Imyenda ya PTFE, cyangwa polytetrafluoroethylene, ni imyenda ikora cyane ikora cyane mumirima myinshi kubera amazi meza cyane, adahumeka, yumuyaga, hamwe nubushyuhe.
Intangiriro yimyenda ya PTFE ni firime ya polytetrafluoroethylene ya microporome, ifite imiterere yihariye ya microporome ifite pore ingana na microni 0.1-0.5 gusa, ikaba ari nto cyane ugereranije na diameter ya molekile y'amazi, ariko inshuro ibihumbi n'ibihumbi kuruta molekile y'amazi y'amazi. Kubwibyo, imyenda ya PTFE irashobora guhagarika neza kwinjira mubitonyanga byamazi mugihe ituma imyuka yamazi itembera mubwisanzure, bikageraho bihujwe neza bitarimo amazi kandi bihumeka. Iyi myenda kandi ifite imiterere myiza yumuyaga, kandi imiterere ya microporome irashobora gukumira neza ikirere, bityo bikagumana ubushyuhe imbere yumwenda.
1. Ibintu shingiro bya PTFE
PTFE yatunganijwe bwa mbere na DuPont mu myaka ya za 40 kandi izwi nka "King of Plastics" kubera ibikorwa byayo byiza. Imiterere ya molekuline ya PTFE irahagaze neza, kandi imbaraga zubusabane hagati ya atome ya karubone na atome ya fluor ni ndende cyane, biha PTFE ibintu bidasanzwe bikurikira:
● Amashanyarazi:Imyenda ya PTFE ifite ibintu byiza bitarinda amazi, kandi molekile zamazi ntizishobora kwinjira hejuru yazo, kuburyo zikoreshwa kenshi mugukora imyenda nibikoresho bidafite amazi.
Guhumeka:Nubwo idafite amazi, imyenda ya PTFE ifite imiterere ya microporome ituma imyuka y'amazi inyuramo, igakomeza ihumure ryuwambaye. Uyu mutungo utuma uhitamo neza imyenda ya siporo yo hanze hamwe n imyenda ikingira.
Resistance Kurwanya imiti:PTFE irwanya cyane imiti myinshi kandi hafi ya yose ntishobora kwibasirwa nibintu byangirika nka acide, alkalis, na solde.
Resistance Kurwanya ubushyuhe:Imyenda ya PTFE irashobora kuguma itajegajega ku bushyuhe bukabije, kandi ubushyuhe bwayo bukora ni kuva kuri -200 ° C kugeza kuri + 260 ° C, bukwiranye n’ubushyuhe bwo hejuru cyangwa buke.
Co Coefficient de fraisse nkeya:PTFE ifite ubuso bworoshye cyane hamwe na coefficente yo hasi cyane, bityo ikoreshwa kenshi mubice byinganda bigomba kugabanya ubushyamirane.
Resistance Kurwanya gusaza:PTFE irwanya cyane imirasire ya ultraviolet nibindi bintu bidukikije, kandi ntabwo ikunda gusaza nyuma yo kuyikoresha igihe kirekire.
Muri byo, ikintu kigaragara cyane mu myenda ya PTFE ni imiti irwanya ruswa. Irashobora kurwanya isuri ya acide ikomeye, alkalis ikomeye nibindi bintu bya shimi, bityo ikoreshwa cyane mumyenda idasanzwe nk'imyenda irinda kirimbuzi, ibinyabuzima na shimi ndetse n imyenda ikingira imiti. Byongeye kandi, umwenda wa PTFE ufite kandi antibacterial, antistatike, guhagarika virusi nindi mirimo, bigatuma nayo iba ngombwa mubijyanye no kurinda ubuvuzi.
Mubikorwa nyabyo, imyenda ya PTFE yongewemo na nylon, polyester nizindi myenda binyuze muburyo bwihariye bwo kumurika kugirango ikore imyenda ibiri-imwe cyangwa itatu-imwe-imwe. Iyi myenda ikomatanya ntigumana gusa imikorere myiza ya firime ya PTFE, ahubwo ifite ihumure nigihe kirekire cyizindi myenda.
2. Gukoresha imirima yimyenda ya PTFE
Bitewe nimiterere yihariye yimyenda ya PTFE, yakoreshejwe cyane mubice byinshi:
Clothes Imyenda yo hanze:Imyenda ya PTFE ikoreshwa mugukora amakoti adafite amazi kandi ahumeka, ipantaro n'inkweto, bikwiranye na siporo yo hanze nko kumusozi no gusiganwa ku maguru.
Clothes Imyenda ikingira inganda:Kurwanya imiti no kurwanya ubushyuhe bituma iba ibikoresho byiza byimyambaro ikingira imiti, peteroli nizindi nganda.
Supplies Ibikoresho byo kwa muganga:Imyenda ya PTFE ikoreshwa mugukora amakanzu yo kubaga, gupfunyika indwara hamwe nibindi bikoresho byubuvuzi kugirango habeho ibidukikije.
Ibikoresho byo kuyungurura:Imiterere ya microporome ya PTFE ituma iba filteri ikora neza, ikoreshwa cyane mugusukura ikirere, gutunganya amazi nizindi nzego.
Ikirere:Ubushyuhe bwa PTFE hamwe na coefficente yo kugabanya ubukana bituma ikoreshwa mu kirere cyo mu kirere, nka kashe hamwe n’ibikoresho byo kubika.
3. Kurengera ibidukikije byimyenda ya PTFE
Nubwo imyenda ya PTFE ifite ibyiza byinshi, kurengera ibidukikije nabyo byakuruye abantu benshi. PTFE ni ibintu bigoye-gutesha agaciro, kandi bizagira ingaruka runaka kubidukikije nyuma yo kujugunywa. Kubwibyo, uburyo bwo gutunganya no guta imyenda ya PTFE byabaye ikibazo cyingenzi. Kugeza ubu, ibigo bimwe na bimwe birimo gutegura ibikoresho bya PTFE bisubirwamo kugirango bigabanye ingaruka ku bidukikije.
4. Incamake
Imyenda ya PTFE yahindutse ibikoresho byatoranijwe kubikorwa byinshi byo murwego rwohejuru kubera imbaraga zidafite amazi meza, guhumeka, kurwanya imiti, kurwanya ubushyuhe nibindi bintu. Yaba siporo yo hanze, kurinda inganda, cyangwa ubuvuzi nubuvuzi bwikirere, imyenda ya PTFE yerekanye ibyiza byihariye. Ariko, hamwe no kongera ubumenyi bwibidukikije, uburyo bwo guhangana neza n’imyanda yimyenda ya PTFE bizibandwaho mubushakashatsi niterambere.
