Yuav ua li cas yog roj hmab-bitumen mastic?

Roj Hmab-bitumen mastic - multicomponent hnyav, lub sib tov ntawm ib los yog roj av bitumen. Feem ntau, nws yog tau txais siv tshuaj xws li fillers, fibrous thiab pulverulent. Nws hardness thiab thermal stability zoo sealant acquires los ntawm haum rau nws saum npoo roj.

Tus qauv ntawm cov khoom no muaj cov nram qab no Cheebtsam:

• roj hmab;
• roj av bitumen;
• kuab tshuaj;
• fillers;
• plasticizers.

Roj Hmab-bitumen mastic ua hauj lwm pab cais tawm lub underground thiab av lug ntawm steel lug, pipelines. Nws yog feem ntau siv nyob rau hauv lub kho ntawm chaw, loggias, thaum tsim ntoo lug, dej da. Bituminous rwb thaiv tsev tiv thaiv cov corrosion. Qhov no cov ntaub ntawv uas muaj tsis muaj tshuaj lom kuab tshuaj thiab toluene.

kev faib

Cov ntaub ntawv uas yuav tsiag ntawv los ntawm ntau yam tshwm sim. Xav rau hauv daim ntawv ntawm cov txuas hais, muaj mastic asphalt, bitumen-roj hmab, bitumo-
polymer. Nyob ntawm seb tus qauv ntawm kev siv cais kub, txias, pre-rhuab mus rau ib tug predetermined kub, tsis txhob yuav tsum tau preheating, tab sis nrog cov mob ntawm ambient kub puag ncig siab tshaj 5 degrees.
Feem ntau ntau yam hom phiaj. Mastic asphalt-roj hmab yog siv rau ntau lub hom phiaj: kev rho tawm, attaching, asphalt, corrosion.

daim ntawv thov

Yog hais tias koj teem ib lub hom phiaj rau muab kuav los tiag ntaub ntawv yuav tsum tau siv rau waterproofing los yog mounted rau cov multilayer txheej ntawm lub-ru tsev, nws yog ib qhov zoo tshaj plaws los mus siv ib tug gluing mastic. Tab sis muaj ib co nuances txog cov nqeeb ntawm bituminous cov ntaub ntawv. Piv txwv li, rau tsevneeg yob ntawm ib daim ntawv los yog glassine haum roj hmab-bitumen mastic. Yog hais tias koj sib tshooj lub-ru tsev yog tsis raws li check cov ntaub ntawv uas, cov ntoo ib kev xaiv siv.

Nyob rau hauv lub rooj plaub uas nws yog tsim nyog los tsim ib tug cam khwb cia los yog plaster ntxooj xav tau kev pab astringent hom ntawm cov khoom rau qhov siv thiab ua cov phiaj, nws yog zoo dua rau siv ib insulating mastic.

Nyob rau hauv loj heev tej khoom (e.g., hydraulic lug) los yog rau sau cov pob qij txha waterproofing siv kub bitumen-mineral hom. Nws yog tsim los ntawm tib lub bitumen nrog rau qhov sib ntxiv ntawm ib cov mineral muab tub lim. Cov impurities yuav tsum yog los ntawm los ntawm 30 mus rau 64% (nyob ntawm seb cov kev cai thiab tej yam kev mob).

Ua hauj lwm nrog rau cov khoom

Thov roj hmab-bitumen mastic mechanized txoj kev nyob rau hauv ob peb khaubncaws sab nraud povtseg. Raws li ib tug tshwm sim, yuav tsum tau ib tug tag nrho thickness ntawm 10 millimeters. Nws kav ntev tshaj ib teev curing txheej txheem. Koj kuj siv tau phau ntawv daim ntawv thov nrog ib tug txhuam los yog mob stroke, yog hais tias muaj yog xws li ib tug yuav tsum tau. Yog hais tias tsis pub dhau 48 xuaj moos uas qhov ambient kub yuav nyob twj ywm nyob rau hauv 20 degrees, qhov no lub sij hawm yuav tsum tau kiag li qhuav. Yog hais tias qhov kub thiab txias hauv qab no yog qhov taw qhia 15 degrees, ces ua hauj lwm nrog cov khoom no yog heev undesirable. Lub kaw qhov chaw yog tsim nyog los muab tej flow cua. Kev nyab xeeb yog ib qho tseem ceeb, txij thaum lub kub mastic yuav tsum tau rhuab mus rau 180 degrees.
