Methyl hydroxyethyl cellulose (MHEC)wani sinadari ne mai suna cellulose ether wanda ba ionic ba wanda ake amfani da shi sosai wajen gina tsarin turmi. Saboda kyawun kauri, riƙe ruwa, iya aiki da kuma dacewarsa, MHEC ta zama ɗaya daga cikin ƙarin abubuwa masu mahimmanci a cikin turmi mai gauraye da busasshe, musamman a cikin manne na tayal, turmi na plaster, turmi na ƙasa, turmi mai daidaita kansa da sauran kayayyaki.
1. Hanyar aikin MHEC a turmi
MHEC, a matsayin wani abu mai narkewa a ruwa, zai iya samar da ruwan da ke da ƙamshi iri ɗaya ko kuma colloid a cikin turmi. Idan aka ƙara shi a cikin turmi mai gauraye busasshe kuma ya haɗu da ruwa, MHEC yana narkewa da sauri, wanda hakan ke shafar halayen rheological na turmi, tsarin ruwan siminti, riƙe ruwa da halayen haɗin gwiwa. Babban tsarin aikinsa ya haɗa da waɗannan abubuwan:
Tasirin kauri: MHEC yana samar da maganin danko mai yawa bayan narkewa a cikin ruwa, wanda zai iya ƙara danko na tsarin turmi sosai, ta haka yana inganta jin daɗin gini da kaddarorin hana yin kasa;
Tasirin riƙe ruwa: MHEC yana da kyakkyawan ƙarfin riƙe ruwa, wanda zai iya rage asarar haɗa ruwa, tabbatar da cikakken ruwan siminti, gypsum da sauran kayan siminti, da kuma inganta haɓaka ƙarfi;
Inganta aikin shafawa da ginin: Kwayoyin Cellulose ether suna samar da wani nau'in man shafawa a cikin tsarin turmi, wanda ke taimakawa wajen amfani da kuma yaɗa turmi kuma yana inganta ingancin gini;
Tasirin daidaita kumfa: MHEC na iya daidaita wasu kumfa yayin aikin haɗawa, kuma adadin ƙananan kumfa masu dacewa na iya inganta aiki da riƙe ruwa na turmi;
Jinkirin coagulation: MHEC yana da wani tasiri na jinkiri akan ruwan siminti, wanda ke taimakawa wajen tsawaita lokacin aiki.
2. Ingantaccen aikin turmi ta MHEC
2.1. Inganta aikin gini
Aikin ginin turmi muhimmin alama ne don auna sauƙin amfaninsa. MHEC yana inganta mannewa da kuma man shafawa na turmi mai jika, wanda hakan ke sauƙaƙa gina shi. Musamman a cikin turmi mai manne da kuma turmi mai laushi, yana iya rage lanƙwasa sosai da kuma inganta daidaiton amfani.
2.2. Ingantaccen aikin riƙe ruwa
Rike ruwa yana ɗaya daga cikin muhimman halayen MHEC. A cikin wuraren da ke da ramuka masu ramuka (kamar tubali da siminti) ko kuma wuraren bushewa masu zafi, ruwa yana sha ko kuma yana ƙafewa da sauri, wanda ke shafar amsawar ruwan siminti. MHEC yana kulle danshi yadda ya kamata ta hanyar ƙirƙirar fim ɗin ruwa, yana rage zubewar ruwa da raguwar sa, da kuma inganta ƙarfin turmi da mannewa.
2.3. Inganta ƙarfin haɗin kai
MHEC yana inganta daidaito da yanayin ruwa na turmi, yana samar da tsari mai kyau tsakanin turmi da substrate da kayan saman (kamar tayal), wanda ke taimakawa wajen inganta ƙarfin haɗin kai. Musamman a cikin manne na tayal masu aiki sosai, MHEC na iya aiki tare da emulsions na polymer (kamar foda latex mai sake rarrabawa).
2.4. Inganta aikin hana lanƙwasawa
A lokacin gina facade, turmi yana iya yin lanƙwasa saboda nauyi, wanda ke shafar sarrafa kauri da kyawunsa. MHEC yana ba da kyakkyawan aikin hana lanƙwasa, yana ba turmi damar kiyaye siffarsa a bango, wanda yake da mahimmanci musamman ga manyan tayal da yadudduka masu kauri.
2.5. Inganta kwanciyar hankali a ajiya da kuma busasshen foda mai tsafta
MHEC mai inganci yana da kyakkyawan watsewar busasshiyar foda da kuma haɗakarwa iri ɗaya, ba abu ne mai sauƙi a tara ba, kuma yana da amfani ga tsari mai ɗorewa da adana samfuran turmi na dogon lokaci.
3. Halayen amfani da MHEC a cikin tsarin turmi daban-daban
Manna Tile
MHEC yana inganta aikin gini, aikin hana zamewa da lokacin buɗewa, kuma yana ƙara mannewa ga tayal.
Turmin filastik
Inganta santsi na gogewa, inganta riƙe ruwa, da kuma hana yin foda da tsagewa.
Turmi na bene
Inganta ruwa da kuma aikin daidaita kai don tabbatar da kauri ɗaya.
Turmi mai daidaita kai
Kula da ruwa, hana rabuwa, da kuma tabbatar da cewa saman ya yi daidai.
Turmi mai hana zafi
A cikin tsarin sanyaya iska mai sauƙi, MHEC yana tabbatar da rarrabawar slurry iri ɗaya, yana inganta haɗin kai da riƙe ruwa.
4. Gargaɗi game da amfani
Ƙarin iko akan adadin da aka kashe: Adadin ƙarin MHEC yawanci shine 0.2% ~ 0.5%, wanda ke buƙatar a daidaita shi bisa ga dabarar da buƙatun gini;
Bukatun Watsawa: Domin a ba da cikakken wasa ga aikinta, ana buƙatar a rarraba MHEC daidai gwargwado yayin aikin haɗawa;
Dacewa da sauran ƙari: Ya kamata a mai da hankali kan haɗin gwiwa tsakanin MHEC da foda na latex, retarder, defoamer da sauran ƙari don guje wa tasirin juna.
Methyl hydroxyethyl cellulose, a matsayin cellulose ether mai inganci, yana nuna kyakkyawan aiki a tsarin turmi. Ba wai kawai yana inganta aikin gini, kwanciyar hankali na zahiri da ƙarfin ƙarshe na turmi ba, har ma yana taka muhimmiyar rawa wajen haɓaka masana'antu da kuma kore kayayyakin turmi masu busassun gauraye. Yayin da kayan gini ke haɓaka zuwa babban aiki da kariyar muhalli,Amfani da MHEC zai zama mafi faɗi da zurfi.
