoa tsa ho qetela tsa letlalo la maiketsetso li boloka botle ba tsona bo khahlehang. Sena se bohlokoa haholo indastering ea feshene le ea likoloi, moo ponahalo ea letlalo la maiketsetso e leng ntlha ea bohlokoa ea boleng.
*Tšireletso ea Tikoloho:E 'ngoe ea melemo ea bohlokoa ea li-stabilizer tsa potassium-zinc ke botsoalle ba tsona tikolohong. Ho fapana le li-stabilizer tse thehiloeng ho loto, li-stabilizer tsa potassium-zinc ha li ntše lintho tse chefo nakong ea ts'ebetso kapa ho lahla. Sena se li etsa khetho e sireletsehileng bakeng sa bahlahisi le basebelisi ba ho qetela, e tsamaellanang le tlhoko e ntseng e hola ea thepa e tsitsitseng le e seng chefo liindastering tse fapaneng.
Mekhoa ea Kopo
Ho kopanngoa ha li-stabilizer tsa potassium-zinc ka har'a metsoako ea PVC ho kenyelletsa mehato e 'maloa, hangata e etsahalang nakong ea mohato oa ho kopanya. Li-stabilizer tsena li ka kenyelletsoa ka mekhoa e fapaneng, ho kenyeletsoa ho kopanya ka omileng, ho ntša le ho enta ka ente.
1. Ho Kopanya ka Omileng:Motswakong o omileng, di-stabilizer tsa potassium-zinc di kopanngwa le resin ya PVC le di-additives tse ding ka hara motswako o potlakileng. Motswako ona o bewa maemong a mocheso o phahameng le matla a ho kgaola ho netefatsa kabo e tshwanang ya di-stabilizer ho pholletsa le matrix ya PVC. Ts'ebetso ena e bohlokwa bakeng sa ho fihlella botsitso bo tsitsitseng ho pholletsa le sehlopha sohle sa thepa ya PVC.
2. Ho ntša:Nakong ea ho ntša metsi, motsoako oa PVC o kopantsoeng ka ommeng o fepuoa ka har'a sesebelisoa sa ho ntša metsi, moo se qhibilihang le ho etsoa hore se be homogeneous. Li-stabilizer li netefatsa hore thepa ea PVC e lula e tsitsitse 'me ha e senyehe tlas'a mocheso o phahameng le likhatello tse amehang ho ntša metsi. PVC e ntšoang e etsoa maqephe kapa lifilimi, tseo hamorao li sebelisoang tlhahisong ea letlalo la maiketsetso.
3. Ho Enta ka Ente:Bakeng sa lits'ebetso tse hlokang libopeho le meralo e qaqileng, ho sebelisoa ho bōptjoa ka ente. Motsoako oa PVC, o nang le li-stabilizer tsa potassium-zinc, o kenngoa ka har'a mokoti oa hlobo moo o pholang le ho tiea ho ba sebopeho se lakatsehang. Li-stabilizer li bapala karolo ea bohlokoa ho bolokeng botsitso ba mocheso nakong ea ts'ebetso ena, ho thibela liphoso sehlahisoa sa ho qetela.
Hobaneng ha Li-Stabilizer tsa Potassium-Zinc li Bitsoa "Li-Kickers"
Poleloana "kicker" moelelong oa li-stabilizer tsa potassium-zinc e simoloha bokhoning ba tsona ba ho potlakisa ts'ebetso ea gelation ea li-plastisol tsa PVC nakong ea ho futhumatsa. Tlhahisong ea letlalo la maiketsetso la PVC, ho fihlella gelation e lakatsehang le ho kopanngoa ha plastisol ea PVC ho bohlokoa haholo. Li-stabilizer tsa Potassium-zinc li sebetsa e le li-kicker ka ho fokotsa matla a ts'ebetso a hlokahalang bakeng sa gelation, ka hona li potlakisa ts'ebetso eohle. Gelation ena e potlakileng e molemo hobane e lebisa lipotolohong tse potlakileng tsa tlhahiso le lits'ebetso tse sebetsang hantle tsa tlhahiso.
Melemo le Tshebetso
Li-stabilizer tsa potassium-zinc li fana ka melemo e 'maloa ea ts'ebetso tlhahisong ea letlalo la maiketsetso la PVC. Tsena li kenyelletsa:
*Botsitso bo Ntlafalitsoeng ba Thermal:Li-stabilizer tsena li fana ka botsitso bo phahameng ba mocheso ha li bapisoa le li-stabilizer tsa setso, li netefatsa hore thepa ea PVC e ka mamella mocheso o phahameng oa ts'ebetso ntle le ho senyeha. Sena se bohlokoa haholo indastering ea letlalo la maiketsetso, moo maqephe le lifilimi tsa PVC li futhumatsoang nakong ea lits'ebetso tse kang ho khabisa le ho laminating.
*Boleng bo Ntlafetseng ba Sehlahisoa:Ka ho thibela ho senyeha le ho fifala ha 'mala, li-stabilizer tsa potassium-zinc li thusa ho hlahisa letlalo la maiketsetso la boleng bo holimo la PVC le nang le liphoso tse fokolang. Sena se lebisa sehlahisoa se tsitsitseng le se tšepahalang haholoanyane, e leng sa bohlokoa bakeng sa ho fihlela maemo a indasteri le litebello tsa bareki.
*Ho Latela Tikoloho:Tšebeliso ea li-stabilizer tsa potassium-zinc e tsamaisana le litlhoko tse ntseng li eketseha tsa taolo le tsa bareki bakeng sa thepa e sireletsang tikoloho. Li-stabilizer tsena ha li lokolle lintho tse kotsi, e leng se etsang hore ts'ebetso ea tlhahiso e be e sireletsehileng le e tsitsitseng haholoanyane.
*Bokgoni ba ho Sebetsa:Tšebeliso ea li-stabilizer tsa potassium-zinc e ka ntlafatsa katleho ea ts'ebetso ka ho fokotsa monyetla oa liphoso tse kang li-fisheye, li-gel le matheba a matšo. Sena se fella ka chai e phahameng le litšenyehelo tse tlase tsa tlhahiso, e leng se tlatsetsang katlehong ea moruo ka kakaretso ea ts'ebetso ea tlhahiso.
Tšebeliso ea li-stabilizer tsa potassium-zinc hoLetlalo la maiketsetso la PVCIndasteri e emela tsoelo-pele e kholo theknolojing ea ho tsitsisa thepa. Li-stabilizer tsena li fana ka botsitso bo hlokahalang ba mocheso, ponaletso le polokeho ea tikoloho e hlokahalang bakeng sa ho hlahisa lihlahisoa tsa letlalo la maiketsetso tsa boleng bo holimo. Ha indasteri e ntse e tsoela pele ho beha pele botsitso le polokeho, li-stabilizer tsa potassium-zinc li ikemiselitse ho bapala karolo ea bohlokoa haholoanyane nakong e tlang ea tlhahiso ea letlalo la maiketsetso la PVC.
