Melemo ea eona e kenyelletsa ho ba le boikoetliso, litšenyehelo tsa basebetsi le ho ntlafatsa ts'ebetso ea sebopeho. Ho fihlela litšobotsi tsena ho hloka taolo e nepahetseng ea motsoako Sehlopha sena sa Cellulose e bapala karolo ea bohlokoa ho phelisang thepa ea Rheology ea SCC, ho ntlafatsa litšobotsi tsa eona le tse tsamaeang.
Thepa le mesebetsi ea HPMC
Hydroxypropypropypropinyl Methylcelllulose (HPMC) ke motho ea se nang ionic, ea nang le metsi a qhibilihang ea metsi a tsoang cellulose. Theobotsi ea eona ea bohlokoa e kenyelletsa:
TLHOKOMELISO: HPMC e eketsa pono ea tharollo ea metsi, a ntlafatsa mofuta oa thixoftropic oa motsoako oa konkreite.
Ho Boloka Metsi: E na le bokhoni ba ho lema metsi a hloekileng, ba thusang ho boloka ho thuisa ka konkreite ka ho fokotsa mouoane oa metsi.
Kholiseho le bongoli: HPMC e ntlafatsa matloana pakeng tsa konkreite, e ntlafatsa thepa ea eona e kopaneng.
Ntlafatso ea botsitso: E tiisa ho emisoa ha lithuso ho kopanya motsoako, ho fokotsa ts'ebetso le ho tsoa mali.
Mesebetsi ena e etsa HPMC e eketsang lethathamo e tloaelehileng Scc, ha e bua ka khethollo e tloaelehileng ea ho tsoala
Karolo ea HPMC ka ho ikarola konkreite
1. Ntlafatso ea ho ba le ho ba teng
Ts'ebetso ea mantlha ea HPMC ho Scc ke ho ntlafatsa ts'ebetso ea eona ka ho eketsa viscooity ea motsoako. Phetoho ena e lumella Scc ho phalla habonolo ka boima ba eona, ho tlatsa foromo e thata ea tšebetso ntle le tlhoko ea ho kopanya. HPMC e tiisa hore konkraka e ntse e sebetsa ka linako tse telele, tse molemo haholo bakeng sa tšora tse kholo kapa tse thata.
Ho phatloha: HPMC e kenya letsoho thepa ea motsoako oa thixotropic, e e lumellang hore e lule e le mokelikeli o mongata ha o le tsoatswa. Boitšoaro bona bo tšehetsa litšobotsi tsa ho iphahamisa
TLHOKOMELISO: Ka ho laola pono, HPMC e thusa ho boloka ts'ebetso e ts'oanang ho pholletsa le motsoako, e netefatsa hore ha ho na thuso ea Scc.
2. Khokahano le taolo ea ho tsoa mali

Mmino oa Homogeneous: Matla a HPMC a ho eketsa pono ea paseka ea samente e fokotsa ho sisinyeha ha metsi le ho ba monya kotsing ea ho arola.
Maloetse a senyehileng a maloetse: ka ho boloka metsi mabapi le motsoako, HPMC e thusa ho thibela ho tsoa mali. Ho boloka metsi ka metsing ho boetse ho etsa hore mokhoa oa bohloeki o tsoela pele hantle, o ntlafatse nts'etsopele ea matla le ho tšoarella ha konkreiti.
3. Ho tsitsa ho hoholo
HPMC e kenya letsoho botsitsong ba SCC ka ho ntlafatsa bokhabane lipakeng tsa lintho tse ling ho kopanya motsoako. Bokhoni bona bo ntlafalitsoeng bo bohlokoa ho hlokomela kabo e ts'oanang le ho thibela ho etsoa ha matata kapa matheba a fokolang.
Bohlale: Kemiso ea HPMC e ntlafatsa tlamo e betere pakeng tsa siling ea sistimi le li-agg tse kopaneng, tse bakang motsoako o kopaneng o hanang ts'ebetso e kopaneng.
Matlafatso: HPMC e tiisa likokoana-hloko tsa konkreiti, e lumella esita le ho tsamaisa thepa le ho thibela ho thehoa ha Latian le tse ntle.
Phello ho thepa ea mochini
1. Matla a qobelloang
Tšusumetso ea HPMC e matla a hatellang ea SCC hangata e ntle. Ka ho thibela ho arola ha homogeneous, HPMC e thusa ho boloka botšepehi ba likokoana-hloko tsa konkrente, e lebisang litšobotsi tse ntle.
HYDERS: Ho Boloka Meetso ea Meetso ea ho Boloka Hyduterante e felletseng ea pokello ea sistimi, e kenya letsoho kholisong ea matrix e matla.
Tlokotsi ea junifomo: Thibelo ea ts'ebetso e hlahisoang ke ho ajoa ka har'a phetiso ea li-aggprigtion, e tšehetsang matla a mangata hape a fokotsa kotsi ea lintlha tse fokolang.
2. Ho tšoarella
Ts'ebeliso ea HPMC ho Scc e ntlafatsa ho netefatsa hore na o lokela ho netefatsa mofumahali le likokoana-hloko tse ngata.
Ho Fokotsoa ke ho ntlafatsoa ho ntlafatsa le ho fokotsoa ho fokotseha ho hojoa ha konkreite, ho ntlafatsa mabaka a tikoloho a kang ho akheha, le khaletso.
Qetetso ea Bongata: Thibelo ea mali le khetho e tiisa pheletso e tšoarellang le ho qeta nako e ngata ea ho e lahla le ho bala.

Katleho ea HPMC ka scc e ipapisitse le litekanyetso tsa eona le litlhokahalo tse khethehileng tsa motsoako. Litefiso tse tloaelehileng tsa litekanyetso tsa 0.1% ho isa ho 0.5% ea boima ba samente, ho latela thepa ea samente, ho latela thepa e lakatsehang le litšobotsi tsa likarolo tse ling motsoako.
Moralo oa Kopanya: Moralo o mo hlophisang o bohlokoa ho ntlafatsa melemo ea HPMC. Lintlha tse kang mofuta o akaretsang, litaba tsa samente le lingoloa tse ling le tse ling li lokela ho nkuoa ho fihlela teka-tekano ea ho tsoela pele, ho tsitsa le ho matlafala.
Ho lumellana: HPMC e tlameha ho tsamaisana le likhato tse ling tse sebelisitsoeng ho kopanya le fokotsa mathata a metsi a ka sekisang ts'ebetsong ea SCC.
HydroxypropypropypropinyL methylcelllulose (HPMC) e bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso ea konkreite ea ho ikatisa (SCC). Bokhoni ba eona ba ho fetola liketsahalo, ho ntlafatsa ho boloka metsi, mme ba tsitsipanya motsoako, ho kenyelletsa le ho qojoa, ho tsoa mali le ho boloka phallo. Ho kenyelletsa HPMC ho scc ho hlahisoa ka mokhoa o sebetsang, o tsitsitseng, le o tšoarellang, o tsitsitseng, le tse tšoarellang tsa konkreite le tse tšoarellang, tse tšoarellang, tse etsang hore e be ekeletsoa lits'ebetso tsa bohlokoa bakeng sa likopo tsa sejoale-joale. Boitšoaro bo nepahetseng le bo hlophisehileng bo bohlokoa ho laola melemo e felletseng ea HPMC, e netefatsa hore scc e kopana le merero e fapaneng ea ts'ebetso ea ts'ebetso.
