IHydroxyethyl methylcellulose (HEMC) yipolymer esetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, izinto zokuthambisa, kunye nokwakha. Iyaxatyiswa ngokutyeba kwayo, ukumilisela, ukwenza ifilim, kunye neempawu zayo zokuzinzisa. Ngaphandle kokusetyenziswa kwayo ngokubanzi, ukuqinisekisa ukhuseleko ngexesha lokuphatha nokusetyenziswa kwayo kubalulekile. Nazi izilumkiso ezibanzi zokhuseleko xa usebenzisa i-hydroxyethyl methylcellulose:
1. Ukuqonda Umbandela
I-HEMC yi-ether ye-cellulose engekho i-ionic, i-derivative ye-cellulose apho amaqela e-hydroxyl athatyathelwe indawo nge-hydroxyethyl kunye namaqela e-methyl. Olu hlengahlengiso luphucula ukunyibilika kwayo kunye nokusebenza kwayo. Ukwazi iimpawu zayo zemichiza nezomzimba, njengokunyibilika, i-viscosity, kunye nokuzinza, kunceda ekuyiphatheni ngokukhuselekileyo.

6. Iingozi zeMpilo kunye nemilinganiselo yoNcedo lokuQala
Ukuphefumla:
Ukuvezwa ixesha elide kuthuli lwe-HEMC kunokubangela ukucaphuka kokuphefumula.
Hambisa umntu ochaphazelekayo emoyeni omtsha kwaye ufune unyango ukuba iimpawu ziyaqhubeka.
UQhagamshelwano loLusu:
Geza indawo echaphazelekayo ngesepha kunye namanzi.
Funa icebiso likagqirha xa ucaphuka.
Uqhagamshelo lamehlo:
Hlamba amehlo kakuhle ngamanzi ubuncinane imizuzu eyi-15.
Susa iilensi zoqhagamshelwano ukuba zikhona kwaye kulula ukuzenza.
Funa unyango ukuba ucaphuka uyazingisa.
Ukungeniswa:
Hlamba umlomo ngamanzi.
Musa ukukugabha ngaphandle kokuba uyalelwe ngabasebenzi bezonyango.
Funa uncedo lwezonyango ukuba utyiwe kakhulu.
7. Iingozi zoMlilo kunye nokuqhushumba
I-HEMC ayinakutsha kakhulu kodwa inokutsha xa ibekwe emlilweni.
Amanyathelo okulwa noMlilo:
Sebenzisa isitshizi samanzi, ugwebu, imichiza eyomileyo, okanye ikharbon diokside ukucima imililo.
Gqoka izixhobo ezipheleleyo zokukhusela, kubandakanywa nezixhobo zokuphefumla ezizimeleyo (SCBA), xa ulwa nomlilo obandakanya i-HEMC.
