Kutonhodza Mwero Migumisiro paPTFE Tape

Semugadziri wepakutanga wePTFE matepi ekupisa kwepamusoro, Jiangsu Aokai New Materials pano inotsanangura mabatiro enzira dzekutonhodza uye mwero wekutonhodza pakushanda kwematepi akarapwa ePTFE.

I. Essence yePTFE Crystallization Hunhu uye Kutonhodza Rate Regulation

Iyo PTFE substrate yeyakarapwa tepi yekupisa-yepamusoro ndeye semi-crystalline polymer, iyo inopinda nekukurumidza crystallization panguva yekutonhora mushure mekupisa. Chaizvoizvo, kutonhora kweyero ndiyo core process parameter yekudzora crystallinity yePTFE yakakwirira-tembiricha tepi: kunonoka kutonhora kunotungamirira kune yakakwirira crystallinity, nepo kukurumidza kutonhora kunoguma mune yakaderera crystallinity.

II. Mhedzisiro yeSlow Cooling paPTFE High-temperature Tepi

Pesvedzero paKushushikana Kwemukati  Kunonoka kutonhora kunogona kunyatso kudzikisa yasara yekupisa kushushikana mukati me tepi. Kana tepi yakatonhodzwa zvakasununguka mukati mechoto, iyo PTFE matrix uye girazi fiber skeleton vane nguva yakakwana yekugadzirisa shrinkage misiyano kuburikidza nekuzorora kweketani, kudzivirira kushushikana kwenzvimbo.

Iyo nzira inogamuchirwa zvakanyanya ndeyekutonhodza tepi zvakajairika muchoto kusvika 150-200 ℃ usati waiburitsa kunze kuti itonhodze mweya. Iyi inononoka kutonhora maitiro inocheka pasi kushushikana kwemukati zvinobudirira uye inodzivirira coating delamination uye kutsemuka.

Kufurira paDimensional Kugadzikana  Kunonoka kutonhora kunovandudza zvakanyanya kugadzikana kwedimensional. Munguva inononoka kutonhora, PTFE molecular cheni inoronga mune yakajairwa crystal lattices zvakakwana, ichigadzira yakakwirira crystallinity uye yakanyatsogadzirwa kristaro tsanga, iyo inovimbisa kugadzikana kwekupedzisira zviyero.

Kuderera kwekushisa kudiki kuchaitika pasi pekushisa kwakanyanya mukushandiswa chaiko, saka zvinokurudzirwa kuchengetedza 1% -2% margin panguva yekushandisa. Kunonoka kutonhora kunogonesa kudzikama shrinkage ine kushoma kwasara deformation.

Pesvedzero paAdhesive Performance  Inononoka kutonhora ine mbiri mbiri pane adhesion pfuma. Kune rumwe rutivi, inobvumira iyo inonamira layer kuti ipedze kuyambuka-kubatanidza uye kushushikana kuzorora zvizere, kuchengetedza yakagadzikana yekubatanidza simba. Kune rimwe divi, yakakwirira crystallinity inowedzera kuomarara kwepamusoro kwePTFE substrate, zvichikonzera kushushikana kwakanyanya pane bonding interface pasi pekupeuka simba.

III. Mhedzisiro yeKukurumidza Kutonhodza paPTFE Matepi epamusoro-tembiricha

     Kufurira paKushushikana Kwemukati  Kukurumidza kutonhora ndicho chikonzero chikuru chekunyanya kushushikana kwemukati. Kudzima kwakananga mushure mekunyura kunogadzira musiyano mukuru wetembiricha pakati pePTFE matrix uye girazi faibha furemu, ichigadzira ipapo shrinkage kusagadzikana uye nyore kugadzira mitswe yakanaka.

Iro repamusoro rinodzikira uye rinoomesa nekukurumidza apo iyo yemukati musara inoramba ichiwedzerwa, ichigadzira iyo yekupisa yekushushikana mamiriro ekunetsa kwekunze uye kumanikidza kwemukati, izvo zvinokonzeresa kuputika tepi.

Kupesvedzera paDimensional Kugadzikana  Kukurumidza kutonhora kunoshandura iyo crystallization peak kudzikisa tembiricha uye inoderedza crystallinity ine isina kukwana crystal chimiro. Iyo tepi inoramba iri mumamiriro echando asina kuenzana mushure mekudzima. Sekondari crystallization uye post-shrinkage inogona kuitika pasi pekuzotevera shanduko yekushisa, zvichitungamira kune zvishoma nezvishoma dimensional kutsauka.

Kupesvedzera paAdhesive Performance  Kukurumidza kutonhora kunovharidzira kuzere kuchinjika-kubatanidza kweadhesive layer. Iyo inonamira inoomeswa nechando isati yagadzira yakazara-yakabatana network, zvichikonzera kudzikira kwesimba rekubatanidza uye tembiricha kuramba.

Pasi pekudzokorora kutonhora uye kupisa bhasikoro, kupisa kwekuwedzera musiyano pakati pePTFE substrate uye adhesive layer inogadzira kushushikana kwemukati, kukurumidza kunama kuchembera uye kubvisa, uye zvakanyanya kunetesa viscosity kusimba.

IV. Kufananidzwa Kweakasiyana Kutonhodza Nzira

 

Kazhinji, kutonhora kunononoka uye yunifomu ndiyo musimboti wepashure-kurapa kurapwa kwePTFE yakakwirira-tembiricha matepi. Zvinokurudzirwa kutora mu-choto kutonhora kwechisikigo mushure mekupisa, uye kubvisa matepi ekutonhodza mhepo kusvika kune tembiricha yekamuri mushure mekunge tembiricha yadonha pasi pe150-200 ℃. Kutonhora kusingaenzaniswi panguva yekugadzira kunokonzeresa kuderera uye pakupedzisira kukuvadza kunaka kwechigadzirwa.

Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida kuziva yakadzama paramita, mamiriro ekushandisa uye yakagadziridzwa mhinduro yezvizere-yakatevedzana zvigadzirwa zvinosanganisira PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-temperature tepi, PTFE high-temperature mesh bhandi, seamless fusing muchina bhandi, single-sided PTFE jira, tembiricha inodzivirira inotakura bhandi, ndapota chengetedza tembiricha inotakurisa
