Njengezinto ezisetyenziswa rhoqo kumashishini ahlukeneyo, i-Ether Ether Ether inomgubo ogqwesileyo, ukuqina nokugcinwa kwamanzi. Isetyenziswe ngokubanzi ngokwakhiwa, amayeza, amayeza, ukutya, ukutya kunye nezinye iinkalo ezininzi. Nangona kunjalo, ukufumana eyona ntsebenzo ilungileyo evela kwi-selsulose ether, ingqalelo kufuneka ihlawulwe kwinkqubo yayo yokuchitha. Nazi ezinye izinto eziphambili ekufuneka ziqwalaselwe xa inyibilikisa i-ether ye-ether ether:
1. Khetha isolvent elungileyo
I-Selese i-ether powder inyibilikihla emanzini, yenza isisombululo esibonakalayo, i-viscous. Nangona kunjalo, iintlobo ezahlukeneyo zeselpulose Tallise inesifo esahlukileyo emanzini, kwaye ukuluka kwabo kuya kuchaphazeleka ngezinto ezinje ngobushushu kunye ne-pH. Ke ngoko, ukukhetha isoyile sasekunene kwiziphumo ezigqibeleleyo kubalulekile.
Umzekelo, ukuba i-Ethem i-Ether i-Ether Powder kufuneka ichithwe kwimo yeqondo lobushushu ephantsi okanye kwinkqubo ephantsi ye-PH, i-HCDROXYPOPYLMUTHLTETHLTELCETLCETLCETLCETLOSE (MC) Kubalulekile ukukhetha isisweli esifanelekileyo ekuqwalaseni iimfuno zesicelo kunye neepropathi zesinyibilikisi.
2. Iqondo lobushushu
Iqondo lokushisa yenye into ephambili echaphazela ukupheliswa kwe-gather ether ither. Ukunyibilisela kweeselsese Teluplose Talupes kunyusa ubushushu, kodwa ke ngoko ireyithi yokutshitshiswa, enokukhokelela kwimida ye-Ageglomed okanye iAggomed. Ke ngoko, iqondo lobushushu kufuneka lilawulwe ngononophelo ngexesha lenkqubo yokuphelisa.
Ngokubanzi, amaqondo obushushu aphezulu kwi-Ether Seleese i-Ether yi-20-40 ° C. Ukuba iqondo lobushushu liphantsi kakhulu, kunokuba yimfuneko ukwandisa ixesha lokutshabalala okanye ukusebenzisa i-Solvent efanelekileyo. Ukuba iqondo lobushushu liphezulu kakhulu, linokubangela ukonakaliswa kwe-sellyulose ether kwaye kuchaphazela intsebenzo yayo.
3. Suma kwaye uvuse
Ukuvuselela kunye nokuphazamiseka kubalulekile xa inyibilikisi i-Ether Ether. Uxinzelelo olufanelekileyo lunceda umgubo wokusasaza ngokulinganayo kwi-solvent kwaye ithintela ukuncama. Ukuvuselela kwakhona kuyanceda ukwandisa inqanaba lokupheliswa, ngakumbi kwizisombululo ze-viscofity ephezulu.
Nangona kunjalo, ukuphazamiseka okugqithisileyo kunokuvelisa iiblubhu zomoya okanye i-foam, enokuchaphazela ukucaciswa kunye nokuzinza kwesisombululo. Ke ngoko, kuyimfuneko ukuba uhlengahlengise isantya kunye nobunzulu bokuqina ngokweemfuno ezithile kunye nendawo yokufaka isicelo se-selsulose ether.
I-4. Izongezo
Izongezo zinokongezwa ngexesha lokuchithwa kwe-selsuse ether i-ether yokuphucula ukusebenza okanye uzinzo. Umzekelo, i-borax okanye ezinye izinto ze-alkaline zinokongezwa ukuze zilungelelanise i-Ph yesisombululo kwaye zandise i-viscofity. I-sodium Bicarbonate nayo yonyusa i-viscomosity yesisombululo, icothise ireyithi yento yokupheliswa.
Ezinye iizongezo ezifana ne-surfacapes, iityuwa okanye iibhlomers zinokusetyenziselwa ukomeleza, uzinzo okanye ezinye iipropathi zesisombululo se-Selese. Nangona kunjalo, kubalulekile ukusebenzisa izongezo ngokumodareyitha kwaye ukhethe ngononophelo, njengokuba oolongezo bangaphezulu okanye abangafanelekanga kunokubangela iziphumo ebezingafuneki.
I-5. Ukuchitha ixesha
Ixesha lokuchithwa yiparamitha elibalulekileyo kwimveliso kunye nokusetyenziswa kwe-selsulose ether. Ixesha lokuphelisa lixhomekeke kwizinto ezininzi ezinje ngohlobo lwe-selsulose ether, isinyibiliki, ubushushu, isantya kunye nokugxininisa.
Ngokubanzi, i-Ether Ither Powder kufuneka yongezwe kwi-solvent kancinci kwaye ngokuthe ngcembe ngokuxuba rhoqo de kube kufunyenwe isisombululo sehomogeneous. Amaxesha okuhlaziya angahluka kwimizuzu embalwa ukuya kwiiyure ezininzi, kuxhomekeke kwizinto ezichazwe apha ngasentla.
Kubalulekile ukuba ujonge inkqubo yokuchitheka kunye nokuhlengahlengisa iiparamitha njengoko kufuneka ukuze kuqinisekiswe umgangatho kunye nokungaguquguquki kwesisombululo se-Selese.
Ukuqukumbela, i-Sethel Ether i-Ether Powder yindawo ebonakalayo kunye nezinto ezixabisekileyo kwimimandla eyahlukeneyo yeshishini. Nangona kunjalo, inkqubo yokuphelisa kubalulekile ukufezekisa intsebenzo yayo efanelekileyo. Ngokunikela ingqalelo kwizinto ezinje ngokusekwa kweSolvent, ukulawula ubushushu, ukushukumisa, ii-conses, kunye nexesha lokutshabalalisa, kunokwenzeka ukuba ufumane i-ETE ETEROSE ETEROSE ehlangabezana neemfuno zesicelo.
