Ntau tus neeg uas, tsis hais hauv lawv txoj haujlwm lossis ntiag tug, koom nrog kev tsim kho, paub zoo tias ICBM yog dab tsi. Tab sis qhov tseeb yog hais tias txog niaj hnub no, civil engineers tseem tsis tau paub yuav ua li cas los hloov cov bitumen-rubber muaj pes tsawg leeg. Nws yog siv thaum tsim lub ru tsev uas siv mastic, nrog rau thaum siv cov ntaub ntawv yob rau vov tsev.

Yog li, bituminous mastic MBR 65 tau ntawv pov thawj rov qab rau hnub ntawm USSR. Tab sis qhov no tsis tau txhais hais tias txij thaum ntawd los nws cov ntsiab lus tseem tsis tau hloov lossis hloov kho. Nws muaj ob hom - kua thiab tuab. Los ntawm nws tus kheej, nws yog roj av bitumen nrog additives ntawm muab tub lim thiab plasticizer. Qhov kawg, dhau los, muab nws cov khoom khov, uas ua rau nws yooj yim siv cov tshuaj rau lub ru tsev saum npoo.

Kev sib xyaw thiab qauv

Vim nws muaj pes tsawg leeg, bitumen-rubber mastic (MBR) sai sai ua ke nrog txhua yam ntaub ntawv. Yog li ntawd, nws tau ntim rau hauv cov thawv tshwj xeeb los tiv thaiv cov nplaum los yog lub hnab. Txhawm rau muab cov khoom tsim nyog plasticity, crumb roj hmab ntxiv rau nws.

siv qhov twg?

Mastic-raws li vov tsev tau muab tso rau ntawm txhua lub tsev ntau tsev niaj hnub no. Nws qhov zoo dua yog tias nws ua tiav tag nrho cov qhov khoob uas twb muaj lawm. Ua hauj lwm nrog mastic yog nqa tawm los ntawm preheating nws. Cov neeg uas paub dab tsi ICBM yog coj qhov tseeb rau hauv tus account, yog li lawv sov nws ua ntej. Nws softens kiag li ntawm qhov kub ntawm txog 90 ° C.

Ua ntej pib ua haujlwm, qhov chaw tau npaj. Ua li no, lub ru tsev yog ntxuav ntawm cov khib nyiab uas twb muaj lawm. Tsis tas li ntawd, ua ntej pib ua haujlwm ntawm lub ru tsev, lub ru tsev yog qhuav. Nyob rau hauv cov ntaub ntawv no, tshwj xeeb gas burners yog siv. Yog tias huab cua qhuav thiab kub sab nraud, qhov txheej txheem no tuaj yeem raug tshem tawm.

Daim ntawv thov nta

Ntxiv rau cov txheej txheem saum toj no ntawm daim ntawv thov, cov neeg uas paub tias ICBM tseem siv li cas thaum tso cov kav dej. Qhov tseeb yog tias MBR 65 muaj qhov muag muag ntau dua thiab yog li siv los cais cov qauv uas raug cuam tshuam los ntawm kev co. Nyob rau hauv tus txheej txheem ntawm mechanical deformation ntawm cov txheej txheem txheej txheem, mastic txheej yuav hloov nrog nws.

Tam sim no, tau txiav txim siab seb ICBM yog dab tsi, cia peb saib qee yam ntawm nws cov ntau yam.

Mastic MBR-100 yog siv thaum tso cov ntaub ntawv yob rau vov tsev, nrog rau kev sau cov dej tsis muaj dej. Tus naj npawb qhia nyob rau hauv nws cov cim qhia txog qhov kub thiab txias thaum softening tshwm sim. Tab sis tib lub sijhawm, nws tsim nyogNco ntsoov tias mastic yuav tsum tau rhuab mus txog 200 ° C. Tag nrho cov no tau ua tiav txhawm rau ua kom nws yooj yim rau siv rau ntawm qhov chaw pitched, nrog rau ntawm cov phab ntsa vertically.

Cov neeg uas tau paub ntev txog dab tsi bituminous mastic yog, tsawg kawg ib zaug ntsib xws li ntau yam xws li MBR-X. Ib tug feature ntawm cov khoom no yog tias preheating tsis yog yuav tsum tau rau nws siv. Qhov no yog ua tiav vim lub fact tias cov muaj pes tsawg leeg muaj xws li ib tug tshwj xeeb hnyav, uas, tom qab daim ntawv thov, evaporates spontaneously, thiab mastic hardens.
