☑ Ukugcinwa kunye nokuhanjiswa
Ifanele igcinwe kwaye ihanjiswe phantsi kweemeko ezomileyo nezicocekileyo kwimo yayo yokuqala yephakheji kwaye kude nobushushu. Emva kokuba iphakheji ivuliwe ukuze yenziwe, kufuneka ivalwe kwakhona ngokuqinileyo ukuze kuthintelwe ukungena komswakama.
Iphakheji: 25kg/ibhegi, ibhegi yeplastiki edityanisiweyo yephepha elinamaleko amaninzi enesithuba esisikwere sokuvula ivalvu esezantsi, kunye nebhegi yefilimu yepolyethylene enamaleko angaphakathi.
☑Beka ubomi kwishelufa
Ixesha lewaranti yiminyaka emibini. Yisebenzise kwangethuba kangangoko xa kushushu kakhulu kwaye kufuma, ukuze unganyusi amathuba okuba i-cake ibekwe.
☑Ukhuseleko lwemveliso
I-Hydroxypropyl methyl cellulose HPMC LK50M ayiyonto inobungozi. Ulwazi oluthe kratya malunga nemiba yokhuseleko lunikwe kwi-Material Safety Data Sheet.
Imibuzo ebuzwa rhoqo
I-Hydroxypropyl methylcellulose (HPMC) zii-cellulose ethers ebenamaqela e-hydroxyl kwi-cellulose chain ezithathelwe indawo yi-methoxy okanye i-hydroxypropyl group.It yenziwe nge-etherification ekhethekileyo ye-cotton cellulose ecocekileyo kakhulu phantsi kweemeko ze-alkaline. Kwiminyaka yakutshanje, i-HPMC, njengomxube osebenzayo, idlala indima enkulusekugcinweni nasekuqineni kwamanzi kwishishini lokwakha kwaye isetyenziswa kakhulu kwiiimortars zomxube owomileyo, ezifana ne-tile adhesive, ii-grouts, i-plastering, i-wall putty, i-self leveling, i-insulation mortar njl.
Ngokwesiqhelo, kwi-putty powder, i-viscosity yeI-HPMCyanele malunga nama-70,000 ukuya kuma-80,000. Eyona nto iphambili kukusebenza kwayo kokugcina amanzi, ngelixa isiphumo sokutyeba sincinci. Kwi-mortar, iimfuno zeI-HPMCziphezulu, kwaye i-viscosity kufuneka ibe malunga ne-150,000, nto leyo enokuqinisekisa ukuba isebenza ngcono kwi-samente mortar. Kakade ke, kwi-putty powder, logama nje ukusebenza kokugcinwa kwamanzi kwe-HPMC kulungile, nokuba i-viscosity iphantsi (70,000 ukuya kwi-80,000), iyamkeleka. Nangona kunjalo, kwi-samente mortar, kungcono ukukhetha i-HPMC ene-viscosity enkulu (ngaphezulu kwe-100,000), kuba isiphumo sayo sokugcina amanzi sibaluleke ngakumbi kule meko.
Ingxaki yokususwa komgubo we-putty ixhomekeke kakhulu kumgangatho we-calcium hydroxide kwaye ayinanto yakwenza ne-HPMC. Ukuba umxholo we-calcium we-calcium hydroxide uphantsi okanye umlinganiselo we-CaO kunye ne-Ca(OH)2 awufanelekanga, inokubangela ukuba umgubo we-putty uwe. Ngokuphathelele impembelelo ye-HPMC, ibonakala kakhulu ekusebenzeni kwayo kokugcina amanzi. Ukuba ukusebenza kokugcina amanzi kwe-HPMC kuphantsi, kunokuba nempembelelo ethile ekususeni umgubo we-putty.
Iimfuneko zokusebenzisa i-putty powder ziphantsi kakhulu. I-viscosity eyi-100,000 yanele. Isitshixo kukuba neempawu ezilungileyo zokugcina amanzi. Ngokuphathelele i-mortar, iimfuneko ziphezulu kwaye i-viscosity ephezulu iyafuneka, kwaye imveliso eyi-150,000 inesiphumo esingcono.
