Ojiji na ịkpachapụ anya nke Hydroxypropyl Methyl Cellulose (HPMC)

Kedu ihe bụ viscosity kwesịrị ekwesị nke hydroxypropyl methylcellulose (HPMC)?

Putty ntụ ntụ n'ozuzu bụ 100,000 yuan, na ihe ndị a chọrọ maka ngwa agha dị elu, na 150,000 yuan chọrọ maka ojiji dị mfe. Ọzọkwa, ọrụ kachasị mkpa nke HPMC bụ njide mmiri, na-esote thickening. Na ntụ ntụ putty, ọ bụrụhaala na njide mmiri dị mma na viscosity dị ala (70,000-80,000), ọ ga-ekwe omume. N'ezie, ka viscosity dị elu, ka mma na-ejigide mmiri. Mgbe viscosity gafere 100,000, viscosity ga-emetụta njide mmiri. Ọ bụghị ọtụtụ ihe ọzọ.

Kedu ụzọ mgbasa nke hydroxypropyl methylcellulose (HPMC)?

(1) Ọcha: Ọ bụ ezie na Baidu enweghị ike ikpebi ma HPMC dị mfe iji, ma ọ bụrụ na agbakwunyere ndị na-acha ọcha n'oge usoro mmepụta, àgwà ya ga-emetụta. Otú ọ dị, ọtụtụ n'ime ngwaahịa ndị dị mma nwere ezigbo ọcha.

(2) Ịdị mma: Ịdị mma nke HPMC n'ozuzu nwere ntupu 80 na ntupu 100, na ntupu 120 dị obere. Ọtụtụ HPMC emepụtara na Hebei bụ ntupu 80. Ka mma dị mma, n'ozuzu n'ikwu okwu, ka mma.

(3) Mfefe ọkụ: tinye hydroxypropyl methylcellulose (HPMC) n'ime mmiri iji mepụta colloid transperent, ma lelee nnyefe ọkụ ya. Ka ọkụ na-ebufe ọkụ dị ukwuu, ọ ka mma, na-egosi na ọ dị obere insoluble na ya. . The permeability nke vetikal reactors bụ n'ozuzu ezi, na nke kehoraizin reactors bụ njọ, ma ọ pụtaghị na àgwà nke vetikal reactors dị mma karịa nke kehoraizin reactors, na ngwaahịa àgwà kpebisiri ike site ọtụtụ ihe. (4) Ike ndọda pụrụ iche: Ka nnukwu ike ndọda ahụ na-ebuwanye ibu, ka ọ na-akawanye mma. Ihe a kapịrị ọnụ bụ nnukwu, n'ozuzu n'ihi na ọdịnaya nke hydroxypropyl otu dị na ya dị elu, na ọdịnaya nke hydroxypropyl otu dị elu, njide mmiri dị mma.

Gịnị bụ isi ọrụ nke ngwa nke HPMC na putty ntụ ntụ, na ọ na-eme chemically?

N'ime ntụ ntụ putty, HPMC na-arụ ọrụ atọ nke ịgbara mmiri, njigide mmiri na ihe owuwu.

Ọkpụkpụ: Enwere ike ịgbatị cellulose ka ọ kwụsịtụ ma mee ka ngwọta ya bụrụ otu elu na ala, ma guzogide ịda mbà n'obi.

Njide mmiri: mee ka ntụ ntụ putty kpoo nwayọọ nwayọọ, ma nyere calcium ash aka imeghachi omume n'okpuru ọrụ mmiri.

Mwube: Cellulose nwere mmetụta mmanu mmanu, nke nwere ike ime ka uzuzu putty nwee ezigbo ihe owuwu. HPMC anaghị eso na mmeghachi omume kemịkalụ ọ bụla, mana ọ na-arụ naanị ọrụ inyeaka. Ịgbakwunye mmiri na ntụ ntụ na-etinye ya na mgbidi bụ mmeghachi omume kemịkal, n'ihi na a na-emepụta ihe ọhụrụ. Ọ bụrụ na i wepụ ntụ ntụ na mgbidi ahụ site na mgbidi, gwerie ya na ntụ ntụ, ma jiri ya mee ihe ọzọ, ọ gaghị arụ ọrụ n'ihi na e mepụtala ihe ọhụrụ (calcium carbonate). ) kwa.

Isi ihe dị na ntụ ntụ calcium ash bụ: ngwakọta nke Ca (OH) 2, CaO na obere ego CaCO3, CaO + H2O = Ca(OH) 2 -Ca (OH) 2 + CO2 = CaCO3↓+ H2O ash calcium N'ime mmiri na ikuku N'okpuru ọrụ nke CO2, calcium carbonate na-emepụta, ebe HPMC na-ejigide mmiri naanị, na-enyere aka mmeghachi omume dị mma nke calcium ash, ma ghara itinye aka na mmeghachi omume ọ bụla n'onwe ya.

Mmekọrịta dị n'etiti viscosity na okpomọkụ nke HPMC, gịnị ka a ga-akwụ ụgwọ na ngwa bara uru?

Viscosity nke HPMC na-adaba na ọnọdụ okpomọkụ, ya bụ, viscosity na-abawanye ka okpomọkụ na-ebelata. Viscosity nke ngwaahịa anyị na-ezokarị aka na nsonaazụ nnwale nke 2% mmiri mmiri na-ekpo ọkụ na ogo 20 Celsius.

N'ime ngwa ndị bara uru, ekwesịrị iburu n'uche na n'ebe ndị nwere nnukwu okpomọkụ dị iche n'etiti oge okpomọkụ na oyi, a na-atụ aro ka iji obere viscosity dị ntakịrị na oyi, nke na-eme ka ọ dịkwuo mma n'ịrụ ụlọ. Ma ọ bụghị ya, mgbe okpomọkụ dị ala, viscosity nke cellulose ga-abawanye, na mmetụta aka ga-adị arọ mgbe ịchacha.

Viscosity ọkara: 75000-100000 a na-ejikarị maka putty

Ihe kpatara ya: ezigbo njide mmiri

Nnukwu viscosity: 150000-200000 na-ejikarị maka polystyrene urughuru mkpuchi ngwa agha roba ntụ ntụ na ngwa agha mkpuchi microbead vitrified.

Ihe kpatara ya: elu viscosity, ngwa agha adịghị mfe ịdapụ, sagging, nke na-eme ka ihe owuwu ahụ dịkwuo mma.
