Thaum dissolving ib qho khoom hauv dej, nws yog ib qho tseem ceeb kom xav txog kev kho cov khoom saum npoo av uas cov khoom tau dhau los. Thaum kev kho sab saum npoo av yuav zoo li nthuav dav me me, nws muaj peev xwm cuam tshuam zoo heev rau cov khoom siv solubility hauv dej txias. Qhov tseeb, cov khoom lag luam tsis muaj kev kho deg (tshwj tsis yog hydroxyethyl cellulose) yuav tsum tsis txhob yaj ncaj qha rau hauv dej txias.
Qhov laj thawj yog yooj yim: tsis tau kho cov khoom lag luam zoo li muaj cov chaw hydrophobic. Hauv lwm lo lus, lawv tsis sib tov nrog dej. Thaum cov khoom no tuaj rau hauv kev sib cuag nrog dej, lawv zoo li txhaws ua ke thiab tsim cov pob txha caj dab lossis cov kua txiv es tsis muaj tusyees dissolving. Qhov no tuaj yeem ua rau nws nyuaj kom ua tiav qhov kev xav tau sib xws los yog kev ntxhib los mos ntawm cov khoom kawg.
Txhawm rau zam cov teeb meem no, nws yog ib qho tseem ceeb uas yuav tau ua cov kauj ruam kom yaj hauv dej txias. Ib txoj kev sib txawv yog thawj zaug ua ib qho slurry lossis muab tshuaj txhuam los ntawm kev sib xyaw cov khoom nrog dej sov me ntsis. Qhov no yuav pab tawg ntawm cov khoom kom nruj ntawm cov khoom lag luam thiab tsim muaj ntau homogeneous sib tov. Thaum ib qho slurry yog tsim, nws tuaj yeem maj mam ntxiv rau dej txias thiab sib xyaw kom txog thaum qhov xav tau ua tiav.
Lwm qhov kev xaiv yog siv cov kuab tshuaj lossis surfactant los pab txhim kho kev txhim kho solubility hauv dej txias. Cov tshuaj no tuaj yeem pab rhuav tshem cov khoom kom nruj ntawm cov khoom lag luam thiab tsim cov homogogeneous ntau dua thaum ntxiv rau dej txias. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias tsis yog txhua cov khoom lag luam tau sib xws nrog cov tshuaj sib xyaw lossis surfactants, yog li nws yog ib qho yog rau cov khoom ntawm tes.
Tus yuam sij kom ua tiav cov khoom lag luam hauv dej txias yog ua siab ntev thiab cov qauv hauv cov txheej txheem. Los ntawm kev siv sijhawm sib xyaw thiab yaj cov khoom kom raug, koj tuaj yeem ua tiav qhov xav tau yam thiab kev ntxhib los mos ntawm koj cov khoom kawg.
Thaum nws yuav zoo li yog nthuav dav me me, kev kho mob saum npoo ntawm cov khoom tuaj yeem cuam tshuam ntau rau nws cov solubility hauv dej txias. Cov khoom lag luam tsis muaj kev kho mob saum npoo (tshwj tsis yog hydroxyethyl cellulose) yuav tsum tsis txhob ncaj qha yaj hauv dej txias. Txhawm rau kom koj cov khoom dissolves kom yog, nws yog ib qho tseem ceeb uas yuav tsum tau ua cov kauj ruam tsim nyog los tsim cov slurry lossis muab tso ua ntej ntxiv rau dej txias. Nrog kev ua siab ntev me ntsis thiab kev saib xyuas, koj tuaj yeem ua tiav qhov zoo tshaj plaws kev sib xws thiab kev ntxhib los mos rau koj cov khoom kawg.
