Shin kun ji labarin kayan PTFE da kumaTiyo na PTFETo, bari mu gani ko za mu iya amsa wasu tambayoyi game da shi.

Polytetrafluoroethylene (polytetrafluoroethylene) an takaita shi da PTFE, wanda aka fi sani da "sarkin filastik", kuma sunan kasuwancinsa shine Teflon. A kasar Sin, saboda yadda ake furtawa, ana kuma kiran "TEFLON" da Teflon, wanda duk an fassara su ne da Teflon. Polytetrafluoroethylene an san shi da "sarkin filastik", mahaifin kamfanin fluororesin Roy Planck na 1936 DuPont a Amurka ya fara nazarin madadin Freon. Sun tattara wasu tetrafluoroethylene suka adana su a cikin silinda don gwaji na gaba washegari. Duk da haka, lokacin da aka bude bawul din rage matsin lamba na silinda washegari, babu wani iskar gas da ya cika. Sun yi tunanin zubewa ce, amma lokacin da aka auna silinda, sun gano cewa silinda bai rage nauyi ba. Sun gani ta cikin silinda kuma suka sami farin foda da yawa, wanda shine polytetrafluoroethylene. Sun gano cewa polytetrafluoroethylene yana da kyawawan halaye kuma ana iya amfani da shi azaman gasket ɗin rufewa na hana narkewa don bama-bamai da harsashi na atomic. Saboda haka, sojojin Amurka sun ɓoye fasahar a lokacin Yaƙin Duniya na Biyu. Sai bayan ƙarshen Yaƙin Duniya na Biyu ne aka cire sunan ƙasar aka kuma mayar da ita masana'antu a shekarar 1946. Bincike Masu Alaƙa:Tiyo mai layi na PTFE, Tiyo mai rufi na PTFE

Ana iya samar da Polytetrafluoroethylene ta hanyar matsewa ko fitar da shi; kuma ana iya yin shi ya zama watsa ruwa don rufewa, danshi ko zare. Ana amfani da Polytetrafluoroethylene (PTFE) sosai a masana'antar makamashin atomic, tsaron ƙasa, sararin samaniya, lantarki, injiniyan sinadarai, injiniyoyi, kayan aiki, kayan aiki, gini, yadi, maganin saman ƙarfe, magunguna, likitanci, yadi, abinci, masana'antar ƙarfe da narkar da ƙarfe, da sauransu, wanda hakan ya sa ya zama samfuri da ba za a iya maye gurbinsa ba.

PTFE ita ce taƙaitaccen bayanin polytetrafluoroethylene - kalma ce mai tsawo, amma dogon yana nufin yana da kyau! Sunan alamar kasuwanci na polytetrafluoroethylene shine sunan da aka fi sani da polytetrafluoroethylene.

Me yasa ake amfani da bututun polytetrafluoroethylene (PTFE) a cikin bututun inkjet na firintar 3D, bututun ciyar da injin kofi, bututun tsarin sanyaya ruwa da tsarin bututun birki?

1) Bututun PTFE yana da ƙarfin juriyar sinadarai kuma yana iya jure wa dukkan sinadarai masu ƙarfi, gami da aqua regia, hydrofluoric acid, hydrochloric acid mai ƙarfi, nitric acid, fuming sulfuric acid, organic acid, strong base, strong oxidant, reducer agent da kuma daban-daban organic solvents. Ana amfani da shi sosai wajen isar da ruwa mai ƙarfi daban-daban.

2) Ana iya amfani da shi na dogon lokaci a cikin kewayon - 80 ℃ - + 280 ℃. Yana iya aiki a yanayin sanyi ba tare da lalacewa ba kuma yana narkewa a babban zafin jiki.

3) Babban rashin danko da kuma hana danko yana da kyau kwarai da gaske, kuma bangon ciki na bututun baya manne da colloids da sinadarai, don haka ba zai samar da wani datti a cikin bututun ba.

4) Kyakkyawan aikin rufin lantarki Teflon abu ne mai matuƙar rashin polar wanda ke da kyawawan halayen dielectric, juriya mai ƙarfi da kuma dielectric constant na kusan 2.0, wanda shine mafi ƙanƙanta a cikin duk kayan rufin lantarki, kuma canjin zafin jiki da mita ba shi da tasiri sosai a kansu.

5) Kyakkyawan juriya ga tsufa da juriya ga radiation, ana iya amfani da shi a waje na dogon lokaci.

6) Kyakkyawan kwanciyar hankali na zafi, Teflon yana da matukar amfani wajen hana konewa, ma'aunin iyakar iskar oxygen dinsa ya wuce 95, yana iya narkewa ne kawai a cikin harshen wuta, baya samar da digo, kuma ana iya yin amfani da iskar carbon ne kawai.

