Ha ho tluoa lits'ebetsong tsa seretse, ho fihlella ts'ebetso e nepahetseng ho bohlokoa bakeng sa merero e atlehileng ea kaho.Motsoako o mong oa bohlokoa o ka ntlafatsang haholo ts'ebetso ke MHEC (Methyl Hydroxyethyl Cellulose).Sengoliloeng sena, re tla shebisisa likarolo tse sebetsang tsa ho sebelisa MHEC ho tseba lits'ebetso tsa seretse le ho notlolla bokhoni ba eona bo felletseng.
Ho utloisisa MHEC:
MHEC ke setlolo se entsoeng ka selulose se sebetsang e le moemeli oa ho boloka metsi ka har'a seretse.Litšobotsi tsa eona tse ikhethang li e thusa ho thibela ho tsoa mouoane pele ho nako le ho monya mongobo seretseng se metsi.Ka ho boloka metsi, MHEC e lelefatsa ts'ebetso ea hydration ea samente, e eketsa nako e sebetsang ea seretse.
Melemo ea MHEC ho Likopo tsa Mortar:
a.Nako e Atolositsoeng ea Mosebetsi: MHEC e lumella nako e telele ea ho sebetsa, e nolofalletsang ho sebelisoa ha seretse se mosesaane, samente e boreleli, le ho felisa tlhokahalo ea ho kenya metsi pele ho li-substrates tse monyang.
b.Plasticity e Ntlafetseng: Ho eketsoa ha MHEC ho seretse ho ntlafatsa polasetiki ea eona, ho etsa hore ho be bonolo ho kopanya, ho jala le ho bōptjoa.Sena se ntlafatsa ts'ebetso e akaretsang le boiphihlelo ba ts'ebeliso.
c.Nako ea ho Beha e Laolehileng: MHEC e sebetsa e le sehlaseli, e lokisa nako ea ho beha seretse se secha.Taolo ena e lumella ho feto-fetoha ha maemo le ho feto-fetoha ha maemo nakong ea kaho, ho netefatsa liphetho tse nepahetseng.
Mekhoa e sebetsang ea ho sebelisa:
a.Tekanyo e Nepahetseng: Ho bohlokoa ho fumana litekanyetso tse nepahetseng tsa MHEC ho ipapisitse le ts'ebetso e lakatsehang le litlhoko tse ikhethileng tsa projeke.Latela litataiso tsa moetsi 'me u etse liteko tse nyane ho lokisa litekanyetso.
b.Mokhoa oa ho Kopanya: Eketsa MHEC ho motsoako o omileng oa seretse butle-butle ha u ntse u kopanya, ho etsa bonnete ba ho hasana hantle.Ho kgothaletswa hore o sebelise thepa ea boleng bo phahameng ba ho kopanya ho finyella motsoako oa homogeneous.
c.Keketso ea Metsi: Fetola boemo ba metsi ho latela likhothaletso tsa moetsi le botsitso bo lakatsehang.Lintho tsa MHEC tse bolokang metsi li thusa ho boloka mongobo oa seretse, ho fokotsa kotsi ea ho omella pele ho nako.
d.Mekhoa ea Kopo: Sebelisa monyetla oa nako e telele ea mosebetsi e fanoeng ke MHEC ho sebelisa seretse ka hloko.Rereletsa 'me u bōpe seretse ka moo ho hlokahalang, ho netefatsa hore ho na le tšireletso le ho khomarela hantle.
MHEC ho Merero ea Bophelo ba Sebele:
Totobatsa merero e atlehileng moo MHEC e sebelisitsoeng ho fihlela ts'ebetso e nepahetseng, ho bonts'a ts'ebetso e ntlafetseng, ho fokotsa mosebetsi o mocha, le ho ntlafatsa boleng ba kaho ka kakaretso.Buisanang ka mathata a tobaneng le ona le kamoo MHEC e thusitseng ho a hlola.
Ho tseba ho sebelisa seretse ho hloka kutloisiso e phethahetseng ea metsoako e sebelisoang.Ka ho kenyelletsa MHEC ka har'a metsoako ea seretse, likonteraka li ka finyella ts'ebetso e nepahetseng, polasetiki e ntlafetseng, le taolo e ntlafetseng ea ho beha nako.Ha litlhoko tsa kaho li ntse li phahama, ho sebelisa matla a MHEC hoa hlokahala bakeng sa liphello tse atlehileng tsa morero.Amohela thepa ea MHEC e bolokang metsi, 'me u notlolle bokhoni ba eona ba ho isa lits'ebetso tsa hau tsa seretse boemong bo latelang ba bokhabane.
