Ibakala lokwakhiwa kwe-HEMC

Ibakala lokwakha i-HEMC I-Hydroxyethyl Methyl Cellulose yaziwa ngokuba yi-Methyl Hydroxyethyl Cellulose (MHEC), imhlophe okanye i-off-white powder, ayinavumba kwaye ayinambitheki, i-soluble Kuwo omabini amanzi ashushu kunye namanzi abandayo.Ibakala lokwakha i-HEMC ingasetyenziswa njengesamente, igypsum, i-agent ye-lime gelling, i-arhente yokugcina amanzi, yinto egqwesileyo yokuxutywa kwezinto zokwakha umgubo.

Iziteketiso: i-hydroxyethyl methyl cellulose;i-hydroxyethyl methyl cellulose;i-hydroxymethyl ethyl cellulose;I-2-hydroxyethyl methyl ether cellulose, i-Methylhydroxyethylcellulose;iSelulosi;I-2-hydroxyethyl methyl ether;I-HEMC;

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 lokuphumelela 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 kakhulu ukuba yongeze emva kokuba i-emulsion ye-polymer yongezwa (oko kukuthi, i-hydroxyethyl methyl cellulose HEMC ixutywe ngaphambili kunye ne-ethylene glycol okanye i-propylene glycol).

Usubudala

Kwizinto zokwakha kwimizi-mveliso, ibakala lokwakha i-HEMC lilungele ukuncamathelisa iithayile, iiplaster zesamente, udaka olomileyo oluxubeneyo, ukuzilinganisa ngokwakho, udaka lwegypsum, ipeyinti yelatex, izibophelelo zezinto zokwakha, amanye amasimi okwakha, ukugrumba indawo yeoli, iimveliso zokhathalelo lomntu, iiarhente zokucoca, njl. , esetyenziswa ngokubanzi njengama-thickeners, ii-agent ezikhuselayo, i-adhesives, stabilizers, kunye ne-suspending agents nazo zingasetyenziswa njenge-hydrophilic gels, izinto ze-matrix, ukulungiselela amalungiselelo okukhululwa okuzinzile kwe-matrix, kwaye ingasetyenziswa njengezinzisi ekutyeni, 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.

20'FCL: 12Ton ene-palletized, 13.5Ton ngaphandle kwepalletized.
