Muchinjikwa-Chikamu Chimiro chePTFE Yakakwira-Tembiricha Mucheka: Pane Shanduko Layer Pakati pePTFE Coating uye Fiberglass Substrate?

Jiangsu Aokai New Materials, inyanzvi inogadzira machira ePTFE akakwira-tembiricha, anounza kwauri nzwisiso yakadzama. Seyepamusoro-inoshanda inoumbwa zvinhu, iyo microscopic cross-sectional chimiro chePTFE yakakwirira-tembiricha jira yakakosha pakudzivirirwa kwayo kwekushisa, kusvuura simba uye kuchinjika. Mukugadzira machira ePTFE akakwira-tembiricha, pane yakakosha  shanduko layer pakati pePTFE coating uye fiberglass substrate. Pasina iyi shanduko yeshanduko, yakasanganiswa yemaitiro kutendeseka kwePTFE yakakwirira-tembiricha jira haigone kuwanikwa.

Kuburikidza ne-cross-sectional microscopic ongororo, iyi shanduko yeshanduko haina kuumbwa nekemikari imwe chete, asi inzvimbo inoumbwa yemukati inovakwa kuburikidza neakawanda emuviri uye makemikari ekuchinja nzira. Magadzirirwo ekugadzira uye kuumbwa kweiyo shanduko layer inotsanangurwa sezvizvi:

1. Silane Coupling Agent Bonding Layer

Fiberglass isina kubatwa haigone kubatana zvakananga nePTFE resin. Naizvozvo, jira refiberglass rinofanirwa kugadziridzwa ne silane coupling agents mukugadzira. Imwe magumo eiyo coupling agent inopindirana nemapoka e silanol (Si-OH) pafiberglass pamusoro, nepo imwe magumo ine mapoka anoshanda ane hukama hwepamusoro kana reactivity kune fluororesins. Inoshanda sekemikari inosunga zambuko pakati pefiberglass skeleton uye PTFE coating, iyi dhizaini inopa yakakosha kemikari anchorage kune yakazara structural lamination.

2. Hot-Melt Adhesive Intermediate Layer

Mukuyambuka-chikamu chekutarisa kwepamusoro-giredhi PTFE yakakwirira-tembiricha jira, gradient transition layer ine PFA (Perfluoroalkoxy alkane) kana FEP (Fluorinated Ethylene Propylene) inogona kunyatsoonekwa pakati pePTFE coating uye fiberglass substrate. Munguva yekupisa-kupisa kwepamusoro, idzi fluoroplastics dzinonyunguduka dzinoita sezvinamira zvemukati zvinonyunguduka, zvinopinda nekuputira masumbu efiberglass kuita chikamu chinoenderera. Iyi yepakati layer inodzivirira kuvharika delamination pasi pekudzokorora kukotama uye kuchinjika mamiriro.

3. Mechanical Interlocking Interface

PTFE high-temperature jira inogadzirwa kuburikidza neakawanda impregnation uye maitiro ekuputira. Microscopically, PTFE emulsion inopinda mukati me micron-sized pores inogadzirwa ne warp uye weft weaving ye fiberglass machira. Mushure mekupisa nekurapa, iyo yakaomeswa PTFE resin inoumba matatu-dimensional mechanical anchoring chimiro nemucheka wefiber. Ichi chimiro chemukati chinopindirana chinopa yakavimbika mekiniki rutsigiro, ichivimbisa kugadzikana kwedimensional uye anti-delamination kuita mubasa renguva refu.

4. Gradient Buffer Interface

PTFE coating uye fiberglass inoratidzira akasiyana akasiyana coefficients ekuwedzera kwekupisa, izvo zvinokonzeresa kushushikana kwemukati mukati mekukurumidza kupisa uye kutonhora kutenderera. Mucheka wepamusoro wePTFE wepamusoro-tembiricha unotora chimiro che gradient chimiro: nzvimbo iri padyo nefiberglass yakapfuma mune zvinodzivirira kupisa uye FEP, ukuwo kuchena kwePTFE kunowedzera zvishoma nezvishoma kuenda kunze. Ichi chimiro che gradient chinodzivirira kushushikana kwekushisa pasi pemamiriro ekunze ekupisa uye inodzivirira kuputika kwepamusoro kwejasi.

5. Substrate Pretreatment Interface

Usati wagadzira machira ekuchinja ari pamusoro, jira refiberglass rinofanirwa kudzika-tembiricha dewaxing uye kuda kubvisa machira ekuisa saizi uye tsvina. Iyi yakakosha pretreatment nhanho inofumura inoshanda silanol mapoka pane fiber pamusoro, ichipa yakachena uye makemikari inoshanda interface kune inotevera yekubatanidza kurapwa uye resin kupinda.

Muchinjikwa-sectional chimiro chePTFE high-temperature jira inoumba yakazara composite sisitimu inoratidzirwa nechakasimba bonding, gradient kupinda uye pure resin inoshanda pamusoro . Kubatsirwa kubva kune akawanda-anoshanda eshanduko maseru akasanganiswa nekuvharika kwemuviri uye makemikari bonding, zvinyorwa zvinoramba zvakanakisa kuburitsa pfuma uye corrosion resistance yePTFE, nepo ichiwana yakatanhamara simba uye kuneta kuramba.

Izvo zviri pamusoro apa zvinopihwa neJiangsu Aokai New Material Technology Co., Ltd.

Tinopa huwandu hwakazara hwezvigadzirwa zvinosanganisira PTFE high-temperature jira, PTFE high-temperature tepi, PTFE high-temperature mesh belt, seamless fusing machine bhandi, single-sided PTFE coated fabric, high-temperature resistant conveyor bhandi uye high-temperature isingagadziriswi fiberglass jira. Kuti uwane yakadzama zvigadzirwa paramita, maapplication mhinduro uye akagadziridzwa masevhisi, ndapota taura nesu:
