Vakapararira PTFE Resin Nhanganyaya
Kuumbwa kwevakaparadzirwa PTFE Resin inenge 100% PTFE (polytetrafluoroethylene) resin. Vakapararira PTFE resin inogadzirwa uchishandisa nzira yekupararira uye yakakodzera paste extrusion, inozivikanwawo sepaste extrusion-grade PTFE resin. Iine zvinhu zvakasiyana-siyana zvakanakisa zve PTFE resin uye inogona kugadziriswa kuita hurefu hurefu hwemachubhu akatetepa-akakomberedzwa, tsvimbo, waya uye tambo yekuvharisa, gaskets, nezvimwe.
Production Process Sumo
Vakapararira PTFE resin poda inofanodzvanywa kuita pepa chimiro uchishandisa muchina wekukungurutsa, yobva yapinda muchina unopisa umo inodziiswa kwemaminetsi akati wandei pa200-370 ° C uye 100 kusvika 1000 mamiriro ekunze ekumanikidza kugadzira polytetrafluoroethylene sheet zvinhu izvo. unonzwisisa uye unoziva. Vakapararira PTFE resin poda inogona zvakare kuwedzerwa zvakananga kune mold uye inogadzirwa mune chero chimiro che PTFE chigadzirwa pasi pekumanikidzwa kwe200-370 ° C uye 100-1000 atmospheres of pressure. Kana 1% yeparafini wakisi ichiwedzerwa kune vakapararira PTFE resin, inogona kudzokororwa kakawanda kuti ibudise PTFE tepi yekuisa pombi. Iyo huru compressor piston mhete ine dhayamita ye1050 millimeters yakagadzirwa kubva mairi ine hupenyu hwesevhisi hurefu hunoenderera. Kuita kwayo kukuru ndeye "secondary processing performance" (isina kuzara polymerized, yakazara polymerized panguva yechipiri kugadzirisa), inogona kushandiswa kugadzira chero. PTFE zvikamu.
Zvimiro zveVakapararira PTFE Resin
Vakapararira PTFE iresin yehupfu ine kugadzikana kwekupisa, kusimba kwemakemikari inertness, epamusoro magetsi emagetsi, uye yakaderera coefficient yekukwesha. Aya maficha akatanhamara anoita kuti ive sarudzo yakanaka kune akasiyana maapplication.
Kushandisa Uye Hunhu
Zvigadzirwa izvi zvakagadzirirwa kusanganiswa ne organic zvinwiwa zvinoshandiswa sezvinowedzera, uye zvinogona kugadziriswa uchishandisa matekiniki akadai secalendering uye extrusion. Izvo zvakakodzerwa nekugadzira matanda madiki, machubhu akatetepa-akakomberedzwa, tambo dzekudzivirira tambo, uye mabhandi asina kuvharwa pachiyero chepakati kusvika pazasi compression ratios uye yepakati kusvika yakaderera extrusion rates.
Iyo SFN yakatevedzana inosanganisira SFN-1, SFN-3, SFN-A, uye SFN-5A. Iyo SFN yakatevedzana inopa yakanakisa makemikari kuramba, kusanganisira kuramba kune yakasimba acids, alkalis, uye oxidizing agents. Vanoratidza kupisa kwakatanhamara uye kutonhora kwekudzivirira, ine tembiricha yenguva refu yekushandisa kubva -190 ° C kusvika +250 ° C. Zvigadzirwa izvi zvine yakaderera friction coefficients, yakanakisa yekuzvizora zvivakwa, uye yepamusoro yemagetsi kuita. Izvo hazvikanganisirwe nekushisa kana kuwanda, uye hazvitevedzere, kutora unyoro, kupisa, kana kuona kuchembera kwakakosha pasi pemamiriro emuchadenga. Inoshandiswa zvakanyanya muindasitiri yemakemikari, michina, peturu, mushonga, zvemagetsi, optics uye mamwe minda.
Vakapararira PTFE resin inogona kukamurwa kuita mafomu maviri: hupfu uye yakadzika yekuparadzira mvura. Pakati pavo, poda yekuparadzira resin, mushure mekusanganiswa nehumwe huwandu hwekuwedzera (senge petroleum ether) uye fillers (yakadai sequartz upfu), yakakodzera kuumbwa kwekugadzira zvigadzirwa zvitete-madziro, sewaya netambo. Inoshandiswa zvakanyanya mune yazvino waya uye tambo indasitiri. Iyo poda yekuparadzira resin inogona zvakare kudzvanywa kuita muchimiro uye yobva yakungurutswa kuita firimu rakatetepa (rinozivikanwawo setepi) yekuvharisa kana kupfekedzwa kwewaya yakanaka dhayamita waya. Polytetrafluoroethylene concentrated dispersion fluid inonyanya kushandiswa kupfekedza pamusoro pezvinhu zvine porous (senge asbestos uye girazi faibha weaving) uye simbi inogadzirwa neupfu metallurgy nzira. The glass fiber weaving layer ye PTFE insulated electromagnetic wire uye high-temperature resistant waya yakaputirwa ne concentrated dispersion liquid ye polytetrafluoroethylene.
