Papa kūkulu hale HEMC

ʻO ka papa hana HEMC Hydroxyethyl Methyl Cellulose ʻike ʻia ʻo Methyl Hydroxyethyl Cellulose (MHEC), he keʻokeʻo a keʻokeʻo keʻokeʻo paha, ʻaʻala a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i ka wai wela a me ka wai anuanu. Hiki ke hoʻohana ʻia ka papa hana HEMC e like me ka cement, gypsum, lime gelling agent, wai hoʻopaʻa wai, he mea hoʻohui maikaʻi loa no nā mea hana pauka.

Nā inoa inoa: hydroxyethyl methyl cellulose; hydroxyethyl methyl cellulose; hydroxymethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose, Methylhydroxyethylcellulose; Cellulose; 2-hydroxyethyl methyl ether; HEMC;

Hoʻolālā Molekala:

Nā hiʻohiʻona huahana:

1. Nānā: HEMC keʻokeʻo a aneane keʻokeʻo pauka; ʻala ʻole a ʻono ʻole.

2. Solubility: Hiki ke hoʻoheheʻe ʻia ke ʻano H ma HEMC i ka wai ma lalo o 60 ℃, a hiki ke hoʻoheheʻe ʻia ke ʻano L i ka wai anuanu. He like ka HEMC me HPMC a hiki ʻole ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik. Ma hope o ka mālama ʻana i ka ʻili, hoʻopuehu ʻo HEMC i ka wai anuanu me ka ʻole o ka agglomeration a hoʻoheheʻe mālie, akā hiki ke hoʻopau koke ʻia ma ka hoʻololi ʻana i kāna waiwai PH i 8-10.

3. Paʻa ka waiwai PH: Hoʻololi liʻiliʻi ka viscosity i loko o ka laulā o 2-12, a ua hoʻohaʻahaʻa ʻia ka viscosity ma waho o kēia pae.

4. Fineness: ʻo ka hala o 80 mesh he 100%; ʻO ka helu hele o 100 mesh he ≥99.5%.

5. Kaumaha kiko'ī wahaheʻe: 0.27-0.60g/cm3.

6. Aia ka mahana decomposition ma luna o 200 ℃, a hoʻomaka ia e wela ma 360 ℃.

7. He mānoanoa nui ka HEMC, ka paʻa o ka hoʻokuʻu ʻana, ka dispersibility, ka hui ʻana, ka moldability, ka paʻa wai a me nā ʻano ʻē aʻe.

8. No ka mea aia ka hui hydroxyethyl i ka huahana, hiki i ka mahana gel o ka huahana i 60-90 ℃. Eia kekahi, he hydrophilicity kiʻekiʻe ka pūʻulu hydroxyethyl, kahi e hana maikaʻi ai ka huahana paʻa. ʻOi loa i ka hana wela a me ke kiʻekiʻe o ke kauwela, ʻoi aku ka nui o ka mālama ʻana o ka wai ma mua o ka methyl cellulose o ka viscosity like, a ʻaʻole i emi ka nui o ka wai ma mua o 85%.

Papa Hua   

Mea nui

Ma ke ʻano he mea hana ma luna, ʻo ka hydroxyethyl methyl cellulose HEMC nā hiʻohiʻona ma lalo o ka mānoanoa, hoʻopaneʻe, hoʻopaʻa, emulsifying, hana kiʻiʻoniʻoni, hoʻopuehu, mālama wai a hāʻawi i nā colloids pale:

(1) Hydroxyethyl methyl cellulose HEMC hiki ke hoʻoheheʻe ʻia i loko o ka wai wela a i ʻole ka wai anuanu, e hana ana i kahi ākea ākea o ka solubility a me nā ʻano viscosity, ʻo ia hoʻi, non-thermal gelation;

(2) Hiki i ka Hydroxyethyl methyl cellulose HEMC ke hui pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, a me nā paʻakai, a he mea mānoanoa maikaʻi loa no nā hopena electrolyte kiʻekiʻe;

(3) He ʻoi aku ka ikaika o ka mālama wai ʻana o ka HEMC ma mua o ka methyl cellulose, a ʻoi aku ka ikaika o kona kūpaʻa viscosity, dispersibility, a me ka maʻi maʻi ma mua o ka hydroxyethyl cellulose.

ʻano hoʻomākaukau hoʻonā

(1) Hoʻohui i ka nui o ka wai maʻemaʻe i ka pahu;

(2) Hoʻohui i ka HEMC hydroxyethyl methyl cellulose HEMC ma lalo o ka haʻahaʻa haʻahaʻa haʻahaʻa, a hoʻoulu a hiki i ka pau ʻana o ka hydroxyethyl methyl cellulose;

(3) Ma ka nānā 'ana i kā mākou 'ike loea ho'ā'o, ua paipai 'ia e ho'ohui ia ma hope o ka polymer emulsion i ho'ohui 'ia (ie, hydroxyethyl methyl cellulose HEMC ua hui mua ia me ka ethylene glycol a propylene glycol).

Usmakahiki

I loko o nā mea hana hale ʻoihana, kūpono ka HEMC hana no ka tile adhesive, plasters sima, maloʻo maloʻo i hui pū ʻia, hoʻopaʻa pono ʻia, gypsum plaster, pena latex, nā mea hoʻopaʻa hale, nā kahua kūkulu ʻē aʻe, ka ʻaila ʻaila, nā huahana mālama pilikino, nā mea hoʻomaʻemaʻe, etc. , hoʻohana maʻamau e like me nā mānoanoa, nā mea pale, nā mea hoʻopili, nā stabilizers, a me nā mea hoʻopaneʻe hiki ke hoʻohana ʻia e like me nā gels hydrophilic, nā mea matrix, hoʻomākaukau ʻana i ka matrix-type sustained-release hoʻomākaukau, a hiki ke hoʻohana ʻia i stabilizers i nā meaʻai, etc. .

Packaging a me ka waiho ʻana

(1) Hoʻopili ʻia i loko o ka ʻeke polyethylene composite pepa a i ʻole ʻeke pepa, 25KG / ʻeke;

(2) E mālama i ka ea e kahe ana ma kahi e waiho ai, e pale i ka malamalama o ka lā, a e pale i nā kumu ahi;

(3) No ka mea he hygroscopic ka hydroxyethyl methyl cellulose HEMC, ʻaʻole pono e ʻike ʻia i ka lewa. Pono e hoʻopaʻa ʻia a mālama ʻia nā huahana i hoʻohana ʻole ʻia, a pale ʻia mai ka makū.

20'FCL: 12Ton me ka palletized, 13.5Ton me ka ʻole palletized.
