Ibikoresho byingenzi bya gypsumu yoroheje-selile ether

1. Ibikoresho bito bya selile

Cellulose ether yo kubaka ni polymer idafite amazi-elegitoronike inkomoko yayo:

Cellulose (ibiti biva mu mbaho ​​cyangwa ipamba), hydrocarbone ya halogene (methane chloride, Ethyl chloride cyangwa izindi ntera ndende), ibice bya epoxy (okiside ya Ethylene, okiside ya propylene, nibindi)

HPMC-Hydroxypropyl Methyl Cellulose Ether

HEC-Hydroxyethyl Cellulose Ether

HEMC-Hydroxyethyl Methyl Cellulose Ether

EHEC-Ethyl Hydroxyethyl Cellulose Ether

MC-methyl selulose ether

2. Ibyiza bya selile ether

Ibiranga selile ya selile biterwa na:

Impamyabumenyi ya Polymerisation DP Umubare wibice bya glucose-viscosity

Abasimbuye nintera yabo yo gusimburwa, urwego rwuburinganire bwabasimbuye - bagena ikibanza cyo gusaba

Ingano y'ibice —- Gukemura

Kuvura isura (ni ukuvuga gutinda guseswa) —- igihe cyo kwijimisha kijyanye na pH agaciro ka sisitemu

Impamyabumenyi yo Guhindura —- Kunoza imitekerereze ya sag no gukora bya selile ya ether.

3. Uruhare rwa selile ether - kubika amazi

Cellulose ether ni urunigi rwa polymer rugizwe na β-D-glucose.Itsinda rya hydroxyl muri molekile na atome ya ogisijeni kuri ether ya rugingo ikora hydrogène hamwe na molekile y'amazi, ikwirakwiza molekile y'amazi hejuru y'urunigi rwa polymer kandi igahuza molekile.Mu munyururu, itinda guhinduka kwamazi kandi igatwarwa nigice cyibanze.

Inyungu zitangwa nuburyo bwo kubika amazi ya selile ethers:

Ntibikenewe koza urwego shingiro, uburyo bwo kuzigama

kubaka neza

imbaraga zihagije

4. Uruhare rwa selile ether - ingaruka zo kubyimba

Ether ya selile irashobora kongera ubufatanye hagati yibigize gypsumu ishingiye kuri minisiteri, ibyo bikaba bigaragarira mu kongera ubwinshi bwa minisiteri.

Inyungu nyamukuru zitangwa no kubyibuha kwa selile ya selile ni:

Mugabanye ivu

Ongera gufatira ku shingiro

Mugabanye kugabanuka kwa minisiteri

gumana na minisiteri

5. Uruhare rwa selile ether - ibikorwa byubuso

Ether ya selile irimo amatsinda ya hydrophilique (hydroxyl group, ether bonds) hamwe na hydrophobique (matsinda ya methyl, amatsinda ya Ethyl, impeta ya glucose) kandi ni surfactant.

.

Inyungu nyamukuru zitangwa nigikorwa cyo hejuru cya selile ethers ni:

Ingaruka zo guhumeka ikirere (gusiba neza, ubucucike buke, modulus nkeya ya elastike, kurwanya ubukonje)

Gutose (byongera gufatira hamwe)

6. Ibisabwa bya gypsumu yumucyo wa selile ya ether

(1).Kubika amazi meza

(2).Gukora neza, nta guteka

(3).Gusiba neza

(4).Kurwanya cyane

(5).Ubushyuhe bwa gel buri hejuru ya 75 ° C.

(6).Igipimo cyo gusesa vuba

(7).Nibyiza kugira ubushobozi bwo kwinjiza umwuka no guhagarika umwuka mubi muri minisiteri

11. Nigute ushobora kumenya igipimo cya selile ether

Kuhomesha plaster, birakenewe kugumana amazi ahagije muri minisiteri mugihe kirekire kugirango ugire imikorere myiza kandi wirinde kumeneka hejuru.Muri icyo gihe, selulose ether igumana amazi akwiye igihe kinini kugirango minisiteri igire gahunda ihamye.

Ingano ya selulose ether iterwa na:

Viscosity ya selile ether

Igikorwa cyo gukora selile ya ether

Ibirimo Gusimbuza no Gukwirakwiza Cellulose Ether

Ingano Ingano Ikwirakwizwa rya Cellulose Ether

Ubwoko nibigize gypsumu ishingiye kuri minisiteri

Ubushobozi bwo kwinjiza amazi murwego rwibanze

Gukoresha Amazi Kubisanzwe Bisanzwe bya Gypsumu ishingiye kuri Mortar

Gushiraho igihe cya gypsumu ishingiye kuri minisiteri

Ubwinshi bwubwubatsi nibikorwa byubwubatsi

Imiterere yubwubatsi (nkubushyuhe, umuvuduko wumuyaga, nibindi)

Uburyo bwo kubaka (gusiba intoki, gutera imashini)
