Lintho tse tala tsa lebota la putty ke eng?

Wall putty ke thepa ea kaho e tsebahalang e sebelisoang meahong ea bolulo le ea khoebo. Ke lisebelisoa tse fapaneng tse sebelisetsoang ho boreleli le ho qeta mabota a ka hare le a ka ntle pele ho penta kapa wallpaper. Wall putty e entsoe ka lisebelisoa tse fapaneng tse tala tse kopantsoeng hammoho ho etsa ntho e teteaneng e kang peista. Sehloohong sena, re tla tšohla ka botlalo lisebelisoa tse tala tsa lebota la putty.

Samente e tšoeu:
Samente e tšoeu ke thepa ea mantlha e sebelisoang ho putty leboteng. Ke hydraulic binder e entsoeng ka klinka e tšoeu e fatše hamonate le gypsum. Samente e tšoeu e na le bosoeu bo phahameng le boemo bo tlaase ba tšepe le manganese oxide. E ratoa ka putty ea lebota kaha e fana ka pheletso e boreleli maboteng, e na le thepa e ntle ea ho khomarela, 'me e hanana le metsi.

Phofo ea 'mabole:
Phofo ea 'mabole ke sehlahisoa sa ho seha le ho belisoa ha 'mabole. E fatše hantle 'me e sebelisoa leboteng la putty ho matlafatsa matla le ho tšoarella ha eona. Marble powder ke diminerale ea tlhaho e nang le k'halsiamo e ngata 'me e na le thepa e ntle ea ho kopanya. E thusa ho fokotsa shrinkage ea putty le ho fana ka qetello e boreleli ho marako.

Talcum phofo:
Talcum powder ke diminerale e bonolo e sebelisoang leboteng la putty ho ntlafatsa ts'ebetso ea eona le ho fokotsa viscosity ea motsoako. E siiloe hantle 'me e na le bohloeki bo phahameng. Talcum phofo e thusa ho sebelisoa habonolo ha putty le ho ntlafatsa ho khomarela marako.

China letsopa:
Letsopa la China, le tsejoang hape e le kaolin, ke liminerale tsa tlhaho tse sebelisoang leboteng la putty joalo ka setlolo. E siiloe hantle 'me e na le bosoeu bo phahameng. China letsopa ke thepa e tala e theko e tlaase e sebelisetsoang ho ntlafatsa bongata ba putty le ho fokotsa litšenyehelo tsa eona.

Mica powder:
Mica powder ke diminerale ea tlhaho e sebelisoang leboteng la putty ho fana ka pheletso e benyang maboteng. E fatše hantle 'me e na le tekanyo e phahameng ea ho bonahatsa. Mica phofo e thusa ho fokotsa porosity ea putty mme e fana ka khanyetso e ntle ea metsi.

Lehlabathe la silika:
Lehlabathe la silika ke liminerale tsa tlhaho tse sebelisoang leboteng la putty joalo ka ho tlatsa. E siiloe hantle 'me e na le bohloeki bo phahameng. Lehlabathe la silika le thusa ho ntlafatsa matla a putty le ho fokotsa ho fokotseha ha eona. E boetse e thusa ho ntlafatsa ho khomarela ha putty marakong.

Metsi:
Metsi ke karolo ea bohlokoa ea putty ea lebota. E sebelisoa ho kopanya lintho tse tala hammoho le ho etsa ntho e kang peista. Metsi a thusa ho kenya tšebetsong thepa e tlamang ea samente mme a fana ka mokelikeli o hlokahalang ho motsoako.

Li-additives tsa lik'hemik'hale:
Li-additives tsa lik'hemik'hale li sebelisoa leboteng la putty ho ntlafatsa thepa le ts'ebetso ea eona. Lisebelisoa tsena li kenyelletsa li-retarder, li-accelerator, li-plasticizers le lintho tse thibelang metsi. Li-retarders li sebelisetsoa ho fokotsa nako ea ho beha putty, ha li-accelerator li sebelisetsoa ho potlakisa nako ea ho beha. Li-plasticizers li sebelisetsoa ho ntlafatsa ts'ebetso le ho fokotsa viscosity ea putty, ha lisebelisoa tsa ho thibela metsi li sebelisoa ho etsa hore putty e se ke ea thibela metsi.

Methyl celluloseke mofuta o tloaelehileng oa cellulose ether o sebelisoang leboteng putty. E entsoe ka phetoho ea lik'hemik'hale ea cellulose ea tlhaho e sebelisa methanol le alkali. Methyl cellulose ke phofo e tšoeu, e sa nkhang hamonate, 'me e sa latsoeheng e qhibilihang ka metsing 'me e etsa tharollo e hlakileng le e hlakileng. E na le thepa e ntle ea ho boloka metsi mme e ntlafatsa ts'ebetso ea putty. Methyl cellulose e boetse e fana ka sekhomaretsi se setle ho li-substrates tse fapaneng le ho ntlafatsa matla a thata a putty.

Hydroxyethyl cellulose ke mofuta o mong oa cellulose ether o sebelisoang leboteng putty. E entsoe ka phetoho ea lik'hemik'hale tsa cellulose ea tlhaho ho sebelisa ethylene oxide le alkali. Hydroxyethyl cellulose ke phofo e tšoeu, e sa nkhang hamonate, 'me e sa latsoeheng e qhibilihang metsing 'me e etsa tharollo e hlakileng le e hlakileng. E na le thepa e ntle ea ho boloka metsi mme e ntlafatsa ts'ebetso ea putty. Hydroxyethyl cellulose e boetse e fana ka mamarelo a matle ho li-substrates tse fapaneng le ho ntlafatsa matla a ho tiea a putty.

Carboxymethyl cellulose e boetse e sebelisoa leboteng putty joalo ka motenya le tlama. E entsoe ka phetoho ea lik'hemik'hale tsa cellulose ea tlhaho ho sebelisa monochloroacetic acid le alkali. Carboxymethyl cellulose ke phofo e tšoeu, e sa nkhang hamonate, 'me e sa latsoeheng e qhibilihang ka metsing 'me e etsa tharollo e hlakileng le e hlakileng. E na le thepa e ntle ea ho boloka metsi mme e ntlafatsa ts'ebetso ea putty. Carboxymethyl cellulose e boetse e fana ka sekhomaretsi se setle ho li-substrates tse fapaneng le ho ntlafatsa matla a thata a putty.

 

Qetellong, putty ea lebota e entsoe ka lisebelisoa tse fapaneng tse tala tse kopantsoeng hammoho ho etsa ntho e kang peista. Lisebelisoa tsa mantlha tse sebelisoang leboteng la putty ke samente e tšoeu, ha lisebelisoa tse ling li kenyelletsa phofo ea 'mabole, phofo ea talcum, letsopa la china, phofo ea mica, lehlabathe la silika, metsi le li-additives tsa lik'hemik'hale. Lisebelisoa tsena tse tala li khethiloe bakeng sa thepa ea tsona e khethehileng, e kang bosoeu, thepa ea ho kopanya, ho sebetsa le ho tšoarella, ho fana ka qetello e boreleli le e khanyang ho marako.
