Chii chinonzi polychlotrotrluoroetherylene (PCFF)?

PCFA iri polymer ine mutsara wekudzosera kumashure kwekudzokorora zvikamu zvakatangwa neiyo yakanyanya-yakatangwa polymerization ye vinyl trifluoride.

PCFA iri crystalline polymer ine inonyungudika pfungwa ye127 ° C uye density of 2.13 g / cm3. PCTFER INERER kune akawanda anoshanda makemikari emakamuri tembiricha, nepo inogona kuve yakagadziriswa nemashoma mashoma uye akazvimba nemamwe masosi pamusoro pe21 ° C. PCTFE ine yakanaka gasi chipinganidzo kugona.

PCTFE ine yakanaka gasi yekukanganisa, uye iyo yemvura inokanganisa yefirimu zvigadzirwa zvemapurasitiki zvakaenzana neiyo yePRFLAROPOLOMY, pamigwagwa mikuru.

Mirayiridzo yekushandisa:

Polytrifluorolehlene ine simba rinotonhora zvakanyanya, simba rakanyanya uye kuomarara, rakaomesesa kukura kwemukati uye hapana maitiro ekutonhora anoyerera. Kufambidzana kwe1,2W / (MC) Simba re 70mpa. Izvo zvinodzivirira kune isorganic acids pakupisa kwakanyanya, saluble solid oxidizers pakudziya kwakadzika, uye zvakare kurwisa organic pamhepo tembiricha. Pakati, vharuvhu kushandisa kudzvinyirira pazasi 25mpa.

Izvo Zvikuru Zvivakwa zvePCFFE:

1

2. PKTFA yakaderera-kupokana kunonyanya kukosha, mumvura nitrogen

3. Yakakwira Fluorine Zvemukati inoita PCFER JATHER kune ese makemikari uye oxidizers. Inogona kuve isingabvumirwe muAcid, Alkali kana oxidizer kwenguva yakareba pasina kana shanduko chete, uye inogona kungo tembiricha yakanyanya nekunyungudika alkalive alkali, elemental fluorine uye chlorine trifluoride.

Chii chinoita kuti PCTFA yakasarudzika

Kuenzanisa PCTFE (PolychlotrotiRluoroetherylene) nePTFE (PolytetraFluorohylene - Iyo Workhorse yemhuri yeFluorolmymy) inotungamira kumhedziso inoshanda. Pakutanga kutarisa, iyo molecular mafomula yakafanana kunze kwekuti imwe fluorine atomu paPTFE MOLECULE inoshandurwa kuClorine atomu.

Nekudaro, izvi zvingaite senge shanduko diki; Kuwedzera kwechipfeko cheklorine kunotungamira kumisiyano mikuru mune yekupedzisira zvinhu zvezvinhu.

Ngatitarisei kutarisa kwemhedzisiro yeklorine maatomu pane zvivakwa zvinhu:

Kemical Resistance - PTFE izere yakanyatsonaka morekuru uye saka ingangoda kurwiswa nemakemikari, kunyange mune yakasimba acids. PKTFA yakaumbwa zvishoma, asi iyo polymer ine matatu emakiromita mana emaketomu, uye saka ane maitiro akanaka emakemikari, asi haasangane nemitemo yakakwirira yePTFE, kunyanya mune zvinosemesa uye halogenated sol.

Mechaniki Zvivakwa - PTFE kazhinji chigadzirwa chesarudzo kana yakakwira voltages, zvakanyanyisa makemikari kurwisa uye kwakanyanya kwekutora kwekuita zvinodiwa. Nekudaro, kana yakakwira dimensional kugadzikana pamusoro peyakawedzera tembiricha inodiwa, kana kana yakakwira mechanical simba rinodiwa, PTFE inogona kunge isina kukodzera iyi application. PCTFE ine kanenge kaviri kusimba kweiyo ptfe, ine yakaderera elongation uye yakajeka modulus iyo 2,5 times iyo yeTtfe.

Formal Properties - Kuwedzera kweChrorine maatomu kunoderedza iyo yekunyungudza nzvimbo yePKTFA kune 410 ° FACE PTFET PONT yePTFE ye621 ° F. Izvi zvinoda kutariswa mukushandisa kwako.

Mukupfupikisa, kugadzikana kwematare kwePCTFA kudonha pakati peiyo yePamberi Nyanzvi dzePolyty dzakadai sePSEEK, PPS uye PTFE, asi ichiri kugovera zvakanaka. Mukuwedzera, PCTFA ine yakaderera-yakaderera tsika uye yakaderera kupisa kweFluoropolysers.
