Mumakore achangopfuura, nekukura kuri kuramba kuchisimba kwemadziro ezvekunze kwekunze
Kuti uwedzere kuongorora maitiro echiitiko pakati peHPMC uye SEENT-BASA REMAHARA, Pepa iri rinotarisa pane iyo yekuvandudza mhedzisiro yeHPMC pane inogadzirisa zvinhu zvezvivakwa zve coment-based midziyo.
kutenderedza nguva
Nguva yekugara yekongiri inonyanya kuenderana nenguva yekuita simende, saka nguva yekufamba-famba ichishandiswa nemvura isingabvumirwe nemvura. ratio uye mongwe ratio yemutyairi.
Zvinoenderana nekuedzwa, kuwedzera kweHPMC kune kukosha kwakakosha pamusanganiswa wegweya, uye nguva yekugara yemota inowedzera zvinotevera nekuwedzera kweHPMC zvemukati. Pasi peiyo hpmc yezvinyorwa, iyo pasi pemvura yakaumbwa mongwe inokurumidza kupfuura iyo motsi yakaumbwa mumhepo. Iyo nguva yekugara yepakati pekuumbwa kwayo kwenguva refu. Kana akayerwa mumvura, achienzaniswa neisina kufungidzira, iyo nguva yekufungidzira yakasanganiswa neHPMC inononoka ne 6-18 maawa ekutanga kurongedza uye maawa makumi matanhatu nemashanu ekupedzisira kurongeka. Naizvozvo, HPMC inofanira kushandiswa mukubatanidzwa nevanowedzera.
HPMC ndeye yakakwira-molecular polymer ine macromolecular mutsara uye hydroxyl boka pane iro rinoita boka, iro rinogona kuumba hydrogen zvishamiso nemamolekora emvura uye kuwedzera zvevhu emvura yemvura yekusanganisa. Maketani akareba eHPMC anokwezva mumwe nemumwe, achigadzira iyo HPMC mamorekuru entangle inopinda mumwe nemumwe kuti iite chimiro chetivhi, kuputira simendi uye kusanganisa mvura. Sezvo HPMC inoumba dhizaini yakafanana nefirimu uye inoputira simende, ichaita zvinobudirira kusungwa kwemvura mumuti, uye kudzora kana kudzora huwandu hweiyo simende.
Kubuda ropa
Phenoming phenomon yemota yakafanana neyakajairwa nekongiri, inokonzeresa kuwanda kwemvura yekuputika kwemvura, uye kunyange kupaza, uye simba rezvipenga zvevhu rakapusa.
Kana iyo Dosage iri pamusoro 0.5%, hapana chikonzero chekubuda ropa. Izvi zvinodaro nekuti HPMC yakavhenganiswa mumutumbi, HPMC ine mapoka efirimu uye network mapoka ehuremu Mushure mekuwedzera hpmc kune dhiri, akawanda akazvimirira madiki emhepo mabhuru emhepo anoumbwa. Aya mabhuru emhepo anogovaniswa zvakanyanyisa mudhaka uye anotadzisa kuiswa kweakakwikwidza. Kuita kwehunyanzvi kweHPMC kune simba rakakura pane simende-yakavakirwa zvinhu, uye zvinowanzoshandiswa kugadzirira zvinhu zvitsva zveComent zvakadai sePolymer Dound uye Polymer Doundt, kuitira kuti ive nekuchengetwa kwemvura uye kupururudza kwemvura.
MOTOR YEMVURA FAND
Kana huwandu hweHPMC idiki, ine pesvedzero huru pane iyo mvura inodiwa yemutya. Panyaya yekuchengeta huwandu hwekuwedzera kweiyo moter Kana huwandu hweHPMC hwakaderera 0.025%, nekuwedzera kwehuwandu, iyo mvura yekudonha kuwanda kweHPMC iri diki, ine mvura-inoderedza mari, uye hpmc ine mhepo-yekupindirana nemhepo. Kune huwandu hukuru hwematumbi akazvimirira akazvimirira mhepo mudhiri, uye aya emhepo mabhuru anoita senge lubricant kuti uvandudze fluidity yeiyo flui Kana dosage yakakura kupfuura 0.025%, iyo mvura yekuda kwemotokari inowedzera nekuwedzera kweiyo dosage. Izvi zvinodaro nekuti iyo Network chimiro cheHPMC yakawedzera, uye musimboti pakati pehombodo pamatanho marefu inopfupiswa, iyo ine mhedzisiro yekukwezva uye kubatana, uye inoderedza iyo fleidiity yerudzi. Naizvozvo, pasi pemamiriro ekuti mwero wekuwedzera ndehwewewo, iyo slurry inoratidza kuwedzera kwekuda kwemvura.
01. Kupararira Kudzivisa bvunzo:
Anti-kupararira ndiyo yakakosha technical index kuyera mhando yeanti-kupararira mumiririri. HPMC ipoluke-soluble polymer inoenderana, inozivikanwa zvakare seye-soluble resin kana mvura-yakadzika-mvura polymer. Iyo inowedzera kuwirirana kwemusanganiswa nekuwedzera iyo visikoka yemvura yekusanganisa. Icho hydrophilic polymer zvinhu zvinogona kunyungudika mumvura kuti ugadzire mhinduro. kana kupararira.
Kuedza kunoratidza kuti kana huwandu hweNaphthalene-hwakanyanya hwekubudirira-kugona kugona zvakakura zvinowedzera, kuwedzera kwepamusoro-soro Izvi zvinodaro nekuti iyo naphthalene-yakavakirwa yakakwira-kugona kwemvura kuderedza inoderedza. Kana kuderedza kwemvura kunowedzerwa kune dhiragi, iyo yekudzora mvura ichave yakatungamirwa pamusoro pechikamu chechikamu chekugadzira pamusoro peiyo nzvimbo yemasimende ine iyo imwecheteyo. Uku kudzora kwemagetsi kunoita kuti smenments scement inoumba chimiro chekusimara chakashambidzwa, uye mvura yakaputirwa muchimiro ichiburitswa, iyo ichaita kuti kurasikirwa nechikamu cheiyo simende. Panguva imwecheteyo, inowanikwa kuti nekuwedzera kweHPMC zvemukati, kupatsanurana kudzikisira kweiyo nyowani yemukati motsi iri kuita zviri nani uye zviri nani.
02. Simba hunhu hwe kongiri:
Mune mutyairi wepanhamba purojekiti, hpmc pasi pemvura isiri-inoparadzanisa kongiri yekushambadzira yakaiswa, uye iyo dhizaini yegiredhi giredhi raive c25. Zvinoenderana nemubvunzo wekutanga, huwandu hwesimbe ndeye 400kg, iyo yakawedzera silica fume ndeye 0.42 fungidziro mumhepo ndeye 42.6mpa, iyo 28d avhareji simba repasi pemvura nehurefu hwe60mm is
03. Miedzo inoratidza:
. Nekuwedzera kweHPMC Zvemukati, iyo nguva yekuisa yemota inotambanudzwa zvakanyanya. Pasi peiyo hpmc yezvinyorwa, duri rakaumbwa pasi pemvura rinokurumidza kupfuura iro rakaumbwa mumhepo. Iyo nguva yekugara yepakati pekuumbwa kwayo kwenguva refu. Ichi chimiro chinobatsira pasi pemvura concrete pumping.

. Iyo fungidziro yakaumbwa pasi pemvura kwemazuva makumi maviri nemasere idiki crisp. Chikonzero chikuru ndechekuti kuwedzera kweHPMC kunoderedza zvakanyanya kurasikirwa uye kupararira kwesimendi paunenge uchikanda mumvura, asi zvakare inoderedza kuenzanisa kwesimende. Muchirongwa, pasi pemamiriro ekuita kuti uve nechokwadi chekusavimbika pasi pemvura, iyo Dosage yeHPMC inofanira kuderedzwa zvakanyanya sezvinobvira.
. Iyo puroyi yemutyairi inoratidza kuti simba retio yemvura-yakaumbwa kongiri uye mhepo yakaumbwa kongiri ndeye 84.8%, uye mhedzisiro yacho yakakosha.
