Iinkalo zesicelo
1.Ulwakhiwo:
Njenge-arhente yokugcina amanzi kunye ne-retarder yodaka lwesamente, yenza ukuba udaka lumpompe.Isetyenziswe njenge-binder kwi-plaster, i-putty powder okanye ezinye izinto zokwakha ukuphucula ukusasazeka kunye nokwandisa ixesha elivulekileyo.Ipropati yokugcina amanzi ye-hydroxypropyl methylcellulose HPMC ikhusela i-slurry ekuqhekekeni ngenxa yokoma ngokukhawuleza emva kokusetyenziswa, kwaye iphakamisa amandla emva kokuqina.
1) I-Tile Adhesives
Izincamathelisi zethayile ezisemgangathweni zizalisekisa zonke iimfuno zamandla okubambelela kwi-C1 yokuncamathelisa ithayile.Ngokuzithandela banako ukuxhathisa ukutyibilika okuphuculweyo okanye ixesha elivulekileyo elongeziweyo .I-adhesives ye-tile esemgangathweni ingaba yimimiselo eqhelekileyo okanye ukusetha ngokukhawuleza.
Ukunamathiswa kweetayile zesamente kufuneka kube lula ukutshixa.Kufuneka banike ixesha elide lokubethelela, ukuchasana nokutyibilika okuphezulu kunye namandla okwaneleyo okubambelela.Ezi propati zinokuphenjelelwa yi-HPMC.I-adhesives yokubeka ibhloko isetyenziselwa ukwakha iindonga zeebhloko zekhonkrithi ene-aerated, izitena zesanti okanye izitena eziqhelekileyo.I-adhesives ye-tile iqinisekisa ubudlelwane obuhle phakathi kwe-substrate kunye neebhodi ze-insulating.I-HPMC iphucula ukusebenza kwezinto zokuncamathelisa iTile kwaye yandisa ukuncamathela kunye nokumelana ne-sag.
• Ukusebenza ngcono: ukuthambisa kunye neplastiki yodaka kuqinisekiswa, udaka lunokufakwa lula kwaye lukhawuleza.
•Ukugcinwa kakuhle kwamanzi: ixesha elide lokuvula liya kwenza ukuba iithayile zisebenze kakuhle.
• Ukubambelela okuphuculweyo kunye nokumelana nokutyibilika: ngakumbi kwiithayile ezinzima.
2) Udaka oluxubileyo olomileyo
Udaka oluxutyiweyo olomileyo luyimixube yee-mineral binders, aggregates kunye nabancedisi.Kuxhomekeke kwinkqubo, kukho umahluko phakathi kwesandla kunye nesicelo somatshini.Zisetyenziselwa ukugquma isiseko, ukugquma, ukulungiswa kunye neenjongo zokuhombisa.Udaka oluxubeneyo olomileyo olusekelwe kwisamente okanye i-samente / i-hydrated lime ingasetyenziselwa umsebenzi wangaphandle nangaphakathi.Unikezelo olusetyenziswa ngoomatshini luxutywa kumatshini wokutyabeka ngokuqhubekayo okanye ngokuyekisa ukusebenza.Oku kuvumela ukugubungela udonga olukhulu kunye neendawo zesilingi ngobuchule obusebenzayo.
• Ifomula yokuxuba eyomileyo elula ngenxa yokunyibilika kwamanzi abandayo: ukubunjwa kweqhuma kunokuphetshwa ngokulula, ilungele iithayile ezinzima.
• Ukugcinwa kakuhle kwamanzi: uthintelo lokulahleka kwamanzi kwii-substrates, umxholo wamanzi ofanelekileyo ugcinwa kumxube oqinisekisa ixesha elide lokudibanisa.
3) Ukuzilinganisa
Iikhompawundi zomgangatho ozilinganiselayo zisetyenziselwa ukugudisa nokulinganisa zonke iintlobo zesubstrates kwaye zinokusetyenziswa njengendawo yangaphantsi umz. iithayile neekhaphethi.Ukunqanda intlenga kunye nokugcina flowability, viscosity low HPMC amabakala asetyenziswa.
•Ukukhuselwa ekukhutshweni kwamanzi kunye nentlenga yezinto.
• Akukho mpembelelo kwi-slurry fluidity kunye ne-viscosity ephantsi
I-HPMC, ngelixa iimpawu zayo zokugcina amanzi ziphucula ukusebenza kokugqiba kumphezulu.
4) I-Crack Filler
·Ukusebenza ngcono: ubukhulu obufanelekileyo kunye neplastiki.
·Ukugcinwa kwamanzi kuqinisekisa ixesha elide lomsebenzi.
·Ukuxhathisa kweSag: ukukwazi ukuphuculwa kodaka.
5) I-Plaster esekelwe kwi-Gypsum
I-Gypsum sisixhobo sokwakha esisekwe kakuhle kwizicelo zangaphakathi.Inika ukusebenza kakuhle kwaye ixesha layo lokumisela linokulungiswa kwisicelo ngasinye njengoko kufuneka.Izinto zokwakha ze-Gypsum zivelisa umoya wokuphila okhululekileyo ngenxa yokulinganisela kokufuma okuhle.Ukongeza, i-gypsum ibonisa ukumelana nomlilo.Nangona kunjalo, ayinamanzi, ngoko ke ukusetyenziswa kwangaphakathi kuphela kunokwenzeka.Ukudibanisa i-gypsum kunye ne-hydrated lime zixhaphake kakhulu kwi-plaster formulations.
•Ukonyuka kwemfuno yamanzi: ixesha elivulekileyo elongeziweyo, indawo eyandisiweyo yespry kunye nokwakhiwa okunoqoqosho ngakumbi.
• Ukusasazeka lula kunye nokuphucula ukuxhathisa ukudodobala ngenxa yokuphucula ukungaguquguquki.
6) I-putty yodonga / i-Skimcoat
• Ukugcinwa kwamanzi: ukwandisa umthamo wamanzi eludaka.
Ukuchasana nokugrumba: xa usasaza i-corrugation yedyasi engqindilili inokuphetshwa.
•Ukonyuka kwesivuno sodaka: ngokuxhomekeke kubunzima bomxube owomileyo kunye nokwakheka okufanelekileyo, i-HPMC inokunyusa umthamo wodaka.
7) I-Insulation yangaphandle kunye neNkqubo yokuQeda ( EIFS )
Cementitious zokuncamathelisa ibhedi obhityileyo zisetyenziselwa ukubambelela iithayile ceramic, ukwakha iindonga zekhonkrithi aerated okanye izitena lekalika ilitye kunye nokufakela umphandle insulating iinkqubo zokugqiba (EIFS) .Babonelela ukusebenza lula nokukhanya, ukusebenza kakuhle eliphezulu kwaye isiqinisekiso ukuqina elide.
•Ukuphuculwa kokuncamathela.
•Ikhono elihle lokumanzisa kwibhodi ye-EPS kunye ne-substrate.
•Ukuncitshiswa kokungena komoya kunye nokungena kwamanzi.
