Ingxoxo ngeMpembelelo yokongezwa kweHydroxypropyl Methyl Cellulose kwiiPropati zoMdaka.

IHydroxypropyl methylcellulose HPMC inokuphucula kakhulu ukugcinwa kwamanzi odaka.Idosi esezantsi ye-hydroxypropyl methylcellulose HPMC inokuphucula kakhulu izinga lokugcinwa kwamanzi kwidaka.Xa idosi yi-0.02%, izinga lokugcinwa kwamanzi liyenyuka ukusuka kwi-83% yenyuka ukuya kwi-88%;xa idosi yayiyi-0.2%, izinga lokugcinwa kwamanzi lafikelela kuma-97%.Kwangaxeshanye, umxholo ophantsi HPMC kwakhona kakhulu kunciphisa iqondo delamination kunye nesantya ukopha kodaka, nto leyo ebonisa ukuba HPMC ayikwazi nje ukuphucula ukugcinwa kwamanzi udaka, kodwa kakhulu ukuphucula ukudityaniswa kodaka, leyo kubalulekile ukufana komgangatho wokwakha udaka.ithandeka kakhulu.

Nangona kunjalo, i-hydroxypropyl methylcellulose HPMC inezinga elithile leempembelelo ezimbi kumandla aguquguqukayo kunye namandla oxinzelelo odaka.Ngokunyuka komxholo we-hydroxypropyl methylcellulose HPMC, amandla okuguquguquka kunye namandla oxinzelelo omdaka ancipha kancinci.Kwangaxeshanye, i-hydroxypropyl methylcellulose HPMC inokunyusa amandla okuqina odaka.Xa umxholo we-hydroxypropyl methylcellulose HPMC ungaphakathi kwe-0.1%, amandla okuqina omdaka akhula ngokuqhubekayo kunye nokunyuka komxholo we-HPMC, ngelixa xa umxholo udlula i-0.1%, amandla e-tensile akayi kuphinda anyuke kakhulu.IHydroxypropyl methylcellulose HPMC inokonyusa kakhulu amandla ebhondi yokucheba yodaka.Ukongeza i-0.2% ye-HPMC ingenza amandla ebhondi yodaka ukusuka kwi-0.72MPa yanda ukuya kwi-1.16MPa.

Uphononongo lubonise ukuba i-hydroxypropyl methylcellulose HPMC inokwandisa kakhulu ixesha lokupholisa lodaka kwaye inciphise kakhulu ukutyibilika kodaka, oluncedo kakhulu kulwakhiwo lwe-tile yokunamathisela.Xa i-HPMC ingongezwa, amandla ebhondi yodaka olupholileyo lwemizuzu engama-20 ayancipha ukusuka kwi-0.72MPa ukuya kwi-0.54MPa.Emva kokongeza i-0.05% kunye ne-0.1% ye-HPMC, amandla ebhondi yodaka olupholileyo imizuzu engama-20 yi-0.8MPa kunye ne-0.84MPa, ngokulandelanayo.Xa i-HPMC ingadityaniswanga, ukutyibilika kodaka yi-5.5mm.Ngokunyuka komxholo we-HPMC, i-slippage iyancipha ngokuqhubekayo.Xa umxholo u-0.2%, i-slippage ye-mortar iyancipha ukuya kwi-2.1mm, kwaye i-slippage iyancipha kakhulu.Kwaye olunye ulwakhiwo oluncinci lubonelela ngenkxaso yobugcisa.

Ukongeza, i-hydroxypropyl methylcellulose HPMC inokuthintela ngokufanelekileyo ukubunjwa kweentanda zeplastiki kudaka kwaye inciphise kakhulu iintanda zeplastiki.Xa umxholo we-HPMC uphantsi, i-crack index iyancipha kakhulu ngokunyuka komxholo we-HPMC.Xa umxholo we-HPMC yi-0.1% kunye ne-0.2%, isalathisi sokuqhekeka kwe-mortar yi-63% kunye ne-50%, ngokulandelanayo.Emva kokuba umxholo we-HPMC udlula i-0.2%, Iintanda zeplastiki zodaka azisancitshiswa kakhulu.
