Na he maha nga iwi kaore e mohio ki te nuinga o te etery eterdroxypropyl. Ki ta ratau whakaaro he iti te rereketanga i waenga i te EterdroxyPropyl othher Eter me te māngaro noa, engari kaore. Ko te nui o te hydroxypropyl o te papaa o te maaka i whakamahia i roto i nga hua o te paru, a, ko te taapiri o te polar ka taea te whakatutuki i nga paanga kounga pai.
Hydroxypropyl Eter Ather (HPS) He paura pai e whiwhi ana ma te whakarereke i nga tipu taiao, ka tino whakaitihia, ka rewa - ka maroke. He rereke rawa atu i te māngaro noa, te māngaro ranei.
Me te methyl cellulose, e kiia ana hoki he hypromatose, hydroxypropyl whero o te miro, me te pakeke o te polymerization o te polymerization o te polymerization Ko te muka Alkali kei roto i nga waahanga e hiahiatia ana. Whakanohia te muka alkali ki te Kettletific Chettle, taapiri i te Opleyle Oxide methyl chloride kia raupapa, ka whakanuihia i te 50 haora, ko te pehanga teitei te 1.8MA. Na ka tapirihia he nui o te waikawa hydrochloric me te waikawa oxalic ki te wai wera i te 90 ° C ki te horoi i te rauemi ki te whakawhānui i te rahi, katahi ka mutu ka taea te horoi. Whānuitia i roto i te hanga, te ahumahi matū, te peita, te rongoa, te umanga a te ope taua me etahi atu mara, ko te aukati, he marara, he papatipu, ko te Thickener, etcker, Etcken, etc.
Ka taea te whakamahi i te Eterrch Thydroxypropyl hei whakanui mo nga hua-a-cement, nga hua e pa ana ki te gypsum me nga hua konupora. He pai te hototahi me etahi atu whakaraeraetanga whare. I whakamahia tahi me te hpmcycellulose ether, ka taea e te mate te whakamahi i te hpmc i te tau 20% -30%.
