Sei PTFE Yakakwira-Tembiricha Mucheka Ichipfeka Zvishoma Nezvishoma Pasi Inorema Froction Mamiriro?

Senyanzvi yekugadzira PTFE machira epamusoro-tembiricha, Jiangsu Aokai New Materials ichatsanangura kuti sei PTFE-yakavharwa girazi faibha jira richiratidza kusapfeka kwakaderedzwa pasi pezvinorema. Kupfeka kwayo kupikisa michina haikonzerwi nechinhu chimwe chete, asi inogona kunzwisiswa kubva kune zvinotevera zvinhu:

1. Yakanyanya Kuderera Kukurukurirana Coefficient uye Self-Lubricating Property

Polytetrafluoroethylene (PTFE) ine imwe yeakaderera friction coefficients pakati pezvinhu zvakasimba (dynamic friction coefficient approx. 0.04–0.10).

·  Molecular Structure : Kabhoni cheni yePTFE yakaputirwa zvakasimba nemaatomu efluorine ane yakakwirira uye yakafanana electron cloud cloud density, zvichikonzera kushaya simba kwakanyanya kwema intermolecular, kuumba 'molecular lubricating layer'.

·  Interfacial Slip : Panguva yekukweshana, PTFE mamorekuru cheni anorongedza zviri nyore munzira yekukwesha uye kugera pane counterface (semuenzaniso, simbi kana imwe nzvimbo yakaoma). Kupokana kunonyanya kuitika mukati mechinhu kana kutamisa firimu kwete kunama kwakananga uye kurima pane chinongedzo, kunoderedza zvakanyanya kukweshera uye kugera kushushikana uye kunonotsa chiyero chekupfeka.

2. Kutakura-Kutakura uye Kudzivisa Mhedzisiro yeGlass Fiber Fabric Core

PTFE high-temperature jira chinhu chinoumbwa chine girazi fiber jira se substrate uye PTFE seyokuputira.

·  Main Mutakuri Mutakuri : Girazi fiber jira rinopa yakakwira tensile simba uye dimensional kugadzikana. Pasi pekukweshana kunorema, girazi fiber inotakura yakawanda yakajairika mutoro uye shear simba, kudzivirira iyo PTFE kupfekedza kubva kubvaruka macroscopic kana kuyerera kwepurasitiki kunokonzerwa nekunyanya kushushikana.

·  Kurambidzwa kweWear Debris Formation : Iyo fiber framework inoganhura saizi yePTFE 'strip wear debris'. Yakachena PTFE inowanzoita marara akakura nekuda kwekuwanda kwema molecular chain kutambanudza, nepo girazi fiber network inokamura PTFE kuita madiki-region, ichivharira kupfeka kunzvimbo diki dzine zvidimbu zvakanaka. Kupfeka kunoratidzika se 'micro-abrasion' kwete 'macroscopic delamination', zvichidzikisa zvakanyanya mwero wekupfeka.

3. High Heat Resistance uye Thermal Stability

Heavy friction inoperekedzwa nefrictional heat generation. Zvakanakira zvePTFE high-temperature jira ndezvi:

Wide  -Temperature Stability : PTFE inochengetedza kushanda kwakadzikama kubva -200°C kusvika 260°C. Iko friction coefficient inoderera zvishoma nekukwira kwekushisa (mukati meimwe mutsara), kudzivisa kupfava, kunamatira kana kuora kwekushisa kunokonzerwa nekupisa kwepamusoro.

·  Heat Dissipation yeGlass Fiber : Girazi fiber ine yakanaka thermal conductivity, inobatsira kubvisa kupisa kwefrictional, kuderedza nzvimbo dzinopisa dzemunharaunda, uye kudzivirira kukanganisa kusati kwasvika kwePTFE nekuda kwekupisa kuunganidza.

4. Chemical Inertia uye Anti-Adhesion Property

PTFE inoshingirira kunenge kwese kemikari corrosion. Munzvimbo dzinokweshana dzine mafuta ekuzora, huruva kana zvinhu zvinoparadza, huso hwayo hahunyanyi kupfekwa nekemikari (semuenzaniso, oxidation kana corrosion-accelerated wear). Iyo yakaderera pamusoro pesimba inoita kuti zviome kune counter zvinhu kutonhora-weld kana kunamatira kune substrate, nekudaro kudzivirira kupfeka kwekunamatira.

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

Kune yakadzama paramita, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere, zvinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-tembiricha tepi, PTFE yakakwirira-tembiricha mesh bhandi, seamless laminating mabhandi, single-sided PTFE jira, yakakwirira-tembiricha isingachinjiki, faibha inodzivirira, machira anodzivirira, girazi rinodzivirira, girosi rinodzivirira, girazi rinopikisa
