Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) shine ether cellulose mai narkewa mara ionicabubuwan da aka samo asaliwanda zai iya zama tare tare da wasu polymers masu narkewa da ruwa, surfactants, da salts. HEC yana da kaddarorin thickening, dakatarwa, adhesion, emulsification, barga samuwar fim, watsawa, riƙewar ruwa, kariyar ƙwayoyin cuta da kariyar colloidal. Ana iya amfani da shi sosai a cikin sutura, kayan kwalliya, hako mai da sauran masana'antu.

CHaracteristics na HEC

1.Kauri

HEC shine madaidaicin thickener don sutura da kayan shafawa. A cikin aikace-aikace masu amfani, haɗuwa da thickening da dakatarwa, aminci, tarwatsawa, da riƙewar ruwa zai haifar da mafi kyawun tasiri.

2.Pseudoplasticity

Pseudoplasticity yana nufin kadarorin da dankon maganin ya ragu tare da karuwa a cikin sauri. Latex Paint dauke da HEC yana da sauƙin amfani tare da goge ko rollers kuma yana iya ƙara sulɓi na saman, wanda kuma zai iya ƙara yawan aikin aiki; shampoos dake dauke da HEC suna da ruwa mai kyau kuma suna da danko sosai, da saukin tsomawa, da saukin watsewa.

3.Haƙuri gishiri

HEC yana da kwanciyar hankali sosai a cikin mafitacin gishiri mai girma kuma ba zai rushe cikin yanayin ionic ba. An yi amfani da shi a cikin lantarki, saman sassan da aka yi da shi zai iya zama cikakke kuma mai haske. Abin da ya fi dacewa shi ne cewa har yanzu yana da danko mai kyau idan aka yi amfani da shi a cikin launi na latex wanda ya ƙunshi borate, silicate da carbonate.

4.Samar da fim

Ana iya amfani da kayan aikin fim na HEC a yawancin masana'antu. A cikin ayyukan yin takarda, shafa tare da wakili mai glazing mai ɗauke da HEC zai iya hana shigar da man shafawa, kuma ana iya amfani da shi don shirya mafita don wasu al'amuran masana'antar takarda; a cikin kadi tsari, HEC iya ƙara elasticity na zaruruwa da kuma rage inji lalacewa da su. A cikin ma'auni, rini da karewa na masana'anta, HEC na iya aiki a matsayin fim mai kariya na wucin gadi. Lokacin da ba a buƙatar kariyarsa, ana iya wanke shi daga zaren da ruwa.

5.Riƙewar ruwa

HEC yana taimakawa wajen kiyaye danshi na tsarin a cikin yanayin da ya dace. Saboda ƙananan HEC a cikin maganin ruwa na ruwa zai iya samun sakamako mai kyau na ruwa, don haka tsarin ya rage yawan buƙatar ruwa a lokacin batching. Idan ba tare da riƙe ruwa da mannewa ba, turmin siminti zai rage ƙarfinsa da haɗin kai, kuma yumbu zai rage yuwuwar sa ta wani matsi.
