PTFE Emulsion pH Value nɔ minnu bɛ a sabatili n’a impregnation baarakɛcogo la

Jiangsu Aokai New Materials, n’o ye PTFE finiw dilannikɛla ye min funteni ka bon, o b’a ɲɛfɔ cogo min na politetrafluoroethylene (PTFE) emulsion pH hakɛ bɛ kɛ fɛn nafamaba ye min b’a baarakɛcogo n’a kɛcogo sabati. a ka c’a la , fɛn minnu bɛ kɛ ka caya , olu bɛ pH sabatilen mara ni alkali barikama ye , o ye 8,0–10,5 ye . pH jiginni bɛ se ka cakɛda kɛ ka bɔ mikro la ka taa makɔrɔ hakɛ la, o bɛ nɔ bila sistɛmu sabatili la (misali la, a marali waati, a ka se ka joli segin a la) ani a falencogo baarakɛcogo (misali la, a bɛ se ka don a kɔnɔ, a laban cogoya).

1. A nɔ minnu bɛ sɔrɔ sabatili la

PTFE emulsion ye sigida ye min tɛ sabati funteni siratigɛ la, min sabatili bɛ tali kɛ kosɛbɛ kuran bɔli la PTFE mikroparticules ni ɲɔgɔn cɛ. pH bɛ o balansi kunbaba in ɲɛnabɔ k’a ɲɛsin a yɛrɛ ma.

Kuran sabatili fɛɛrɛ (Zeta Potential) .

Alkali barikama sigida la, PTFE mikroparticules bɛ kɛ charge négative ye ni hydroxyl ions (OH−) adsorbition ye, ni Zeta potentiel ye -50 mV fo -65 mV ɲɔgɔn na . O kuran-sɛnɛ barikama in bɛ se ka se sɔrɔ van der Waals fanga kan ani ka fɛnɲɛnamafagalanw to u ka jɛnsɛn.Ni pH jigira ka se PTFE ka isoelektriki yɔrɔ ma (pH 2,9–3,2 lamini), surface charges bɛ neutraliser, Zeta potentiel bɛ gɛrɛ zeru la, ani emulsion bɛ basigi teliya la ani ka coagulation kɛ min tɛ se ka segin kɔ.

Alkaline sigida laminiko sabatili nɔ

Jagokɛla ka PTFE emulsiɔnw bɛ mara alkali barikama ye kɛrɛnkɛrɛnnenya la nin kun ninnu de kama:

· Mikorobiyɔmuw ka bonya balili : Lamini min barika ka dɔgɔn, o bɛ banakisɛw falenni bali, ka u bali ka surɔfɛnw dun ani ka emulsiɔn sabati.

· Asidi tiɲɛni dabila : Alkali sigida bɛ asidi tolenw kɛ fɛn ye min tɛ se ka kɛ polimɛrizi ye, ka minɛnw sɔgɔli ni baarakɛcogo tiɲɛni bali.

Farati minnu bɛ asidi farali la

Ni aw bɛ pH ladilan ni asidiw ye i n’a fɔ asidi asetiki, asidi ka kan ka fara a kan dɔɔni dɔɔni ni a wulilen don dɔɔni dɔɔni ani ka kɔn ka a wuli. A farali teliya la walima asidi kojugu bɛna kɛ sababu ye ka sistɛmu ka charge balance tiɲɛ ani fana ka kɛ sababu ye ka emulsion kari teliya la.

2. A nɔ minnu bɛ sɔrɔ kɔnɔmaya kɛcogo la

Impregnation bɛ a ɲini emulsion fɛ a ka don substrat kɔnɔ ka ɲɛ ani ka kɛ finimugu kelen ye. pH bɛ nɔ bila o wale in na kosɛbɛ ni a bɛ sigida in ka sɔgɔsɔgɔninjɛ, a jisigicogo ani a sanfɛla charge (yɔrɔ) caman caman cili ye.

Perméabilité ani Adhesion (Dɔgɔyali ni Nɔrɔli).

pH bɛ nɔ bila emulsiɔn ka rheological kɛcogo la. pH bɛnnen bɛ jɛnsɛnni ni joli-sira-funu doncogo ɲɛ ka ɲɛ substrat sanfɛ ani ka a yɛrɛ tanga fiɲɛw ma. Ni pH dɔgɔyara kojugu walima ni a ka bon kojugu, o bɛ se ka dɔ bɔ finimugu nɔrɔli la.

Paramɛtiri jɔnjɔn min bɛ kɛ ka ɲɛsin Co-coagulation Process ma

Fɛnɲɛnɛma labɛnni na, pH ladilanni bɛ sira di Zeta seko kɔlɔsili ma fɛnɲɛnamafagalan suguya fila walima caman na, o bɛ kɛ sababu ye ka coagulation kelen ni nafama kɛ ni kuran jɛɲɔgɔnya ye. Misali la, ni aw ye karɔbɔni nɛrɛma ni PTFE emulsiyɔn ɲagaminen pH ladilan ka se 7–10 ma  , o bɛ kɛ sababu ye ka joli kuru dafalen sɔrɔ ni joli segin fura wɛrɛw tɛ.

Aokai New Materials la, pH kɔlɔsili emulsiyɔn labɛnni n’a dilanni bɛɛ kɔnɔ, o bɛ PTFE emulsiyɔn ɲɛnamaya bɛɛ lajɛlen datugu k’a ta a marali la ka se a dilanni laban kɛcogo ma, o b’a to a nafa ka bon ka PTFE fɛnw ka jogo ɲumanw nafa bɛrɛbɛrɛ.
