PTFE high-temperature jira (PTFE-yakavharidzirwa fiberglass) yakanaka chete seyakagadzirwa inoshandiswa kuigadzira. Nepo PTFE iri yemhando yepamusoro-inoita polymer, tsvina pachikamu chemolecular inogona kushatisa zvimiro zvayo.
'Raw material purity' pano inoreva zvinhu zviviri: kuchena kwePTFE raw materials (residual Initiators, surfactants, low-molecular-weight polymers, metal ions) uye kuchena kwefiberglass finishing agents (saizi, mafuta ekuzora, zvinosvibisa kubva pakuruka).
Aokai PTFE inosarudza chete yakakwirira-kuchena mbishi zvinhu. Ichi chinyorwa chinotsanangura kuti tsvina inokanganisa sei zviyero zvitanhatu zvakakosha zvekushanda: kupisa kwekushisa, kusanamatira zvivakwa, magetsi ekudzivirira, simba remagetsi, chitarisiko, uye kuchengetedzwa kwemakemikari.
Heat Resistance uye Thermal Kugadzikana - Kusvibiswa Kunowedzera Kushatisa
Kupisa kupikisa ndicho chiratidzo chekushanda kwepamusoro-tembiricha jira.
1. Kusachena kunokonzera kuora kwekutanga kwemafuta
Residual Initiators, low-molecular-weight polymers, uye zvisina kucheneswa surfactants zvinoratidza kuderera kwakanyanya kwekushisa kwekuora tembiricha pane yakachena PTFE. Pasi pesevhisi yenguva refu-yepamusoro-soro (semuenzaniso, 260 ° C), tsvina iyi inoora uye carbonize kutanga, ichigadzira gasi rinoita kuti mabubbles, pinholes, blistering, uye delamination mukati mejasi.
2. Yakaderedza kuenderera kwekushanda kwekushisa
Acid kana alkaline byproducts kubva kutsvina yakaora inogona kuwedzera kukonzeresa kutsemuka kwePTFE molecular backbones, kudzikisa chaiyo tembiricha kuramba mwero wejira uye zvakanyanya kupfupisa hupenyu hwayo hwesevhisi. Chete yakakwirira-kuchena mbishi zvinhu zvinogonesa kugadzikana kwenguva refu kushanda mukati me260 ° C kusvika 300 ° C.
Aokai PTFE bvunzo data: PTFE jira rakagadzirwa kubva-yegiredhi-giredhi emulsion inoratidza inooneka yero mushure me100 maawa pa260°C. Mucheka wakagadzirwa kubva ku-high-purity emulsion unoramba usina kuchinja mushure memaawa 500 pane imwe tembiricha.
Kusina-tsvimbo kuita ndiyo musimboti wekushanda mukana wePTFE yakakwirira-tembiricha jira.
1. Kusaenzana pamusoro pesimba rekugovera
Iyo isiri-tsvimbo hunhu hwePTFE hunobva kune yayo yekupedzisira-yakaderera pamusoro pesimba. Kana inorganic particles, isina kunyungudutswa resin tsvina, kana mafuta anosvibisa aripo mune yakabikwa zvinhu, anozomira mukati kana mukati mejasi mushure mekunyunguduka, achigadzira isina kuenzana pamusoro pesimba uye kugadzira adhesion anchor point..
Zvishandiso zvakaita seanonamira uye zvinongedzo zvechikafu zvinowanzo kunamatira kutanga kubva kune aya mapoinzi uye pakupedzisira zvinogadzira nzvimbo dzakakura dzakasungwa panguva yekushanda. Yakakwirira yakasvibira zvinhu kuchena kunopa yakawedzera yunifomu uye dense coating ine yepamusoro kusunungurwa uye anti-stick mhedzisiro.
Kuchena chinhu chinosarudzira jira rinopisa repamusoro rinoshandiswa sematasi ekudzivirira magetsi.
1. Kukwira kwakanyanya mukurasikirwa kwedielectric
Ionic tsvina dzinosanganisira simbi ions, munyu, uye zvakasara zvinokonzeresa zvinoshanda sevatakuri vanochaja, zvakanyanya kuwedzera dielectric kugara uye dissipation chinhu uku ichideredza vhoriyamu resistivity. Izvi zvinoderedza kushanda kwe insulation.
