Zeolite molecular sieves adọtala nlebara anya dị ukwuu n'afọ ndị na-adịbeghị anya dị ka ndị na-emezi ihe na ụlọ ọrụ plastik, dị ka polyvinyl chloride (PVC) na polypropylene (PP). A na-ejikarị ha egbochi mmeghachi omume mmebi ma kwalite nkwụsi ike nke okpomọkụ, si otú ahụ gbasaa ndụ ọrụ.
PVC Zeolite Stabilizer
PVC na-enwe mmetụta na-ekpo ọkụ na-ekpo ọkụ, nke na-adịghị mma na-ekpo ọkụ na-adịghị mma, na-enwekwa ike imebi na okpomọkụ dị elu. A na-achọ ihe ndị na-ekpo ọkụ ọkụ iji gbochie ire ere, mwepu agba, na mfu ihe onwunwe PVC.
PVC na-ahapụ hydrogen chloride mgbe ekpughere ya na okpomọkụ, nke bụ kpọmkwem ihe na-eme ka PVC gbaa ọchịchịrị na agba na njọ na arụmọrụ. Ya mere, ndị na-ahụ maka ikpo ọkụ na-ahụ maka nnọpụiche nke hydrogen chloride na mgbochi nke mmebi agbụ.
Zeolite molecular sieves nwere ike ịgbasa hydrogen chloride, ma nwekwara ike ịrụ ọrụ na mmekọrịta ya na calcium ma ọ bụ zinc stabilizers iji kwalite nkwụsi ike nke ọkụ PVC zuru ezu, ma melite ngbanwe mbụ na ogologo oge {{0} nsogbu ịka nká nke PVC.
PP Zeolite Stabilizer
PP dị mfe na oxidation, thermal cracking, or photodegradation, ma si otú a na-achọ mgbakwunye nke antioxidants na okpomọkụ stabilizers. Karịsịa na masterbatches jupụtara na ihe eji emegharịgharị, adịghị ọcha (mmiri, acids) ga-eme ka usoro mmebi ahụ dịkwuo ngwa.
Zeolite molecular sieves na-etinye mmiri fọdụrụnụ na usoro PP iji meziwanye nkwụsi ike nhazi, na-etinye ihe ndị na-adịghị ọcha acidic dị ka peroxides na organic acids iji welie ihe ndị na-emepụta antioxidant, ma nwee ike ịrụ ọrụ na synergy na ihe mgbakwunye ndị ọzọ iji gbochie nnyefe nke okpomọkụ na oxygen, si otú ahụ na-agbatị ndụ ọrụ nke PP.
Dị ka PP stabilizers ma ọ bụ fillers nke PP composite, molekụla sieves adịghị akwaga ma ọ bụ na-agbanwe agbanwe, na-enwe ezigbo nkwụsi ike nke okpomọkụ, ma nwee ike jikọta ya na ihe ndị na-emepụta ihe ma ọ bụ ihe mgbakwunye iji meziwanye arụmọrụ nke ihe PP.
Zeolite Molecular Sieves Maka PVC/PP Stabilizers
Zeolite molecular sieves nke enwere ike iji maka PVC/PP stabilizers gụnyere ụdị A, P, X na Y. Otú ọ dị, ụdị A molecular sieve (dịka . 4A zeolite ntụ ntụ) dabara nke ọma n'ihi iji mmetụta na ọnụ ahịa ya- arụmọrụ.
Ụdị 3A zeolite molecular sieve: A na-ejikarị ya eme ihe dị ka ndị na-edozi mmiri iji nweta mmiri na PVC ma ọ bụ PP usoro. Ọ na-enwekwa mmetụta ụfọdụ n'ịweta acids efu (dị ka acids trace acid na-emepụta site na mmebi oxidative) na sistemụ PP.
Ụdị 4A zeolite molecular sieve: Na PVC stabilizers, ọ na-amịkọrọ obere ụmụ irighiri mmiri nke hydrogen chloride, na-egbochi mmeghachi omume mmebi na imeziwanye mgbanwe okpomọkụ. Na PP stabilizers, ọ na-amịkọrọ mmiri na adịghị ọcha acidic, na-eme ka nkwụsi ike nhazi na ibelata ọnụego mmebi.
Ụdị 5A zeolite molecular sieve: Ọ na-amịkọrọ hydrogen chloride na ụmụ irighiri ihe na-adịghị ọcha ewepụtara n'oge nhazi PVC, a na-ejikwa ya eme ihe iji melite ikike adsorption na nguzogide okpomọkụ.
Ụdị 13X zeolite molecular sieve: Ọ nwere ikike mgbasa ozi ka ukwuu ma nwee ike ịmịkọrọ hydrogen chloride, sulfur dioxide, na gas acidic ndị ọzọ. A na-ejikarị ya na sistemu mgbakwunye PVC akọwapụtara ma ọ bụ dị ka onye na-ebu stabilizer mejupụtara.
