Sei Sintering Inonyanya Kukosha Nhanho Kuona Yekupedzisira Kuita kwePTFE Yakavharwa Fiberglass Fabric?

KuJiangsu Aokai Advanced Materials Technology Co., Ltd., iyo sintering yePTFE yakavharidzirwa fiberglass machira anoonekwa se 'moyo nemweya' wekugadzirwa. Iyo inonyanya kushandura yakanamatira mumuviri PTFE zvimedu kuita inoenderera firimu layer ine yakasarudzika maitiro, kuona kana PTFE machira anogona zvechokwadi kuva yakakwirira-inoshanda composite zvinhu. Izvi zvinoongororwa zvakadzama kubva pamativi mana pazasi.

1. Microstructural Shanduko: Kubva pa 'Particle Stacking' kuenda 'Inoenderera mberi Firimu Magadzirirwo'

Mushure mekuita pamuviri uye kuomeswa, PTFE inongove yakasununguka, zvimedu zvakanaka zvakaiswa pamusoro uye mukati me interstices ye fiberglass substrate. Panguva ino, jira rakapera harina simba rinoshanda, uye iyo yekupfekedza inoputika nyore nekukwesha kudiki.

Basa reSintering :Pakupisa kwepamusoro kwe360-380 ° C, PTFE zvimedu zvinonyunguduka, kupararira, uye coalescence kuti iite dense, inoenderera, isina-porous firimu inoputira zvizere fiberglass. Pasina shanduko iyi, jira harigone kuzadzisa siginecha yaro isiri-tsvimbo, makemikari-resistant, uye magetsi insulating zvivakwa.

2. Kusarudza Bond Simba uye Mechanical Properties

Fiberglass uye PTFE zvinhu zvakasiyana zvakasiyana. Kusakwana kwekubatana kwechiso kunotungamira mukuputira delamination, kuputika, kana kusvuuka panguva yebasa.

Interfacial Fusion uye Crystallinity Control : Panguva yekunyungudutsa, PTFE yakanyungudutswa inopinda uye inopinda mukati meiyo micropores uye yakaoma pamusoro pefiberglass, ichigadzira mechanic kupindirana. Zvichakadaro, chaiyo sintering tembiricha uye inodzorwa kutonhora mwero inodzora crystallinity yePTFE. Tsvagiridzo inoratidza kuti jira rePTFE riri pasi-sintered rine yakaderera crystallinity uye isina kusimba zvakanyanya, ine machira anokurumidza kupera nekupeta kana kubvongodzwa. Iyo chete yakaomesesa inodzorwa sintering process inovimbisa yakanakisa peel simba, kusimba kusimba, uye flex hupenyu.

3. Kugadzira Final Density uye Protective Barrier

Fiberglass pachayo ine brittle, haina kupfeka-inomira, uye inotapukirwa nehydrolysis. Kuita kwakatanhamara kwePTFE yakavharwa jira rinotsamira zvachose pane sintered PTFE inodzivirira layer.

Kubvisa Kukanganisika uye Kugadzira Chipingamupinyi :Sintering fuse uye inobvisa madiki pinholes, mabhuru emhepo, uye zvimwe zvakakanganisika kubva kumaitiro apfuura, kugadzira chinhu chakakosha 'chidziviriro chezvombo.' Ichi chipingamupinyi chakaomarara chinogonesa kuramba kwenguva refu kumaasidhi akasimba, alkali, uye organic zvinonyungudutsa, apo ichipa yepamusoro isiri tsvimbo uye magetsi ekudzivirira kuita. Muchidimbu, sintering mhando inotsanangura zvakananga muganho wekushandisa wejira - ingave yeyakajairwa-chinangwa-isina-tsvimbo mabhandi ekutakurisa kana aerospace-giredhi insulation zvinhu.

4. Kunyanya Sensitivity yeSintering Parameters kune Product Quality

Sintering ine yakamanikana uye yakanyanya kuoma hwindo rekuita muPTFE kugadzirwa kwemachira; kutsauka kudiki mumaparamita kunotungamira kune misiyano inoshamisa mukuita.

Chaiyo Chiyero cheTembiricha uye Nguva :Tembiricha isina kukwana kana kureba kwenguva zvinoguma ne 'under-sintering': PTFE inotadza kunyatsoita firimu-fomu, ichisiya yakasununguka, yakacheneruka, isina kusimba uye isina kusimba makemikari kuramba. Tembiricha yakawandisa kana nguva yekugara inokonzera kupisa kwePTFE, kuburitsa utsi hune muchetura, kuderedza simba re substrate, uye kuita kuti jira rive brittle uye yero, zvichiita kuti isashande.

Decisive Pesvedzero yeKutonhodza Mwero : Mwero wekutonhodza mushure mekunyura unosarudza iyo crystalline morphology uye crystallinity yePTFE. Kukurumidza kutonhora kunogadzira yakaderera-crystallinity, jira rinochinjika zvakanyanya rakanakira kushandiswa kwekupeta. Kutonhora kunononoka kunoumba yakakwirira-crystallinity, yakakwirira-kuomarara, jira risingapfekeri rakakodzera kuiswa chisimbiso.

Mhedziso

Kuburikidza ne 'thermal history,' iyo sintering yakanyatsodzorwa inobudirira PTFE kunyunguduka, kuumbwa kwefirimu, crystallization, uye interfacial bonding nefiberglass, kushandura chigadzirwa chisina kusimba chehafu-chakapedzwa kuita chepamusoro-chinobatanidzwa zvinhu. Iyo inonyanya kutarisisa tembiricha kuramba, kugadzikana kwemakemikari, simba remuchina, kuvharwa kwemagetsi, uye zvimiro zvepamusoro zvePTFE yakavharwa fiberglass jira. Naizvozvo, sintering pasina mubvunzo ndiyo nhanho inonyanya kukosha mukuita kwese kwekugadzira, uye tekinoroji yayo inomiririra yakanangana neiyo yakakosha tekinoroji kukwikwidza kwePTFE vanogadzira machira.

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai Advanced Materials Technology Co., Ltd.

Kuti uwane ruzivo rwakadzama, mamiriro ekushandiswa, uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere - zvinosanganisira PTFE yakavharidzirwa fiberglass jira, PTFE yakakwirira-tembiricha tepi, PTFE yakavhurika-mesh mabhandi ekutakurisa, seamless fusing muchina mabhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira inodzivirira bhandi, uye isu girazi rinodzivirira bhandi, uye isu tisina girazi
