Kamoo Li-additives tsa Seretse se Itokisitseng li Ntlafatsa Tlhahlobo ea Ts'ebetso ea Seretse

01. Motsoako oa seretse o itokiselitseng

The anionic surfactant e fumanehang ka har'a motsoako oa seretse o itokiselitseng morero o ka etsa hore likaroloana tsa samente li qhalane, li lokolle metsi a sa lefelloeng a koahetsoeng ke samente aggregate, li arole ka ho feletseng boima ba samente e kopantsoeng, 'me li e noe metsi ka ho feletseng ho finyella mohaho o kopanetsoeng. eketsa bongata ba seretse.Matla, ho ntlafatsa ho se khonehe, ho hanyetsa lepetso le ho tšoarella.Seretse se kopantsoeng le li-additives tsa seretse se itokiselitseng se na le ts'ebetso e ntle ea ho sebetsa, tekanyo e phahameng ea ho boloka metsi, matla a matla a momahaneng, a se nang chefo, a se nang kotsi, a bolokehile ebile a se na tikoloho nakong ea ts'ebetso.E loketse bakeng sa tlhahiso ea masonry a tloaelehileng, ho liloa, fatše, le seretse se sa keneleng metsi lifekthering tsa seretse tse seng li lokisitsoe.E sebelisetsoa ho haha ​​le ho haha ​​litene tsa letsopa tsa konkreite, litene tsa ceramsite, litene tse sekoti, litene tsa konkreite, litene tse sa chesoang mehahong e fapaneng ea indasteri le ea sechaba.Kaho ea ho lila lebota ka hare le kantle, ho polastera leboteng la konkreite, ho beakanya fatše le marulelo, seretse se sa keneleng metsi, joalo-joalo.

02. Cellulose ether

Ka seretse se seng se kopantsoe, cellulose ether ke motsoako o ka sehloohong o ka ntlafatsang haholo ts'ebetso ea seretse se metsi le ho ama ts'ebetso ea kaho ea seretse.Khetho e utloahalang ea li-cellulose ethers tsa mefuta e sa tšoaneng, li-viscosities tse fapaneng, boholo bo fapaneng ba likaroloana, likhato tse fapaneng tsa viscosity le chelete e eketsehileng e tla ba le phello e ntle ntlafatsong ea ts'ebetso ea seretse se omeletseng sa phofo.

Tlhahiso ea cellulose ether e entsoe haholo ka likhoele tsa tlhaho ka ho qhibiliha ha alkali, karabelo ea grafting (etherification), ho hlatsoa, ​​​​ho omisa, ho qoelisoa le lits'ebetso tse ling.Ha ho etsoa thepa ea ho haha, haholo-holo phofo e omeletseng ea seretse, cellulose ether e phetha karolo e ke keng ea nkeloa sebaka, haholo-holo tlhahiso ea seretse se khethehileng (seretse se fetotsoeng), ke karolo ea bohlokoa le ea bohlokoa.Cellulose ether e bapala karolo ea ho boloka metsi, ho teteaneng, ho liehisa matla a hydration a samente, le ho ntlafatsa ts'ebetso ea kaho.Bokhoni bo botle ba ho boloka metsi bo etsa hore hydration ea samente e phethehe haholoanyane, e ka ntlafatsa viscosity e metsi ea seretse se metsi, ea eketsa matla a tlamahano ea seretse, le ho lokisa nako.Ho kenyelletsa cellulose ether ho seretse sa ho fafatsa ka mochini ho ka ntlafatsa ts'ebetso ea ho fafatsa kapa ho pompa le matla a sebopeho sa seretse.Ka hona, ether ea cellulose e sebelisoa haholo e le tlatsetso ea bohlokoa ka har'a seretse se seng se kopantsoe.Li-cellulose ethers tse sebelisoang seretseng se seng se tsoakoa haholo-holo ke methyl hydroxyethyl cellulose ether le methyl hydroxypropyl cellulose ether., ba nka karolo e fetang 90% ea karolo ea 'maraka.

03. Redispersible latex phofo

Redispersible latex powder ke phofo ea thermoplastic resin e fumanoang ka ho omisa ka spray le ts'ebetso e latelang ea emulsion ea polymer.E sebelisoa haholo-holo kahong, haholo-holo seretse sa phofo se omeletseng ho eketsa momahano, momahano le ho fetoha habonolo.

Karolo ea phofo ea latex e ka sebelisoang hape ka seretse: phofo ea latex e ka sebelisoang hape e etsa filimi ka mor'a ho hasana 'me e sebetsa e le sekhomaretsi sa bobeli ho matlafatsa ho khomarela;colloid e sireletsang e kenngoa ke tsamaiso ea seretse 'me e ke ke ea senngoa ke metsi ka mor'a ho thehoa ha filimi Kapa li-dispersions tse peli;resin ea polymer e entsoeng ka filimi e ajoa ho pholletsa le tsamaiso ea seretse e le thepa e matlafatsang, kahoo e eketsa ho kopana ha seretse.

