PTFE Molecular Structure uye Yayo Yakanakisa Zvivakwa

Senyanzvi sosi inogadzira machira ePTFE akakwira-tembiricha, Jiangsu Aokai New Materials inounza iwe ruzivo rwehunyanzvi. Iyo yakakosha chikamu chePTFE high-temperature jira iPolytetrafluoroethylene (PTFE), ine molecular chimiro che (mathbf{-(CF_2-CF_2)_n-}). Iyo carbon main chain yakaputirwa zvachose nemaatomu efluorine. Aya matatu epamusoro zvivakwa zvinoenderana nemaitiro ePTFE mamorekuru pamatanho akasiyana:

1. Yakanakisa Non-stick Property

Inotorwa kubva kune yakanyanya-yakaderera pasi pesimba, inotemerwa nekuputira kwekunze kweatomu yefluorine  uye molecular non-polarity..

·  Yakakwirira kudzivirira maitiro efluorine maatomu: Fluorine ine yakasimba kwazvo yemagetsi uye yakakura van der Waals radius. Inogara yakarongedzerwa mudenderedzwa padivi rekunze reketani yekabhoni, maatomu efluorine anoumba goko rinodzivirira rakasimba uye rinogadzira nzvimbo ine fluorinated yakazara yakatsetseka.

Simba  risina simba repakati pemamolekyulu: Kunyangwe iyo CF bond iri polar yakasimba, iyo yakazara symmetrical kurongeka inoita kuti iyo yese molecular cheni isiri polar. Masimba ekupararira asina simba chete aripo pakati pemamorekuru, zvichiita kuti pave nesimba rakaderera zvikuru repamusoro (approx. 18 mN/m). Zvinenge pasina zvinhu zvinogona kupararira kana kunamatira kune PTFE pamusoro.

2. Yakasimba Acid & Alkali Corrosion Resistance

Yakatorwa kubva kune yakanyanyisa makemikari bond inertness, inotemerwa nepamusoro CF bond simba  uye steric shielding effect..

·  High-simba CF bond: Iyo CF bond ine Ultra-yakakwirira bond simba (approx. 485 kJ/mol), yakatsiga kupfuura CH neCC bond, uye yakanyanya kuoma kutyoka.

·  Dziviriro yakakwana yekudzivirira: Iyo gobvu yakakora yefluorine atomu inoputira zvizere kabhoni cheni skeleton, kudzivirira maion anoparadza kubva pakusangana nekemikari iri panjodzi yekabhoni. Iyo inoona mbiri mbiri uye makemikari inert kudzivirira.

3. Superior Electrical Insulation

Yakatorwa kubva kune yakanyanya kuderera polarizability uye zero yemahara machaji, akatemerwa nemolecular symmetry  uye yakasimba maelectron binding effect..

·  Integral non-polar structure: Zvisinei nenharaunda yeCF bond, kurongeka kwakakwana kwemaatomu efluorine kumativi ose eketani yekabhoni kunoguma neine zero yakazara mamolecular dipole nguva, zvichiita kuti PTFE ive yakajairika isiri-polar zvinhu.

·  Maerekitironi akasungwa zvakasimba: Kusimba kwemagetsi kweatomu efluorine kunokweva makore erekitironi akananga kumaatomu efluorine. Maerekitironi mukati memamorekuru haakwanise kutama kana kuzorora pasi pemunda wemagetsi wekunze, nekushaikwa kwekutakura machaji ekutakura. Naizvozvo, PTFE inozvirumbidza ekupedzisira-yakaderera dielectric kurasikirwa uye yakanyanya kuparara simba.

Summary

Kuputirwa kwakazara kwemacheni ekabhoni nemaatomu efluorine, mapfupi ane simba guru reCF covalent bond, uye anonyatso symmetrical asiri-polar molecular marongero akabatana anobatsira mukuita kwakasiyana kwePTFE: kusanamira, kusadzivirirwa kwecorrosion uye kupisa kwemagetsi kwakanyanya.

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

Kana iwe uchida ruzivo rwakadzama nezve yakadzama paramita, mamiriro ekushandisa uye yakagadziridzwa mhinduro kune yedu yakazara chigadzirwa renji, kusanganisira PTFE yakakwirira-tembiricha machira, PTFE high-temperature matepi, PTFE high-temperature mesh mabhandi, seamless fuser mabhandi, single-sided PTFE yakavharidzirwa machira, high-temperature resistant fiber, high-temperature machira, ndapota inzwa wakasununguka kutibata nesu:

·  Nharembozha yebasa: Mr. Guo: +86 18944819998

·  Mr. Liu: +86 13705266308

Isu tinogara tichinamatira kune sevhisi dzidziso yehunyanzvi uye kutendeseka, uye nemoyo wese tinokupa iwe-yekumira mhinduro uye ine kufunga mushure mekutengesa sevhisi.
