PTFE ndiyo purasitiki yakasimba kwazvo inozivikanwa parizvino.Inoshandiswa zvakanyanya mumaindasitiri akasiyana ane nharaunda dzakaomarara.Nekuda kwekuita kwayo kwakanakisa, zvishoma nezvishoma yave chigadzirwa chikuru muzvigadzirwa zvepurasitiki (Iyo yese inonzi Polytetrafluoroethylene).Nokudaro, kunewo vagadziri vakawanda uye vakawanda vanogadzira zvigadzirwa zvakadaro.PTFE inogona kugadzirwa mumhando dzakawanda dzezvigadzirwa, senge machubhu, tsvimbo, ndiro, gaskets, mafirimu, nezvimwewo, izvo zvinoshandiswa munzvimbo dzakasiyana siyana.
Chii chinonzi PTFE chubhu?
Polytetrafluoroethylene (yakapfupikiswa sePTFE), inowanzo zivikanwa se "Plastic King", ndeyepamusoro molecular polymer inowanikwa ne polymerizing tetrafluoroethylene semonomer, iyo ichena kana inopenya.Ichi chinyorwa hachina chero pigment kana additives, uye ine hunhu hweasidhi uye alkali kuramba, kuramba kune akasiyana organic zvinonyungudutsa, uye inenge isinganyungudika mune zvese zvinonyungudutsa.Mukuwedzera, PTFE ine tembiricha yakakura uye inogona kushandiswa kwenguva yakareba pa -65 ° C ~ 260 ° C pasi pekumanikidzwa kwakajairika.Iyo inogadzirwa ne paste extrusion nzira.PTFE tubing inogadzirwa uchishandisa namira extrusion inochinjika uye inokwanisa kugadzira PTFE tubing ine mukati madhayamita madiki se 0.3 mm kusvika painodarika 100 mm uye ukobvu hwemadziro hudiki se0.1 mm kusvika 2 mm.Naizvozvo, polytetrafluoroethylene (PTFE) tubing chigadzirwa chakasiyana-siyana chinopa huwandu hwakasiyana hwekushandisa mumaindasitiri mazhinji akasiyana.
Nei PTFE machubhu achishandiswa zvakanyanya:
1. High tembiricha kuramba, insoluble mune chero solvent.Inogona kumira tembiricha yakakwira kusvika 300 ° C munguva pfupi, uye kazhinji inogona kushandiswa nguva nenguva pakati pe200 ° C uye 260 ° C, ine kugadzikana kwakanyanya kwekupisa.
2. Kudzikira kwekushisa kwekushisa, kusimba kwakanaka kwemagetsi pakudzika kwakadzika, kunyange kana kutonhora kuchidzika kusvika -65 ℃, haizove yakasvibiswa, uye inogona kuchengetedza 5% elongation.
3. Corrosion inopesana, inert kune akawanda makemikari uye zvinonyungudutsa, inopesana neakasimba acids uye alkalis, mvura uye zvakasiyana-siyana zvinonyungudutsa zvehupenyu, zvinogona kudzivirira zvikamu kubva kune chero rudzi rwemakemikari corrosion.
4. Anti-kuchembera, pasi pemutoro wakakwirira, ine mabhenefiti maviri ekudzivirira kupfeka uye kusanamatira.Hupenyu hwekuchembera hwakanakisa mumapurasitiki.
5. High lubrication, iyo yakaderera coefficient of friction pakati pezvinhu zvakasimba.Iyo coefficient of friction inoshanduka kana mutoro unotsvedza, asi kukosha kuri pakati pe0.05-0.15 chete.Naizvozvo, ine zvakanakira kuderera kwekutanga kuramba uye kushanda kwakatsetseka kwekugadzira mabearings.
6. Kusina-kunamatira ndiko kuderera kuduku kwepamusoro pezvinhu zvakasimba, uye hazvinamatira kune chero zvinhu.Zvinenge zvinhu zvese hazvibatike pazviri.Mafirimu akaonda kwazvo anoratidzawo zvinhu zvakanaka zvisina tsvimbo.
