3. Dangantaka tsakanin HPMC da Pursization
A matsayin wakili mai kauri da mai riƙe da ruwa, aikin hpmc a Putty foda yana da tasiri kai tsaye kan ingancin Putty. Tasirin HPMC akan foda yafi bayyana a cikin wadannan fannoni:
(1) rinjayar riƙewar ruwa
Faɗakarwa na Putty foda yana da alaƙa da saurin ruwa na ruwa a cikin putty. Idan adadin HPMC bai isa ba, da Putty foda ya rasa ruwa da sauri yayin aiwatar da bushewa kuma ya kasa cikakken ƙarfafa. Dukiyar riƙe da ruwa ta HPMC tana taimakawa Putty kula da danshi da ta dace yayin aiwatar da bushewa, yana ba da puty don sannu a hankali kuma yana hana foda ya haifar da asarar ruwa. Saboda haka, Ruwa na Ruwa na HPMC yana da mahimmanci don rage foda.
(2) tasirin tasirin thickening
HPMC na iya ƙara daidaito na Perty foda, saboda sanya Putty za a iya ƙara haɗawa da substrate. Idan ingancin hpmc ba shi da kyau ko kuma ana amfani da shi da kyau, zai iya shafar da foda da sauri, wanda zai iya haifar da foda da sauri, don haka haifar da foda. Bugu da kari, wuce gona da iri na HPMC zai kuma haifar da saman foda na pavy ya zama mai laushi bayan gini, da ya shafi tasirin tare da hadewa kuma yana haifar da foda a saman.
(3) daidaito tare da wasu kayan
A cikin Putty foda, ana amfani da HPMC a hade tare da sauran masu sumunti na (kamar ciminti, gypsum) da masu yawa, talcum foda). Adadin HPMC da aka yi amfani da su da kuma saiti tare da wasu kayan suna da babban tasiri a kan aikin da ke putty. Tsarin mara hankali na iya haifar da isasshen ƙarfin Putty foda kuma a ƙarshe yana haifar da foda. Amfani da HPMC mai ma'ana na iya taimakawa inganta aikin haɗin gwiwar da ƙarfin Putty kuma ku rage matsalar foda ta hanyar karancin abubuwa marasa kyau.
4. Matsalolin ingancin HPMC suna haifar da foda
Baya ga adadin HPMC da aka yi amfani da shi, ingancin HPMC kanta na iya shafar wasan kwaikwayon Putty foda. Idan ingancin HPMC ba har zuwa matsayi ba, kamar ƙarancin tsarkakawar selulose, zai iya kai tsaye kai tsaye ciyawar foda, kuma ƙara haɗarin foda. Rashin HPMC ba kawai da wahala kawai don samar da ingantaccen riƙewar ruwa da tasirin ruwa, amma may yana iya haifar da fashewa, fldering da sauran matsaloli a lokacin bushewa na putty. Sabili da haka, zabar hpmc mai inganci yana da mahimmanci don guje wa matsalolin foda.
5. Tasirin sauran dalilai akan foda
Kodayake HPMC tana taka muhimmiyar rawa a cikin Foreder foda, fldering yawanci shine sakamakon hade da tasirin abubuwan da yawa. Wadannan dalilai na iya haifar da foda:
Yanayin yanayin: idan yawan zafin jiki da zafi na ginin ginin sun yi yawa ko ma yakai, zai shafi saurin bushewa da tasirin bushewa na ƙarshe.
Rashin Subrate magani: Idan substrate ba tsabta ko farfajiya na subesrate yana ɗaukar ruwa da yawa, zai shafi tasirin foda na putty foda.
Abin sani na rashin tsari na abinci: Ana amfani da kadan ko kadan HPMC, da kuma yawan kayan cumety ba su da isasshen adon, wanda zai haifar da foda.
Faɗin foda na foda na pyty foda yana da alaƙa da amfani da HPMC. Babban aikin hpmc a cikin foda shine riƙewar ruwa da thickening. Amfani da amfani zai iya hana abin da ya faru na foda. Koyaya, abin da ya faru na foda ya dogara ne kawai akan HPMC, har ma akan dalilai kamar dabaru na Perty foda, substrate magani, da kuma yankin gini. Don kauce wa matsalar foda, yana kuma mahimmanci don zaɓar HPMC mai inganci, ƙirar dabara mai ma'ana, fasahar kimiyya da ingantaccen yanayi.
