1. Matsalolin da aka saba fuskanta a cikin foda na putty
Busarwa cikin sauri ya faru ne saboda yawan sinadarin calcium da aka ƙara a toka (ya yi yawa sosai, ana iya rage yawan sinadarin calcium da aka yi amfani da shi a cikin tsarin putty yadda ya kamata) yana da alaƙa da yawan riƙe ruwa na zare, kuma yana da alaƙa da bushewar bango.
Barewa da lanƙwasawa suna da alaƙa da yawan riƙe ruwa, wanda ke da sauƙin faruwa lokacin da ɗanko na cellulose ya yi ƙasa ko kuma adadin ƙarawa ya yi ƙasa.
Cire foda na foda na bango na ciki yana da alaƙa da adadin foda na ash da aka ƙara (adadin foda na ash a cikin dabarar putty ya yi ƙanƙanta ko kuma tsarkin foda na ash ya yi ƙasa sosai, kuma ya kamata a ƙara adadin foda na ash a cikin dabarar foda na putty yadda ya kamata). A lokaci guda, yana kuma da alaƙa da adadin da ingancin cellulose, wanda ke nuna ƙimar riƙe ruwa na samfurin. Yawan riƙe ruwa yana da ƙasa, kuma lokacin da foda na ash (calcium oxide a cikin foda na ash ba a canza shi gaba ɗaya zuwa calcium hydroxide) bai isa ba. wanda ya haifar.
Kumfa yana da alaƙa da bushewar danshi da kuma faɗin bangon, kuma yana da alaƙa da ginin.
Bayyanar maƙallan yana da alaƙa da cellulose, wanda ke da mummunan halayen samar da fim. A lokaci guda, ƙazanta a cikin cellulose yana amsawa kaɗan da sinadarin ash calcium. Idan amsawar ta yi tsanani, foda putty zai bayyana a cikin yanayin ragowar wake curd. 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 samfuran kamar carboxymethyl da aka haɗa da cellulose.
Raƙuman ruwa da ramukan rami sun bayyana. Wannan a bayyane yake yana da alaƙa da matsin lamba a saman ruwa na maganin ruwa na hydroxypropyl methylcellulose. Jinkirin ruwan da ke kan teburin ruwa na maganin ruwa na hydroxyethyl ba a bayyane yake ba. Zai yi kyau a yi maganin ƙarshe.
Bayan putty ya bushe, yana da sauƙin fashewa ya koma rawaya. Wannan yana da alaƙa da ƙara yawan foda na ash-calcium. Idan aka ƙara yawan foda na ash-calcium da yawa, taurin foda na putty zai ƙaru bayan bushewa. Idan foda na putty ba shi da sassauci, zai fashe cikin sauƙi, musamman lokacin da aka fuskanci ƙarfin waje. Hakanan yana da alaƙa da yawan sinadarin calcium oxide a cikin foda na ash.
2. Me yasa foda na putty ke yin siriri bayan an ƙara ruwa?
Ana amfani da cellulose a matsayin mai kauri da kuma mai riƙe ruwa a cikin putty. Saboda thixotropy na cellulose kanta, ƙara cellulose a cikin putty foda shi ma yana haifar da thixotropy bayan ƙara ruwa a cikin putty. Wannan thixotropy yana faruwa ne ta hanyar lalata tsarin haɗin da aka haɗa na abubuwan da ke cikin putty foda. Wannan tsari yana tasowa a lokacin hutawa kuma yana rushewa a ƙarƙashin damuwa. Wato, viscosity yana raguwa yayin motsawa, kuma viscosity yana dawowa lokacin tsayawa cak.
3. Menene dalilin da yasa putty yake da nauyi sosai a tsarin gogewa?
A wannan yanayin, dankowar cellulose da ake amfani da ita gabaɗaya ya yi yawa. Wasu masana'antun suna amfani da cellulose 200,000 don yin putty. Putty da aka samar ta wannan hanyar yana da danko mai yawa, don haka yana jin nauyi lokacin gogewa. Adadin putty da aka ba da shawarar don bangon ciki shine kilogiram 3-5, kuma danko shine 80,000-100,000.
4. Me yasa cellulose ɗin viscosity iri ɗaya yake jin bambanci a lokacin hunturu da lokacin rani?
Saboda yanayin zafi na samfurin, ɗanɗanon putty da turmi zai ragu a hankali tare da ƙaruwar zafin jiki. Lokacin da zafin ya wuce zafin gel na samfurin, samfurin zai fito daga ruwa kuma ya rasa ɗanɗanon sa. Zafin ɗakin a lokacin rani gabaɗaya yana sama da digiri 30, wanda ya bambanta da zafin hunturu, don haka ɗanɗanon ya yi ƙasa. Ana ba da shawarar zaɓar samfurin da ke da ɗanɗanon sa mafi girma lokacin amfani da samfurin a lokacin rani, ko don ƙara yawan cellulose, da kuma zaɓar samfurin da ke da zafin gel mafi girma. Yi ƙoƙarin kada a yi amfani da methyl cellulose a lokacin rani. Zafin gel ɗin yana tsakanin digiri 55, idan zafin ya ɗan yi sama da haka, ɗanɗanon sa zai yi tasiri sosai.
