Polytetrafluoroethylene (PTFE) pombi chigadzirwa chakasiyana-siyana chinogona kupa huwandu hwakawanda hwekushandisa mumaindasitiri mazhinji akasiyana.Iyo inogadzirwa uchishandisa paste extrusion nzira.Iyo PTFE pombi inogadzirwa namatidza extrusion inochinjika.Inogona kugadzira mapaipi ePTFE ane dhayamita yemukati diki se 0.3 mm kusvika pakureba 100 mm uye ukobvu hwemadziro hudiki se 0.1 mm kusvika 2 mm.PTFE hoseine yakanakisa kugadzikana kwekemikari, inokwanisa kumira kune ese akasimba asidhi, alkali yakasimba, yakasimba oxidants, uye haidyidzane neakasiyana organic solvents.Inogona kushandiswa zvakajairika mukati -60 ℃～+260 ℃, ine yakavimbika uye yakanakisa corrosion resistance.Inogona kutakura gasi rinoparadza rakasimba uye mvura pane tembiricha yakakwira.Uye zvakare, mushure mekurapwa pane yakakwira tembiricha 260 ℃ ye1000h, maitiro ayo emagetsi ane shanduko shoma.PTFE ine yakaderera friction factor, yakanaka anti-friction, self-lubricating material, its static friction coefficient ishoma pane dynamic friction coefficient, saka kutakura kwakaitwa kubva mairi kune zvakanakira kuderera kwekutanga kuramba uye kushanda kwakagadzikana.Nekuti PTFE haina-polar, inodzivirira kupisa uye haitore.Iyo zvakare ine yakanakisa kuchembera kuramba, kusanamatira uye kusapisa.Izvi hazvigoni kutsiviwa nemamwe hose
Iyi inotevera sumo ndiko kushandiswa kwePTFE hose mumaindasitiri akasiyana:
1.Chemical industry
Nekuti ivo vane yakakwira makemikari kuramba kune anenge ese makemikari,PTFE tubingisarudzo yakanaka muindasitiri yemakemikari.Kusanganisira iyo semiconductor indasitiri.Iyo yazvino maitiro ekugadzirwa kwesemiconductor inoda yakachengeteka metering uye kutakurwa kwezvinwiwa zvinoparadza (asidhi nemaalkali).Izvi zvichakuvadza zvakanyanya pombi yekutumira munguva pfupi
2.Medical industry
Izvo zvakakosha zvePTFE mapaipi anosanganisirawo nyore-ku-kuchenesa nzvimbo yepasi.Mumakore gumi apfuura, machubhu ePTFE ave achiwedzera kushandiswa mumidziyo yekurapa.Nekuda kweiyo yakaderera coefficient of friction yePTFE chubhu, izvi zvinoreva kuti nzvimbo yaro yakanyatso kutsetseka uye haizovharidzi kana kubatsira mabhakitiriya kukura.Pakati pavo, hoses inoshandiswa intubation, catheters, pipettes uye endoscopes.Inogadzirawo zviridzwa zvakasiyana-siyana nemidziyo, senge pombi dzekudonhedza, mafevha, mhete, apuro rabha, magurovhosi uye mamwe matushu ekugadzira.Pamusoro pezvo, midziyo yakawanda inoshanda inoshandiswa navanachiremba mukuongorora kwevanhu biochemical inogadzirwawo nePTFE zvinhu
3.Indasitiri yendege
PTFE hoses haisi-kupisa fluoropolymers.Coefficient yavo yakaderera yekukwesha inovabvumira kushanda pasi pekupisa kwakanyanya uye kumanikidzwa.Ndosaka machubhu aya achishandiswa neveindasitiri yendege kuputira waya netambo
4.Automobile industry
