Liplaster le Li-render tse Phahameng: Kamoo RDP le Cellulose Ethers li Ntlafatsang Tshebetso

Kahong ea sejoale-joale, Phofo ea Polymer e ka Qhibilihang Bocha (RDP) e kopantsoe le li-ether tsa selulose E fana ka lintlafatso tse fetolang papali ho plaster le render mortars. Litlatsetso tsena tse sebelisanang li sebetsana le mathata a tloaelehileng - ho khomarela ho fokolang, ho petsoha, ho kenella ha metsi le ts'ebeliso e sa tsitsang - e leng se etsang hore e be ea bohlokoa bakeng sa borakontraka, litsebi le bahlahisi.

1. Ke Hobane'ng ha ho Sebedisa RDP ho Diplaster le Dirender?

• Khomarelo le Momahano e Ntlafalitsoeng: RDP e etsa filimi e tenyetsehang ea polymer ha e hasana hape, e ntlafatsa khokahano ea mechine le ea lik'hemik'hale ho li-substrate tse kang konkreite le setene

• Ho Ntlafatsa ho Tenyetseha le Khanyetso ea Mapetso: Marangrang a polymer a monya metsamao ea sebopeho le ho feto-fetoha ha mocheso, a fokotsa haholo ho petsoha ha manyane
• Ho Thibela Metsi ka Tsela e Phahameng: Filimi ea RDP e hanela ho kena ha mongobo, e ntlafatsa ho thibela metsi bakeng sa lifatše tsa kantle le libaka tse mongobo.

2. Tšebelisano-'moho le Cellulose Ethers

• Rheology e Laoloang le ho Boloka Metsi: Li-ether tsa cellulose (mohlala, HPMC, MHEC) li laola ho teteana, li thibela ho kobeha, 'me li boloka mongobo o tsitsitseng nakong ea ho fola—e leng tsa bohlokoa bakeng sa ho thehoa ha filimi ea polymer hantle.

• Tšebeliso e Boreleli le Qetello: Ho boloka seretse se kopane, li tšehetsa bokaholimo bo boreleli, bo lekanang—bo loketseng bakeng sa ho qeta ho etsa litšoantšo tsa boleng bo holimo

3. Melemo ea Bohlokoa Tšebelisong e Sebetsang

Ho khomarela le ho tšoarella

Li-plaster le li-render tse nang le RDP li bontša ho khomarela ho matla ha substrate, esita le libakeng tse boreleli kapa tse monyehang hanyane, li fokotsa ho arohana le ho ntlafatsa nako e telele.

Khanyetso ea Mapetso

Filimi ea RDP e tenyetsehang le ho boloka metsi hantle li thibela ho petsoha ho amanang le khatello ea maikutlo ha nako e ntse e ea, li boloka botsitso ba sebopeho

Ho Hanela Metsi le Tšireletso ea Boemo ba Leholimo

Li-mortar tsena li hanela ho kenella ha metsi, li fokotsa mathata a mongobo a kang efflorescence kapa hlobo lits'ebetsong tsa kantle. .

Boleng ba ho Sebetsa le ho Qetela

Motsoako o leka-lekaneng hantle o fana ka botsitso bo boreleli, bo loketseng trowel le nako e telele ea ho bula, o fokotsa boiteko ba basebetsi le ho netefatsa hore liphetho li ntle haholo.

Qetello

Ka ho kopanya RDP le cellulose ethers, plaster le render mortars li fihlella:

• E tiile ho khomarela libakeng tse fapaneng

• Khanyetso ea mapetso ka marangrang a tenyetsehang a polymer

• E ntlafalitsoe ho thibela metsi le ho tšoarella ha boemo ba leholimo

• E ntlafalitsoe bokhoni ba ho sebetsa le boleng ba bokaholimo
