Mmetụta nke PTFE Emulsion pH Uru na nkwụsi ike ya na arụmọrụ impregnation.

Jiangsu Aokai New Materials, a PTFE elu-okpomọkụ ákwà emeputa, na-akọwa otú pH uru nke polytetrafluoroethylene (PTFE) emulsion na-eje ozi dị ka a oké egwu oke n'ịhụ na ya nhazi na ngwa arụmọrụ. Ngwaahịa ndị bụ isi na-edobe oke pH alkaline na-esighị ike nke 8.0-10.5 . Mgbanwe nke pH nwere ike ịkpalite mmeghachi omume yinye site na micro ruo ọkwa macro, na-emetụta nkwụsi ike nke sistemu (dịka, ndụ shelf, ikike mgbochi coagulation) na arụmọrụ impregnation (dịka ọmụmaatụ, permeability, ogo mkpuchi ikpeazụ).

1. Mmetụta na Stability

PTFE emulsion bụ a thermodynamically ejighị n'aka usoro nke nkwụsi ike tumadi na-adabere na electrostatic repulsion n'etiti PTFE microparticles. pH na-ahazi nguzozi isi a ozugbo.

Usoro nkwụsi ike Electrostatic (nwere ike nke Zeta)

Na mpaghara alkaline na-adịghị ike, microparticles PTFE na-ebu ebubo na-adịghị mma site na adsorbing hydroxyl ions (OH⁻), na ikike Zeta nke ihe dịka -50 mV ruo -65 mV . Nke a siri ike electrostatic repulsion zuru ezu iji merie ndị agha van der Waals ma na-eme ka ihe ndị ahụ gbasasịrị. Ọ bụrụ na pH na-adaba na ebe dịpụrụ adịpụ nke PTFE (gburugburu pH 2.9-3.2), ebubo elu na-ewepụ, ikike Zeta na-abịaru nso zero, na emulsion na-eme ngwa ngwa na-emebi ma na-enwe mgbagwoju anya na-apụghị ịgbagha agbagha.

Mmetụta nkwụsi ike nke gburugburu Alkaline

A na-edobe emulsions PTFE azụmaahịa na-adịghị ike alkaline tumadi maka ebumnuche ndị a:

· Mgbochi nke microbial ibu : A na-adịghị ike alkaline gburugburu ebe obibi na-egbochi nje bacteria, na-egbochi ha iri surfactants na destabilizing na emulsion.

· Mbelata nke mmebi acidic : Mpaghara alkaline na-ewepụ ihe ndị fọdụrụnụ acidic site na polymerization, na-ezere mmebi akụrụngwa na mmebi arụmọrụ.

Ihe ize ndụ nke mgbakwunye Acid

Mgbe ị na-edozi pH na acids dị ka acetic acid, a ghaghị ịgbakwunye acid ahụ nwayọọ nwayọọ na obere ntakịrị na mkpali dị nro na tupu dilution. Mgbakwunye ngwa ngwa ma ọ bụ oke acidity ga-akpaghasị nguzozi ụgwọ nke sistemu ahụ ma na-ebutekwa mmebi emulsion ozugbo.

2. Mmetụta na arụmọrụ impregnation

Impregnation na-achọ ka emulsion dị irè banye n'ime mkpụrụ ma mepụta mkpuchi edo. pH na-emetụta usoro a tumadi site n'ịgbanwe viscosity, wettability, na ụgwọ elu nke sistem.

Permeability na adhesion

pH na-emetụta omume rheological nke emulsion. PH kwesịrị ekwesị na-ebuli mgbasawanye na ntinye capillary n'elu ala ma na-ezere ntụpọ. Oke pH dị ala ma ọ bụ dị elu nwere ike ibelata nrapado mkpuchi.

Isi ihe njiri mara maka usoro mmekọ ọnụ

N'ime nkwadebe ihe mejupụtara, imezi pH na-enye ohere ijikwa ikike Zeta nke ụdị irighiri abụọ ma ọ bụ karịa, na-eme ka otu na coagulation dị mma site na mmekọrịta electrostatic. Dịka ọmụmaatụ, imezi pH nke carbon ojii na PTFE emulsion ngwakọta na 7-10  na-enweta coagulation zuru oke na-enweghị ihe mgbakwunye ọzọ.

Na Aokai New Materials, pH akara n'oge emulsion nkwadebe na mmepụta na-ekpuchi dum lifecycle nke PTFE emulsion si nchekwa na ikpeazụ ngwaahịa arụmọrụ, na-eme ka ọ dị oké mkpa n'ụzọ zuru ezu na-erigbu pụtara ìhè Njirimara nke PTFE ihe.

Ozi dị n'elu bụ Jiangsu Aokai New Materials Technology Co., Ltd.

Maka nkọwa zuru ezu, ihe ngosi ngwa na ngwọta ahaziri nke ngwaahịa anyị zuru oke gụnyere akwa PTFE dị elu, teepu PTFE dị elu, eriri akwa PTFE dị elu, eriri na-enweghị ihe ọ bụla maka igwe na-ejikọta ọnụ, akwa PTFE nwere otu akụkụ, akwa mkpuchi na-eguzogide okpomọkụ na elu-okpomọkụ: eriri glaze, biko kpọtụrụ anyị.
