Tasirin Ƙimar PTFE Emulsion pH akan Ƙarfinsa da Ayyukan Ciwon ciki

Jiangsu Aokai New Materials, PTFE high-zazzabi masana'anta masana'anta, ya bayyana yadda pH darajar polytetrafluoroethylene (PTFE) emulsion hidima a matsayin m siga tabbatar da aiki da kuma aikace-aikace yi. Samfuran na yau da kullun suna kula da tsayayyen ƙarancin alkaline pH na 8.0-10.5 . Canje-canje a cikin pH na iya haifar da amsawar sarkar daga micro zuwa matakan macro, yana shafar kwanciyar hankali na tsarin (misali, rayuwar shiryayye, ƙarfin hana coagulation) da aikin impregnation (misali, permeability, ingancin shafi na ƙarshe).

1. Tasiri akan Kwanciyar Hankali

PTFE emulsion shine tsarin da ba shi da kwanciyar hankali wanda kwanciyar hankali ya dogara ne akan rikitar da wutar lantarki tsakanin PTFE microparticles. pH yana daidaita wannan ma'auni kai tsaye.

Kayan aikin daidaitawa na Electrostatic (Mai yiwuwa Zeta)

A cikin yanayin rashin ƙarfi na alkaline, ƙananan ƙwayoyin PTFE sun zama mummunan caji ta hanyar adsorbing hydroxyl ions (OH⁻), tare da yuwuwar Zeta na kusan -50 mV zuwa -65 mV . Wannan karfi electrostatic repulsion ya isa ya shawo kan van der Waals sojojin da kuma ci gaba da barbashi tarwatsa.Idan pH saukad da isoelectric batu na PTFE (a kusa da pH 2.9-3.2), surface zargin da aka neutralized, da Zeta m fuskanci sifili, da emulsion da sauri destabilizes da kuma sha irreversible coagulation.

Tasirin Tabbatar da Muhalli na Alkaline

Kasuwancin PTFE emulsions ana kiyaye su da raunin alkaline galibi saboda dalilai masu zuwa:

· Hana ci gaban ƙananan ƙwayoyin cuta : Yanayin alkaline mai rauni yana hana ci gaban ƙwayoyin cuta, yana hana su daga cinyewar surfactants da lalata emulsion.

· Rushewar lalacewar acidic : Yanayin alkaline yana kawar da ragowar abubuwan acidic daga polymerization, guje wa lalata kayan aiki da lalata aiki.

Hatsarin Ƙara Acid

Lokacin daidaita pH tare da acid kamar acetic acid, dole ne a ƙara acid a hankali a cikin ƙananan adadi tare da motsawa mai laushi da pre-dilution. Ƙara sauri ko yawan acidity zai rushe ma'aunin cajin na tsarin kuma yana haifar da karyewar emulsion nan da nan.

2. Tasiri kan Ayyukan Ciwon ciki

Impregnation na bukatar emulsion yadda ya kamata shiga cikin substrate da samar da uniform shafi. pH yana rinjayar wannan tsari musamman ta hanyar canza danko, rashin ruwa, da cajin saman tsarin.

Permeability da Adhesion

pH yana rinjayar halayen rheological na emulsion. Madaidaicin pH yana inganta yadawa da shigar da capillary a saman ƙasa kuma yana guje wa lahani. Ƙananan ƙananan ko babba pH na iya rage mannewar shafi.

Maɓallin Maɓalli don Tsarin Haɗin kai

In composite material preparation, adjusting pH allows control of the Zeta potential of two or more types of particles, enabling uniform and efficient co-coagulation through electrostatic interaction. Misali, daidaita pH na carbon baki da PTFE emulsion cakuda zuwa 7-10  cimma cikakken coagulation ba tare da ƙarin coagulant.

A Aokai New Materials, pH iko a ko'ina emulsion shirye-shirye da kuma samar maida hankali ne akan dukan rayuwar PTFE emulsion daga ajiya zuwa karshe samfurin yi, yin shi da muhimmanci ga cikakken amfani da fice Properties na PTFE kayan.
