Ko Kurapwa Kwemoto Kunogona Kugamuchirwa Kugadziriswa Kwepamusoro kwePTFE Substrates? Kufananidza kweMigumo neCorona uye Plasma Kurapa
Tsanangudzo na PTFE High-Temperature Fabric Manufacturers
I. Kugoneka kweFlame Treatment paPTFE
Kushanda kweIndasitiri: Muchidimbu, kurapwa kwemurazvo kunogona kuona kushandurwa kwepamusoro kwePTFE. Zvisinei, haiwanzogamuchirwi mumaindasitiri, uye kushanda kwayo kwakaderera zvikuru kukurapa kweplasma. PTFE yakakwirira-tembiricha machira vagadziri havaikurudzire seyakajairwa nzira.
Njodzi Dziviriro: PTFE inokonzeresa kuora kwekupisa pasi petembiricha yemoto, ichiburitsa magasi ane muchetura akadai sehydrogen fluoride uye perfluoroisobutylene, ayo anoisa njodzi dzakakomba kuvashandi nenharaunda. Matanho akasimba ekudzivirira anosungirwa.
Performance Limitation: Kunyangwe pasi pekutonga chaiko, flame oxidation inogona chete kusimudza pamusoro pesimba rePTFE kubva pa18 mN/m kusvika 30–35 mN/m. Kukuvadzwa kwekupisa pamusoro pepamusoro kunoumba nyore muganhu usina simba, zvichiita kuti pave nekugadzirisa zvishoma kwekuita kwekunamatira.
II. Kuenzanisa kweKushanda Mechanism yeMatatu Matanho
Kurapa kweFlame: Kuvimba nekupisa kwepamusoro-tembiricha oxidation pamusoro pe1000 ° C kubva mumurazvo, inowana etching zvishoma uye inounza mashoma emapoka ane okisijeni, asi anoratidza kusashanda zvakanaka mukupwanya akatsiga C-F zvisungo.
Corona Kurapa: Kuyerera kwepamusoro-voltage kunogadzira ozone uye inoshanda okisijeni, ichibatanidza kubhomba kwemuviri nekunyorova oxidation. Nekuda kwekushomeka kwesimba, haitombodambura mabhondi akatsiga eC-F.
Plasma Kurapa: High-energy particles, maerekitironi uye emahara radicals anotsemura zvakananga C-F zvisungo, uye graft polar mapoka senge hydroxyl, carboxyl uye amino mapoka kuti awane makemikari grafting, achiunza yakadzika pasi pekugadzirisa.
Surface Energy uye Adhesion Strength: Low-pressure oxygen plasma inogona kusimudza PTFE pamusoro pesimba kusvika ku50-65 mN / m nekunamatira simba rinosvika 8-15 MPa. Murazvo uye kurapwa kwekona kunongowedzera simba repamusoro kusvika ku30-38 mN/m, uye simba rekunamatira rinowanzo kuderera kupfuura 2 MPa, kazhinji inoperekedzwa nekutadza kwechiso.
Uniformity: Kurapa kwePlasma (kunyanya mumakamuri akadzika-kumanikidza vacuum) inopa kurapwa kwakafanana pamusoro pepamusoro pese. Kurapa kweCorona kwakakodzera chete mafirimu akafuratira uye inogadzira nzvimbo dzemapofu dze 3D workpieces. Kurapa kwemoto kunokonzeresa kupisa kwenzvimbo kana kusakwana kurapwa pazvikamu zvakaoma-maumbirwo.
Kuchembera Kugadzikana: Plasma-yakagadziridzwa maseketi anoramba akagadzikana kwemavhiki akati wandei kusvika kumwedzi, uye kugadziridzwa kwegraft kunowedzera nguva yakakodzera. Mhedzisiro yekurapa kwemoto inoora mukati memaawa akati wandei kusvika mazuva. Kurapa kweCorona kunorasikirwa nekushanda mukati memakumi emaminitsi kusvika kumaawa akati wandei nekuda kwekukurumidza kudzokororwa kwepamusoro mamorekuru cheni.
IV. Kuongorora Kwakazara uye Inokurudzirwa Solutions
Mhedzisiro Chiyero: Kurapwa kwePlasma > Kurapa kweFlame > Kurapa kweCorona. Kurapwa kweCorona hakuna zvakunobatsira kuPTFE. Kurapwa kwemoto kuri nani zvishoma pane kurapwa kwekorona, nepo paine gedhi rekuita rekuita kana richienzaniswa nekurapa kweplasma.
Kusarudzwa Kwemaitiro: Kune zvakavimbika zvinodikanwa zvekunamatira, yakaderera-kudzvanywa plasma kurapwa kana sodium-naphthalene kemikari etching ndiyo yekutanga sarudzo. Atmospheric pressure plasma inogona kutariswa inline film processing. Kurapa kwemurazvo kunongogumira pakuongorora kwakanyanyisa kana midziyo yeplasma isipo uye PTFE bonding inodiwa, nekutonga kwakasimba pamusoro petembiricha uye mhepo. Kurapwa kweCorona hakukurudzirwe kuti PTFE activation.
Chengetedzo Pazasi Mutsetse: Chero maitiro ekupisa kwepamusoro akaiswa kuPTFE anofanirwa kunge akashongedzerwa nemagetsi ekuona ehydrogen fluoride nemamwe magasi ane muchetura pamwe nekumanikidzirwa kufefetera masisitimu kudzivirira kuunganidzwa kwezvigadzirwa zvekuora zvine chepfu uye kuvimbisa kuchengetedzwa kwekushanda.
Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Material Technology Co., Ltd.
Kana iwe uchida kudzidza zvakadzama zvinotsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvezvizere-range zvigadzirwa zvinosanganisira PTFE high-temperature machira, PTFE high-temperature adhesive matepi, PTFE high-temperature mesh mabhandi, seamless fusing muchina mabhandi, single-sided PTFE machira, yakakwirira-tembiricha inodzivirira fiber bhandi ndapota taura nesu kuburikidza nenzira dziri pasi apa:
