1. Yin TFE

2.Suspension Polymerization

3.Dispersion polymerization

Farashin TFE

1 Masu kera PTFE suna farawa ta hanyar haɗa TFE.Sinadaran guda uku na TFE, fluorspar, hydrofluoric acid, da chloroform an haɗe su a cikin ɗaki mai zafi mai zafi zuwa tsakanin 1094-1652°F (590-900°C).Sakamakon iskar gas ɗin yana sanyaya, kuma a distilled don cire duk wani ƙazanta.

Dakatar da Polymerization

2 Gidan amsawa yana cike da ruwa mai tsafta da wakili ko mai ƙaddamarwa, wani sinadari wanda zai kashe samuwar polymer.Ana busa TFE ruwa a cikin ɗakin amsawa.Yayin da TFE ke saduwa da mai farawa, ya fara yin polymerize.Sakamakon PTFE yana samar da tsayayyen hatsi waɗanda ke iyo zuwa saman ruwa.Yayin da wannan ke faruwa, ɗakin amsa yana girgiza da inji.Halin sinadaran da ke cikin ɗakin yana ba da zafi, don haka ɗakin yana sanyaya ta hanyar zagayawan ruwan sanyi ko wani abin sanyaya a cikin jaket a kusa da waje.Gudanarwa ta atomatik yana kashe samar da TFE bayan an kai wani nauyi a cikin ɗakin.Ruwan yana zubewa daga ɗakin, yana barin ɓarna na PTFE mai ɗanɗano wanda yayi kama da ɗan kwakwa.

3 Bayan haka, an bushe PTFE kuma ana ciyar da shi a cikin injin niƙa.Niƙa yana jujjuya PTFE tare da ruwan wukake mai juyawa, yana samar da wani abu tare da daidaiton gari na alkama.Wannan foda mai kyau yana da wuyar ƙirƙira.Yana da "rashin talauci," ma'ana ba za a iya sarrafa shi cikin sauƙi a cikin kayan aiki na atomatik ba.Kamar garin alkama da ba a siffa ba, yana iya samun kullutu da aljihunan iska.Don haka masana'antun suna canza wannan foda mai kyau zuwa manyan granules ta hanyar da ake kira agglomeration.Ana iya yin hakan ta hanyoyi da yawa.Hanya ɗaya ita ce a haɗa foda na PTFE tare da sauran ƙarfi kamar acetone kuma a jefa shi a cikin ganga mai juyawa.Kwayoyin PTFE suna manne tare, suna samar da ƙananan pellets.Ana bushe pellet ɗin a cikin tanda.

4 Ana iya ƙera pellet ɗin PTFE zuwa sassa ta amfani da dabaru iri-iri.Koyaya, ana iya siyar da PTFE da yawa da aka riga an riga an tsara shi cikin abin da ake kira billlets, waɗanda ke da ƙarfi na PTFE.Billet ɗin na iya zama tsayin ƙafa 5 (1.5m).Ana iya yanke waɗannan a cikin zanen gado ko ƙananan tubalan, don ƙarin gyare-gyare.Don samar da billet, PTFE pellets ana zuba a cikin silinda bakin karfe mold.Ana ɗora ƙirar a kan maballin ruwa, wanda wani abu ne kamar babban majalisar da aka sanye da rago mai nauyi.Ragon yana faɗuwa cikin ƙirar kuma yana yin ƙarfi akan PTFE.Bayan wani lokaci, ana cire mold daga latsawa kuma PTFE ba a tsara shi ba.Ana ba da izinin hutawa, sannan a sanya shi a cikin tanda don mataki na ƙarshe da ake kira sintering.

5 Ana yin zafi da PTFE ɗin da aka ƙera a cikin tanda na tsawon sa'o'i da yawa, har sai ya kai ga zafin jiki na kusan 680°F (360°C).Wannan yana sama da wurin narkewa na PTFE.Barbashi na PTFE sun haɗu kuma kayan sun zama gel-kamar.Sa'an nan kuma PTFE ana sanyaya a hankali.Za a iya aikawa da kuɗin da aka gama zuwa ga abokan ciniki, waɗanda za su yanki ko aske shi cikin ƙananan guda, don ƙarin sarrafawa.

polymerization watsawa

6 Polymerization na PTFE ta hanyar watsawa yana haifar da ko dai lafiya foda ko wani abu mai kama da manna, wanda ya fi amfani ga sutura da ƙarewa.Ana shigar da TFE a cikin injin mai cike da ruwa tare da sinadari mai farawa.Maimakon a girgiza da ƙarfi, kamar a cikin tsarin dakatarwa, ɗakin amsawa yana tada hankali ne kawai.PTFE ya zama ƙananan beads.Ana cire wasu daga cikin ruwan, ta hanyar tacewa ko kuma ta hanyar ƙara sinadarai wanda ke haifar da beads na PTFE.Sakamakon abu ne mai madara mai suna PTFE watsawa.Ana iya amfani dashi azaman ruwa, musamman a aikace-aikace kamar masana'anta ya ƙare.Ko kuma za a iya bushe shi ta zama lallausan foda da ake amfani da ita don shafa ƙarfe
