15. He aha kekahi inoa no ka hydroxypropyl methylcellulose?

Pane: Hydroxypropyl Methyl Cellulose, English: Hydroxypropyl Methyl Cellulose Abbreviation: HPMC a i ʻole MHPC Alias: Hypromellose; Cellulose hydroxypropyl methyl ether; Hypromellose, Cellulose, 2-hydroxypropyl methyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.

16. He aha ka mea e pono e hoʻolohe i ka noi maoli o ka pilina ma waena o ka viscosity a me ka mahana o HPMC?

Pane: ʻO ka viscosity o ka HPMC he inversely proportional i ka mahana, ʻo ia hoʻi, piʻi ka viscosity i ka emi ʻana o ka mahana. ʻO ka viscosity o kahi huahana a mākou e ʻōlelo pinepine ai e pili ana i ka hopena hoʻāʻo o kāna 2% aqueous solution ma kahi mahana o 20 degere Celsius.

Ma nā hoʻohana pono, pono e hoʻomaopopo ʻia i nā wahi me nā ʻokoʻa wela nui ma waena o ke kauwela a me ka hoʻoilo, ua ʻōlelo ʻia e hoʻohana i kahi viscosity haʻahaʻa haʻahaʻa i ka hoʻoilo, ʻoi aku ka maikaʻi o ke kūkulu ʻana. A i ʻole, ke haʻahaʻa ka mahana, e piʻi ka viscosity o ka cellulose, a kaumaha ka lima i ka wā e ʻoki ai. Medium viscosity: 75000-100000 Hoʻohana nui ʻia no ka putty. Ke kumu: mālama maikaʻi i ka wai. ʻO ka viscosity kiʻekiʻe: 150000-200000 Hoʻohana nui ʻia no ka polystyrene particle thermal insulation mortar glue powder a me vitrified microbead thermal insulation mortar. Ke kumu: kiʻekiʻe viscosity, ʻaʻole maʻalahi ka mortar e hāʻule, kau, a hoʻomaikaʻi i ke kūkulu ʻana.

17. ʻO ka hoʻohana ʻana o HPMC i ka pauka putty, he aha ke kumu o nā ʻōhū i loko o ka pauka putty?

Pane: I loko o ka pauka putty, hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana. Mai komo i kekahi hopena. Nā kumu o nā ʻōhū: 1. E kau i ka wai nui. 2. ʻAʻole maloʻo ka papa lalo, e ʻoki wale i kahi papa ʻē aʻe ma luna, a maʻalahi ka huʻa.
