Kwinkqubo yokuvelisa i-putty powder, ukongeza inani elifanelekileyo of IHydroxypropyl Methyl Cellulose (HPMC)inokuphucula ukusebenza kwayo, njengokuphucula i-rheology ye-putty powder, ukwandisa ixesha lokwakha, kunye nokwandisa ukunamathela. I-HPMC sisityebi esiqhelekileyo kunye nesilungisi, esisetyenziswa ngokubanzi kwizinto zokwakha, iingubo, izinto zokuncamathelisa kunye nezinye iindawo. Kwi-putty powder, ukongeza i-HPMC ayikwazi nje ukuphucula ukusebenza kokwakhiwa, kodwa iphinde ikhulise umthamo wokuzalisa kunye nokusebenza kwe-anti-cracking ye-putty.

 

Indima ye-hydroxypropyl methylcellulose
Ukuphucula i-fluidity kunye nokusebenza kokwakhiwa: I-HPMC inefuthe elihle lokuqina, elinokuphucula i-fluidity ye-putty powder, okwenza i-putty powder ibe yinto efanayo kwaye ayinakwenzeka ukuhamba xa isetyenziswe kwaye ilungiswa, kunye nokuphucula ukusebenza kunye nomgangatho wokwakha.

 

Ukuphucula ukubambelela: Ukongezwa kwe-HPMC kunokuphucula ukudibanisa phakathi kwe-putty powder kunye nesiseko sezinto eziphathekayo, ukuphepha iingxaki ezifana ne-putty powder ewa kunye nokuqhekeka.

 

Ukuphucula ukugcinwa kwamanzi: I-HPMC inokunyusa ukugcinwa kwamanzi kwi-putty powder, iyancipha izinga lokunyuka kwamanzi, ngaloo ndlela ikhusela i-putty ekumiseni nasekuqhekekeni, kwaye inceda i-putty ukugcina ukufana ngexesha lokumisa.

 

Ukuchasana nokuqhekeka okuphuculweyo: Isakhiwo se-polymer ye-HPMC inokuphucula ukuguquguquka kwe-putty powder kunye nokunciphisa ukuqhekeka okubangelwa ukuqhekeka, utshintsho lweqondo lokushisa okanye ukuguqulwa kwesiseko.

 

Isixa seHydroxypropyl Methylcellulose eyongeziweyo
Ngokuqhelekileyo, inani le-hydroxypropyl methylcellulose eyongeziweyo lihlala liphakathi kwe-0.3% kunye ne-1.5% yesisindo esipheleleyo se-putty powder, kuxhomekeke kuhlobo lwe-putty powder esetyenzisiweyo, ukusebenza okufunekayo, kunye neemfuno zesicelo.

 

I-powder ephantsi ye-viscosity putty: Kwezinye i-putty powders ezifuna i-fluidity engcono, i-HPMC encinci yokongeza ingasetyenziswa, ngokuqhelekileyo malunga ne-0.3% -0.5%. Ingqwalasela yolu hlobo lwe-putty powder kukuphucula ukusebenza kokwakhiwa kunye nokwandisa ixesha elivulekileyo. Ukugqithisa kwe-HPMC kunokubangela ukuba i-putty powder ibe yi-viscous kakhulu kwaye ichaphazele ukwakhiwa.

 

I-viscosity putty powder ephezulu: Ukuba injongo kukuphucula ukunamathela kunye nokuxhatshazwa kwe-crack ye-putty, okanye kwiindonga ezinobunzima bonyango olusisiseko (njengemimandla enomswakama ophezulu), i-HPMC ephezulu yokongeza ingasetyenziselwa, ngokuqhelekileyo i-0.8% -1.5%. Ingqwalasela yale mipuphu ye-putty kukuphucula ukubambelela, ukuxhathisa ukuqhekeka kunye nokugcinwa kwamanzi.

 

Isiseko sokulungelelanisa isixa sokongeza
Indawo yokusetyenziswa: Ukuba indawo yokwakha inomswakama ophezulu okanye ukushisa okuphantsi, inani le-HPMC elongezelelweyo lidla ngokunyuka ukuze kuphuculwe ukugcinwa kwamanzi kunye nokusebenza okuchasayo kwe-putty powder.
Uhlobo lweputty: Iindidi ezahlukeneyo zeputty (ezifana ne-putty yangaphakathi yodonga, i-putty yangaphandle yodonga, i-fitty putty, i-coarse putty, njl. njl.) zineemfuno ezahlukeneyo ze-HPMC. Iputty entle ifuna isiphumo sokujiya ngakumbi, ngoko ke inani le-HPMC elisetyenzisiweyo liya kuba phezulu; ngelixa i-coarse putty, imali eyongeziweyo inokuba ncinane.
Imeko yesiseko: Ukuba isiseko sirhabaxa okanye sinokufunxa okunamandla kwamanzi, kunokuba yimfuneko ukwandisa inani le-HPMC elongezelelweyo ukunyusa ukunamathela phakathi kwe-putty kunye nesiseko.

 

Imiqathango yokusebenzisa i-HPMC

Gwema ukongezwa okugqithisileyo: Nangona i-HPMC inokuphucula ukusebenza kwe-putty powder, i-HPMC egqithisileyo iya kwenza i-putty powder ibe yi-viscous kakhulu kwaye inzima ukuyakha, kwaye ichaphazele isantya sokumisa kunye nobunzima bokugqibela. Ngoko ke, isixa esongezelelweyo kufuneka silawulwe ngokweemfuno ezithile.

 

Ukudibanisa kunye nezinye izongezo: I-HPMC idla ngokusetyenziswa ngokudibeneyo kunye nezinye izongezo ezifana ne-rubber powder, i-cellulose, njl. Ukuba isetyenziswe ngokudibanisa nezinye ii-thickeners okanye ii-agents zokugcina amanzi, ingqalelo kufuneka ihlawulwe kwi-synergistic effect phakathi kwabo ukuphepha ukungqubana komsebenzi.

 

Uzinzo lwezinto:HPMCyinto enyibilikayo emanzini. Ukongezwa okugqithisileyo kunokubangela ukuba i-putty powder ifunxe umswakama kwaye yonakalise ngexesha lokugcinwa. Ngoko ke, ngexesha lokuvelisa kunye nokugcinwa, inani le-HPMC elisetyenzisiweyo kufuneka liqwalaselwe ukuqinisekisa ukuzinza kwe-putty powder phantsi kweemeko eziqhelekileyo zokugcina.

 

Ukongeza i-HPMC kwi-putty powder inokuphucula kakhulu ukusebenza kwayo, ngokukodwa ngokubhekiselele ekusebenzeni kokwakhiwa, ukugcinwa kwamanzi kunye nokuchasana nokuqhekeka. Ngokuqhelekileyo, inani elongezelelweyo le-HPMC liphakathi kwe-0.3% kunye ne-1.5%, ehlengahlengiswa ngokweemfuno zeentlobo ezahlukeneyo ze-putty powder. Xa uyisebenzisa, kuyimfuneko ukulungelelanisa umphumo wayo wokuqina kunye neemfuno zokwakha ukuze ugweme iziphumo ezingeyomfuneko ezibangelwa ukusetyenziswa ngokugqithiseleyo.
