Tsarin Kauri na Cellulose a cikin Turmi

Cellulose etherzai iya inganta aikin turmi mai jika sosai, kuma babban ƙari ne wanda ke shafar aikin ginin turmi. Zaɓin da ya dace na ethers cellulose iri-iri, viscosities daban-daban, girman barbashi daban-daban, matakan danko daban-daban da ƙarin adadi zai yi tasiri mai kyau akan inganta aikin turmi busasshe.

Akwai kuma kyakkyawar alaƙa tsakanin daidaiton manna siminti da kuma yawan sinadarin cellulose ether. Cellulose ether na iya ƙara yawan sinadarin turmi sosai. Mafi girman yawan sinadarin, haka tasirin yake. Maganin ruwa mai ƙarfi na cellulose ether yana da sinadarin thixotropy mai yawa, wanda kuma babban siffa ne na cellulose ether.

Tasirin kauri ya dogara ne da matakin polymerization na cellulose ether, yawan ruwan da ke cikinsa, saurin yankewa, zafin jiki da sauran yanayi. Siffar gel na maganin ya kebanta da cellulose na alkyl da kayan da aka gyara. Siffar gel yana da alaƙa da matakin maye gurbinsa, yawan ruwan da aka gyara da ƙari. Ga kayan da aka gyara na hydroxyalkyl, siffar gel ɗin kuma tana da alaƙa da matakin gyara na hydroxyalkyl. Ana iya shirya maganin 10%-15% don ƙarancin ruwan da ke cikin MC da HPMC, ana iya shirya maganin 5%-10% don matsakaicin ruwan da ke cikin MC da HPMC, kuma ana iya shirya maganin 2%-3% kawai don babban ruwan da ke cikin MC da HPMC. Yawanci ana kuma kimanta rarrabuwar danko na cellulose ether ta hanyar maganin 1%-2%.

Nauyin ƙwayoyin halitta mai yawacellulose etheryana da ingantaccen kauri sosai. Polymers masu nauyin kwayoyin halitta daban-daban suna da bambance-bambancen gesso a cikin maganin tattarawa iri ɗaya. Babban mataki. Ana iya cimma ɗanko mai manufa ne kawai ta hanyar ƙara babban adadin cellulose ether mai ƙarancin nauyin kwayoyin halitta. Danko mai shi ba shi da dogaro da ƙimar yankewa, kuma babban danko ya kai ga ɗanko mai manufa, kuma adadin ƙarin da ake buƙata ƙarami ne, kuma ɗanko ya dogara da ingancin kauri. Saboda haka, don cimma daidaito, dole ne a tabbatar da wani adadin cellulose ether (tattarawar maganin) da ɗanko mai mafita. Zafin gel na maganin kuma yana raguwa a layi tare da ƙaruwar yawan maganin, da gels a zafin ɗaki bayan ya kai wani takamaiman gesso. Yawan gelling na HPMC yana da girma sosai a zafin ɗaki.
