HPMC esetyenziswa kwiI-Wall Putty/Skim Coat

I-HPMC inokohlulwa ibe: ibakala lokwakha, ibakala lokutya kunye nebakala lezonyango ngokwendlela yokusetyenziswa. NgokueTshayina is ibakala lokwakha ubukhulu becala, kwiklasi yokwakha,Iputty eludongeni/Skim Coat umthamo weidyasi etyibilikayo umgubo mkhulu kakhulu. HPMC umgubo kunye nenani elikhulu lezinye izithako izinto engumgubo, ixutywe ngokupheleleyo blender, uze wongeze amanzi ukunyibilika, ngeli xesha HPMC unako ukunyibilika, kodwa hayi agglomerate, kuba ikona nganye encinane, umgubo kancinane HPMC, amanzi ngoko nangoko ukunyibilika.Skim Coatumgubo kunye neshishini lokuvelisa udaka sebenzisa olu hlobo lwendlela ngakumbi. IHydroxypropyl methyl cellulose (HPMC) isetyenziswa njengento etyebisayo kunye nearhente yokugcina amanzi kwiputty mortar.

Ukushisa kwejel ye-HPMC kuhambelana nomxholo we-methoxyl, i-methoxyl ephantsiphantsi, ubushushu bejeli buphezulu up. HPMC amanzi abandayo ngoko nangoko isisombululo uhlobo emva unyango umphezulu glyoxal, ifakwe emanzini abandayo ngokukhawuleza yachithwa, kodwa hayi ngokwenene inyibilike, viscosity phezulu, inyibilika. I-thermosoluble HPMC Uhlobo aluzange luphathwe nge-glyoxal. Ubungakanani be-glyoxal bukhulu, ukusabalalisa ngokukhawuleza, kodwa i-viscosity iyacotha, inani lincinci, ngokuchaseneyo. HPMC inokohlulwa ibe ngoko nangoko kunye nobushushu enyibilikayo, iimveliso ngoko nangoko, emanzini abandayo ngokukhawuleza sachithwa, wanyamalala emanzini, ngeli xesha ulwelo akukho viscosity, ngenxa yokuba HPMC nje yachithwa emanzini, akukho unyibiliko lokwenene. Malunga nemizuzu emi-2, i-viscosity yolwelo iyanda ngokuthe ngcembe, yenze i-colloid ebonakalayo ebonakalayo. Ubushushu iimveliso ezinyibilikayo, kumanzi abandayo agglomeration, inokuba kumanzi ashushu, ngokukhawuleza saa, zinyamalale emanzini ashushu, de iqondo lobushushu lehla kwiqondo elithile lobushushu, viscosity ngokucothayo avele, de ukubunjwa transparent viscous colloid. Uhlobo olunyibilikayo lobushushu lunokusetyenziswa kuphela ngaphakathiSkim Coat kunye nodaka, kwiglue elulwelo kunye nokwaleka, kunokuvela into ye-agglomeration, ayinakusetyenziswa. Imodeli yokunyibilika ngoko nangoko, umda wesicelo ubanzi, ngaphakathiSkim Coatumgubo kunye nodaka, kunye neglue elulwelo kunye nokwaleka, zonke zingasetyenziswa, musa ukuba yintoni taboo.

