Li-sieve tsa molek'hule tsa Zeolite li hohetse tlhokomelo e kholo lilemong tsa morao tjena e le li-stabilizers indastering ea polasetiki, joalo ka polyvinyl chloride (PVC) le polypropylene (PP). Ka tloaelo li sebelisetsoa ho thibela maikutlo a ho senyeha le ho matlafatsa botsitso ba mocheso, kahoo ho lelefatsa bophelo ba tšebeletso.
PVC Zeolite Stabilizer
PVC e na le kutloelo-bohloko ho mocheso, ho se tsitse ha mocheso o fokolang, 'me e na le tšekamelo ea ho senyeha ha mocheso o phahameng. Li-stabilizer tsa mocheso lia hlokahala ho thibela ho bola, ho fifala, le tahlehelo ea thepa ea mochini ea thepa ea PVC.
PVC e ntša hydrogen chloride ha e pepesehile mocheso, e leng eona ntho e tobileng e etsang hore PVC e fifale ka 'mala le ho senyeha mosebetsing. Kahoo li-stabilizers tsa mocheso li ikarabella bakeng sa ho se nke lehlakore ha hydrogen chloride le ho thibela ho senyeha ha ketane.
Li-sieve tsa molek'hule tsa Zeolite li na le bokhoni ba ho adsorb hydrogen chloride, 'me li ka boela tsa sebetsa hammoho le calcium kapa zinc stabilizers ho matlafatsa botsitso ba mocheso oa PVC, le ho ntlafatsa ho fifala ha pele le mathata a nako e telele{0}a botsofali a PVC.
PP Zeolite Stabilizer
PP e ka hlaseloa habonolo ke oxidation, ho phatloha ha mocheso, kapa ho senyeha ha lifoto, kahoo e hloka ho eketsoa ha li-antioxidants le li-stabilizers tsa mocheso. Haholo-holo ka li-masterbatches tse tlatsitsoeng le lisebelisoa tse tsosolositsoeng, litšila (metsi, li-acids) li tla potlakisa ts'ebetso ea ho senyeha.
Li-sieve tsa limolek'hule tsa Zeolite li monya metsi a setseng ka har'a sistimi ea PP ho ntlafatsa botsitso ba ts'ebetso, ho monya litšila tse nang le acidic joalo ka peroxides le organic acid ho ntlafatsa thepa ea antioxidant, hape e ka sebetsa ka synergy le li-additives tse ling ho thibela phetisetso ea mocheso le oksijene, ka ho lelefatsa bophelo ba ts'ebeletso ea PP.
Joalo ka li-stabilizer tsa PP kapa li-filler tsa PP composite, li-sieve tsa limolek'hule ha li falle kapa ha li fetohe, li na le botsitso bo botle ba mocheso, 'me li ka tsoakoa le li-inorganic fillers kapa li-additives ho ntlafatsa ts'ebetso ea lisebelisoa tsa PP.
Zeolite Molecular Sieves Bakeng sa PVC / PP Stabilizers
Li-sieve tsa molek'hule tsa Zeolite tse ka sebelisoang bakeng sa li-stabilizers tsa PVC/PP li kenyelletsa mofuta oa A, P, X le Y. Leha ho le joalo, mofuta oa A molecular sieve (mohlala. 4A zeolite powder) o loketse haholoanyane ka lebaka la ts'ebeliso ea oona le litšenyehelo{3}}ka katleho.
Mofuta oa 3A zeolite molecular sieve: E atisa ho sebelisoa e le li-desiccants ho monya mongobo tsamaisong ea PVC kapa PP. E boetse e na le phello e itseng ea ho hapa li-acids tse sa lefelloeng (tse kang trace acid e hlahisoang ke ho senyeha ha oxidative) tsamaisong ea PP.
Mofuta oa 4A zeolite molecular sieve: Ho li-stabilizers tsa PVC, e monya limolek'hule tse nyane tsa hydrogen chloride, ho thibela karabelo ea ho senyeha le ho ntlafatsa ho fifala ha mocheso. Ho li-stabilizers tsa PP, e monya litšila tsa mongobo le acidic, e ntlafatsa botsitso ba ts'ebetso le ho fokotsa litekanyetso tsa ho senyeha.
Mofuta oa 5A zeolite molecular sieve: E monya hydrogen chloride le limolek'hule tsa litšila tse lokolloang nakong ea ts'ebetso ea PVC, 'me e sebelisoa haholo-holo ho ntlafatsa bokhoni ba adsorption le ho hanyetsa mocheso.
Mofuta oa 13X zeolite molecular sieve: E na le matla a mangata a adsorption mme e khona ho monya hydrogen chloride, sulfur dioxide, le likhase tse ling tsa asiti. Ka kakaretso e sebelisoa lits'ebetsong tse ikhethileng tsa PVC kapa joalo ka sejari sa composite stabilizer.
