Kupatsanura uye kuita kwePTFE bhodhi

Polytetrafluoroethylene board (inonziwo tetrafluoroethylene board, Teflon board, Teflon board) yakakamurwa kuita mhando mbiri: kuumba nekutendeuka. Yakagadzirwa nekutonhora. PTFE wekutendeuka bhodhi chakagadzirwa PTFE nebwe nokutsikirira, sintering uye peeling. Zvigadzirwa zvaro zvine akasiyana mashandisirwo uye akanakisa akazara zvivakwa: yakakwira uye yakadzika tembiricha kuramba (-192 ℃ -260 ℃), ngura kuramba (yakasimba asidi, yakasimba alkali, aqua regia, nezvimwewo), mamiriro ekunze, kupisa kukuru, kukwirira lubrication, isina kunamatira, Isina-chepfu uye mamwe maitiro akanaka kwazvo.

Polytetrafluoroethylene jira chinhu chemupolymer chinoumbwa ne polymerization ye tetrafluoroethylene. Chimiro chayo chakareruka se – [- CF2-CF2-] n-, iyo ine yakanakisa makemikari kugadzikana uye ngura kuramba (polytetrafluoroethylene Inotumidzwa sePTFE kana F4, ndiyo imwe yezvinhu zvinoramba ngura zvakanyanya pasi nhasi. “Plastic King ”izita rinowanzozivikanwa re polytetrafluoroethylene. Rudzi rwepurasitiki ine kurwisa kuri nani. Haibatwe neacids inozivikanwa, alkalis, Iyo ngura yemunyu uye oxidant haina zvayakanakira kunyangwe iine aqua regia, saka inonzi Plastic King. Kunze kwesimbi yakanyungudutswa uye mvura fluorine, inopokana nemamwe makemikari ese.Iyo inoshandiswa zvakanyanya muzvinhu zvakasiyana-siyana zvekuisa chisimbiso zvinoda kuramba asidi, alkalis uye organic solvents. yakanakisa tembiricha kuramba (inogona kushanda patembiricha ye + 250 ℃ kusvika -180 ℃ kwenguva yakareba) PTFE pachayo haina chepfu kuvanhu, asi iyo Perfluorooctanoate (PFOA), chimwe chezvinhu mbishi zvinoshandiswa mukugadzira maitiro , inofungidzirwa kuve ine carcinogenic mhedzisiro.

Kupisa: -20 ～ 250 ℃ (-4 ～ + 482 ° F), zvichibvumira kutonhora nekukurumidza uye kupisa, kana kumwe kushanda kwekutonhora uye kupisa.

Kumanikidza -0.1, 6.4Mpa (yakazara yakaipa kumanikidza kune 64kgf / cm2) (Fullvacuumto64kgf / cm2)

Kugadzirwa kwayo kwakagadzirisa matambudziko mazhinji munyika yangu yemakemikari, peturu, mishonga uye mimwe minda. Polytetrafluoroethylene zvisimbiso, gaskets, gaskets. Polytetrafluoroethylene zvisimbiso uye gaskets zvakagadzirwa nekumiswa polymerized polytetrafluoroethylene resin kuumbwa. Inofananidzwa nemamwe mapurasitiki, PTFE ine hunhu hwekushomeka kwemakemikari, uye yave ichishandiswa zvakanyanya sechinhu chekuisa chisimbiso uye yekuzadza zvinhu. Yayo yakakwana yekupisa yekuparadza zvigadzirwa painosvika mazana mashanu madigiri Celsius ndeye tetrafluoroethylene, hexafluoropropylene uye octafluorocyclobutane. Izvi zvigadzirwa zvinowora zvakanyanya zvinoparadza zvine fluorine magasi pane yakanyanya tembiricha.

Iko kushandiswa kwe PTFE pepa

Mhando dzakasiyana dzezvigadzirwa zvePTFE zvakatamba chinzvimbo chakakosha muhupfumi hwenyika senge makemikari indasitiri, michina, zvemagetsi, zvigadzirwa zvemagetsi, maindasitiri emauto, muchadenga, kuchengetedza kwezvakatipoteredza nemabhiriji. Tetrafluoroethylene board yakakodzera tembiricha -180 ℃ ~ + 250 ℃. Inonyanya kushandiswa semagetsi ekuputira zvinhu uye machira akasangana neinobvisa midhiya, inotsigira inotsvedza, zvisimbiso zenjanji uye zvigadzirwa zvekuzora. Yakapfuma cabinet yemidziyo inoishandisa mune yakajeka indasitiri. , Inoshandiswa zvakanyanya mumakemikari, mishonga, dhayi maindasitiri emidziyo, matangi ekuchengetedza, shongwe dzekuita, mapaipi mahombe anticorrosive lining zvinhu; kubhururuka, kwemauto uye mamwe anorema maindasitiri minda; michina, kuvaka, mabhureki emigwagwa, vatungamiriri; kudhinda uye kudhaya, indasitiri yakajeka, machira Anti-adhesive zvinhu zveiyo indasitiri, nezvimwe.
