Tšebeliso ea Hydroxypropyl Methylcellulose (HPMC) ho Meaho ea Grouting

Hydroxypropyl Methylcellulose (HPMC)ke ether ea cellulose e seng ea ionic, e sebelisoang haholo thepa ea kaho, haholo-holo thepa ea grouting e thehiloeng samente, e hohetseng tlhokomelo e eketsehileng. Jwalo ka sehlomathiso sa polymer se sebetsang hantle, HPMC e ka ntlafatsa haholo ts'ebetso ea kaho le ts'ebetso ea ho qetela ea thepa ea grouting, ea ntlafatsa ho boloka metsi, ho phalla ha metsi, ho tsitsa le ho khomarela, ka hona e netefatsa boleng ba kaho le polokeho ea boenjiniere.

1. Tlhaloso le litlhoko tsa ts'ebetso ea ho haha ​​​​grouting

Grouting ea meaho e sebelisoa haholo ho tlatsa likheo lipakeng tsa likarolo tsa meaho, ho lokisa metheo ea lisebelisoa, ho lokisa liphoso tsa meaho, ho koala mapetso, jj. Lisebelisoa tse tloaelehileng tsa grouting li kenyelletsa lisebelisoa tsa grouting tse thehiloeng samente, lisebelisoa tsa grouting tse sa fokotseng, lisebelisoa tsa grouting tse fetotsoeng ka polymer, jj. Litlhoko tsa eona tsa ts'ebetso li kenyelletsa haholo:

Ho phalla hantle le thepa e phallang ka boyona, e le hore thepa ea grouting e ka tlatsa libaka tse rarahaneng kapa tse patisaneng hantle;

Ho boloka metsi haholo ho thibela ho fokotseha ha metsi le mapetso a bakoang ke tahlehelo ea metsi;

Ho khomarela le ho ntlafatsa matla ka nepo ho netefatsa hore ho na le tlamo e tiileng le motheo kapa litšepe;

Ho hanyetsa mapetso hantle le ho tšoarella ho fihlela polokeho ea sebopeho ea tšebeliso ea nako e telele.

Lisebelisoa tsa setso tsa grouting li sekametse ho se phalle hantle, ho arohana le ho dutla ha metsi, ho fokotseha le ho petsoha ha dikopo tse sebetsang, kahoo ho hlokahala ho kenya di-additives tse ntlafatsang tshebetso-HPMC.

2. Litšobotsi tsa ts'ebetso ea HPMC

HPMC ke ether e fetotsoeng ea cellulose e entsoeng ka cellulose ea tlhaho e nang le limolek'hule tse ngata ka karabelo ea etherification, e nang le litšobotsi tse latelang tsa bohlokoa:

2.1. Ho boloka metsi hantle

HPMC e ka boloka metsi ka katleho nakong ea ho monya samente, ea liehisa tahlehelo ea metsi, ea netefatsa hore samente e na le metsi a mangata, ea ntlafatsa matla a pele le ho fokotsa ho petsoha.

2.2. Ho phalla le ho tlotsa ho ntlafetseng

Ho eketsa tekanyo e loketseng ea HPMC ho ka ntlafatsa haholo ho phalla le ho boreleli ha thepa ea grouting, ho etsa hore ho be bonolo ho e tšela, ho e tlatsa le ho e thothomela.

2.3. Ho tsitsisa ho tsitsitseng le ho hanyetsa karohano

HPMC e bopa sebopeho sa marang-rang tsamaisong ea grouting, e tsitsisa kabo ea lerōle, 'me e thibela ho na ha likaroloana, karohano le ho tsoa ha metsi.

2.4. Tshebetso e ntlafetseng ya ho kopanya

Thepa ea eona ea ho etsa filimi le phello ea ho kolobisa holim'a substrate li ka ntlafatsa kamano pakeng tsa thepa ea grouting le libaka tsa motheo tse kang konkreite, litšepe tsa tšepe le majoe a majoe, le ho ntlafatsa botšepehi ba sebopeho.

2.5. Tshebetso e ntlafetseng ya kaho le nako ya tshebetso

HPMC e na le litlamorao tse ntle tsa ho boloka metsi le ho liehisa mosebetsi, tse thusang ho eketsa nako ea ho bula, ho ntlafatsa ho tenyetseha ha kaho, le ho ikamahanya le maemo a rarahaneng a kaho.

3. Phello ea ts'ebeliso ea HPMC ho meaho ea grouting

3.1. Tšebeliso ho lisebelisoa tsa motheo oa grouting

Ho kopanya motheo oa lisebelisoa ho hloka matla a maholo, ha ho na ho fokotseha, le ho phalla ho hoholo. Kamora ho eketsa HPMC, thepa ea ho kopanya e ka boloka ho phalla ho hotle ntle le ho eketsa karolelano ea metsi le samente, ho qoba ho tsoa mali le ho arohana, 'me ka nako e ts'oanang ho ntlafatsa bongata ba ho tlatsa ho netefatsa botsitso ba ts'ebetso ea nako e telele ea lisebelisoa.

3.2. Tšebeliso ea li-grouting tsa tokiso ea meaho

Ha ho lokiswa mapetso a mehahong ya konkreite kapa bokahodimo bo nang le mahe a dinotshi, thepa ya grouting e hloka ho boloka metsi a mangata le ho hokahana ho hoholo. HPMC e ntlafatsa ka katleho ho kopana ha thepa ya grouting le ho kgomarela ha yona bokahodimong ba motheo, ha ka nako e ts'oanang e laola ho nyenyefala le ho qoba ho petsoha ha bobedi.

3.3. Tšebeliso ho grouting ea duct e hatelletsoeng pele

Ho kenya diphaephe tse hatelletsoeng pele ho hloka hore seretse se be le metsi a mangata le thepa ea ho tlatsa ho thibela lesoba ho siuoa le se na letho le khoele ea tšepe ho senyeha. HPMC e ka thibela seretse ho lula le ho arohana, ea etsa bonnete ba hore seretse se tlala ka botlalo, le ho ntlafatsa ho tšoarella.

4. Litlhahiso tsa tšebeliso ea HPMC ho foromo ea grouting

Ha o sebedisa HPMC disebedisweng tsa grouting, mohlala le tekanyo di lokela ho kgethwa ka tsela e utlwahalang:

Khetho ea mohlala: Khetha sehlopha se loketseng sa viscosity (ka kakaretso 50,000~100,000 mPa·s) ho latela karolelano ea metsi le samente le litlhoko tsa kaho tsa sistimi ea grouting;

Chelete e ekelitsoeng: Hangata 0.1% ~ 0.5% ea boima ba samente, e ka ntlafatsoang ka liteko ho latela litlhoko tse itseng;

Mokhoa oa ho eketsa: HPMC e lokela ho qhalanngoa ka ho lekana ka har'a motsoako o omileng, ebe metsi a eketsoa bakeng sa ho kopanya le ho hlohlelletsa ho qoba ho kopana le ho ama phello.

Hydroxypropyl methylcellulose (HPMC), e le sehlomathiso sa moaho se sebetsang hantle haholo, e bapala karolo e ke keng ea nkeloa sebaka ho haheng thepa ea ho kopanya likhoele. Ha e ntlafatse feela ts'ebetso ea kaho le thepa ea mechini ea thepa ea ho kopanya likhoele, empa hape e ntlafatsa boleng ba ho kopanya likhoele le ho tšoarella ha boenjiniere. Ha merero ea kaho e ntse e tsoela pele ho ntlafatsa litlhoko tsa eona bakeng sa katleho ea kaho le boleng ba thepa, HPMC e tla sebelisoa le ho ntlafatsoa haholo lefapheng la ho kopanya likhoele le thepa e meng ea kaho. Bakeng sa bahlahisi ba thepa ea ho kopanya likhoele, ho tseba tšebeliso e utloahalang ea theknoloji ea HPMC e tla ba e 'ngoe ea linotlolo tsa ho ntlafatsa tlholisano ea mantlha ea lihlahisoa.
