I-PTFE + MICA IMINERAL IGCWALIWE

I-PTFE (i-PolyTetraFluoroEthylene) iyi-polymer esekwe ku-fluorocarbon futhi eyaziwa kuyo yonke imboni njengegama lomkhiqizo we-Dupont.i-polymer®.Abanye abakhiqizi abaningana benza amabhrendi abo e-PTFE angasetshenziswa kaningi njengento ebambele.Lo mndeni we-fluoroplastic unikeza amapulasitiki anokumelana namakhemikhali aphezulu, amandla okushisa aphansi futhi aphezulu, ukumelana nesimo sezulu, ukungqubuzana okuphansi, ukufakwa kukagesi nokushisa, kanye "nokushelela."

I-PTFE egcwele 5% kuya ku-10% mica inikeza inhlanganisela eyingqayizivele yamandla nokuzinza kobukhulu kanye nobuchwepheshe bokungezwa obugqamayo obugqamile.Lo mkhiqizo uhlinzeka ngokugqoka okuhle kakhulu nokuzinza ngaphezu kokuthobela i-FDA.

I-Fluorosint® ingxube yobunikazi lapho i-mica eyenziwe ngokwenziwa ixhunywe ngamakhemikhali ku-PTFE.Lokhu kubopha kuholela kuzakhiwo ezingafinyeleleki ngokuvamile ku-PTFE eqinisiwe.Amabanga e-Fluorosint® anikeza inhlanganisela enhle kakhulu yezinto ezingqubuzanayo eziphansi, ukuzinza kwe-dimensional, ukumelana namakhemikhali okuhle kakhulu, nezinga lokushisa eliqhubekayo lokusebenzisa elingu-500°F (260°C).Uma kuqhathaniswa ne-PTFE, inamandla okuthwala umthwalo ophakeme, i-1/9 yokuwohloka ngaphansi komthwalo, kanye ne-coefficient ephansi yokwanda okushisayo.

FLUOROSINT AMABANGAI-Fluorosint® 500 inokumelana okuphindwe kasishiyagalolunye ekushintshashintsheni ngaphansi komthwalo kune-PTFE engagcwalisiwe.I-coefficient yayo ye-linear thermal expansion (CLTE) isondela kuzinga lokunwetshwa kwe-aluminium futhi ingu-1/5 leyo ye-PTFE — ivamise ukuqeda izinkinga zokufaneleka nokucaciswa.Ilukhuni ngo-1/3 kune-PTFE, inezici zokuguga ezingcono, futhi igcina izici eziphansi zokungqubuzana.I-Fluorosint ® 500 nayo ayibiki ezintweni eziningi zokukhwelana.

Ukuzinza kobukhulu obungenakuqhathaniswa kwe-Fluorosint® 207, ukumelana okuhle kakhulu nokukhasa kanye nombala omhlophe kubeka lesi sici ngendlela ehlukile ukuze kusetshenziswe izinhlelo zokusebenza ezilawulwa yi-FDA.Ayingeneki kusitimu futhi ithobela umthetho we-FDA 21 CFR 175.300.Izinga lokuguga elihlobene lingu-1/20 izinga le-PTFE elingaphansi kuka-300°F (150°C).Inhlanganisela yokusebenza kahle komshini kanye nokumelana kwayo okuvelele kwamakhemikhali kanye ne-hydrolysis, i-Fluorosint® 207 ivula amathuba amaningi okusebenza ezimbonini zokudla, ezemithi, nezokwelapha.
