Taw qhia los ntawm a Teflon High-Temperature Fabric Chaw tsim tshuaj paus rau qhov sib txawv ntawm PTFE emulsions tsim los ntawm txawv Polymerization txheej txheem (Ncua tseg Polymerization thiab Dispersion Polymerization)
I. Kev Tshaj Tawm Ua Ntej ntawm Cov Tswv Yim
Hauv kev xyaum ua lag luam, ncua kev kawm polymerization tsis tuaj yeem tsim PTFE emulsion ncaj qha. Tiag tiag PTFE emulsion (dispersion) yog tsim los ntawm dispersion polymerization (uas yog qhov tseem ceeb emulsion polymerization). Jiangsu Teflon High-Temperature Fabric Chaw tsim tshuaj paus sau tseg tias muaj nyob rau hauv kev lag luam 'txheej txheem-txoj kev PTFE emulsion' yog tiag tiag aqueous suspension ua los ntawm mechanically dispersing suspension-polymerized resin micropowders. Qhov ob qhov sib txawv hauv paus, los ntawm qhov xwm txheej mus rau kev siv kawg.
II. Dispersion Polymerization: Thawj PTFE Emulsion
1. Particle Morphology thiab Stability
Cov hais yog zoo kawg nkaus kheej kheej, tsim los ntawm agglomeration ntawm thawj hais (0.05-0.5 μm) mus rau lwm yam hais nrog ib tug particle loj ntawm 0.1-0.3 μm thiab ib tug heev nqaim loj faib. Kev ruaj ntseg yog muab los ntawm perfluorinated surfactants (PFOA lwm txoj kev) ntxiv thaum lub sij hawm polymerization. Lub kaw lus colloidal tuaj yeem nyob ruaj khov yam tsis muaj stratification rau xyoo thiab nthuav tawm qhov ua haujlwm zoo rau cov tshuab shear.
Qhov hnyav molecular yog siab heev (txog li ob peb lab), nrog crystallinity tshaj 94% thiab muaj zog heev fibrillation muaj peev xwm. Tom qab txheej txheej, qhov kub thiab txias sintering ntawm kwv yees li 380 ° C yog qhov yuav tsum tau, thaum lub sij hawm cov khoom fuse mus rau hauv ib tug nruam, ntom, thiab tawv zaj duab xis nrog zoo heev anti-corrosion thiab tsis-stick zog.
3. Hom kev ua thiab kev siv
Kev ua tiav tsuas yog muab tshuaj txhuam extrusion, impregnation, lossis txheej tom qab sintering. Cov ntawv thov muaj xws li cov txheej txheem tsis-stick cookware, impregnation ntawm fiberglass architectural membranes, microporous ePTFE membranes ( breathable thiab waterproof), thiab high-end capacitor films.
III. Suspension Polymerization Micropowders: Aqueous Suspension (feem ntau mislabeled li emulsion)
1. Particle Morphology thiab Stability
Raws li tau sau tseg los ntawm Jiangsu Teflon High-Temperature Fabric Chaw tsim tshuaj paus: Cov khoom yog tsim los ntawm kev sib tsoo thiab crushing ncua kev kawm ntawv-polymerized pellets, uas ua rau tsis xwm yeem polyhedral duab nrog particle loj li ntawm 2 mus rau 20 μm thiab ib tug dav loj tis. Lub kaw lus yog thermodynamically tsis ruaj khov thiab nquag nquag mus rau sedimentation thiab stratification. Cov pa surfactants thiab thickeners xws li xanthan gum thiab cellulose ethers yuav tsum tau muab ntxiv rau retard sedimentation, thiab tag nrho stirring yog yuav tsum tau ua ntej siv.
Qhov hnyav molecular tuaj yeem hloov kho mus rau qhov qis qis (ntau txhiab mus rau ntau pua txhiab), nrog rau cov brittleness ntau dua thiab muaj peev xwm tsis muaj zog heev. Tom qab txheej, tsuas yog ambient los yog qis-kub qhuav yog yuav tsum tau los ua ib tug qhuav lubricating txheej; nws tsis tuaj yeem sintered rau hauv zaj duab xis.
3. Hom kev ua haujlwm thiab kev siv
Nws tuaj yeem raug muab tso ncaj qha rau hauv cov formulations los yog siv los ntawm txheej thiab cua qhuav. Cov ntawv thov suav nrog cov khoom siv roj nplua nyeem, roj hmab thiab yas pwm tso tawm cov neeg ua haujlwm, cov tshuaj tiv thaiv hnav thiab khaus khaus rau cov kua nplaum thiab cov coatings, thiab dej-repellent xov rau textiles.

Xaus los ntawm Jiangsu Teflon High-Temperature Fabric Chaw tsim tshuaj paus: Yog tias koj daim ntawv thov yuav tsum tau impregnation, txheej sintering, los yog zaj duab xis tsim, koj yuav tsum xaiv cov thawj PTFE emulsion ua los ntawm dispersion polymerization. Yog tias koj tsuas yog xav tau los txhim kho lubricity, tso tawm cov khoom, lossis kev puas tsuaj tsis muaj sintering, ces cov dej ncua kev kawm uas ua los ntawm kev ncua-polymerized micropowders yog qhov kev xaiv tsim nyog.
