Enqubweni yokukhiqiza ye-putty powder, enezela inani elifanele of IHydroxypropyl Methyl Cellulose (HPMC)ingathuthukisa ukusebenza kwayo, njengokuthuthukisa i-rheology ye-putty powder, ukwandisa isikhathi sokwakha, nokwandisa ukunamathela. I-HPMC iwugqinsi ovamile kanye nesiguquli, esisetshenziswa kabanzi ezintweni zokwakha, okokuhlanganisa, okunamathelisa kanye neminye imikhakha. Nge-putty powder, ukwengeza i-HPMC akukwazi nje ukuthuthukisa ukusebenza kokwakhiwa, kodwa futhi kuthuthukise umthamo wokugcwalisa kanye nokusebenza kokulwa nokuqhekeka kwe-putty.

 

Indima ye-hydroxypropyl methylcellulose
Ukuthuthukisa ukusebenza kwe-fluidity nokwakhiwa: I-HPMC inomphumela omuhle wokuqina, ongathuthukisa i-fluidity ye-putty powder, okwenza i-putty powder ibe yinto efanayo futhi mancane amathuba okugeleza lapho isetshenziswa futhi ilungiswa, futhi ithuthukise ukusebenza kahle kanye nekhwalithi yokwakha.

 

Ukuthuthukisa ukunamathela: Ukwengezwa kwe-HPMC kungathuthukisa ukunamathela phakathi kwe-putty powder kanye nezinto eziyisisekelo, ukugwema izinkinga ezifana ne-putty powder ewa nokuqhekeka.

 

Ukuthuthukisa ukugcinwa kwamanzi: I-HPMC ingakhuphula ukugcinwa kwamanzi kwe-putty powder, inciphise izinga lokuhwamuka kwamanzi, ngaleyo ndlela ivimbele i-putty ukuthi imile futhi iqhekeke, futhi isize i-putty ukugcina ukufana phakathi nenqubo yokomisa.

 

Ukumelana nokuqhekeka okuthuthukisiwe: Isakhiwo se-polymer se-HPMC singathuthukisa ukuguquguquka kwe-putty powder futhi sinciphise imifantu ebangelwa ukuqhekeka, ukushintsha kwezinga lokushisa noma ukuguqulwa kwesisekelo.

 

Inani le-Hydroxypropyl Methylcellulose Yengeziwe
Ngokuvamile, inani le-hydroxypropyl methylcellulose elengeziwe ngokuvamile liphakathi kuka-0.3% no-1.5% wesisindo esiphelele se-putty powder, kuye ngokuthi uhlobo lwe-putty powder olusetshenzisiwe, ukusebenza okudingekayo, kanye nezidingo zohlelo lokusebenza.

 

I-viscosity putty powder ephansi: Kwamanye ama-putty powders adinga uketshezi olungcono, inani eliphansi le-HPMC elingeziwe lingasetshenziswa, ngokuvamile lizungeze i-0.3% -0.5%. Ukugxila kwalolu hlobo lwe-putty powder ukuthuthukisa ukusebenza kokwakhiwa nokwandisa isikhathi esivulekile. I-HPMC eyeqile ingase ibangele i-putty powder ibe yi-viscous kakhulu futhi ithinte ukwakhiwa.

 

I-viscosity putty powder ephezulu: Uma umgomo uwukuthuthukisa ukunamathela nokumelana nokuqhekeka kwe-putty, noma izindonga ezinokwelashwa okuyisisekelo okunzima (njengezindawo ezinomswakama ophezulu), inani eliphakeme lokwengezwa kwe-HPMC lingasetshenziswa, ngokuvamile i-0.8% -1.5%. Ukugxila kwalawa ma-putty powders ukuthuthukisa ukunamathela, ukumelana nokuqhekeka nokugcinwa kwamanzi.

 

Isisekelo sokulungisa inani lokwengeza
Indawo esetshenziswayo: Uma indawo yokwakha inomswakama ophezulu noma izinga lokushisa eliphansi, inani le-HPMC elingeziwe livame ukukhuphuka ukuze kuthuthukiswe ukugcinwa kwamanzi nokusebenza okulwa nokuqhekeka kwe-putty powder.
Uhlobo lwe-putty: Izinhlobo ezahlukene ze-putty powder (ezifana ne-putty yangaphakathi yodonga, i-putty yangaphandle yangaphandle, i-fitty putty, i-coarse putty, njll.) inezidingo ezahlukene ze-HPMC. I-putty enhle idinga umphumela wokuqina, ngakho inani le-HPMC elisetshenzisiwe lizoba phezulu; kanti i-coarse putty, inani elengeziwe lingase libe lincane.
Isimo sesisekelo: Uma isisekelo simaholoholo noma sinokumunca amanzi okuqinile, kungase kudingeke ukuthi kwandiswe inani le-HPMC elingeziwe ukuze kuthuthukiswe ukunamathela phakathi kwe-putty nesisekelo.

 

Izinyathelo zokuphepha zokusebenzisa i-HPMC

Gwema ukwengeza ngokweqile: Nakuba i-HPMC ingathuthukisa ukusebenza kwe-putty powder, i-HPMC ngokweqile izokwenza i-putty powder ibe ne-viscous kakhulu futhi kube nzima ukuyakha, futhi ithinte ngisho nesivinini sokumisa kanye nobunzima bokugcina. Ngakho-ke, inani lokwengeza lidinga ukulawulwa ngokuya ngezidingo ezithile.

 

Inhlanganisela nezinye izithasiselo: I-HPMC ivame ukusetshenziswa ekuhlanganisweni nezinye izithasiselo ezifana ne-rubber powder, i-cellulose, njll. Uma isetshenziselwa ukuhlanganiswa namanye ama-thickeners noma ama-ejenti okugcina amanzi, kufanele kuqashelwe umphumela we-synergistic phakathi kwabo ukugwema izingxabano zokusebenza.

 

Ukuzinza kwezinto:I-HPMCiyinto encibilikayo emanzini. Ukwengeza ngokweqile kungase kubangele i-putty powder ukuthi imunce umswakama futhi yonane ngesikhathi sokugcinwa. Ngakho-ke, ngesikhathi sokukhiqiza nokugcinwa, inani le-HPMC elisetshenzisiwe kufanele licatshangelwe ukuze kuqinisekiswe ukuzinza kwe-putty powder ngaphansi kwezimo zokugcina ezivamile.

 

Ukwengeza i-HPMC ku-putty powder kungathuthukisa kakhulu ukusebenza kwayo, ikakhulukazi mayelana nokusebenza kokwakhiwa, ukugcinwa kwamanzi nokumelana nokuqhekeka. Ngokuvamile, inani elingeziwe le-HPMC liphakathi kuka-0.3% no-1.5%, elilungiswa ngokuvumelana nezidingo zezinhlobo ezahlukene ze-putty powder. Uma uyisebenzisa, kuyadingeka ukulinganisa umphumela wayo wokuqina nezidingo zokwakha ukuze ugweme imiphumela engadingekile ebangelwa ukusetshenziswa ngokweqile.
