Waa maxay faraqa u dhexeeya HEC iyo HEMC?

HEC (Hydroxyethyl Cellulose) iyo HEMC (Hydroxyethyl Methyl Cellulose) waa labadaba polymers xeryahooda laga soo qaatay cellulose, oo ah polysaccharide si dabiici ah u soo baxa oo laga helo dhirta.Labaduba waxa loo isticmaalaa dhumucyada, xasiliyayaasha, iyo emulsifiers ee alaabooyin kala duwan, oo ay ku jiraan rinjiga iyo dahaarka, cuntada, dawooyinka, qurxinta, iyo codsiyada warshadaha.

Farqiga ugu weyn ee u dhexeeya HEC iyo HEMC waa qaabdhismeedka kiimikada.HEC waa derivative cellulose non-ionic, halka HEMC waa derivative ionic cellulose.HEC waxa ay ka kooban tahay hal koox oo hydroxyethyl ah oo ku xidhan laf dhabarta cellulose, halka HEMC ay ka kooban tahay laba kooxood oo hydroxyethyl ah oo ku xidhan laf dhabarta cellulose.

HEC waa polymer-ka biyaha ku milma oo loo isticmaalo sidii wakiilka dhumucyada ee alaabooyin kala duwan, oo ay ku jiraan rinjiga & dahaarka, cuntada, dawooyinka, iyo waxyaalaha la isku qurxiyo.Waxaa loo isticmaalaa in lagu kordhiyo viscosity ee badeecada, wanaajiso xasiloonida, iyo bixinta qaab siman.Waxa kale oo loo isticmaalaa emulsifier ahaan si ay uga ilaaliso maaddooyinka inay kala soocaan.

HEMC sidoo kale waa polymer-ka biyaha-milmi kara oo loo isticmaalo sidii walax dhumuc leh.Waxa loo isticmaalaa alaabooyin kala duwan, oo ay ku jiraan dhismo, cunto, dawooyin, iyo waxyaalaha la isku qurxiyo.Waxaa loo isticmaalaa in lagu kordhiyo viscosity ee badeecada, wanaajiso xasiloonida, iyo bixinta qaab siman.Waxa kale oo loo isticmaalaa emulsifier ahaan si ay uga ilaaliso maaddooyinka inay kala soocaan.

HEC waxaa inta badan loo isticmaalaa rinjiga iyo alaabta dahaadhka, halka HEMC aad loogu isticmaalo dhismaha iyo qurxinta.HEC waxay aad uga waxtar badan tahay kordhinta viscosity ee badeecada marka loo eego HEMC, sidoo kale waxay aad ugu xasilloon tahay xalalka acidic iyo alkaline.HEMC waxay aad uga waxtar badan tahay bixinta texture siman ee alaabta marka loo eego HEC, sidoo kale waxay aad u degan tahay heerkulka sare.

Marka la soo koobo, farqiga ugu weyn ee u dhexeeya HEC iyo HEMC waa qaabdhismeedka kiimikada.HEC waa derivative cellulose non-ionic, halka HEMC waa derivative ionic cellulose.HEC waxaa inta badan loo isticmaalaa rinjiga & dahaarka, alaabta saabuunta, halka HEMC inta badan loo isticmaalo dhismaha iyo qurxinta.HEC waxay aad waxtar ugu leedahay kordhinta viscosity ee alaabta, halka HEMC ay aad waxtar ugu leedahay bixinta qaab siman.
