I-Hydroxypropyl Methyl Cellulose/Hypromellose/HPMC egcina amanzi yokwakha

incazelo emfushane:

I-MODCELLI-Hydroxypropyl Methyl Cellulose(HPMC), akuyona i-ionicama-ether e-cellulosekukhiqizwa kusuka ku-cellulose yemvelo enama-molecule amaningi (ukotini ohlanziwe) ngokusebenzisa uchungechunge lokusabela kwamakhemikhali.

Zinezici zokuncibilika kwamanzi,ukugcina amanziimpahla, uhlobo olungeyona i-ionic, inani le-PH elizinzile, umsebenzi wobuso, ukuguquguquka kokuxazulula i-gelling ekushiseni okuhlukile, ukuqina, ukwakha ifilimu ngesimenti, impahla yokugcoba, ukumelana nesikhunta njll.

Ngazo zonke lezi zici, zisetshenziswa kakhulu enqubweni yokuqina, ukugaya, ukuzinza kokumiswa, kanye nezimo zokugcina amanzi.

☑ Isitoreji kanye nokulethwa

Kufanele igcinwe futhi ilethwe ngaphansi kwezimo ezomile nezihlanzekile ngesimo sayo sokuqala sephakheji futhi kude nokushisa. Ngemva kokuba iphakheji selivuliwe ukuze likhiqizwe, kufanele livalwe kabusha ngokuqinile ukuze kugwenywe ukungena komswakama.

Iphakheji: 25kg/isikhwama, isikhwama sepulasitiki esihlanganisiwe sephepha esinezingqimba eziningi esinokuvulwa kwevalvu engezansi eyisikwele, nesikhwama sefilimu ye-polyethylene esingaphakathi.

☑Isikhathi sokuphelelwa yisikhathi

Isikhathi sewaranti siyiminyaka emibili. Sisebenzise kusenesikhathi ngangokunokwenzeka ngaphansi kokushisa okuphezulu kanye nomswakama, ukuze ungakhulisi amathuba okubamba ikhekhe.

☑Ukuphepha komkhiqizo

I-Hydroxypropyl methyl cellulose HPMC LK40M ayiyona eyezinto eziyingozi. Ulwazi olwengeziwe ngezici zokuphepha lunikezwe ku-Material Safety Data Sheet.

Imibuzo Evame Ukubuzwa

Kuyini i-Hydroxypropyl Methyl Cellulose?

I-Hydroxypropyl methylcellulose (HPMC) yi-cellulose ethers ebe namaqembu e-hydroxyl ku-cellulose chain athathelwe indawo yiqembu le-methoxy noma le-hydroxypropyl.It Kwenziwa ngokushintshashintsha okukhethekile kwe-cellulose kakotini emsulwa kakhulu ngaphansi kwezimo ze-alkaline. Eminyakeni yamuva nje, i-HPMC, njengengxube esebenzayo, idlala indima enkulusekugcinweni nasekuqineni kwamanzi embonini yokwakha futhi isetshenziswa kabanzi eizigqulo zokuxuba i-drymix, njenge-tile adhesive, ama-grout, i-plastering, i-wall putty, i-self leveling, i-insulation mortar njll.

Lihlobene Kanjani Izinga Lokushisa Lejeli Le-Hpmc?

Ngokuvamile, ngempuphu ye-putty, i-viscosity yeI-HPMCkwanele cishe ku-70,000 kuya ku-80,000. Ukugxila okuyinhloko ekusebenzeni kwayo kokugcina amanzi, kuyilapho umphumela wokujiya uncane kakhulu. Ku-mortar, izidingo ze-I-HPMCziphakeme, futhi i-viscosity idinga ukuba cishe yi-150,000, okungaqinisekisa ukuthi isebenza kangcono ku-cement mortar. Yiqiniso, ku-putty powder, inqobo nje uma ukusebenza kokugcinwa kwamanzi kwe-HPMC kukuhle, noma ngabe i-viscosity iphansi (70,000 kuya ku-80,000), kuyamukeleka. Kodwa-ke, ku-cement mortar, kungcono kakhulu ukukhetha i-HPMC ene-viscosity enkulu (engaphezu kwe-100,000), ngoba umphumela wayo wokugcinwa kwamanzi ubaluleke kakhulu kulesi simo.

Ingabe i-Putty Powder Iwa Odongeni Ihlobene ne-Hpmc?

Inkinga yokususwa kwempuphu ye-putty incike kakhulu kwikhwalithi ye-calcium hydroxide futhi ayihlobene kakhulu ne-HPMC. Uma okuqukethwe kwe-calcium ye-calcium hydroxide kuphansi noma isilinganiso se-CaO kanye ne-Ca(OH)2 singafaneleki, kungabangela ukuthi impuphu ye-putty iwe. Ngokuphathelene nomthelela we-HPMC, kubonakala kakhulu ekusebenzeni kwayo kokugcina amanzi. Uma ukusebenza kokugcina amanzi kwe-HPMC kukubi, kungase kube nomthelela othile ekususeni impuphu ye-putty.

Ungayikhetha Kanjani i-Hpmc Ngezinhloso Ezihlukile?

Izidingo zokusebenzisa i-putty powder ziphansi kakhulu. I-viscosity engu-100,000 yanele. Isihluthulelo ukuba nezakhiwo ezinhle zokugcina amanzi. Ngokuphathelene nodaka, izidingo ziphakeme kakhulu kanti i-viscosity ephezulu iyadingeka, kanti umkhiqizo ongu-150,000 unomthelela ongcono.
