Vasega fale MHEC

Vasega fale MHEC Methyl HydroxyethylCeluloseose pauta pa'epa'e e leai se manogi, e leai se tofo, e le'o'ona e mafai ona fa'amavae i le vai malulu e fai ai se vaifofo manino. O loʻo i ai uiga o le mafiafia, faʻapipiʻi, faʻasalalau, emulsification, faʻapipiʻi ata, faʻamalolo, adsorption, gelation, gaioiga i luga, faʻamauina o le susu ma le colloid puipuia. Talu ai o le vaifofo vai o loʻo i ai galuega faʻamalosi i luga, e mafai ona faʻaaogaina e avea o se mea e puipuia ai colloidal, emulsifier ma dispersant. Fau fale MHEC methyl Hydroxyethylcellulose vaifofo vai e lelei le hydrophilicity ma o se vailaau lelei le taofia o le vai. O le hydroxyethyl methyl cellulose o loʻo i ai vaega o le hydroxyethyl, o lea e lelei ai le anti-moli, lelei le faʻamautuina o le viscosity ma le anti-mildew i le taimi umi o le teuina.

Amioga fa'aletino ma kemisi:

Fa'aaliga: MHEC e pa'epa'e pe toetoe a pa'epa'e fibrous po'o le pa'u pa'epa'e; leai se manogi.

Solubility: MHEC e mafai ona solo i le vai malulu ma le vai vevela, L faʻataʻitaʻiga e naʻo le vai malulu, MHEC e le mafai ona faʻafefe i le tele o solvents organic. A maeʻa togafitiga luga, faʻasalalau le MHEC i le vai malulu e aunoa ma le faʻapipiʻiina, ma solo lemu, ae mafai ona vave faʻamavaeina e ala i le fetuunaʻi o lona tau PH o 8 ~ 10.

PH mautu: O le viscosity e suia laitiiti i totonu o le va o le 2 ~ 12, ma o le viscosity e faʻaitiitia i tua atu o lenei laina.

Granularity: 40 mesh pass fua faatatau ≥99% 80 mesh pass fua faatatau 100%.

Fa'aaogāga 

Fausia vasega MHEC methyl Hydroxyethyl cellulose e mafai ona faaaogaina e avea o se colloid puipuiga, emulsifier ma dispersant ona o lona galue malosi i luga o lona vaifofo vai. O fa'ata'ita'iga o ana fa'aoga e fa'apea:

1. Le a'afiaga o le methylhydroxyethylcellulose i luga o le fa'atinoga o le sima. Fau fale MHEC methylHydroxyethylcellulose o se pa'epa'e pa'epa'e e leai se manogi, leai se tofo, e mafai ona fa'amavaeina i le vai malulu e fausia ai se vaifofo viscous manino. O loʻo i ai uiga o le mafiafia, faʻapipiʻi, faʻasalalau, emulsification, faʻapipiʻi ata, faʻamalolo, adsorption, gelation, gaioiga i luga, faʻamauina o le susu ma le colloid puipuia. Talu ai ona o le vaifofo vai i luga o galuega galue malosi, e mafai ona faʻaaogaina e avea o se colloid puipuia, emulsifier ma dispersant.Building grade MHEC methyl Hydroxyethyl cellulose vai vaifofo ei ai hydrophilicity lelei ma o se sooupu e taofia vai lelei.
2. Saunia se vali faʻamalolo ma le maualuga o le fetuutuunaʻi, lea e faia i vaega nei i le mamafa o mea mataʻutia: 150-200g o vai faʻafefeteina; 60-70g o le emulsion acrylic mama; 550-650g o le calcium mamafa; 70-90g o talc; 30-40g o le methyl cellulose vaifofo vai; 10-20g o le lignoscellulose vaifofo vai; 4-6g o fesoasoani e fai ata tifaga; 1.5-2.5g o vailaau faʻamaʻi faʻamaʻi; 1.8-2.2g o faʻasalalau; 1.8-2.2g o le susu susu; Mafiafia 3.5-4.5g; ethylene glycol 9-11g; o le Faufale vasega MHEC vaifofo vai e faia i le 2-4% Fale fale MHEC fa'amavaeina i le vai; o lealava selulosavaifofo e faia i le 1 -3%alava selulosae faia i le solo i le vai.

Auala e gaosia aiVasega fale MHEC？

O legaosigaauala o le Faufale vasega MHEC methyl hydroxyethyl cellulose o loʻo faʻaaogaina le cotton faʻamamaina e avea o se mea mata ma ethylene oxide o loʻo faʻaaogaina e fai ma sui etherifying e saunia ai le fale MHEC. O mea mataʻina mo le saunia o le fale MHEC o loʻo saunia i vaega i le mamafa: 700-800 vaega o toluene ma isopropanol faʻafefiloi e pei o le solvent, 30-40 vaega o le vai, 70-80 vaega o le sodium hydroxide, 80-85 vaega o le cotton faʻamamaina, mama 20-28 vaega o le oxyethane, 80-90 vaega o le methyl chloride, 16-19 vaega ole acetic acid; o laasaga fa'apitoa e fa'apea:

I le laasaga muamua, faʻaopopo se faʻafefiloi o toluene ma le isopropanol, vai, ma le sodium hydroxide i totonu o le ulo tali, faʻaeʻe le vevela i le 60-80 ° C, ma taofi mo le 20-40 minute;

O le laasaga lona lua, alkalization: faʻamafanafana mea o loʻo i luga i le 30-50 ° C, faʻaopopo le cotton faʻamamaina, faʻafefe ma le faʻafefiloi o toluene ma le isopropanol, faʻamalo i le 0.006Mpa, faʻatumu i le nitrogen mo le 3 sui, ma fai alkalis pe a uma ona sui. e fa'apea: ole taimi ole alkalization e 2 itula, ma le vevela ole alkalization ole 30℃-50℃;

O le laasaga lona tolu, etherification: ina ua uma le alkalization, o le reactor ua aveese i le 0.05～0.07MPa, ethylene oxide ma le methyl chloride ua faʻaopoopoina ma teuina mo le 30～50 minute; le vaega muamua o le etherification: 40～60℃, 1.0～2.0 Itula, o le mamafa e pulea i le va o le 0.15-0.3Mpa; o le vaega lona lua o le etherification: 60～90℃, 2.0～2.5 itula, o le mamafa e pulea i le va o le 0.4-0.8Mpa;

O le laasaga lona ono, faʻamago centrifugal: o mea fufulu e ave i totonu o le mea faʻagogo e ala i se centrifuge sikulima faʻalava, o mea e faʻamago i le 150-170 ° C, ma mea mamago e nutimomoia ma afifi.

Faʻatusatusa i le cellulose ether gaosiga o loʻo i ai nei, o le taimi neiauala gaosigafa'aaoga le ethylene oxide e fai ma sui etherifying e saunia ai le vasega Faufale MHEC methyl hydroxyethyl cellulose, ma ona o lo'o i ai vaega hydroxyethyl, o lo'o i ai le malosi antifungal lelei. Lelei viscosity mautu ma mildew tetee i taimi umi teuina. E mafai ona suia isi ethers cellulose.

Bvasega aoga MHECole cellulose ether derivatives,O le cellulose ether o se mea fa'ameamea vaila'au fa'alelei ma le tele o fa'aoga e faia mai le cellulose polymer masani e ala i togafitiga vaila'au. Talu ai ona o le cellulose nitrate ma le cellulose acetate na faia i le 19th seneturi, ua atiae e tagata kemisi le tele o faasologa o mea e maua mai i le cellulose ethers. O lo'o fa'aauau pea ona su'esu'eina matā'upu fa'aoga fou ma o lo'o a'afia ai le tele o vaega tau alamanuia. Cellulose ether oloa e pei o le sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) Ma methyl hydroxypropyl cellulose (MHPC) ma isi cellulose ethers ua lauiloa o "Alamanuia monosodium glutamate" ma fale fale MHEC ua faʻaaogaina lautele i faʻapipiʻi taʻavale, sima mago, sima ma gypsum plasters etc.
