I-CMC isebenzisa kuShishino lweepeyinti kunye noKutyabeka

Peyinta umgangatho we-carboxymethyl cellulose sodiumuye ukutyeba okulungileyo, ukusabalalisa kunye nokuzinza, kunokuphucula i-viscosity kunye ne-rheology yeengubo, ngoko ke isetyenziswa ngokubanzi kwiingubo ezahlukeneyo, iingubo ze-latex, i-external based based and internal coatings, i-casting coatings kunye nokunye.

Ukusetyenziswa kwangokoipeyinti Umgangatho we-carboxymethyl cellulose:

Isisombululo esibizwa ngokuba yisisombululo esikhawulezileyo sithetha ukuba umgubo we-CMC unokuchithwa kwaye unyibilike ngokukhawuleza kwisisombululo esimanzi kwiqondo lokushisa eliqhelekileyo, elihluke kuhlobo oluqhelekileyo lweCMC echithwa kancinci (uhlobo oluqhelekileyo lweCMC ludinga ubuncinane iiyure ezingama-2-3 eziphezulu- isantya sokuvuselela ukuba sinyibilike ngokupheleleyo).I-viscosity yebakala lokugquma i-carboxymethyl cellulose ye-CMC ayiyi kufikelela ngokukhawuleza i-viscosity yayo yokwenene kunye nokuchithwa ngokukhawuleza kwepowder, kwaye iya kuba kwimizuzu eyi-10-15 emva kokuchithwa kwe-viscosity, ukubunjwa kwe-viscosity yangempela kunokufezekisa i-colloid. .Ukongeza, uzinzo lwe-colloid lwe-CMC ekhawulezileyo lungcono kunolo lwe-CMC yesiqhelo eneenkcukacha ezifanayo.

Ngoko nangokoenyibilikayoI-carboxymethyl cellulose CMC isetyenziswa ngokubanzi kuzo zonke iintlobo zokugquma kwamanzi, njenge-latex emhlophe, ipeyinti ye-latex, i-putty, ipeyinti yokukhulula, ipeyinti yamatye yendalo, njl.

Izinto ezilungileyo zeipeyinti Umgangatho we-carboxymethyl cellulose:

A) I-Coating ayinamaleko kwaye ingagcinwa ixesha elide;

B) Inokubonelela ngokukhawuleza-ukuchithwa kweemveliso ezikhethekileyo zokugqoka izicelo kwiinkalo ezikhethekileyo;

C) Ukulungelelanisa ngokufanelekileyo i-rheology ye-glaze slurry, uququzelele ukusetyenziswa kwe-glaze, kwaye wenze i-glaze slurry kwisimo esizinzile sokusasazeka;

D) Ukuphucula ngokufanelekileyo amandla e-glaze kunye nokugudiswa kokuthintela ukubola;

E) Qinisekisa inkqubo yokushicilela kwimveliso ye-glaze yokushicilela, kwaye iipatheni eziprintiweyo zicacile kwaye zihle;

F) Akusayi kubakho kuthintela kwinkqubo yoshicilelo lwe-glaze, i-CMC inokunyibilika kakuhle kwamanzi kwaye phantse akukho zinto zinganyibilikiyo ezifana nokungcola kwefayibha;

Peyinta ibakalaCMCIndlela yokuchithwa kwe-carboxymethyl cellulose:

Iipeyinti grade carboxymethyl cellulose ixutywe ngokuthe ngqo namanzi kwaye ilungiswe kwiglue yokuncamathisela ukusetyenziswa kamva.Inqanaba kuqwalaselo lokuncamathelisa i-carboxymethyl cellulose incamathisela yokuncamathelisa, okokuqala ngokuxuba izithako zesityalo kwisilinda ukudibanisa umlinganiselo othile wamanzi acocekileyo, kwindawo evulekileyo phantsi kwemeko yesixhobo esishukumisayo, inqanaba lokugquma le-carboxymethyl cellulose ngokucotha nangokulinganayo kwizithako ezikwisilinda. , ukuvuselela rhoqo, ukwenza ipeyinti ye-carboxymethyl cellulose kunye ne-fusion yezinga lamanzi, i-carboxymethyl cellulose inokunyibilika ngokupheleleyo inqanaba lokugquma.Xa unyibilika ipeyintiibakala I-carboxymethyl cellulose, isizathu sokusasazeka ngokulinganayo, kwaye rhoqo ivuselela, injongo "kukuthintela ibakala lokupeyinta i-carboxymethyl fiber kunye namanzi adibane, i-agglomeration, i-agglomeration, ukunciphisa ibakala lokupeyinta ingxaki yokunyibilika kwe-carboxymethyl cellulose", kunye nokuphucula izinga lokuchithwa kwebanga lepeyinti ye-carboxymethyl. iselulosi.Ixesha lokuvuselela kunye nebakala lokupeyinta i-carboxymethyl cellulose epheleleyo ixesha lokuchithwa alihambelani, zimbini iikhonsepthi, ukuthetha ngokubanzi, ixesha lokuvuselela lifutshane kakhulu kunebakala lokupeyinta i-carboxymethyl cellulose epheleleyo ixesha lokuchithwa, ixesha elifunekayo lixhomekeke kwimeko ethile.

Ukumisela ixesha lokuvuselela ngesiseko: xa i-carboxymethyl cellulose emanzini ihlakazekile ngokulinganayo, akukho nto icacileyo yeqhuma elikhulu, unokuyeka ukuvuselela, ukuze i-carboxymethyl cellulose kunye namanzi kwindawo e-static yokungena ngokubambisana, ukudibanisa.

Ukumisela i-carboxymethyl cellulose ukupheliswa ngokupheleleyo kwexesha elifunekayo ngokwezi nkalo zilandelayo:

(1) ibakala lokupeyintaCMCI-carboxymethyl cellulose kunye namanzi ziboshwe ngokupheleleyo, kwaye akukho kwahlukana okuqinileyo-olwelo phakathi kwabo;

(2) Intlama edibeneyo ikwimeko efanayo, kwaye umphezulu ugudile;

(3) Umbala we-aleurone edibeneyo usondele kumbala kunye nokungafihli, kwaye akukho nto i-granular kwi-aleurone.Ukususela kwibakala lokupeyintaCMCI-carboxymethyl cellulose ifakwe kwitanki yokuxuba ngamanzi, ukuya kwibakala lokupeyintaCMCI-carboxymethyl cellulose ichithwe ngokupheleleyo, ixesha elifunekayo phakathi kwe-10 ukuya kwiiyure ze-20.
