Kuki yitwa ptfe tube? Ni gute yitwa ptfe tube?
Umuyoboro wa polytetrafluoroethylene nawo witwaUmuyoboro wa PTFE, izwi cyane nka "Plastic King", ni polymeri ifite molekile nyinshi itegurwa hakoreshejwe tetrafluoroethylene ikora nk'imashini. Ifite ibara ry'umweru, irabagirana, irwanya ubushyuhe n'ubukonje neza, ishobora gukoreshwa igihe kirekire kuri -180 ~ 260ºC. Iki gikoresho ntikigira ibara cyangwa ibindi birungo, gifite imiterere yo kurwanya aside, alkali, n'ibindi birungo bitandukanye by'umwimerere, kandi ntigishobora gushonga mu birungo byose. Muri icyo gihe, PTFE ifite imiterere yo kurwanya ubushyuhe bwinshi, kandi ingano yayo yo gushwanyagurika ni nto cyane, bityo ishobora gukoreshwa mu gusiga amavuta no kuba irangi ryiza ryo koroshya gusukura imbere mu miyoboro y'amazi.
Uburyo bwo gukora:
Ibikoresho fatizo bya PTFE ni ifu kandi bishobora gukorwa hakoreshejwe uburyo bwo gukanda cyangwa gutunganya
Ubwoko bw'imiyoboro:
1. Umuyoboro w'amazi ukozwe mu mvange ya PTFE idafite irangi cyangwa inyongeramusaruro. Ikwiriye gukoreshwa mu ikoranabuhanga ryo mu kirere no mu gutwara abantu, ibikoresho by'ikoranabuhanga, ibikoresho by'ikoranabuhanga n'ibikoresho bikingira, mu nganda zikora imiti n'imiti, mu gutunganya ibiribwa, mu bumenyi bw'ibidukikije, mu gufata ingero z'umwuka, mu bikoresho byo kohereza amazi n'ibikoresho byo gutunganya amazi. Hari ubwoko bw'imiyoboro yose irwanya static (ikarito) cyangwa amabara.
2. Umuyoboro uvanze ukozwe mu mvange ya PTFE ya 100% idafite irangi cyangwa inyongeramusaruro. Ifite ubushobozi bworoshye bworoshye kandi burwanya imitsi kugira ngo ikore neza cyane aho hakenewe umuyoboro ukomeye wo kugonda, kongera imbaraga zo gufata cyangwa gukanda. Umuyoboro uvanze ushobora guturuka ku mirasire, uduce duto, uduce duto, cyangwa uruvange rw'imiyoboro irenze imwe. Hari ubwoko bwa anti-static (carbon) bwa miyoboro yose.
3. Imiyoboro ya capillary Imiterere y'ubushyuhe n'ubudahangarwa bw'ingufu bya capillary byakoreshejwe cyane mu nganda zirwanya ingese, nko mu nganda zikora imiti, pickling, electroplating, medicine, anodizing n'izindi nganda. Umuyoboro wa capillary ahanini ufite ubudahangarwa bwiza bwo kurwanya ingese, ubudahangarwa bwiza bwo kwanduza, ubudahangarwa bwiza bwo gusaza, ubushyuhe bwiza bwo kohereza, ubudahangarwa buke, ubunini buke, uburemere bworoheje n'imiterere mito.
Imiterere n'ubudahangarwa:
1. Irwanya ubushyuhe bwinshi, ntishobora gushonga mu bintu byose bishongesha. Ishobora kwihanganira ubushyuhe bwinshi kugeza kuri 300°C mu gihe gito, kandi ishobora gukoreshwa buri gihe hagati ya 240°C ~ 260°C, kandi ifite ubushyuhe buhamye. Uretse kuba ihura n'ibyuma bya alkali byashongeshejwe, ntabwo yangirika n'ikintu icyo ari cyo cyose, kabone n'iyo yaba yatekeshejwe muri aside hydrofluoric, aqua regia cyangwa aside sulfuric fuming, sodium hydroxide, ntabwo izahinduka.
2.Kurwanya ubushyuhe buke, gukomera neza kwa mekanike ku bushyuhe buke, nubwo ubushyuhe bwagabanuka bukagera kuri -196 ℃ butarimo gucika intege, bushobora kugumana uburebure bwa 5%.
