Nws lub peev xwm los hloov kho viscosity dhau ntau yam yog qhov tseem ceeb hauv ntau daim ntawv thov, suav nrog ua cov thickener hauv tshuaj pleev ib ce thiab khoom noj khoom haus.
Kev ruaj ntseg
HPS ua qauv qhiazoo heev stabilitynyob rau hauv ntau yam mob, nrog rau qhov kub thiab txias, qhov chaw qis thiab siab pH, thiab muaj cov electrolytes. Qhov kev ruaj ntseg no ua rau nws yog ib tus neeg sib tw zoo tshaj plaws rau kev siv cov khoom noj thiab cov khoom noj uas tsis yog khoom noj uas xav tau lub neej ntev thiab kev ua haujlwm zoo ib yam, xws li hauv tshuaj pleev ib ce thiab tshuaj.
Film-forming thiab khi khoom
Vim nws lub peev xwm los tsim cov yeeb yaj kiab thiab nws cov peev xwm sib txuas, HPS feem ntau yog siv rau hauv cov txheej txheem, cov ntsiav tshuaj formulations, thiab lwm yam khoom uas yuav tsum tau ua tus neeg sawv cev ua yeeb yaj kiab. Nws cov nplaum nplaum thiab cov khoom sib txuas ua rau nws yog qhov kev xaiv nrov rau kev siv hauv cov khoom noj khoom haus, tshuaj ntsiav tshuaj, thiab lwm yam kev siv uas cov yam ntxwv no tseem ceeb.
Non-toxic thiab Biodegradable
HPS feem ntau suav hais tias yognyab xeeb (GRAS)siv rau hauv cov khoom noj khoom haus thiab yogbiodegradable, ua rau nws ib puag ncig tus phooj ywg lwm txoj rau hluavtaws polymers. Cov cuab yeej no pab txhawb rau nws qhov kev thov nce ntxiv hauv cov ntawv thov kom ruaj khov, xws li cov ntim khoom biodegradable thiab ib puag ncig lub luag haujlwm.

Kev siv ntawm Hydroxypropyl Starch Ether
Kev lag luam zaub mov
HPS feem ntau yog siv hauv kev lag luam khoom noj khoom haus raws li athickening tus neeg sawv cev, stabilizer, thiab emulsifier. Nws lub peev xwm los tsim cov kev daws teeb meem ruaj khov thiab khaws cov dej noo ua rau nws zoo tagnrho rau siv hauv cov kua zaub, kua ntses, hnav khaub ncaws, thiab khoom qab zib. Nws kuj tseem siv rau hauv kev tsim cov khoom noj tam sim thiab cov khoom noj ua tiav, qhov uas nws pab txhim kho kev ntxhib los mos thiab txee lub neej. HPS muaj peev xwm tiv thaiv syneresis (kev sib cais ntawm cov kua los ntawm gel) txhim kho qhov zoo thiab sib xws ntawm cov khoom noj khoom haus.
