Nekuda kwekuti bhitumini kongiri yakagadziridzwa nemiti yakagadziridzwa yave kugamuchirwa nevakawanda munharaunda, bhitumini yakagadziridzwa inotambirwawo nemusika. Mushure mekunge michina yakashandiswa kwenguva yakati, matambudziko akadaro anogara achiitika. Maitiro ekuita nemamiriro ekuti iyo yakagadziridzwa bhitumeni chirimwa inovharika kubva pakudonhedza iyo yakagadziridzwa zvinhu. Iyo yakagadziridzwa bhitumini chirimwa ndeye yakajairwa polymer zvinhu, iyo inonyatso nzwisisa shanduko yeambient tembiricha. Nekudaro, mushure mekushanda kwemiti yakagadziridzwa bhitumeni, tembiricha mutangi inonyunguduka iri pamusoro pe180 ℃, zviri nyore kuita kuti yakagadziridzwa bhitumene chirimwa chinamatire kune inodonha chute pamusoro peiyo spiral yekudyisa mudziyo, uye yakagadziridzwa asphalt yekuchengetera tangi ichaita. ita kuti zvinhu zvakagadziridzwa zvidonhe.

Parizvino, iyo yakagadziridzwa bhitumeni zvidyarwa pamusika zvinoiswa maererano nemaitiro ekugadzira. Magadzirirwo ayo ekugadzira ari intermittent modified bitumen kugadzira michina. Munguva yekugadzira, iyo demulsifier, asidhi, mvura, uye yakagadziridzwa bhitumini yekuchengetera tangi yakagadziridzwa zvinhu zvinosanganiswa mutangi yekusanganisa sipo, uye yozopombwa mumuchina wehupfu nebhitumini. Kana ichishandiswa mukugadzira matangi ekuchengetera bhitumini akagadziridzwa, zvinoenderana nematanho akasiyana ezvishandiso zvakagadziridzwa, pombi yakagadziridzwa yebhitumini inogona kubatana kumberi kana kumashure kweiyo micro-upfu muchina, kana hapana yakatsaurirwa yakagadziridzwa bhitumini pombi yekuchengetera tangi. , asi huwandu hunodiwa hweakagadziridzwa bhitumini yekuchengetedza tangi inowedzerwa nemaoko kune sipo tangi. Kune iyo semi-rotary yakagadziridzwa bhitumini yekuchengetera tangi, chokwadi, iyo yakagadziridzwa yakagadziridzwa bhitumini tangi inoshongedzerwa ne sipo yekusanganisa sipo, kuitira kuti sipo igone kusanganiswa zvakasiyana kuti ive nechokwadi chekuti sipo inoramba ichitumirwa kumuchina wehupfu. Parizvino, huwandu hukuru hweemulsified bhitumini michina yekugadzira mune yakagadziridzwa yakagadziridzwa bhitumeni zvirimwa ndeyemhando iyi.
Iyo homogenizer uye pombi yekuendesa mune yakagadziridzwa yakagadziridzwa bhitumini chirimwa, pamwe nemamwe mota, agitators, uye mavharuvhu anofanirwa kuchengetedzwa zuva nezuva. Iyo homogenizer inofanirwa kucheneswa mushure mekuchinja kwega kwega kweakagadziridzwa bhitumini yekuchengetedza tangi. Iyo inoshanduka yekumhanyisa pombi inoshandiswa kugadzirisa kuyerera kweiyo yakagadziridzwa bhitumini yekuchengetedza tangi inofanirwa kugara ichiongororwa kuti ndeyechokwadi, uye inogara ichigadziriswa uye kuchengetedzwa. Iyo stator-to-stator clearance yemiti yakagadziridzwa bhitumeni inofanirwa kuongororwa nguva dzose. Kana iyo diki yemvumo inodiwa nemichina haigone kudarika, rotor inofanira kutsiviwa. Kana tangi rekuchengetera bhitumini rakagadziridzwa risisashandiswe kwenguva yakareba, mvura iri mutangi nepombi inofanira kudhirwa, chivharo chepuragi chega chega chinofanira kuvharwa zvakasimba, chichengetedzwe chakachena, uye chimwe nechimwe chekushandisa chinofanira kuzadzwa girizi. Kana iyo yakagadziridzwa asphalt yekuchengetedza tangi inoshandiswa kamwe chete uye isingashandisi kwenguva yakareba, ngura mutangi inofanira kubviswa painovhurwa, uye sefa yemiti yakagadziridzwa yakagadziridzwa bhitumeni inofanira kucheneswa nguva dzose.
