I-HPMC isetshenziswe kuWall Putty/I-Skim Coat

I-HPMC ingahlukaniswa: Ibanga lokwakha, ibanga lokudla kanye nebanga lezokwelapha ngokusho kokusetshenziswa. OkwamanjeChina is ibanga lokwakha kakhulu, ekilasini lokwakha,Wall putty/I-Skim Coat umthamo weijazi le-skim impushana inkulu kakhulu. I-HPMC powder kanye nenani elikhulu lezinye izithako zezinto eziyimpuphu, ezixubene ngokugcwele ne-blender, bese ufaka amanzi ukuze uncibilike, ngalesi sikhathi i-HPMC ingancibilika, kodwa hhayi i-agglomerate, ngoba ikhona ngalinye elincane, i-HPMC powder encane, amanzi azoncibilika ngokushesha.I-Skim CoatIbhizinisi lokukhiqiza impuphu nodaka lisebenzisa lolu hlobo lwendlela ngaphezulu. I-Hydroxypropyl methyl cellulose (HPMC) isetshenziswa njenge-thickener kanye ne-ejenti egcina amanzi ku-putty mortar.

Izinga lokushisa lejeli le-HPMC lihlobene nokuqukethwe kwe-methoxyl, okuyehlisa okuqukethwe kwe-methoxylphansi, izinga lokushisa lejeli liphakeme up. HPMC amanzi abandayo osheshayo uhlobo isixazululo emva ukwelashwa glyoxal surface, ifakwe emanzini abandayo zihlakazeke ngokushesha, kodwa hhayi ngempela ziyoncibilika, viscosity up, is ziyoncibilika. I-thermosoluble I-HPMC uhlobo aluzange luphathwe nge-glyoxal. Inani le-glyoxal likhulu, ukuhlakazeka kuyashesha, kodwa i-viscosity ihamba kancane, inani lincane, ngokuphambene nalokho. I-HPMC ingahlukaniswa ibe esheshayo futhi encibilikayo ekushiseni, imikhiqizo esheshayo, emanzini abandayo ihlakazeke ngokushesha, yanyamalala emanzini, ngalesi sikhathi uketshezi alunayo i-viscosity, ngoba i-HPMC isanda kuhlakazeka emanzini, akukho ukuchithwa kwangempela. Cishe imizuzu emi-2, i-viscosity yoketshezi iyanda kancane kancane, yakha i-viscous colloid esobala. Ukushisa imikhiqizo encibilikayo, emanzini abandayo agglomeration, ingaba emanzini ashisayo, ahlakazeke ngokushesha, anyamalale emanzini ashisayo, kuze kube yilapho izinga lokushisa lehla liye ezingeni lokushisa elithile, i-viscosity ibonakala kancane, kuze kube yilapho kwakheka i-viscous colloid ebonakalayo. Uhlobo oluncibilikayo lokushisa lungasetshenziswa kuphela kuloI-Skim Coat kanye nodaka, ku-glue ewuketshezi kanye ne-coating, kungavela into ye-agglomeration, ayikwazi ukusetshenziswa. Imodeli yokuncibilika okusheshayo, ububanzi bohlelo lokusebenza bubanzi abambalwa, ngaphakathiI-Skim Coati-powder nodaka, futhi ku-glue ewuketshezi kanye ne-coating, konke kungasetshenziswa, akunayo i-taboo.

