Shin kun ji labarin kayan PTFE daFarashin PTFE?To, bari mu ga ko za mu iya amsa wasu tambayoyi game da shi.

Polytetrafluoroethylene (polytetrafluoroethylene) an rage shi da PTFE, wanda aka fi sani da "sarkin filastik", kuma sunan kasuwancinsa Teflon.A kasar Sin, saboda lafazin lafuzza, ana kuma kiran "TEFLON" da Teflon, dukkansu fassarar Teflon ne.Polytetrafluoroethylene da aka sani da "sarkin robobi", mahaifin fluororesin Roy Planck 1936 DuPont kamfanin a Amurka ya fara nazarin maye gurbin Freon.Sun tattara tetrafluoroethylene kuma sun adana su a cikin silinda don gwaji na gaba washegari.Koyaya, lokacin da aka buɗe bawul ɗin taimako na silinda washegari, babu iskar gas da ta cika.Sun yi tsammanin ya zubo ne, amma lokacin da ake auna silinda, sai suka ga cewa silinda bai yi nauyi ba.Sun ga ta cikin silinda kuma suka sami farin foda mai yawa, wanda shine polytetrafluoroethylene.Sun gano cewa polytetrafluoroethylene yana da kyawawan kaddarorin kuma za'a iya amfani dashi azaman anti narkewa sealing gasket ga atomic bama-bamai da bawo.Don haka, sojojin Amurka sun kiyaye sirrin fasahar a lokacin yakin duniya na biyu.Sai da aka kawo karshen yakin duniya na biyu aka raba shi da bunkasa masana'antu a shekarar 1946. Bincike masu alaka:Farashin PTFE, PTFE corrugated tiyo

Polytetrafluoroethylene za a iya kafa ta hanyar matsawa ko extrusion;Hakanan za'a iya sanya shi cikin watsawar ruwa don sutura, impregnation ko fiber.Polytetrafluoroethylene (PTFE) ana amfani dashi sosai a cikin masana'antar makamashin atomic, tsaron ƙasa, sararin samaniya, lantarki, lantarki, injiniyan sinadarai, injina, kayan kida, kayan gini, gini, yadi, jiyya na saman ƙarfe, magunguna, likitanci, yadi, abinci, ƙarfe da ƙari. masana'antu na narkewa, da sauransu, wanda ya sa ya zama samfurin da ba za a iya maye gurbinsa ba.

PTFE shine taƙaitaccen bayanin polytetrafluoroethylene - kalma ce mai tsawo, amma dogon lokaci dole ne 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 firinta na 3D, bututun ciyar da injin kofi, bututun tsarin sanyaya ruwa da tsarin bututun birki?

1) PTFE bututu yana da kwanciyar hankali na sinadarai kuma yana iya jure wa aikin duk acid mai ƙarfi, gami da aqua regia, hydrofluoric acid, hydrochloric acid mai ƙarfi, acid nitric, sulfuric acid fuming, acid acid, tushe mai ƙarfi, mai ƙarfi mai ƙarfi, mai ragewa wakili da nau'ikan kwayoyin halitta. abubuwan narkewa.Ana amfani da shi sosai wajen isar da ruwa mai tsauri daban-daban.

2) Ana iya amfani da na dogon lokaci a cikin kewayon - 80 ℃ - + 280 ℃.Yana iya aiki a zafin jiki mai daskarewa ba tare da ƙwanƙwasa ba da narkewa a babban zafin jiki.

3) The fice non danko da anti danko yana da kyau kwarai, da kuma ciki bango na bututu ba ya manne da colloids da sunadarai, don haka ba zai samar da datti Layer a cikin bututu.

4) Kyakkyawan aikin rufin lantarki Teflon wani abu ne mai mahimmanci wanda ba na iyakacin duniya ba tare da kyawawan kaddarorin dielectric, babban juriya da dielectric akai-akai na kusan 2.0, wanda shine mafi ƙanƙanta a cikin duk kayan haɗin wutar lantarki, kuma canjin yanayin zafi da mita yana da ɗan tasiri a kansu. .

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

6) Kyakkyawan kwanciyar hankali na thermal, Teflon yana da incombustibility mai mahimmanci, ƙimar iyakar iskar oxygen yana sama da 95, yana iya narkewa kawai a cikin harshen wuta, baya haifar da ɗigon ruwa, kuma ana iya yin carbonized kawai.

