2. Hydrophobic rubber powder Hydrophobic/hydrophobic

E. Ifayibha enganyangekiyo kwi-crack
Umthamo 0.2-0.5%

Inkcazo yezinto:
Idityaniswe ne-polystyrene/ipolyester njengeyona nto iphambili ekrwada ibe kuhlobo olutsha/ifayibha enganyangekiyo kwi-crack kwikhonkrithi kunye nodaka/ebizwa ngokuba “kukuqinisa okwesibini” kwekhonkrithi.

Iindidi eziphambili:

1. I-alkali-resistant glass fiber
2. Ifayibha yeVinylon (ifayibha yePVA)
3. Ifayibha yePolypropylene (ifayibha zePP)
4. Ifayibha ye-Akriliki (i-PAN fiber)

Ukusetyenziswa kophawu:

1. Ukumelana nokuqhekeka kunye nokuqina
2. Ukuxhathisa ukothuka
3. Umkhenkce kunye nokumelana nokunyibilika

F. Wood fiber
Umthamo 0.2-0.5%

Inkcazo yezinto:
Ifayibha yendalo enganyibilikiyo emanzini kunye nezinyibilikisi zezinto eziphilayo/ukuguquguquka okugqwesileyo/ukuhlakazeka

Iindidi eziphambili:
Ubude bosinga lomthi buqhele ukuba yi-40-1000um/ ingasetyenziswa kudaka olomileyo lomgubo

Iimbonakalo
1. Ukuxhathisa i-crack
2. Uphuculo
3. Ukuchasa ukuxhoma

G. I-arhente yokunciphisa amanzi
Umthamo 0.05-1%
Isongezo esinokunciphisa inani lokuxuba amanzi phantsi kwemeko yokugcina ukuhambelana kodaka ngokusisiseko okufanayo
1. I-arhente yokunciphisa amanzi eqhelekileyo
2. Isinciphisi samanzi esisebenza kakuhle
3. Amandla okuqala e-superplasticizer
4. Ukurhoxiswa kwe-superplasticizer
5. Isinciphisi samanzi esingenisa umoya
Ukurhoxiswa kwe-superplasticizer esebenza ngokufanelekileyo.

H. Defoamer
Umthamo 0.02-0.5%
Uncedo lokukhulula amaqamza omoya abanjelwe kwaye aveliswe ngexesha lokuxutywa kodaka kunye nokwakhiwa / ukuphucula amandla oxinzelelo / ukuphucula imeko yomphezulu
1. Iipolyols
2. I-Polysiloxane (1. ukuqhuma i-foam; 2. ukuthintela ukuvuselelwa kwe-foam)

I. Iarhente yamandla yangoko
Umthamo 0.3-0.7%
iqondo lobushushu eliphantsi lokuqala coagulant
icalcium formate
Ukukhawulezisa isantya sokuqina kwesamente, phucula amandla kwangethuba
