Matsayin hydroxypropyl methylcellulose a cikin putty

Daga kauri, riƙe ruwa da kuma gina ayyuka uku.

Kauri: Ana iya ƙara kauri a cellulose don dakatarwa, kiyaye maganin daidai gwargwado kuma daidai, da kuma tsayayya da lanƙwasawa. Riƙe ruwa: Sanya foda putty ya bushe a hankali, kuma yana taimakawa wajen daidaita sinadarin toka a ƙarƙashin aikin ruwa. Ginawa: Cellulose yana da tasirin shafawa, wanda zai iya sa foda putty ya sami aiki mai kyau. Hydroxypropyl methylcellulose baya shiga cikin kowane irin amsawar sinadarai kuma yana taka rawa kawai. Ana ƙara foda putty da ruwa don haɗa bango, wanda shine amsawar sinadarai, saboda akwai ƙirƙirar sabon abu na calcium carbonate. Babban abubuwan da ke cikin foda calcium toka sune: cakuda calcium hydroxide Ca(OH)2, calcium oxide CaO da ƙaramin adadin calcium carbonate CaCO3. Calcium toka yana samar da calcium carbonate ƙarƙashin aikin CO2 a cikin ruwa da iska, yayin da hydroxypropyl methyl Cellulose kawai yana riƙe ruwa kuma yana taimakawa mafi kyawun amsawar sinadarin toka, wanda da kansa baya shiga cikin kowane amsawa.

Da farko za mu yi nazarin dalilan da suka sa aka samu faɗuwar foda na putty daga albarkatun ƙasa na putty: foda na ash calcium, hydroxypropyl methylcellulose, foda na ash calcium mai nauyi, foda na ash calcium na ruwa

1. A zahiri, domin hanzarta ruɓewar sinadaran, sau da yawa ana ƙara zafin calcination zuwa 1000-1100 °C. Saboda girman kayan ƙasa na dutse ko kuma rashin daidaiton rarrabawar zafin da ke cikin murhun yayin calcination, lemun tsami galibi yana ɗauke da lemun tsami da aka ƙone da wuta mai yawa. Calcium carbonate da ke cikin lemun tsami ba ya ruɓewa gaba ɗaya, kuma ba shi da ƙarfin haɗin kai yayin amfani, wanda ba zai iya samar da isasshen ƙarfi ga putty ba, wanda ke haifar da cire foda wanda rashin ƙarfi da ƙarfin putty ke haifarwa.

2. Yawan sinadarin calcium hydroxide a cikin foda na toka, haka nan kuma yawan sinadarin putty da ake samarwa ya fi tauri. Akasin haka, ƙarancin sinadarin calcium hydroxide a cikin foda na toka, haka nan kuma tauri na putty ya fi muni a wurin samarwa, wanda hakan ke haifar da matsalar cire foda da kuma cire foda.

3. Ana haɗa garin calcium na toka da babban adadin foda mai kauri, wanda hakan ke sa sinadarin calcium na toka ya yi ƙasa sosai don samar da isasshen tauri da ƙarfi ga putty, wanda hakan ke sa putty ya zubar da foda. Babban aikin foda na putty shine riƙe ruwa, samar da isasshen ruwa don taurare foda na toka, da kuma tabbatar da isasshen tasirin taurarewa. Idan akwai matsala da ingancin hydroxypropyl methylcellulose ko kuma ingantaccen abun ciki ya yi ƙasa, ba za a iya samar da isasshen danshi ba, wanda zai sa taurarewar ta yi ƙasa kuma ya sa putty ya zubar da foda.

Daga abin da ke sama, ana iya gano cewa ingancin hydroxypropyl methylcellulose ba shi da kyau kuma ba zai iya cimma wani tasiri ba, kuma foda putty zai faɗi. Babban dalilin shine launin toka mai nauyi na calcium.
