Iipropati zayo ze-thixotropic zivumela i-putty ukuba ihlale kwindawo emva kwesicelo ngaphandle kokugubha.
Ugcino lwamanzi olomeleziweyo:
Ngokugcina amanzi, i-MHEC iqinisekisa ukuba i-putty ihlala isebenza ixesha elide, ukunciphisa umngcipheko wokumisa kwangaphambi kwexesha.
Eli xesha landisiweyo lokusebenza livumela uhlengahlengiso olungcono kunye nokugudiswa ngexesha lokufaka isicelo.
Ukuncamathela okuPhezulu:
I-MHEC iphucula iipropathi zokuncamathelisa ze-putty, iqinisekisa ukuba inamathela kakuhle kwii-substrates ezahlukeneyo ezifana nekhonkrithi, igypsum, kunye nezitena.
Ukubambelela okomeleziweyo kunciphisa amathuba okuqhekeka kunye nokuqhawulwa kwexesha.
Ukonyuka koKuhlala ixesha elide:
Ikhono lokwenza ifilimu ye-MHEC yenza umqobo wokukhusela ophucula ukuqina kwe-putty layer.
Lo mqobo ukhusela indawo engaphantsi kumswakama kunye nezinto ezisingqongileyo, ukwandisa ubomi besicelo se-putty.
Indima ye-MHEC kwiPlaster
I-Plaster isetyenziselwa ukudala iindawo ezigudileyo, ezihlala zihlala kwiindonga kunye neesilingi, rhoqo njengesiseko sokugqiba umsebenzi oqhubekayo.Iingenelo ze-MHEC kuqulunqo lwe-plaster zibalulekile:
Uphuculo lokuhambelana kunye nokuSebenza:
I-MHEC iguqula i-rheology ye-plaster, yenza kube lula ukuxuba nokusebenzisa.
Ibonelela ngokuhambelana, ukuthungwa kwekhrimu eyenza kube lula ukusetyenziswa ngaphandle kwamaqhuma.
Ugcino lwamanzi olomeleziweyo:
Ukunyangwa ngokufanelekileyo kwe-plaster kufuna ukugcinwa komswakama okwaneleyo.I-MHEC iqinisekisa ukuba udaka lugcina amanzi ixesha elide, luvumela ukuhanjiswa okupheleleyo kwamasuntswana esamente.
Le nkqubo yonyango elawulwayo ibangela ukuba umaleko wodaka owomeleleyo kwaye womelele ngakumbi.
Ukuncipha kweeNceba:
Ngokulawula izinga lokumisa, i-MHEC inciphisa umngcipheko wokuqhekeka kwe-shrinkage enokuthi yenzeke ukuba i-plaster yoma ngokukhawuleza.
Oku kukhokelela kwi-plaster surface ezinzileyo kunye nefanayo.
Ukuncamathela okungcono kunye noManyano:
I-MHEC iphucula iimpawu zokubambelela kwi-plaster, iqinisekisa ukuba idibanisa kakuhle kunye ne-substrates eyahlukeneyo.
Ukubambisana okuphuculweyo ngaphakathi kwe-matrix ye-plaster kubangela ukuqiniswa ngakumbi kunye nokugqitywa kwexesha elide.
IiNdlela zokuPhucula uMsebenzi
Ukuguqulwa kweViscosity:
I-MHEC yandisa i-viscosity yezisombululo zamanzi, ezibaluleke kakhulu ekugcineni uzinzo kunye ne-homogeneity ye-putty kunye ne-plaster.
Umphumo wokuqina we-MHEC uqinisekisa ukuba imixube ihlala izinzile ngexesha lokugcinwa kunye nesicelo, ukukhusela ukuhlukana kwamacandelo.
Ulawulo lweRheology:
Ubume be-thixotropic be-MHEC buthetha ukuba i-putty kunye ne-plaster ibonisa ukuziphatha okuchetywa kwe-shear-thinning, iyancipha i-viscous phantsi koxinzelelo lwe-shear (ngexesha lesicelo) kunye nokubuyisela i-viscosity xa uphumle.
Le propati ivumela usetyenziso olulula kunye nokuguqulwa kwezinto, kulandelwa ukuseta ngokukhawuleza ngaphandle kokugoba.
Ukwenziwa kwefilimu:
I-MHEC yenza ifilimu eguquguqukayo kwaye eqhubekayo phezu kokumisa, eyongeza kumandla omatshini kunye nokuchasana kwe-putty esetyenzisiweyo kunye ne-plaster.
Le filimu isebenza njengesithintelo esichasene nezinto ezisingqongileyo ezifana nokufuma kunye nokutshintsha kweqondo lokushisa, ukuphucula ixesha elide lokugqitywa.
