1. Matsaloli na yau da kullum a cikin putty foda
Yana bushewa da sauri:
Babban dalili shi ne, adadin ash calcium foda da aka saka (ya yi yawa, adadin ash calcium foda da ake amfani da shi a cikin tsari na putty za a iya rage shi yadda ya kamata) yana da alaka da yawan ajiyar ruwa na fiber, kuma yana da alaka da bushewa. na bango.
Barewa da mirgina:
Yana da alaƙa da ƙimar riƙewar ruwa, kuma ƙananan ƙarancin cellulose yana da haɗari ga wannan yanayin ko adadin ƙarawa kaɗan ne.
De-powdering na ciki bango putty foda:
Adadin ash calcium powder da aka saka (yawan ash calcium powder a cikin dabarar da ake sakawa ya yi kadan ko kuma tsarkin ash calcium powder yayi kasa sosai, sannan a kara adadin ash calcium a cikin foda mai sanyawa a kara yadda ya kamata) , kuma yana da alaƙa da adadin cellulose da kuma ingancin da ke da alaƙa, wanda ke nunawa a cikin adadin ruwa na samfurin.Adadin ajiyar ruwa yana da ƙasa, kuma ash calcium foda (calcium oxide a cikin ash calcium foda ba a cika juyowa zuwa calcium hydroxide don hydration) bai isa lokaci ba, wanda aka haifar.
Kumfa:
Busasshen zafi na bango yana da alaƙa da shimfidar wuri, kuma yana da alaƙa da ginin.
Wani ma'ana yana bayyana:
Yana da alaƙa da cellulose, kayan aikin fim ɗinsa ba su da kyau, kuma a lokaci guda, ƙazanta a cikin cellulose suna amsa dan kadan tare da ash ash.Idan abin ya kasance mai tsanani, foda mai sanyawa zai bayyana a cikin yanayin ragowar wake na wake.Ba za a iya sanya shi a bango ba, kuma ba shi da ƙarfin haɗin kai a lokaci guda.Bugu da ƙari, wannan yanayin yana faruwa tare da samfurori irin su carboxymethyl gauraye da cellulose.
Bayan putty ta bushe, yana da sauƙi a fashe kuma ya juya rawaya:
Yana da alaƙa da ƙari mai yawa na ash-calcium foda.Idan an ƙara adadin ash-calcium foda da yawa, taurin foda zai karu bayan bushewa.Idan putty foda ba shi da sassauƙa, zai zama da sauƙi a fashe, musamman ma lokacin da aka yi shi da ƙarfin waje.Hakanan yana da alaƙa da babban abun ciki na calcium oxide a cikin ash calcium foda.
2. Me yasa foda ya zama bakin ciki bayan ƙara ruwa?
Ana amfani da Cellulose azaman mai kauri da mai riƙe da ruwa akan 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 da aka haɗa da 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.
3. Menene dalilin da ya sa putty yayi nauyi sosai a cikin tsari na scraping?
A wannan yanayin, danko na 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.
4. Me yasa cellulose danko iri ɗaya ke jin daban a lokacin hunturu da bazara?
Saboda thermal gelation na samfurin, danko na putty da turmi za su 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.An ba da shawarar cewa a lokacin rani, yi ƙoƙarin zaɓar samfurin tare da ɗanko mafi girma lokacin amfani da samfurin, ko ƙara yawan adadin cellulose.
