2. Mānoanoa
3. Hoʻonui i ka ikaika pili
4. E hoʻomaikaʻi i ka hana kūkulu

C. Starch etera
0.01-0.1%

Wehewehe mea:
Hiki ke hoʻololi i ka paʻa o nā morta e pili ana i ka gypsum/cement a me ka lime / hoʻololi i ka hana a me ka pale ʻana o nā morta.

ʻO nā ʻano nui:
Hoʻohana pinepine ʻia me ka cellulose ether

Hoʻohana hiʻona:
1. Mānoanoa
2. E hoʻomaikaʻi i ke kūkulu ʻana
3. Anti-sagging
4. Paheʻe pale

D. Hydrophobic pauda
0.2-0.3%

Wehewehe mea:
ʻO nā polymers ma muli o ka Silane

ʻO nā ʻano nui:
1. ʻO nā paʻakai metala momona
2. Hydrophobic lāʻau pauka Hydrophobic/hydrophobic

E. ka pulupulu paakiki
0.2-0.5%

Wehewehe mea:
Hoʻohui ʻia me ka polystyrene/polyester ma ke ʻano he mea maka nui i loko o kahi ʻano hou / ʻāʻī-kūpaʻa i ka fiber no ke kaʻa a me ka mortar / i kapa ʻia ʻo ka "hoʻoikaika lua" o ke koʻi.

ʻO nā ʻano nui:

1. Alkali-pale aniani puluniu
2. Uila Vinylon (PVA fiber)
3. Polypropylene fiber (PP fiber)
4. ʻO ka fiber Acrylic (PAN fiber)

Hoʻohana hiʻona:

1. Ke kū'ē i ka māwae a me ka paʻakikī
2. Kūʻē haʻalulu
3. Pa'a a ho'olulu

F. Uila laau
0.2-0.5%

Wehewehe mea:
ʻAʻole hiki ke hoʻoheheʻe ʻia ka fiber maoli i ka wai a me nā mea hoʻoheheʻe kūlohelohe

ʻO nā ʻano nui:
ʻO ka lōʻihi o ka lāʻau ka lōʻihi o 40-1000um / hiki ke hoʻohana ʻia i ka lepo lepo maloʻo

Nā hiʻohiʻona
1. Paʻa māwae
2. Hoʻonui
3. Anti-kauʻi

G. Mea hoemi wai
0.05-1%
ʻO kahi mea hoʻohui e hiki ke hōʻemi i ka nui o ka hui ʻana i ka wai ma lalo o ke ʻano o ka mālama ʻana i ka paʻa o ka mortar ma ke ʻano like.
1. Mea ho'ēmi wai maʻamau
2. Mea ho'ēmi wai kiʻekiʻe
3. Superplasticizer ikaika mua
4. Hoʻopaneʻe i ka superplasticizer
5. Ea-entraining wai emi
Hoʻopaneʻe i ka superplasticizer kiʻekiʻe E hoʻemi i ka hoʻohana wai/hoʻonui i ka paʻa o ka mortar/ka.

H. Defoamer
0.02-0.5%
Kōkua i ka hoʻokuʻu ʻana i nā ʻōpū ea i hoʻopaʻa ʻia a hana ʻia i ka wā o ka hui ʻana a me ka hana ʻana/hoʻomaikaʻi i ka ikaika compressive/hoʻomaikaʻi i ke kūlana o ka ʻili.
1. Nā Polyols
2. Polysiloxane (1. e uha'i i ka hu'a; 2. e pale i ka hana hou 'ana o ka hu'a)

I. Agena ikaika mua
0.3-0.7%
haʻahaʻa wela mua coagulant
calcium formate
E hoʻoikaika i ka wikiwiki paʻakikī sima, e hoʻomaikaʻi i ka ikaika mua

J. Polyvinyl alcohol
He mea hoʻopaʻa kiʻiʻoniʻoni hiki ke hoʻoheheʻe ʻia i ka wai
ʻO ka pauka waiʻona polyvinyl
PVA 17-88/PVA 24-88
1. Hoʻopaʻa
2. Hoʻokumu kiʻiʻoniʻoni
3. ʻAʻole kūʻē i ka wai
Hoʻohana ʻia no ka putty o loko a me waho o ka pā, ka mea hana interface, etc.