7) Babban laushi da juriya na lankwasawa.

8) juriya na danshi: fuskar fim din Teflon ba shi da ruwa da man fetur, kuma ba shi da sauƙi a lalata tare da bayani yayin aikin samarwa.Idan akwai ɗan ƙaramin ƙazanta da ke manne, ana iya cire shi ta hanyar shafa mai sauƙi.Yana da fa'idodi na ɗan gajeren lokaci, ceton sa'a na mutum da haɓaka ingantaccen aiki.

9) Wear juriya: kyakkyawan juriya na lalacewa a ƙarƙashin babban kaya.Ƙarƙashin ƙayyadaddun kaya, yana da fa'idodin juriya na lalacewa da rashin mannewa.

Polytetrafluoroethylene tiyo yana da wasu abũbuwan amfãni a kan talakawa roba layi tiyo.

Na farko, tiyo polytetrafluoroethylene (PTFE) yana aiki a matsayin shinge na tururi, wanda ba ya dagewa a lokaci guda na tsayin daka mai zafi, kuma yana iya biyan bukatun waɗannan inji da kayan aiki don amfani da bututu.

Na biyu, tiyo mai layi na PTFE yana da mafi girman juriya na sinadarai kuma yana tallafawa nau'ikan ruwa na mota waɗanda roba ta yau da kullun ba za ta iya bayarwa ba, galibin haɗaɗɗen gas mai ɗauke da ethanol.Tushen roba na yau da kullun zai lalace lokacin da aka fallasa shi da irin wannan man fetur kuma a ƙarshe ya ƙasƙanta ta yadda zai iya fara zubewa ko allurar mai, wanda ke da haɗari sosai.

Na uku, Teflon liyi tiyo yana da matukar high zafin jiki juriya - a gaskiya ma, aiki zafin jiki kewayon tiyo sayar da PTFE tubes ne - 65 ° C zuwa + 260 ° C. Ya dace sosai don amfani a kan wadannan na'urorin.

Na hudu, Teflon tube Teflon tiyo yana da matsananciyar aiki sosai, yana sake tabbatar da cewa zaku iya amfani da shi don kowane nau'ikan aikace-aikacen mota da sandar zafi.Girman An6 don 2500psi, girman an8 don 2000psi, har ma mafi yawan aikace-aikacen da ake buƙata, matsa lamba ya fi isa.

sauran?Ee, a gaskiya - braided a cikin tiyo mu yana tabbatar da tsawon rayuwar sabis da bayyanar kaifi don shigarwa.Lokacin da kuka zaɓi bakin karfe, yana da kyan gani kuma yana ba ku ƙwararren injiniyan bututun jin zafi.Black nailan idan kuna son kallo mai laushi.Amma ka sani, har yanzu baki nailan yana da rufin bakin karfe.Muna buƙatar kawai mu sanya bakin karfe da baƙar nailan don samun wani salo na daban.

Yanzu akwai - shuɗi da ja Nylon Braided PTFE liyi tiyo mai zafi sanda mai zafi girman an6.

Don haka PTFE tiyo yana da kyau - menene ke damunsa?

Gabaɗaya, bututun PTFE na iya maye gurbin mafi yawan al'amuran bututun roba.Rashin lahani na bututun PTFE shine cewa sassaucin sa bai kai na bututun roba ba.Koyaya, jerin bellows na bututun PTFE yana da wasu sassauƙa, wanda zai iya magance wannan ƙaramin lahani.Amma akwai wasu abubuwan da kuke buƙatar sani.

1 - don tiyo mai layi na PTFE, kuna buƙatar amfani da kayan aiki masu dacewa daga masana'anta guda ɗaya don tabbatar da hatimi mai kyau akan kayan aikin.Tun da an halicci hatimi tare da ferrule maimakon sakawa a kan bututun roba, ana buƙatar ƙarin kulawa lokacin yanke.Don ƙarin bayani, duba umarnin shigarwa.

Radius na lanƙwasawa na 2-ptfe tiyo ya fi stringent saboda zai zama sauƙi don kink idan ya wuce ƙayyadaddun bayanai.Don ƙarin bayani, duba labarin mu akan radius lanƙwasa.

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