☑ 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 LK20M 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 ekukhishweni 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.
