Mesebetsi ea Thickeners ho PTFE Emulsion - Likarolo tse 4 tsa Bohlokoa

Tlhahisong ea PTFE lesela la mocheso o phahameng oa mocheso , mohato oa ho kenya letsoho o sebelisa emulsion ea PTFE (aqueous dispersion). Empa emulsion e tala ea PTFE feela e thata ho sebetsa ka katleho. Li-thickeners li eketsoa ho fetola boitšoaro ba eona ba rheological le botsitso.

Hobaneng? Resin ea PTFE e na le letsoalo le phahameng 'me e tloaetse ho tsitsa. Ntle le li-thickeners, emulsion e ne e tla arohana, e kene ka botebo ka har'a lesela, kapa e hlahise liaparo tse sa tšoaneng.

Aokai PTFE e ntlafalitse khetho ea 'thickener' ho mefuta e mengata ea ho inregnation. Sengoliloeng sena se hlalosa mesebetsi e mene ea mantlha ea li-thickeners ho PTFE emulsion.

Suspension Stabilization & Anti-Settling

PTFE resin e na le segokanyipalo se phahameng (hoo e ka bang 2.2 g/cm³) 'me e rata ho lula le ho thatafala haholo metsing. Ntle le ho tsitsisa, emulsion e arohana ka sekhahla se nang le sediment le lera le hlakileng la mokelikeli - ho etsa hore e se ke ea sebelisoa bakeng sa ho roala ka mokhoa o tsitsitseng.

Li-thickeners li sebetsa joang: Li-thickeners li phahamisa haholo viscosity ea karolo ea metsi, ho etsa mohaho oa marang-rang o tšehetsang likaroloana tsa resin. Sena:

• E eketsa bophelo ba sethala sa emulsion - e lula e sebelisoa likhoeli ho fapana le matsatsi

• E thibela karohano ea mekhahlelo nakong ea lipalangoang le polokelo

• E felisa caking - sediment e thata ka tlase ho lijana

Tlhokomeliso ea Aokai PTFE: Bakeng sa li-emulsions tse bolokiloeng ka matsatsi a 30, re khothaletsa ho boela homogenization pele o sebelisoa, esita le ka li-thickeners, kaha polokelo ea nako e telele e ntse e ka baka ho tsitsisa butle.

Shear-Thinning Behaviour for Easy Processing

Li-thickeners li fa emulsion ka boits'oaro ba shear-thinning (pseudoplastic): viscosity e phahameng ha u phomotse, viscosity e tlase tlasa pherekano..

Tšusumetso e sebetsang: Nakong ea ho roala, emulsion e phalla ka bolokolohi ka har'a lesela la fiberglass tlas'a ho kuta, ebe e teteaneng hang ka mor'a ho roala ho boloka botenya ba filimi e metsi ntle le marotholi.

Ho Laola Botebo ba ho Kena le Boima ba ho Koaela

Ha o kenya li-substrates tse porous joalo ka lesela la fiberglass, ho lokisa mofuta le litekanyetso tsa li-thickeners ho lumella taolo e nepahetseng holim'a botebo ba ho kenella ha emulsion..

Kamoo li-thickeners li laolang sena kateng: Viscosity e phahameng e liehisa ho kenella, e siea resin e ngata holim'a metsi. Viscosity e tlase e lumella ho kenella ka botebo ka har'a bongata ba fiberglass. Sena se etsa qeto ea ho kenya resin ea ho qetela le maikutlo a matsoho a lihlahisoa tse felileng.

Ho Ntlafatsa Motsoako oa Lifilimi le ho Etsa bonnete ba hore ha ho na Masala a Sintering

1. Ho tšoana ha filimi nakong ea ho omisa

Viscosity e lekaneng ho tloha ho li-thickeners:

• E hatella ho phatloha ho bakoang ke ho falla ha mongobo ka potlako nakong ea ho omisa

• E thibela botenya bo sa lekaneng ba ho roala (mathōko a teteaneng, setsi se tšesaane)

• E thusa ho theha lifilimi tsa mantlha tse bataletseng, tse tsoelang pele

• E fokotsa ''coffee ring effect' moo emulsion e fetelang mathōkong

2. Tlhokahalo ea bohlokoa - sintering ntle le masala

PTFE emulsion hloka sintering hoo e ka bang 380°C ho fuse PTFE likaroloana ho ba filimi e tsoelang pele. Sena se fana ka tlhokahalo e ikhethang bakeng sa li-thickeners:

Li-thickeners tse khethiloeng li tlameha ho chesa ka ho feletseng ntle le molora o setseng mocheso ona.

Aokai PTFE e sebelisa li-thickeners tse thehiloeng ho cellulose (mohlala, methyl cellulose) tse tukang ka botlalo ho 380°C, li sa siee molora. Re khothaletsa ho qoba li-thickeners tse nang le letsoai le inorganic kapa metal oxides tse sieang masalla.

Kakaretso - Thickener Selection Criteria for PTFE Emulsion

Aokai PTFE e khetha li-thickeners tse leka-lekaneng mesebetsi eohle e mene ha li ntse li netefatsa hore li tuka ka ho feletseng nakong ea sintering. Bakeng sa litlhophiso tsa tloaelo tsa ho kenya, re ka fetola mofuta oa thickener le litekanyetso ho lumellana le boima ba hau ba ho roala le litlhoko tsa ho kenella ha lesela.

Kakaretso ena ea tekheniki e fanoa ke Jiangsu Aokai New Material Technology Co., Ltd.

Haeba o hloka lintlha tse qaqileng, linyeoe tsa kopo le litharollo tse hlophisitsoeng bakeng sa lihlahisoa tsa rona tse feletseng tse kenyelletsang masela a mocheso o phahameng oa PTFE, litheipi tse khomarelang tsa PTFE, mabanta a marang-rang a PTFE, mabanta a mochine o motlakase, lesela le nang le mahlakoreng a le mong a PTFE, mabanta a conveyor a sa keneleng mocheso le mocheso o phahameng ka tlaase ho fiberglass ka masela.
