Kooxda Membrane Rui ee la shaqeeya Toray ee Horumarinta RO Membrane

2015, shirkadeena Membrane Rui Group iyo Shirkadda Toray ee Japan waxay saxiixday heshiis iskaashi, labada dhinac waxay fulin doonaan iskaashi qoto dheer oo xagga tignoolajiyada, wax soo saarka iyo iibinta xuubka osmosis-ka. Xafiiskayaga Shanghai ayaa ka qayb galay xafladda saxiixa. Ka dib, waxaan qaadnay wakiilka Japan si uu u booqdo warshadeena soo saarista xuubabka osmosis ee Yancheng, Gobolka Jiangsu, oo ay ka shaqeeyaan ilaa 100 shaqaale ah, aad buuna ugu qanacsanaa warshadeena.

"Aad ayaan ula dhacsanahay shaqaalaha warshadan, waa dadaal badan, xirfadlayaal ah, waxayna soo saaraan xuubka osmosis tayo sare leh, aad ayaan ugu faraxsanahay inaan wadashaqeyntan la gaaro MR Group."

Habka wax soo saarka ee xuubka osmosis-ka (xuubka RO) wuxuu ku lug leeyahay tillaabooyin jilicsan oo badan, oo ay ku jiraan xiriiriyeyaasha muhiimka ah sida diyaarinta xuubka saldhigga, polymerization interface, iyo daaweynta ka dib. 1. Diyaarinta filimka saldhigga ah (lakabka taageerada) iyo xulashada alaabta: Qalabka polymer-ka ee daloolka leh sida polysulfone (PS) iyo polyethersulfone (PES) ayaa badanaa la isticmaalaa. Habka beddelka wejiga: Polymer-ka waxa lagu milmaa dareere (sida DMF), oo lagu dahaadhay filim khafiif ah oo la dhex galiyay wax aan milmaynayn (sida biyaha) si loo sameeyo qaab-dhismeed dalool ah iyada oo loo marayo kala-saarista wejiga. Shuruudaha: Filimku wuxuu u baahan yahay inuu lahaado porosity sare, cabbir dalool lebbisan (qiyaastii 20-50nm) iyo xoog farsamo oo wanaagsan.2. polymerization interfacial (samaynta lakabka firfircoon), uur leh oo leh xal aqueous: filimka salka waxaa lagu rusheeyaa xal aqueous ka kooban polyamines (sida m-phenylenediamine, MPD) si ay u adsorb monomers. Xalinta wajiga saliidda ee impregnated: dib-u-cusbooneysiinta dareeraha organic (n-hexane) oo ay ku jiraan chloride acid (sida trimelligotricarboxyl chloride, TMC), falcelinta polycondensation ayaa dhacda. Natiijada falcelinta: Polyamide (PA) lakab firfircoon (qiyaastii 100-200 nm) ayaa la sameeyay, oo leh heerka sare ee heerka biyaha 3. Habka daawaynta ka dib, nadiifinta: ka saar monomers haraaga ah iyo alaabada. Qalajinta: Xakamaynta qoyaanka si aad uga fogaato hoos u dhaca waxqabadka xuubka. Dahaarka shaqaynaya: Xuubabka qaarkood waxay u baahan yihiin in lagu dahaadho lakab ilaalin ah (tusaale, alkolada polyvinyl) si loo hagaajiyo ka-hortagga wasakhda. 4. Isku duub walxaha xuubabka, duub filimka la dhammeeyey iyo shabagga weecinta, shaandhaynta iyo walxaha kale ee ku dheji curiyeyaasha wareegyada oo ku shub weelasha cadaadiska.

Waqtigan xaadirka ah, shirkadeena waxay leedahay noocyo kala duwan oo ah xuubka osmosis xuubka, oo ay ku jiraan cadaadiska hooseeya, cadaadiska sare iyo nadiifinta biyaha badda, wasakhowga ka hortagga iyo wixii la mid ah, si loo daboolo dhammaan xaaladaha codsiga.
