Ma muli o nā kumu e like me ke ea wela, ka haʻahaʻa, ka makani makani, a me ka wikiwiki o ka makani, e hoʻopilikia ʻia ka nui o ka volatilization o ka wai i nā huahana gypsum.
No laila inā i loko o ka gypsum-based leveling mortar, caulk, putty, a i ʻole gypsum-based self-leveling, hydroxypropyl methylcellulose ether (HPMC) ke kuleana koʻikoʻi.
Paʻa wai o BAOSHUIXINGHPMC
Hiki i ka hydroxypropyl methylcellulose (HPMC) maikaʻi ke hoʻoponopono i ka pilikia o ka paʻa ʻana o ka wai ma lalo o ka wela kiʻekiʻe.
ʻO kāna mau pūʻulu methoxy a me ka hydroxypropoxy ua puʻunaue like ʻia ma ke kaulahao mole cellulose, hiki ke hoʻomaikaʻi i ka hiki o nā ʻātoma oxygen ma ka hydroxyl a me ka ether paʻa e hui pū me ka wai e hana i nā paʻa hydrogen, e hoʻolilo i ka wai manuahi i ka wai paʻa, a laila e hoʻomalu pono i ka evaporation. o ka wai i hoʻokumu ʻia e ka wela wela e hoʻokō ai i ka paʻa wai kiʻekiʻe.
Hiki ke kūkulu ʻia o SHIGONGXINGHPMC
Hiki ke komo koke nā huahana cellulose ether i koho ʻia i loko o nā huahana gypsum me ka ʻole o ka agglomeration, a ʻaʻohe hopena maikaʻi ʻole i ka porosity o nā huahana gypsum i hoʻōla ʻia, pēlā e hōʻoia ai i ka hana hanu o nā huahana gypsum.
He hopena hoʻopaneʻe kona akā ʻaʻole pili i ka ulu ʻana o nā kristal gypsum; hōʻoia ʻo ia i ka hiki ke hoʻopaʻa ʻia o ka mea i ka ʻili kumu me ka adhesion pulu kūpono, hoʻomaikaʻi nui i ka hana hana ʻana o nā huahana gypsum, a maʻalahi hoʻi e laha me ka ʻole o nā mea paʻa.
Lubricity o RUNHUAXINGHPMC
High-quality hydroxypropyl methylcellulose hiki e likely a me ka pono hoopuehu i loko o ka sima a me ka gypsum-ma muli huahana, a hoʻopili i nā mea paʻa paʻa a pau, a hana i ka wetting kiʻiʻoniʻoni, a me ka makū i loko o ke kumu, e lohi dissolve no ka lōʻihi manawa. hoʻokuʻu, a hana i ka hopena hydration me nā mea gelling inorganic, a laila e hōʻoia i ka ikaika paʻa a me ka ikaika compressive o ka mea.
