Iimpawu zePTFE umatshini wokubumba.
1. Teflon umatshini wokubumba ozenzekelayo/ umatshini wokubumba we-tetrafluoro, ukusebenza ngobukrelekrele, iiyure ezingama-24 imveliso eqhubekayo inokufezekiswa.
2. Ukulayishwa ngokuzenzekelayo, ukushisa kweoli, izinto eziphathekayo, ukujonga kwangexesha langempela ukusebenza kwesebe ngalinye lezixhobo, umsebenzi wokubeka iliso kude uyafumaneka, kwaye ipleyiti yeyadi yengalo yomatshini ibekwe kakuhle.
3. Iyakwazi ukwenza ngokuzenzekelayo ibha, umbhobho, iinxalenye ezibunjiweyo, ezixhotywe ngeentlobo ezahlukeneyo zokubumba, umatshini omnye onama-molds amaninzi kunye namacandelo amaninzi, umbhobho unokufezekisa ubuninzi bodonga lwe-2mm.impazamo yokuphakama kwamalungu abunjiweyo anokulawulwa kwi-± 0.02mm.
Intshayelelo yemveliso.
I-Polytetrafluoroethylene ngokuqhelekileyo yaziwa ngokuba yi-tetrafluoro, iTeflon, iKumkani yePlastiki, iTeflon, kunye nomatshini wokubumba ngumatshini okhethekileyo wokubumba iimveliso ze-polytetrafluoroethylene.Impahla ekrwada ye-PTFE powder iyabunjwa, ifudunyezwe kwaye ipholiswe ngoluhlu lokucutshungulwa sisixhobo sokuvelisa iimveliso ezibunjiweyo ezihambelana neenkcukacha ezahlukeneyo.Ngokuxhomekeke kwisicelo, ukucaciswa, izithako, iimfuno zomsebenzisi kunye nezinye izinto ezinxulumene nazo, iinkcukacha ezahlukeneyo zomatshini wokubumba zingayilwa kwaye ziveliswe.Iimveliso ze-PTFE eziveliswayo zisetyenziswa ngokubanzi kwiikhemikhali, i-aerospace, izixhobo zoomatshini, utshintshiselwano lobushushu kunye nezinye iindawo.
Inkqubo yokubumba i-ptfe
Inkqubo yokubumba i-ptfe yeyona ndlela isetyenziswa kakhulu.Ukubumba kwe-PTFE kungasetyenziselwa ukusetyenzwa kweepleyiti, iintonga, imikhono, iiteyiphu, imisesane yokutywina, iidiaphragms, kunye neenxalenye ezineentsimbi zentsimbi.
Indlela yokubumba ye-ptfe iqulathe amanyathelo amane: ukuxuba, ukwenza kwangaphambili, ukupholisa, kunye nokupholisa.Ukulungisa kwangaphambili yinkqubo yokongeza i-ptfe powder ngokulinganayo kwisingundo kwaye uyicinezele kwi-preform eshinyeneyo (okt, engenanto) kwiqondo lokushisa;i-sintering yinkqubo yokufudumeza i-preform ngaphezu kwendawo yokunyibilika kunye nokupholisa yinkqubo yokunciphisa ubushushu be-sintering kwiqondo lokushisa.
Enye i-ptfe icinezelwe kanye phezu kobushushu beqondo lokunyibilika, olu ngundo lokubumba, olubizwa ngokuba ngumngundo ocinezelayo oshushu, ngolu hlobo lokungunda oluhambelanayo lwe-PTFE lubizwa ngokuba ngumngundo ocinezelayo obandayo.
Xa ptfe ukubumba kufuneka ingqalelo umlinganiselo ukunyanzeliswa (a Yin PTFE for 4-6) kunye nokubumba ukushwabana (ngokubanzi PTFE for 2.6-4.5%) kwimpembelelo imveliso.
Izinto ezingcono kakhulu eziluhlaza kunye ne-suspension polymerization resin, ubungakanani be-particle ye-20-500 microns ye-powder epholileyo ekhululekile iyona nto ingcono.Inkqubo yokucinezela kufuneka "ihlanjululwe", i-pre-forming pressure ye-17-35 MPa, ukubamba ixesha ngokuhambelana nobukhulu be-blank, njenge-100 mm engenanto, kufuneka ibambe uxinzelelo lwemizuzu eyi-15.
