1. Me yasa foda ya zama bakin ciki bayan ƙara ruwa?
Ana amfani da ether cellulose azaman mai kauri da mai riƙe da ruwa a cikin putty.Saboda thixotropy na cellulose kanta, ƙari na cellulose a cikin putty foda kuma yana haifar da thixotropy bayan ƙara ruwa zuwa putty.Wannan thixotropy yana haifar da lalacewa ta hanyar lalata tsarin haɗin kai na abubuwan da ke cikin foda.Wannan tsarin yana tasowa a lokacin hutawa kuma yana rushewa a ƙarƙashin damuwa.Wato danko yana raguwa a karkashin motsawa, kuma danko yana farfadowa lokacin da yake tsaye.
2. Menene dalilin da ya sa putty yayi nauyi sosai a cikin tsarin scraping?
A wannan yanayin, dankon cellulose gabaɗaya da ake amfani da shi ya yi yawa.Wasu masana'antun suna amfani da cellulose 200,000 don yin putty.Kayan da aka samar ta wannan hanya yana da babban danko, don haka yana jin nauyi lokacin da ake gogewa.Adadin da aka ba da shawarar putty don ganuwar ciki shine 3-5 kg, kuma danko shine 80,000-100,000.
3. Me yasa putty da turmi da aka yi da cellulose tare da danko iri ɗaya suna jin daban-daban a cikin hunturu da bazara?
Saboda thermal gelation na samfurin, dankon samfurin zai ragu a hankali tare da karuwar zafin jiki.Lokacin da zafin jiki ya zarce zafin gel na samfurin, samfurin zai haɗe daga ruwa kuma ya rasa danko.Yanayin zafin jiki a lokacin rani gabaɗaya yana sama da digiri 30, wanda ya bambanta da yanayin zafi a lokacin hunturu, don haka danko yana ƙasa.Ana bada shawara don zaɓar samfurin tare da danko mafi girma lokacin amfani da samfurin a lokacin rani, ko ƙara yawan adadin cellulose, kuma zaɓi samfurin tare da zafin jiki mafi girma.
