Hydroxyethylcellulose (HEC) ba ionic, polymer polymer mai narkewa da ruwa wanda aka samu daga cellulose. Ana yawan amfani da shi a masana'antu daban-daban kamar su magunguna, kayan kwalliya, abinci, da samfuran kulawa na sirri saboda kauri, daidaitawa, da abubuwan gelling.
Tsarin sinadarai na Hydroxyethylcellulose
HEC shine polymer cellulose da aka gyara, inda aka gabatar da ƙungiyoyin hydroxyethyl akan kashin bayan cellulose. Wannan gyare-gyare yana haɓaka haɓakar ruwa da sauran kaddarorin cellulose. Ƙungiyoyin hydroxyethyl (-CH2CH2OH) an haɗa su tare da ƙungiyoyin hydroxyl (-OH) na kwayoyin cellulose. Wannan gyare-gyare yana canza yanayin jiki da sinadarai na cellulose, yana sa ya dace da aikace-aikace masu yawa.
Halayen Flammability
1. Konewa
Tsaftataccen cellulose abu ne mai ƙonewa saboda ya ƙunshi ƙungiyoyin hydroxyl, waɗanda za su iya yin konewa. Koyaya, gabatarwar ƙungiyoyin hydroxyethyl akan kashin bayan cellulose yana canza halayen flammability. Kasancewar ƙungiyoyin hydroxyethyl na iya rinjayar halayen konewa na HEC idan aka kwatanta da cellulose da ba a canza ba.
2. Gwajin Flammability
Gwajin ƙonewa yana da mahimmanci don tantance haɗarin wuta da ke tattare da abu. Gwaje-gwaje daban-daban, kamar ASTM E84 (Tsarin Gwajin Daidaita don Halayen Ƙona Sama na Kayan Ginin) da UL 94 (Ma'auni don Kariyar Flammability na Kayan Filastik don Sassan Na'urori da Kayan Aiki), ana amfani da su don kimanta ƙonewar kayan. Waɗannan gwaje-gwajen suna tantance sigogi kamar yaduwar harshen wuta, haɓaka hayaki, da halayen kunnawa.
Abubuwan Da Suka Shafi Flammability

Kasancewar danshi zai iya rinjayar flammability na kayan. Kayayyakin Cellulosic yakan zama ƙasa da ƙonewa lokacin da suke ɗauke da matakan danshi mafi girma saboda ɗaukar zafi da yanayin sanyaya ruwa. Hydroxyethylcellulose, kasancewar ruwa mai narkewa, na iya ƙunsar da ɗanshi dabam dabam dangane da yanayin muhalli.
2. Girman Barbashi da yawa
Girman barbashi da yawa na abu na iya shafar flammability. Kayayyakin da aka raba gabaɗaya suna da mafi girman yanki, wanda ke haɓaka konewa cikin sauri. Koyaya, ana amfani da HEC galibi a cikin foda ko granulated nau'i tare da girman barbashi mai sarrafawa don saduwa da takamaiman buƙatun aikace-aikacen.
3. Kasancewar Additives

Yakamata a adana Hydroxyethylcellulose a cikin busasshiyar wuri mai cike da iska mai nisa daga tushen kunna wuta. Ya kamata a kula don hana kamuwa da zafi mai yawa ko hasken rana kai tsaye, wanda zai iya haifar da lalacewa ko ƙonewa.
2. Yarda da Ka'idoji

Hukumomin gudanarwa kamar Hukumar Kula da Tsaro da Lafiya ta Ma'aikata (OSHA) a Amurka da Hukumar Kula da Sinadarai ta Turai (ECHA) a cikin Tarayyar Turai suna ba da ƙa'idodi don amintaccen kulawa da amfani da sinadarai.
3. Matakan danne Wuta
Idan akwai wuta da ta ƙunshi hydroxyethylcellulose ko samfuran da ke ɗauke da HEC, yakamata a aiwatar da matakan kashe gobara da suka dace. Wannan na iya haɗawa da yin amfani da ruwa, carbon dioxide, busassun na'urorin kashe sinadarai, ko kumfa, ya danganta da yanayin wutar da kewaye.

Yayin da cellulose mai tsabta yana ƙonewa, ƙaddamar da ƙungiyoyin hydroxyethyl ya canza halayen flammability na HEC. Abubuwa kamar abun ciki na danshi, girman barbashi, yawa, da kasancewar abubuwan ƙari na iya yin tasiri ga flammability na samfuran hydroxyethylcellulose. Ma'ajiyar da ta dace, kulawa, da kuma bin ka'idodin aminci suna da mahimmanci don rage haɗarin wuta da ke hade da HEC. Ƙarin bincike da gwaji na iya zama dole don cikakken fahimtar halayyar flammability na hydroxyethylcellulose a ƙarƙashin yanayi daban-daban da ƙira.
