[1]. EVA yakagadziridzwa bhitumini EVA ine kuenderana kwakanaka nebhitumini uye inogona kunyungudutswa nekuparadzirwa mubitumeni inopisa isina colloid mill kana high-shear mechanical processing, zvichiita kuti zvive nyore kushandisa.
Mumakore achangopfuura, zvirongwa zvekupakwa kwebhitumini muAfrica zvave zvichishandiswa kakawanda, saka vamwe vemumba vanoyeuchidzwa kuti vateerere.
[2]. High viscosity, yakakwirira elasticity uye yakakwirira kuoma yakagadziridzwa bhitumini. Iyo bhitumini viscosity uye kuoma bvunzo inonyanya kukodzera SBR yakagadziridzwa bhitumini, asi kana ichishandiswa yakakwirira viscoelastic yakagadziridzwa bhitumini, kudhirodha kunowanzoitika, zvichiita kuti bvunzo isagone. Nekuda kweizvi, zvinokurudzirwa kushandisa muchina wekuyedza wepasirese kuitisa viscosity uye kuomarara bvunzo yeyakanyanya viscoelastic yakagadziridzwa bhitumeni, kurekodha kushushikana-kunetseka curve, uye kushandisa nzira yekubatanidza kuverenga zviri nyore mhinduro dzebvunzo. 3. High-content rubber composite modified bitumen Nekabhoni peak uye kuumbwa kwezvinangwa zvekusarerekera kabhoni, kuchengetedza simba uye kuderedza kubudiswa kwakakosha. Indasitiri yematayi yakatarisana nedambudziko re "kugadzirwa kwakawanda uye tsvina yakawanda" kubva payakagadzirwa nekugadzira. Matai anoda kushandiswa kwakananga kana kusina kunanga kwezviwanikwa uye simba kubva mukugadzirwa kusvika pakuraswa, zvichikonzera huwandu hukuru hwekabhoni dhaikisaidhi.
Chinhu chikuru chematayi kabhoni, uye kunyange matai akaraswa ane zvinopfuura 80% kabhoni. Matai anorasa anogona kudzoreredza huwandu hwakakura hwezvinhu uye simba, kugadzirisa kabhoni muzvigadzirwa, uye kuzadzisa chinangwa chekuchengetedza simba uye kuderedza emission. Matai anorasa zvinhu zvepolymer elastic izvo zvakaoma zvikuru kudzikisira. Vane elasticity yakakwira uye kuoma uye hapana shanduko yemuviri kana kemikari inoitika mukupisa kwe -50C kusvika 150C. Naizvozvo, kana vakatenderwa kushatisa zvakasikwa muvhu, ivo vanozoita Pasina kukanganisa mwero wekukura kwechirimwa, iyo nzira inogona kutora anenge 500 makore. Nhamba huru yematairi anoraswa anotutirwa zvisina tsarukano uye anotora nzvimbo yakawanda, kudzivirira kushandiswa kunobudirira kwezviwanikwa zvevhu. Uyezve, kuungana kwenguva refu kwemvura mumatai kuchabereka umhutu uye kuparadzira zvirwere, zvichikonzera ngozi dzakavanzika kuutano hwevanhu.
Mushure mekupwanya matai emarara kuita mupfudze werabha, bhitumene yakakwira-ine rabha yakagadziridzwa (inozonzi bhitumeni yerabha) inogadzirwa pakugadzira mugwagwa, kuona mashandisirwo ezviwanikwa, kunatsiridza mashandiro emugwagwa, kuwedzera hupenyu hwemugwagwa zvakanyanya, uye kuderedza mutengo wemigwagwa. . Construction Investment.
[3]. Sei iri "high-content rabha compound modified bitumen"?
Low tembiricha crack resistance
Rabha iri mumarara tire rabha poda ine yakafara elastic tembiricha yekushanda, saka musanganiswa webhitumini unogona kuramba uchichengetedza yakanyunguduka yekushanda munzvimbo yakaderera tembiricha, kunonoka kuitika kwekudzika-tembiricha kutsemuka, uye kudzikamisa-tembiricha yerabha poda mu. bhitumini, iyo inonyanya kuwedzera viscosity yebhitumini, iyo inowedzera kunyorova uye inovandudza zvikuru kugadzikana kwepamusoro-kugadzikana kwebhitumini nemisanganiswa. Iyo anti-skid uye ruzha-inoderedza kutsemuka-graded bhitumeni musanganiswa ine yakakura yechimiro kudzika uye yakanaka anti-skid kuita munzira yemugwagwa.
