Matsayin Sihiri na Polyacrylamide a Filin Yin Takarda

Polyacrylamidekalma ce gabaɗaya don homopolymers na acrylamide ko copolymers tare da wasu monomers. Yana daya daga cikin polymers masu narkewar ruwa da aka fi amfani dashi. Polyacrylamide yana samuwa a cikin nau'i na farin granules kuma ana iya rarraba shi zuwa nau'i hudu: wadanda ba ionic, anionic, cationic, da amphoteric ionic.

Aikace-aikace na Polyacrylamide a cikin Filin Yin Takarda

Tsarin yin takarda ya ƙunshi matakai da yawa, waɗanda suka haɗa da pulping, nunawa, tsaftacewa, tacewa, da ƙirƙira. A lokacin waɗannan matakan, ana haifar da ƙazanta iri-iri kamar fibers, filler, da tara. Idan ba a cire waɗannan ƙazanta da kyau daga ɓangaren litattafan almara ba, za su iya haifar da matsaloli kamar rashin magudanar ruwa da ƙarancin ƙarfin takarda. Ana amfani da polyacrylamide galibi azaman tarwatsawa, taimakon riƙewa, taimakon magudanar ruwa, flocculant, da wakili mai ƙima a cikin aikin yin takarda.

Ⅰ. Watsewa

Ƙara tarwatsawar polyacrylamide yayin aikin yin takarda zai iya hana haɓakar zaruruwa yadda ya kamata kuma inganta daidaiton takarda. Ƙananan adadin ƙarawa zai iya inganta kyakkyawan tarwatsawa na zaruruwan takarda da kuma cimma kyakkyawan sakamako na ƙirƙirar takarda. Hakanan zai iya inganta daidaitaccen ɓangaren ɓangaren litattafan almara da taushin takarda, da haɓaka halayen ƙarfin takarda. Ya dace da samfuran takarda na gida daban-daban kamar takarda bayan gida, adibas, kyallen fuska, da sauran takaddun siririn. A wasu masana'antun takarda, zai iya maye gurbin Polyethylene Oxide (PEO).

Ⅱ. Taimakon Riƙewa

Ana amfani da PAM akai-akai azaman taimakon riƙewa a cikin masana'antar yin takarda don haɓaka ƙimar riƙe fiber da rage zubar da ruwa. Ka'idar aikinsa ita ce samar da manyan flocs tare da ƙananan barbashi, waɗanda za'a iya cire su cikin sauƙi daga ɓangaren litattafan almara ta hanyar tacewa ko lalata.

Ⅲ. Taimakon Ruwa

PAM kuma na iya zama taimakon magudanar ruwa a cikin aikin yin takarda. Yana ƙara yawan magudanar ruwa, yana ba da damar sauri da inganci na dewatering takarda akan injin takarda. Wannan yana taimakawa wajen haɓaka saurin samarwa da rage yawan amfani da makamashi ta hanyar rage lokacin bushewa da ake buƙata don takarda.

Ⅳ. Wakilin Girmamawa

A wasu lokuta, ana amfani da polyacrylamide azaman wakili mai ƙima a cikin yin takarda don sarrafa shigar ruwa da sauran ruwaye cikin takardar takarda. Wannan yana taimakawa wajen samun kaddarorin da ake so kamar juriya na ruwa da riƙe tawada, musamman a aikace-aikacen da takarda ke buƙatar jure ɗanshi ko ayyukan bugu.

Ⅴ. Flocculant

A yayin aiwatar da aikin jiyya na ruwa a cikin injina na takarda, ana iya amfani da polyacrylamide azaman flocculant don cire daskararru da aka dakatar da gurɓataccen ruwa a cikin ruwan datti. Yana taimakawa wajen samar da barbashi masu girma da ake kira flocs, wanda za'a iya cire su cikin sauƙi ta hanyar lalata ko tacewa. Wannan yana ba da gudummawar rage gurɓataccen ruwa da haɓaka dorewar muhalli na kasuwancin yin takarda.

Gabaɗaya, ƙayyadaddun kaddarorin polyacrylamide sun sa ya zama ƙari mai mahimmanci a cikin masana'antar yin takarda, yana ba da gudummawa ga ingantacciyar inganci, ingancin samfur, da aikin samfuran takarda. Aiwatar da polyacrylamide a cikin filin yin takarda ya mamaye dukkan sarkar masana'antar yin takarda, daga samar da takarda zuwa jiyya na ruwa. Ba wai kawai inganta inganci da samar da takarda ba, yana rage farashin samarwa, amma kuma yana ba da gudummawa mai kyau ga kare muhalli.
