Liquid Barium Zinc PVC Stabilizersndi zowonjezera zapadera zomwe zimagwiritsidwa ntchito popanga polyvinyl chloride (PVC) kuti zithandizire kukhazikika kwamafuta ndi kuwala, kupewa kuwonongeka panthawi yopanga ndikukulitsa moyo wazinthuzo. Nawa tsatanetsatane wa kapangidwe kawo, kagwiritsidwe, kaganizidwe kawo, ndi momwe msika ukuyendera:
Kupanga ndi Mechanism
Ma stabilizers awa nthawi zambiri amakhala ndi mchere wa barium (mwachitsanzo, alkylphenol barium kapena 2-ethylhexanoate barium) ndi mchere wa zinki (mwachitsanzo, 2-ethylhexanoate zinc), kuphatikiza zigawo za synergistic monga phosphites (mwachitsanzo, tris(nonylphenyl) phosphite) wamafuta a chelation, mchere ndi zosungunulira. Barium imapereka chitetezo chanthawi yayitali, pomwe zinc imapereka kukhazikika kwanthawi yayitali. Mawonekedwe amadzimadzi amatsimikizira kusakanikirana kofanana mu mapangidwe a PVC. Mapangidwe aposachedwa amaphatikizanso ma polyether silicone phosphate esters kuti apititse patsogolo mafuta komanso kuwonekera, kuchepetsa kuyamwa kwamadzi panthawi yozizira.
Ubwino waukulu
Zopanda Poizoni: Zopanda zitsulo zolemera monga cadmium, zimayenderana ndi zakudya komanso zachipatala (monga magiredi ovomerezedwa ndi FDA m'mapangidwe ena).
Processing Mwachangu: Dziko lamadzimadzi limatsimikizira kubalalitsidwa kosavuta muzinthu zofewa za PVC (mwachitsanzo, mafilimu, mawaya), kuchepetsa nthawi yokonza ndikugwiritsa ntchito mphamvu.
Mtengo-Kuchita bwino: Kupikisana ndi organic tin stabilizers popewa nkhawa za kawopsedwe.
Zotsatira za Synergistic: Akaphatikizidwa ndi calcium-zinc stabilizers, amathetsa nkhani za "tonguing" mu olimba PVC extrusion mwa kugwirizanitsa lubricity ndi kukhazikika kwa kutentha.
Mapulogalamu
Zofewa za PVC: Amagwiritsidwa ntchito kwambiri m'mafilimu osinthika, zingwe, zikopa zopanga, ndi zida zamankhwala chifukwa chosakhala ndi poizoni komanso kusungidwa bwino.
Zithunzi za PVC: Kuphatikiza ndicalcium-zinc stabilizers, amapangitsa kuti mafilimu ndi mbiri zitheke, kuchepetsa "kulankhula" (kutsetsereka kwa zinthu panthawi ya extrusion).
Specialty Applications: Zopangira zowoneka bwino kwambiri zopakira ndi zinthu zolimbana ndi UV zikaphatikizidwa ndi ma antioxidants ngati 2,6-di-tert-butyl-p-cresol.
Malingaliro Oyang'anira ndi Zachilengedwe
Fikirani Kutsatira: Mankhwala a Barium amayendetsedwa pansi pa REACH, ndi zoletsa pa barium yosungunuka (mwachitsanzo, ≤1000 ppm muzinthu za ogula). Zambiri zamadzimadzi barium zinki stabilizers zimakwaniritsa malire awa chifukwa cha kusungunuka kochepa.
Njira zina: Ma Calcium-zinc stabilizers ayamba kuyenda bwino chifukwa cha malamulo okhwima a chilengedwe, makamaka ku Europe. Komabe, ma barium zinc stabilizers amakhalabe okondedwa pamagwiritsidwe ntchito otentha kwambiri (mwachitsanzo, mbali zamagalimoto) komwe calcium-zinc yokha ingakhale yosakwanira.
Ntchito ndi Technical Data
Kutentha Kukhazikika: Kuyesa kwa kutentha kosasunthika kumawonetsa kukhazikika kotalikirapo (mwachitsanzo, mphindi 61.2 pa 180 ° C pakupanga ndi hydrotalcite co-stabilizers) . Kusintha kwamphamvu (mwachitsanzo, ma twin-screw extrusion) amapindula ndi mafuta awo, amachepetsa kumeta ubweya.
Kuwonekera: Mapangidwe apamwamba kwambiri okhala ndi polyether silicone esters amakwaniritsa kumveka bwino kwambiri (≥90% transmittance), kuwapanga kukhala oyenera kulongedza mafilimu.
Kusamukasamuka: Zokhazikitsira zokonzedwa bwino zimawonetsa kusamuka kocheperako, kofunikira kwambiri pamapulogalamu monga kuyika chakudya komwe kuli nkhawa.
Malangizo Othandizira
KugwirizanaPewani kugwiritsa ntchito kwambiri mafuta a stearic acid, chifukwa amatha kuchitapo kanthu ndi mchere wa zinki, zomwe zimathandizira kuwonongeka kwa PVC. Sankhanico-stabilizersmonga epoxidized soya mafuta kuti azigwirizana.
Mlingo: Kugwiritsiridwa ntchito kwachizoloŵezi kumachokera ku 1.5-3 phr (gawo pa zana la resin) mu PVC yofewa ndi 0.5-2 phr muzitsulo zolimba pamene zikuphatikizidwa ndi calcium-zinc stabilizers.
Zochitika Zamsika
Madalaivala a Kukula: Kufunika kwa zolimbitsa thupi zopanda poizoni ku Asia-Pacific ndi North America kukukankhira zatsopano pakupanga barium zinc. Mwachitsanzo, makampani a PVC aku China akuchulukirachulukira kugwiritsa ntchito zolimbitsa thupi za barium zinki popanga mawaya/zingwe.
Zovuta: Kuwonjezeka kwa calcium-zinc stabilizers (yoyembekezeredwa CAGR ya 5-7% muzovala za nsapato ndi chigawo cholongedza) kumabweretsa mpikisano, koma barium zinc imasunga niche yake muzogwiritsira ntchito kwambiri.
Liquid Barium Zinc PVC Stabilizers amapereka ndalama zogwirira ntchito, kukhazikika kwamafuta, komanso kutsata malamulo, kuwapangitsa kukhala ofunikira kwambiri pazinthu zofewa komanso zolimba za PVC. Ngakhale kupsinjika kwa chilengedwe kumapangitsa kusintha kwa njira zina za calcium-zinc, mawonekedwe awo apadera amatsimikizira kufunikira kwamisika yapadera. Opanga amayenera kulinganiza mosamalitsa zofunikira pakuchita bwino ndi malangizo owongolera kuti apindule kwambiri.
