Karolo ea phofo ea latex e ka sebelisoang hape ke efe ho itšebetsa ka gypsum?

Redispersible latex powder ke tlatsetso ea bohlokoa e amang ts'ebetso ea seretse se ikemetseng sa gypsum-based self-leveling. Tšusumetso ea phofshoana ea latex e qhalakantsoeng hape holim'a thepa ea 'mele le ea mechine ea seretse se teteaneng sa gypsum-based self-leveling se lekoa,' me phofo ea latex e redispersible e senoloa ka tlhahlobo ea microscopic. Molao-motheo oa ho ntlafatsa thepa ea mochini oa seretse sa gypsum-based self-leveling e bontša hore redispersible latex powder e bapala karolo e kholo ho itšebetseng ka gypsum.

Redispersible latex powder ke setlamo sa manyolo se sebelisoang haholo, se ka ntlafatsang ts'ebetso ea lihlahisoa ha se sebelisoa thepa ea moaho e thehiloeng ho gypsum. Liteko li fumane hore metsi a qalang a gypsum-based self-leveling seretse a eketseha pele ebe a fokotseha ka ho eketseha ha phofo ea latex. Lebaka ke hore phofo ea latex e na le viscosity e itseng metsing a qhibilihisitsoeng. Bokhoni ba ho emisa ha slurry ho filler bo ntlafatsoa, ​​e leng molemo ho phallo ea slurry; ha palo ea phofo ea latex e ntse e eketseha, ho eketseha ha viscosity ea slurry ho lebisa ho eketseha ha viscosity ea slurry, 'me ho phalla ho bontša mokhoa o theohelang. Palo ea phofo ea latex e batla e se na phello ho 20min fluidity ea seretse.

Joalo ka setlamo sa manyolo, matla a phofo ea latex a itšetlehile ka ho tsoa ha metsi ka har'a slurry, 'me matla a tlamahano a thehoa ke ho thehoa ha filimi. Boemong bo omeletseng, metsi a seretse sa gypsum-based self-leveling a fetoha mouoane, 'me phofo ea latex e ka etsa filimi e tsoelang pele. Ho khomarela ho molemo, matla a omileng a gypsum-based self-leveling seretse se eketseha ka ho eketseha ha palo ea phofo ea latex.

Ka har'a seretse se ikemetseng sa gypsum ntle le phofo ea latex, ho na le palo e kholo ea likristale tsa gypsum tse bōpehileng joaloka molamu le li-columnar dihydrate le likristale tse sa tloaelehang tsa li-filler dihydrate gypsum le pakeng tsa likristale tsa gypsum tsa dihydrate le li-filler. Bokella hammoho ho etsa seretse se ikemetseng se thehiloeng ho gypsum se hlahise matla, 'me seretse se ikemetseng se thehiloeng ho gypsum se kopantsoeng le phofshoana ea morao-rao ea latex, phofo ea latex e theha khokahanyo ea likhoele ka har'a seretse se ikemetseng sa gypsum, le dihydrate. gypsum crystals le fillers, crystals Borokho ba tlhaho bo thehoa pakeng tsa kristale le dihydrate gypsum crystal, 'me filimi ea tlhaho e thehoa holim'a kristale ea gypsum ea dihydrate ho koahela le ho hokahanya likarolo tse pota-potileng pakeng tsa likristale tsa gypsum tsa dihydrate, kahoo li eketsa momahano le momahano. ea gypsum-based self-leveling seretse le ho ntlafatsa matla a gypsum-based self-leveling seretse phofo ea latex e na le thepa ea ho etsa filimi ka har'a seretse, e ka ntlafatsang ho kopana le ho kopanya matla a seretse se omileng. Ho thehoa ha maqhama a sebetsang pakeng tsa li-fillers ho ntlafatsa momahano pakeng tsa likristale tsa gypsum tsa dihydrate le li-fillers, ka hona ho ntlafatsa matla a tlamahano ea seretse se ikemetseng sa gypsum macroscopically.
