Kurapa Kwepamusoro kwePolytetrafluoroethylene (PTFE)

Senyanzvi inogadzira machira ePTFE akakwira-tembiricha machira, Jiangsu Aokai New Materials ichasuma kurapwa kwepamusoro kwe polytetrafluoroethylene (PTFE).

PTFE inoratidzira yakakwira uye yakaderera tembiricha kuramba, yakasarudzika kemikari corrosion resistance, yakaderera friction coefficient uye self-lubricating zvivakwa. Inoshandiswa zvakanyanya mumagetsi, michina, makemikari emidziyo, aerospace, biomedicine nemamwe minda, inowana mukurumbira we 'Mambo wePlastiki' . Nekudaro, nekuda kwekemikari inertness uye yakaderera pamusoro pesimba, PTFE yakaoma kusungirirana nezvimwe zvinhu, izvo zvinoganhurira maapplication ayo kune imwe nhanho. Kuti uvandudze kunamatira pakati pePTFE uye zvakasiyana-siyana zvinhu, nzira dzinowanzo gamuchirwa kusimudzira basa repamusoro rePTFE. Kune zvigadzirwa zvakasiyana, Aokai New Materials inowanzo shandisa nzira dzinotevera dzePTFE pamusoro pekugadzirisa.

1. Wet Chemical Treatment

Iyo sodium-naphthalene kemikari kurapwa  ndiyo imwe yenzira dzinoshanda dzePTFE pamusoro pekugadzirisa. Nemaitiro akareruka uye mutengo wakaderera, ndiyo sarudzo inosarudzika mukugadzirwa kunoshanda kuAokai New Materials 'PTFE fekitori.

Sodium-naphthalene kurapwa kunonyanya kushandisa etching mhinduro kugadzirisa kemikari nePTFE, kubvisa mamwe maatomu efluorine kubva pamusoro. Izvi zvinosiya carbonized layer uye zvinounza mapoka epolar senge hydroxyl mapoka, carbonyl mapoka uye unsaturated bonds. Aya mapoka epolar anowedzera simba repamusoro pepolymer, kuderedza kuonana kwekona uye kunatsiridza kunyorova, nokudaro kushandura PTFE kubva kusingabatike kuita bondable.

2. Mechanochemical Bonding Method

Kana mapolymers akaiswa pasi pemasimba ekunze (semuenzaniso, kupwanya, kugaya, friction, nezvimwewo), macromolecular cheni dzinopwanya uye dzinoita kemikari maitiro, kusanganisira mechanodegradation, mechanochemical crosslinking, mechanochemical grafting, block copolymerization uye kusagadzikana-activated polymerization. Aya anozivikanwa sepolymer mechanochemical reactions.

Mune mechanochemical bonding, iyo inonamira-yakavharwa polymer pamusoro inokwizwa. Kuburikidza ne mechanochemical action, iyo polymer surface inopinda mechanodegradation kuti igadzire macromolecular free radicals, iyo inobva yaumba covalent zvisungo nemamolekemu anonamatira, zvichiita kuti pave nekubatana kwakasimba uye kunatsiridza zvikuru simba rekubatanidza rejoini.

3. High-Temperature Melting Method

Nheyo inokosha yekushandura nzvimbo dzePTFE kuburikidza nekunyunguduka kwepamusoro-soro ndeyokuti: pakupisa kwepamusoro, crystalline morphology yePTFE pamusoro inoshandurwa, uye yakakwirira-pamusoro-simba, zvinhu zvinosungirirwa zviri nyore zvakadai seSiO₂ neAl powder zvakabatanidzwa. Mushure mekutonhodza, dhizaini yakagadziridzwa ine zvinhu zvinosungirirwa inoumba pamusoro pePTFE. Sezvo mamorekuru ezvinhu zvinosungirirwa akapinda mukati mepamusoro molecular layer yePTFE, kutyora chisungo kunoda kuparadzwa kwe intermolecular, zvichikonzera kusimba kwepamusoro.

4. Radiation Method

PTFE inoiswa mune reactive polymerizable monomers senge styrene, fumaric acid, methacrylates nemamwe, yobva yaiswa irradied neCo -60 . Izvi zvinokonzeresa kemikari graft polymerization yemamonomers pamusoro pePTFE pamusoro, ichigadzira graft polymer layer iri nyore kusunga. Grafting zvakare inoshatisa pamusoro, inowedzera nzvimbo yekubatanidza uye inowedzera simba rekubatanidza.

5. Plasma Treatment Technology

Kurapwa kwePlasma ndeimwe yeakanyanya kukurumidza kusimukira matekinoroji ePTFE pamusoro pekugadzirisa mumakore achangopfuura.

Chakakosha cheiyi tekinoroji ndechekuisa sample mune yakatsaurirwa plasma yekurapa mudziyo, uko ion bombardment kana kuisirwa inopwanya mamolecular bond kana kusuma mapoka anoshanda pane iyo polymer pamusoro, ichimisikidza pamusoro kuti iwane shanduko. Ioni inogona kuva inert magasi, makemikari anoshanda magasi kana esimbi zvinhu. Bombardment ine inert magasi inogona kushandura chimiro chepamusoro chepolymer.

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

Kuti uwane ruzivo rwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziriswa zvechigadzirwa chedu chizere - zvinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-tembiricha mesh bhandi, mabhandi asina musono emichina yekubatanidza, jira rimwechete-sided PTFE, yakakwirira-tembiricha isingachinjiki girazi - ndapota tarisa-inodzivirira girazi remahara isu:
