Usetyenziso oluQhelekileyo lwe-HPMC:
I-Tile Adhesive
● Ukugcinwa kakuhle kwamanzi: ixesha elide lokuvula liya kwenza ukuba iithayile zisebenze kakuhle.
● Ukuphucula ukubambelela kunye nokumelana nokutyibilika: ngakumbi kwiithayile ezinzima.
● Ukusebenza okungcono: i-lubricity kunye neplastiki ye-plaster iqinisekisiwe, udaka lunokufakwa lula kwaye lukhawuleza.
Iplastikhi yesamente / Udaka lomxube owomileyo
● Ifomula yomxube owomileyo olula ngenxa yokunyibilika kwamanzi abandayo: ukubunjwa kweqhuma kunokuphetshwa ngokulula, ilungele iithayile ezinzima.
● Ukugcinwa kwamanzi okulungileyo: ukuthintela ukulahlekelwa kwamanzi kwii-substrates, umxholo wamanzi ofanelekileyo ugcinwa kumxube oqinisekisa ixesha elide lokuhlanganisa.
● Ukonyuka kwemfuno yamanzi: ixesha elivulekileyo elongeziweyo, indawo eyandisiweyo yespry kunye nokwakhiwa okunoqoqosho ngakumbi.
● Ukusasazeka lula kunye nokuphucula ukuxhathisa ukudodobala ngenxa yokuphucula ukuhambelana.
Iputty eludongeni
● Ukugcinwa kwamanzi: ukwandisa umthamo wamanzi eludaka.
● I-Anti-sagging: xa usasaza i-corrugation yedyasi engqindilili inokuphetshwa.
● Ukunyuswa kwesivuno sodaka: ngokuxhomekeke kubunzima bomxube owomileyo kunye nokwakheka okufanelekileyo, i-HPMC inokunyusa umthamo wodaka.
I-Insulation yangaphandle kunye neNkqubo yokuGqibela ( EIFS )
●Ukuphucula ukuncamathelisa.
● Ukukwazi ukumanzisa okulungileyo kwibhodi ye-EPS kunye ne-substrate.
● Ukuncitshiswa kokungena komoya kunye nokungena kwamanzi.
Ukuzilinganisa
● Ukukhuselwa ekukhutshweni kwamanzi kunye nentlenga yezinto.
● Akukho mpembelelo ku-slurry fluidity kunye ne-viscosity ephantsi
I-HPMC, ngelixa iimpawu zayo zokugcina amanzi ziphucula ukusebenza kokugqiba kumphezulu.
I-Crack Filler
● Ukusebenza ngcono: ubukhulu obufanelekileyo kunye neplastiki.
● Ukugcinwa kwamanzi kuqinisekisa ixesha elide lomsebenzi.
● Ukuxhathisa kwe-Sag: ukuphucuka kwekhono lokubopha udaka.
