Liphello tsa PTFE Emulsion pH Boleng ba Botsitso le Ts'ebetso ea Tsona.

Jiangsu Aokai New Materials, moetsi oa lesela la mocheso o phahameng oa PTFE, o hlalosa kamoo pH ea boleng ba emulsion ea polytetrafluoroethylene (PTFE) e sebetsang e le parameter ea bohlokoa e netefatsang ts'ebetso ea eona le ts'ebetso ea kopo. Lihlahisoa tse tloaelehileng hangata li boloka pH e tsitsitseng e fokolang ea alkaline ea 8.0-10.5 . Ho feto-fetoha ha pH ho ka tsosa karabelo ea ketane ho tloha maemong a manyane ho isa ho a macro, a ama botsitso ba sistimi (mohlala, bophelo ba sethala, matla a anti-coagulation) le ts'ebetso ea ho kenella (mohlala, ho kenella, boleng ba ho qetela ba ho roala).

1. Liphello ho Botsitso

PTFE emulsion ke tsamaiso e sa tsitsang ea thermodynamically eo botsitso ba eona bo itšetlehileng haholo ka ho furalla electrostatic pakeng tsa PTFE microparticles. pH e laola ka ho toba tekanyo ena ea bohlokoa.

Mokhoa oa ho tsitsisa oa Electrostatic (Zeta Potential)

Sebakeng se fokolang sa alkaline, li-microparticles tsa PTFE li qosoa hampe ke adsorbing hydroxyl ions (OH⁻), ka matla a Zeta a hoo e ka bang -50 mV ho -65 mV . Ts'ebetso ena e matla ea electrostatic repulsion e lekane ho hlōla matla a van der Waals le ho boloka likaroloana tse qhalakantsoeng.Haeba pH e theohela sebakeng sa isoelectric sa PTFE (ho pota-pota pH 2.9-3.2), litefello tsa holim'a metsi ha li fokotsehe, bokhoni ba Zeta bo atamela zero, 'me emulsion e potlakela ho senya le ho feta ho kopanya ho ke keng ha fetoloa.

Phello e tsitsitseng ea Tikoloho ea Alkaline

Li-emulsion tsa khoebo tsa PTFE li bolokiloe ka alkaline e fokolang haholo ka mabaka a latelang:

· Thibelo ea kholo ea likokoana-hloko : Tikoloho e fokolang ea alkaline e hatella kholo ea baktheria, e ba thibela ho ja li-surfactants le ho senya emulsion.

· Khatello ea ho senyeha ha asiti : Tikoloho ea alkaline e fokotsa lintho tse setseng tsa asiti ho tloha polymerization, ho qoba ho bola ha lisebelisoa le ho senyeha ha ts'ebetso.

Likotsi tsa Keketso ea Asiti

Ha o lokisa pH le acid e kang acetic acid, asiti e tlameha ho eketsoa butle-butle ka tekanyo e nyane ka ho sisinyeha ha bonolo le pele ho hlapolloa. Keketso e potlakileng kapa acidity e feteletseng e tla sitisa tekanyo ea tefiso ea sistimi hape e baka ho robeha ha emulsion hanghang.

2. Liphello ho Impregnation Performance

Impregnation e hloka hore emulsion e kene ka katleho substrate ebe e etsa seaparo se tšoanang. pH e susumetsa ts'ebetso ena haholo-holo ka ho fetola viscosity, wettability, le tefiso ea bokaholimo ba sistimi.

Permeability le Adhesion

pH e ama boitšoaro ba rheological ea emulsion. PH e nepahetseng e ntlafatsa ho kenella le ho kenella ha capillary holim'a substrate mme e qoba liphoso. pH e tlase haholo kapa e phahameng haholo e ka fokotsa ho khomarela ha lirala.

Parameter ea bohlokoa bakeng sa Ts'ebetso ea Co-Coagulation

Ha ho lokisoa lintho tse entsoeng ka motsoako, ho fetola pH ho lumella ho laola bokhoni ba Zeta ba mefuta e 'meli kapa ho feta ea likaroloana, ho nolofalletsa ho kopanya seaparo le se sebetsang hantle ka ho sebelisana ha electrostatic. Ka mohlala, ho fetola pH ea motsoako oa carbon black le PTFE emulsion ho 7-10  ho finyella coagulation e feletseng ntle le li-coagulants tse eketsehileng.

Ho Aokai New Materials, taolo ea pH ho pholletsa le ho lokisetsa emulsion le tlhahiso e akaretsa bophelo bohle ba PTFE emulsion ho tloha polokelong ho ea ho ts'ebetso ea sehlahisoa sa ho qetela, ho etsa hore ho be bohlokoa ho sebelisa ka botlalo thepa e hlahelletseng ea thepa ea PTFE.
