Ditlamorago tša Boleng bja pH bja PTFE Emulsion go Botsitso bja Yona le Tiragatšo ya go Impregnation

Jiangsu Aokai New Materials, e PTFE phahameng-mocheso lesela moetsi, hlalosa kamoo pH boleng ba polytetrafluoroethylene (PTFE) emulsion sebeletsa e le paramethara bohlokoa netefatsa tshebetso lona tshebetso le kopo tshebetso. Ditšweletšwa tše di tlwaelegilego ka tlwaelo di boloka tekanyo ya pH ye e tsepamego ya alkaline ye e fokolago ya 8.0–10.5 . Diphetogophetogo tša pH di ka hlohleletša karabelo ya ketane go tšwa go maemo a micro go ya go a macro, go ama go tsepama ga tshepedišo (mohlala, bophelo bja šelefo, bokgoni bja go lwantšha go kgotlelela) le tshepedišo ya go impregnation (mohlala, go tsenelela, boleng bja mafelelo bja go tlotša).

1. Ditlamorago go Botsitso

PTFE emulsion ke thermodynamically sa tsitsitseng tsamaiso eo botsitso haholo-holo itšetlehile ka electrostatic repulsion pakeng tsa PTFE microparticles. pH e laola ka go lebanya tekatekano ye ya senotlelo.

Mokgwa wa go Tsepamiša Mohlagase (Zeta Potential) .

Tikologong ya alkaline ye e fokolago, dikarolwana tše nnyane tša PTFE di ba le tefo ye mpe ka go monya di-ion tša hydroxyl (OH−), ka bokgoni bja Zeta bja mo e ka bago -50 mV go ya go -65 mV . Ena matla electrostatic repulsion e lekane ho hlōla van der Waals matla le ho boloka dikarolwana dispersed.Ge pH theoha ho isoelectric ntlha ya PTFE (ho pota pH 2.9-3.2), ditefiso holim'a bokagodimo ba neutralized, Zeta bokgoni batamela lefela, 'me emulsion ka potlako destabilizes le undergoes irreversible coagulation.

Phello ya go Tsepamiša ya Tikologo ya Alkaline

Di-emulsion tša PTFE tša kgwebo di bolokwa di fokola alkaline kudu ka mabaka a a latelago:

· Thibelo ya kgolo ya diphedinyana tše nnyane : Tikologo ya alkaline ye e fokolago e gatelela kgolo ya dipaketheria, e di thibela go ja didirišwa tša go šoma godimo ga mmu le go šitiša emulsion.

· Kgatelelo ya go senyega ga esiti : Tikologo ya alkaline e neutralizes dilo tša mašaledi tša esiti go tšwa go polymerization, go efoga go tšhungwa ga didirišwa le go senyega ga tshepedišo.

Dikotsi tša Tlaleletšo ya Esiti

Ge o beakanya pH ka diesiti tša go swana le esiti ya asetiki, esiti e swanetše go okeletšwa ka go nanya ka palo ye nnyane ka go hlohleletša ka boleta le go hlatswa pele. Go tlaleletša ka lebelo goba esiti ye e feteletšego e tla šitiša tekatekano ya tefo ya tshepedišo gomme gape ya hlola go thubega ga emulsion ka pela.

2. Ditlamorago go Tiragatšo ya go Impregnation

Impregnation e nyaka gore emulsion e tsenelele ka mo go atlegilego ka gare ga substrate le go bopa go tlotša ga go swana. pH e tutuetša tshepedišo ye kudu ka go fetoša viscosity, wettability, le tefo ya bokagodimo bja tshepedišo.

Go tsenelela le go kgomarela

pH e ama boitshwaro bja rheological bja emulsion. pH ya maleba e optimizes go phatlalala le go tsenelela ga capillary godimo ga substrate gomme e efoga diphošo. pH ya fase kudu goba ya godimo e ka fokotša go kgomarela ga go tlotša.

Paramethara ya bohlokwa bakeng sa Tshepetšo ya Co-Coagulation

Ka go lokišetša dilo tše di kopanego, go beakanya pH go dumelela taolo ya bokgoni bja Zeta bja mehuta ye mebedi goba go feta ya dikarolwana, go kgontšha co-coagulation ye e swanago le ye e šomago gabotse ka tirišano ya electrostatic. Ka mohlala, go beakanya pH ya motswako wa emulsion ya khapone ye ntsho le ya PTFE go fihla go 7-10  go fihlelela go kgotlelela ka botlalo ntle le di-coagulants tša tlaleletšo.

Go Aokai New Materials, taolo ya pH go ralala le go lokišetša le tšweletšo ya emulsion e akaretša modikologo ka moka wa bophelo wa emulsion ya PTFE go tloga polokelong go fihla go tshepedišo ya mafelelo ya setšweletšwa, go dira gore go be bohlokwa go šomiša ka botlalo dithoto tše di tšwetšego pele tša didirišwa tša PTFE.

Tshedimošo ye e lego ka mo godimo e filwe ke Jiangsu Aokai New Materials Technology Co., Ltd.
