Nokufamba kwemakore,PTFE coatingsarudzo dzakakura mumusika wemidziyo yekurapa, zvichivandudza maitiro ekugadzira nenzira dzakawanda dzakasiyana.Uye nezvakawanda zvezvishandiso uye sarudzo dzekupfeka dziripo nhasi, kusarudza iyo chaiyo yakashongedzwa mandrel kune yako yakasarudzika yekugadzira zvinodiwa inogona kutaridzika zvakanyanya kuomarara.Naizvozvo, hezvino zvinhu zvishanu zvekufunga nezvazvo pakusarudza mandrel yakavharwa kuti sarudzo yako ive nyore.
1. Funga uchidzokera shure
Chekutanga, funga kuti chinangwa chikuru chekupedzisira-kushandisa application uye michina chii.Kunyangwe iwe uri kuvaka iyo yepamusoro yekufambisa sisitimu ine akawanda lumens kana extruding pane akawanda-tapered mandrel.Kunzwisisa kuti chigadzirwa chekupedzisira chichashandiswa sei kuchakubatsira kuti uone akakosha maitiro anodiwa kune akavharwa mandrels.
2. Nyora pasi
Nyora pasi marudzi ese uye kuoma kwemapolymers anodiwa kuti asangane neproximal uye distal shaft kuita zvinodiwa, senge kink kuramba uye maneuverability.Izvo zvakakoshawo kuti unzwisise kuti tembiricha yekushanda yeiyo reflow process inobata sei imwe neimwe polymer.Somuenzaniso, zvimwePTFEmabhachi anokwanisa kushingirira tembiricha isingaperi ye550°F uye anogona kumira tembiricha ye700°F.
3. Edza zvaunogona kuita
Zvino zvawasarudza tembiricha yaunogona kushandisa, iwe unofanirwa kufunga nezve mandrel base zvinhu zvekushandisa.Kunyange paine mari yekuchengetera mari inofanirwa kuitwa kana uchifunga nezvechimwe chinhu pamusoro peimwe, iwe unofanirwa kufunga nezvezvinhu zvivakwa uye zvakanakira izvo zvega mandrel zvinhu zvinopa mukugadzira maitiro.Zvinogona kubatsira kutsvaga vatengesi vanogona kupa huwandu hwakawanda hweakashongedzwa arbor substrates senge simbi isina tsvina, Nitinol, uye sirivha-yakapfatwa mhangura.Iwe unogona ipapo kuyedza yega mandrel zvinhu kuti uone yakanakisa yekushandisa kwako uye bhajeti.Nzira yakanakisa yekuita sarudzo iyi ndeyekuyedza sarudzo dzako.
4. Sarudza zvinodiwa lubricity
Kuona izvo zvinodikanwa zve lubricity zvichabatsira kuve nechokwadi chekuti nzira yekupfekedza inowana hupenyu hurefu hwemandrel panguva yekugadzira.Iwo mawaya ekudhonza uye magiraidhi anoshandiswa mukupindira maitiro anofanirwa kupfuura zvisina musono kuburikidza nepakati dhayamita yecatheter, saka yemhando yepamusoro yekuzora senge.PTFE zvinhuinofanira kushandiswa.zvimwe zvakasiyana-siyana zvePTFE fluoropolymer coatings, zvakadai sePTFE Natural, inogona kupa mabhenefiti ekuita.Semuyenzaniso, coefficient of friction of 0.05 inowanikwa kurerutsa catheter kubviswa panguva yefuse welding nekudurura mashandiro.
5. Key coating properties kutsvaga
Chekupedzisira, kunyangwe iwe uri kugadzira mutsara wekudhonza kana conveyor system, gara uchitsvaga mhando-yakavharwa mandrel ine yunifomu, chaiyo, isina-inobhururuka.
Sezvo kuomarara kunowedzera uye saizi yechigadzirwa ichidzikira, machira ane lubricious senge PTFE zvinhu zvinowedzera kukosha kune catheter yekugadzira maitiro.Kugara kwakakosha zvakare kuti uve nechokwadi chekuchengetedza uye kuita kwechero chikamu chinosanganisirwa mumidziyo yekupedzisira.
