Enqubweni yokukhiqiza i-putty powder, ukwengeza inani elifanelef I-Hydroxypropyl Methyl Cellulose (HPMC)ingathuthukisa ukusebenza kwayo, njengokuthuthukisa i-rheology yempuphu ye-putty, ukwandisa isikhathi sokwakha, nokwandisa ukunamathela. I-HPMC iyisithako esivamile sokujiya kanye nesiguquli, esisetshenziswa kabanzi ezintweni zokwakha, ezimbozweni, ezinamathelayo nakwezinye izinkambu. Kumpuphu ye-putty, ukwengeza i-HPMC akugcini nje ngokuthuthukisa ukusebenza kokwakha, kodwa futhi kuthuthukisa amandla okugcwalisa kanye nokusebenza kokulwa nokuqhekeka kwe-putty.

 

Indima ye-hydroxypropyl methylcellulose
Ukuthuthukisa ukugeleza nokusebenza kokwakhiwa: I-HPMC inomphumela omuhle wokujiya, ongathuthukisa ukugeleza kwempuphu ye-putty, okwenza impuphu ye-putty ifane kakhulu futhi ingabi namathuba amaningi okugeleza uma isetshenziswa futhi ilungiswa, futhi ithuthukise ukusebenza kahle kanye nekhwalithi yokwakha.

 

Ukuthuthukisa ukunamathela: Ukwengezwa kwe-HPMC kungathuthukisa ukunamathelana phakathi kwempuphu ye-putty nezinto eziyisisekelo, kugweme izinkinga ezifana nokuwa kwempuphu ye-putty nokuqhekeka.

 

Ukuthuthukisa ukugcinwa kwamanzi: I-HPMC ingandisa ukugcinwa kwamanzi kwempuphu ye-putty, yehlise izinga lokuhwamuka kwamanzi, ngaleyo ndlela ivimbele i-putty ukuthi yome futhi iqhekeke, futhi isize i-putty ukuthi ihlale ifana ngesikhathi senqubo yokomisa.

 

Ukumelana nokuqhekeka okuthuthukisiwe: Isakhiwo se-polymer se-HPMC singathuthukisa ukuguquguquka kwempuphu ye-putty futhi sinciphise ukuqhekeka okubangelwa ukuqhekeka, izinguquko zokushisa noma ukuguquka kwesisekelo.

 

Inani le-Hydroxypropyl Methylcellulose Elingeziwe
Ngokuvamile, inani le-hydroxypropyl methylcellulose elingeziwe livame ukuba phakathi kuka-0.3% no-1.5% wesisindo esiphelele sempuphu ye-putty, kuye ngohlobo lwempuphu ye-putty esetshenzisiwe, ukusebenza okudingekayo, kanye nezidingo zokusetshenziswa.

 

Impuphu ye-putty ene-viscosity ephansi: Kwamanye ama-putty powder adinga ukugeleza okungcono, kungasetshenziswa inani eliphansi lokwengeza le-HPMC, ngokuvamile cishe liyi-0.3%-0.5%. Ukugxila kwalolu hlobo lwempuphu ye-putty ukuthuthukisa ukusebenza kokwakhiwa nokwandisa isikhathi sokusebenza. I-HPMC eningi ingabangela ukuthi i-putty powder ibe yinkimbinkimbi kakhulu futhi ithinte ukwakhiwa.

 

Impuphu ye-putty ene-viscosity ephezulu: Uma umgomo uwukuthuthukisa ukunamathela kanye nokumelana nokuqhekeka kwe-putty, noma izindonga ezinokwelashwa okunzima kwesisekelo (njengezindawo ezinomswakama ophezulu), inani eliphezulu lokwengeza le-HPMC lingasetshenziswa, ngokuvamile liyi-0.8%-1.5%. Ukugxila kwalezi mpuphu ze-putty ukuthuthukisa ukunamathela, ukumelana nokuqhekeka kanye nokugcinwa kwamanzi.

 

Isisekelo sokulungisa inani lokwengeza
Indawo yokusebenzisa: Uma indawo yokwakha inomswakama ophezulu noma izinga lokushisa eliphansi, inani le-HPMC elingeziwe livame ukukhushulwa ukuze kuthuthukiswe ukugcinwa kwamanzi kanye nokusebenza kokulwa nokuqhekeka kwempuphu ye-putty.
Uhlobo lwe-putty: Izinhlobo ezahlukene ze-putty powder (njenge-interior wall putty, i-outer wall putty, i-fine putty, i-coarse putty, njll.) zinezidingo ezahlukene ze-HPMC. I-fine putty idinga umphumela wokujiya kakhulu, ngakho-ke inani le-HPMC elisetshenziswayo lizoba phezulu; kuyilapho ku-coarse putty, inani elingeziwe lingaba lincane kakhulu.
Isimo sesisekelo: Uma isisekelo siqinile noma sinokumuncwa kwamanzi okunamandla, kungadingeka ukwandisa inani le-HPMC elingeziwe ukuze kuthuthukiswe ukunamathelana phakathi kwe-putty nesisekelo.

 

Izinyathelo Zokuqapha Zokusebenzisa i-HPMC

Gwema ukwengeza ngokweqile: Nakuba i-HPMC ingathuthukisa ukusebenza kwempuphu ye-putty, i-HPMC eyengeziwe izokwenza impuphu ye-putty ibe lukhuni kakhulu futhi kube nzima ukuyakha, futhi ithinte ngisho nesivinini sokomisa kanye nokuqina kokugcina. Ngakho-ke, inani lokwengeza lidinga ukulawulwa ngokwezidingo ezithile.

 

Inhlanganisela nezinye izithasiselo: I-HPMC ivame ukusetshenziswa kanye nezinye izithasiselo ezifana nempuphu yerabha, i-cellulose, njll. Uma isetshenziswa kanye nezinye izithasiselo noma izinto zokugcina amanzi, kufanele kuqashelwe umphumela wokubambisana phakathi kwazo ukuze kugwenywe ukungqubuzana kokusebenza.

 

Ukuqina kwezinto ezibonakalayo:I-HPMCkuyinto encibilika emanzini. Ukwengeza ngokweqile kungabangela ukuthi i-putty powder imunce umswakama futhi yonakale ngesikhathi sokugcina. Ngakho-ke, ngesikhathi sokukhiqiza nokugcina, inani le-HPMC elisetshenzisiwe kufanele licatshangelwe ukuqinisekisa ukuzinza kwe-putty powder ngaphansi kwezimo ezijwayelekile zokugcina.

 

Ukwengeza i-HPMC ku-putty powder kungathuthukisa kakhulu ukusebenza kwayo, ikakhulukazi maqondana nokusebenza kokwakhiwa, ukugcinwa kwamanzi kanye nokumelana nokuqhekeka. Ngokuvamile, inani lokwengeza le-HPMC liphakathi kuka-0.3% no-1.5%, elilungiswa ngokwezidingo zezinhlobo ezahlukene ze-putty powder. Uma uyisebenzisa, kubalulekile ukulinganisela umphumela wayo wokujiya nezidingo zokwakha ukuze ugweme imiphumela engadingekile ebangelwa ukusetshenziswa ngokweqile.
