Ebikosa PTFE Emulsion pH Value ku Stability yaayo n’enkola y’okufukirira

Jiangsu Aokai New Materials, kkampuni ekola olugoye olw’ebbugumu eringi mu PTFE, annyonnyola engeri omuwendo gwa pH ogwa polytetrafluoroethylene (PTFE) emulsion gye gukola nga parameter enkulu okukakasa nti gukola bulungi n’okugukozesa. Ebintu ebikulu bitera okukuuma pH enywevu enafu eya alkaline eya 8.0–10.5 . Enkyukakyuka mu pH esobola okuleetawo enkola y’olujegere okuva ku mitendera gya micro okutuuka ku macro, okukosa okutebenkera kw’enkola (okugeza, obulamu bw’okutereka, obusobozi bw’okuziyiza okuzimba) n’omulimu gw’okufukirira (okugeza, okuyita, omutindo gw’okusiiga ogusembayo).

1. Ebikosa Okutebenkera

PTFE emulsion nkola ya thermodynamically etali nnywevu ng’obutebenkevu bwayo okusinga bwesigamye ku electrostatic repulsion wakati wa PTFE microparticles. pH etereeza butereevu bbalansi eno enkulu.

Enkola y’okutebenkeza amasannyalaze (Zeta Potential) .

Mu mbeera ya alkaline enafu, obutundutundu bwa PTFE bufuuka obuzito obubi nga bunyiga ayoni za hydroxyl (OH−), nga zirina obusobozi bwa Zeta nga -50 mV okutuuka ku -65 mV . Okugoba kuno okw’amaanyi okw’amasannyalaze kumala okuvvuunuka empalirizo za van der Waals n’okukuuma obutundutundu nga busaasaanidde.Singa pH ekka okutuuka ku kifo kya isoelectric point ya PTFE (okwetooloola pH 2.9–3.2), ebisannyalazo eby’okungulu bifuuka ebitali bimu, Zeta potential esemberera ziro, era emulsion etabangula mangu era n’eyita mu coagulation etakyukakyuka.

Okutebenkeza Effect y’obutonde bwa Alkaline

Emulsions za PTFE ez’ettunzi zikuumibwa nga tezirina alkaline enafu okusinga olw’ensonga zino wammanga:

· Okuziyiza okukula kw’obuwuka obutonotono : Embeera enafu ya alkaline enyigiriza okukula kwa bakitiriya, okuziremesa okulya ebirungo ebikola ku ttaka n’okutabangula emulsion.

· Okunyigiriza okuvunda kwa asidi : Embeera ya alkaline efuula ebintu bya asidi ebisigaddewo okuva mu polimeeri, okwewala okukulukuta kw’ebyuma n’okuvunda kw’omulimu.

Obulabe bw’okugattako asidi

Bw’oba ​​otereeza pH ne asidi nga asidi aseeti, asidi alina okugattibwako mpola mu bungi obutono ng’osika mpola n’okusooka okufukibwa. Okwongera amangu oba asidi asusse kijja kutaataaganya bbalansi ya chajingi y’enkola era era kireetewo okumenya amangu emulsion.

2. Ebikosa Enkola y’okufukirira

Okufukirira kyetaagisa emulsion okuyingira obulungi mu substrate n’okukola ekizigo ekimu. pH ekwata ku nkola eno okusinga ng’ekyusa obuzito, obunnyogovu, n’obuzito bw’okungulu kw’ensengekera.

Okuyita mu mazzi n’okunywerera

pH ekosa enneeyisa ya rheological ya emulsion. pH entuufu eyamba okusaasaana n’okuyingira kw’emisuwa ku ngulu wa substrate era yeewala obulema. pH entono oba waggulu ennyo eyinza okukendeeza ku kwekwata kw’ekizigo.

Key Parameter for Enkola ya Co-Coagulation

Mu kutegeka ebintu ebigatta, okutereeza pH kisobozesa okufuga obusobozi bwa Zeta obw’ebika by’obutundutundu bibiri oba okusingawo, okusobozesa okugatta awamu era okulungi okuyita mu nkolagana y’amasannyalaze. Okugeza, okutereeza pH y’omutabula gwa kaboni omuddugavu ne PTFE emulsion okutuuka ku 7–10  kituuka ku kuzimba okujjuvu awatali kuzimba kwongera.

Ku Aokai New Materials, okufuga pH mu kiseera kyonna eky’okuteekateeka n’okufulumya emulsion kukwata ku bulamu bwonna obw’emulsion ya PTFE okuva ku kutereka okutuuka ku kukola kw’ebintu ebisembayo, ekifuula ekyetaagisa okukozesa mu bujjuvu eby’obugagga eby’enjawulo eby’ebintu bya PTFE.

Amawulire ago waggulu gaweereddwa kkampuni ya Jiangsu Aokai New Materials Technology Co., Ltd.

Ku parameters enzijuvu, enkola z’okukozesa n’okugonjoola ebigonjoola eby’ebintu byaffe ebijjuvu omuli PTFE olugoye olw’ebbugumu eringi, PTFE olugoye olw’ebbugumu eringi, PTFE omusipi ogw’ebbugumu eringi, emisipi egitalina musonno egy’ebyuma ebisiba, olugoye lwa PTFE olw’oludda olumu, emisipi egy’okutambuza egy’ebbugumu eringi n’olugoye lwa fiberglass olw’ebbugumu eringi, tukusaba otuukirire ku:
