Uburyo bundi bwo gukemura PPA mu gihe habayeho inzitizi za PFAS

PPA (Polymer Processing Additive) ni igikoresho gifasha gutunganya fluoropolymer, ni imiterere ya polymer ishingiye kuri fluoropolymer, kugira ngo inoze imikorere ya polymer, ikureho gushonga kw'ibintu bishongeshejwe, ikemure ubwinshi bw'ibice, inoze sharkskin, nibindi. Yavumbuwe bwa mbere na DuPont mu 1961 ishyirwa ku isoko mu myaka ya za 80, hanyuma itangizwa na sosiyete ya 3M kugira ngo yongere kohereza mu mahanga fluorine elastomer PPA…… Bitewe n'iterambere rikomeje ry'ikoranabuhanga, ibikoresho bifasha gutunganya PPA fluorine birakoreshwa cyane kandi buhoro buhoro bifata umwanya ukomeye mu gutunganya filime, imiyoboro, imiyoboro, insinga, n'ibindi.

Icyifuzo cyo kugabanya PFAS (Perfluoro na Polyfluoroalkyl Substances), cyateguwe n'abayobozi ba Danemark, Ubudage, Finlande, Noruveje na Suwede, cyashyikirijwe ECHA ku ya 13 Mutarama 2023, hagamijwe kugabanya irekurwa rya PFAS mu bidukikije no gutuma ibicuruzwa n'imikorere birushaho kuba byiza binyuze mu guhagarika Perfluoroalkyl Substances (PFAS) na Polyfluoroalkyl Substances (PFAS) birimo nibura atome imwe ya karuboni ivanze na perfluorine (igereranywa ko ari molekile 10.000 muri rusange), harimo na fluoropolymers zizwi cyane. (PFAS), harimo na fluoropolymers zizwi cyane. Ibihugu bigize umuryango bizatora itegeko ryo guhagarika muri 2025. Icyifuzo cy'i Burayi, nigihinduka, kizahagarika ikoreshwa rya fluoropolymers zisanzwe nka PTFE na PVDF, bikabuza ikoreshwa ryinshi usibye bike nk'ibikoresho byo kwa muganga, ibikoresho byo gukorana n'ibiribwa, uturemangingo twa lisansi, nibindi, kandi bigira ingaruka zikomeye ku bidukikije by'inganda zose.

Mu gusubiza, SILIKE yashyizeho uburyo bwoubundi buryo budafite fluorinekuri PPA ishingiye kuri Fluorine ——aIbikoresho byo gutunganya polimeri bidafite PFAS (PPAS)IbiPPA MB idafite fluorine, Inyongeramusaruro idafite PTFE ni polysiloxane masterbatch yahinduwe mu buryo bw'umwimerere ikoresha ingaruka nziza zo gusiga amavuta ya polysiloxane ndetse n'uburyo amatsinda yahinduwe yimuka kandi agakora ku bikoresho bitunganywa mu gihe cyo gutunganya, bigatuma habaho imikorere imwe n'inyongeramusaruro irimo silikoni idafite fluorine mu gusohora insinga n'insinga, imiyoboro, na firime, kandi ingano nto y'iyi nyongeramusaruro irushaho kunoza uburyo resin itembera n'uburyo itunganywa, ndetse no gusiga amavuta n'imiterere y'ubuso bwa pulasitiki iri gusohoka. Kongeramo ingano nto bishobora kunoza uburyo resin itembera, uburyo itunganywa, uburyo itunganywa, n'imiterere y'ubuso mu gihe cyo gusohora pulasitiki, bikagirira akamaro abakiriya ba polymer n'isi mu gihe byongera umusaruro n'ubwiza bw'ibicuruzwa.

PPA MB idafite Fluorine ya SILIKE, PPA idafite PFAS, naNta PTFEInyongeramusaruro zishobora gusimbura masterbatch ya fluorine PPA, Inyongeramusaruro ya PFAS Polymer, PPA MB, ibicuruzwa bya PPA, fluoropolymer, PPAs zishingiye kuri fluorine, mu nganda nyinshi nka filime za pulasitiki, insinga n'imiyoboro, imiyoboro…nibindi.

Ibitaramo bisanzwe:

Kunoza uburyo bwo gutunganya pulasitiki no gukoresha neza ikoranabuhanga mu kuyisohora;

Kugabanya imbaraga n'ubusaza bw'ibikoresho;

Gabanya amatembabuzi y'uruhu rw'ifi kandi wongere imiterere y'uruhu rw'ifi.
