Qeexida walxaha:
Isku-dhafka polystyrene/polyester-ka oo ah alaabta ceeriin ee ugu weyn oo loo beddelo nooc cusub/fileeb u adkaysta shubka iyo hoobiye/loo yaqaan "xoojinta sare" ee shubka

Noocyada ugu muhiimsan:

1. Fiber galaas u adkaysta Alkali
2. Fiber Vinylon (PVA fiber)
3. fiber polypropylene (PP fiber)
4. Fiber Acrylic (PAN fiber)

Isticmaalka sifada:

1. Iska caabin dildilaaca iyo adkaynta
2. Iska caabin naxdin leh
3. Qabooji oo dhalaali caabbinta

F. Fiber alwaax
Qiyaasta 0.2-0.5%

Qeexida walxaha:
Fiber-dabiiciga ah oo aan ku milmin biyaha iyo dareerayaasha organic / dabacsanaan / kala firdhis heer sare ah

Noocyada ugu muhiimsan:
Dhererka fiber alwaax guud ahaan waa 40-1000um/waxaa loo isticmaali karaa hoobiye budada qalalan

Astaamaha
1. Iska caabin dildilaac ah
2. Kobcinta
3. Anti-laad-laadista

G. wakiilka biyaha dhimaya
Qiyaasta 0.05-1%
Wax lagu daro oo yarayn kara qadarka biyaha isku dhafka ah ee hoos yimaada xaalada ilaalinta joogteynta hoobiye asal ahaan isku mid ah
1. Wakiilka biyaha yareeya ee caadiga ah
2. Biyo yaraynta waxtarka sare leh
3. Awoodda hore ee superplasticizer
4. Dib u dhigista superplasticizer
5. Biyo yareeya hawo
Dib u dhigista wax ku oolnimada sare ee superplasticizer Yaraynta isticmaalka biyaha/kordhi cufnaanta hoobiye/shabkad.

H. Defoamer
Qiyaasta 0.02-0.5%
