I-hypromellose ecocekileyoHPMCibukeka iguquguquka kunye noxinano lwesambuku esincinci ukusuka kwi-0.3 ukuya kwi-0.4 ml, ngelixa i-HPMC edibeneyo ishukumayo, inzima kwaye yahlukile kwimveliso yokwenyani ngenkangeleko. Isisombululo samanzi se-hypromellose se-HPMC esicocekileyo sicacile kwaye sinokugqithisela ukukhanya okuphezulu, kwaye izinga lokugcinwa kwamanzi lingaphantsi kwe-97%, ngelixa isisombululo se-HPMC esixutywe ngamanzi sine-turbid, kwaye izinga lokugcinwa kwamanzi akunakukwazi ukufikelela kwi-80%. Unyuluhypromellose HPMCakufuneki ukuba ivumba ammonia, istatshi kunye notywala, lo gama uphingeHPMCithande ukunuka iintlobo ngeentlobo zamavumba kwaye uzive unzima. I-hypromellose HPMC powders esulungekileyo ine-fibrous phantsi kweglasi yokukhulisa, ngelixa i-HPMC powders egqwethiweyo iluqilima okanye iikristale.
I-Hydroxypropylmethylcellulose yinto eyongeziweyo yezinto zokwakha eziqhelekileyo ekusebenziseni izinto zokwakha, ezisetyenziswa kakhulu kwishishini kunye neentlobo ezahlukeneyo. IHydroxypropyl methyl cellulose inokohlulwa ibe ngamanzi abandayo ohlobo lwangoko nangoko kunye nohlobo lokunyibilika okushushu.
Amanzi abandayo anyibilikayo HPMC ingasetyenziselwa umgubo putty, udaka, iglu engamanzi, ukutyabeka elulwelo, kunye neemveliso imichiza mihla. I-Hot melt HPMC idla ngokusetyenziselwa iimveliso zomgubo owomileyo kwaye ixutywe ngokuthe ngqo nomgubo owomileyo ukuze wenze isicelo esifanayo, esifana nomgubo weputty kunye nodaka. I-Hydroxypropylmethylcellulose ingasetyenziselwa ngokubanzi ukuphucula ukusebenza kwezinto zokwakha ze-hydrate ezifana ne-samente kunye ne-gypsum. Kudaka olusekwe kwisamente, ukugcinwa kwamanzi kunokuphuculwa, ixesha lokulinganisa kunye nexesha lokuvula linokwandiswa, kunye nokumiswa kokuhamba kungancitshiswa.
I-Hydroxypropylmethylcellulose ingasetyenziselwa ukuxuba izinto zokwakha kunye nezakhiwo, kwaye iifomyula zokuxuba ezomileyo zinokuxutywa ngokukhawuleza namanzi ukufumana ukuhambelana okufunekayo. I-ether ye-cellulose inyibilika ngokukhawuleza kwaye ayidibanisi. I-Methylcellulose inokuxutywa kunye nomgubo owomileyo kwizinto zokwakha. Ineempawu zokusasazwa kwamanzi abandayo, kwaye inokwenza umxube ube-ethe-ethe ngakumbi kwaye kunye namasuntswana aqinileyo amisiweyo. Ukongeza, inokonyusa i-lubricity kunye neplastikhi, yandise ukuqhubekeka, kwaye yenza ukwakhiwa kwemveliso kube lula ngakumbi. Ukugcinwa kwamanzi okongeziweyo kunye neeyure zokusebenza ezinde zinceda ukuthintela ukuhamba ngokuthe nkqo kodaka kunye neethayile, ukwandisa ixesha lokupholisa, kunye nokuphucula ukusebenza kakuhle.
I-Hydroxypropylmethylcellulose inokuphucula amandla okubambisana kwe-ceramic tile adhesives, ukuphucula ukunyanzeliswa kwe-crack of mortar kunye ne-wood joints, kungekhona nje ukwandisa umxholo womoya kwi-mortar, kodwa nokunciphisa kakhulu amathuba okuqhekeka. Isenokuphucula inkangeleko yemveliso kwaye iphucule ukuchasana nokuncamathela kwethayile ye-ceramic.
