Pehea e hana ai ka PTFE a me ke aniani Fiber Bond me ka ʻole o ka Delamination me ka ʻole o nā paʻa kemika?

ʻO Jiangsu Aokai New Materials, kahi mea hana nui o nā lole wela wela PTFE, wehewehe:

ʻAʻole hiki i ka Polytetrafluoroethylene (PTFE) a me ke aniani aniani (ka mea nui i haku ʻia me ka silica) ke hana i nā mea paʻa kemika. He haʻahaʻa loa ka ikehu ili o ka PTFE (ma kahi o 18 mN/m), i ʻike ʻia he 'non-stick coating', aʻo ke aniani fiber he mea ʻano hydrophilic polar inorganic. ʻAʻole kūpono nā mea ʻelua.

Ma Aokai, mākou impregnate aniani puluniu lole me ka PTFE emulsion, nui ma o ka penei: 'Oiai he paʻakikī o ka PTFE pono'ī, hiki ke hoʻohana 'ia ka mea hoʻohui (e like me ka silane) e kūkulu i ke alahaka ma ka ili aniani. ʻO ke kumumanaʻo: Ua uhi ʻia ka ʻili o ke aniani me kahi mea hoʻohui silane. Hoʻokahi hopena o ka silane (pūʻulu alkoxy) e hana i ka hopena condensation me nā hui silanol (Si-OH) ma ke aniani aniani e hana i nā mea paʻa kemika; ʻo ka hopena ʻē aʻe (e like me ka hui amino, pūʻulu epoxy) he reactive.

Inā ʻaʻole mālama ʻia ʻo PTFE ponoʻī, ʻaʻole hiki ke hoʻopaʻa ʻia ka hopena o ka mea hoʻohui me PTFE, no laila pono ke mālama ʻia. ʻO kahi hana maʻamau ka hoʻohui ʻana i nā mea hoʻohui a me nā mea hoʻopili polymer (e like me PFA, FEP - perfluoroalkoxy resin a i ʻole tetrafluoroethylene-hexafluoropropylene copolymer, he mau fluoroplastics hiki ke hoʻoheheʻe ʻia) i loko o ka emulsion PTFE.

Papa hoʻololi : Hoʻohana ʻia ka resin perfluoroalkoxy a i ʻole tetrafluoroethylene-hexafluoropropylene copolymer ma ke ʻano he papa waena. Loaʻa kēia mau fluoroplastics i ka hoʻohālikelike kemika maikaʻi me ka PTFE, hiki ke hoʻoheheʻe a kahe i kahi haʻahaʻa haʻahaʻa, e hoʻopaʻa i ka fiber glass silane me ka PTFE nui, e hana i kahi interface gradient, a hoʻopau i ka hoʻololi ʻana i ke kaumaha.

ʻO ka hoʻopaʻa ʻana ma waena o ka PTFE a me ka fiber aniani kahi hui kino o ka mechanical interlocking + stress compression + gradient transition layer..

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

No nā kikoʻī kikoʻī, nā hiʻohiʻona noiʻi a me nā hopena maʻamau o kā mākou huahana holoʻokoʻa - me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana tape, PTFE kiʻekiʻe wela mesh kāʻei, seamless kāʻei no ka mīkini hoʻopaʻa ʻana, ka lole PTFE hoʻokahi ʻaoʻao, kiʻekiʻe-weliweli kūpaʻa conveyor kāʻei, kiʻekiʻe-mehana pale aniani fiber lole a me nā huahana ʻē aʻe.

Ke kākoʻo nei mākou i kahi loiloi lawelawe ʻoihana a me ka ʻoiaʻiʻo, a ua hoʻolaʻa ʻia i ka hāʻawi ʻana iā ʻoe i nā hopena hoʻokahi a me ka lawelawe hoʻolohe!
