Kongiri yakareruka imhando yehuremu huremu hunyoro hunogadzirwa nekuwedzera kemikari inopupuma semendi mumarara uye kushandisa kemikari yayo kuita gasi., nokudaro tichiunza nhamba huru yetubhuru tuduku mumatope.Nekuvandudzwa kwekuvaka mitemo yekuchengetedza simba., Kongiri isingaremi senge foam kongiri ine yakakwirira yekupisa conductivity, kunyange zvazvo isingapindi moto, izvo zvinotungamira kune zvishoma nezvishoma kuwedzera kwe insulation board dhizaini ukobvu, nyore kugadzira dhiramu risina chinhu, serious insulation layer inodonha, kuputika kwekunze kwekudzivirira, seepage, kudonha uye mamwe matambudziko emhando.
Sechinhu chakareruka chakasimba, airgel ine thermal conductivity isingasviki 0.013 W/(m•K), inova imwe yemidziyo ine yakaderera thermal conductivity mumunda wekupisa kwekushisa. Airgel pachayo haibatike uye ine yakanakisa kudzivirira moto.
Nzira yekugadzirira kwekongiri yakareruka ndeyotevera: 1. Wedzera mvura, uye airgel, fiber, mvura inoderedza, etc. Kupararira zvakaenzana, wobva wawedzera simende, kurudzira 2 min ~ 3 min kusvika yunifomu, pakupedzisira wedzera coagulant, foaming agent, kurudzira 20 s~30 p, make paste;(3) step 2 yakagadzirwa namatidza mu mold, stop 4 h ~ 6 h kubvisa mold, 24 h mushure mekucheka.
1. Kupesvedzera kwemukati meairgel pane inooneka density yekongiri isingaremi
Iyo stacking density yeairgel yakaderera kwazvo, uye kuwedzerwa kweiyo yakananga musanganiswa kuchaderedza zvakanyanya kuoneka density yeinorganic foaming insulation board., zvichikonzera kudzikira kukuru kwesimba rekumanikidza uye zvimwe zvinhu.Kuburikidza nekugadzirisa dosage yefoaming agent., furo kureba rinosvika 1 m3 kana yakakwirira zvishoma kupfuura 1 m3, sezvo dosage ye airgel inowedzera zvishoma nezvishoma, zvishoma nezvishoma kuderedza kuyerwa kwefuro agent, vimbisa hurefu hwefuro hunoenderana, saka density inooneka inoshandura kushoma kugadzirira kongiri isingaremi, nekuwedzera kweyero ye airgel kunze, pa cubic mita ye lightweight kongiri inowedzera zvishoma, uremu hwekugadzirira kwehupfu hwekongiri yakareruka inooneka density inowedzerawo zvishoma.
2.Mhedzisiro yemukati yeairgel pane inopisa conductivity yekongiri isingaremi
Nekuwedzera kweiyo airgel yemukati, thermal conductivity yekongiri isingaremi inotanga kuderera uye yobva yawedzera. Kana iyo airgel yemukati iri 120 L/m3, thermal conductivity inosvika 0.056 W/(m•K) padikidiki.Nekuwedzera zvishoma nezvishoma kweairgel content, iyo stacking density ye airgel yakaderera kwazvo. Kuti ive nechokwadi chehumwe hunoenderana nehurefu hwekupupa, izvo zviri mukati meiyo furo agent zvinodzikira zvishoma nezvishoma, uye porosity ye lightweight concrete inoderera zvishoma nezvishoma.Kana zviri mukati airgel zvakaderera, kudzikiswa kwezviri mukati me furo agent kunoderedza huwandu hwema pores akaunzwa mu lightweight kongiri, inovandudza porosity kugadzikana kwekongiri isingaremi, uye inowedzera yakavharwa porosity mwero. Panguva imwe, kuwedzerwa kweairgel kunoderedza kuwanda kwepore wall material, inovandudza kushanda kwayo kwekushisa kwekushisa, uye inowedzera kuderedza kupisa kwekushisa.Sezvo zvinyorwa zve airgel zvinoramba zvichiwedzera, huwandu hwemapores mune lightweight kongiri inoderera zvakanyanya uye ukobvu hwepore madziro hunowedzera. Kana kuvandudzwa kweaerogel's thermal insulation performance pamadziro epore hakusi nani pane kuwedzera kwekupisa kwekushisa kunokonzerwa nekuderera kwehuwandu hwema pores., the thermal conductivity inoshanduka kubva pakuderedzwa kusvika pakuwedzera.
3. Kupesvedzera kwemukati meairgel pamvura kunyudzwa kweinorganic foam insulation board
Nekuwedzera kweiyo airgel yemukati, mwero wekutora mvura wekongiri isingaremi unoderera zvishoma nezvishoma. Mwero wekutora mvura wekongiri isingaremi pasina airgel ndiyo 9.5%, nepo iyo yekongiri isingaremi ine airgel zvirimo 200 L/m3 ndizvo 7.4%, iyo inoderera neinopfuura 20%.Ongororo yezvikonzero zvayo inosanganisira zvinhu zvitatu zvinotevera: (1) airgel ine hydrophobicity yakasimba, kuderedza kutorwa kwemvura kwezvinhu;(2) mushure mekuwedzera kwe airgel, zviri mukati me furo agent inodzikira, iyo inovandudza porosity kugadzikana kwekongiri isina kuremerwa uye inowedzera iyo obturation rate.(3) nekuwedzera kweiyo airgel content, nhamba ye lightweight concrete pores yakaderera, kukora kwemadziro egomba kwakawedzera, inogona kudzivirira nani kunyorova mukati meiyo lightweight kongiri yemukati pores.
4. Kupesvedzera kwemukati meairgel pane inomanikidza simba reinorganic foaming insulation board
Nekuwedzera kweiyo airgel yemukati, simba rekumanikidza rekongiri isingaremi rinotanga rawedzera uye rozodzikira. Kana iyo airgel yemukati iri 80 L/m3, simba rekumanikidza rinosvika pakakwirira 0.60 MPa. Kusiyana kwemaitiro esimba rekumanikidza kunopesana neiyo yekupisa conductivity.Zvakanakira zvesimba rekumanikidza zvinosanganisira: (1) mushure mekuwedzera airgel, zviri mukati me furo agent inodzikira, kuvandudza kugadzikana kwestomatal kwekongiri isingaremi, kuwedzera kwayo obtuation rate, uye kuderedza chikamu chekutsemuka kwegomba nekupinza.(2) nekuwedzera kweiyo airgel content, nhamba yemapores ekongiri isingaremi inoderera uye kukora kwemadziro emadziro kunowedzera.Zvakaipa zvesimba rekumanikidza zvinosanganisira: (1) airgel kubatanidzwa kunoderedza density ye pore madziro zvinhu, zvichikonzera kudzikira kwekubereka kwepore wall materials, uye (2) airgel incorporation inokonzera kuwedzera kwekushandiswa kwemvura.Apo zvinyorwa zve airgel zvaive zvakaderera, zvinhu zvakanaka zvakaita basa guru uye simba rekumanikidza rakawedzera. Zvisinei, nekuwedzera kwemukati we airgel, pesvedzero yezvinhu zvisina kunaka yaive yakakura kupfuura yezvakanaka zvinhu uye simba rakadzikira zvishoma nezvishoma.
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.