2. Yakaderera breakdown voltage
Conductive contaminants senge simbi scraps uye carbonized spots zvinonangidzira minda yemagetsi uye zvinoita kuti pasave nekubuda, izvo zvinoderedza zvakanyanya kudonha kwemagetsi. Yakakwirira-kuchena PTFE inosungirwa kuchengetedza yakanakisa insulation kuita pasi pepamusoro-frequency uye yakakwirira-voltage yekushanda mamiriro.
Mechanical Strength uye Flexibility - Stress Concentration at Impurity Sites
Zvimedu zvetsvina yakaoma uye unplasticized resin agglomerates inoputsa kuenderera kwekupfeka. Pasi pekupeta uye kutambanudza uye kudzokororwa, kuputika kunonyanya kugadzira uye kupararira panzvimbo idzi dzisina simba, zvichikonzera kuderedzwa kwesimba rekusimba uye kupfupisa flex resistance yeupenyu.
2. Deteriorated coating adhesion
Yakawandisa yakasara ma surfactants inonetesa simba rekubatanidza pakati pePTFE nejira refiberglass, zvichikonzera kusakwana kwesimba re peel. Coatings akagadzirwa kubva kuhutsanana kwakanyatso kunyungudutswa PTFE anoratidza compact mameseji uye kuchinjika kunoshamisa, kugadzira jira rakaoma uye rinogara repamusoro-tembiricha.
Ruvara uye Chitarisiko - Yellowing Chiratidzo Chekuchena Yambiro
Yakachena PTFE yakasikwa mukaka chena uye semi-pachena. Yellow, iyo inonyanya kuzivikanwa pamusoro pejira rePTFE yepamusoro-tembiricha, inowanzobva mukusachena kwakanyanya mumidziyo:
Zvekugadzirisa chikafu, zvekurapa, uye zvemhando yepamusoro zvemagetsi zvikumbiro zvine hutsanana hutsanana, kuchena kwezvinhu zvinotaridza zvakananga kana zvigadzirwa zvakapedzwa zvichikwanisa kuita chitarisiko chakachena chakachena uye kusangana nekusasvibisa zvinodiwa.
Kemikari Kugadzikana uye Kuchengetedzeka Kwehutsanana - Njodzi Leaching
Yakachena PTFE inoramba corrosion kubva kunenge ese makemikari. Zvisinei, tsvina inonyunguduka mukati mejasi inogona kuparara kana ichiiswa kune yakasimba acids, yakasimba alkalis, kana organic solvents, zvichiita kuti kuvhara kuzvimba uye kupera.
Mukugadzira chikafu, kugadzira mishonga, uye semiconductor kunyorera, tsvaga tsvina inokuvadza (senge nhaka yePFOA yasara) muzvigadzirwa zvinotakura njodzi dzekutengesa zvinhu . Chete chepamusoro-chekucheneswa chikafu-giredhi uye zvekurapa-giredhi mbishi zvinhu zvinoteerana neFDA , EU, uye yakakodzera mitemo miitiro inovimbisa isiri-chepfu uye yakachengeteka kushandiswa.
Raw material kuchena inotonga yakananga mashanu epakati pekuita zviyero zvePTFE yakakwirira-tembiricha jira:

Aokai PTFE inoshandisa chete yakakwirira-kuchena PTFE emulsion uye yakanyatsocheneswa fiberglass substrates. Isu tinopa zvinyorwa zvakachena, zvinosanganisira FDA zvitupa zvekuteerera uye inorema simbi ongororo, pakukumbira.
Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana tsanangudzo dzakadzama, mamiriro ekushandiswa uye zvigadziriso zvakagadzirirwa zvechigadzirwa chedu chizere, kusanganisira PTFE high-temperature jira, PTFE high-temperature adhesive tepi, PTFE high-temperature mesh bhandi, seamless heat press bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira pazasi kuburikidza ne-fiber girasi, tapota taura nesu pazasi girasi resiresi, faibha inodzivirira, tapota taura nesu.
Kusimudzira hunyanzvi uye kutendeseka sehuzivi hwedu hwekutanga hwebhizinesi, isu tinopa nemoyo wese vatengi mhinduro dzemaindasitiri uye kufunga mushure mekutengesa sevhisi!
