Roj hmab-bitumen mastic yog ib qho khoom siv ntau yam, sib xyaw ntawm tar lossis roj bitumen. Raws li txoj cai, cov tshuaj xws li fibrous thiab pulverized fillers yog siv kom tau nws. Mastic tau txais nws qhov zoo ntawm cov cua sov ua haujlwm thiab hardness vim qhov nqus ntawm cov roj ntawm nws qhov chaw.
Cov khoom no muaj cov khoom xyaw hauv qab no:
- rubber;
- roj av bitumen;
- solvents;
- plasticizers.
Roj hmab-bitumen mastic yog siv los cais cov av hauv av thiab ntog ua los ntawm cov hlau, cov qauv, cov kav dej. Nws yog feem ntau siv hauv kev kho cov chav dej, loggias, hauv kev tsim cov qauv ntoo, pas dej ua ke. Mastic bituminous insulating tiv thaiv corrosion. Cov khoom no tsis muaj tshuaj lom cov kuab tshuaj thiab toluene.
Kev faib tawm
Cov khoom tuaj yeem ua tau los ntawm ntau yam nta. Muab hom kev khi cov ntsiab lus, muaj cov bituminous, bitumen-rubber, bitumen- polymer mastics. Nyob ntawm txoj kev siv, kub, txias, preheated rau ib tug predetermined kub yog cais, tsisyuav tsum tau cua sov, tab sis nrog ib tug ambient kub siab tshaj 5 degrees.
Qhov sib txawv tshaj plaws los ntawm lub hom phiaj. Roj hmab-bitumen mastic yog siv rau ntau lub hom phiaj: insulating, gluing, asph alt, anti-corrosion.
Daim ntawv thov
Yog tias koj teem koj tus kheej lub hom phiaj ntawm gluing dov cov ntaub ntawv uas yuav siv rau waterproofing los yog mounted rau ntau txheej vov tsev, ces nws yog zoo dua mus siv nplaum mastics. Tab sis muaj qee qhov nuances txog cov khoom siv vov tsev bituminous. Piv txwv li, roj hmab-bitumen mastic yog haum rau gluing rolls ntawm glassine los yog vov tsev cov ntaub ntawv. Yog tias lub ru tsev npog nrog cov khoom siv tsis tshua muaj zog, ces kev xaiv tar yog siv.
Thaum nws tsim nyog los tsim cov cam khwb cia los yog plaster waterproofing, los yog ib tug binder hom ntawm cov ntaub ntawv uas yuav tsum tau rau kev tsim cov boards, nws yog tsim nyog los siv insulating mastic.
Ntawm cov khoom loj (piv txwv li, cov qauv hydraulic) lossis rau kev ua kom cov dej tsis sib haum, siv cov khoom kub bitumen-mineral ntau yam. Nws yog tsim los ntawm tib bitumen nrog ntxiv ntawm ib tug ntxhia muab tub lim. Cov impurities no tuaj yeem muaj li ntawm 30 txog 64% (nyob ntawm qhov yuav tsum tau ua thiab cov xwm txheej).
Ua haujlwm nrog cov khoom
Cov roj hmab-bitumen mastic yog siv los ntawm kev siv tshuab hauv ob peb txheej. Qhov tshwm sim yuav tsum yog tag nrho cov tuab ntawm 10 millimeters. Ntau tshaj ib teev yuav siv sij hawm qhov txheej txheem. Ua tausiv thiab phau ntawv thov nrog txhuam los yog mob stroke, yog tias muaj qhov xav tau. Yog hais tias qhov kub thiab txias nyob ntawm 20 degrees rau 48 teev, qhov ziab kom tiav yuav tshwm sim rau lub sijhawm no. Yog tias qhov ntsuas kub qis dua 15 degrees, tom qab ntawd ua haujlwm nrog cov khoom siv no yog qhov tsis xav tau. Nyob rau hauv ib qho chaw kaw, nws yog ib qho tsim nyog los muab cov cua ntws zoo li qub. Nws yog ib qho tseem ceeb kom ua raws li kev tiv thaiv kev nyab xeeb, raws li cov mastics kub yuav tsum tau rhuab mus rau 180 degrees.
