Chithandizo Chapamwamba cha Polytetrafluoroethylene (PTFE)

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials adzayambitsa mankhwala apamwamba a polytetrafluoroethylene (PTFE).

PTFE imakhala yabwino kwambiri komanso yotsika kutentha kukana, kukana kwadzidzidzi kwamankhwala, kutsika kwamphamvu kwamphamvu komanso kudzipangira mafuta. Amagwiritsidwa ntchito kwambiri pamagetsi, makina, zipangizo zamakina, ndege, biomedicine ndi madera ena, kupeza mbiri ya 'King of Plastics' . Komabe, chifukwa cha inertness mankhwala ndi otsika pamwamba mphamvu, PTFE n'zovuta kugwirizana ndi zipangizo zina, amene malire ake ntchito kumlingo. Kuwongolera kumamatira pakati pa PTFE ndi zipangizo zosiyanasiyana, njira zambiri amatengedwa kuti kumapangitsanso pamwamba ntchito PTFE. Pazinthu zosiyanasiyana, Aokai New Materials nthawi zambiri imagwiritsa ntchito njira zosinthira za PTFE zotsatirazi.

1. Chithandizo cha Mankhwala Onyowa

The sodium-naphthalene mankhwala mankhwala  ndi imodzi mwa njira zothandiza PTFE pamwamba kusinthidwa. Ndi njira yosavuta komanso yotsika mtengo, ndiye chisankho chomwe chimakondedwa pakupanga kothandiza ku fakitale ya Aokai New Materials' PTFE.

Chithandizo cha sodium-naphthalene makamaka chimagwiritsa ntchito njira yolumikizira kuti igwirizane ndi mankhwala ndi PTFE, kuchotsa maatomu ena a fulorini pamwamba. Izi zimasiya gawo la carbonized ndikuyambitsa magulu a polar monga magulu a hydroxyl, magulu a carbonyl ndi maunsaturated bond. Magulu a polar awa amawonjezera mphamvu ya pamwamba pa polima, amachepetsa kukhudzana ndi ngodya ndikuwongolera kunyowa, motero amatembenuza PTFE kuchoka ku nonbondable kukhala wokhazikika.

2. Mechanochemical Bonding Njira

Pamene ma polima ndi pansi mphamvu kunja (mwachitsanzo, kuphwanya, akupera, mikangano, etc.), unyolo macromolecular kusweka ndi kukumana zimachitikira mankhwala, kuphatikizapo mechanodegradation, mechanochemical crosslinking, mechanochemical Ankalumikiza, chipika copolymerization ndi kupsyinjika adamulowetsa polymerization. Izi zimadziwika kuti polymer mechanochemical reactions.

Mu mgwirizano wa mechanochemical, zomatira-zokutidwa ndi polima pamwamba zimatikita. Kupyolera mu zochita za mechanochemical, polima pamwamba amadutsa mechanodegradation kupanga macromolecular free radicals, amene kenako kupanga covalent zomangira ndi zomatira mamolekyu, kupanga amphamvu kugwirizana mawonekedwe ndi bwino kwambiri kugwirizana mphamvu ya olowa.

3. Njira Yosungunuka Yotentha Kwambiri

Mfundo yaikulu yosinthira malo a PTFE pogwiritsa ntchito kutentha kwapamwamba kwambiri ndi: pa kutentha kwakukulu, crystalline morphology ya PTFE pamwamba imasinthidwa, ndi mphamvu zapamwamba, zomangika mosavuta monga SiO₂ ndi Al ufa zimayikidwa. Pambuyo kuzirala, wosanjikiza kusinthidwa munali zinthu bondable amapanga pa PTFE pamwamba. Popeza mamolekyu a zinthu zomangira alowa pamwamba maselo wosanjikiza wa PTFE, kuswa chomangira kumafuna intermolecular chiwonongeko, chifukwa mkulu kugwirizana mphamvu.

4. Njira Yopangira Ma radiation

PTFE imayikidwa mu zotakasika polymerizable monomers monga styrene, asidi fumaric, methacrylates ndi ena, ndiye irradiated ndi Co-60 . Izi zimayambitsa mankhwala kumezanitsa ma polymerization a monomers pa PTFE pamwamba, kupanga kumezanitsa polima wosanjikiza kuti n'zosavuta kugwirizana. Kumezanitsa kumasokonezanso pamwamba, kumawonjezera malo omangirira komanso kumawonjezera mphamvu zomangira.

5. Technology ya Plasma Treatment

Chithandizo cha plasma ndi imodzi mwamakina omwe akukula mwachangu pakusintha kwaposachedwa kwa PTFE m'zaka zaposachedwa.

Chofunikira chaukadaulo uwu ndikuyika zitsanzo mu chida chodzipatulira cha plasma, pomwe bombardation ya ayoni kapena implantation imathyola zomangira zama cell kapena kuyambitsa magulu ogwirira ntchito pamtunda wa polima, kuyambitsa pamwamba kuti akwaniritse kusintha. Ma Ioni amatha kukhala mpweya wa inert, mpweya wogwiritsa ntchito mankhwala kapena zinthu zachitsulo. Bombardment ndi mpweya wa inert amatha kusintha mawonekedwe a polima.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve zambiri, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse - kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, malamba opanda msoko amakina omangira, nsalu ya PTFE ya mbali imodzi, lamba wosamva kutentha kwapamwamba kwambiri, malamba osamva kutentha kwambiri ndi magalasi osamva zambiri ife:

·  Nambala yafoni yautumiki: Mr. Guo: +86 18944819998 Bambo Liu: +86 13705266308

Nthawi zonse timatsatira malingaliro autumiki otsika mtengo, ukatswiri ndi kukhulupirika, ndipo tadzipereka kukupatsirani mayankho oyimitsa kamodzi ndi ntchito yachidwi!
