Gutanga amazi ya hydroxyethyl cellulose ether mu gisubizo cy'amazi

Hydroxyethyl cellulose (HEC)Iguma ishonga cyane mu mazi mu bushyuhe bwinshi, ndetse no mu turere dushyuha cyane aho izindi ether za cellulose zitari ionic zihinduwe nka methyl cellulose (MC) na hydroxypropyl methyl cellulose (HpMC) zigaragaza ingingo z’ubushyuhe. Kugira ngo hamenyekane impamvu HEC ishobora gushonga cyane, hasuzumwe ubushyuhe bw’amazi nH kuri buri gice cya glucopyran mu bipimo bya HEC mu bushyuhe bukurikira kuva kuri 10 kugeza kuri 70 °C hakoreshejwe ibipimo bya dielectric spectrum bipima inshuro nyinshi cyane kugeza kuri 50 GHz.
Muri ubu bushakashatsi, ingero za HEC zasuzumwe ku mubare wa molar wa hydroxyethyl substitutions (MS) wa buri gice cya glucose pyran kiri hagati ya 1.3 na 3.6. Ingero zose za HEC zashongeshejwe mu mazi mu rugero rw'ubushyuhe bwasuzumwe kandi nta ngingo z'ubushyuhe zagaragaye. Agaciro ka nH k'ingero za HEC hamwe na MS 1.3 ni 14 kuri 20 °C, kandi kagabanuka buhoro buhoro uko ubushyuhe buzamuka, kandi kagabanuka kagera kuri 10 kuri 70 °C. Agaciro ka PH k'ingero za HEC kararuta agaciro gato ka nH gakenewe kagera kuri 5 ethers za cellulose nka MC na HpMC zigomba gushongeshwa mu mazi, ndetse no mu rugero rw'ubushyuhe bwinshi.
Icyakora, molekile za HEC zirashonga mu mazi mu bushyuhe bwinshi. Ubushyuhe bwa nH bw'ibipimo bya HEC na triglycol (ibice by'icyitegererezo bya HEC substituents) ni buke kandi birasa. Iyi ngingo igaragaza cyane ko imyitwarire y'amazi/kubura amazi mu bipimo bya HEC igenzurwa ahanini n'amatsinda yabyo yasimbuwe. 3 ni 14 kuri 20 °C, igabanuka buhoro buhoro uko ubushyuhe buzamuka, ikagabanuka ikagera kuri 10 kuri 70 °C. Agaciro ka nH k'icyitegererezo cya HEC karuta agaciro gato ka nH gakenewe kagera kuri 5 ethers za selulosi nka MC na HpMC zigomba gushonga mu mazi, ndetse no mu bushyuhe bwinshi. Molekile za HEC, ariko, zirashonga mu mazi mu bushyuhe bwinshi. Ubushyuhe bwa nH bw'ibipimo bya HEC na triglycol (ibice by'icyitegererezo bya HEC substituents) ni buke kandi birasa.
Iyi ngingo igaragaza cyane ko imyitwarire y’amazi mu bipimo bya HEC igenzurwa ahanini n’amatsinda yabyo yasimbuwe. 3 ni 14 kuri 20 °C, igabanuka buhoro buhoro uko ubushyuhe buzamuka, ikagabanuka ikagera kuri 10 kuri 70 °C. Agaciro ka nH k’icyitegererezo cya HEC kararuta agaciro gato ka nH gakenewe kagera kuri 5 ethers za selulosi nka MC na HpMC zigomba gushonga mu mazi, ndetse no mu bushyuhe bwinshi. Icyakora, molekile za HEC zirashonga mu mazi mu bushyuhe bwinshi. Ubushyuhe buterwa na nHHECingero na triglycol (icyitegererezo cy’ibice bisimbura HEC) ni byoroshye kandi bisa. Iyi ngingo igaragaza cyane ko imyitwarire y’amazi/kubura amazi mu ngero za HEC igenzurwa ahanini n’amatsinda yazo yasimbuwe.
Agaciro ka nH k'icyitegererezo cya HEC karuta agaciro ka nH gakomeye gashoboka kagera kuri 5. Etha za selulosi nka MC na HpMC zigomba gushonga mu mazi, ndetse no mu bushyuhe bwinshi. Molekyuli za HEC, ariko, zirashonga mu mazi mu bushyuhe bwinshi. Ubushyuhe bwa nH bw'ibipimo bya HEC na triglycol (icyitegererezo cy'ibisimbura HEC) ni buke kandi birasa.
