hello sir, may I ask. I'm currently casting the membrane, but I'm having a problem. After I cast it and then put it in the coagulation bath, my membrane sticks to the glass plate. Is there a solution that I can do to prevent the membrane from sticking to the glass plate? thank you..
You should sink the casting membrane about 3 minute before you pick up your membrane. Did you let the membrane totally under coagulation bath in 3 minutes?
@@rahmatsunarya yes, i even sink the membrane more than 3 minutes because it was still sticking to the glass plate. anw i am using cellulose acetate and NMP solvent to make the membrane
Ye polysulfone membrane casting ha jo hmne vedio mn ki thi,apko polyamide membrane agar cast krni hai to thora sa procedure change hai uska ,non solvent induced phase sepation k through bht baareek fragile banegi
Hi, I am just wondering whether the way you cast will bring many pores into the menbrane or not.
Hello thank you for your comment. Surely, this method give us many pores. For make sure, I take SEM picture and there are many pores

Please tell me the detail composition your membrane solution at rahmatsunarya@gmail.com
@@rahmatsunarya i've emailed you, thank you so much for helping me
I just answered your email. Kindly check
hi sir how can we make this and what material use for this kindly share details with weight of material used in it for making
Made by 20% polysulfone and 80% NMP in 50 gram solution
@@rahmatsunarya sir still confused kindly explain simply and where i got these chemicals
10 gram PS mixed well in 40 gram NMP. Then you have a polymer solution. Now, the solution is casted like my video
@@rahmatsunarya thanks sir and can i learn from you to make a membrane
Sure. If you have some questuions again, let me know at rahmatsunarya@gmail.com
hi, plz make a video with a clear voice and sub title in English,and please make a video of a Thin film composite polyamide membrane.
Thank you for your comment. I am so sorry. If you need some help let me know. You can find at rahmatsunarya@gmail.com 🙏
