Yintoni i-viscosity ye-hydroxypropyl methylcellulose hpmc?

I-putty powder yeendonga zangaphakathi ngokubanzi ine-viscosity ye-100,000. Umdaka we-samente uneemfuno eziphezulu zokulungiswa, kunye ne-viscosity ye-150,000 kulula ukuyisebenzisa. Ukongeza, eyona ndima ibalulekileyo ye-HPMC kukutshixa amanzi, kulandele ukujiya. Kwi-putty powder, ukuba ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (i-7-80,000), ingaba ne-viscosity ephezulu yendalo kunye nokugcinwa kwamanzi okungcono. Xa i-viscosity idlula i-100,000, i-viscosity inefuthe elincinci ekugcinweni kwamanzi.

Yintoni isiphumo esingundoqoI-HPMC kwiputty powder, kwaye ingaba i-organic chemistry iyenzeka?

I-HPMC idlala imisebenzi emithathu yokuqina, ukugcinwa kwamanzi kunye nokwakhiwa kwiputty powder.

Ukuqina: I-Methylcellulose inokugxininiswa kunye nezisombululo ezidadayo, ezinamanzi ukuze kugcinwe ukusebenza okufanayo kunye nokungaguquguqukiyo kunye nokuthintela ukuhamba okujingayo.

Ukugcinwa kwamanzi: Umgubo wodonga lwangaphakathi loma kancinci, kwaye i-calcium lime eyongeziweyo ibonakala ekusebenziseni amanzi.

Ukwakhiwa kobunjineli: I-Methyl cellulose inefuthe lokuthambisa, elinokwenza i-putty powder ibe nesakhiwo sobunjineli esihle kakhulu.

I-HPMC ayibandakanyekanga kuzo zonke iinguqu zeekhemikhali kodwa kuphela ekuncediseni. I-putty powder, eludongeni, utshintsho lweekhemikhali, kuba kukho ukuguqulwa kwezinto ezintsha zeekhemikhali, i-putty powder iphuma eludongeni, igaye i-powder, kwaye iphinda isebenzise ngenxa yokuba ikhemikhali entsha (i-calcium carbonate) yenziwe.

Amalungu aphambili e-calcium fly ash ngala: Ca(oh)2, Cao kunye nentwana encinci yeCaco3 compounds, iCaoh2oCa(oh)2-Ca(oh)2caco3h2o lime inokuguqulwa ibe yicalcium bicarbonate emanzini nakwirhasi, ngelixa i-mpc ise kuphela amanzi anyibilikayo Calcium fly ash yi reflection enamandla, nto leyo ngokwayo ayithabathi nxaxheba kuyo nayiphi na reflection.

Yintoni ekufuneka ihlawulwe kwisicelo sokwenene sobudlelwane phakathi kwe-viscosity kunye nobushushu be-HPMC?

I-viscosity ye-HPMC ihambelana ngokungafaniyo nobushushu, ngamanye amazwi, i-viscosity iyanda ngokuhla kweqondo lokushisa. I-viscosity yemveliso, i-viscosity yemveliso ithetha ukuba isisombululo sayo se-2% sikwiqondo lokushisa lama-20 degrees Celsius, kunye neziphumo zovavanyo.

Kwizicelo ezithile, ingqalelo kufuneka ihlawulwe kwiindawo ezinomahluko omkhulu wobushushu phakathi kwehlobo nobusika, kwaye kucetyiswa ngamandla ukuba kusetyenziswe i-viscosity ephantsi ebusika. Ngaphandle koko, i-viscosity iphantsi, i-viscosity ye-cellulose iya kwanda, kwaye i-scratches iya kuba nzima.

I-viscosity ephakathi: 75000-100000 ifanelekile kwiputty powder
Isizathu: ukugcinwa kakuhle kwamanzi

I-viscosity ephezulu: i-150000-200000 ifanelekile kwi-polystyrene particle insulation mortar kunye ne-inorganic insulation mortar.
Izizathu: i-viscosity ephezulu, ukususwa okunzima kwe-cement mortar, ukulahleka kwe-gloss, ukwakhiwa okuphuculweyo.
