☑ Ukugcinwa kunye nokuhanjiswa
Kufuneka igcinwe kwaye ihanjiswe phantsi kweemeko ezomileyo nezicocekileyo kwifom yephakheji yayo yokuqala kwaye kude nobushushu. Emva kokuba ipakethe ivulwe ukuveliswa, ukutywinwa kwakhona okuqinileyo kufuneka kuthathwe ukuphepha ukungena kokufuma.
Iphakheji: 25kg / ibhegi, iplastiki ehlanganisiweyo yamaphepha amaninzi kunye nokuvulwa kwevalve esezantsi, kunye nengxowa yefilimu ye-polyethylene yangaphakathi.
☑Beka ubomi kwishelufa
Ixesha lewaranti yiminyaka emibini. Yisebenzise kwangoko kunokwenzeka phantsi kobushushu obuphezulu kunye nomswakama, ukuze unganyusi amathuba okuba ne-caking.
☑Ukhuseleko lwemveliso
IHydroxypropyl methyl cellulose HPMC LK50M asiyonto eyingozi. Ulwazi oluthe vetshe ngemiba yokhuseleko lunikwe kwiPhepha leDatha loKhuseleko lweMathiriyeli.
FAQS
IHydroxypropyl methylcellulose (HPMC) zii-ether ze-cellulose ezibe namaqela e-hydroxyl kwikhonkco leselulosi endaweni ye-methoxy okanye iqela le-hydroxypropyl.It yenziwe nge-etherification ekhethekileyo ye-cotton cellulose ecocekileyo kakhulu phantsi kweemeko ze-alkaline. Kwiminyaka yakutshanje, i-HPMC, njenge-admixture esebenzayo, idlala indima enkulusekugcineni amanzi kunye nokutyeba kushishino lokwakha kwaye isetyenziswa ngokubanzi kwii-drymix mortars, njenge-adhesive tile, i-grouts, i-plastering, i-putty eludongeni, ukuzilinganisa, udaka lwe-insulation kunye njl.
Ngokuqhelekileyo, i-putty powder, i-viscosity yeHPMCyanele malunga nama-70,000 ukuya kuma-80,000. Ingqwalasela ephambili kukusebenza kwayo kokugcinwa kwamanzi, ngelixa isiphumo sokuqina sincinci. Ngodaka, iimfuno zeHPMCziphezulu, kwaye i-viscosity kufuneka ibe malunga ne-150,000, enokuqinisekisa ukuba isebenza ngcono kwi-samente yodaka. Ngokuqinisekileyo, kwi-putty powder, ngokude nje ukuba ukugcinwa kwamanzi kusebenze kwe-HPMC kulungile, nokuba i-viscosity iphantsi (i-70,000 ukuya kwi-80,000), iyamkeleka. Nangona kunjalo, kumdaka we-samente, kulungele ngakumbi ukukhetha i-HPMC ene-viscosity enkulu (ngaphezu kwe-100,000), kuba umphumo wayo wokugcina amanzi ubaluleke kakhulu kule meko.
Ingxaki yokukhutshwa kwe-putty powder ngokuyinhloko ixhomekeke kumgangatho we-calcium hydroxide kwaye ayinanto encinci ne-HPMC. Ukuba umxholo we-calcium we-calcium hydroxide uphantsi okanye umlinganiselo we-CaO kunye ne-Ca (OH) 2 awufanelekanga, unokubangela ukuba i-putty powder iwe. Ngokuphathelele impembelelo ye-HPMC, ibonakaliswe ikakhulu ekusebenzeni kwayo kokugcinwa kwamanzi. Ukuba ukusebenza kokugcinwa kwamanzi kwe-HPMC kubi, kunokuba nefuthe elithile kwi-depowdering of putty powder.
Iimfuno zokusetyenziswa kweputty powder ziphantsi. I-viscosity ye-100,000 yanele. Undoqo kukuba neempawu ezilungileyo zokugcina amanzi. Ngokumalunga nodaka, iimfuno ziphezulu kwaye i-viscosity ephezulu iyafuneka, kwaye imveliso ye-150,000 inesiphumo esingcono.
