2. Kauri na Rufi
3. Ingancin Rufi
1. Ingancin Walda
Ingancin rufin gyaran ruwa ya dogara ne da siffar geometric na dinkin walda. Idan dinkin walda yana da wuraren fashewa, fitar da iska mai tsanani, ko kuma wani wuri mai kauri, rufin ruwa ba zai iya rufe shi gaba ɗaya ba. Bugu da ƙari, kauri na dinkin walda yana shafar tasirin rufin; gabaɗaya, kauri na dinkin walda ya kamata ya zama ƙasa da kauri na farantin sau 1.5. Ga ƙarfe mai sanyi ko ƙarfe mai tauri, kauri na dinkin walda ya ninka kauri na farantin sau 1.5 zuwa 1.8.
Dinkin walda da aka yi ba tare da kariyar nitrogen ba na iya samun ƙarancin mannewa na murfin gyara saboda yawan yadudduka na oxide, wanda ke haifar da fashewar shafi yayin ayyukan da ke gaba kamar flanging, necking, da beads, wanda ke shafar ingancin murfin gyara.
Rufin foda, saboda isasshen kauri, zai iya magance matsalolin fallasa ƙarfe da lahani na walda ke haifarwa, yana ba da kyakkyawan kariya ga dinkin walda.
2. Kumfa
Tsarin sinadaran da ba su dace ba a cikin gyaran ruwa na iya shafar ingancin murfin. Idan murfin ruwa ya ƙunshi ƙarin sinadaran da ba su da zafi sosai, ko kuma idan zafin ya tashi da sauri yayin yin burodi, ko kuma idan zafin haɗin walda ya yi yawa, yawan sinadaran da ke narkewa yana ƙafewa yayin yin burodi, yana barin igiyoyin kumfa ko ƙananan ramuka a cikin murfin, yana rage rufewa da tasirin kariya akan ɗinkin walda.
4. Yin burodi da kuma warkarwa
1. Tsarin Gyaran Rufin Gyara
Za a iya raba yin burodi da kuma tsaftace murfin ruwa zuwa matakai kamar haka: matakin farko na shafa shi ya jika wurin da aka yi wa walda da wuraren da babu komai (kimanin daƙiƙa 1-2), sannan a biyo baya da fitar da sinadarin narkewa don samar da gel (ya kamata a kammala shi cikin daƙiƙa 3-5; in ba haka ba, murfin zai gudana daga wurin da aka yi wa walda), sannan a ƙarshe a yi amfani da polymerization. Dole ne murfin ya sami isasshen zafi, wanda hakan ke shafar kauri da aikin gyaran murfin. Kamar yadda aka ambata a baya, saurin ƙaruwar zafin jiki yayin yin burodi na iya haifar da kumfa cikin sauƙi, yayin da hauhawar zafin jiki a hankali na iya haifar da rashin isasshen warkarwa saboda ɗan gajeren lokacin kula da zafin jiki.
Rufi daban-daban suna da lokutan kololuwa daban-daban yayin yin burodi; rufi na epoxy phenolic yana buƙatar lokaci mai tsawo fiye da rufi na organosol, ma'ana suna buƙatar ƙarin zafi don yin burodi.
Ga shafa foda, shafa thermoplastic kawai yana narkewa don samar da fim yayin yin burodi ba tare da polymerization ba, yayin da shafa thermosetting ke yin ƙarin polymerization bayan an fara polymerization da narkewa don haɗuwa zuwa cikin mahaɗan ƙwayoyin halitta masu yawa. Saboda haka, zafin yin burodi yana da alaƙa da aikin shafa gyara.
2. Tasirin Digirin Magancewa akan Aikin Shafawa
Gyaran rufin zai iya nuna halayensa ne kawai idan an gasa shi gaba ɗaya kuma an warke. Rashin isasshen yin burodi yana haifar da ƙananan ramuka da rashin iya sarrafawa; misali, rufin foda na thermoplastic da ba a gasa sosai ba na iya ƙunƙulewa yayin ƙunƙun. Yin burodi da yawa yana shafar mannewa; misali, rufin epoxy phenolic da aka gasa da yawa yana zama mai rauni kuma yana iya fashewa yayin ƙunƙun, ƙunƙun wuya, da ƙunƙun beads. Bugu da ƙari, isasshen sanyaya bayan yin burodi yana da mahimmanci don aikin murfin gyara. Misali, idan murfin foda na thermoplastic bai yi sanyi da sauri zuwa zafin ɗaki bayan yin burodi ba, murfin na iya fashewa yayin ƙunƙun. Ƙara na'urar sanyaya bayan tanda na iya hana matsalolin tsagewa a cikin murfin gyara yayin ƙunƙun.
A taƙaice, domin tabbatar da ingancin murfin gyara—watau, ƙarancin porosity da kuma ingantaccen sarrafawa—yana da matuƙar muhimmanci a kula da kauri da matakin wartsakewar murfin.
