Lightweight Concrete Additives | High-Performance Foaming Agents for Cellular Concrete
Foaming agent inoreva zvese zviri pamusoro-zvinoita zvinhu zvine mhinduro dzinogona kuburitsa furo rakawanda kuburikidza nemaitiro emuviri. (kubvongodza, mweya wakamanikidzwa, etc.) kana maitiro emakemikari pasi pemamiriro chaiwo. Foaming agent ine basa repamusoro pepamusoro, inogona kunyatso kuderedza kushushikana kwepamusoro pemvura, uye inoronga maviri-electron layer pamusoro pemvura firimu kuti itenderedze mhepo, kugadzira mabubbles, uyezve kugadzira furo nebubble rimwechete. Hunhu hweiyo inopupuma furo ibasa rayo repamusoro. Nemhaka yekushanda kwakanyanya kwepamusoro kweprotein pachayo, zvinokwanisika kugadzira furo mumiriri weprotein. Apo puroteni iri hydrolyzed, mapuroteni makuru mamorekuru echeni refu yepeptide anova musanganiswa weshort-chain inonyungudika madiki uye epakati mamorekuru.. Mushure mekunyungudika mumvura, inogona kugadzira colloidal mhinduro ine chaiyo viscosity. Iyo carboxyl, hydroxyl uye mamwe hydrophobic mapoka akadai akawedzera kabhoni ketani hydrocarbon mapoka, pamwe chete neasymmetry yemorekuru, kuderedza kushushikana kwepamusoro uye kukurudzira kuumbwa kweiyo interface.
Iyo peptide cheni dzeaya madiki uye epakati mamorekuru anotambanudzira pane interface, iyo yakasimba yehydrogen bonding pakati peboka rinogadzira mambure ekudzivirira akadzikama, iyo inosimbisa iyo interface, iyo inokurudzira kuumbwa uye kugadzikana kwefuro. Kusakwana hydrolysis yemapuroteni chinhu chakakosha mukuumbwa kwefuro uye kugadzikana. Kuenzaniswa neyechinyakare physio foaming agents, makemikari anopupuma vamiririri, uye synthetic surfactant foaming agents, iyo protein-based foaming agent ndeye yazvino-yekupedzisira-inopupa mumiriri ine kuita zvirinani uye zvirinani budiriro tarisiro.. Tichitarisa kubva kune general maitiro ebudiriro, yakatora chikamu chinowedzera chekunyorera mumakore achangopfuura. Kunyange zvazvo mutengo wayo wakanyanya kukwirira, ichiri kugamuchirwa nemusika nekuda kwekuita kwayo kwakanakisa, kuwana nyore kune zvigadzirwa, uye kuchengetedza kwezvakatipoteredza.
Chii chinonzi furo agent chinoshandiswa mukati furo kongiri?
(1) The chirimwa-based simende furo agent
Iwo makuru emhando dzechirimwa simende inopupuma maajenti ndiwo maviri akakosha makirasi etii saponin uye saponin. Mupfungwa yakasimba, chinhu chikuru chinoshanda chemhando mbiri idzi dzekupupa kwekongiri haisi protein asi yakafanana neyechinyakare yekugadzira furo.. Pane misiyano yakakura zvichienzaniswa neizvi. Besides, izvo zvinonyanya kusanganisa zveaya anopupa zvinhu zvinobva mumiti, saka vachiri kurongwa sechirimwa cheprotein foaming agents. Nekuda kwezvinhu zvakakwana mbishi, kugadzirwa uye kushandiswa kwemhando mbiri idzi dzesimende dzinopupa furo dzakasvika pamwero mukuru.
Chirimwa-chakavakirwa simende inopupuma mumiriri inoshandisa yakakwirira-yemhando yechirimwa chepolymer zvinhu semidziyo yakasvibirira uye inogadzirwa kuburikidza nekutevedzana kwakaomarara kuita kwemakemikari.. Chigadzirwa chacho chakachenuruka yero yakachena yakajeka ine mafuta mvura. Kusanzwa nemvura yakaoma, non-chepfu, isina hwema, hapana sediment. PH kukosha haina kwayakarerekera, simende isingaore, simbi, uye haisvibisi nharaunda. Iyo inoputira furo inodzivirira kuchengetedza, haisi nyore kushata, ine kuita kwefuro kwakanakisa, akapfuma mufuro, uye yakati dzikamei. Iko kunoshanda kweiyo inopupuma agent kugadzira foam simende ine zvakanakira kuderera kwekushandisa, mutengo wakaderera, uye yakasimba quality. Inoshandiswa zvakanyanya mumapurojekiti ekushongedza ekudziya kwepasi uye mapurojekiti ekushongedza padenga, iyo inogona kuchengetedza zvakanyanya mari yekuvaka.
(2) Protein-based foaming agent
Kuita kweprotein-based foaming agent yemhuka inofananidzwa neiyo yemapuroteni anopupuma echirimwa, uye kugona kupupa furo uye kugadzikana kwefuro kunowanzoenderana.Mapuroteni-akavakirwa furo emhuka akapatsanurwa muzvikamu zvitatu.: mahwanda emhuka ane hydrolyzed, hydrolyzed tsvina yemhuka bvudzi, uye hydrolyzed ropa gel. Mhuka simende inopupuma mumiriri inosarudzwa kubva kumhuka keratin uye inogadzirirwa kuburikidza neyakatevedzana ye hydrolysis maitiro., dissolution, dilution, kusefa, uye high-tembiricha shrinkage. Ichi chigadzirwa imvura yakasviba yakasviba viscous ine yakaderera tsvina yemukati, kunhuwa kwakanyanya, yunifomu quality, stable quality, kuumbwa kwakanaka, uye kugadzikana kwefuro. Nekuda kwesimba repamusoro uye kugadzikana kwefuro kwefuro pamusoro pevhu rakagadzirwa uchishandisa furo agent, iyo foam simenti inogadzirwa neanoita furo ine yakazvimirira yakavharwa mamiriro, uye mabubbles haataudzani nemabhuru. Zvigadzirwa zvesimende zvakafukidzwa zvine mutsindo wakanakisa wekupeta. Yayo imwe-nguva yekukanda foam simende inogona kusvika kupfuura 1.5m isina kudonha, iyo inokodzera kugadzirwa kwefoam concrete blocks, lightweight concrete panels, uye madziro ekuparadzanisa.
Zvakaipa zve mhuka simende inopupuma midziyo
Nekuda kwekuoma kwekugadzira maitiro, mutengo wechigadzirwa wakakwira. Foaming agents vane hufuro hwakaderera pane chirimwa chinopupa furo, uye simende ine furo inoshandiswa pakuwedzera kudyiwa. Pane chaiyo inonhuwa kana yashandiswa, uye ichanyangarika zvishoma nezvishoma pashure pokunge yaitwa simende inofuro.
Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvaga foaming-agent, ndapota inzwa wakasununguka taura nesu.
