Nā hopena o ka PTFE Emulsion pH waiwai ma kona kūpaʻa a me ka hana impregnation

ʻO Jiangsu Aokai New Materials, he PTFE kiʻekiʻe-mehana lole mea hana, wehewehe pehea ka pH waiwai o polytetrafluoroethylene (PTFE) emulsion lawelawe ma ke ano he koʻikoʻi hoʻohālikelike e hōʻoiaʻiʻo ana i ka hana a me ka noi hana. Hoʻomau mau nā huahana koʻikoʻi i kahi pae pH paʻa nāwaliwali o 8.0-10.5 . Hiki i ka loli o ka pH ke hoʻoulu i ke kaulahao mai ka micro a hiki i ka pae macro, e pili ana i ka paʻa o ka ʻōnaehana (e laʻa, ke ola o ka pale, ka mana anti-coagulation) a me ka hana impregnation (eg, permeability, ka maikaʻi o ka uhi hope).

1. Nā hopena i ke kūpaʻa

ʻO ka emulsion PTFE kahi ʻōnaehana thermodynamically unstable nona ka hilinaʻi nui ma luna o ka repulsion electrostatic ma waena o nā microparticles PTFE. Hoʻoponopono pololei ka pH i kēia kaulike kī.

Mechanism Ho'opa'a Electrostatic (Zeta Potential)

I loko o kahi kaiapuni alkaline nāwaliwali, ua hoʻopiʻi maikaʻi ʻia nā microparticles PTFE e ka adsorbing hydroxyl ions (OH⁻), me kahi hiki Zeta ma kahi o -50 mV a -65 mV . Ua lawa kēia hoʻokuke electrostatic ikaika e lanakila ai i nā pūʻali van der Waals a mālama i nā mea i hoʻopuehu ʻia.

Hoʻopaʻa i ka hopena o ke kaiapuni alkaline

Mālama ʻia nā emulsions PTFE pāʻoihana me ka nāwaliwali alkaline no nā kumu penei:

· Kaohi ʻana i ka ulu ʻana o ka microbial : ʻO kahi wahi alkaline nāwaliwali e hoʻopau i ka ulu ʻana o ka bacteria, e pale ana iā lākou mai ka ʻai ʻana i nā surfactants a me ka hoʻohaumia ʻana i ka emulsion.

· Hoʻopau i ka hoʻohaʻahaʻa ʻana i ka waikawa : Hoʻopau ke kaiapuni alkaline i ke koena o nā mea ʻakika mai ka polymerization, e pale ana i ka ʻino o nā mea hana a me ka hōʻino ʻana i ka hana.

Nā pilikia o ka hoʻohui ʻana i ka ʻakika

I ka hoʻoponopono ʻana i ka pH me nā ʻakika e like me ka acetic acid, pono e hoʻohui mālie ʻia ka waika ma nā liʻiliʻi liʻiliʻi me ka hoʻoulu ʻana a me ka pre-dilution. ʻO ka hoʻohui wikiwiki ʻana a i ʻole ka nui o ka waikawa e hoʻopau i ke koena o ka uku o ka ʻōnaehana a hoʻomaka koke i ka haki ʻana i ka emulsion.

2. Nā hopena i ka hana impregnation

Pono ka Impregnation i ka emulsion e komo pono i ka substrate a hana i kahi uhi ʻaʻahu. Hoʻopili ka pH i kēia kaʻina hana ma ka hoʻololi ʻana i ka viscosity, wettability, a me ka hoʻouka ʻana o ka ʻili o ka ʻōnaehana.

Permeability a Hoʻopili

Pili ka pH i ka hana rheological o ka emulsion. Hoʻonui ka pH kūpono i ka laha ʻana a me ke komo ʻana o ka capillary ma ka ʻili o ka substrate a pale i nā hemahema. Hiki i ka pH haʻahaʻa haʻahaʻa a kiʻekiʻe paha ke hōʻemi i ka pili ʻana o ka uhi.

ʻO ka ʻāpana koʻikoʻi no ke kaʻina hana coagulation

I ka hoʻomākaukau ʻana i nā mea hana, hiki i ka hoʻoponopono ʻana i ka pH ke hoʻomalu i ka mana Zeta o ʻelua a ʻoi aku paha nā ʻano o nā ʻāpana, e hiki ai i ka hui like a me ka maikaʻi o ka coagulation ma o ka pilina electrostatic. No ka laʻana, hoʻololi i ka pH o kahi huila kalapona ʻeleʻele a me PTFE emulsion i ka 7-10  e loaʻa ai ka coagulation piha me ka ʻole o nā coagulants.

Ma Aokai New Materials, pH mana i loko o ka emulsion hoomakaukau a me ka hana e uhi i ka holoʻokoʻa lifecycle o PTFE emulsion mai ka waiho ana a hiki i ka hopena huahana hana, e pono ai e hoʻohana pono i nā waiwai koʻikoʻi o nā mea PTFE.