Indlela yokunyibilikisa yokuvelisa i-HPMC, yenziwe nge-toluene, isopropyl alcohol solvent, ukuba ukuhlamba akulunganga kakhulu, kuya kubakho incasa eseleyo. usetyenziso lweSkim Coat  powder: imfuno ingaphantsi, i-viscosity 100000, kubalulekile ukukhusela amanzi ukuba abe kufutshane. Ukusetyenziswa kodaka: iimfuno eziphezulu, iimfuno eziphezulu ze-viscosity, i-150000 ukuba ngcono. Ukusetyenziswa kweglue: imfuno yeemveliso ezikhawulezayo, i-viscosity ephezulu. I-HPMC ekusetyenzisweni kwangempela kwesixa, ngokusingqongileyo kwemozulu, ubushushu, umgangatho wekhalsiyam engwevu yendawo,Skim Coat ifomula kunye "neemfuno zabathengi bomgangatho" ezahlukeneyo, kwaye kukho umahluko. IHydroxypropyl methyl cellulose (HPMC) ye-viscosity –Skim Coatumgubo yi100000, ezinye zide zemfuneko kudaka, zifuna i-150 lamawaka amandla okusebenzisa. Ngaphezu koko, indima ephambili ye-HPMC kukugcina amanzi, kulandele ukujiya. KwiSkim Coat, ngokude nje ukugcinwa kwamanzi kulungile, i-viscosity iphantsi (7-80000), kwakhona kunokwenzeka, ngokuqinisekileyo, i-viscosity inkulu, ukugcinwa kwamanzi okuhambelanayo kungcono, xa i-viscosity ingaphezulu kwe-100.000, i-viscosity yokugcinwa kwamanzi ayininzi; Umxholo weHydroxypropyl uphezulu, ukugcinwa kwamanzi ngokuqhelekileyo kungcono. I-Viscosity, ukugcinwa kwamanzi, ngcono ngakumbi, kunye ne-viscosity, kumdaka we-samente isetyenziswe ngcono.

HPMC ngaphakathiSkim Coat, ukuqina, ukugcinwa kwamanzi kunye nokwakhiwa kwemisebenzi emithathu. Ukungathathi nxaxheba kuyo nayiphi na impendulo. Unobangela iqamza inokuba amanzi kakhulu, inokuba kwakhona ezantsi ayomileyo, phezu umaleko ukukhuhla, kwakhona lula iqamza. HPMC kwisiphumo ukutyeba yeSkim Coat: i-cellulose inokugqithwa ukunqunyanyiswa, ukwenzela ukuba isisombululo sihlale sifanayo phezulu nasezantsi indima yokuxhoma okuchasayo. Isiphumo sokugcinwa kwamanzi HPMC kwiSkim Coat: yenzaSkim Coat yome ngokucothayo, i-axiliary gray calcium reaction phantsi kwesenzo samanzi. HPMC ngaphakathiSkim Coat indima yokwakha: i-cellulose lubrication, inokwenzaSkim Coat inolwakhiwo oluhle. I-HPMC ayithathi nxaxheba kuyo nayiphi na intshukumo yeekhemikhali, kodwa idlala indima exhasayo kuphela.

Iputty eludongeni/Skim Coat umgubo kunye nomgangatho oyintloko we-ash calcium unobudlelwane obukhulu, kwaye i-HPMC ayinalo ubudlelwane obukhulu. Umxholo ophantsi we-calcium we-gray calcium kunye nomlinganiselo ongafanelekanga we-CaO kunye ne-Ca (OH) 2 kwi-gray calcium iya kubangela ukuhla kwepowder. Ukuba kukho ubudlelwane obuncinci kunye ne-HPMC, ke yi-HPMC yokugcinwa kwamanzi okungahambi kakuhle, kuya kubangela ukuba umgubo,Skim Coat kunye namanzi, eludongeni, yi-chemical reaction, ngenxa yokuveliswa kwezinto ezintsha, udonga lweSkim Coat phantsi eludongeni, umhlaba ube ngumgubo, uze usebenzise, ​​kungekhona umgca, kuba uye waqulunqa into entsha (i-calcium carbonate). Amacandelo aphambili e-gray calcium powder ngala: Ca (OH) 2, CaO kunye nomlinganiselo omncinci weCaCO3 umxube, iCaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+ I-H2O i-calcium engwevu emanzini kunye nomoya phantsi kwesenzo se-CO2, ukubunjwa kwe-calcium carbonate, kunye ne-HPMC yamanzi kuphela, i-gray encedisayo ye-calcium yokusabela ngcono, eyayo ayizange ithathe inxaxheba kuyo nayiphi na impendulo.
