Polypropyleneglycol CAS: 25322-69-4

Kapangidwe kake kosiyanasiyana ka polypropyleneglycol kamapangitsa kuti ikhale chinthu chofunikira kwambiri m'magawo ambiri amafakitale. Mumakampani opanga magalimoto, imagwiritsidwa ntchito ngati chinthu chofunikira kwambiri popanga mabuleki, madzi amadzimadzi, ndi madzi otumizira chifukwa cha kukhazikika kwake kwa kutentha ndi okosijeni, mphamvu zopaka mafuta, komanso magwiridwe antchito otsika kutentha, zomwe zimathandiza kuti machitidwe a magalimoto azikhala bwino komanso otetezeka. Mu gawo la mankhwala, polypropyleneglycol imagwiritsidwa ntchito ngati chowonjezera mu mankhwala opangira kuti iwonjezere kusungunuka, kupezeka kwa bioavailability, komanso kukhazikika kwa zosakaniza zogwira ntchito zamankhwala. Kugwirizana kwake ndi mankhwala osiyanasiyana kumapangitsa kuti ikhale chinthu chofunikira kwambiri mu kukonzekera mankhwala, kuthandizira kupanga mankhwala ogwira mtima m'malo osiyanasiyana ochiritsira. Kuphatikiza apo, polima iyi imagwiritsidwa ntchito kwambiri popanga zinthu zosamalira thupi monga zodzoladzola, zinthu zosamalira khungu, ndi njira zosamalira tsitsi. Kapangidwe kake kofewa komanso kowongolera khungu kumathandiza kuti zinthu zosamalira thupi zikhale bwino, zomwe zimapangitsa kuti mafuta azisungunuka komanso azisalala pa ntchito zosamalira khungu ndi tsitsi. Kuphatikiza apo, polypropyleneglycol imagwira ntchito ngati chinthu chofunikira kwambiri pakupanga mafakitale, kuphatikizapo kupanga polyurethane, komwe ntchito yake ngati reactive intermediate imathandizira kupanga ma polyurethane polymers ndi thovu. Kugwiritsa ntchito kwake mu urethane elastomers ndi zokutira kukuwonetsa kufunika kwake popanga zipangizo zogwira ntchito kwambiri zamafakitale ndi zamalonda. Kuphatikiza apo, pankhani ya mafuta ndi madzi ogwirira ntchito zachitsulo, polypropyleneglycol imagwira ntchito ngati madzi oyambira opangidwa, kupereka mafuta abwino kwambiri komanso kukhazikika kwa kutentha m'mafakitale osiyanasiyana. Kugwiritsa ntchito kwake pantchito zogwirira ntchito zachitsulo, mafuta a zida, ndi mafuta ophikira mafakitale kumathandizira kugwira ntchito bwino komanso kukhala ndi moyo wautali kwa makina ndi zida. Ponseponse, kugwiritsa ntchito kosiyanasiyana kwa polypropyleneglycol m'magalimoto, mankhwala, chisamaliro chaumwini, njira zamafakitale, ndi kupanga zinthu kukuwonetsa kufunika kwake ngati polima wosinthasintha komanso wofunikira, zomwe zimathandiza pakupanga zinthu ndi zipangizo zogwira ntchito kwambiri m'mafakitale osiyanasiyana.
