Maitiro Ekuyedza PTFE Emulsion Hunhu: 6 Core Indicators & Nzira

PTFE emulsion - inozivikanwawo se PTFE dispersion - ndiyo mbishi yekuputira fiberglass jira kugadzira. PTFE high-temperature jira , matepi, uye mabhandi. Kana iyo emulsion mhando yakadzimwa, chigadzirwa chekupedzisira chichava nekusashanda kwetsvimbo, kusaenzana kupfekedza, kana kutadza nguva isati yakwana.

Asi unoziva sei kana batch yePTFE emulsion yakanaka? Iwe zviedze.

Aokai PTFE yakashandisa uye yakaedza PTFE emulsions kwemakore. Gwaro iri rinobata zvitanhatu zvekuyedza zviratidzo - yakasimba yemukati, pH, particle size, viscosity, kugadzikana, uye chitarisiko - nemaitiro akajairwa uye maitiro ekugamuchira.

Solid Content - Iyo Yakanyanya Basic Indicator

Solid yemukati inobata zvakananga kuita kwechigadzirwa uye hupfumi hwekushandisa (yakakora coating inoda yakakwira solids).

Nzira dzekuyedza dzinozivikanwa:

Maitiro ekugamuchira:

• Per standard T/FSI 067-2021: Solid content inodiwa kuti idzokororwe kuisirwa PTFE concentrate i60±2%

• Chaiyo pane-saiti yekudzora chiyero: 60 ± 0.5% (yakasimba kushivirira kune inowirirana coating)

pH Kukosha - Kugadzikana Indicator

pH kukosha inokanganisa kuchengetedza kugadzikana, kuora, uye kuenderana nezvimwe zvinhu.

Kuedza nzira: Girazi Electrode Method (Yakananga Sarudzo) - kuyera uchishandisa pH mita ine girazi electrode calibrated kuburikidza maviri-poinzi kana matatu-mapoinzi calibration. Iyi ndiyo inonyanya kushandiswa chiyero nzira.

Maitiro ekugamuchira:

• Per T/FSI 067-2021: pH range 9.0 - 11.0

• Kuchinja kwepH kunowanzoratidza kusagadzikana kwehurongwa kana kemikari kuita kwakaitika (semuenzaniso, hydrolysis ye surfactant)

• Kutevera kwenguva refu kwepH kuchinja kwakakosha pakutonga kugadzikana kwemakemikari emulsion

Nei pH yakakosha: PTFE emulsions inogadziriswa ne fluorinated surfactants, iyo inoda alkaline mamiriro (pH> 8) kuti arambe achishanda. Kana pH inodonha pasi pe8, iyo emulsion inogona kudonha.

Aokai PTFE inokurudzira kuyedza pH pane yega yega dhiramu inouya uye pamwedzi panguva yekuchengetedza. Kudonha kamwe kamwe kubva ku10.2 kusvika ku8.5 kwemavhiki maviri kunoratidza kuti emulsion inokanganisa uye inofanira kushandiswa pakarepo kana kurambwa.

Particle Size & Particle Saizi Distribution

Saizi uye kugovanisa kufanana kwePTFE zvidimbu zvekutanga zvine simba rekuita pane firimu-kugadzira zvivakwa, permeability, uye yekupedzisira chigadzirwa kuita.

Nzira dzekuedza:

Makiyi ekuongorora zviratidzo:

• D50 (yepakati dhayamita) - yakajairika renji yePTFE emulsion: 0.1-0.3 microns

• Particle saizi yekugovera hupamhi - yakamanikana iri nani kune inowirirana coating

• D10 uye D90 - inoratidza kupararira kwekugovera

Nhungamiro yekugamuchira: Pazvizhinji zvekuputira zvikumbiro, D50 inofanira kuva pakati pe0.15 ne0.25 μm ne 90% yezvikamu mukati me ± 0.1 μm yezvinoreva.

Viscosity - Kugadzirisa Kushanda

Viscosity inoratidzira mafambiro ekuyerera, inokanganisa yakananga kukoira uye impregnation maitiro.

Nzira dzekuyera dzakajairika:

Maitiro ekugamuchira:

• Per T/FSI 067-2021: Viscosity range 12.0 – 30.0 mPa·s (pa25±1°C)

• Viscosity iyo yakanyanya kuderera → isina kuenzana coating, inodonha

• Viscosity yakanyanyisa → kusapinda mufiberglass, kunoda dilution

Chishandiso checherechedzo: Pakunyudzwa kwejira refiberglass, tarisiro ye viscosity inowanzoita 15-20 mPa·s. Kana viscosity ichidonha, gadzirisa nemvura yakasvibiswa (kudzikisa) kana kuwedzera thickener (kusimudza).

Kugadzikana Kuongorora - Kuchengetedza & Kuvimbika Kwekutakura

Kugadzikana kwekuongorora kunovimbisa kuti emulsion inoramba yakafanana panguva yekuchengetedza uye kutakura. Inokurumidza kuyedza nzira dzinoshandiswa kutevedzera kwenguva refu mamiriro.

Kupasa/kufoira maitiro:

• Hapana inooneka delamination, sedimentation, kana gel kuumbwa

• Viscosity shanduko <10% kubva pakutanga

• Particle size D50 shanduko <15%

Hutungamiri hwehupenyu hweSherufu: Pasi pekuchengetedza kwakakodzera (10-30 ° C, yakavharwa), PTFE emulsion inowanzochengetedza kugadzikana kwemwedzi 6-12. Kana centrifuged test inoratidza> 5% sediment, rasa batch.

Kuongorora Kwekuonekwa - Kurumidza Batch Consistency Check

Ongorora nemeso sampuli pasi pechiedza chechisikigo.

Chitarisiko chinogamuchirika: White or light yellow emulsion, yunifomu, isina abnormalities senge delamination, gel mapundu, kuumbwa kweganda, kana kunaya kuri pachena.

Chekutarisa:

• Kusviba → kusvibiswa kunogona kuitika kana kushatisa kupisa

• Ganda riri pamusoro → kuomeswa kana kugadzika zvishoma

• Mapundu kana grit → coagulated polymer (yakaipa)

• Mvura yakachena pamusoro → sedimentation yaitika

Pfupiso - Sarudza Maitiro Ekuyedza Kubva pane Chishandiso

Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
