Ko te tikanga here matua okonutai hexametaphosphate, konutai hexametaphosphatei muri i te ngongo wai i roto i te viscose, he hononga tata ki nga ahuatanga okonutai hexametaphosphateake, te tauira mokonutai hexametaphosphateno tetahi momo hanganga o te phosphate,konutai hexametaphosphateHe nui te taumaha o te ngota anion, ko te nuinga kei roto ko te tau ira PO3 he 20-100 te teitei, ka hanga he mekameka roa.
Nga tikanga whakahaere:
1. Tīpakohia nga momo whakauru kia rite ki nga whakaritenga mahi raima
2. Me whakatau te inenga o te whakauru ma te whakataetae whakamatautau
3. Whakaatuhia nga mahi hangarau ki nga kaimahi i mua i te tiimata o te mahi.
4. Whakaritea he tangata motuhake hei tirotiro i te mahi ine
5. Whakaritea te nui o te whakauru mo tenei mahi
