Viscosity bakeng sa Adhesives le Sealants
Likhomaretsi li arotsoe ka li-adhesive tsa tlhaho le li-adhesives tsa maiketsetso ho ea ka tšimoloho ea tsona. Viscosity e nkuoa e le e hanyetsanang le mokelikeli kapa phallo. Likhomaretsi tsa viscous le li-sealants ke maro a seng a Newtonian. Ka mantsoe a mang, ho baloa ha viscosity ho itšetlehile ka sekhahla sa ho kuta se lekantsoeng.
Viscosity e phetha karolo ea bohlokoa tlhahisong le tšebelisong ea li-adhesives, e sebetsa e le pontšo ea bohlokoa ea thepa e kang density, botsitso, solvent content, sekhahla sa ho kopanya, boima ba limolek'hule, le ho lumellana ka kakaretso kapa kabo ea boholo ba likaroloana.
Viscosity ea likhomaretsi e fapana haholo ho latela ts'ebeliso ea tsona e reriloeng, joalo ka ho tiisa kapa ho kopanya. Likhomaretsi li arotsoe ka mefuta e tlase, e bohareng le e phahameng ea viscosity, e 'ngoe le e' ngoe e tšoanela linyeoe tse itseng tsa tšebeliso:
