Kudzora Kwazvo kwePTFE Coating Ukobvu muKugadzirwa Kwemucheka

Senyanzvi sosi inogadzira PTFE yakakwirira-tembiricha machira, Jiangsu Aokai Zvitsva Zvishandiso inokupa tsananguro yakadzama. Kune nzira yekupfekedza machira egirazi fiber (kana yakafanana fiber felts / textiles) nePTFE emulsion, musimboti wekudzora ukobvu wakafanana neyakajairwa dip-coating nzira. Kuoma kukuru kuri mune porous uye isina kuenzana chimiro chefiber substrates. Naizvozvo, musimboti wekudzora ukobvu ndeyekuenzanisa iyo micro liquid absorption kugona uye macroscopic process paramita ine yakanyanya kurongeka.

1. Emulsion Formula: Inotemesa hupamhi hwehwaro hwega hwega hwekuputira layer

Solid content uye viscosity : Gamuchira yakaderera solid content dispersion (eg 45%) kuti uite jira rakatetepa papasi uye kuderedza njodzi yekupwanya. Emulsion viscosity ndiyo kiyi yekugadzirisa fluidity uye coating pickup chiyero.

2. Impregnation Process: Dynamic mechanical balance

Kusimudza / Kudzvanya kumhanya : Iyo yekumhanyisa inosarudza kunyorova kwefirimu ukobvu hunoumbwa nechiyero chegiravhiti uye viscous simba. Kumhanya kwepamusoro kunotakura emulsion yakawanda uye inoumba firimu rakanyorova rakanyorova.

Impregnation nguva uye faibha pretreatment : Ita shuwa kunyorova kwakazara uye kupinda kwefiber. Kusati kwaiswa, maburrs uye tsvina pafiber surface inofanirwa kunyatsocheneswa kuti ivimbise kupfekedzwa kweyunifomu uye kusimba kwekubatana.

Multi-pass coating uye post-kurapa : Wana chinangwa ukobvu nekuunganidza zvishoma nezvishoma. Iri ndiro zano repakati rekusvika kune ukobvu hunodiwa, kazhinji uchitevera kutenderera kweakawanda impregnation - drying - sintering . Iyo yakakurudzirwa imwe-pass coating ukobvu inodzorwa mukati me 0.01mm ~ 0.08mm.

·  Kuomesa : 100 ~ 150 ℃ kubvisa zvachose unyoro.

Kubika  : 280 ~ 290 ℃ kubvisa surfactants. Kusaenzana kuomesa uye kubheka kunokonzera kuputika, mabhubhu kana pinholes pamucheka.

Sintering  : 360 ~ 390 ℃, kubata kwe30 ~ 90 masekondi. Sintering yakakosha pakugadzira coating. Kunyanya kupisa kwekushisa kunotungamirira kuhutano husina kunaka pakati pekuputira uye fiber; kunyanya kupisa kwepamusoro kunogona kukonzera kuora kwe resin.

3. Zviitiko zvezvakatipoteredza: Zvinokosha zvinopesvedzera zvinhu

Humidity : Humidity yeAmbient inofanira kunyatsodzorwa pa40 % -60% RH . Kunyanya kuderera humidity kunokonzera ganda repamusoro uye kusakwana kwemukati kupinza; hunyoro hwakanyanya hunogona kukonzera kudonha, mapini uye kuderera kunamatira.

Hutsanana hwewekishopu : Nyatsodzora hutsanana hwewekishopu kudzivirira zvimedu zvinofambiswa nemhepo kuti zvisadonha mutangi rekuisa pamuviri kana kunamatira kune isina kuomeswa firimu, izvo zvinokonzeresa kuremara kwepamusoro.

4. Mazano Anoshanda & Unhu Hwakavharwa-Loop Control

Nhungamiro yekugadzira : Zvinokurudzirwa kutora zano rekushomeka kwakadzika + kuwanda impregnation inopfuura  kuti unyatso kudzora iyo yakazara coating ukobvu nekugadzirisa impregnation nguva. Zvichakadaro, simbisa pre-kurapwa uye post-kurapwa maitiro, ayo ari hwaro hwemhando yepamusoro yekupfeka.

Troubleshooting : Kana kuputika kwekuputira kukaitika mushure mekupisa, tarisa kana single-pass coating yakanyanya kukora kana kuomesa nekukurumidza; kana coating adhesion isina kukwana, ongorora fiber pamusoro pehutsanana pamwe nekupisa tembiricha uye kubata nguva.

Hunhu hwakavharika-loop system : Gadzira yakakwana yekugadzira logic:  process parameter control → Pa-line-chaiyo-nguva yekutarisisa → Yakapedzwa chigadzirwa chekuongorora nhamba → Maitiro ekugadzirisa mhinduro .
PTFE inregnation inonetsa physicochemical process ine multi-variable coupling. Yakagadzika ukobvu huroyi hunogona kuwanikwa chete nekuvaka yakamisikidzwa yekudzora sisitimu inovhara emulsion fomula, maitiro maparamendi uye mamiriro ezvakatipoteredza, pamwe chete nenzira dzakafananidzwa dzekuedza.

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

Kana iwe uchida ruzivo rwakadzama pamusoro pehunyanzvi parameters, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvemutsetse wedu wechigadzirwa unosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless fusing muchina bhandi, single-sided PTFE yakavharidzirwa machira, yakakwirira-temperature inomira, ndapota inodzivirira fiberglass bhandi. inzwa wakasununguka kutibata nesu:

Isu tinogara tichitsigira huzivi hwehunyanzvi uye kuvimbika, uye tinoyedza kukupa iwe-yekumira-yega mhinduro uye inofunga mushure mekutengesa sevhisi!
