Cov teebmeem ntawm PTFE Emulsion pH Tus nqi ntawm nws txoj kev ruaj khov thiab kev ua haujlwm impregnation

Jiangsu Aokai Cov Khoom Tshiab, PTFE cov chaw tsim khoom kub kub, piav qhia tias pH tus nqi ntawm polytetrafluoroethylene (PTFE) emulsion ua haujlwm li cas rau qhov tseem ceeb ntawm kev ua haujlwm thiab kev ua haujlwm. Cov khoom lag luam tseem ceeb feem ntau tuav ruaj khov tsis muaj zog alkaline pH ntau ntawm 8.0-10.5 . Kev hloov pauv hauv pH tuaj yeem ua rau muaj kev sib txuas ntawm cov tshuaj tiv thaiv los ntawm micro mus rau qib macro, cuam tshuam rau qhov system stability (xws li, txee lub neej, anti-coagulation muaj peev xwm) thiab impregnation kev ua tau zoo (xws li, permeability, zaum kawg txheej zoo).

1. Qhov cuam tshuam rau kev ruaj ntseg

PTFE emulsion yog ib qho thermodynamically tsis ruaj khov uas nws ruaj khov tsuas yog nyob ntawm electrostatic repulsion ntawm PTFE microparticles. pH ncaj qha tswj qhov sib npaug tseem ceeb no.

Electrostatic Stabilization Mechanism (Zeta Muaj Peev Xwm)

Nyob rau hauv ib puag ncig tsis muaj zog alkaline, PTFE microparticles ua tsis zoo los ntawm adsorbing hydroxyl ions (OH⁻), nrog Zeta peev xwm ntawm -50 mV rau -65 mV . Qhov no muaj zog electrostatic repulsion yog txaus los kov yeej van der Waals rog thiab ua kom cov khoom tawg.Yog pH poob rau lub isoelectric point ntawm PTFE (nyob ib ncig ntawm pH 2.9-3.2), deg tsub nqi neutralized, lub Zeta tej zaum zero, thiab cov emulsion sai destabilizes thiab undergoes irregularities.

Stabilizing nyhuv ntawm Alkaline ib puag ncig

Kev lag luam PTFE emulsions tau khaws cia tsis muaj zog alkaline feem ntau yog vim li cas hauv qab no:

· Inhibition ntawm microbial kev loj hlob : Ib puag ncig tsis muaj zog alkaline inhibits cov kab mob loj hlob, tiv thaiv lawv los ntawm kev noj cov surfactants thiab destabilizing cov emulsion.

· Tiv thaiv acidic degradation : Lub alkaline ib puag ncig neutralizes residual acidic tshuaj los ntawm polymerization, zam cov khoom siv corrosion thiab degradation.

Kev pheej hmoo ntawm Acid Ntxiv

Thaum kho pH nrog cov kua qaub xws li acetic acid, cov kua qaub yuav tsum tau maj mam ntxiv me me nrog maj mam nplawm thiab ua ntej dilution. Kev sib ntxiv nrawm los yog acidity ntau dhau yuav cuam tshuam cov nqi sib npaug ntawm lub cev thiab tseem ua rau emulsion tawg tam sim ntawd.

2. Cov teebmeem ntawm Impregnation Performance

Impregnation xav tau cov emulsion kom zoo nkag mus rau hauv lub substrate thiab tsim ib txheej txheej. pH cuam tshuam cov txheej txheem no feem ntau los ntawm kev hloov cov viscosity, wettability, thiab saum npoo ntawm lub cev.

Permeability thiab Adhesion

pH cuam tshuam rau tus cwj pwm rheological ntawm emulsion. Ib qho pH tsim nyog optimizes kev sib kis thiab capillary nkag mus rau ntawm lub substrate nto thiab zam qhov tsis xws luag. Tsis tshua muaj pH los yog siab heev yuav txo tau txheej adhesion.

Qhov tseem ceeb Parameter rau Co-Coagulation txheej txheem

Hauv kev npaj cov khoom sib xyaw, kev kho pH tso cai rau kev tswj hwm ntawm Zeta muaj peev xwm ntawm ob lossis ntau hom kab lus, ua kom muaj kev sib txuam thiab ua tau zoo co-coagulation los ntawm kev sib cuam tshuam electrostatic. Piv txwv li, kho cov pH ntawm cov pa roj carbon dub thiab PTFE emulsion sib tov rau 7-10  ua tiav coagulation tsis muaj coagulants ntxiv.

Ntawm Aokai Cov Khoom Tshiab, pH tswj thoob plaws hauv emulsion npaj thiab ntau lawm npog tag nrho lub neej voj voog ntawm PTFE emulsion los ntawm kev cia mus rau qhov kawg khoom ua tau zoo, ua rau nws tseem ceeb heev rau tag nrho cov khoom zoo ntawm PTFE cov ntaub ntawv.

Cov ntaub ntawv saum toj no yog muab los ntawm Jiangsu Aokai New Materials Technology Co., Ltd.

Rau cov ncauj lus kom ntxaws, daim ntawv thov scenarios thiab customized kev daws teeb meem ntawm peb cov khoom tag nrho xws li PTFE high-temperature daim ntaub, PTFE high-temperature daim kab xev, PTFE high-temperature mesh siv, seamless siv rau kev sib txuas tshuab, ib leeg-sab PTFE ntaub, high-temperature resistant conveyor siv thiab high-temperature, thov hu rau fiberglass.