Redispersible latex phofo ka seretse se metsi e ka ntlafatsa ts'ebetso ea kaho, ho ntlafatsa ts'ebetso ea phallo, ho eketsa thixotropy le sag resistance, ho ntlafatsa momahano, ho lelefatsa nako e bulehileng, ho matlafatsa ho boloka metsi, joalo-joalo Ka mor'a hore seretse se phekoloe, se ka ntlafatsa matla a ho tsitsa.Matla a tsitsitseng, matla a matla a ho khumama, ho fokotsa modulus ea elastic, ho holofala ho ntlafetseng, ho eketsa ho kopana ha thepa, ho ntlafatsa ho hanyetsa ho apara, ho matlafatsa matla a ho kopanya, ho fokotsa botebo ba carbonization, ho fokotsa ho monya ha metsi, le ho etsa hore thepa e be le mokhoa o babatsehang oa ho leleka metsi ka metsi le tse ling. liphello.

04. Moemeli oa ho kenya moea

Air-entraining agent, eo hape e tsejoang e le air-entraining agent, e bolela ho kenngoa ha palo e kholo ea li-micro-bubble tse ngata tse arolelanoang ka mokhoa o ts'oanang nakong ea ho kopanya seretse, tse ka fokotsang tsitsipano ea holim'a metsi ka seretse, e leng se bakang ho hasana ho molemo. le ho fokotsa motsoako oa seretse.Ho tsoa mali, ho arola li-additives.Ho phaella moo, ho kenngoa ha li-bubble tsa moea tse ntle le tse tsitsitseng ho boetse ho ntlafatsa ts'ebetso ea kaho.Palo ea moea e hlahisoang e itšetlehile ka mofuta oa seretse le lisebelisoa tsa ho kopanya tse sebelisoang.

Le hoja palo ea moemeli ea kenang moeeng e le nyenyane haholo, moemeli oa ho kenya moea o na le tšusumetso e kholo mosebetsing oa seretse se lokiselitsoeng, se ka ntlafatsang ka katleho ho sebetsa ha seretse se lokiselitsoeng, ho ntlafatsa ho se tsitse le ho hanyetsa serame sa seretse. , le ho fokotsa boima ba seretse , boloka thepa le ho eketsa sebaka sa kaho, empa ho eketsoa ha moemeli oa ho kenya moea ho tla fokotsa matla a seretse, haholo-holo seretse se hatellang.Correlation intensity ho fumana hore na tekanyo e nepahetseng ke efe.

05. Moemeli oa matla oa pele

Moemeli oa matla oa pele ke tlatsetso e ka potlakisang nts'etsopele ea matla a pele a seretse, tseo boholo ba tsona e leng li-electrolyte tsa inorganic, 'me tse seng kae ke metsoako ea manyolo.

The accelerator bakeng sa seretse se seng se lokiselitsoe ho hlokahala hore e be phofo le ho omella.Calcium formate ke eona e sebelisoang haholo seretseng se seng se tsoakoa.Calcium formate e ka ntlafatsa matla a pele a seretse, 'me ea potlakisa hydration ea tricalcium silicate, e ka fokotsang metsi ho isa tekanyong e itseng.Ho feta moo, thepa ea 'mele ea calcium formate e tsitsitse mocheso oa kamore.Ha ho bonolo ho agglomerate mme e loketse ho sebelisoa ka seretse se omileng sa phofo.

06. Metsi a fokotsang metsi

Moemeli oa ho fokotsa metsi o bua ka tlatsetso e ka fokotsang palo ea ho kopanya metsi tlas'a boemo ba ho boloka ho lumellana ha seretse ho tšoana hantle.Sehlahisoa sa metsi ka kakaretso ke sehlahisoa sa metsi, se ka aroloa ka lisebelisoa tse tloaelehileng tse fokotsang metsi, tse fokotsang metsi tse sebetsang hantle haholo, tse fokotsang matla a pele a metsi, tse fokotsang metsi a sa sebetseng hantle, tse fokotsang matla a phahameng a metsi le tse fokotsang metsi a kenang moeeng ho latela mesebetsi ea tsona.Mefuta-futa.

Sehlahisoa sa metsi se sebelisetsoang ho etsa seretse se seng se tsoakoa se hlokoa hore e be phofo le ho omella.Mochine o joalo oa ho fokotsa metsi o ka qhalakanngoa ka ho lekana ka har'a seretse se omeletseng sa phofo ntle le ho fokotsa nako ea bophelo ba sethala sa seretse se seng se kopantsoe.Hajoale, ts'ebeliso ea seretse se fokotsang metsi ka seretse se kopantsoeng ka kakaretso ke samente ea boithaopo, boithapollo ba gypsum, seretse sa plastering, seretse se sa keneleng metsi, putty, joalo-joalo. thepa ea seretse.Khetha.