Muinjini dzemotokari, mapaipi emafuta emhando yepamusoro akagadzirwa nePTFE anoshandiswa kunyudza mafuta uye njanji yemafuta.Parizvino, Mabhureki hose pamusika ese mabhureki hose maassemblies ane majoini.Zvinoenderana nemhando dzakasiyana dzemota mabhureki, yakakamurwa kuita hydraulic brake hoses, pneumatic brake hoses uye vacuum brake hoses.Zvinoenderana nezvayo, yakakamurwa kuita PTFE brake hose, rabha brake hose uye nylon brake hose.Rubber brake hose ine mabhenefiti esimba rakasimba rekusimba uye nyore kuisirwa, asi iyo yakashata ndeyekuti iyo nzvimbo inononoka kuchembera mushure mekushandisa kwenguva refu.Kana iri tembiricha yakaderera, simba rekusimba renylon brake hose harina simba, kana rakakanganiswa nekunze kwesimba, zviri nyore kutyora.Zvisinei,Besteflon's PTFE chubhuine hunhu hwekushisa kwepamusoro uye kushomeka kwekushisa, kupikisa kwepamusoro, kusagadzikana kweabrasion, uye kushorwa kwemarara, izvo zvinoita kuti ive nehupenyu hurefu hwebasa uye haidi kuchinjwa kazhinji.Anokwanisa kugadzirisa kukanganisa kwezvimwe zvinhu zviviri
5.Indasitiri yemagetsi
PTFE tubing ine yakanakisa magetsi maitiro.Ivo vane yakakwira dielectric inogara uye yakaderera kurasikirwa chinhu hunhu mune yakakura kwazvo frequency renji.Naizvozvo, mapaipi ePTFE anoshandiswa semhando yepamusoro, yepamusoro-tembiricha insulating zvinhu zvewaya netambo, pamwe nemagetsi ekudziya zvinhu uye tembiricha sensors.Mumagetsi emagetsi, kuitira kuvhara tambo uye tambo, mapipe epamusoro ePTFE anoshandiswa, anogona kumira kutonhora kwepamusoro uye kudzivirira waya kubva kune chero kucheka.Pamusoro pezvo, machubhu aya anouya nemavara akasiyana-siyana kubatsira kuona waya dzemumba kana muhofisi
6.Food industry
Nekuda kweiyo nyore-ku-kuchenesa uye isina-tsvimbo maitiro, PTFE polytetrafluoroethylene mapaipi anogona kushandiswa muindasitiri yezvekudya.Kunyanya, machubhu akagadzirwa asina kuzadzwa PTFE akakodzera nekuda kwekusarerekera kwavo kwepanyama uye anotevedzera nhungamiro yeUS Food and Drug Administration.Nokudaro, zvakaratidzwa kuti hazvikuvadzi kusangana nepurasitiki uye chero rudzi rwezvokudya.Naizvozvo, PTFE machubhu anowanzo shandiswa mumachina ekofi echinyakare.Mukuwedzera, iyo inonzi single-chamber kana multi-chamber design spaghetti tubes uye kupisa-shrinkable tubes zvinoshandiswa.PTFE zvigadzirwa zvinogona sterilized uchishandisa ese akajairika nzira
7.Textile industry
Kuendeswa kwemakemikari mumapombi anoshandiswa muindasitiri yemachira kunogona kukonzera ngura.Naizvozvo, kuitira kudzivirira dambudziko iri, TPFE chubhu inoshandiswa, uye PTFE coating inoitwa pajira remachira.
8.3D Dhinda Indasitiri
Mukudhinda kwe3D, iyo filament inofanirwa kuendeswa kune inodhinda nozzle iyo inofanirwa kuitwa mukupisa kwepamusoro.Sezvo PTFE tubing ine tembiricha yakakwira coefficient uye isiri-tsvimbo zvivakwa, inobatsira kutsvedza zviri nyore zvinhu kubva mumuromo, saka ndiyo inonyanya kudiwa polima muindasitiri yekudhinda ye3D.
Iyo isiri-alkaline ye PTFE inobvumira kuti ishandiswe muindasitiri yemakemikari, uko kuendeswa kwemvura yakanyanya kusimba inowanzoitika.Zhongxin Fluorine plastic Industry Co., Ltd. Nyanzvi mukugadzirwa kwemhando yepamusoro PTFE hoses kwemakore gumi nematanhatu.
