Iifilimu ze-Ptfe zihlulwe kakhulu zibe ziintlobo ezimbini: ifilimu ye-microporous kunye nefilimu ejikayo.Umehluko omkhulu phakathi kwezi zibini yi-permeability ye-membrane ye-microporous, eveliswa yi-biaxial stretching.Ifilimu yokuguqula inqunyulwe ngaphandle kwe-lathe, ayiphefumli.
Andazi malunga nokujika ifilimu, yazi ukuba kufuneka isetyenziswe kwitywina ngaphezulu.Siza kuthetha ngeenwebu ezincinci.
Ifilimu ye-Polytetrafluoroethylene (ptfe) ifilimu ye-microporous yenziwe nge-polytetrafluoroethylene resin particles, eyandisiweyo kwaye yoluliwe ukuze yenze ifilimu ye-microporous.Inokwahlulwa ngokwezi ndidi zilandelayo:
1. I-membrane yokucoca umoya
Polytetrafluoroethylene inwebu ingasetyenziselwa ukususwa uthuli emoyeni, ukuhlanjululwa umoya kwaye njalo kwi inwebu ubungakanani pore inokulawulwa 0.2 um, porosity inokufikelela ngaphezu kwama-88%, kunye inaliti waziva, indlela ilaphu, ilaphu non-elukiweyo, ifayibha yeglasi kunye ezinye izinto zokucoca kunye nesigaba somphezulu sokucoca ukucoca kwelaphu eligqunyiweyo, i-PTFE icwecwe izinto zokucoca zinamandla aphezulu e-peel, umthamo womoya, ukusabalalisa ubungakanani bepore efanayo, njl. iya kubalwa ngokukhawuleza nangokufanelekileyo i-intercept kunye nothuli olucolekileyo lwe-micron, ukusebenza kakuhle kokususa uthuli kunokufikelela ngaphezu kwe-99.99%, ubomi benkonzo iminyaka emithathu, izinga lokungena komoya ukuya kuthi ga kwi-3-6 m / min, okwangoku lolona hluzo lomoya oluphambili kwihlabathi. Izinto eziphathekayo, zonke iintlobo zokucoca umoya, isihluzi somoya, izixhobo zokucoca umoya, olona khetho lulungileyo lokucoca umoya, njl.
Iiparamitha zobugcisa zimi ngolu hlobo lulandelayo:
Ukutyeba: 5 um – 15 um
Ukungena komoya: 80-100l /㎡•s
Ububanzi: 1800 mm okanye ngaphantsi
Ukumelana: pa 80 okanye ngaphantsi
Ukusebenza kakuhle: 99.99%
2. I-membrane ye-microporous engangeni manzi kunye nomswakama
Ptfe ukufuma manzi permeable inwebu microporous yenziwa kwaye kuvunywe inkqubo ekhethekileyo bidirectional tensile inwebu umphezulu intshi nganye isikwere inokufikelela kwiibhiliyoni microporous, i pore nganye ububanzi (0.5 ukuya 0.1 um um) ingaphantsi kobuncinane beemolekyuli zamanzi kwinkungu ixabiso elincinci (20 UN um - 100), ububanzi obukhulu kuneemolekyuli zomphunga wamanzi (0.0004 ukuya ku-0.0003 um um), umphunga wamanzi emanzini, kwaye awukwazi ukudlula, uthathe inzuzo yesakhiwo se-microporous unokufikelela ngokugqwesileyo kwamanzi kunye nokufuma. umsebenzi permeable;Ukongezelela, ngenxa yokuba umngxuma incinci kakhulu kwaye longitudinal ilungiselelo ukugoba ngokungaqhelekanga, ukuze umoya awukwazi ukudlula, kwaye ngaloo ndlela unokhuseleko lomoya olungileyo kunye neempawu zogcino lobushushu.Ukusukela ekufikeni kwenwebu ngokuphuculwa okuqhubekayo, unyango olukhethekileyo. kwifilimu ye-PTFE, ukukhawuleza kwayo kunye nokuqina kwayo kuphuculwe kakhulu, emva kokudibanisa kunye nezinye iingubo, ezisetyenziswa ngokubanzi kwiingubo ze-greenwood, iimpahla zonyango, iimpahla zokuzonwabisa, ukulawula umlilo, ukukhusela iikhemikhali, i-antivirus, ukusebenza kwezikhukula, njengempahla ekhethekileyo yokukhusela, imidlalo yangaphandle. iimpahla, izihlangu kunye neminqwazi, iiglavu kunye nezinye izixhobo kunye neengxowa zokulala, iintente kunye nezinye izinto
Iiparamitha zobugcisa zimi ngolu hlobo lulandelayo:
Ukutyeba: um 20-50 um
Ukufuma ukufuma: 16000g/㎡•24hr
Uxinzelelo lweHydrostatic: 6000mm
Ukuchasa okugqithisileyo kwe-uv: i-97 ephezulu
Ububanzi: 1700 mm okanye ngaphantsi
G: 5-10 g/m2
3. ifilimu ye-polymer bubble point
Yona kunye ne-polytetrafluoroethylene (ptfe) njengento ekrwada, emva kokukhukhumala ukolula ukwenza uhlobo lwenwebu encinci, inwebu enenkqubo ekhethekileyo edityaniswe nazo zonke iintlobo zelaphu kunye nesiseko sezinto, iba luhlobo olutsha lwezinto zokuhluza, ubukhulu be-membrane pore encinci, malunga ne-0.2 ukuya kwi-0.5 mu m, ukusabalalisa okufanayo, i-porosity, ngelixa igcina ukujikeleza komoya, inokucoca zonke iincinci zothuli, kuquka iibhaktheriya, zifezekise injongo yokuhlanjululwa okuphezulu kunye nokuphuma komoya, isetyenziswa ngokubanzi kwi-pharmaceuticals, biochemical, microelectronics. kunye nezinto ezisetyenziswa kwilabhoratri, njl.
Imilinganiselo yobugcisa:
Indawo yeqamza yobubanzi obutyebileyo
1600mm ≥1kg/cm2 (5.3m/s 127Pa)
