PTFE Hmoov Plasma Hydrophilic Kev Kho Mob
PTFE Hmoov Plasma Hydrophilic Kev Kho Mob
PTFE hmoov yog dav siv los ua ib qho ntxiv hauv ntau cov kuab tshuaj thiab cov hmoov coatings, xws li yas coatings, ntoo xim, coil coatings, UV curing coatings, thiab xim, los txhim kho lawv cov pwm tso tawm kev ua tau zoo, nto khawb kuj, lubricity, tshuaj tiv thaiv, huab cua tsis kam, thiab waterproofing. PTFE micro-powder tuaj yeem siv los ua cov khoom siv roj nplua nyeem tsis yog kua roj. Lawv kuj tuaj yeem siv los txhim kho cov dej ntws ntawm tus cwj mem thiab ua tus neeg sawv cev tiv thaiv, nrog rau qhov sib ntxiv ntawm 1-3wt%. Lawv kuj tuaj yeem siv rau hauv cov txheej tsis lo rau cookware, nrog rau qhov sib ntxiv ntawm tsis pub ntau tshaj 5wt%. Organic solvent dispersion tuaj yeem siv los ua tus neeg sawv cev tso tawm. Lawv kuj tuaj yeem siv los ua cov tshuaj tiv thaiv zoo hauv ntau yam yas, xws li ABS, polycarbonate (PC), polyurethane (PU), thiab polystyrene (PS).
PTFE yog ib qho crystalline polymer ua los ntawm tetrafluoroethylene monomers, nrog cov hluav taws xob zoo heev, tsis tshua muaj kev sib txhuam thiab kev sib txhuam coefficient, tsis-flammable, tsis kam mus rau atmospheric aging, siab thiab qis-kub adaptability, thiab siab mechanical zog.
Txawm li cas los xij, vim nws cov qauv zoo sib xws thiab tsis yog-polar, tsis muaj cov pab pawg ua haujlwm, thiab siab crystallinity, PTFE yog ib yam khoom uas tsis yog-polar uas muaj zog hydrophobicity, tshuaj inertness, tsis tshua muaj zog nto, thiab tsis zoo wettability thiab adhesion rau lwm yam ntaub ntawv, uas zoo heev txwv nws daim ntawv thov. Yog li ntawd, kom nthuav daim ntawv thov ntawm PTFE, nws nto yuav tsum tau kho kom nws nto zog thiab txhim kho nws hydrophilicity.
Kev kho mob ntshav plasma yog ib qho ntawm cov thev naus laus zis tsim kho sai rau PTFE kev hloov kho saum npoo av nyob rau xyoo tas los no. Lub hauv paus ntsiab lus ntawm kev hloov ntshav plasma yog siv ion bombardment los yog txhaj tshuaj rau saum npoo ntawm cov polymer los tsim cov ntawv cog lus tawg lossis qhia cov pab pawg ua haujlwm, yog li ua kom lub ntsej muag txhawm rau txhim kho cov khoom ntawm qhov adhesion. Cov pa roj carbon monoxide feem ntau siv xws li oxygen, hydrogen, nitrogen, carbon tetrafluoride, thiab argon. Lub foob pob ntawm inert gas plasma tuaj yeem hloov cov qauv ntawm cov copolymer.
Plasma muaj cov khoom nquag xws li electrons, ions, thiab dawb radicals. Kev hloov kho saum npoo ntawm plasma suav nrog kev hloov kho lub cev thiab tshuaj lom neeg. Kev hloov kho lub cev yog kev foob pob hluav taws xob ntawm cov hluav taws xob thiab ions ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, uas rhuav tshem cov tshuaj lom neeg ntawm cov saw hlau polymer, ua rau muaj kev cuam tshuam degradation, thiab tsim cov khoom degradation uas tso rau ntawm cov khoom polymer. Kev hloov kho tshuaj muaj xws li qhia cov pab pawg ua haujlwm los ntawm cov dawb radicals reacting nrog polymer nto, hloov cov tshuaj muaj pes tsawg leeg ntawm qhov chaw. Kev hloov kho lub cev thiab tshuaj lom neeg yuav ua rau muaj kev hloov pauv ntawm cov khoom nto. Thaum kho cov ntshav plasma, kev taw qhia ntawm cov pab pawg ua haujlwm thiab cov tshuaj tiv thaiv degradation tsis tuaj yeem sib cais tab sis tshwm sim ib txhij, thiab kev cuam tshuam degradation yog qhov tsis muaj tseeb. Tus yuam sij rau kev hloov kho saum npoo zoo yog kom txo qis cov kev cuam tshuam degradation thiab ua kom lub luag haujlwm loj tshaj plaws ntawm kev ua haujlwm pab pawg qhia.
cov PTFE hmoov hloov kho siv cov hmoov plasma ntxuav tshuab. Plasma ua rau cov hmoov ua kom lub hom phiaj hloov nws lub cev thiab tshuaj lom neeg lub zog, thaum tswj cov khoom qub ntawm cov hmoov, muab nws cov khoom tshiab, hloov nws cov khoom saum npoo los ntawm hydrophobic mus rau hydrophilic los yog vice versa, yog li txhim kho lub wettability ntawm hmoov thiab txhim khu lub adhesion ntawm hmoov hais nyob rau hauv nruab nrab.
