Chemical Corrosion Resistance yePTFE High-Temperature Fabric - Izvo Zvainomira uye Zvazvisingaite

Mumiti yemakemikari, mitsara ye electroplating, uye semiconductor machira, machira emidziyo uye mabhandi ekutakura anotarisana nekurwiswa nguva dzose kubva kumakemikari ane hukasha. PTFE high-temperature jira (fiberglass jira rakaputirwa nepolytetrafluoroethylene) rinowanzotaurwa chaizvo nekuda kwekusanzwisisika kwaro kemikari inertness. Asi kuramba 'kunenge kwepasi rose' hakusi 'pasi rose' - zvinhu zvishoma zvine hukasha zvinogona kukurwisa, uye tembiricha inoita basa rakakosha.

Aokai PTFE yakaedza PTFE jira kurwisa mazana emakemikari. Gwaro iri rinotsanangura zvarinorambira, zvekudzivisa, uye kuti tembiricha inokanganisa sei kuita basa.

Yese Performance Profile - Pedyo-Universal Chemical Inertness

PTFE high-tembiricha jira rinozvirumbidza zvakasarudzika kemikari corrosion kuramba, iri pakati pepamusoro tier yezvinhu zvakajairika zveinjiniya. Ichi chepakati chivakwa chinobva kune yekunze polytetrafluoroethylene coating, iyo inoumbwa yakasimba kabhoni-fluorine (CF) zvisungo zvinoramba makemikari kurwisa.

Iyo fiberglass substrate iri pazasi haina kemikari inert - asi chero bedzi iyo PTFE yekupfekedza ikaramba yakasimba, jira rinoita sechinhu chinenge chine inert. Patembiricha yekushanda nguva dzose, jira rePTFE rinoramba rakagadzikana kurwisa huwandu hwakawanda hweasidhi yakasimba, alkali yakasimba, organic solvents, uye oxidizing agents.

Yakakura Range yeResistant Media - Izvo PTFE Fabric Inogona Kubata

Pakupisa kwekushanda nguva dzose, zvinhu zvinoramba zvakagadzikana zvakanyanya kurwisana nehuwandu hwemaasidhi akasimba, alkalis yakasimba, organic solvents, uye oxidizing agents.

1. Asidhi yakasimba

Concentrated sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, uye aqua regia (musanganiswa we nitric uye hydrochloric acids inonyungudutsa goridhe) - PTFE inotsungirira zvose. Hapana kuomarara kunoyerwa kunoitika.

2. Alkali yakasimba

Sodium hydroxide (NaOH) uye potassium hydroxide (KOH) mhinduro haina mhedzisiro yakaipa pakupisa kwekamuri. Resistance inoenderera kune yakawanda alkaline nharaunda.

3. Organic solvents

PTFE hainyunguriki mune zvese zvinonyungudutsa zvinozivikanwa. Iyo haizozvimba kana kunyungudika kana yaiswa kune ketoni, madoro, ethers, mahydrocarbon, chlorinated solvents, kana chero chimwe chikamu chinonyungudutsa.

4. Oxidizing agents

Inoratidza kushivirira kwakanyanya kune zvine simba oxidizer senge hydrogen peroxide (H₂O₂) uye permanganate.

5. Zvimwe zvinhu

• Hydrolysis-resistant - isingabatwi nemvura kana mupfu

• Kudzivirira mamiriro ekunze - UV uye kuratidzwa kwekunze kunokonzeresa kuderera

• Mafuta-anodzinga uye asina-tsvimbo - pasi pasi simba rinodzivirira kunamatira

• Kunyura kwemvura - zvinobudirira zero (<0.01%)

Kunze – Makemikari Kuchenjerera Nezve

PTFE haidziviriri pasi rose. Inopindirana nenhamba diki yemakemikari anoshanda zvakanyanya pasi pemamiriro akanyanya, ayo anoda kutariswa kwakanyanya panguva yekusarudza zvinhu.

