Ho ntlafatsa Putty le Gypsum Performance Ho Sebelisa MHEC

Ntlafatso ea putty le gypsum phofo ka ho kenyelletsa methylhydroxyethylcellulose (MHEC). MHEC ke polymer e entsoeng ka selulose e sebelisoang haholo ho thepa ea kaho ka lebaka la ho boloka metsi, ho teteaneng le thepa ea rheological. Phuputso ena e ile ea batlisisa phello ea MHEC ho litšobotsi tsa bohlokoa tsa ts'ebetso ea putty le stucco, ho kenyelletsa le ho sebetsa, ho khomarela le ho beha nako. Liphuputso li thusa ho ntlafatsa boleng ba kakaretso le ho fumaneha ha thepa ena ea bohlokoa ea mohaho.

tsebisa:

1.1 Tšimoloho:

Putty le stucco ke likarolo tsa bohlokoa mohahong, ho fana ka libaka tse boreleli, ho koahela ho se phethahale, le ho ntlafatsa botle ba mohaho. Thepa ea lisebelisoa tsena, joalo ka ts'ebetso le ho khomarela, e bohlokoa molemong oa ts'ebeliso ea bona e atlehileng. Methylhydroxyethylcellulose (MHEC) e hohetse tlhokomelo bakeng sa bokhoni ba eona ba ho ntlafatsa ts'ebetso ea thepa ea mohaho.

1.2 Maikemisetso:

Sepheo se seholo e ne e le ho ithuta phello ea MHEC ho thepa ea putty le gypsum powder. Lipheo tse ikhethileng li kenyelletsa ho lekola ts'ebetso, matla a bond, le ho beha nako ea ho ntlafatsa tlhahiso ea lisebelisoa tsena.

kakaretso ea lingoliloeng:

2.1 MHEC ka thepa ea kaho:

Liphuputso tse fetileng li totobalitse ho feto-fetoha ha maemo a MHEC ho ntlafatsa ts'ebetso ea mefuta e sa tšoaneng ea thepa ea kaho, ho kenyelletsa le liretse tse entsoeng ka samente le lihlahisoa tse entsoeng ka gypsum. Tlhahlobo ea lingoliloeng e hlahloba mekhoa eo MHEC e amang ho sebetsa ka eona, ho boloka metsi le ho khomarela.

2.2 Recipe ea li-putty le samente:

Ho utloisisa metsoako le litlhoko tsa putty le gypsum powder ho bohlokoa ho etsa motsoako o sebetsang. Karolo ena e shebana le lipehelo tsa moetlo le ho supa libaka tse lokelang ho ntlafatsoa ts'ebetsong le ts'ebetsong.

mokhoa:

3.1 Khetho ea lintho tse bonahalang:

Khetho e hlokolosi ea lisebelisoa tse tala, ho kenyelletsa putty le gypsum powder hammoho le MHEC, ke ea bohlokoa ho finyella liphello tse lakatsehang. Phuputso e hlalosa lintlha tsa thepa e sebelisoang le mabaka a ka sehloohong a khetho ea bona.

3.2 Moralo oa liteko:

Lenaneo le hlophisitsoeng la liteko le ile la hlahisoa ho sekaseka phello ea maikutlo a fapaneng a MHEC holim'a thepa ea putty le stucco. Lintlha tsa bohlokoa tse kang ho sebetsa, matla a bond le nako ea ho seta li lekantsoe ka mekhoa e tloaelehileng ea tlhahlobo.

Liphetho le puisano:

4.1 Theha:

Tšusumetso ea MHEC mabapi le ho sebetsa ha putty le stucco e hlahlojoa ka liteko tse kang tlhahlobo ea benche ea phallo le tlhahlobo ea ho putlama. Liphetho li ile tsa hlahlojoa ho fumana hore na mahloriso a MHEC a nepahetseng a leka-lekanya ho ntlafatsa ts'ebetso ntle le ho sekisetsa thepa e 'ngoe.

4.2 Matla a ho khomarela:

Matla a tlamahano ea putty le stucco a bohlokoa haholo mabapi le hore na li tlamahane hantle hakae le li-substrates tse fapaneng. Liteko tsa ho hula le litekanyo tsa matla a tlamo li ile tsa etsoa ho hlahloba phello ea MHEC ho khomarela.

4.3 Beha nako:

Ho beha nako ke paramente ea bohlokoa e amang ts'ebeliso le ho omisoa ha putty le stucco. Phuputso ena e ile ea batlisisa hore na likhakanyo tse fapaneng tsa MHEC li ama nako ea ho beha le hore na ho na le mefuta e mengata e loketseng lits'ebetso tse sebetsang.

ha re phethela:

Phuputso ena e fana ka lintlha tsa bohlokoa mabapi le ho ntlafatsa li-putty le li-powder tsa gypsum ho sebelisa MHEC. Ka tlhahlobo e hlophisitsoeng ea liphello tsa MHEC mabapi le ho sebetsa, matla a tlamo le nako ea ho beha, thuto e ile ea bontša mokhoa o nepahetseng oa ho ntlafatsa ts'ebetso ka kakaretso. Liphuputso tsena li ka thusa ho nts'etsapele thepa ea moaho e ntlafalitsoeng ka ts'ebetso e ntlafalitsoeng le e tšoarellang.

Tsela e tlang:

Lipatlisiso tsa nako e tlang li ka hlahloba ho tšoarella ha nako e telele le boemo ba leholimo ba li-putty le li-stuccoes tse fetotsoeng tsa MHEC. Ho feta moo, liphuputso tse mabapi le ho khonahala ha moruo le ho ata ha litlolo tse ntlafalitsoeng li ka ts'ehetsa ts'ebeliso ea lisebelisoa tsena indastering ea kaho.
