Hanyar Gwaji Mai Inganci na Foda Mai Sake Rarrabawa ta Polymer
Gwajin inganci na foda polymer da za a iya sake wargazawa (RDP) yana da matuƙar muhimmanci don tabbatar da cewa ya cika ƙa'idodi da ƙayyadaddun bayanai da ake buƙata don aikace-aikace daban-daban, kamar kayan gini kamar manne tayal, turmi, da membranes masu hana ruwa shiga. Ga wasu hanyoyin gwajin inganci gama gari don foda polymer da za a iya sake wargazawa:
1.Binciken Girman Barbashi: Rarraba girman barbashi yana shafar aikin RDP kai tsaye dangane da warwatsewa, samuwar fim, da kuma halayen injiniya. Ana iya amfani da dabarun rarraba laser, sedimentation, ko microscopy don auna rarraba girman barbashi na RDP.
2.Yawan Yawa: Yawan yawa muhimmin siga ne wanda ke tasiri ga yadda ake sarrafa shi, jigilar sa, da kuma haɗa shi na RDP. Yawanci ana auna shi ta hanyar cike wani ƙaramin adadin RDP da aka sani a cikin akwati da kuma auna nauyinsa. Sannan ana ƙididdige yawan yawan ta hanyar raba nauyin da girman.
3.Abun Ciki Mai Kyau: Taurin abun ciki na RDP yana nufin kashi na polymer da ke cikin foda. Yawanci ana tantance shi ta hanyar busar da wani nau'in RDP da aka sani a wani takamaiman zafin jiki sannan a auna sauran nauyin. Ana ƙididdige abun ciki mai tauri bisa ga asarar nauyi yayin bushewa.
4.Zafin Canjin Gilashi (Tg): Tg na RDP alama ce ta kwanciyar hankalin zafi kuma tana tasiri ga yanayin ajiya da sarrafawa. Ana iya amfani da calorimetry na duba bambanci (DSC) ko kuma nazarin injiniya mai ƙarfi (DMA) don tantance Tg na RDP.
5.Danko na Rarraba RDP: Danko na watsawar RDP yana da matuƙar muhimmanci ga halayen aikace-aikacensa, kamar iya aiki, lokacin buɗewa, da juriyar sag. Ana iya auna shi ta amfani da na'urar aunawa ko rheometer a ƙarƙashin yanayin yankewa da aka sarrafa.
6.Samar da Fim da Mannewa: Ƙwarewar ƙirƙirar fim da ƙarfin mannewa na RDP suna da matuƙar muhimmanci ga aikin sa a kayan gini. Ana iya amfani da hanyoyi kamar gwajin ƙirƙirar fim, gwajin mannewa na barewa, da gwaje-gwajen tensile don kimanta waɗannan halaye.
7.Binciken Sinadaran da Aka Haɗa: Ana iya amfani da dabarun kamar Fourier-transform infrared spectroscopy (FTIR) ko nuclear magnetic resonance (NMR) spectroscopy don nazarin sinadaran da ke cikin RDP da kuma tabbatar da daidaito da tsarkinsa.
8.Gwajin Juriyar Ruwa: Ana amfani da RDP sau da yawa a aikace-aikace inda juriyar ruwa take da mahimmanci, kamar membranes masu hana ruwa shiga. Ana iya kimanta juriyar ruwa ta hanyar gudanar da gwaje-gwaje kamar gwaje-gwajen nutsewa cikin ruwa ko gwaje-gwajen watsa tururin ruwa akan kayan da ke ɗauke da RDP.
Waɗannan su ne kawai wasu daga cikin hanyoyin gwajin inganci da aka saba amfani da su don sake wargaza foda na polymer. Dangane da takamaiman buƙatun aikace-aikacen da ƙa'idodi/ƙa'idoji da ake da su, ƙarin gwaje-gwaje na iya zama dole don tabbatar da inganci da aikin samfuran RDP.
