Mafi mahimmancin dukiya na ether cellulose shine riƙewar ruwa a cikin kayan gini. Ba tare da ƙari na ether cellulose ba, ƙaramin ɗan ƙaramin turmi na sabon turmi yana bushewa da sauri ta yadda siminti ba zai iya yin ruwa ta hanyar al'ada ba kuma turmi ba zai iya taurare kuma ya sami haɗin kai mai kyau ba. A lokaci guda kuma, ƙari na ether cellulose yana sa turmi ya sami kyakkyawan filastik da sassauci, kuma yana inganta ƙarfin haɗin gwiwa na turmi. Bari muyi magana game da tasiri akan aikace-aikacen busassun busassun turmi daga aikin samfurin cellulose ether.

1. The fineness na cellulose

Kyakkyawan ether cellulose yana rinjayar solubility. Alal misali, ƙananan fineness na cellulose ether, da sauri ya narke cikin ruwa da kuma inganta aikin riƙe ruwa. Saboda haka, ya kamata a haɗa da kyaun ether cellulose a matsayin ɗaya daga cikin abubuwan bincikensa. Gabaɗaya magana, ragowar sieve na cellulose ether fineness akan 0.212mm kada ya wuce 8.0%.

2. Bushewar yawan asarar nauyi

Matsakaicin asarar nauyi na bushewa yana nufin adadin yawan adadin abubuwan da aka rasa a cikin adadin asalin samfurin lokacin da aka bushe ether cellulose a wani zazzabi. Domin wani ingancin ether cellulose, da bushewa nauyi asara kudi ne da yawa, wanda zai rage abun ciki na aiki sinadaran a cellulose ether, shafi aikace-aikace sakamako na ƙasa Enterprises, da kuma kara sayan farashin. Yawancin lokaci, asarar nauyi akan bushewa na ether cellulose bai wuce 6.0%.

3. Sulfate ash abun ciki na cellulose ether

Don wani ingancin ether cellulose, abun cikin ash ya yi yawa, wanda zai rage abun ciki na sinadarai masu aiki a cikin ether cellulose kuma ya shafi tasirin aikace-aikacen kamfanoni na ƙasa. Abubuwan da ke cikin sulfate ash na cellulose ether wani muhimmin ma'auni ne na aikinsa. A hade tare da halin yanzu samar da halin yanzu na kasarta data kasance cellulose ether masana'antun, yawanci ash abun ciki na MC, HPMC, HEMC kada ya wuce 2.5%, da kuma ash abun ciki na HEC cellulose ether kada ya wuce 10.0%.

4. Dankowar cellulose ether

Riƙewar ruwa da kauri na cellulose ether ya dogara ne akan danko da adadin ether ɗin cellulose kanta da aka ƙara zuwa siminti.

5. Ƙimar pH na ether cellulose

Dankin samfuran ether na cellulose zai ragu sannu a hankali bayan an adana su a mafi girman zafin jiki ko na dogon lokaci, musamman ga samfuran da ke da ƙarfi, don haka ya zama dole don iyakance pH. Gabaɗaya, yana da kyau a sarrafa kewayon pH na ether cellulose zuwa 5-9.

6. Hasken watsawa na cellulose ether

Hasken wutar lantarki na ether cellulose yana rinjayar tasirin aikace-aikacensa a cikin kayan gini. Babban abubuwan da ke shafar tasirin hasken cellulose ether sune: (1) ingancin albarkatun kasa; (2) tasirin alkalization; (3) rabon tsari; (4) rabo mai ƙarfi; (5) sakamako na tsaka tsaki. Dangane da tasirin amfani, watsawar haske na ether cellulose bai kamata ya zama ƙasa da 80%.

7. Gel zafin jiki na cellulose ether

Ana amfani da ether na cellulose galibi azaman viscosifier, filastik da wakili mai riƙe ruwa a cikin samfuran siminti, don haka danko da zafin jiki na gel sune mahimman matakan da za a iya kwatanta ingancin ether cellulose. Ana amfani da zazzabi na gel don ƙayyade nau'in ether cellulose, wanda ke da alaƙa da matakin maye gurbin sauran ethers cellulose. Bugu da ƙari, gishiri da ƙazanta na iya rinjayar yawan zafin jiki na gel. Lokacin da zafin jiki na maganin ya tashi, polymer cellulose a hankali ya rasa ruwa, kuma dankon maganin yana raguwa. Lokacin da gel batu ya kai, da polymer ne gaba daya dehydrated da kuma samar da wani gel. Sabili da haka, a cikin samfuran siminti, yawanci ana sarrafa zafin jiki a ƙasa da zafin jiki na farko. A karkashin wannan yanayin, ƙananan zafin jiki, mafi girma da danko, kuma mafi mahimmancin tasirin kauri da riƙe ruwa.
