Me yasa CMC ke taka muhimmiyar rawa a Masana'antar Samar da Takardu

Sodium carboxymethyl cellulose (CMC) yana taka muhimmiyar rawa a cikin masana'antar yin takarda saboda kaddarorin sa da ayyuka na musamman. Ga dalilin da ya sa CMC ke da mahimmanci wajen yin takarda:

1. Riƙewa da Taimakon Ruwa: CMC yana aiki azaman riƙewa da taimakon magudanar ruwa a cikin tsarin yin takarda. Yana inganta riƙe da ƙananan ƙwayoyin cuta, fibers, da additives a cikin takardun takarda, yana hana asarar su a lokacin samuwar da inganta rubutun takarda da daidaituwa. Hakanan CMC yana haɓaka magudanar ruwa ta hanyar ƙara yawan magudanar ruwa ta hanyar injin waya ta takarda, yana rage lokacin da ake buƙata don ƙirƙirar takarda da bushewa.
2. Wakilin Girman Ciki: CMC yana aiki azaman wakili mai ƙima na ciki a cikin ƙirar takarda, yana ba da juriya na ruwa da karɓar tawada ga takaddar da aka gama. Yana adsorbs akan filayen cellulose da ɓangarorin filler, suna samar da shingen hydrophobic wanda ke korar kwayoyin ruwa kuma yana rage shigar ruwa cikin tsarin takarda. Ƙirar ma'auni na tushen CMC yana haɓaka iya bugawa, riƙe tawada, da kwanciyar hankali na samfuran takarda, haɓaka dacewarsu don aikace-aikacen bugu da rubutu daban-daban.
3. Agent Sizing Sing: Ana amfani da CMC azaman wakili don haɓaka kayan aikin takarda, kamar santsi, sheki, da bugu. Yana samar da fim na bakin ciki a saman takardar takarda, cike da rashin daidaituwa da kuma rage porosity. Wannan yana haɓaka ƙarfin saman ƙasa, riƙe tawada, da ingancin buga takarda, yana haifar da fiɗafi, ƙarin hotuna da rubutu da aka buga. Ƙirƙirar ma'auni na tushen CMC kuma yana haɓaka santsi da iyawar takarda akan bugu da canza kayan aiki.
4. Rigar Ƙarshen Ƙarshen: A cikin rigar ƙarshen injin takarda, CMC yana aiki azaman ƙarar ƙarshen rigar don inganta ƙirar takarda da ƙarfin takarda. Yana inganta flocculation da riƙe da zaruruwa da filler, haifar da mafi kyawun samuwar takarda da daidaituwa. CMC kuma yana ƙara ƙarfin haɗin kai tsakanin zaruruwa, yana haifar da ƙarfin juriya na takarda, juriya, da fashe ƙarfi. Wannan yana haɓaka ingancin gabaɗaya da dorewa na samfurin takarda da aka gama.
5. Mai Rarraba Pulp da Agglomerate Inhibitor: CMC yana aiki azaman mai rarraba ɓangaren litattafan almara da mai hana agglomerate a cikin yin takarda, yana hana haɓakawa da sake haɓakar filaye na cellulose da tara. Yana tarwatsa zaruruwa da tara a ko'ina a ko'ina cikin jarin takarda, yana rage haɗar fiber da haɓaka ƙirar takarda da daidaituwa. Masu tarwatsawa na tushen CMC suna haɓaka ingantaccen sarrafa ɓangaren litattafan almara da rage faruwar lahani kamar tabo, ramuka, da ɗigo a cikin takarda da aka gama.
6. Surface Coating Binder: Ana amfani da CMC azaman mai ɗaure a cikin abubuwan da aka shafa na saman don takarda mai rufi da allo. Yana ɗaure ɓangarorin pigment, irin su calcium carbonate ko kaolin, zuwa saman ɓangaren takarda, suna yin santsi mai laushi. Rubutun tushen CMC suna haɓaka bugu, haske, da kaddarorin gani na takaddun da aka rufa, suna haɓaka kamanninsu da kasuwa a cikin ingantaccen bugu da aikace-aikacen marufi.
7. Dorewar Muhalli: CMC yana ba da fa'idodin muhalli a cikin masana'antar yin takarda azaman abin sabuntawa, mai yuwuwa, da ƙari mara guba. Yana maye gurbin ma'aunin sikelin roba, masu rarrabawa, da masu ɗaure fuska, rage tasirin muhalli na masana'anta da zubar da takarda. Samfuran takarda na tushen CMC ana iya sake yin amfani da su kuma ana iya yin takin su, suna ba da gudummawa ga ayyukan gandun daji masu dorewa da dabarun tattalin arziki madauwari.

sodium carboxymethyl cellulose (CMC) taka wani makawa rawa a cikin papermaking masana'antu ta inganta takarda samuwar, ƙarfi, surface Properties, printability, da muhalli dorewa. Kaddarorin sa na multifunctional sun sa ya zama abin ƙari don haɓaka inganci, aiki, da ƙwarewar kasuwa na samfuran takarda da takarda a aikace-aikace daban-daban.
