PTFE, FEP nePFA ndiwo ma fluoroplastic anozivikanwa zvikuru uye akajairika. Asi musiyano wavo ndeupi chaizvo? Tsvaga kuti nei ma fluoropolymer ari zvinhu zvakasiyana, uye kuti ndeapi ma fluoroplastic akakodzera kushandiswa kwako.
Hunhu hwakasiyana hwe fluoroplastics
MaFluoropolymers ane hunhu hwakasiyana hunoita kuti akwanise kushandiswa mukurapa, mumotokari, mumagetsi uye mudzimba, pakati pezvimwe.
Fluoroplastics ine zvinhu zvinotevera:
1.Very tembiricha yekushanda yakakwira
2. Hunhu husina kunamira
3.Kukweshana kwakaderera pamusoro
4.Kuramba kwakanyanya kumakemikari uye zvinonyungudutsa
5.Kudzivirira kwemagetsi kwakanyanya kwazvo
Mapurasitiki akasiyana-siyana ane misiyano mishoma, kusanganisira tembiricha dzakasiyana dzekushanda, uye akakodzera kushandiswa kwakasiyana. Kana akasarudzwa nemazvo, mapolymers efluoropolymer anogona kupa mitengo yakanaka uye mabhenefiti ekushanda zvakanaka.
Mabhenefiti ePTFE
PTFE, kana kuti Polytetrafluoroethylene, ndiyo sekuru wezvese fluoroplastics. Yakawanikwa nesainzi Roy J. Plunkett muna 1938, PTFE ndiyo fluoropolymer isingawanzoitiki uye inoratidza kushanda kwakanakisisa maererano nekupisa, kuramba makemikari uye hunhu husina kunamira.
Pamusoro pekunakidzwa nehunhu hwakasiyana hwe fluoroplastics, PTFE inozvisiyanisa nekuva nemabhenefiti anotevera:
1. Mutengo wakanakisisa: chiyero chekushanda
2. Kupisa kunoshanda nguva dzose kwe +260°C - Uku ndiko kupisa kwakanyanya kushanda kune chero fluoroplastic
3. Kusagona makemikari ese
4.Hainamati zvakanyanya (kunyangwe chikwambo chingatsvedza paPTFE)
5. Ruvara runopenya
Dambudziko guru rePTFE nderekuti hainyungudike kana yapiswa saka inonetsa kugadzirisa. Matekiniki asina kujairika anodiwa kuti fluoropolymer iyi iumbwe, ibudiswe uye iunganidzwe.
Nekuda kwehunhu hwayo hwakasiyana, PTFE yakakodzera kushandiswa mukudzivirira magetsi uye kudzivirira zvikamu zvemagetsi.
Isu tiri nyanzvi yekugadzirapombi yeptfe， Kana muine mibvunzo, munogona kutibata!
Mabhenefiti eFEP
FEP, kana kuti Fluoroethylenepropylene, ndiyo PTFE inonyungudika. FEP ine hunhu hwakafanana nePTFE, asi ine tembiricha yakaderera yekushanda inosvika +200°C. Zvisinei, FEP inogona kugadziriswa zviri nyore uye inogona kusungirirwa nyore nyore uye kuumbwazve kuita ma profiles akaomarara.
Pamusoro pekuve nehunhu hwakasiyana hwe fluoroplastics, FEP ine mabhenefiti aya:
1. Kugona kupinza nekuumba patsva
2. Kupisa kwekushanda kwe -200°C kusvika +200°C - FEP inoramba ichichinjika pakupisa kwe cryogenic
3. Kusagona zvachose makemikari uye UV
4. Inoenderana neBio
5. Ruvara rwakajeka
Nekuda kwezvibatsiro izvi, FEP heat shrink ine tembiricha yakaderera uye inogona kudzikiswa zvakachengeteka pamusoro pezvinhu zvinonzwa tembiricha pasina kutya kukonzera kukuvara. Nekuda kweizvozvo, FEP yakakodzera kubatanidza zvikamu zvemagetsi zvinonzwa tembiricha uye zvishandiso.
Mabhenefiti ePFA
PFA, kana kuti Perfluoralkoxy, imhando yeFEP inodziya zvakanyanya. PFA ine hunhu hwakafanana neFEP asi inogona kushandiswa pakupisa kunosvika +260°C uku ichiramba ichinyungudika, nekuda kwekunyungudika kwakaderera pane PTFE.
Pamusoro pekunakidzwa nehunhu hwakasiyana hwe fluoropolymers, PFA inozvisiyanisa nekuva nemabhenefiti anotevera:
Tembiricha yekushanda inoenderera mberi ye +260°C - Iyi ndiyo tembiricha yepamusoro yekushanda kune chero fluoroplastic
1. Kubatanidza uye kugadzirazve chigadziko
2.Kudzivirira kwakanaka kwepermeability
3. Kuramba kwemakemikari kwakanaka, kunyangwe pakupisa kwakakwirira
4. Inoenderana neBio
5.Magiredhi ekuchena kwepamusoro anowanikwa
6. Ruvara rwakajeka
Dambudziko guru rePFA nderekuti rinodhura kupfuura PTFE neFEP.
PFA yakakodzera kushandiswa kunoda kuchena kwakanyanya, kuramba makemikari zvakanaka uye tembiricha yepamusoro yekushanda. Iyi fluoroplastic inoshandiswa zvakanyanya mumachubhu ekurapa, ma heat exchangers, mabhasikiti e semi-conductor, mapombi ne fittings, uye ma valve liners.
Pano paBesteflonIsu tiri nyanzvi mukupa mhinduro dze fluoropolymer itsva dzekushandisa kwako kwehunyanzvi. Tsvaga rumwe ruzivo nezveduZvigadzirwa zveFluoroplastic.
