I-Hydroymethylmethylecellulose; i-hydroxyethyl methyl cellulose; i-hydroxymethyl ethyl cellulose.

Ukubhaliswa kweCAS: 9032-42-2

Ulwakhiwo lweMolekyuli:

Iimpawu zeMveliso:

1. Ukubonakala: I-HEMC imhlophe okanye iphantse ibe ngumgubo omhlophe; ayinavumba kwaye ayinancasa.

2. I-Solubility: Uhlobo lwe-H kwi-HEMC lunokuchithwa emanzini angaphantsi kwe-60 ℃, kwaye uhlobo lwe-L lunokuchithwa kuphela emanzini abandayo. I-HEMC iyafana ne-HPMC kwaye ayinyibiliki kwizinyibilikisi ezininzi zendalo. Emva kokunyanga kwendawo, i-HEMC ihlakaza emanzini abandayo ngaphandle kwe-agglomeration kwaye ichithe ngokukhawuleza, kodwa inokuchithwa ngokukhawuleza ngokulungelelanisa ixabiso layo le-PH kwi-8-10.

3. Uzinzo lwexabiso le-PH: I-viscosity itshintsha kancinci ngaphakathi kwinqanaba le-2-12, kwaye i-viscosity iyancipha ngaphaya kolu luhlu.

4. Ukulunga: izinga lokupasa kwe-80 mesh yi-100%; ireyithi yokupasa ye-100 mesh yi-≥99.5%.

5. Ubunzima obuchanekileyo bobuxoki: 0.27-0.60g / cm3.

6. Ubushushu bokubola bungaphezulu kwe-200℃, kwaye buqala ukutshisa kwi-360℃.

7. I-HEMC inokuqina okuphawulekayo, ukuzinza kokumiswa, ukusabalalisa, ukudibanisa, ukubumba, ukugcinwa kwamanzi kunye nezinye iimpawu.

8. Ngenxa yokuba imveliso iqukethe iqela le-hydroxyethyl, ubushushu be-gel yemveliso bufikelela kwi-60-90℃. Ukongeza, iqela le-hydroxyethyl line-hydrophilicity ephezulu, eyenza ukuba umgangatho wemveliso ubopheleleke kakuhle. Ngokukodwa ekwakhiweni kweqondo lokushisa elitshisayo neliphezulu ehlobo, i-HEMC inokugcinwa kwamanzi aphezulu kune-methyl cellulose ye-viscosity efanayo, kwaye izinga lokugcinwa kwamanzi alikho ngaphantsi kwe-85%.

Ukubaluleka

Njenge-agent esebenzayo, i-hydroxyethyl methyl cellulose HEMC inezi mpawu zilandelayo ngaphezu kokuqina, ukumiswa, ukudibanisa, ukudibanisa, ukwenza ifilimu, ukusabalalisa, ukugcina amanzi kunye nokubonelela ngee-colloids ezikhuselayo:

(1) I-Hydroxyethyl methyl cellulose I-HEMC iyanyibilika kumanzi ashushu okanye abandayo, okwenza ibe neentlobo ezininzi ze-solubility kunye neempawu ze-viscosity, oko kukuthi, i-gelation engekho-thermal;

(2) I-Hydroxyethyl methyl cellulose I-HEMC inokuhlalisana kunye nolunye uluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, kunye neetyuwa, kwaye i-thickener egqwesileyo kwi-high-concentration electrolyte solutions;

(3) I-HEMC inokugcinwa kwamanzi okunamandla kune-methyl cellulose, kwaye ukuzinza kwayo kwe-viscosity, i-dispersibility, kunye nokumelana ne-mildew kunamandla kune-cellulose ye-hydroxyethyl.

Indlela yokulungiselela isisombululo

(1) Yongeza umlinganiselo othile wamanzi acocekileyo kwisikhongozeli;

(2) Yongeza i-hydroxyethyl methyl cellulose HEMC phantsi kwesantya esisezantsi, kwaye ugxobhoze de yonke i-hydroxyethyl methyl cellulose ichithwe ngokulinganayo;

(3) Ngokujonga idatha yethu yovavanyo lobugcisa, kucetyiswa ngamandla ukuba yongeze emva kokuba i-emulsion ye-polymer yongezwa (oko kukuthi, i-hydroxyethyl methyl celluloseHEMCixutywe kwangaphambili kunye ne-ethylene glycol okanye ipropylene glycol).

Usubudala

Kwimizi-mvelisoisakhiwoimathiriyeli,ibakala lokwakha HEMCifanelekileizinto zokuncamathelisa iithayile, iiplasta zesamente, udaka olomileyo oluxutyiweyo, ukuzilinganisa, udaka lwegypsum,Ipeyinti yelatex, izibophelelo zemathiriyeli yokwakha, amanye amasimi okwakha, ukugrumba indawo yeoli, imveliso yokhathalelo lomntu, iiarhente zokucoca, njl. njl., esetyenziswa ngokubanzi njengezinto ezityebisayo, izinto ezikhuselayo, izinto zokuncamathelisa, izinto ezincamathelayo, izinzisi, kunye neearhente zokuxhoma nazo zingasetyenziswa njengejeli zehydrophilic, imathiriyeli yematrix. , ukulungiselela i-matrix-uhlobo oluzinzileyo lwe-release-release preparations, kwaye lunokusetyenziswa njengezizinzisi ekutya, njl njl.

Pukumangalela kunye nokugcinwa

(1) Epakishwe kwi-paper-plastic composite polyethylene bag okanye isikhwama sephepha, i-25KG / isikhwama;

(2) Gcina umoya uqukuqela kwindawo yokugcina, kuphephe ukukhanya kwelanga, kwaye uzigcine kude nemithombo yomlilo;

(3) Ngenxa yokuba i-hydroxyethyl methyl cellulose HEMC i-hygroscopic, akufanele ibonakale emoyeni. Iimveliso ezingasetyenziswanga kufuneka zitywinwe kwaye zigcinwe, kwaye zikhuselwe kumswakama.