Aokai PTFE inosimbisa kuti izvi zvisiri izvo hazviwanzo asi zvakakosha kuziva:

H3: Yakanyungudutswa alkali simbi

Yakanyungudutswa sodium (Na), potassium (K), uye lithium (Li) inoputsa carbon-fluorine zvisungo mukati mePTFE, zvichiita kuparadzwa zvachose. Uyu ndiwo musimboti uri kuseri kwesodium-naphthalene etching yePTFE pamusoro kurapwa.

H3: Yakanyanya reactive halogen makomisheni pasi pekupisa kwakanyanya uye kudzvanywa

• Chlorine trifluoride (ClF₃)

• Oxygen difluoride (OF₂)

• Fluorine gasi (F₂) pane yakakwirira tembiricha uye kumanikidza

Izvi zvinogona kuita pamwe kana kutopisa PTFE pasi pemamiriro akanyanya.

H3: Yakanyungudutswa maalkali akasimba pakupisa kwakanyanya

Yakanyungudutswa sodium hydroxide (NaOH) kana potassium hydroxide (KOH) pamusoro pe 300°C zvishoma nezvishoma inokonzera PTFE. Pane tembiricha yemumba, hapana mhedzisiro.

H3: Chiyeuchidzo chakakosha - kukanganisa kwekuvhara kunofumura fiberglass

Izvo zvipingamupinyi zviri pamusoro zvinoshanda chete kune pamusoro pePTFE coating. Kana iyo yekupfeka ikakweshwa, yakakuvadzwa, kana ine pinholes, iyo iri pasi pefiberglass substrate ichaburitswa pachena. Fiberglass ine kushomeka kwekuramba kune:

• Hydrofluoric acid (HF) - inokurumidza kunyungudutsa magirazi egirazi

• Kupisa kwakaiswa alkalis - kurwisa girazi

Ichi ndicho chikonzero kuchengetedza coating kutendeseka kwakakosha kune kemikari sevhisi. Nezvekushandisa zvinosanganisira HF, funga yakachena PTFE firimu panzvimbo.

Kufurira kweTembiricha pane Chemical Resistance

Tembiricha inoshanda sechinhu chakakosha chinotonga makemikari kuramba. Mukati metembiricha yetembiricha yenguva refu (kazhinji -70°C kusvika 260°C), kugadzikana kwemakemikari ePTFE hakutombokanganiswi.

Zvisinei, tembiricha yakadzikama inodarika 260°C ichaita:

• Zvishoma nezvishoma kuderedza PTFE kwakaita kemikari inertness

• Ita kuti zvinyorwa zvinyanye kukukurwa nezvinhu zvakanyanyisa zvataurwa pamusoro apa

• Kurumidza kushatisa kupisa, kugadzira nzvimbo dzisina simba apo kurwisa kwemakemikari kunogona kutanga

Aokai PTFE bvunzo data: Pa 250 ° C inoramba ichiratidzwa, PTFE jira rinochengeta > 90% yemakemikari ekupikisa zvivakwa mushure memazuva mazana maviri. Pa280 ° C, kushanda kunoderera zvakanyanya mukati memavhiki.

Nezvezvishandiso zvine tembiricha yepamusoro (>260°C) uye kuratidzwa kwekemikari, bvunza ruzivo rwehunyanzvi kana kuti kuyedza-chaiwo.

Pfupiso - Nguva Yekusarudza PTFE Fabric yeMakemikari Mamiriro

Aokai PTFE inopa PTFE-yakavharwa machira ekuda makemikari nharaunda. Zvekushandisa zvinoda HF kuramba kana kunyanyisa kemikari chokwadi, tinokurudzira kuyedza pasi pemamiriro ekushanda chaiwo kana kushandisa magiredhi emufirimu ePTFE akachena. Bata isu nekemikari yako chaiyo, tembiricha, uye nguva yekuratidzwa yekurudziro.

Izvi zvehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Material Technology Co., Ltd.

Kana iwe uchida kutsanangurwa kwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere chepodfolio, kusanganisira PTFE high-temperature machira, PTFE high-temperature adhesive matepi, PTFE mesh conveyor mabhandi, seamless fusing muchina mabhandi, single-sided PTFE yakavharidzirwa jira, inodzivirira kupisa-inodzivirira bhandi refayibha nzira dzinotevera:
