Ayyuka na masu kauri a cikin PTFE Emulsion - Matsayin Maɓalli 4

A cikin samar da PTFE high-zazzabi masana'anta , da impregnation mataki yana amfani da PTFE emulsion (mai ruwa watsawa). Amma raw PTFE emulsion kadai yana da wuyar aiwatarwa yadda ya kamata. Ana kara masu kauri don gyara halayen rheological da kwanciyar hankali.

Me yasa? PTFE guduro yana da babban yawa kuma yana son daidaitawa. Ba tare da masu kauri ba, emulsion zai rabu, ya shiga cikin masana'anta sosai, ko kuma ya samar da sutura marasa daidaituwa.

Aokai PTFE ya inganta zaɓin thickener a cikin nau'o'in impregnation da yawa. Wannan labarin ya bayyana hudu core ayyuka na thickeners a PTFE emulsion.

Dakatar Dakatarwar & Anti-Settling

PTFE guduro yana da babban yawa (kimanin 2.2 g/cm ⊃3;) kuma yana ƙoƙarin daidaitawa da taurare sosai a cikin ruwa. Ba tare da kwanciyar hankali ba, emulsion ya rabu zuwa wani yanki mai wadataccen ruwa da ruwa mai tsabta - yana sa ba za a iya amfani da shi don daidaitaccen sutura ba.

Yadda masu kauri ke aiki: Masu kauri suna ɗaga ɗankowar yanayin ruwan ruwa, suna kafa tsarin hanyar sadarwa wanda ke tallafawa barbashi na guduro. Wannan:

• Yana haɓaka rayuwar rayuwar emulsion - ya kasance mai amfani na tsawon watanni maimakon kwanaki

• Yana hana rabuwar lokaci yayin sufuri da ajiya

• Yana kawar da caking - laka mai tauri a kasan kwantena

Aokai PTFE bayanin kula: Domin emulsions adana a kan 30 days, muna bada shawarar sake homogenization kafin amfani, ko da tare da thickeners, kamar yadda dogon lokaci a tsaye ajiya iya sa jinkirin daidaitawa.

Shear-Thinning Behavior for Easy Processing

Thickeners suna ba da emulsion tare da halayen ƙarfi mai ƙarfi (pseudoplastic): babban danko a hutawa, ƙarancin danko a ƙarƙashin tashin hankali..

Tasiri mai amfani: A lokacin suturar tsoma, emulsion yana gudana cikin yardar kaina a cikin masana'anta na fiberglass a ƙarƙashin ƙarfi, sannan yayi kauri nan da nan bayan shafi don kula da kauri mai rigar fim ɗin ba tare da drips ba.

A lokacin da impregnating porous substrates kamar fiberglass zane, daidaita nau'in da sashi na thickeners damar daidai iko a kan emulsion zurfin shigar azzakari cikin farji..

Yadda masu kauri ke sarrafa wannan: Maɗaukakin danko yana jinkirta shiga, yana barin ƙarin guduro a saman. Ƙananan danko yana ba da damar zurfafa shiga cikin gungun fiberglass. Wannan yana ƙayyade ƙimar guduro ta ƙarshe da jin daɗin samfuran da aka gama.

Haɓaka Daidaitawar Fina-Finai & Tabbatar da Rago-Yancin Sintering

1. Daidaiton fim a lokacin bushewa

Isasshen danko daga thickeners:

• Yana hana tsagewar da ke haifar da saurin ƙaurawar danshi yayin bushewa

• Yana hana kauri mara daidaituwa (kaurin gefuna, tsakiyar bakin ciki)

• Yana sauƙaƙa samar da lebur, fina-finai na farko na ci gaba

• Yana rage tasirin zoben kofi' inda emulsion ke ƙaura zuwa gefuna

2. Muhimmin abin da ake buƙata - rago-free sintering

PTFE emulsion yana buƙatar sintering a kusan 380 ° C don haɗa ƙwayoyin PTFE a cikin fim mai ci gaba. Wannan yana gabatar da buƙatu na musamman don thickeners:

Zaɓaɓɓen masu kauri dole ne su ƙone gaba ɗaya ba tare da ragowar toka ba a wannan zafin.

Aokai PTFE yana amfani da kauri na tushen cellulose (misali, methyl cellulose) wanda ke ƙonewa gaba ɗaya a 380 ° C, ba tare da toka ba. Muna ba da shawarar guje wa kauri masu ɗauke da gishirin inorganic ko oxides na ƙarfe waɗanda ke barin ragowar.

Takaitawa - Ma'aunin Zaɓin Thickener don Emulsion na PTFE

Aokai PTFE yana zaɓar masu kauri waɗanda ke daidaita duk ayyuka huɗu yayin tabbatar da cikakken konewa yayin sintering. Domin al'ada impregnation formulations, za mu iya daidaita thickener irin da sashi don daidaita your takamaiman shafi nauyi da masana'anta shigar bukatun.