7) Babban laushi da juriya ga lanƙwasawa.

8) juriya ga danshi: saman fim ɗin Teflon ba shi da ruwa da mai, kuma ba shi da sauƙi a yi masa tabo da ruwan magani yayin aikin samarwa. Idan akwai ƙaramin ƙura a manne, ana iya cire shi ta hanyar gogewa mai sauƙi. Yana da fa'idodin ɗan gajeren lokacin aiki, yana adana sa'o'i na aiki da inganta ingancin aiki.

9) Juriya ga lalacewa: juriya ga lalacewa mai kyau a ƙarƙashin nauyi mai yawa. A ƙarƙashin wani nau'in kaya, yana da fa'idodin juriya ga lalacewa da rashin mannewa.

Bututun Polytetrafluoroethylene yana da wasu fa'idodi fiye da bututun roba na yau da kullun.

Da farko, bututun polytetrafluoroethylene (PTFE) yana aiki a matsayin shingen tururi, wanda ba ya mannewa a lokaci guda na juriyar zafi mai yawa, kuma yana iya biyan buƙatun waɗannan injuna da kayan aiki don amfani da bututu.

Na biyu, bututun PTFE mai layi yana da mafi girman juriya ga sinadarai kuma yana tallafawa nau'ikan ruwa na mota waɗanda robar yau da kullun ba za ta iya bayarwa ba, wanda aka fi sani da haɗin mai wanda ke ɗauke da ethanol. Bututun roba na yau da kullun zai ruɓe lokacin da aka fallasa shi ga irin wannan man fetur kuma daga ƙarshe ya lalace har ya fara zubewa ko kuma ya yi allurar mai, wanda hakan yana da haɗari sosai.

Na uku, bututun Teflon mai layi yana da juriya sosai ga zafin jiki - a zahiri, kewayon zafin aiki na bututun da aka sayar da bututun PTFE shine - 65° C zuwa + 260° C. Ya dace sosai don amfani akan waɗannan na'urori.

Na huɗu, bututun Teflon yana da matsin lamba mai yawa, yana kuma tabbatar da cewa za ku iya amfani da shi don duk nau'ikan aikace-aikacen mota da sandar zafi. Girman An6 don 2500psi, girman an8 don 2000psi, har ma da aikace-aikacen da suka fi buƙata, matsin lambarsa ya fi isa.

wani? Haka ne, a zahiri - an kitsa a cikin bututunmu yana tabbatar da tsawon rai da kuma kamannin da aka yi amfani da shi don shigarwa. Lokacin da ka zaɓi bakin ƙarfe, yana da kamannin da ya yi kaifi kuma yana ba ka jin daɗin ƙwararren injinan bututu. Nailan baƙi idan kana son kamannin da ya yi laushi. Amma ka sani, nailan baƙi har yanzu yana da rufin ƙarfe mai kauri. Kawai muna buƙatar shafa bakin ƙarfe da nailan baƙi don samun kamanni daban.

Yanzu akwai - shuɗi da ja na Nylon Braided PTFE lined tiyo mai lankwasa girman bututun mai mai zafi an6.

Don haka bututun PTFE yana da kyau - me ke damun sa?

Gabaɗaya, bututun PTFE zai iya maye gurbin mafi yawan yanayin bututun roba. Abin da kawai ke da illa ga bututun PTFE shine sassaucinsa bai yi kyau kamar bututun roba ba. Duk da haka, jerin bututun PTFE na bellows yana da wasu sassauci, wanda zai iya magance wannan ƙaramin lahani kaɗan. Amma akwai wasu abubuwa da kuke buƙatar sani.

1 - Don bututun PTFE mai layi, kuna buƙatar amfani da kayan haɗin da suka dace daga masana'anta ɗaya don tabbatar da kyakkyawan rufewa akan kayan haɗin. Tunda an ƙirƙiri hatimin da ferrule maimakon sakawa akan bututun roba, yana buƙatar a yi taka tsantsan yayin yankewa. Don ƙarin bayani, duba umarnin shigarwarmu.

Radius mai lanƙwasa na bututun 2-ptfe ya fi tsauri domin zai fi sauƙi a lanƙwasa idan ya wuce ƙa'idar da aka ƙayyade. Don ƙarin bayani, duba labarinmu kan radius mai lanƙwasa.

Ba haka lamarin yake da bututun mai mai zafi ba, amma idan ka yi siyayya a kusa,Tiyo na PTFEyawanci ya fi tsada fiye da bututun roba mai layi - farashin bututun mai mai zafi yana da kyau sosai, sau da yawa farashin bututun roba sau da yawa, kuma zai daɗe na dogon lokaci.
