HPMC, kapa Hydroxypropyl Methylcellulose, ke motsoako oa bohlokoa mefuteng ea mabota.Ka tlhaloso e felletseng, ho bohlokoa ho akaretsa likarolo tse fapaneng, ho kenyelletsa le sebopeho sa eona sa lik'hemik'hale, karolo ea lebota la putty, melemo, lits'ebetso, le lintlha tsa ts'ebeliso.
1. Sebopeho sa Lik'hemik'hale le Thepa:
Hydroxypropyl Methylcellulose (HPMC) ke ea lelapa la cellulose ethers.Sebopeho sa eona se na le liketane tsa mokokotlo oa cellulose tse nang le hydroxypropyl le lihlopha tsa methyl tse khomaretsoeng.Sebopeho sena sa lik'hemik'hale se fana ka thepa e fapaneng ho HPMC, ho kenyelletsa:
Ho Boloka Metsi: HPMC e na le bokhoni ba ho boloka metsi, e leng ntho ea bohlokoa bakeng sa ho boloka botsitso bo nepahetseng ka har'a metsoako ea putty leboteng.
Thickening: E sebetsa e le ntho e teteaneng, e tlatsetsang ho viscosity e lakatsehang ea putty.
Mosebetsi: HPMC e ntlafatsa ts'ebetso ka ho ntlafatsa ho ata le ho fokotsa ho fokotseha nakong ea ts'ebeliso.
Ho tlama: E thusa ho kopanya likarolo tse ling tsa putty, e leng se etsang hore ho be le ntlafatso e tiileng ho li-substrates.
2.Ka har'a li-putty formulations, HPMC e sebeletsa merero e mengata:
Taolo ea Consistency: E thusa ho boloka botsitso bo lakatsehang ba putty nakong eohle ea ts'ebeliso ea eona, ho netefatsa tšireletso e boreleli le e ts'oanang.
Ho boloka Metsi: Ka ho boloka metsi ka har'a motsoako, HPMC e thibela ho omisoa pele ho nako, ho lumella nako e lekaneng ea kopo le ho folisa.
Ntlafatso ea Adhesion: HPMC e ntlafatsa ho khomarela ha lebota la putty ho li-substrates tse fapaneng tse kang konkreite, samente, le bokaholimo ba masonry.
Crack Resistance: Thepa ea eona e tlamang e kenya letsoho ho matla a kakaretso a putty, e fokotsang monyetla oa hore mapetsong a be teng ha o omisoa.
3.Melemo ea HPMC ho Wall Putty:
Tšebeliso e Ntlafetseng: HPMC e netefatsa ts'ebeliso e bonolo le ho hasana ha lebota la putty, esita le holim'a tse otlolohileng, ho fokotsa boiteko ba basebetsi.
Tšebeliso e Matlafalitsoeng: Tšebeliso ea HPMC e ntlafatsa ho tšoarella le nako e telele ea lesela la putty ka ho fokotsa ho fokotseha le ho phunyeha.
Ho hanyetsa Metsi: HPMC e thusa ho hanela ho kenella ha metsi, ka hona e sireletsa karolo e ka tlase ho tšenyo e amanang le mongobo.
Ho lumellana: E lumellana le mefuta e mengata e fapaneng ea li-additives le li-pigments tse atisang ho sebelisoa ha ho etsoa li-putty tsa lebota, tse lumellang hore ho be le mefuta e mengata ea moralo oa lihlahisoa.
Ts'ebetso e tsitsitseng: HPMC e fana ka litšobotsi tse ts'oanang tsa ts'ebetso ho putty ea lebota ho pholletsa le maemo a fapaneng a tikoloho le maemo a ts'ebeliso.
4.Wall putty formulations e nang le HPMC e fumana lits'ebetso tse ngata ho:
Libaka tsa Lerako tse ka hare le tsa ka ntle: li sebelisetsoa ho bebofatsa le ho lekanya bokaholimo ba mabota pele ho penta kapa ho etsa wallpaper, ho fana ka motheo o tšoanang.
Tokiso le Tlhokomelo: Wall putty e nang le HPMC e sebelisoa bakeng sa ho lokisa mefokolo e menyenyane le mapetsong, ho khutlisetsa botle ba mabota.
Liqeto tse Khabisitsoeng: Li sebetsa e le motheo oa likhabiso tse khabisitsoeng, tse nolofalletsang ts'ebeliso ea mefuta e fapaneng ea masela le liphahlo bakeng sa ntlafatso ea botle.
5.Leha HPMC e fana ka melemo e mengata, ts'ebeliso ea eona e sebetsang e hloka ho ela hloko lintlha tse itseng:
Tekanyetso e nepahetseng: Tekanyetso e nepahetseng ea HPMC e tlameha ho khethoa ho latela litlhoko tse ikhethileng tsa sebopeho sa lebota la putty, ho nahanoa ka lintlha tse kang ho lumellana ho lakatsehang le maemo a kopo.
Teko ea Kamano: Ho lumellana le lisebelisoa tse ling le li-additives ho lokela ho netefatsoa ka tlhahlobo ea laboratori ho netefatsa ts'ebetso e lakatsehang le botsitso ba sehlahisoa sa ho qetela.
Netefatso ea Boleng: Ho bohlokoa ho fumana HPMC ea boleng bo holimo ho tsoa ho barekisi ba tsebahalang ho netefatsa botsitso le ho ts'epahala ha liforomo tsa putty leboteng.
Ho boloka le ho Ts'oara: Maemo a nepahetseng a polokelo, ho kenyelletsa le ts'ireletso ho tloha mongobo le ho pepesehela mocheso o feteletseng, ke tsa bohlokoa bakeng sa ho boloka bots'epehi ba HPMC le ho ntlafatsa bophelo ba eona.
Hydroxypropyl Methylcellulose (HPMC) e na le karolo ea bohlokoa mefuteng ea li-putty tsa lebota, e fana ka mefuta e mengata ea melemo e kang ho sebetsa hantle, ho tšoarella, le ho khomarela.Tšebeliso ea eona e masene, hammoho le ho nahanisisa ka hloko ka litlhoko tsa tlhahiso le maemo a kopo, ho kenya letsoho ho nts'etsopele ea lihlahisoa tse phahameng tsa lebota tse sebetsang hantle bakeng sa lits'ebetso tse fapaneng tsa kaho le tlhokomelo.
