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 kuonetsetsa kuti ikukonzedwa ndikugwiritsa ntchito. Zogulitsa zodziwika bwino nthawi zambiri zimakhala ndi pH ya 8.0-10.5 yokhazikika . Kusinthasintha kwa pH kumatha kuyambitsa kusintha kwa chain kuchokera ku ma micro mpaka ma macro, kukhudza kukhazikika kwa dongosolo (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 imayendetsa 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 mphamvu 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 electrostatic interaction. Mwachitsanzo, kusintha pH ya kaboni wakuda ndi PTFE emulsion osakaniza kukhala 7-10  amakwaniritsa coagulation wathunthu popanda coagulants zina.

Pa Aokai New Equipment, pH kulamulira mu kukonzekera emulsion ndi kupanga chimakwirira moyo wonse wa PTFE emulsion kuchokera kusungirako kuti ntchito yomaliza mankhwala, kupanga izo zofunika mokwanira masuku pamutu kwambiri katundu PTFE zipangizo.

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

Kuti mudziwe zambiri, zochitika zamagwiritsidwe ntchito ndi mayankho makonda amtundu wathu wonse wamankhwala kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, malamba opanda msoko amakina omangira, nsalu imodzi ya PTFE, lamba wotentha kwambiri wosamva kutentha, malamba osamva kutentha kwambiri, magalasi apamwamba, kulumikizana ndi magalasi apamwamba kwambiri