Bhitumini rerabha rinogona kuderedza ruzha rwekutyaira ne3 kusvika ku8 decibel uye rinogara zvakanaka. Waste tire rubber powder ine antioxidants, heat stabilizers, light shielding agents uye carbon black. Kuwedzera bhitumini kunogona kunonoka zvikuru kukwegura kwebhitumini uye kuvandudza kunaka kwemusanganiswa. Kugara uye kubatsira mumagariro e10,000 matani ebhitumini yerabha inoda kudyiwa kweanosvika zviuru makumi mashanu matai emarara, kuchengetedza 2,000 kusvika ku5,000 matani ebhitumeni. Mwero wetsvina yekudzokorodza chiyero chakakwira, simba rekuchengetedza uye kuchengetedzwa kwezvakatipoteredza riri pachena, mutengo wakaderera, nyaradzo yakanaka, uye elastomer pavement yakasiyana nedzimwe nzira. Zvichienzaniswa nekugadzikana uye kunyaradza, zviri nani.
Carbon dema inogona kuchengetedza ruvara rutema rwenzira yemugwagwa kwenguva yakareba, nekusiyana kwepamusoro nemakaki uye yakanaka yekuona induction. 5. Bitumen rock modified bitumen oil yakapfuura mazana emamiriyoni emakore ekuchinja kwesedimentation mumapako ematombo. Inoita shanduko mukupisa, kudzvanywa, oxidation, uye kunyungudika. Bitumen-senge zvinhu zvinogadzirwa pasi pekuita kwakasanganiswa kwe media uye mabhakitiriya. Imhando yebhitumini yechisikigo. Mamwe mabhitumu echisikigo anosanganisira bhitumini yegungwa, bhitumini yepasi pemvura, nezvimwe.
Mushonga weKemikari: Huremu hwemamorekuru hweasphaltenes mudombo rebhitumini hunotangira pazviuru zvakati kusvika kuzviuru gumi. Kemikari yeasphaltenes ndeye 81.7% carbon, 7.5% hydrogen, 2.3% oksijeni, 1.95% nitrogen, 4.4% sarufa, 1.1% aluminium, uye 0.18% silicon. uye dzimwe simbi 0.87%. Pakati pavo, zviri mukati kabhoni, hydrogen, okisijeni, nitrogen, uye sarufa zvakati wandei. Anenge ese macromolecules easphaltene ane polar anoshanda mapoka ezviri pamusoro, izvo zvinoita kuti ibudise yakanyanya kusimba adsorption simba pamusoro pedombo. Chizvarwa uye mavambo: bhitumini yedombo inogadzirwa mumitswe yematombo. Iyo hupamhi hwekutsemuka yakanyanya kutetepa, gumi chete masendimita kusvika kumamita akati wandei, uye kudzika kunogona kusvika kupfuura mazana emamita.

Sichuan Qingchuan Rock Bitumen: Yakawanikwa muQingchuan County, Sichuan Province muna 2003, yakaratidza matura anodarika miriyoni 1.4 matani uye anotarisirwa kuchengetedza anopfuura mamirioni makumi matatu ematani. NdeyeShandong Expressway.5. Mugodhi webhitumini wedombo wakawanikwa ne137th Regiment ye7th Agricultural Division yeXinjiang Production and Construction Corps muUrho, Karamay, Xinjiang muna 2001 ndiwo mugodhi wekutanga webhitumini wakawanikwa kuChina. Kushandiswa uye genre:
1. Isa zvakananga muhumburumbira hwekusanganisa bhitumini yekusanganisa chiteshi.
2. High modulus agent method, tanga wakuya poda, wobva wawedzera matrix bhitumene semugadzirisi.
3. Rubber powder kusanganisa
4. Kuparadzanisa jecha remafuta uye batanidza asphaltene content. 5. Batanidza nechiteshi chekusanganisa kuti uwedzere mazano matsva ekushandisa online:
1. Inoshandiswa kuchinjika base layer;
2. Inoshandiswa kugadzira migwagwa yekumaruwa;
3. Sanganisa nezvinhu zvakadzokororwa (RAP) kuitira kuvandudzwa kwemafuta;
4. Shandisa bhitumini activator kusanganisa bhitumini yemvura uye inotonhora sanganisa iyo pamusoro.
