Tsarin Kauri na Cellulose a Turmi

Cellulose ether na iya inganta aikin rigar turmi sosai, kuma babban ƙari ne wanda ke shafar aikin ginin turmi. Kyakkyawan zaɓi na ethers cellulose na nau'i daban-daban, nau'i daban-daban, nau'o'in nau'in nau'i daban-daban, nau'i daban-daban na danko da adadin da aka kara za su sami tasiri mai kyau akan inganta aikin busassun busassun turmi.

Har ila yau, akwai kyakkyawar dangantaka ta layi tsakanin daidaituwar simintin siminti da kuma adadin ether cellulose. Cellulose ether na iya ƙara dankowar turmi sosai. Mafi girman sashi, mafi kyawun tasirin sakamako. High-danko cellulose ether ruwa bayani yana da babban thixotropy, wanda kuma shi ne babban hali na cellulose ether.

A thickening sakamako dogara a kan mataki na polymerization na cellulose ether, bayani maida hankali, karfi kudi, zazzabi da sauran yanayi. Kayan gelling na maganin ya keɓanta ga alkyl cellulose da abubuwan da aka gyara. Abubuwan gelation suna da alaƙa da matakin maye gurbin, ƙaddamar da bayani da ƙari. Don abubuwan da aka gyara na hydroxyalkyl, abubuwan gel ɗin kuma suna da alaƙa da canjin canjin hydroxyalkyl. 10% -15% bayani za a iya shirya don ƙananan danko MC da HPMC, 5% -10% bayani za a iya shirya don matsakaici-danko MC da HPMC, kuma 2% -3% bayani za a iya shirya kawai don high-danko MC. da HPMC. Yawancin lokaci rarrabuwar danko na cellulose ether kuma ana ƙididdige shi da 1% -2% bayani.

Ether mai nauyin nauyin kwayoyin halitta yana da babban tasiri mai kauri. Polymers tare da ma'auni daban-daban na kwayoyin halitta suna da danko daban-daban a cikin maganin taro iri ɗaya.

Dankowar sa yana da ɗan dogaro akan ƙimar juzu'i, kuma babban danko ya kai ga dankowar manufa, kuma adadin adadin da ake buƙata yana da ƙarami, kuma danko ya dogara da ƙimar girma. Sabili da haka, don cimma wani daidaituwa, dole ne a ba da garantin wani adadin ether cellulose (mahimmancin bayani) da danko bayani. Gel zafin jiki na maganin kuma yana raguwa a layi tare da karuwa da ƙaddamar da maganin, da gels a dakin da zafin jiki bayan kai wani taro. Matsakaicin gelling na HPMC yana da girma sosai a zafin jiki.
