Nhanganyaya na Teflon Yepamusoro-Tembiricha Mugadziri Wemucheka kune Musiyano Pakati pePTFE Emulsions Yakagadzirwa Neakasiyana Polymerization Matanho (Kumiswa Polymerization uye Dispersion Polymerization)
I. Kujekeswa Kwekutanga kweMafungiro
Mumaindasitiri maitiro, kumisa polymerization hakugone kuburitsa zvakananga PTFE emulsion. Genuine PTFE emulsion (kupararira) inogadzirwa chete nekupararira kwepolymerization (iyo inonyanya emulsion polymerization). Jiangsu Teflon High-Temperature Fabric Manufacturer inocherekedza kuti inotengeswa 'suspension-method PTFE emulsion' ndeye kumiswa kwemvura kunogadzirwa nemuchina kuparadzira suspension-polymerized resin micropowders. Izvo zviviri zvinosiyana zvakanyanya, kubva kune chidimbu hunhu kusvika kumagumo-kushandisa maapplication.
II. Dispersion Polymerization: Yekutanga PTFE Emulsion
1. Particle Morphology uye Kugadzikana
Zvimedu zvakatenderedzwa zvakakwana, zvakaumbwa nekubatanidzwa kwezvikamu zveprimary (0.05-0.5 μm) muzvikamu zvechipiri zvine saizi ye0.1-0.3 μm uye kupararira kwakatetepa zvakanyanya. Kugadzikana kunopihwa neperfluorinated surfactants (PFOA dzimwe nzira) yakawedzerwa panguva yepolymerization. Iyo colloidal system inogona kuramba yakagadzikana isina stratification kwemakore uye inoratidza kuramba kwakanaka kune mechanic shear.
Huremu hwemamorekuru hwakanyanya kukwirira (kusvika mamirioni akati wandei), ine crystallinity inopfuura 94% uye yakasimba kwazvo fibrillation kugona. Mushure mekuputira, kutonhora kwepamusoro-soro kunenge ku380 ° C kunodiwa, panguva iyo zvimedu zvinosanganiswa mufirimu inoenderera, yakaoma, uye yakaoma ine anti-corrosion yakanakisa uye isina-tsvimbo.
3. Typical Processing uye Applications
Kugadzirisa kunogumira kunama extrusion, impregnation, kana coating inoteverwa ne sintering. Mashandisirwo akajairika anosanganisira asiri-stick cookware coatings, impregnation yefiberglass architectural membranes, microporous ePTFE membranes (inofema uye isingapinde mvura), uye yakakwirira-magumo capacitor mafirimu.
III. Suspension Polymerization Micropowders: Aqueous Suspension (Kazhinji Inonzi Mislabed seEmulsion)
1. Particle Morphology uye Kugadzikana
Sezvakataurwa naJiangsu Teflon High-Temperature Fabric Manufacturer: Zvimedu zvinogadzirwa nekukuya uye kupwanya kumiswa-polymerized pellets, zvichiita kuti zvive zvisina kujairika polyhedral maumbirwo ane particle size kubva ku2 kusvika ku20 μm uye kugoverwa kwehukuru hwakafara. Iyo sisitimu haina kugadzikana ine thermodynamically uye yakanyanya kukurumidza kuita sedimentation uye stratification. Zvakajairwa ma surfactants uye makobvu senge xanthan chingamu uye cellulose ethers zvinofanirwa kuwedzerwa kudzoreredza sedimentation, uye kunyatsokuchidzira kunodiwa usati washandiswa.
Huremu hwemamorekuru hunogona kugadziridzwa kune huremu hwakaderera (makumi ezviuru kusvika kumazana ezviuru), nehukuru brittleness uye kushaya simba kwefibrillation. Mushure mekuputira, chete ambient kana kuderera-kupisa kuomeswa kunodiwa kuumba yakaoma lubricating layer; haigoni kunyorwa mufirimu.
3. Typical Processing uye Applications
Inogona kuiswa zvakananga mukugadzirwa kana kushandiswa nekuputira uye kuomeswa nemhepo. Zvishandiso zvinosanganisira maindasitiri ekuwedzera mafuta ekuzora, rabha uye epurasitiki mold kuburitsa maajenti, anti-kupfeka uye anotsvedza eingi uye machira, uye inodzivirira mvura kupera kwemachira.
IV. Quick Reference: Core Misiyano
Particle Origin
Dispersion polymerization zvidimbu: akaumbwa mu-situ kuita spherical zvimiro kuburikidza nekuparadzira polymerization;
Suspension method particles: ivhu kubva muhombe resin kuita zvisina kujairika granules.
Particle Size
Raw dispersion emulsion: 0.1–0.3 μm ine nhete particle size distribution;
Suspension fluid: 2–20 μm ine yakafara particle saizi kugovera.
Stabilizer
Dispersion polymerization: perfluorinated surfactants;
Suspension liquid: yakajairika surfactants plus thickeners.
Film-kuumba Property
Dispersion polymerization: mafomu anoenderera, akaoma firimu mushure mekupisa-kupisa sintering;
Suspension liquid: isiri-firimu-inogadzira, inongoburitsa yakaoma lubricating layer.
Main Applications
Dispersion polymerization: mabhanhire asina-tsvimbo, anti-corrosion linings, mafirimu anoshanda;
Suspension liquid: anti-friction agents, maajenti ekusunungura, kupfeka-resistant additives for inki.
Mhedziso kubva kuJiangsu Teflon Yepamusoro-Tembiricha Mugadziri Wemucheka: Kana chikumbiro chako chichida kupfekedzwa, coating sintering, kana kugadzira firimu, iwe unofanirwa kusarudza yekutanga PTFE emulsion inogadzirwa nekuparadzira polymerization. Kana iwe uchingoda kuvandudza lubricity, kuburitsa zvivakwa, kana abrasion kuramba pasina sinter, saka iyo aqueous kuturika yakagadzirwa kubva kususpension-polymerized micropowders isarudzo yakakodzera.
Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Material Technology Co., Ltd.
Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandisa, uye zvigadziriso zvekugadzirisa zvemhando yedu yakazara yezvigadzirwa-kusanganisira Teflon yakakwirira-tembiricha machira, Teflon yakakwirira-tembiricha matepi, Teflon yakakwirira-tembiricha mesh mabhandi, musono-chisimbiso muchina mabhandi asina musono, single-sided, high-temperature PTFE machira. high-temperature fiberglass machira-ndapota inzwa wakasununguka kutibata nesu kuburikidza nezvinotevera:
