6. Adana, Rayuwar Rayuwa, da Tsaro
Yin watsi da yanayin ajiya shine hanya mafi sauri don lalata ganga mai tsada na foda.
Mataki 6.1: Iyakar zafi. Takardar bayanan za ta bayyana 'Ajiye a cikin sanyi, bushe wuri’ kuma sau da yawa matsakaicin zafin jiki (misali, 30°C ko 40°C). Kada a adana foda na RDP a cikin hasken rana kai tsaye ko kusa da tanderu. Babban zafin jiki na iya haifar da samuwar fim wanda bai kai ba a cikin jakar.
Mataki 6.2: Danshi shine abokan gaba. Foda shine hygroscopic. Takardar bayanan za ta yi gargaɗi game da kiyaye ta. Budaddiyar jakar da aka bari a cikin yanayi mai ɗanɗano za ta dunkule. Da zarar ya dunkule, rarrabuwar sa ya ragu sosai.
Mataki 6.3: Rayuwar rayuwa. Yawancin masana'antun garanti 6 ku 12 watanni daga ranar da aka yi. Ranar ‘Manufacturing’ ko 'Mafi Kyau Kafin’ layi akan takardar bayanan abokin ku ne. Juya hannun jarinku. Tsohuwar RDP na iya aiki har yanzu, amma aikinsa na iya ragewa.
Mataki 6.4: Tsaro na farko. Kowane takardar bayanan fasaha na masana'anta na RDP ya kamata ya yi la'akari da Tabbataccen Bayanan Tsaro na Kayan aiki (MSDS). Kurar polymer mai kyau yana da ban haushi kuma yana iya zama haɗarin fashewar ƙura. Yi amfani da abin rufe fuska koyaushe kuma tabbatar da samun iska. Takardar bayanan za ta bayyana PPE da ake bukata (Kayan Kariyar Keɓaɓɓen).
7. Daidaituwa: Yin Yana Aiki Tare da Sauran Sinadaran Ku
RDP ba ya aiki shi kaɗai. Yana hulɗa da siminti, masu cikawa, da sauran admixtures, musamman cellulose ethers (HPMC, HEMC).
Mataki 7.1: Daidaituwar siminti. Yawancin RDPs sun dace da siminti na Portland na yau da kullun (OPC), farin siminti, da siminti aluminate. Duk da haka, idan kun yi amfani da siminti-alumina ko takamaiman pozzolans, duba takardar bayanan. Wasu polymers suna yin hydrolyze a cikin yanayin pH masu girma.
Mataki 7.2: Yin hulɗa tare da ethers cellulose. Cellulose ethers inganta ruwa rike. RDP yana inganta mannewa. Suna aiki tare, amma kuma suna gasar neman ruwa. Idan tsarin ku yana jin manne ko 'gummy,’ Matsakaicin RDP ɗin ku na iya yin girma da yawa dangane da HPMC ɗin ku. Takardar bayanan ba za ta gaya muku girke-girke ba, amma zai ba ku kewayon ballpark don tsarin da suka dace.
Mataki na gaba: Kwatanta, Gwaji, kuma Nasara
Yanzu kuna da ilimin karanta kowane takaddar bayanan fasaha na RDP foda tare da amincewa. Kada ku karanta takardar masana'anta ɗaya kawai. Tattara uku ko hudu. Sanya su gefe-da-gefe. Kwatanta Tg, Farashin MFFT, adhesion dabi'u, da yanayin ajiya.
Yi gwaji mai sauƙi. Yi amfani da daidaitaccen girke-girke na turmi. Canza RDP kawai. Gwada iya aiki da hannu. Gwada manne akan tayal. Dubi bambanci da kanku. Takardar bayanan taswira ce. Kai ne mai binciken. Amince hannuwanku da idanunku, jagorancin wannan takarda.
