Isakhiwo samangqamuzana:

Izici Zomkhiqizo:

1. Ukubukeka: I-HEMC imhlophe noma cishe impushana emhlophe; ayinaphunga futhi ayinambitheki.

2. Ukunyibilika: Uhlobo H ku-HEMC lungancibilika emanzini angaphansi kuka-60℃, futhi uhlobo lwe-L lungancibilika kuphela emanzini abandayo. I-HEMC iyafana ne-HPMC futhi ayincibiliki kuzincibilikisi eziningi eziphilayo. Ngemuva kokwelashwa okungaphezulu, i-HEMC ihlakazeka emanzini abandayo ngaphandle kwe-agglomeration futhi incibilika kancane, kodwa ingaqedwa ngokushesha ngokulungisa inani layo le-PH libe ngu-8-10.

3. Ukuqina kwenani le-PH: I-viscosity ishintsha kancane phakathi kwebanga elingu-2-12, futhi i-viscosity yonakaliswa ngale kwalolu bubanzi.

4. Fineness: izinga lokuphasa lika-80 mesh liyi-100%; izinga lokuphasa lika-100 mesh ngu-≥99.5%.

5. Amandla adonsela phansi aqondile angamanga: 0.27-0.60g/cm3.

6. Izinga lokushisa lokubola lingaphezu kuka-200℃, futhi liqala ukuvutha ku-360℃.

7. I-HEMC inokuqina okuphawulekayo, ukuzinza kokumiswa, ukuhlakazeka, ukubumbana, ukubunjwa, ukugcinwa kwamanzi nezinye izici.

8. Ngenxa yokuthi umkhiqizo uqukethe iqembu le-hydroxyethyl, izinga lokushisa lejeli lomkhiqizo lifinyelela ku-60-90℃. Ngaphezu kwalokho, iqembu le-hydroxyethyl line-hydrophilicity ephezulu, okwenza futhi izinga eliboshiwe lomkhiqizo libe lihle. Ikakhulukazi ekwakhiweni kokushisa okushisayo nokuphezulu ehlobo, i-HEMC inokugcinwa kwamanzi okuphezulu kune-methyl cellulose ye-viscosity efanayo, futhi izinga lokugcinwa kwamanzi alikho ngaphansi kwama-85%.

Ibanga lemikhiqizo

Ukubaluleka

Njenge-ejenti esebenzayo engaphezulu, i-hydroxyethyl methyl cellulose HEMC inezici ezilandelayo ngaphezu kokuqina, ukumisa, ukubopha, ukufaka ifilimu, ukwenza ifilimu, ukuhlakazeka, ukugcina amanzi kanye nokuhlinzeka ngama-colloid avikelayo:

(1) I-Hydroxyethyl methyl cellulose I-HEMC inyibilika emanzini ashisayo noma abandayo, okwenza ibe nezici ezihlukahlukene zokuncibilika kanye nezici ze-viscosity, okungukuthi, i-gelation engashisi;

(2) I-Hydroxyethyl methyl cellulose I-HEMC ingabambisana nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants, nosawoti, futhi iyi-thickener enhle kakhulu yezixazululo ze-electrolyte eziphezulu zokugxila;

(3) I-HEMC inokugcinwa kwamanzi okunamandla kune-methyl cellulose, futhi ukuzinza kwayo kwe-viscosity, i-dispersibility, kanye nokumelana nesikhutha kunamandla kune-hydroxyethyl cellulose.

Indlela yokulungiselela isixazululo

(1) Faka inani elithile lamanzi ahlanzekile esitsheni;

(2) Engeza i-hydroxyethyl methyl cellulose HEMC ngaphansi kokuvuselela isivinini esiphansi, futhi ugovuze kuze kube yilapho yonke i-hydroxyethyl methyl cellulose incibilika ngokulinganayo;

(3) Ngokubuka idatha yethu yokuhlolwa kobuchwepheshe, kunconywa kakhulu ukuthi uyengeze ngemva kokwengezwa kwe-polymer emulsion (okungukuthi, i-hydroxyethyl methyl celluloseI-HEMCixutshwe ngaphambili ne-ethylene glycol noma i-propylene glycol).

Usiminyaka yobudala

Ezimboniniisakhiwoizinto zokwakha,ukwakhiwa kwebanga le-HEMCkufanelekileizinto zokunamathisela zamathayela, izikhonkwane zikasimende, udaka olomile oluxubile, ukuzilinganisa, ukhonkolo lwegypsum,upende we-latex, izibophezelo zempahla yokwakha, ezinye izinkundla zokwakha, ukumba inkundla kawoyela, imikhiqizo yokunakekela abantu, ama-ejenti okuhlanza, njll., ngokuvamile asetshenziswa njengama-thickeners, ama-protective agents, ama-adhesives, ama-stabilizers, nama-agent amisayo angasetshenziswa futhi njengamajeli e-hydrophilic, izinto ze-matrix. , ukulungisa amalungiselelo okukhululwa okuqhubekayo kohlobo lwe-matrix, futhi kungasetshenziswa njengeziqinisi ekudleni, njll. umphumela.

Packaging kanye nesitoreji

(1) Ipakishwe esikhwameni se-polyethylene esiyinhlanganisela yephepha-plastic noma isikhwama sephepha, 25KG/isikhwama;

(2) Gcina umoya ugeleza endaweni yokugcina, gwema ukukhanya kwelanga, futhi ugweme imithombo yomlilo;

(3) Ngenxa yokuthi i-hydroxyethyl methyl cellulose HEMC i-hygroscopic, akufanele ivezwe emoyeni. Imikhiqizo engasetshenziswanga kufanele ivalwe futhi igcinwe, futhi ivikelwe emswakama.
