Akwai wata dangantaka tsakanin ingancin foda na putty foda da HPMC (hydroxypropyl methylcellulose), amma ayyuka da tasirin su biyu sun bambanta.
1. Haɗin kai da halayen foda na putty foda
Putty foda kayan gini ne da ake amfani da shi don daidaita bango, gyarawa da ado. Babban abubuwan da aka gyara sun haɗa da kayan tushe (kamar suminti, gypsum), masu cikawa (kamar calcium carbonate) da ƙari (irin su ether cellulose, wakili mai riƙe ruwa, da sauransu). The foda ingancin putty foda yafi yana nufin fineness, uniformity da kuma jin ta barbashi a lokacin gini. Wannan ingancin foda yana shafar abubuwa masu zuwa:
Girman barbashi na filler: Calcium carbonate yawanci ana amfani dashi azaman babban filler. Mafi kyawun barbashi na calcium carbonate, mafi kyawun ingancin foda na putty, kuma mafi kyawun laushi da santsi na bango bayan aikace-aikacen.
Nau'in kayan tushe: Alal misali, simintin siminti foda da gypsum-based putty foda za su sami nau'i daban-daban da halaye saboda nau'ikan kayan da aka yi amfani da su. Barbashi na siminti-tushen putty foda na iya zama m, yayin da na gypsum-tushen putty foda na iya zama mafi kyau.
Fasahar sarrafa kayan aiki: A cikin aiwatar da samar da foda, matakin niƙa da daidaiton dabara kuma zai shafi ingancin foda. Ingantacciyar fasahar sarrafa kayan aiki na iya samar da ƙoshin ƙoshin ƙoshin ƙoshi mai ɗaci.
2. Matsayin HPMC a cikin putty foda
HPMC, wato hydroxypropyl methylcellulose, ƙari ne na kowa a cikin foda. Yana da polymer mai narkewa da ruwa wanda galibi yana taka rawa na kauri, riƙe ruwa da haɓaka aikin gini. HPMC da kanta ba ta tasiri kai tsaye ga ƙarancin barbashi (watau ingancin foda) na putty foda, amma yana da babban tasiri na haɓakawa akan aikin ginin putty foda:
Tasirin riƙewar ruwa: Wani muhimmin aiki na HPMC shine riƙewar ruwa, wanda zai iya jinkirta zubar da ruwa a cikin foda a lokacin ginawa kuma ya hana ƙwayar ƙwayar cuta daga bushewa da wuri a lokacin gina bango. Wannan yana da tasiri mai kyau akan matakan bango da mannewa, musamman ma a cikin yanayin zafi da bushewa, riƙewar ruwa yana da mahimmanci.
Tasiri mai kauri: HPMC na iya ƙara danko na putty foda, don haka yana da daidaiton matsakaici da sauƙin gogewa bayan motsawa. Wannan sakamako yana taimakawa wajen sarrafa ruwa na putty foda yayin gini, yana rage yanayin faɗuwar tashi da foda, kuma yana iya haɓaka ƙarfin haɗin gwiwa, ta haka a kaikaice inganta jin daɗi yayin gini.
Inganta aikin gine-gine: Kasancewar HPMC na iya sanya foda mai sauƙin yin aiki yayin gini, jin daɗi, da gabatar da ƙarin yunifofi da sakamako mai laushi lokacin yin laushi. Ko da yake HPMC ba ya canza lafiyar jiki na ƙwayoyin foda na putty, yana inganta aikin aiki gaba ɗaya kuma yana sa jin foda ya zama mai laushi lokacin amfani da shi.
3. Tasirin kai tsaye na HPMC akan ingancin putty foda
Ko da yake HPMC ba kai tsaye canza barbashi size ko jiki fineness na putty foda, shi inganta gina sakamako na putty foda ta hanyar ruwa riƙewa, thickening, lubricity da sauran al'amurran, sa putty foda santsi da kuma sauki a yi aiki a lokacin da amfani. A yayin aiwatar da aikin, sa foda mai ɗauke da HPMC ya fi sauƙi don amfani da lebur, rage ɓarna da rashin daidaituwa, wanda ke sa masu amfani su ji cewa foda ya fi laushi.
Riƙewar ruwa na HPMC na iya hana raguwar raguwa a cikin busassun foda yayin aikin bushewa na bango, wanda kuma yana da tasiri mai kyau akan haɓaka haɓakar bangon gabaɗaya da santsi. Sabili da haka, daga hangen nesa na sakamako na bango na ƙarshe, HPMC yana da wani tasiri kai tsaye akan fineness na putty foda.
4. Dangantaka tsakanin sashi na HPMC da ingancin foda
Yawan adadin HPMC kuma yana buƙatar sarrafa shi da kyau. Yawancin lokaci, adadin HPMC a cikin foda mai ɗorewa yana da ƙananan ƙananan, kuma amfani da yawa zai haifar da matsalolin masu zuwa:
Over-thickening: Idan sashi na HPMC ya yi yawa, da putty foda na iya zama ma danko, sa shi da wuya a motsa, kuma yana iya ma haifar da matsaloli kamar foda asarar da surface m. Ba shi da sauƙi a yi amfani da lebur a lokacin gini, wanda zai shafi tasirin bango na ƙarshe kuma ya ba mutane jin daɗin foda.
Tsawaita lokacin bushewa: Sakamakon riƙewar ruwa na HPMC zai jinkirta lokacin bushewa na foda. Idan adadin ya yi yawa, bangon bazai bushe ba na dogon lokaci, wanda kuma ba shi da amfani ga ci gaban ginin.
Sabili da haka, adadin HPMC dole ne ya kasance a cikin kewayon da ya dace don taka rawa wajen inganta ingancin foda.
Ingantattun foda na putty an ƙaddara shi ne ta hanyar ingancin kayan tushe da filler, kazalika da tsarin samarwa da sauran dalilai. A matsayin ƙari a cikin sa foda, HPMC ba ta ƙayyade ingancin foda kai tsaye ba, amma yana da tasiri mai kyau kai tsaye a kan ingancin ingancin foda ta hanyar inganta riƙewar ruwa, daɗaɗɗa da kayan gini na putty foda. Ma'ana yin amfani da HPMC iya sa putty foda nuna mafi kyau ji da aikace-aikace sakamako a lokacin gina, rage yi lahani, kuma haka inganta overall flatness da fineness na bango.
