Zotsatira za PTFE Emulsion pH Phindu pa Kukhazikika Kwake ndi Kukonzekera Kwake

Jiangsu Aokai New Materials, wopanga nsalu zotentha kwambiri za PTFE, akufotokoza momwe pH mtengo wa polytetrafluoroethylene (PTFE) emulsion imagwirira ntchito ngati gawo lofunikira kuwonetsetsa kuti ikugwira ntchito ndikugwiritsa ntchito. Zogulitsa zodziwika bwino nthawi zambiri zimakhala ndi pH ya 8.0-10.5 yokhazikika . Kusinthasintha kwa pH kumatha kuyambitsa mayendedwe ang'onoang'ono mpaka ma macro, kukhudza kukhazikika kwadongosolo (mwachitsanzo, moyo wa alumali, anti-coagulation mphamvu) ndi magwiridwe antchito (mwachitsanzo, permeability, mtundu womaliza wokutira).

1. Zotsatira pa Kukhazikika

PTFE emulsion ndi thermodynamically wosakhazikika dongosolo amene kukhazikika makamaka amadalira electrostatic repulsion pakati PTFE microparticles. pH imayang'anira mwachindunji izi.

Electrostatic Stabilization Mechanism (Zeta Potential)

M'malo a alkaline ofooka, ma microparticles a PTFE amakhala olakwika ndi adsorbing hydroxyl ions (OH⁻), ndi Zeta zomwe zingatheke pafupifupi -50 mV mpaka -65 mV . Kuthamangitsidwa kwamphamvu kwa electrostatic uku ndikokwanira kugonjetsa mphamvu za van der Waals ndikusunga tinthu tating'onoting'ono.Ngati pH imatsikira kumalo a isoelectric a PTFE (kuzungulira pH 2.9-3.2), zolipiritsa zapamtunda zimakhala zopanda mphamvu, Zeta zomwe zingatheke zimayandikira zero, ndipo emulsion imasokoneza mofulumira ndikugwirizanitsa kosasinthika.

Kukhazikika kwa Chilengedwe cha Alkaline

Ma emulsions amalonda a PTFE amasungidwa amchere ofooka makamaka pazifukwa izi:

Kuletsa kukula kwa tizilombo tating'onoting'ono : Malo ofooka a alkaline amalepheretsa kukula kwa bakiteriya, kuwalepheretsa kudya zowonjezera komanso kusokoneza emulsion.

Kuletsa kuwonongeka kwa acidic : Malo amchere amachepetsa zinthu zotsalira za acidic kuchokera ku polymerization, kupewa dzimbiri za zida ndi kuwonongeka kwa magwiridwe antchito.

Zowopsa Zowonjezera Acid

Posintha pH ndi zidulo monga acetic acid, asidiyo ayenera kuwonjezeredwa pang'onopang'ono pang'onopang'ono ndikuyambitsa pang'onopang'ono komanso kuchepetsedwa. Kuwonjezeka kwachangu kapena acidity yochulukirapo idzasokoneza kuchuluka kwa kachitidwe kachitidwe ndikupangitsanso kusweka kwa emulsion.

2. Zotsatira pa Impregnation Magwiridwe

Impregnation imafuna emulsion kuti alowe bwino mu gawo lapansi ndikupanga zokutira yunifolomu. pH imakhudza njirayi makamaka posintha kukhuthala, kunyowa, ndi kuchuluka kwapamwamba kwa dongosolo.

Permeability ndi Adhesion

pH imakhudza khalidwe la rheological la emulsion. PH yoyenera imakulitsa kufalikira ndi kulowa kwa capillary pamtunda wapansi ndikupewa zolakwika. Kutsika kwambiri kapena kutsika kwa pH kumachepetsa kumamatira kwa zokutira.

Zofunika Kwambiri pa Co-Coagulation Process

Pokonzekera zinthu zophatikizika, kusintha pH kumathandizira kuwongolera mphamvu ya Zeta ya mitundu iwiri kapena kuposerapo ya tinthu tating'onoting'ono, ndikupangitsa kuti yunifolomu igwirizane komanso kugwirizanitsa bwino pogwiritsa ntchito ma electrostatic interaction. Mwachitsanzo, kusintha pH ya kaboni wakuda ndi PTFE emulsion osakaniza kukhala 7-10  amakwaniritsa coagulation wathunthu popanda coagulants zina.

Pa Aokai New Materials, pH kulamulira mu kukonzekera emulsion ndi kupanga chimakwirira lonse lifecycle wa PTFE emulsion kuchokera yosungirako kuti chomaliza mankhwala ntchito, kupanga izo zofunika mokwanira masuku pamutu kwambiri katundu PTFE zipangizo.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve zambiri, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, malamba opanda waya wamakina omangira, nsalu za PTFE zambali imodzi, lamba wosamva kutentha kwambiri, malamba osamva kutentha kwambiri, magalasi osamva kutentha kwambiri:
