Nkɛntɛnso a Storage Tebea horow nya wɔ PTFE Emulsion no Stability ne Impregnation Adwumayɛ so

Jiangsu Aokai New Materials – a ɔyɛ PTFE ntama a ɛyɛ hyew kɛse – kyerɛkyerɛ sɛnea PTFE emulsion a wɔkora so tebea ne ne dwumadi a wɔde di dwuma awiei no wɔ abusuabɔ kɛse. Ɔhyew a wɔhwɛ so, ambient humidity, ne shelf-life maintenance bere a wɔde sie no kyerɛ tẽẽ sɛnea PTFE emulsion no gyina pintinn, a ɛno nso nya film-forming uniformity ne dwumadi so nkɛntɛnso wɔ PTFE emulsion impregnation nhyehyɛe no mu. Sɛ wɔkora so yiye a, ebetumi ama honam fam nsakrae a wontumi nsakra aba PTFE emulsion mu, na ama wontumi mfa nni dwuma mfa nyɛ.

1. Nkɛntɛnso a Ɔhyew nya wɔ PTFE Emulsion so

Ɔhyew ne honam fam ade a ɛho hia sen biara a ɛka PTFE emulsion a ɛyɛ mmerɛw kɛse wɔ ɔhyew mu nsakrae ho no gyinabea.

Adeyɛ : Ɛsɛ sɛ wɔde PTFE emulsion sie denneennen wɔ baabi a ɛhɔ yɛ hyew bere nyinaa a ɛyɛ 5°C kosi 25°C . Saa kwan yi hwɛ hu sɛ resin asinasin a ɛwɔ PTFE emulsion mu no kɔ so sɛn na ɛpete.

Asiane a ɛwɔ ɔhyew a ɛba fam mu : Sɛ ɔhyew a atwa yɛn ho ahyia no kɔ fam sen 0°C a, nsu a ɛwɔ PTFE emulsion no mu no bɛyɛ nwini. Nsukyenee ahwehwɛ bɛpaapae micelle ahobammɔ fã a ɛwɔ emulsion no mu, na ama resin asinasin no ayɛ agglomeration a wontumi nsakra. Sɛ ɔhyew no kɔ soro akyiri yi mpo a, PTFE emulsion no ntumi nsan nnya ne mfitiase tebea no bio; ɛbɛyɛ nsu a ɛte sɛ curd na ayɛ nea enni mu koraa.

Asiane a ɛwɔ ɔhyew a ɛkɔ soro mu : Sɛ obi de ne ho to ɔhyew a ɛboro 35°C mu bere tenten a, ɛtew nneɛma a ɛma nneɛma yɛ adwuma wɔ PTFE emulsion mu no dwumadi so, ɛma Brownian motion collisions yɛ kɛse, na ɛsan nso kanyan demulsification ne sedimentation a ɛwɔ emulsion no mu.

2. Nkɛntɛnso a Humidity ne Sealing nya wɔ PTFE Emulsion so

Mframa a ɛmma PTFE emulsion a wɔde kyekyere nneɛma mu no nya ne nkwa nna so nkɛntɛnso tẽẽ.

Nneɛma a atwa yɛn ho ahyia ho ahwehwɛde : Ɛsɛ sɛ wɔde PTFE emulsion sie wɔ adekoradan a ɛhɔ yɛ kusuu, ɛhɔ yɛ nwini, na mframa pa fa mu.

3. Nkɛntɛnso a Shelf Life ne Sedimentation nya wɔ PTFE Emulsion so

PTFE emulsion nyɛ nsu a ɛyɛ den daa na ɛbɛtena hɔ bere a wogyina hɔ no.

Nkwa nna a wɔde di dwuma : PTFE emulsion a wɔanbue no taa nya asram 6 kosi 12 . Sɛ ɛte sɛ nea emulsion a ne bere atwam no yɛ nea ɛfata mpo a, ne impregnation adhesion ne film-forming su ahorow no bɛsɛe kɛse.

Daa agitation : Esiane sɛ resin asinasin a ɛwɔ PTFE emulsion mu no wɔ density a ɛkorɔn sen nsu nti, abɔde mu stratification ba wɔ gravity ase. Sɛnea ɛbɛyɛ na wɔahwɛ ahu sɛ ɛyɛ pɛ no, ɛho hia sɛ wosiesie emulsion a wɔde asie no daa.
