Chii chinogadzirwa neptfe tube?
Product sumo
1,Ptfe chubhunderimwe zita repolytetrafluoroethylene, chipfupiso chechirungu ndiPTFE, (inowanzozivikanwa se "Plastic King, Hara"), uye kemikari formula ndeye -(CF2-CF2)n-.Polytetrafluoroethylene yakawanikwa netsaona muna 1938 nekemisitiri Dr. Roy J. Plunkett muDuPont.'s Jackson Laboratory muNew Jersey, USA Paakaedza kugadzira chlorofluorocarbon itsva Munyaya yecompound refrigerant.Zvigadzirwa zvechinyorwa ichi zvinowanzo kunzi "isina-stick coating";chinhu chekugadzira polymer chinoshandisa fluorine kutsiva ese maatomu ehydrogen mu polyethylene.Nyaya iyi inoshingirira kuacids, alkalis, uye akasiyana organic solvents, uye inenge isinganyungudike mune zvese zvinonyungudutsa.Panguva imwecheteyo, PTFE ine maitiro ekudzivirira kupisa kwepamusoro, uye friction coefficient yakaderera zvikuru, saka inogona kushandiswa senzira yekuzora, uye yave yakave yakashongedzwa yakanakira yemukati wemukati wehari dzisina tsvimbo. uye pombi dzemvura
Izvi zvigadzirwa zvinhu zvinonyanya kushandiswa pane zvinotevera zvigadzirwa:
PTFE, FEP, PFA, ETFE, AF, NXT, FFR.
PTFE: PTFE (polytetrafluoroethylene) isina-stick coating inogona kushandiswa kuenderera pa260°C, ine tembiricha yekushandisa yakawanda ye290-300°C, yakanyanya kuderera friction coefficient, yakanaka kupfeka kuramba uye yakanakisa kugadzikana kwemakemikari.
FEP: FEP (fluorinated ethylene propylene copolymer) isina-tsvimbo yekuputira inonyunguduka uye inoyerera ichiita firimu risiri-porous panguva yekubika.Iyo ine yakanakisa kugadzikana kwemakemikari uye yakanakisa isiri-tsvimbo maitiro.Iyo yakanyanya kupisa tembiricha ndeye 200℃.
PFA: PFA (perfluoroalkyl compound) isina-stick coating inonyunguduka uye inoyerera panguva yekubika kuumba firimu risina porous seFEP.Chakanakira chePFA ndechekuti ine tembiricha yekuenderera mberi kwekushandisa kwe260°C, kuomarara kwakasimba uye kuomarara, uye inonyanya kukodzera kushandiswa mukurwisa-kunamatira uye makemikari kuramba maapplication pasi pemamiriro ekushisa.
PTFE (Polytetrafluoroethene) chinhu chakagadzirwa chepolymer chinoshandisa fluorine kutsiva ese maatomu ehydrogen mupolyethylene.Nyaya iyi inoshingirira kuacids, alkalis, uye akasiyana organic solvents, uye inenge isinganyungudike mune zvese zvinonyungudutsa.Panguva imwecheteyo, ptfe chubhu ine maitiro ekudzivirira kupisa kwakanyanya, uye friction coefficient yayo yakadzikira, saka inogona kushandiswa pakuzora, uye yave zvakare yakanakira kupfekedza kune nyore-ku-kuchenesa woks nemapombi emvura.Inogona kushandiswa papipeline corrosion resistance, yakakwirira uye yakaderera tembiricha kuramba, uye corrosion kuramba.Inoshandiswa munzvimbo dzakaoma senge lubrication, engineering, zvemagetsi, midziyo yemagetsi, uye ndege.
Product features
1, Yakakwirira uye yakaderera tembiricha kuramba: zvishoma mhedzisiro pane tembiricha, yakafara tembiricha siyana, inoshanda tembiricha -65 ~ 260 ℃.
2, Isiri-yakanamatira: Zvinenge zvinhu zvese hazvina kusungirirwa kune PTFE firimu.Mafirimu akaonda kwazvo anoratidzawo kuita kwakanaka kusingapindire.2. Kupisa kupisa: PTFE coating film ine yakanakisa kupisa kusagadzikana uye yakaderera tembiricha kuramba.Inogona kumira tembiricha yakakwira kusvika 300 ° C munguva pfupi, uye kazhinji inogona kushandiswa nguva nenguva pakati pe240 ° C uye 260 ° C.Iine kugadzikana kwakanyanya kwekushisa.Inogona kushanda pakutonhora kwechando pasina embrittlement uye hainyunguduki pakupisa kwakanyanya.
3, Sliding chivakwa: PTFE yekuputira firimu ine yakakwira coefficient yekupokana.Iko friction coefficient inoshanduka kana mutoro uchitsvedza, asi kukosha kuri pakati pe0.05-0.15 chete.
4, Kuramba kwehunyoro: Iyo yepamusoro yePTFE yekuputira firimu haina kunamatira kumvura nemafuta, uye hazvisi nyore kunamatira kune mhinduro panguva yekugadzira mashandiro.Kana pane tsvina shoma, ingoipukuta.Nguva pfupi yakapambadzwa, kuchengetedza maawa ekushanda nekuvandudza kushanda zvakanaka.
5, Pfeka kuramba: Iyo ine yakanakisa kupfeka kuramba pasi pemutoro wakakwira.Pasi pemumwe mutoro, ine zvipingamupinyi zviviri zvekudzivirira kupfeka uye kusapindira.
6, Corrosion resistance: PTFE haina kana kusvibiswa nemakemikari, uye inokwanisa kumira maasidhi akasimba (kusanganisira aqua regia) uye maoxidants akasimba kunze kwesimbi yakanyungudutswa yealkali, fluorinated media uye sodium hydroxide pamusoro pe300 ° C.Basa rekudzikisa agent uye akasiyana organic solvents anogona kuchengetedza zvikamu kubva kune chero rudzi rwemakemikari corrosion
makemikari pfuma
1, Insulation: Haina kukanganiswa nemhoteredzo uye frequency, vhoriyamu kuramba inogona kusvika 1018 ohm · cm, iyo dielectric kurasikirwa idiki, uye kuparara kwemagetsi kwakakwira.
2 、 Yakakwirira uye yakaderera tembiricha kuramba: zvishoma mhedzisiro pane tembiricha, yakafara tembiricha siyana, inoshanda tembiricha -190 ~ 260 ℃.
3, Kuzvizora: Iyo ine diki coefficient yekupokana pakati pemapurasitiki uye yakanaka isina mafuta yekuzora zvinhu.
4, Surface isiri-kunamira: inozivikanwa yakasimba zvinhu hazvigone kunamatira kumusoro, chinhu chakasimba chine simba diki repamusoro.
5, Kuramba kwemamiriro ekunze, kuramba kwemwaranzi uye kuderera kwemhepo: kuratidzwa kwenguva refu kumhepo, nzvimbo uye kuita zvinoramba zvisingachinji.
6, Incombustibility: Iyo oxygen muganho index iri pazasi 90.
7, PTFE inoshandiswa zvakanyanya mumaindasitiri anoda yakakwirira tembiricha kuramba uye yakakwirira viscosity.Iyo yakasimba kwazvo super acid-fluoroantimonic acid inogona zvakare kushandiswa kuchengetedza
Chigadzirwa chekushandisa nzvimbo
Polytetrafluoroethylene inogona kuumbwa nekusundidzira kana extruding;inogonawo kugadzirwa mufirimu uye yobva yacheka mugomba-yakaiswa PTFE tepi kana ichishandiswa mumatare epamusoro-tembiricha.Inoshandiswa kugadzira tambo dzepamusoro-frequency uye yakananga kuita kupararira kwemvura.Inogona kushandiswa kugadzira, kuisa mukati kana fiber kugadzira.
Polytetrafluoroethylene inoshandiswa zvakanyanya mumaindasitiri akadai sesimba renyukireya, kudzivirira kwenyika, aerospace, zvemagetsi, zvemagetsi, makemikari, michina, zviridzwa, metres, kuvaka, machira, simbi pamusoro kurapwa, mishonga, kurapwa, chikafu, simbi uye kunyungudutswa, etc. Corrosive zvinhu, zvinhu zvinodzivirira, anti-stick coatings, nezvimwewo zvinoita kuti ive chigadzirwa chisingachinjiki.
PTFE hoseine yakatanhamara yakanakisa yakazara zvivakwa, yakakwira tembiricha kuramba, corrosion resistance, isiri-tsvimbo, self-lubricating, yakanakisa dielectric zvivakwa, uye yakaderera kwazvo kukweshera coefficient.Inoshandiswa semapurasitiki einjiniya, inogona kugadzirwa kuva PTFE machubhu, tsvimbo, mabhandi, ndiro, mafirimu, etc. Kazhinji inoshandiswa mumapaipi asingadziviriri, midziyo, pombi, mavharuvhu, radar, midziyo yekukurukurirana, redhiyo, radomes, etc. nepamusoro pekuita zvinodiwa.Kuwedzera chero kuzadza kunogona kumira tembiricha yekupisa ye polytetrafluoroethylene, ma mechanical properties anogona kuvandudzwa zvikuru.Panguva imwecheteyo, zvimwe zvakanakisa zvimiro zvePTFE zvinochengetwa.Mhando dzakazadzwa dzinosanganisira girazi faibha, simbi, simbi oxide, graphite, molybdenum disulfide, kabhoni faibha, polyimide, EKONOL, nezvimwe.
