Qalabka wax lagu sameeyo ee Ptfe wuxuu isticmaali doonaa Mashiinka wax-qabashada ee Isostatic, Bar-soo-saarka Mashiinka Wax-soo-saarka, ka dibna sintering, ugu dambeyntii isticmaalaya Machine Skiving for Skiving. Filimada Ptfe waxaa inta badan loo qaybiyaa laba nooc: filim microporous iyo film jeestay. Farqiga ugu weyn ee u dhexeeya labada waa qulqulka xuubka microporous, kaas oo ay soo saarto iskala-xinjirow biaxial ah
Qalabka farsamaynta filimada ee Ptfe waxay isticmaali doonaan Mashiinka wax-qabashada ee Istatic, Bar-soo-saarka Mashiinka Wax-qabashada ee Isostatic, ka dibna isku-buufinaya, ugu dambeyntiina isticmaalaya Mashiinka Skiving for Skiving.
Filimada Ptfe inta badan waxay u qaybsan yihiin laba nooc: filim microporous iyo film jeestay. Farqiga ugu weyn ee u dhexeeya labada waa permeability ee xuubka microporous, kaas oo ay soo saartaa iskala biaxial. Film-rogid ayaa laga gooyay ee lathe, ma neefsato.
Ma aqaano filimka soo-rogista, ogow in loo isticmaalo shaabadda in ka badan. Waxaan ka hadlaynaa xuubabka microporous.
Polytetrafluoroethylene (ptfe) filimka microporous wuxuu ka samaysan yahay walxaha polytetrafluoroethylene, kaas oo la ballaariyay oo la fidiyay si loo sameeyo filim microporous.Waxa loo qaybin karaa qaybaha soo socda:
1. Xuub sifaynta hawada
Xuubabka Polytetrafluoroethylene waxaa loo isticmaali karaa ka saarista boodhka atmospheric, nadiifinta hawada iyo wixii la mid ah cabbirka daloolka xuubka waxaa lagu xakameyn karaa 0.2 um, porosity wuxuu gaari karaa in ka badan 88%, iyo irbaddu waxay dareemeysaa, habka maro, dhar aan duubnayn, fiber galaas iyo walxaha kale ee filtarrada leh wejiga shaandhaynta waxqabadka shaandhaynta wejiga isku dhafan ee dharka dahaarka leh, wax shaandhaynta dahaarka leh ee PTFE waxay leedahay xoogga diirka sare, mugga hawada, qaybinta cabbirka daloolada labiska, iwm. si dhakhso leh oo hufan ayaa loo xisaabin doonaa dhexda micron ultra wanaagsan boodh, hufnaanta ka saarista boodhka waxay gaari kartaa in ka badan 99.99%, nolosha adeegga saddex sano, heerka hawo ilaa 3-6 m/min, hadda waa shaandhaynta hawada ugu horumarsan adduunka. alaabta, dhammaan noocyada kala duwan ee nadiifiyaha vacuum, filter hawada, qalabka sifaynta hawada, doorashada ugu fiican ee hufnaan sare filter hawada, iwm
Halbeegyada farsamada waa sida soo socota:
Dhumucda: 5 um - 15 um
Dhererka hawada: 80-100l /㎡•s
Ballaca: 1800 mm ama ka yar
Resistance: pa 80 ama ka yar
Waxtarka: 99.99%
2. Xuub microporous oo aan biyuhu lahayn iyo qoyaan-dalool
Ptfe xuubka microporous qoyaanka daadi kara waxaa la sameeyay oo ansixiyay hab gaar ah xuubka xajinta labajibaaran yahay halkii inch oo labajibbaaran wuxuu gaari karaa balaayiin microporous ah, dhexroor kasta oo dalool ah (0.5 ilaa 0.1 um um) waa ka yar yahay molecules biyaha ugu yar ee ceeryaamo Qiimaha ugu yar (20 UN um - 100), dhexroorka ka weyn molecules uumiga biyaha (0.0004 ilaa 0.0003 um um), uumiga biyaha dhex mara biyaha, oo aan dhaafi karin, ka faa'iidayso qaab-dhismeedka microporous gaari karaa biyo-ilaacin aad u fiican iyo qoyaan. function permeable; Intaa waxaa dheer, sababtoo ah dalool waa mid aad u yar iyo habayn foorarsi aan joogto ahayn longitudinal, si aanay dabayshu u dhex mari karin, oo sidaas daraaddeed waxay leedahay ilaalinta dabaysha wanaagsan iyo sifooyinka ilaalinta kulaylka.Tan iyo imaatinka xuubka iyada oo hagaajin joogto ah, daaweyn gaar ah. on filimka PTFE, xawligeeda iyo cimri dhererkeeda si weyn ayaa loo hagaajiyay, ka dib markii la isku daro dhar kale, oo si ballaaran loo isticmaalo dharka cagaaran, dharka caafimaadka, dharka madadaalada, xakamaynta dabka, ilaalinta kiimikada, antivirus, hawlgalka daadadka, sida dharka ilaalinta gaarka ah, ciyaaraha dibadda dharka, kabaha iyo koofiyadaha, galoofyada iyo qalabyada kale iyo sidoo kale bacaha lagu seexdo, teendho iyo agab kale
Halbeegyada farsamada waa sida soo socota:
Dhumucda: um 20-50 um
Dhererka qoyaanka: 16000g/㎡•24hr
Cadaadiska Hydrostatic: 6000mm
UV caabbinta daran: 97 ugu sarreeya
Ballaca: 1700 mm ama ka yar
G: 5-10 g/m2
3. filim dhibic xumbo polymer
Waxay la polytetrafluoroethylene (ptfe) sida alaabta ceeriin, ka dib markii fidinta fidsan samaynta nooc ka mid ah xuub microporous, xuubka leh hab gaar ah oo lagu daray dhammaan noocyada kala duwan ee dhar iyo alaabta saldhigga, noqdaan nooc cusub oo sifaynta, size dalool xuub waa. yar, oo ku saabsan 0.2 si ay u 0.5 m, qaybinta uniform, porosity, iyadoo la ilaalinayo wareegga hawada, shaandhayn karaa dhammaan qaybaha boodhka, oo ay ku jiraan bakteeriyada, gaadho hadafka nadiifinta sare iyo hawo, waxaa si ballaaran loo isticmaalaa in farmashiyaha, biochemical, microelectronics. iyo alaabta shaybaadhka, iwm.
