Ukuba nje inani elifanelekileyo le-HPMC ye-cellulose ether yokutya ekumgangatho wokutya yongezwa kukutya okuthosiweyo, ukungenisa ioyile kwinkqubo yokuqhotsa kungancitshiswa kakhulu, umxholo weoyile iyonke yokutya okuthosiweyo ungancitshiswa, kwaye incasa yemveliso ethosiweyo ingaphuculwa, umjikelo wokutshintsha ioyile yokutya okuthosiweyo ungandiswa, isivuno semveliso ethosiweyo singanyuswa kwaye ixabiso leoyile lingancitshiswa.
Ukutya okuqhotsiweyo kuthandwa kakhulu luluntu ngenxa yencasa yako eyahlukileyo. Nangona kunjalo, kwindlela yokutya okunempilo ngakumbi namhlanje, ukutya okuqhotsiweyo okunamafutha amaninzi kwenza abathengi baqaphele.
Kakade ke, xa kusetyenziswa i-cellulose ether nganye, izongezo zokutya zinokufezekisa umsebenzi omnye kuphela, umzekelo, i-methylcellulose (MC) kunye ne-hydroxypropyl methylcellulose (HPMC) zinokunciphisa ngempumelelo umxholo weoyile yokutya okuthosiweyo; i-carboxymethyl cellulose (CMC) yokutya, esetyenziswa kwiimveliso zobisi, inokuphucula incasa kwaye iphucule uzinzo lweproteni, esetyenziswa kwinkqubo yokubhaka, inokulawula ngempumelelo umxholo wamanzi entlama; i-hydroxypropyl cellulose (HPC) yokutya inokunciphisa ngempumelelo ubungakanani bekhrimu yendalo kwifomyula, ngelixa igcina incasa ethambileyo nethambileyo, kwaye iqonde ingcamango yokutya okunempilo.
Ii-ether derivatives ze-cellulose zisetyenziswa kakhulu kwishishini lokutya ixesha elide. Ukuguqulwa kwe-cellulose ngokwasemzimbeni kunokulawula iipropati ze-rheological, ukufuma kunye neepropati ze-microstructure zenkqubo. Imisebenzi emihlanu ebalulekileyo ye-cellulose eguqulwe ngamakhemikhali ekutyeni yi-rheology, i-emulsification, ukuzinza kwe-foam, ukukwazi ukulawula ukwakheka kunye nokukhula kwekristale yomkhenkce, kunye nokubopha amanzi.
Nceda iteknoloji yenyama yokwenziwa yehlabathi engaphezulu kwama-20 ukwenza inkxaso yobugcisa. Uluhlu lweemarike zesitokhwe zase-US lujolise kakhulu kwiincasa zaseMelika naseYurophu. Ingcinga ngokuyintloko kukusebenzisa i-capsule yezityalo eqhelekileyo, iqela lidibanisana. Kwikota yokuqala yonyaka ophelileyo, benze inguqulelo yobuxoki yenyama yokwenziwa. Sizama ukutshintsha ukusuka ekuveliseni i-vector kwilebhu. Okwangoku, inyama yokwenziwa yangaphandle yi-140-150,000 yuan/ton, kodwa ixabiso liphantsi kakhulu. Inkampani iza kwenza imali kwi-cellulosic ether kuqala, kwaye ixhalabele ngemali kwinyama yokwenziwa kamva. Eyona nxalenye inzima yenyama yokwenziwa yi-cellulose, kwaye kwi-DuPont cellulose ether yindawo yokunamathela. Le nkampani ithengisa iitoni ezingama-70,000 ukuya kuma-80,000, ikwanayo ne-60% yemali engenayo. Izixhobo zamva nje neziphucukileyo, izixhobo zeDow's kunye neShin-etsu zineminyaka engama-20 okanye engama-20 ubudala, zithengwe kumthengisi wezixhobo eJamani. Ifomyula eyintloko yenyama yokwenziwa ibalulekile.
