Mathata a tloaelehileng ka ho fetisisa a kaho ea poso ea phofo ea ka hare ea lerako ke ho phunya le ho soeufala. Ho utloisisa mabaka a ho peeling ea phofo e ka hare ea lebota la putty, ho hlokahala hore u qale ho utloisisa motsoako oa motheo oa lihlahisoa tse tala le molao-motheo oa ho folisa oa phofo ea ka hare ea lerako. Ebe, ho ipapisitse le ho omella, ho monya metsi, mocheso le ho omella ha lerako nakong ea kaho ea putty, tseba hore na mabaka a ka sehloohong a ho peeling ka har'a lerako la putty phofo le ho sebelisa mekhoa e lumellanang ho rarolla bothata ba putty powder peeling.

一、 Sebopeho sa motheo sa lihlahisoa tse entsoeng ka hare ho lerako la putty powder:

Likarolo tsa motheo tsa ka hare ho lebota putty phofo kenyeletsa: inorganic bonding lintho tse bonahalang (grey calcium), fillers (boima k'halsiamo phofo, talcum phofo, joalo-joalo), le polymer additives (HPMC, polyvinyl joala, rabara phofo, joalo-joalo). Har'a tsona, phofo e ka hare ea lebota la putty hangata ha e kenye samente e tšoeu kapa e eketsa samente e nyane e tšoeu feela. Redispersible latex powder ha e na phello e fokolang ka tekanyo e tlase, kahoo ha e sebelisoe haholo ka hare ho lebota la putty powder ka lebaka la mathata a litšenyehelo kapa ha e sebelisoe ka seoelo.

Kahoo ka lebaka la bothata ka mokhoa oa ka hare oa lerako putty powder ka boeona:

1. Lisebelisoa tsa ho kopanya lintho tse sa tloaelehang, tse kang tlatsetso e tlaase ea k'halsiamo e bohlooho le boleng bo sa tsitsang ba k'halsiamo e bohlooho;

2. Ho eketsoa ha likarolo tsa ho kopanya li-additives tsa polymer tse tlaase haholo kapa tse sa finyelle litekanyetso tsa boleng ho ka etsa hore lerako le ka hare la putty le oe.

二、 Mochini oa ho folisa oa phofo ea putty ea ka hare:

Pheko ea ka hare ea lebota la putty powder haholo-holo e itšetlehile ka phello ea synergistic ea phofo ea lime calcium, HPMC le li-additives tse ling tsa polymer tlas'a maemo a ho kolobisa ho tiisa, ho etsa filimi, le ho tsitsisa mokhoa oa ho folisa.

Molao-motheo o thata oa phofo ea grey calcium:

Ho omisa le ho thatafatsa: Nakong ea ts'ebetso ea ho senya, metsi a mangata a fetoha mouoane ho tloha phofshoana e bohlooho ea calcium, ho etsa marang-rang a maholo a li-pores tse tšoanang ka har'a slurry. Metsi a sa lefelloeng a setseng ka har'a li-pores, ka lebaka la tsitsipano ea holim'a metsi, a hlahisa khatello ea capillary, e leng ho etsang hore likaroloana tsa phofshoana tse bohlooho tsa calcium li kopane haholoanyane, kahoo li fumana matla. Ha slurry e omisitsoe le ho feta, phello ena e boetse e matlafatsoa. Ho thatafala ha Crystallization: Likaroloana tsa colloidal tse hasantsoeng haholo ka har'a slurry li arohanngoa ke lera la phallo lipakeng tsa likaroloana. Ha metsi a ntse a fokotseha butle-butle, sekhahla sa phallo se fokotseha butle-butle, 'me ka hona likaroloana tsa colloidal li khomarelana tlas'a ketso ea matla a limolek'hule, ho etsa marang-rang a sebaka sa mehaho e khutsitseng, kahoo e fumana matla. Ho thatafala ha carbon: The slurry e monya khase ea CO2 moeeng, e etsa calcium carbonate eo ha e le hantle e sa qhibiliheng metsing. Mokhoa ona o bitsoa carbonation ea slurry. Likarabo tsa kopanelo ke tse latelang:

Ca(OH)2+CO2+H2O→CaCO3+(n+1)H2O

Likristale tse entsoeng ka calcium carbonate li kopane hammoho kapa li na le likaroloana tsa calcium hydroxide, li etsa marang-rang a thata a kristale, kahoo a ntlafatsa matla a slurry. Ho feta moo, ka lebaka la molumo o tiileng o ntseng o eketseha oa calcium carbonate ha o bapisoa le calcium hydroxide, slurry ea phofo ea grey e thata e batla e tiile haholoanyane. 3, Ka mor'a hore putty phofo e sebelisoe leboteng, metsi a putty a lahleheloa haholo ka litsela tse tharo:

Moea oa metsi holim'a putty ha k'halsiamo e bohlooho le samente e tšoeu li itšoara ka har'a phofo e monyang ea bokaholimo ba lebota. 3. Tšusumetso ea mabaka a kaho ho tšollo ea phofo ea putty powder:

Mabaka a tahlehelo ea phofo e bakoang ke kaho e kenyelletsa: maemo a fokolang a tlhokomelo a etsang hore putty e ome ka potlako le ho se be le matla a lekaneng; Sebaka sa motheo sa lerako se omme haholo, se etsa hore putty e lahleheloe ke metsi ka potlako; Botenya bo feteletseng ba putty ka batch e le 'ngoe.
