Zophahla yemastic: Iintlobo nemisebenzi

Xa isakhiwo kwesakhiwo, kungakhathaliseki uhlobo nophahla nophahla izakhiwo, ezinye iintlobo zomsebenzi eqhelekileyo. Le ukusebenza kwenkqubo truss, ukufakelwa lathing, ebeka "pie", nto leyo ibandakanya kwiiseli ezininzi, ezifana ukugcina ubushushu, amanzi kunye nangaphezulu. Kusenokwenzeka ukuba kuqatshelwe ukuba kufuneka ukuba umgangatho womsebenzi ukukhetha izinto elungileyo. Ngoko ke, ngokuba ezisongwayo ezisetyenziswa nophahla yemastic, nto leyo eye iintlobo ezahlukeneyo ezikhoyo. Cinga isicelo emaXhoseni kule nto.

Types of zingangenwa

NgeNgca imastic i Umatshini ezimbaxa zomgquba kunye lokufaka, njengoko leyo kusetyenziswa izinto ezifana asbestos, uboya eweni, SLAG, dust, talc kunye nabanye. Ezi kwezithako ngcono iimpawu zobugcisa umbandela (ukwandisa amandla, ukumelana noxinzelelo thermal, kunciphise brittleness kwi abandayo et al.). Ukongeza, zemastic wongezelela kwisigcinakaliso kunye imichiza, ukuthintela ukwenzeka kwingxelo fungal, ulele kunye nezinye negadi.

Ngokuxhomekeka kuhlobo mastics into ephilayo ezilandelayo iintlobo:

• yebhitumene;
• ungalibali;
• ezidibeneyo (bituminous, bituminous-Polymer kunye nabanye);
• lyu.

Kwakhona, oku kungenziwa kalukhuni lahlulwe kuxhomekeke indlela esisetyenziswe Iintlobo ezifana:

• NgeNgca imastic hot - olu hlobo kwezixhobo Umatshini zisetyenziswa zikwimeko eshushu ukwenza beqwalasele izinto nophahla, izinto Tolev kunye nezinye Coatings. Ngaphandle ukusebenzisa umaleko zokuzikhusela zabasebenzi izakhiwo uphahla. Njengomgaqo, olu hlobo ukuba zingangenwa uphahla uchongwe IBC-D - **, apho amanani iindleko kwindawo * kuba uxhathiso ubushushu. Kuxhomekeka ngingqi elimi kunye kwithambeka uphahla lisetyenziswa sealant kunye ukuxhathisa ethile ubushushu. Umzekelo, kuba ngama angasentla isakhiwo kunye isithambeka engaphantsi kwe-2.5% ikhuthaza ukusetyenziswa MBK-T-55.
• kubanda yemastic - eli izinto ekrwada esetyenziselwa ngokulitywina uqhubekeko iindawo yaxokomezela sheets daka, xa ebeka web eziyinzuzo zokuxhasa uphahla umsebenzi wokulungisa. Xa usebenzisa olu hlobo yemastic exutywe kunye izinyibilikisi (ngomoya uyat), ipetroli, izinyibilikisi kunye nabanye.

Ukusetyenziswa a zingangenwa ukuba uphahla

Imiqathango neendlela ukusetyenziswa kwale nto inokuba ezahlukeneyo, kodwa kusenokwenzeka ukuba ezinye iingongoma eziqhelekileyo kuzo zonke iintlobo yemastic:

• Cool uphahla wemastic isetyenziswe kunye spatula, yaye xa usebenzisa ibrashi okanye ngokusebenzisa indlela beleni oko kuyimfuneko ukuze yaze yangxenga ifuthe lomanyano, kwinqanaba avumelekile - hayi ngaphezulu kwe-30% kuphela.
• Zemastic engamanzi kufuneka isetyenziswe tyaba, umphezulu esihlambulukileyo apho precoat kuyimfuneko ukuba asebenzise umaleko kuqala yebhitumene primer.
• Xa umsebenzi kuyimfuneko ukuba balumke, kuba izinto eziqulethe nophahla yemastic, ityhefu. Ngoko ke, ukuba ukuzikhusela yityhefu, kucetyiswa ukuba banxibe izibuko zokuzikhusela, baphefumla (xa isicelo zemastic kushushu), iiglavu kunye neempahla.
• Bituminous uphahla olungiselela ashushu, ngokuqhelekileyo izixhobo ezizodwa kwi-mveliso. ukulungiselela Self kwakhona kunokwenzeka, kodwa kuyimfuneko ukulungiselela isikhongozeli, nto leyo nqgo ingaphakathi yezitena. Kwakhona, isiciko etankini kufuneka ambathe ivaliwe. Iqondo lobushushu ukufudumeza - malunga 180 ° C, isisombululo kufuneka rhoqo ukukhwezela, ubumdaka ezingafunwayo kufuneka zisuswe (ukulungiselela ezi njongo zinokusetyenziswa ngesihlungulo yesinyithi okanye esinye isixhobo esifanayo). yemastic Hot kufuneka ilungiswe iiyure 2-3 phambi kokuba abulawe.

NgeNgca imastic ibonelela uqhagamshelo elide namatywina Ipeyinti ukuba zingangenwa layer ifunyenwe egudileyo, anamandla ixesha elide ngokwaneleyo. Ukusetyenziswa kwale nto inceda ukuthintela imbonakalo izakhiwo imingxunya umonakalo umhlwa, nto leyo eyandisa umgangatho womsebenzi owenziwa.
