Koeke whare MHEC

Koeke whare MHEC

Koeke whare MHEC Methyl HydroxyethylCellulosehe paura ma karekau he kakara, he reka, he paitini ka taea te rewa ki roto i te wai matao kia puta he wairewa puataata. Kei a ia nga ahuatanga o te matotoru, te honohono, te marara, te emulsification, te hanga kiriata, te whakatārewatanga, te adsorption, te gelation, te mahi mata, te pupuri makuku me te colloid tiaki. I te mea ko te wairewa wai he mahi kaha ki te mata, ka taea te whakamahi hei kaihoko tiaki colloidal, emulsifier me te dispersant. Ko te reanga hanga whare MHEC methyl Hydroxyethylcellulose wairewa wai he pai te hydrophilicity, a, he pai te tiaki wai. Kei roto i te Hydroxyethyl methyl cellulose nga roopu hydroxyethyl, no reira he pai te kaha ki te aukati i te pokepokea, te pai o te whakapumautanga me te koriri i roto i te rokiroki mo te wa roa.

Āhuatanga ā-tinana me te matū:

Te ahua: Ko te MHEC he ma, he tata ma te kiri, he paura maramara ranei; haungakore.

Wairewa: Ka taea e te MHEC te memeha i roto i te wai matao me te wai wera, ka taea e te tauira L te memeha noa i te wai matao, karekau te MHEC i roto i te nuinga o nga whakarewa pararopi. I muri i te maimoatanga o te mata, ka marara te MHEC i roto i te wai makariri kaore he agglomeration, ka memeha haere, engari ka taea te whakakore wawe ma te whakatika i tana uara PH o 8 ~ 10.

Te pumau o te PH: He iti noa te huringa o te pokey i roto i te awhe o te 2~12, ka heke te pokey ki tua atu i tenei awhe.

Granularity: 40 mata reiti haere ≥99% 80 mata reiti haere 100%.

Kiato ahua: 0.30-0.60g/cm3.

Me pehea te whakaputaKoeke whare MHEC？

Ko tehangahangaKo te tikanga o te hanga whare MHEC methyl hydroxyethyl cellulose ko te miro parakore ka whakamahia hei rauemi mata, ka whakamahia te ethylene oxide hei kaihoko etherifying ki te whakarite whare MHEC. Ko nga rauemi mata mo te whakarite whare MHEC kua rite ki nga waahanga o te taumaha: 700-800 nga waahanga o te toluene me te ranunga isopropanol hei whakarewa, 30-40 nga waahanga o te wai, 70-80 nga waahanga o te konutai hydroxide, 80-85 nga waahanga o te miro para, mowhiti 20-28 nga waahanga o te oxyethane, 80-90 nga waahanga o te methyl chloride, 16-19 nga wahanga o te waikawa acetic glacial; ko nga taahiraa motuhake e whai ake nei:

I te taahiraa tuatahi, whakauruhia he ranunga o te toluene me te isopropanol, te wai, me te konutai waikawa ki roto i te kettle tauhohenga, whakaarahia te mahana ki te 60-80 ° C, ka pupuri mo te 20-40 meneti;

Ko te taahiraa tuarua, te whakamaaramatanga: whakamatao i nga rauemi o runga ake nei ki te 30-50°C, taapirihia te miro parakore, te rehu me te ranunga o te toluene me te isopropanol, ka rere ki te 0.006Mpa, whakakiia ki te hauota mo nga whakakapinga e 3, ka mahi i te kawakore i muri i te whakakapinga Ko enei e whai ake nei: ko te 2 haora te wa whakamaaramatanga, ko te 30 ℃ te pāmahana whakamahana-50℃;

Ko te taahiraa tuatoru, te etherification: i muri i te whakamaaramatanga, ka nekehia te reactor ki te 0.05～Ko te 0.07MPa, te ethylene oxide me te methyl chloride ka taapirihia ka pupuri mo te 30～50 meneti; te wahanga tuatahi o te whakamaarama: 40～60 ℃, 1.0～2.0 haora, ka whakahaerehia te pehanga i waenga i te 0.15-0.3Mpa; te waahanga tuarua o te whakamaarama: 60～90℃, 2.0～2.5 haora, ka whakahaerehia te pehanga i waenga i te 0.4-0.8Mpa;

Ko te tuawha o te taahiraa, te whakakorenga: taapirihia te waikawa acetic glacial i mua i mua ki te desolventizer, pehia ki roto i nga mea kua whakahiato mo te whakakore, whakanuia te pāmahana ki te 75～80 ℃ mo te whakakorenga, ka piki te mahana ki te 102 ℃, ka 68 te uara pH. Ka oti te whakakorenga; whakakīia te ipu wai whakamuri ki te wai tap kua rongoatia e te taputapu whakamuri osmosis i te 90 ℃～100 ℃;

Ko te rima o nga taahiraa, ko te horoinga centrifugal: ko nga mea kei te wha o nga taahiraa ka centrifuged e te centrifuge tīwiri whakapae, a ka whakawhitia nga mea kua wehea ki te ketere horoi ki tonu i te wai wera i mua mo te horoi i nga rauemi;

Ko te taahiraa tuaono, ko te whakamaroke centrifugal: ka haria nga mea kua horoia ki roto i te whakamaroke ma roto i te centrifuge tīwiri whakapae, ka whakamarokehia nga rauemi ki te 150-170°C, ka kuru, ka kohia nga mea maroke.

Ka whakatauritea ki te hangarau whakangao cellulose ether o naianei, o naianeitikanga whakaputaka whakamahi i te waikura ethylene hei kaihoko whakakorikori ki te whakareri i te whare MHEC methyl hydroxyethyl cellulose, a, na te mea kei roto nga roopu hydroxyethyl, he pai te kaha antifungal. He pai te whakapumautanga me te koriri i te wa e rokiroki ana mo te wa roa. Ka taea e ia te whakakapi i etahi atu ethers cellulose.

BMHEC reanga houhe pärönaki etera cellulose,Ko te Cellulose ether he rauemi matū pai polymer me te whānuitanga o nga whakamahinga i hangaia mai i te cellulose polymer taiao ma te maimoatanga matū. I te mea i hangaia te cellulose nitrate me te cellulose acetate i te rautau 1800, kua whakawhanakehia e nga tohunga kemu te maha o nga raupapatanga o te cellulose o nga etera cellulose. Kei te kitea nga waahi tono hou me te maha o nga waahanga ahumahi e uru ana. Ko nga hua ether cellulose penei i te konutai carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) me te methyl hydroxypropyl cellulose (MHPC) me etahi atu etera cellulose e mohiotia ana Ko te "monosodium glutamate ahumahi" me te MHEC o te whare kua whakamahia nuitia ki te whakapiri tira, moata maroke, ciment me te raima gypsum etc.
