Kudzora Kwazvo kwePTFE Coating Ukobvu muKugadzirwa Kwemucheka

Senyanzvi sosi inogadzira PTFE yakakwirira-tembiricha machira, Jiangsu Aokai Zvitsva Zvishandiso inokupa tsananguro yakadzama. Pakupfekedza machira egirazi faibha (kana machira akafanana efiber kana machira) ane PTFE 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 yakasimba 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 inofanira 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 zvinopeperetswa 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 inyatso 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 yekutarisa → Yakapedza 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 paramita uye mamiriro ezvakatipoteredza, pamwe chete neakaenzana nzira dzekuedza.

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

Kana iwe uchida ruzivo rwakadzama pamusoro pehunyanzvi paramita, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa mutsara wedu unosanganisira PTFE high-temperature jira, PTFE high-temperature adhesive tepi, PTFE high-temperature mesh bhandi, seamless fusing machine bhandi, single-sided PTFE yakavharidzirwa jira, high-temperature temperature belt, high-temperature; inzwa wakasununguka kutibata nesu:

Isu tinogara takatsigira huzivi hwehunyanzvi uye kuvimbika, uye tinoyedza kukupa iwe-yekumira-yega mhinduro uye ine kufunga mushure mekutengesa sevhisi!
