Yintoni i-mastic ibhamum yebhanki?

I-mastic ye-rubber bituminous is a multicomponent mass, umxube we-tar okanye i-bitumen yeoli. Ngokuqhelekileyo, ngokusetyenziswa kwayo kusetyenziswa izinto ezinjengeentlobo zefayili kunye ne-pulverulent. Iimpawu zayo zokumelana nokushisa kunye nobunzima be-mastic zifumana ngenxa yokuxutywa kweoli phezu komhlaba.

Ukubunjwa kwesi sixhobo kubandakanya oku kulandelayo:

• IRubber;
• Petroleum bitumen;
• Iisombululo;
• Iifayile;
• Iiplastiki.

I-mastic ye-bhitumen ibintic isebenza ukuba ihlukanise izakhiwo ezingaphantsi komhlaba nakubunzulu ukusuka kwintsimbi, izakhiwo, iipayipi. Ngokuqhelekileyo kusetyenziselwa ukulungiswa kwamagumbi okuhlambela, i-loggias, xa kwakhiwa izakhiwo zamatye, amachibi okubhukuda. I-bittic insumination ekhuselayo ikhusela ekubonakaleni kwe-corrosion. Le nkunkuma ayinayo i-solvents ne-toluene.

Ukwahlula

Izinto eziphathekayo zinokubonakala ziinkalo ezahlukeneyo. Ukunikezelwa kohlobo lwezinto zokuxhuma, kukho i-bituminous, i-rubum-rubber, i-bitumen-
Polymeric. Ngokuxhomekeka kwindlela yokusetyenziswa, ukushisa okutshisa, okubandayo, okufudumeleyo okuphambili okungafuneki ukufudumeza, kodwa ngokushisa okujikelezayo kwama-degrees angaphezu kwe-5, ahlukeneyo.
Into eqhelekileyo iyabaluhluka ngenjongo. I-bittic ibhitumen ye-rubtic esetyenziselwa iinjongo ezahlukeneyo: ukufaka i-insulating, i-gluing, i-asphalt, i-anti-corrosion.

Isicelo

Ukuba ubeka iinjongo kumatshini wokuqhafaza okuza kusetyenziselwa ukukhutshwa kwamanzi okanye ukunyuka kwiindawo zokupakisha ezihlukeneyo, ke kungcono ukusebenzisa ama-mastic ad adhesive. Kodwa kukho imiba emalunga nokupakisha izinto ezibonakalayo. Ngokomzekelo, i-gluing rolls ye-pergamene okanye i-mastic ye-rubber-bituminous mastic ifanelekile. Ukuba uphahla uphahla alukho izinto ezizinzileyo, sebenzisa i-tar pit pitch.

Kwimeko apho kuyimfuneko ukudala ukukhutshwa kwamanzi okanye ukuphawula kwamanzi okanye uhlobo oluthile lwezinto eziphathekayo ekuveliseni iibhodi kuyafuneka, kuyilungele ukusebenzisa i-mastic ekhuselayo.

Ngezinto ezinzulu (umzekelo, izakhiwo ze-hydraulic) okanye ukuthulula amanxeba okukhusela amanzi, sebenzisa iindidi ezinobuninzi bebhitumini. Yenziwe kwi-bitumen efanayo kunye nokudibaniswa kwe-mineral filler. Ezi zingcola zingaba kwi-30 ukuya ku-64% (kuxhomekeke kwiimfuno kunye neemeko).

Sebenza ngezinto eziphathekayo

I-mastic yebhanki yerubha isetyenziswe ngendlela echanekileyo kwiindawo eziliqela. Isiphumo sisisigidi sama-millimitha ezili-10. Ngaphezu kweyure enye kwinkqubo yokubamba. Ungasebenzisa kunye nesicelo esibhaliweyo ngebhashi okanye imivimbo, ukuba kukho isidingo esinjalo. Ukuba kwiiyure ezingama-48 ukushisa okumnandi kuya kuhlala kuma-degrees angama-20, ngoko ngeli xesha, ukuphelisa kuza kuphelisa. Ukuba iqondo lokushisa lingaphantsi kwama-degrees ama-15, ke ukusebenza ngelo bakala akunakunqweneleka kakhulu. Kwindawo efihliweyo kuyimfuneko ukuqinisekisa ukujikeleza okuqhelekileyo. Kubalulekile ukugcina ubuchule bokukhusela, kuba i-mastics efudumele idinga ukufudumala ukuya kwii-180 degrees.
