Ptfe filimu processing zida adzagwiritsa ntchito Isostatic akamaumba Machine, Isostatic Kuumba Machine kapamwamba kupanga, ndiyeno sintering, potsiriza ntchito Skiving Machine kwa Skiving.Ptfe mafilimu makamaka anawagawa mitundu iwiri: microporous filimu ndi kutembenukira film.The kusiyana kwakukulu pakati pa awiriwa. ndi permeability wa microporous nembanemba, amene amapangidwa ndi biaxial kutambasula.Kutembenuza filimu amadulidwa mu lathe, si kupuma.
Ptfe filimu processing zida adzagwiritsa ntchito Isostatic akamaumba Machine, Isostatic Kuumba Machine kapamwamba kupanga, ndiyeno sintering, potsiriza ntchito Skiving Machine kwa Skiving.
Mafilimu a Ptfe amagawidwa m'mitundu iwiri: filimu ya microporous ndi kutembenuza filimu.Kusiyana kwakukulu pakati pa ziwirizi ndi kutsekemera kwa nembanemba ya microporous, yomwe imapangidwa ndi biaxial stretching.Kutembenuza filimu kumadulidwa kuchokera ku lathe, sikupuma.
Ine sindikudziwa za kutembenuza filimu, mukudziwa kuti ayenera kugwiritsidwa ntchito pa chisindikizo more.We tikulankhula za microporous nembanemba.
Polytetrafluoroethylene (ptfe) microporous filimu amapangidwa ndi polytetrafluoroethylene utomoni particles, amene kukodzedwa ndi anatambasula kupanga microporous filimu.Ikhoza kugawidwa m'magulu otsatirawa:
1. Nembanemba yosefera mpweya
Polytetrafluoroethylene nembanemba angagwiritsidwe ntchito mumlengalenga fumbi kuchotsa, kuyeretsedwa mpweya ndi zina zotero nembanemba pore kukula akhoza lizilamulira 0,2 um, porosity akhoza kufika oposa 88%, ndi singano anamva, limagwirira la nsalu, sanali nsalu nsalu, galasi CHIKWANGWANI ndi zinthu zina zosefera zokhala ndi gawo lophatikizika losefera la nsalu zokutira, PTFE zokutira zosefera zili ndi mphamvu zambiri za peel, voliyumu ya mpweya, kukula kwa pore, etc. idzawerengedwa mwachangu komanso moyenera kuwerengera ndi fumbi laling'ono kwambiri, fumbi lochotsa fumbi lingafikire kuposa 99.99%, moyo wautumiki kwa zaka zitatu, mpweya wabwino wa 3-6 m / min, pano ndiye kusefera kwapamwamba kwambiri padziko lonse lapansi. zakuthupi, zotsukira zamitundu yonse, zosefera mpweya, zida zoyeretsera mpweya, chisankho chabwino kwambiri cha fyuluta ya mpweya wabwino kwambiri, etc.
Ma parameter aukadaulo ndi awa:
makulidwe: 5-15 mm
Kuthekera kwa mpweya: 80-100l /㎡•s
M'lifupi: 1800 mm kapena kuchepera
Kukaniza: pa 80 kapena kuchepera
Kuchita bwino: 99.99%
2. Madzi ndi chinyezi-permeable microporous nembanemba
Ptfe madzi chinyezi permeable microporous nembanemba amapangidwa ndi kuvomerezedwa ndi ndondomeko yapadera bidirectional kumakoka nembanemba pamwamba pa lalikulu inchi akhoza kufika mabiliyoni a microporous, aliyense pore awiri (0.5 kuti 0.1 um um) ndi zosakwana mamolekyu osachepera madzi mu nkhungu wa mtengo osachepera (20 UN um - 100), m'mimba mwake wamkulu kuposa madzi nthunzi mamolekyu (0.0004 kuti 0.0003 um um), nthunzi m'madzi, ndipo sangathe kudutsa, kutenga mwayi microporous dongosolo angakwanitse kwambiri madzi ndi chinyezi. permeable ntchito; Komanso, chifukwa dzenje ndi laling'ono kwambiri ndi longitudinal kusakhazikika kupinda makonzedwe, kotero kuti mphepo sangadutse, ndipo motero ali ndi chitetezo mphepo ndi kuteteza kutentha makhalidwe. pa filimu ya PTFE, kufulumira kwake ndi kulimba kwake kunakula kwambiri, pambuyo pophatikizika ndi nsalu zina, zomwe zimagwiritsidwa ntchito kwambiri mu zovala za greenwood, zovala zachipatala, zovala zopuma, kuwongolera moto, kuteteza mankhwala, antivayirasi, ntchito ya kusefukira kwa madzi, monga zovala zapadera zotetezera, masewera akunja. zovala, nsapato ndi zipewa, magolovesi ndi zipangizo zina komanso zikwama zogona, mahema ndi zipangizo zina
Ma parameter aukadaulo ndi awa:
makulidwe: 20-50 mm
Chinyezi permeability: 16000g/㎡•24hr
Kuthamanga kwa Hydrostatic: 6000mm
Kukana kwakukulu kwa UV: 97 apamwamba kwambiri
M'lifupi: 1700 mm kapena kuchepera
G: 5-10 g/m2
3. polima kuwira mfundo filimu
Ndi polytetrafluoroethylene (ptfe) monga zopangira, pambuyo kudzitukumula Tambasula kupanga mtundu wa nembanemba microporous, nembanemba ndi ndondomeko yapadera pamodzi pa mitundu yonse ya nsalu ndi zinthu m'munsi, kukhala mtundu watsopano wa zinthu kusefera, nembanemba pore kukula ndi yaying'ono, pafupifupi 0,2 mpaka 0.5 mu m, kugawa yunifolomu, porosity, ndikusunga kufalikira kwa mpweya, imatha kusefa tinthu tating'onoting'ono ta fumbi, kuphatikiza mabakiteriya, kukwaniritsa cholinga cha kuyeretsedwa ndi mpweya wabwino, kumagwiritsidwa ntchito kwambiri muzamankhwala, zamankhwala, zamankhwala, ma microelectronics. ndi ma laboratory consumables, etc.
Zosintha zaukadaulo:
Makulidwe kuwira mfundo
1600mm ≥1kg/cm2 (5.3m/s 127Pa)
