Ho ntlafatsa Ts'ebetso ka MHEC bakeng sa Powder ea Putty le Polastering Powder

Methyl Hydroxyethyl Cellulose (MHEC) ke cellulose ether e atisang ho sebelisoa e le motenya, moemeli oa ho boloka metsi, le mofetoleli oa rheology linthong tsa kaho tse kang putty powder le plastering powder. Ho ntlafatsa ts'ebetso le MHEC ho kenyelletsa lintlha tse 'maloa ho fihlela thepa e lakatsehang joalo ka ho sebetsa, ho khomarela, ho hanyetsa, le litšobotsi tsa ho folisa. Mona ke mekhoa e meng ea ho ntlafatsa ts'ebetso ka MHEC ka phofo ea putty le phofo ea plastering:

1. Khetho ea Kereiti ea MHEC:
   • Khetha kereiti e nepahetseng ea MHEC ho latela litlhoko tse ikhethileng tsa kopo, ho kenyelletsa le viscosity e lakatsehang, ho boloka metsi, le ho lumellana le li-additives tse ling.
   • Nahana ka lintlha tse kang boima ba limolek'hule, tekanyo ea ho fetola, le mokhoa oa ho fetola ha u khetha sehlopha sa MHEC.
2. Ntlafatso ea litekanyetso:
   • Fumana litekanyetso tse nepahetseng tsa MHEC ho ipapisitse le lintlha tse joalo ka botsitso bo lakatsehang, ho sebetsa, le litlhoko tsa ts'ebetso tsa putty kapa plaster.
   • Etsa liteko tsa laboratori le liteko ho lekola phello ea litekanyetso tse fapaneng tsa MHEC ho thepa e kang viscosity, ho boloka metsi, le sag resistance.
   • Qoba ho sebelisa MHEC ho feta tekano kapa ho fokotsa tekanyetso, kaha chelete e ngata kapa e sa lekaneng e ka ama ts'ebetso ea putty kapa samente hampe.
3. Mokhoa oa ho kopanya:
   • Etsa bonnete ba hore MHEC e hasanngoa le ho fana ka metsi ka ho feletseng ka ho e kopanya ka mokhoa o ts'oanang le lisebelisoa tse ling tse omeletseng (mohlala, samente, li-aggregates) pele u eketsa metsi.
   • Sebelisa lisebelisoa tsa ho kopanya mechine ho finyella ho hasana ho tsitsitseng le homogenous ea MHEC ho pholletsa le motsoako.
   • Latela mekhoa e khothalletsoang ea ho kopanya le tatellano ea ho ntlafatsa ts'ebetso ea MHEC ka putty powder kapa plastering powder.
4. Ho lumellana le Li-additives tse ling:
   • Nahana ka ho lumellana ha MHEC le lisebelisoa tse ling tse atisang ho sebelisoa ha ho etsoa li-putty le samente, tse kang li-plasticizers, li-air-entraining agents, le li-defoamers.
   • Etsa liteko tsa ho lumellana ho lekola tšebelisano lipakeng tsa MHEC le li-additives tse ling le ho netefatsa hore ha li ame ts'ebetso ea tse ling hampe.
5. Boleng ba Lisebelisoa tse tala:
   • Sebelisa lisebelisoa tse tala tsa boleng bo holimo, ho kenyeletsoa MHEC, samente, li-aggregates le metsi, ho netefatsa ts'ebetso e tsitsitseng le boleng ba putty kapa plaster.
   • Khetha MHEC ho tsoa ho barekisi ba tsebahalang ba tsebahalang ka ho etsa li-cellulose ethers tsa boleng bo holimo tse fihlelang litekanyetso le litlhaloso tsa indasteri.
6. Mekhoa ea Ts'ebeliso:
   • Ntlafatsa mekhoa ea ts'ebeliso, joalo ka ho kopanya, mocheso oa kopo, le maemo a ho folisa, ho eketsa ts'ebetso ea MHEC ka putty powder kapa plastering powder.
   • Latela mekhoa e khothaletsoang ea kopo e fanoeng ke moetsi oa MHEC le sehlahisoa sa putty/plaster.
7. Taolo ea Boleng le Teko:
   • Ho kenya ts'ebetsong mekhoa ea ho laola boleng ho shebella ts'ebetso le ts'ebetso ea li-putty kapa li-plaster formulations tse nang le MHEC.
   • Etsa tlhahlobo ea khafetsa ea thepa ea bohlokoa, joalo ka viscosity, ts'ebetso, ho khomarela le litšoaneleho tsa ho folisa, ho netefatsa hore ho latela litlhoko tsa ts'ebetso le litlhaloso.

Ka ho nahana ka lintlha tsena ka hloko le ho kenya ts'ebetsong mekhoa e nepahetseng ea ho ntlafatsa, o ka ntlafatsa ka katleho ts'ebetso ea putty powder le plastering powder ka MHEC, ho finyella thepa e lakatsehang le ho etsa bonnete ba hore liphetho tsa boleng bo phahameng likopong tsa kaho.