3.Kurwanya ingese, kudakoresha imiti myinshi n'ibintu biyungurura, kudakoresha aside ikomeye na alkali, amazi n'ibindi bintu biyungurura ibinyabuzima bitandukanye, kandi bishobora kurinda ibice byabyo ingese iyo ari yo yose.
4. Irwanya gusaza, iyo ifite umutwaro mwinshi, ifite ibyiza bibiri byo kudasaza no kudafata. Ifite ubuzima bwiza bwo gusaza muri pulasitiki.
5. Gushyira amavuta menshi mu mubiri, ari na cyo gipimo cyo hasi cyane cyo gukururana mu bikoresho bikomeye. Igipimo cyo gukururana kirahinduka iyo umutwaro urimo kunyerera, ariko agaciro kari hagati ya 0.05-0.15 gusa.
6. Kudafatana, ari na byo bifite ubushyuhe buke mu bintu bikomeye, kandi ntibifatana n'ikintu icyo ari cyo cyose. Ibintu hafi ya byose ntibifatana na byo. Udupira duto cyane na two tugaragaza imiterere myiza idafatana.
7.Ni umweru, nta mpumuro, nta buryohe, ntabwo ari uburozi, kandi nta mubiri urimo. Nk'umuyoboro w'amaraso n'urugingo rw'umubiri by'ubukorano byashyizwe mu mubiri igihe kirekire, nta ngaruka mbi bigira.
8.Uburemere bworoheje n'ubworoherane bukomeye. Bishobora kugabanya cyane imbaraga z'umukoresha.
9. Ibyiza byuzuye by'iki gicuruzwa, ku buryo ubuzima bwacyo buruta cyane ubwoko butandukanye bw'imiyoboro y'umwuka isanzweho, igihe kirekire kidakenewe gusimburwa, bigabanya cyane ikiguzi cyo gukoresha, bikongera imikorere myiza, ubukungu n'imikorere.
Ahantu ho gukorerwa:
Ikoreshwa mu nganda z'amashanyarazi
Mu by’indege, iby’indege, iby’ikoranabuhanga, ibikoresho, mudasobwa n’izindi nganda nk’urwego rwo gukingira ingufu n’imirongo y’ibimenyetso, ibikoresho birwanya ingese cyangwa byangirika bishobora gukoreshwa mu gukora filime, impapuro z’imiyoboro, ibyuma bipima amazi, imashini zimesa, valves n’imiyoboro ya chimique, imiyoboro y’amazi, imiyoboro y’ibikoresho, n’ibindi.
Ikoreshwa mu bijyanye n'ibikoresho by'amashanyarazi
inganda z’imiti, indege, imashini, nibindi aho gukoresha ibikoresho by’ikirahure bya quartz, bikoreshwa mu gusesengura imiti no kubika aside zitandukanye, alkali, n’ibintu bisukura ibinyabuzima mu ngufu za atome, ubuvuzi, semiconductor n’izindi nganda. Bishobora gukorwamo ibice by’amashanyarazi bifite insinga nyinshi, insinga nini n’icyuma gikingira insinga, ibikoresho bya shimi birwanya ingese, imiyoboro y’amavuta ikonje cyane, ibice by’ubukorano, nibindi. Bishobora gukoreshwa nk'inyongera ku bikoresho bya pulasitiki, kabureti, irangi, irangi, amavuta, nibindi.
Iki gicuruzwa kirwanya ubushyuhe bwinshi n'ingese
Ifite ubushobozi bwo gukingira amashanyarazi neza, irwanya gusaza, amazi make, kandi ikora neza mu kwisiga. Ni ifu ikoreshwa mu kwisiga ikwiriye ibikoresho bitandukanye kandi ishobora gukoreshwa vuba kugira ngo ikore firime yumye, ikoreshwa nk'isimbura grafiti, molybdenum n'andi mavuta adafite umwimerere. Ni umuti ukuraho ibumba ukwiriye polimeri za thermoplastic na thermosetting zifite ubushobozi bwo gutwara neza. Ikoreshwa cyane mu nganda za elastomer na rubber ndetse no kurwanya ingese.
Ikoreshwa nk'icyuzuzo cya epoxy resin kugira ngo yongere ubushobozi bwo kudashira, kudashyuha no kudashira kw'ibirungo bya epoxy
Ikoreshwa cyane cyane nk'icyuma gifunga no kuzuza imigati y'ifu
