PTFE Processing da Aikace-aikace

MenenePTFE?

Bari mu fara bincikar menene ainihin PTFE.Don ba shi cikakken take, polytetrafluoroethylene shine polymer roba wanda ya ƙunshi abubuwa biyu masu sauƙi;carbon da fluorine.An samo shi daga tetrafluoroethylene (TFE) kuma yana da wasu kaddarorin na musamman waɗanda suka sa ya zama abu mai amfani a cikin aikace-aikace masu yawa.Misali:

Matsayin narkewa sosai: Tare da wurin narkewa na kusa da 327 ° C, akwai yanayi kaɗan da zafi zai lalata PTFE.

Hydrophobic: Juriya ga ruwa yana nufin ba ya jika, yana sa ya zama mai amfani a dafa abinci, suturar rauni da ƙari.

Kemikal inert: Mafi yawan kaushi da sinadarai ba za su lalata PTFE ba.

Low coefficient na gogayya: Ƙididdigar juzu'i na PTFE ɗaya ne daga cikin mafi ƙasƙanci na kowane ƙarfi a wanzuwa, ma'ana babu abin da zai manne da shi.

Ƙarfin ƙwanƙwasa: Ƙarfin lanƙwasa da lanƙwasa, ko da a ƙananan zafin jiki, yana nufin ana iya amfani da shi cikin sauƙi a wurare daban-daban ba tare da rasa amincinsa ba.

Farashin PTFE

Ana iya samun PTFE a cikin granular, watsawa da foda mai kyau.Semi-crystalline PTFE yana da babban narkewa zafin jiki da kuma narke danko, yin hankula extrusion da allura gyare-gyaren wuya.sarrafa PTFE, don haka, ya fi kama da sarrafa foda fiye da na robobi na gargajiya.

An samar da PTFE na granular a cikin abin da aka dakatar da shi na tushen ruwa.Sakamakon resin granular galibi ana sarrafa su zuwa siffa ta hanyar gyare-gyaren gyare-gyare.Ana samar da samfuran watsawa na PTFE a cikin irin wannan hanya, tare da ƙarin wakilai masu rarrabawa.Ana iya amfani da samfuran watsawa don suturar PTFE ko ana iya sarrafa su a cikin fim na bakin ciki ta hanyar simintin fim.Ana samar da foda na PTFE a cikin emulsion polymerisation dauki.A sakamakon lafiya foda za a iya manna extruded cikin PTFE kaset, PTFE tubing, da waya rufi, ko amfani da a matsayin ƙari ƙara lalata juriya a wasu polymeric kayan.

Manyan Aikace-aikace 5 na PTFE

1. Aikace-aikace na anti-lalata Properties

Rubber, gilashi, gami da ƙarfe da sauran kayan sun kasa saduwa da matsananciyar yanayi na yanayin zafi, matsa lamba da muhallin haɗin gwiwar kafofin watsa labarai saboda lahaninsu na juriya na lalata.Duk da haka, PTFE yana da kyakkyawan juriya na lalata kuma don haka ya zama babban kayan juriya na lalata don man fetur, sinadarai, yadi da sauran masana'antu.

2. Aikace-aikace na ƙananan gogayya Properties a cikin kaya

Lubrication na mai bai dace da sassan sassa na wasu kayan aiki ba, saboda ana iya narkar da maiko ta hanyar kaushi kuma ba ya aiki, ko samfuran da ke cikin magunguna, abinci, yadi da sauran filayen masana'antu suna buƙatar guje wa tabo ta lubricants.Sakamakon haka, filastik PTFE, wanda ƙimar juzu'in sa ya fi kowane sanannen ingantaccen abu, ya zama mafi kyawun abu don lubrication mara amfani (ɗaukar nauyin kai tsaye) na sassan kayan aikin injiniya.

3. Aikace-aikace a cikin lantarki da lantarki

Ƙarƙashin ƙarancin hasara da ƙananan dielectric akai-akai na kayan PTFE yana ba da damar yin kanta ta zama waya mai enameled don ƙananan motoci, thermocouples da na'urorin sarrafawa.Fim ɗin PTFE shine mafi kyawun kayan rufewa don masana'anta capacitors, layin rufin rediyo, igiyoyin kebul, injina da masu canji, kuma yana ɗaya daga cikin abubuwan da ba a buƙata don sararin samaniya da sauran abubuwan lantarki na masana'antu.

4. Aikace-aikace a likitancin likita

Expanded PTFE ne zalla inert kuma sosai nazarin halittu adaptable, don haka shi ba ya haifar da kin amincewa da jiki, ba shi da physiological illa a jikin mutum, za a iya haifuwa ta kowace hanya, kuma yana da Multi-microporous tsarin.

5. Aikace-aikace na anti-adhesive Properties

Tare da mafi ƙasƙanci tashin hankali na kowane abu mai ƙarfi, PTFE Teflon baya tsayawa ga kowane abu.Bugu da ƙari, yana da kyakkyawan juriya ga yanayin zafi da ƙananan zafi.A sakamakon haka, an yi amfani da shi sosai a cikin yanayin anti-manne na kwanon rufi ba tare da sanda ba.
