Ukusetyenziswa kwesitatshi seEtere kwiiMveliso eziSekwe kwisamente

Isitatshi ether luhlobo lwe-Hydroxypropyl starch ether esetyenziswa ngokubanzi njengesongezo kwiimveliso ezisekelwe kwisamente ezifana nodaka, ikhonkrithi, kunye ne-grouts.Umsebenzi oyintloko we-starch ether kwezi mveliso kukuphucula ukusebenza kwazo, ukugcinwa kwamanzi, kunye neempawu zokubambelela.Ukusetyenziswa kwe-ether yestatshi kwiimveliso ezisekwe kwisamente kunokuchazwa ngolu hlobo lulandelayo:

1. Ukwandiswa kokusebenza: Isitashi i-ether inokuphucula ukusebenza kweemveliso zesamente ngokunciphisa i-viscosity yazo.Oku kuphunyezwa nge-adsorption ye-starch ether molecules phezu kwamasuntswana e-samente, okunciphisa iintlawulo zabo ze-electrostatic kunye nokwandisa ukuhamba kwazo.Oku kuvumela iinqununu zesamente ukuba zihambe ngokukhululekileyo, okubangela ukuba kubekho ulwelo olungaphezulu kwaye kulula ukusebenza ngomxube.
2. Ukugcinwa kwamanzi: Isitashi i-ether inokuphucula ukugcinwa kwamanzi kwiimveliso ezisekelwe kwi-samente ngokwenza ifilimu ekhuselayo malunga neengqungquthela zesamente.Le filimu ithintela amanzi akumxube ukuba aphume ngokukhawuleza, evumela ukuba imveliso esekwe kwisamente ihlale isebenza ixesha elide.Oku kubaluleke kakhulu kwiimeko ezishushu nezomileyo, apho izinga lokunyuka kwamanzi kwimveliso esekwe kwisamente liphezulu.
3. Ukubambelela: Isitashi i-ether inokuphucula ukudibanisa kweemveliso ezisekelwe kwi-samente kwi-substrate ngokunyusa ukunyanzeliswa kwazo.Oku kuphunyezwa ngokuqulunqwa kweebhondi ze-hydrogen phakathi kwe-athomu ye-ether ye-starch kunye ne-substrate surface, eyandisa amandla okunamathela kwi-interfacial.Oku kuphucula amandla okubambisana phakathi kwemveliso ye-samente kunye ne-substrate, ukunciphisa umngcipheko wokuqhawula okanye ukungaphumeleli.
4. Ukuchasana nokuqhekeka: Isitatshi i-ether inokuphucula ukuxhathisa kokuqhekeka kweemveliso ezisekwe kwisamente ngokunyusa amandla azo okuqina.Oku kuphunyezwa ngokuqulunqwa kothungelwano lwe-t-dimensional network ye-starch ether molecules kumxube, osebenza njengento yokuqinisa kwaye inceda ukusabalalisa uxinzelelo lwe-tensile ngakumbi.Oku kunokuphucula ukuqina kunye nexesha elide lemveliso esekwe kwisamente.

Isishwankathelo, ukusetyenziswa kwe-starch ether kwiimveliso ezisekelwe kwi-samente kunokuphucula ukusebenza kwazo, ukugcinwa kwamanzi, ukunamathela, kunye neempawu zokumelana nokuqhekeka.Isitashi i-ether ifezekisa oku ngokunciphisa i-viscosity yomxube, ukwenza ifilimu ekhuselayo malunga neengqungquthela zesamente, ukwandisa ukunyanzeliswa komxube, kunye nokuphucula amandla emveliso.Ukusetyenziswa kwe-starch ether kwiimveliso ezisekelwe kwi-samente kunokuphucula ukusebenza ngokubanzi kunye nokuqina komxube, okukhokelela kwinkqubo yokwakha esebenzayo kunye nesebenzayo.
