Tasirin fineness MC akan turmi

Ana buƙatar MC da aka yi amfani da shi don busassun busassun turmi don zama foda, tare da ƙananan abun ciki na ruwa, kuma fineness kuma yana buƙatar 20% ~ 60% na girman barbashi ya zama ƙasa da 63um. Rashin lafiya yana rinjayar solubility na methyl cellulose ether. M MC yana yawanci a cikin nau'i na granules, kuma yana da sauƙi a narke cikin ruwa ba tare da haɓakawa ba, amma yawan narkewa yana da jinkirin, don haka bai dace da amfani da busassun busassun turmi ba.

A busasshen turmi foda, MC yana tarwatsewa tsakanin aggregates, filaye masu kyau da siminti da sauran kayan siminti. Kyakkyawan isasshen foda kawai zai iya guje wa methyl cellulose ether agglomeration lokacin haɗuwa da ruwa. Lokacin da aka ƙara MC da ruwa don narkar da agglomerates, yana da wuyar tarwatsawa da narkewa. M MC ba kawai ɓatacce ba ne, amma kuma yana rage ƙarfin gida na turmi. Lokacin da aka shafa irin wannan busasshen turmi a cikin wani babban yanki, saurin warkar da busasshen busassun turmi na gida zai ragu sosai, kuma za a sami tsagewa saboda lokutan warkewa daban-daban. Don injin da aka fesa turmi tare da ginin injina, saboda ɗan gajeren lokacin haɗuwa, buƙatun don lafiya ya fi girma.

Lalacewar MC kuma yana shafar riƙon ruwa. Gabaɗaya magana, ga methyl cellulose ethers tare da danko iri ɗaya amma lafiya daban-daban, a ƙarƙashin adadin ƙari iri ɗaya, mafi kyawun mafi kyawun mafi kyawun tasirin riƙewar ruwa.

Riƙewar ruwa na MC kuma yana da alaƙa da yawan zafin jiki da ake amfani da shi, kuma riƙewar ruwa na methyl cellulose ether yana raguwa tare da haɓakar zafin jiki. Aiwatar a kan zafi substrates karkashin high zafin jiki yanayi don hanzarta curing na siminti da hardening na busassun foda turmi. Rage yawan adadin ruwa yana haifar da tasiri na iya aiki da juriya, kuma yana da mahimmanci don rage tasirin yanayin zafi a ƙarƙashin wannan yanayin.

Ko da yake methyl hydroxyethyl cellulose ether additives a halin yanzu ana la'akari da su a kan gaba wajen ci gaban fasaha, dogaro da zafin jiki har yanzu zai haifar da raunana aikin busassun busassun turmi. Ta hanyar wasu jiyya na musamman akan MC, irin su ƙara yawan digiri na etherification, da dai sauransu, ana iya kiyaye tasirin ruwa a cikin zafin jiki mafi girma, don haka zai iya samar da mafi kyawun aiki a ƙarƙashin yanayi mai tsanani.
