☑ Isitoreji nokulethwa
Kufanele igcinwe futhi ilethwe ngaphansi kwezimo ezomile nezihlanzekile ngendlela yayo yephakeji yasekuqaleni futhi kude nokushisa. Ngemva kokuvulwa kwephakheji ukuze kukhiqizwe, ukuvala kabusha okuqinile kufanele kuthathwe ukugwema ukungena komswakama.
Iphakheji: 25kg/isikhwama, isikhwama sepulasitiki esiyinhlanganisela yephepha elinezingqimba eziningi esinokuvulwa kwevalvu engezansi eyisikwele, nesikhwama sefilimu esenziwe nge-polyethylene sangaphakathi.
☑Impilo yeshelufu
Isikhathi sewaranti iminyaka emibili. Yisebenzise ngokushesha ngangokunokwenzeka ngaphansi kokushisa okuphezulu nomswakama, ukuze ungakhulisi amathuba okwenza i-caking.
☑Ukuphepha komkhiqizo
I-Hydroxypropyl methyl cellulose HPMC LK50M ayiyona ingxenye eyingozi. Ulwazi olwengeziwe mayelana nezici zokuphepha lunikezwe ku-Material Safety Data Sheet.
FAQS
I-Hydroxypropyl methylcellulose (HPMC) ama-cellulose ether abe namaqembu e-hydroxyl ochungechungeni lwe-cellulose esikhundleni seqembu le-methoxy noma le-hydroxypropyl.It yenziwa nge-etherification ekhethekile ye-cotton cellulose ehlanzekile kakhulu ngaphansi kwezimo ze-alkali. Eminyakeni yakamuva, i-HPMC, njengenhlanganisela esebenzayo, idlala indima enkulusekugcinweni kwamanzi kanye nokuqina embonini yezokwakha futhi isetshenziswa kabanzi kui-drymix mortars, njenge-adhesive tile, grouts, plastering, wall putty, self leveling, insulation mortar nokunye.
Ngokuvamile, i-putty powder, i-viscosity yeI-HPMCkwanele cishe ku-70,000 kuya ku-80,000. Okugxilwe kakhulu ekusebenzeni kwayo kokugcinwa kwamanzi, kuyilapho umphumela wokujiya umncane uma kuqhathaniswa. Ngodaka, izimfuneko zeI-HPMCziphakeme, futhi i-viscosity idinga ukuba ibe ngu-150,000, engaqinisekisa ukuthi isebenza kangcono odakeni lukasimende. Yiqiniso, ku-putty powder, inqobo nje uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kuhle, noma ngabe i-viscosity iphansi (70,000 kuya ku-80,000), iyamukeleka. Kodwa-ke, odakeni lukasimende, kungcono kakhulu ukukhetha i-HPMC ene-viscosity enkulu (ngaphezu kuka-100,000), ngoba umphumela wayo wokugcina amanzi ubaluleke kakhulu kulesi simo.
Inkinga yokukhishwa kwe-putty powder ngokuyinhloko incike kwikhwalithi ye-calcium hydroxide futhi ayihlangene kancane ne-HPMC. Uma okuqukethwe kwe-calcium ye-calcium hydroxide iphansi noma isilinganiso se-CaO ne-Ca(OH)2 singalungile, kungase kubangele ukuba i-putty powder iwe. Mayelana nomthelela we-HPMC, ibonakala kakhulu ekusebenzeni kwayo kokugcinwa kwamanzi. Uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kungalungile, kungase futhi kube nomthelela othile ekuqothulweni kwe-putty powder.
Izidingo zokusetshenziswa kwe-putty powder ziphansi kakhulu. I-viscosity ye-100,000 yanele. Okubalulekile ukuthi ube nezindawo ezinhle zokugcina amanzi. Ngokuphathelene nodaka, izidingo ziphakeme kakhulu futhi i-viscosity ephakeme iyadingeka, futhi umkhiqizo we-150,000 unomphumela ongcono.
