Uphawu oluphambili lwe-hydroxyethyl methylcellulose

IHydroxyethyl methylcellulose (HEMC) yimveliso eyenziweyo yeselulosi edla ngokusetyenziswa kwiintlobo ngeentlobo zezicelo, njengokutya, kumayeza, nakumashishini okhathalelo lomntu.Ezinye zeempawu eziphambili ze-HEMC ziquka ukunyibilika kwayo okuphezulu kwamanzi, ukukwazi ukujiya kunye nokuzinzisa izisombululo, kunye nokuhambelana kwayo nezinye izithako.

Enye yeempawu eziphambili ze-HEMC kukunyibilika kwayo okuphezulu kwamanzi.Oku kuthetha ukuba inokunyibilika emanzini ngokulula, ivumela ukuba ifakwe ngokulula kwimiqulu efana ne-emulsions, i-gels, kunye nokumiswa.I-HEMC ikwahambelana noluhlu olubanzi lwezinye izithako, nto leyo eyenza ukuba ibe sisithako esisebenzayo sokusetyenziswa kwizicelo ezininzi ezahlukeneyo.

Olunye uphawu olubalulekileyo lwe-HEMC kukukwazi ukujiya kunye nokuzinzisa izisombululo.I-HEMC ine-viscosity ephezulu, oku kuthetha ukuba inokongeza ubukhulu kunye nomzimba kwizisombululo.Oku kunokuba luncedo ngakumbi kwiimveliso ezinje ngeekhrimu kunye neloshini, apho kufunwa ukutyeba, ukuthungwa okugudileyo.I-HEMC inokunceda ukuzinzisa i-emulsions kunye nokumiswa, ukuthintela ukuba bahlukane ngokuhamba kwexesha.

I-HEMC yaziwa ngeempawu zayo ezintle zokwenza ifilimu.Oku kuthetha ukuba inokwenza ifilimu eqinile, eguquguqukayo ebusweni bezinto eziphathekayo, ezinokukunceda ukukhusela kumonakalo okanye ukuthotywa.Le propati yenza i-HEMC ibe sisithako esithandwayo kwiingubo kunye neefilimu kwiintlobo ezahlukeneyo zezicelo.

Ukongeza kwezi zakhiwo, i-HEMC nayo i-biocompatible kunye ne-non-toxic, eyenza ikhuseleke ukusetyenziswa kwizicelo ezininzi ezahlukeneyo.Ikwachasene nokukhula kwe-microbial, okunceda ukwandisa ubomi beshelufu yeemveliso eziqukethe i-HEMC.

Ngokubanzi, iimpawu eziphambili ze-hydroxyethyl methylcellulose zenza ukuba ibe yinto edibeneyo kwaye iluncedo kuluhlu olubanzi lwezicelo.Ukunyibilika kwayo okuphezulu kwamanzi, ukukwazi ukujiyisa kunye nokuzinzisa izisombululo, iipropati zokwenza ifilimu, kunye nokuhambelana nezinye izithako zenza kube yinto ethandwayo yokusetyenziswa kwiimveliso ezahlukeneyo, ukusuka kwizinto zokuthambisa ukuya kwiimveliso zamayeza kwiimveliso zokutya.