7. Haina kunhuwa, haina kunaka, haina chepfu, physiologically inert, uye haina maitiro akaipa kana yakasimwa mumuviri setsinga dzeropa uye nhengo kwenguva yakareba.
8. Kureruka uye kushanduka.Kuderedza zvakanyanya kusimba kwebasa remushandisi.
Mamwe mashandisirwo akajairika ePTFE machubhu:
1.Chemical Industry
Nekuda kwekukwirira kwavo kwemakemikari kuramba kune anenge ese makemikari, PTFE machubhu akanakira kushandiswa muindasitiri yemakemikari.Izvi zvinosanganisira semiconductor industry.Maitiro echizvino-zvino mukugadzira semiconductor anoda metering yakachengeteka uye kutakura kwezvinwiwa zvinoparadza (asidhi nemabhesi).Izvi zvinogona kukuvadza zvakanyanya chubhu yekutumira munguva pfupi.
2. Indasitiri yemotokari
Muinjini yemotokari, tubing yemhando yepamusoro yakagadzirwa nePTFE inoshandiswa pakunyudza kwemafuta uye njanji dzemafuta.Senge hosi dzemafuta, hosi dzeturbocharger, hosi dzinotonhorera, hosi dzemabhureki otomatiki, mabhureki emudhudhudhu, mapaipi einjini yedhiziri, hosi dzemujaho uye hosi dzemagetsi.Hunhu hwekushisa kwepamusoro uye kuderera kwekushisa kwekudzivirira, kupikisa kwepamusoro, kupfeka kusagadzikana uye kusagadzikana kwekuora kwePTFE tube inoita kuti ive nehupenyu hurefu hwebasa pasina kudzokororwa kakawanda.
3. Indasitiri yekudhinda ye3D
Mukudhinda kwe 3D, iyo filament inofanira kuendeswa kune inodhinda nozzle, iyo inofanirwa kuitwa muhupamhi hwekushisa.PTFE tubing ndiyo inonyanya kufarirwa polymer muindasitiri yekudhinda ye3D nekuda kwekukwira kwayo tembiricha coefficient uye isiri-tsvimbo zvivakwa, izvo zvinobatsira kutsvedza zvinhu zviri nyore kubva mumuromo.
4.Medical industry
Yakakosha zvimiro zvePTFE machubhu zvinosanganisirawo nyore-ku-kuchenesa nzvimbo yepasi.Mumakore gumi apfuura, PTFE tubing yave ichiwedzera kushandiswa mumidziyo yekurapa.Nekuda kweiyo yakaderera coefficient of friction yePTFE tubing, zvinoreva kuti ine nzvimbo yakatsetseka isingafukidze kana kubatsira kukura kwebhakitiriya.Pakati pavo, hoses inoshandiswa kune cannulas, catheters, pipettes uye endoscopes.
5. Indasitiri yezvokudya
Nekuda kwekuchenesa kwayo kuri nyore uye kusanamatira zvivakwa, PTFE tubing inogona kushandiswa muindasitiri yezvekudya.Kunyanya, machubhu akagadzirwa asina kuzadzwa PTFE akakodzera nekuda kwekusarerekera kwavo kwepanyama uye anoenderana neUS Food and Drug Administration nhungamiro.Nokudaro, yakaratidza kuti haina ngozi mukubatana nepurasitiki uye chero rudzi rwechikafu.
Kutenga iyo chaiyo PTFE tubing haisi yekungosarudza zvakasiyana siyana zvekushandisa zvakasiyana.Zvimwe kusarudza mugadziri akavimbika.Besteflon Fluorine plastic Industry Co., Ltd. inyanzvi mukugadzirwa kwemhando yepamusoro yePTFE hoses nemachubhu kwemakore gumi nemashanu.Kana paine mibvunzo uye zvinodiwa, ndapota inzwa wakasununguka kutibvunza kune mamwe mazano ehunyanzvi.
