Itangazamakuru rya PTFEmubisanzwe bivuga itangazamakuru ryakozwe na polytetrafluoroethylene (PTFE mugihe gito). Ibikurikira nintangiriro irambuye kubitangazamakuru bya PTFE:

Ⅰ. Ibikoresho

1.Imitekerereze ihamye

PTFE ni ibikoresho bihamye. Ifite imiti ikomeye kandi irwanya imiti hafi ya yose. Kurugero, mubidukikije bya acide ikomeye (nka acide sulfurike, aside nitric, nibindi), ibishingwe bikomeye (nka sodium hydroxide, nibindi) hamwe nudukoko twinshi kama (nka benzene, toluene, nibindi), ibikoresho bya PTFE ntibizakora muburyo bwa shimi. Ibi bituma ikundwa cyane mubikorwa nka kashe hamwe nu miyoboro iva mu nganda n’imiti n’imiti, kubera ko inganda akenshi zikenera guhangana n’imiti itandukanye igoye.

2. Kurwanya ubushyuhe

Itangazamakuru rya PTFE rishobora gukomeza imikorere yaryo hejuru yubushyuhe. Irashobora gukora mubisanzwe mubushyuhe bwa -200 ℃ kugeza 260 ℃. Ku bushyuhe buke, ntibizacika intege; ku bushyuhe bwinshi, ntabwo izabora cyangwa ngo ihindurwe byoroshye nka plastiki zisanzwe. Uku kurwanya ubushyuhe bwiza butuma itangazamakuru rya PTFE rifite akamaro gakomeye mu kirere, mu buhanga bwa elegitoroniki no mu zindi nzego. Kurugero, muri sisitemu ya hydraulic yindege, itangazamakuru rya PTFE rirashobora kwihanganira ubushyuhe bwo hejuru buterwa nihindagurika ryibidukikije hamwe nibikorwa bya sisitemu mugihe cyo guhaguruka.

3.Korohereza coefficient de coiffure

PTFE ifite coefficente yo hasi cyane, imwe murwego rwo hasi mubikoresho bizwi. Coefficient ya dinamike kandi ihagaze neza ni nto cyane, hafi 0.04. Ibi bituma dielectric ya PTFE ikora neza iyo ikoreshejwe nk'amavuta mu bice bya mashini. Kurugero, mubikoresho bimwe na bimwe byohereza imashini, ibyuma cyangwa ibihuru bikozwe muri PTFE birashobora kugabanya ubushyamirane hagati yimashini, kugabanya ingufu zikoreshwa, no kongera igihe cyibikorwa byibikoresho.

4.Ibikoresho by'amashanyarazi

PTFE ifite ibikoresho byiza byamashanyarazi. Ikomeza kwihanganira cyane kurwego rwo hejuru. Mubikoresho bya elegitoronike, dielectric ya PTFE irashobora gukoreshwa mugukora ibikoresho byokwirinda, nkurugero rwimigozi yinsinga ninsinga. Irashobora gukumira imyanda igezweho, ikemeza imikorere isanzwe yibikoresho bya elegitoroniki, kandi ikanarwanya amashanyarazi aturuka hanze.

Kurugero, mumashanyarazi yihuta yihuta, insinga ya PTFE irashobora kwemeza ituze kandi ryukuri ryohereza ibimenyetso.

5.Kudakomera

Ubuso bwa dielectric ya PTFE bufite imbaraga zidakomera. Ni ukubera ko electronegativite ya atome ya fluor mumiterere ya molekile ya PTFE ari ndende cyane, bigatuma bigora ubuso bwa PTFE guhuza imiti nibindi bintu. Uku kudafatana bituma PTFE ikoreshwa cyane mugutwikira ibikoresho byo guteka (nkibikoresho bidafite inkoni). Iyo ibiryo bitetse mumasafuriya adafite inkoni, ntabwo byoroshye kwizirika kurukuta rwisafuriya, byoroshye gusukura no kugabanya amavuta yakoreshejwe mugihe cyo guteka.
