Mhedzisiro yePTFE Emulsion pH Kukosha paKugadzikana Kwayo uye Impregnation Performance

Jiangsu Aokai New Materials, a PTFE anogadzira machira epamusoro-tembiricha, anotsanangura kuti pH kukosha kwepolytetrafluoroethylene (PTFE) emulsion inoshanda sei yakakosha parameter inovimbisa kugadzirisa kwayo uye kushanda kwayo. Zvigadzirwa zvemainstream zvinowanzochengetedza yakagadzikana isina kusimba alkaline pH ye8.0-10.5 . Kuchinja kwepH kunogona kukonzeresa kuita kweketani kubva kudiki kusvika kune macro mazinga, zvichikanganisa kugadzikana kwehurongwa (semuenzaniso, hupenyu hwesherufu, anti-coagulation kugona) uye kuita kwekuisa pamuviri (semuenzaniso, permeability, yekupedzisira coating quality).

1. Migumisiro paKugadzikana

PTFE emulsion ndeye thermodynamically isina kugadzikana sisitimu iyo kugadzikana kwayo kunonyanya kuvimba ne electrostatic repulsion pakati pePTFE microparticles. pH inogadzirisa zvakananga iyi chiyero chakakosha.

Electrostatic Stabilization Mechanism (Zeta Inogoneka)

Munzvimbo ine alkaline isina kusimba, PTFE microparticles inova yakashata neadsorbing hydroxyl ions (OH⁻), ine Zeta inogona kusvika -50 mV kusvika -65 mV . Iyi yakasimba electrostatic repulsion yakakwana kukunda van der Waals masimba uye kuchengetedza zvimedu zvakapararira.Kana pH inodonha kusvika kune isoelectric point yePTFE (yakapoteredza pH 2.9-3.2), mhosva dzepamusoro dzinogadziriswa, Zeta inogona kusvika zero, uye emulsion inokurumidza kukanganisa uye inosangana nekugadzirisa kusingagadziriswi.

Kudzikamisa Mhedzisiro yeAlkaline Nzvimbo

Commerce PTFE emulsions inochengetwa isina simba alkaline kunyanya nekuda kwezvikonzero zvinotevera:

· Inhibition yekukura kwemicrobial : Nzvimbo isina kusimba alkaline inodzvanya kukura kwebhakitiriya, ichivadzivirira kubva pakudya ma surfactants uye kukanganisa emulsion.

Kudzvinyirirwa kwekuora kweasidhi : Iyo alkaline nharaunda inoregedza zvakasara acidic zvinhu kubva ku polymerization, kudzivirira kukora kwemidziyo uye kuparara kwekuita.

Ngozi dzeAcid Addition

Kana uchigadzirisa pH nemaasidhi akadai seacetic acid, iyo asidhi inofanirwa kuwedzerwa zvishoma nezvishoma mune zvidiki zvishoma nekunyorovesa uye pre-dilution. Kuwedzera nekukurumidza kana kuwandisa acidity kunozokanganisa chiyero chechaji cheiyo system uye zvakare kukonzera nekukurumidza emulsion kutyoka.

2. Migumisiro paImpregnation Performance

Impregnation inoda kuti emulsion inyatsopinda mu substrate uye igadzire yunifomu yejasi. pH inopesvedzera maitiro aya kunyanya nekushandura viscosity, wettability, uye pamusoro pechaji yehurongwa.

Permeability uye Adhesion

pH inokanganisa rheological maitiro emulsion. Iyo yakakodzera pH inogonesa kupararira uye capillary kupinda pane substrate pamusoro uye inodzivirira kuremara. Kunyanya kuderera kana kukwira pH kunogona kuderedza kunamatira.

Kiyi Parameter yeCo-Coagulation process

Mukugadzirisa zvinhu zvinosanganiswa, kugadzirisa pH kunobvumira kutonga kweZeta zvingangoita maviri kana anopfuura marudzi ezvimedu, zvichiita kuti yunifomu uye ibudirire co-coagulation kuburikidza ne electrostatic interaction. Semuenzaniso, kugadzirisa pH yekabhoni dema uye PTFE emulsion musanganiswa kusvika 7-10  inowana kugwinya kwakazara pasina kuwedzera coagulants.

PaAokai New Materials, pH kutonga mukati mekugadzirira uye kugadzira emulsion inovhara hupenyu hwese hwePTFE emulsion kubva pakuchengeterwa kusvika pakuita kwechigadzirwa chekupedzisira, zvichiita kuti zvive zvakakosha kushandisa zvizere zvakatanhamara zvePTFE zvinhu.

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane ruzivo rwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere zvinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-tembiricha mesh bhandi, mabhandi asina musono emichina yekubatanidza, jira rimwechete-sided PTFE, yakakwirira-tembiricha inodzivirira tembiricha, faibha inodzivirira girazi, tinofara kuonana nesu.
