Imboni yezokwakha iye yashintshwa ngokusetshenziswa kwezithasiselo ezihlukahlukene ekukhiqizeni izinto zokwakha ezifana nokhonkolo, usimende nodaka.Esinye sezengezo ezinjalo yi-hydroxypropyl starch ether, evame ukwaziwa ngokuthi i-HPS, esetshenziselwa ukuguqula izakhiwo zodaka.Kulesi sihloko, sizoxoxa ngendima ye-hydroxypropyl starch ether odakeni.
I-Hydroxypropyl starch ether iyimpushana emhlophe noma ekhanyayo ephuzi, encibilika emanzini.Ikhishwa ku-cornstarch ngenqubo yokuguqulwa kwamakhemikhali ehlanganisa i-etherification ne-hydroxypropylation.Isengezo esiwumphumela sithuthukise ukugcinwa kwamanzi, ukucutshungulwa kanye nokuzinza, okwenza abe ekahle ukusetshenziswa odakeni.
Udaka luyingxube yesihlabathi, usimende, amanzi kanye nezithasiselo ezisetshenziselwa ukubamba izinto zokwakha ndawonye.Kunezinzuzo ezimbalwa zokwengeza i-hydroxypropyl starch ether odakeni.Okokuqala, kuthuthukisa ukucutshungulwa kwengxube.Ukusebenza kubhekisela ekuxutshweni kalula kodaka, ukubekwa nokuqedwa.Ngokungezwa kwe-HPS, udaka luba lula ukusabalalisa, okuholela ekumbozeni okungcono kanye nesiphetho esibushelelezi.Lokhu kubaluleke kakhulu ezindaweni lapho ubuhle bubalulekile, njengokuqedwa kokuhlobisa.
Okwesibili, i-hydroxypropyl isitashi ether ithuthukisa ukusebenza kokugcinwa kwamanzi odaka, ngaleyo ndlela yehlise ukulahleka kwamanzi phakathi nenqubo yokwelapha.Amanzi ayingxenye ebalulekile yokumiswa kokuqala kanye nokuqina kodaka.Ngakho-ke, ukugcina amanzi engxube isikhathi eside kuthuthukisa izakhiwo zemishini yodaka olulashiwe.Lokhu futhi kubangela inani elincishisiwe lokuqhekeka futhi kwandisa ukuqina kwayo.
Okwesithathu, i-HPS ithuthukisa izici zokuzinza zodaka.Inciphisa ukuhlukaniswa kwengxube, okwenzeka ngenxa yokuhluka kobukhulu nobukhulu bezingxenye.Lokhu kuvumela ingxube ukuthi ihlale izinzile isikhathi eside ngaphandle kwengozi yokuzinza noma ukuhlangana.Lesi sici siwusizo ikakhulukazi lapho ingxube idinga ukuthuthwa noma ukugcinwa isikhathi eside ngaphambi kokusetshenziswa.
Sengiphetha, i-hydroxypropyl starch ether iyisengezo esibalulekile esingasetshenziswa ukuthuthukisa izakhiwo zemishini nezobuhle zodaka.Ithuthukisa ukucutshungulwa, ukugcinwa kwamanzi kanye nokuzinza, iyenze ilungele onjiniyela nabadwebi bezakhiwo.Ngokunciphisa inani lamanzi alahlekile ngesikhathi sokwelashwa, kwandisa ukuqina namandla odaka olulahliwe, okwenza kube ukukhetha okufanelekile kwezinhlelo zokuthwala umthwalo.Ngaphezu kwalokho, ukucutshungulwa kwengxube kuyathuthukiswa futhi umkhiqizo wokugcina ukhanga kakhulu.Ngakho-ke, ukusetshenziswa kwe-hydroxypropyl starch ethers ekukhiqizeni udaka kuyindlela esebenzayo yezinkampani ezifuna ukuthuthukisa ikhwalithi yemikhiqizo yazo yokugcina.
