Indima ye-hydroxypropyl starch ether kudaka

I-akhawunti kawonke-wonke ye-WeChat ityhala rhoqo umxholo okumgangatho ophezulu onjengamava obugcisa, amaxabiso e-cellulose ekrwada, iintsingiselo zemarike, izaphulelo, njl. Silandele!

Intshayelelo ye-Starch Ether

Esona sistatshi sixhaphakileyo nesixhaphakileyo sisitatshi setapile, isitatshi setapioca, isitatshi sombona, isitatshi sengqolowa, kunye nesitatshi secereal esinamafutha aphezulu kunye nomxholo weprotheyini. Iingcambu zestatshi ezifana neetapile kunye netapioca istatshi zisulungekile ngakumbi.

Isitatshi yipolysaccharide macromolecular compound eyenziwe yiglucose. Kukho iintlobo ezimbini zeamolekyu, ezihambelanayo kunye ne-branched, ezibizwa ngokuba yi-amylose (umxholo we-20%) kunye ne-amylopectin (umxholo malunga ne-80%). Ukuze kuphuculwe iimpawu zokusetyenziswa kwesitashi kwizinto zokwakha, inokuguqulwa ngeendlela eziphathekayo kunye neekhemikhali ukwenza iimpawu zayo zifaneleke ngakumbi kwiimfuno zezinto zokwakha ngeenjongo ezahlukeneyo. Hydroxypropyl starch ether

Indima ye-starch ether kumdaka

Kwimeko yangoku yokwandisa indawo yethayile, ukongeza isitashi se-ether kunokuphucula ukuchasana kwe-slip ye-adhesive tile.

iiyure zokuvula ezongeziweyo

Ukufumana i-tile ye-tile, inokuhlangabezana neemfuno ze-adhesives ezikhethekileyo ze-tile (i-Class E, i-20min eyandisiweyo ukuya kwi-30min ukufikelela kwi-0.5MPa) eyandisa ixesha lokuvula.

Iipropati zomphezulu eziphuculweyo

Isitatshi se-ether sinokwenza umphezulu wesiseko segypsum kunye nodaka lwesamente lube lula, ukulusebenzisa lula, kwaye lunesiphumo esihle sokuhombisa. Kunentsingiselo enkulu yokutyabeka udaka kunye nodaka olucekethekileyo lokuhombisa olufana ne-putty.

Indlela yokusebenza yestatshi ether

Xa isitashi se-ether sinyibilika emanzini, siya kusasazwa ngokulinganayo kwinkqubo yodaka lwesamente. Ekubeni i-molecule ye-starch ether inesakhiwo sothungelwano kwaye ihlawuliswe kakubi, iya kuthabatha iincinci zesamente ezihlawulweyo kwaye isebenze njengebhuloho yenguqu ukudibanisa i-samente, ngaloo ndlela inika Ixabiso elikhulu lemveliso ye-slurry inokuphucula i-anti-sag okanye i-anti-anti- isiphumo sokutyibilika.

Umahluko phakathi kwe-starch ether kunye ne-cellulose ether

(1) Isitashi i-ether inokuphucula ngokufanelekileyo ukusebenza kwe-anti-sag kunye ne-anti-slip ye-mortar, ngelixa i-cellulose ether ngokuqhelekileyo inokuphucula kuphela i-viscosity kunye nokugcinwa kwamanzi kwenkqubo kodwa ayikwazi ukuphucula ukusebenza kwe-anti-sag kunye ne-anti-slip.

(2) ukutyeba kunye ne-viscosity

Ngokuqhelekileyo, i-viscosity ye-cellulose ether imalunga namashumi amawaka, ngelixa i-viscosity ye-starch ether ingamakhulu aliqela ukuya kumawaka aliqela, kodwa oku akuthethi ukuba ukujiya kwepropathi ye-starch ether ukuya kudaka ayilunganga njengaleyo ye-cellulose ether, kwaye indlela yokujiya kwezi zibini zahlukile.

(3) Xa kuthelekiswa neselulosi, isitashi se-ether sinokunyusa kakhulu ixabiso lesivuno sokuqala se-adhesive tile, ngaloo ndlela siphucula ukusebenza kwe-anti-slip.

(4) Ukungena emoyeni

I-ether ye-cellulose inepropati eyomeleleyo yokungenisa umoya, ngelixa i-starch ether ingenayo ipropati yokungenisa umoya.

(5) I-cellulose ether isakhiwo semolekyuli

Nangona zombini isitashi kunye ne-cellulose zenziwe ngeamolekyu ze-glucose, iindlela zabo zokuqulunqa zahlukile. Zonke iimolekyuli zeglucose kwistatshi zicwangciswe kwicala elinye, ngelixa i-cellulose ichasene. Zonke ezikufutshane Ukuqhelaniswa kwee-molecule ze-glucose kuchasene, kwaye lo mahluko wesakhiwo uphinda unqume umahluko kwiipropati ze-cellulose kunye nesitashi.

Isiphelo: Xa i-cellulose ether kunye ne-starch ether zisetyenziselwa ukudibanisa, umphumo omuhle we-synergistic ungenzeka. Iimvavanyo zibonise ukuba ukusebenzisa i-ether ye-starch endaweni ye-20% -30% ye-ether cellulose kwi-mortar ayikwazi ukunciphisa umthamo wokugcinwa kwamanzi wenkqubo yodaka, kwaye inokuphucula ngokufanelekileyo i-anti-sag kunye ne-anti-slip nekhono.
