Hunhu hwekuparadzira dhayi:
Kusiyana nemamwe marudzi mazhinji edhayi, madhayi anoparadzira haanyanyi kunyungudika nemvura pane mamwe madhayi akadai sedhayi asidhi. Naizvozvo, madhayi ekuparadzira anonyanya kushandiswa mukudhaya mhinduro dzekugezesa.Tamol NNinoshanda zvakanyanya kana nzira yekudhaya ichiitwa pakupisa kwakanyanya. Kunyanya, mhinduro dzakatenderedza 120 ° C kusvika 130 ° C dzinopa kushanda kwakakwana kuparadzira dhayi, zvichiita kuti dziwedzere kugovaniswa uye dzinobata maziso, nepo.Tamol NNzvinogona kukonzera kusaenzana uye kushomeka kwemavara kune tembiricha yakaderera.
Ndezvipi zvinoshandiswa zvekuparadzira dhayi?Tamol NN
Nekuda kwehunhu hwawo hwemakemikari uye maitiro akatsanangurwa pamusoro, madhayi ekuparadzira anowanzo shandiswa kudhaya mafiber ekugadzira, akadai sepolyester, naironi, acrylic, uye acetate. Mazhinji mafomu epolyester ane hydrophobic uye anoshaya ionic zvivakwa, zvichiita kuti zvisave zvisingagoneke kupendeka nechero chinhu kunze kwekuparadzira dhayi.
Mukuwedzera, polyester fibers haiwedzere pane zvakajairwa tembiricha kunyangwe ikanyudzwa mubhati redhayi, zvichiita kuti zviome kuti mamorekuru edhayi adyidzane nezvinhu. Kunyangwe pakuvira kwekushisa (100°C), kudhayiwa kwepolyester kune matambudziko.
Naizvozvo, pakudhaya polyester, madhayi anoparadzira anoshandiswa mukudhaya zvigadziriso zvekugezesa patembiricha 20 kusvika 30 madhigirii akakwira kupfuura nzvimbo yekubikira yedhayi yekugezesa mhinduro. Disperse madhayi anozivikanwa kuchengetedza mamolecular kutendeseka patembiricha yepamusoro inodiwa kupenda mapolyester. Nechikonzero chimwe chete madhayi ekuparadzira anoshandiswa kupenda mapolyester, anoshandiswawo kupenda zvimwe zvisiri-ionic synthetic zvinhu. Icho chokwadi chekuti madhayi anoparadzira haana cationic kana anionic tendencies ingangove ndiyo inonyanya kupatsanurwa midziyo yekuparadzira dhayi.
Disperse madhayi anogona zvakare kushandiswa mumarasi uye mapurasitiki kune epamusoro uye zvakajairika kupenda zvinangwa.