Indlela ye-solvent yokukhiqiza ye-HPMC, yenziwe nge-toluene, i-solvent ye-isopropyl alcohol, uma ukugeza kungalungile kakhulu, kuzoba khona ukunambitheka okusele. ukusetshenziswa kweI-Skim Coat  powder: imfuneko iphansi, viscosity 100000, kubalulekile ukuvikela amanzi ukuze abe seduze. Ukufakwa kodaka: izidingo eziphakeme, izidingo ze-viscosity ephezulu, i-150000 ukuba ngcono. Glue isicelo: isidingo imikhiqizo esheshayo, viscosity high. I-HPMC ekusetshenzisweni kwangempela kwenani, ngesimo sezulu, izinga lokushisa, ikhwalithi yendawo ye-calcium empunga,I-Skim Coat ifomula kanye "nezidingo zekhasimende zekhwalithi" zokuhlukile, futhi kukhona umehluko. I-Hydroxypropyl methyl cellulose (HPMC) ye-viscosity -I-Skim Coatimpushana100000, abanye abade bemfuneko odakeni, bafuna amandla ayizinkulungwane eziyi-150 okuwasebenzisa. Ngaphezu kwalokho, indima enkulu ye-HPMC ukugcina amanzi, okulandelwa ukujiya. KuI-Skim Coat, inqobo nje uma ukugcinwa kwamanzi kuhle, i-viscosity iphansi (7-80000), kungenzeka futhi, yebo, i-viscosity inkulu, ukugcinwa kwamanzi okuhlobene kungcono, lapho i-viscosity ingaphezu kuka-100000, i-viscosity yokugcinwa kwamanzi ayiningi; Okuqukethwe kwe-Hydroxypropyl kuphezulu, ukugcinwa kwamanzi ngokuvamile kungcono. I-viscosity, ukugcinwa kwamanzi, okungcono kakhulu, kanye ne-viscosity, odakeni lukasimende lusetshenziswa kangcono.

HPMC phakathiI-Skim Coat, ukujiya, ukugcinwa kwamanzi kanye nokwakhiwa kwemisebenzi emithathu. Ukungahlanganyeli kunoma yikuphi ukusabela. Isizathu bubble kungase kube amanzi amaningi kakhulu, kungase futhi kube phansi angomile, phezulu ungqimba ukukhuhla, futhi lula bubble. I-HPMC kumphumela wokujiya weI-Skim Coat: i-cellulose ingaqiniswa ukuze imiswe, ukuze ikhambi lihlale lifana phezulu naphansi indima ye-anti-flow hanging. Umphumela wokugcinwa kwamanzi we-HPMC kuI-Skim Coat: yenzaI-Skim Coat yome kancane, ukusabela okumpunga kwe-calcium ngaphansi kwesenzo samanzi. HPMC phakathiI-Skim Coat indima yokwakha: lubrication cellulose, kungenzaI-Skim Coat inokwakhiwa okuhle. I-HPMC ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusekela kuphela.

Wall putty/I-Skim Coat i-powder kanye nekhwalithi eyinhloko ye-ash calcium inobudlelwane obukhulu, futhi i-HPMC ayinabo ubuhlobo obuhle. I-calcium ephansi ye-calcium empunga kanye nengxenye engafanele ye-CaO ne-Ca(OH)2 ku-calcium empunga kuzobangela ukuwa kwempushana. Uma kukhona ubuhlobo obuncane ne-HPMC, khona-ke i-HPMC ukugcinwa kwamanzi okungalungile, kuzophinde kubangele impushana,I-Skim Coat futhi amanzi, odongeni, ukusabela kwamakhemikhali, ngenxa yokukhiqizwa kwezinto ezintsha, udonga lweI-Skim Coat phansi odongeni, kugaywe kube yimpushana, bese usebenzisa, hhayi umugqa, ngoba kwakheka into entsha (i-calcium carbonate). Izingxenye eziyinhloko zempushana ye-calcium empunga yilezi: I-Ca(OH)2, i-CaO kanye nenani elincane lengxube ye-CaCO3, i-CaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+H2O grey calcium emanzini nasemoyeni ngaphansi kwesenzo se-CO2, ukwakheka kwe-calcium carbonate, kanye ne-HPMC kuphela amanzi, i-axiliary gray calcium yokusabela kangcono, eyakhe ayizange ibambe iqhaza kunoma yikuphi ukusabela.
