HPMC ke eng bakeng sa putty leboteng?

Hydroxypropyl methylcellulose (HPMC)ke motsoako oa mantlha mekhoeng ea li-putty tsa lebota, e bapalang karolo ea bohlokoa ts'ebetsong ea eona le litšobotsing tsa ts'ebeliso. Motsoako ona o feto-fetohang o sebelisoa haholo thepa ea kaho ka lebaka la thepa ea eona e ikhethang. Mona ke kakaretso e felletseng ea HPMC bakeng sa putty ea lebota:

1. Sebopeho sa Lik'hemik'hale le Sebopeho:

HPMC ke semisynthetic, polymer e qhibilihang ka metsing e tsoang ho selulose.
Sebopeho sa eona se na le liketane tsa mokokotlo oa cellulose tse nang le hydroxypropyl le lihlopha tsa methyl tse khomaretsoeng.

2. Karolo ho Wall Putty:

HPMC e sebetsa e le tlatsetso ea bohlokoa mekhoeng ea li-putty tsa lebota, e tlatsetsang ho sebetsa ha eona, ho khomarela, le thepa ea ho boloka metsi.
E sebetsa e le ntho e matlafatsang, e matlafatsang botsitso ba putty le ho thibela ho theoha kapa ho rotha nakong ea kopo.

3. Paballo ea Metsi:

E 'ngoe ea mesebetsi ea mantlha ea HPMC ke ho boloka metsi ka har'a motsoako oa putty.
Thepa ena e etsa bonnete ba hore hydration ea nako e telele ea likaroloana tsa samente, e khothalletsa pholiso e ntle le ho ntlafatsa maqhama ho substrate.

4. Ts'ebetso e Ntlafetseng:

HPMCe fana ka bokhoni bo botle ba ho sebetsa leboteng la putty, ho etsa hore ho be bonolo ho e sebelisa le ho hasana ka ho lekana libakeng tse fapaneng.
E ntlafatsa boreleli le botsitso ba putty, e lumellang kopo e seamless le ho phethela.

5. Ntlafatso ea ho khomarela:

HPMC e khothalletsa ho khomarela ka matla pakeng tsa putty ea lebota le substrate, ebang ke konkreite, samente, kapa masonry.
Ka ho etsa filimi e kopanetsoeng holim'a metsi, e ntlafatsa matla a ho kopanya le ho tšoarella ha putty layer.

6. Crack Resistance:

Wall putty e nang le HPMC e bonts'a khanyetso e matlafalitsoeng ea crack, kaha e thusa ho fokotsa shrinkage nakong ea ho omisa.
Ka ho fokotsa ho thehoa ha mapetsong le mapheo, e tlatsetsa ho phela nako e telele le boipiletso bo botle ba sebaka se pentiloeng.

7. Ho lumellana le Li-additives:

HPMC e sebelisana le li-additives tse fapaneng tse sebelisoang hangata ho li-putty formulations, joalo ka li-dispersants, defoamers, le li-preservatives.
Khokahano ena e lumella ho feto-fetoha ha maemo ha ho etsoa li-putty tse lumellanang le litlhoko tse itseng tsa ts'ebetso.

8. Maikutlo a Tikoloho le Bophelo bo Botle:

HPMC e nkuoa e le botsoalle ho tikoloho ebile e bolokehile hore e ka sebelisoa thepa ea kaho.
Ha e chefo, ha e tenehe ebile ha e na chefo, e baka kotsi e fokolang ho bophelo ba batho kapa tikolohong.

9. Litaelo tsa Tšebeliso:

Tekanyetso ea HPMC ka har'a mabota a putty formulations hangata e tloha ho 0.1% ho isa ho 0.5% ka boima ba samente.
Phatlalatso e nepahetseng le ho kopanya ho bohlokoa ho netefatsa kabo e ts'oanang ea HPMC ho pholletsa le motsoako oa putty.

10. Tiisetso ea Boleng:

Baetsi ba marako putty hangata ba khomarela litekanyetso tsa boleng le litlhaloso ho netefatsa katleho le botsitso ba lihlahisoa tsa bona.
HPMC e sebelisoang mefuteng ea putty ea lebota e lokela ho kopana le maemo a bohlokoa a indasteri le ho etsa liteko tse matla bakeng sa ts'ebetso le netefatso ea boleng.

Hydroxypropyl methylcellulose (HPMC)ke tlatsetso ea bohlokoahali mekhoeng ea li-putty tsa lebota, e fanang ka melemo e mengata e kenyelletsang ts'ebetso e ntlafetseng, ho khomarela, ho boloka metsi, le ho hanyetsa crack. Ho feto-fetoha ha eona le ho tsamaellana le lisebelisoa tse ling ho etsa hore e be khetho e ratoang bakeng sa ho ntlafatsa ts'ebetso le ho tšoarella ha li-putty tsa lebota lits'ebetsong tsa kaho.
