1. Yam khoom siv
Nozzle tsim: Cov qauv, qhov loj thiab kev faib tawm ntawm lub nozzle txiav txim siab lub kaum sab xis thiab ntws tus nqi ntawm asphalt txau, uas cuam tshuam ncaj qha rau qhov sib xws.
Kev tswj xyuas qhov siab: Lub siab ruaj khov tuaj yeem ua kom ntseeg tau tias asphalt yog txau ntawm tus nqi ntws tsis sib xws, thiab kev hloov pauv siab tuaj yeem ua rau tsis sib xws.
Tank qauv: Tsim nyog lub tank tsim tuaj yeem ua kom cov dej ntws zoo ntawm asphalt thiab tsis txhob muaj kev sib txuam hauv zos cuam tshuam rau kev sib xws.
Stirring device: Zoo nplawm tiv thaiv asphalt nag lossis daus thiab cais, ua kom muaj kev sib xyaw ua ke, thiab txhim kho kev sib kis.
2. Cov yam ntxwv ua haujlwm
Tsav tsheb ceev: ceev dhau los yog qeeb qeeb yuav ua rau asphalt thickness tsis sib npaug, thiab nws yog ib qho tsim nyog yuav tsum tswj kom tsim nyog thiab tswj kom muaj kev sib tw ceev.
Kev nthuav dav qhov siab: Qhov kev ncua deb ntawm lub nozzle thiab txoj kev nto cuam tshuam rau kev faib cov asphalt. Siab dhau los yog qis dhau tsis haum rau kev sib kis tsis sib xws.
3. Cov khoom tseem ceeb
Asphalt viscosity thiab kub: viscosity hloov nrog kub, cuam tshuam rau fluidity, thiab qhov kub thiab txias yuav tsum tau tswj xyuas kom tsim nyog viscosity.
Asphalt muaj pes tsawg leeg thiab zoo: Asphalt nrog cov muaj pes tsawg leeg thiab ruaj khov zoo tuaj yeem txo qhov txhaws thiab tsis ruaj khov thiab txhim kho kev sib txuam.
