Sidee loo hagaajiyaa tayada alaabta dhalaalaysa kulul?

Hadda caagadaha qaarkood waa kuwa fudud, sida polyetylen iyo polystyrene, iwm.

 

1. Ololka dib u dhiga

Waxyaalaha lagu daro ee wanaajin kara dib u dhaca ololkabalaastiig dhalaalaysa kululwaxa loo yaqaan dab-dejiyayaal. Inta badan balaastikada ay ku jiraan dib-u-celinta ololka ayaa is-damiya, ama si tartiib ah u guba. Dib-u-celinta ololka sida caadiga ah loo isticmaalo hadda waxaa ka mid ah antimony oxide, xeryahooda boron aluminium, iyo tetrachlorophthalic anhydride.

 

2. Saliid

Saliiduhu waa daroogo loo isticmaalo in lagu wanaajiyo soo saarista balaastigga inta lagu jiro kululaynta iyo qaabaynta, iyo hagaajinta dusha sare ee alaabta. Saliidaha inta badan la isticmaalo waa stearic acid, milix, paraffin iyo waxes synthetic.

 

3. Qalabka xoojinta iyo buuxinta

Balaastikooyin badan, agabka xoojinta iyo buuxinta waxay ku xisaabtamayaan qayb aad u badan, gaar ahaan balaastikada la xoojiyay iyo kuwa kalsiyumka caagga ah.

 

4. Midabeeyayaasha

Midabeeyayaasha waxaa loo isticmaalaa in lagu midabeeyo balaastikada kulul. Inta badan ee qurxinta iyo qurxinta. Qiyaastii 80% alaabooyinka balaastikada ah ayaa midabaysan si ay u soo saaraan badeecada ugu dambeysa.
