Ngoku abantu abaninzi abazi kangako malunga ne-hydroxypropy statshi other. Bacinga ukuba akukho mahluko phakathi kwe-hydroxypropy starch ether kunye nesitatshi esiqhelekileyo, kodwa akunjalo. Isixa se-hydroxypropy starch ether esisetyenziselwa iimveliso zobudaka sincinci kakhulu, kwaye inani elongezelelekileyo lePola linokufikelela kwiimpembelelo ezisemgangathweni.
I-Hydroxypropy starch Ether (i-HPS) ngumgubo omhlophe owehle ofunyenwe ngokuguqula izityalo zemvelo, ikhutshiwe, kwaye emva koko atshiswe, ngaphandle kweplasitiza, ngaphandle kweplasitiki. Yahluke ngokupheleleyo kwitatshi eqhelekileyo okanye isitatshi esiguquliweyo.
Kunye ne-hydroxyl i methyl sellise, ekwabizwa ngokuba yi-hypromellose, i-hydroxyllopyl vithan vithamin iyure, kwaye isebenzisa i-° stulose iyure, kwaye ihlukumeza i-cley nge-35 ° C, ukuze i-Polymerizas ye-Polymerization ye-Polymeri I-Alkali Fiber iphakathi koluhlu olufunekayo. Beka i-alkali fiber kwi-etherle, yongeza i-propylene oxide kunye ne-methyl chloride ngokulandelelana, kwaye wazisa nge-50-80 ° C kwiiyure ezi-5, kwaye elona xinzelelo luphezulu malunga ne-1,8MPA. Emva koko yongeza isixa esifanelekileyo se-hydrochloric acid kunye ne-oxcalic acid ukuya kumanzi ashushu kwi-90 ° C ukuhlamba umxholo ukwandisa ivolumu, emva koko inciphise i-centrifuge, kwaye ekugqibeleni yihlambe ngokungathathi cala. Isetyenziswe ngokubanzi ngokwakhiwa, ishishini lekhemikhali, ipeyinti, ishishini, ishishini, ngokulandelelana iarhente yefilimu, ngokulandelelana iarhente yefilimu, i-binder, i-stickener, njl.
I-Hydroxypropy Ether Starch Ether inokusetyenziswa njengengxwabangxwaba yemveliso esekwe kwisamente, iimveliso ezisekwe kwiGypsim kunye neemveliso ze-lime. Ihambelana ngokuchanekileyo nolunye ulwakhiwo. Isetyenziswe kunye ne-hydroxypropyl methylcelcelgalose ether hpmc, inokunciphisa umthamo we-hpmxylcelce
