I-HEMC yenqanaba lokwakha

I-HEMC yenqanaba lokwakhaI-HydroxyethylMi-ethylCi-elliloseyaziwa ngokuba yiMethyl Hydroxyethyl Cellulose (MHEC), yonayimpuphu emhlophe okanye engemhlophe kangako, ayinavumba kwaye ayinancasa, iyanyibilikaKumanzi ashushu namanzi abandayo. I-HEMC yomgangatho wokwakha inokubaIsetyenziswa njengesamente, igypsum, i-lime gelling agent, i-arhente yokugcina amanzi, kwaye iyinto exutyiweyo kakuhle kwizixhobo zokwakha umgubo.

AIzithako: i-hydroxyethyl methyl cellulose; i-hydroxyethyl methyl cellulose; i-hydroxyethyl ethyl cellulose; i-2-hydroxyethyl methyl ether cellulose, iMethylhydroxyethylcellulose; iCellulose; i-2-hydroxyethyl methyl ether; iHEMC;

I-Hydroymethylmethylecellulose; i-hydroxyethylmethylcellulose; i-hydroxymethyl ethyl cellulose.

Ubhaliso lwe-CAS: 9032-42-2

Ulwakhiwo lweMolekyuli:

Iimpawu zeMveliso:

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

2. Ukunyibilika: Uhlobo lwe-H kwi-HEMC lunganyibilika emanzini angaphantsi kwama-60℃, kwaye uhlobo lwe-L lunganyibilika kuphela emanzini abandayo. I-HEMC iyafana ne-HPMC kwaye ayinyibiliki kwiintlambululi ezininzi ze-organic. Emva konyango lomphezulu, i-HEMC isasazeka emanzini abandayo ngaphandle kokudibana kwaye inyibilike kancinci, kodwa inokunyibilika ngokukhawuleza ngokulungelelanisa ixabiso layo le-PH ukuya kwi-8-10.

3. Uzinzo lwexabiso le-PH: I-viscosity ayitshintshi kangako phakathi koluhlu lwe-2-12, kwaye i-viscosity yonakala ngaphaya kolu luhlu.

4. Ubunzima: izinga lokupasa le-80 mesh yi-100%; izinga lokupasa le-100 mesh yi-≥99.5%.

5. Ubunzima obungeyonyani: 0.27-0.60g/cm3.

6. Ubushushu bokubola bungaphezulu kwama-200℃, kwaye buqala ukutsha kuma-360℃.

7. I-HEMC inokuqina okuphawulekayo, uzinzo lokumiswa, ukusasazeka, ukuhambelana, ukuguguleka, ukugcinwa kwamanzi kunye nezinye iimpawu.

8. Ngenxa yokuba imveliso ineqela le-hydroxyethyl, ubushushu bejeli yemveliso bufikelela kuma-60-90℃. Ukongeza, iqela le-hydroxyethyl linomoya ophezulu wokufudumala kwamanzi, nto leyo eyenza ukuba izinga lokubopha imveliso libe lihle. Ingakumbi xa kushushu kwaye kushushu kakhulu ehlotyeni, i-HEMC inokugcinwa kwamanzi okuphezulu kune-methyl cellulose ene-viscosity efanayo, kwaye izinga lokugcinwa kwamanzi alikho ngaphantsi kwama-85%.

Ibanga leMveliso

Ukubaluleka

Njenge-arhente esebenzayo kumphezulu, i-hydroxyethyl methyl cellulose HEMC ineempawu ezilandelayo ukongeza ekuqineni, ekumiseni, ekubopheni, ekuhlanganiseni, ekwenzeni ifilimu, ekusasazeni, ekugcineni amanzi nasekuboneleleni ngee-colloids ezikhuselayo:

(1) I-Hydroxyethyl methyl cellulose HEMC iyanyibilika emanzini ashushu okanye abandayo, nto leyo eyenza ukuba ibe neempawu ezahlukeneyo zokunyibilika kunye ne-viscosity, oko kukuthi, i-gelation engashushu;

(2) I-Hydroxyethyl methyl cellulose HEMC ingasebenza kunye nezinye iipolymers ezinyibilikayo emanzini, ii-surfactants, kunye neetyuwa, kwaye iyinto etyebisayo kakhulu kwizisombululo ze-electrolyte ezixineneyo kakhulu;

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

Indlela yokulungiselela isisombululo

(1) Yongeza umlinganiselo othile wamanzi acocekileyo kwisikhongozeli;

(2) Yongeza i-hydroxyethyl methyl cellulose HEMC phantsi kokuxuba ngesantya esiphantsi, uze uxube ude yonke i-hydroxyethyl methyl cellulose inyibilike ngokulinganayo;

(3) Ngenxa yedatha yethu yovavanyo lobuchwephesha, kucetyiswa kakhulu ukuba uyongeze emva kokuba kongezwe i-polymer emulsion (oko kukuthi, i-hydroxyethyl methyl cellulose).I-HEMCixutywe kwangaphambili ne-ethylene glycol okanye i-propylene glycol).

Usubudala

Kwimizi-mvelisoisakhiwoizixhobo,i-HEMC yenqanaba lokwakhaifanelekile kwii-adhesive yethayile, iiplasta zesamente, udaka oluxutyiweyo olomileyo, ukuzilinganisa, iplasta yegypsum,Ipeyinti yelatex, izihlanganisi zezinto zokwakha, ezinye iindawo zokwakha, ukubhola ioyile, iimveliso zokhathalelo lomntu, iiarhente zokucoca, njl.njl., ezisetyenziswa ngokubanzi njengezithambisi, iiarhente zokukhusela, izincamathelisi, iziqinisi, kunye neearhente zokuxhoma, ingasetyenziswa njengeejeli ezisebenzisa amanzi, izixhobo zematrix, ukulungiselela amalungiselelo okukhululwa okuqhubekekayo kohlobo lwematrix, kwaye ingasetyenziswa njengezithambisi ekutyeni, njl.njl. isiphumo.

Pukugoba kunye nokugcinwa

(1) Ipakishwe kwingxowa yeplastiki okanye kwingxowa yephepha edityanisiweyo yepolyethylene, engama-25KG/ingxowa;

(2) Gcina umoya ujikeleza kwindawo yokugcina izinto, kuphephe ukukhanya kwelanga ngqo, kwaye ugcine kude nemithombo yomlilo;

(3) Ngenxa yokuba i-hydroxyethyl methyl cellulose HEMC i-hygroscopic, akufuneki ibekwe emoyeni. Iimveliso ezingasetyenziswanga kufuneka zivalwe kwaye zigcinwe, kwaye zikhuselwe kumswakama.
