Methoxypolyethylene Glycols CAS 9004-74-4

Polyethylene glycol monomethyl ether ndi chinthu chochokera ku polyethylene glycol. Sichisungunuka m'madzi, ethanol ndi zinthu zambiri zosungunuka zachilengedwe. Sichisinthasintha kwambiri kuposa glycerol, chili ndi mphamvu zokhazikika zamakemikolo, sichimasungunuka mosavuta ndi kuwonongedwa, ndipo chimakhala ndi mphamvu yolimba ya hydrophilicity. Chili ndi mphamvu yochepa ya nthunzi ndipo chimakhala chokhazikika kutentha. Chimagwiritsidwa ntchito ngati chokhuthala komanso mafuta mumakampani osindikizira ndi kupaka utoto ndi makampani opanga mankhwala a tsiku ndi tsiku. Mumakampani opanga zida zomangira, chimagwiritsidwa ntchito ngati zopangira zochepetsera madzi a simenti ndi zinthu zolimbitsa. Polycarboxylic acid yochepetsera madzi yopangidwa pogwiritsa ntchito zinthuzi ili ndi mphamvu yayikulu yosunga kufalikira kwa tinthu ta simenti, zomwe zimapangitsa kuti mankhwalawa akhale ndi ubwino wochepa, kuchepetsa madzi kwambiri, kulimbitsa bwino, kulimba, kusakhala ndi dzimbiri kwa zitsulo komanso kusamala chilengedwe. Chingagwiritsidwe ntchito mu konkriti yogulitsa yogwira ntchito bwino, yamphamvu kwambiri (C60 kapena kupitirira apo) yosakanikirana pamalopo komanso yoyendera mtunda wautali.
