Ibisubizo bisanzwe by'ubwubatsi ku igorofa ryo munsi y'ubutaka

Ku bijyanye n'aho imodoka ziparika munsi y'ubutaka, ibisubizo bisanzwe byo hasi birimo: hasi hakozwe mu buryo bwa epoxy, hasi hadasaza neza n'aho hasi hadasaza cyane.

Epoxy hasi: epoxy hasi muri garage

Ibara rya epoxy, ni ukuvuga irangi rya epoxy resin nk'ikintu cy'ingenzi, hamwe n'umucanga wa quartz/ifu nk'ibikoresho by'inyongera, hakoreshejwe gusya, gusukura, gukurura, gukurura cyangwa gutera sima n'ubundi buryo bwo kubaka, kugira ngo haboneke ubuso bw'ubutaka. Nyuma yo kubaka ubutaka, urwego rwa epoxy rutwikira sima y'ibyatsi, bityo bigatandukanya cyane cyane sima y'ibyatsi n'ibibazo bishobora kubaho nk'umucanga, ivumbi n'ibindi. Ubuso bw'ubutaka bwa epoxy, ntibugira ivumbi, ntiburamba, bworoshye gusukura, bufite ibara ryiza.

Ibikoresho bikunze gukoreshwa nk'ibikoresho byo guparika imodoka mu buryo bwa epoxy ni ibi bikurikira: ibikoresho byo gupakira imodoka mu buryo bwa mortier, ibikoresho byo gupakira imyenda mito, ibikoresho byo gupakira imodoka mu buryo bwa epoxy.

Ubusanzwe, ikoreshwa rya epoxy yo mu bwoko bwa mortar, ni: gusya no gusukura substrate, epoxy primer imwe, epoxy mortier imwe cyangwa ebyiri, epoxy putty ebyiri, epoxy surface packaging ebyiri. Ubunini buri hagati ya mm 0.8-1.5.

Ubusanzwe, ikoreshwa rya epoxy yo mu bwoko bwa "coating" rigizwe n'ibi bikurikira: gusya no gusukura substrate, "epoxy primer" imwe, "epoxy mortier" imwe, "epoxy putty" imwe, "epoxy surface coating" imwe. Ubunini buri hagati ya 0.5-0.8mm.

Ubusanzwe, uburyo bwo gusya no gusukura ifu y'ubutaka, epoxy primer imwe, epoxy mortier ebyiri, epoxy putty imwe, epoxy flow plane coating imwe. Ubunini buri hagati ya mm 2-3.

Ubutaka bworoshye bwo mu bwoko bwa epoxy, gusa mu rufatiro rw'ubutaka buragororotse cyane, imbaraga za sima ni nziza cyane, kandi ingengo y'imari ni nto cyane, ingaruka zigaragara z'ibisabwa mu gasanduku ntabwo ari nyinshi, muri rusange ntibisabwa. Ubutaka bwo mu bwoko bwa epoxy bwo mu bwoko bwa mortar, ugereranije n'ubutaka bworoshye bwo mu bwoko bwa epoxy, ubuso burarambuye, bworoshye, burwanya kwangirika, kandi burakomera cyane, ni gahunda yo gusiga ipaki ya epoxy munsi y'ubutaka. Ubutaka bwo mu bwoko bwa epoxy bukoreshwa gusa mu nzego za leta, ahantu imikino Olempike n'indi mishinga y'igihugu yo gusiga ipaki. Byongeye kandi, imishinga y'umuntu ku giti cye, umukoresha mu gihe adakurikirana ubuso bugororotse n'ingaruka z'amatwi, kugira ngo asubize gusa ubuso bwa sima bw'umucanga, ivumbi, hari primer ebyiri za epoxy, epoxy ebyiri zo hejuru za gahunda yoroshye ya epoxy.

Bityo rero, ikintu cy'ingenzi mu guhitamo ubwoko bwa gahunda yo gushyira hasi ya epoxy, icya mbere, ishingiro ry'ubutaka, icya kabiri, ingaruka zikenewe kugira ngo zigerweho, hanyuma ingengo y'imari ikoreshwa. Hagati yabyo bitatu birasobanutse kandi byuzuzanya.

Parike idashira

Ibikoresho byo hasi birwanya ubusakare bishingiye kuri sima, bigizwe na sima yihariye, ifu idapfa ubusakare (umucanga wa quartz, emery, tin-titanium alloy, nibindi) hamwe n'ibindi bikoresho, kugira ngo bigerweho mu buryo bwa siyansi hakoreshejwe uburyo buvanze n'uruganda kugira ngo bikoreshwe mu ishashi.

Kubaka hasi hadashaje bihuzwa no kubaka sima. Nyuma yo gusimbuza sima, kuyitunganya no kuyizunguza ku buso bw'aho imodoka zihagarara munsi y'ubutaka, ibikoresho byo hasi bidashaje bizakwirakwizwa ku buso mu cyiciro cya mbere cyo gukomera, kandi ibikoresho bidashaje bizubakwa byose hamwe na sima ya sima binyuze mu gikoresho cyihariye cyo kubaka hasi, imashini itunganya, kugira ngo habeho urwego rwo kurinda ku buso bwa sima ya sima.

Nkuko twese tubizi, sima nyinshi zikoreshwa munsi y’ubutaka zikoreshwa mu guparika imodoka zikozwe muri sima C20, sima isanzwe ya C25, sima ya C25, urugero, imbaraga zo gukandagira hejuru zingana na 25MPA. Ariko nyuma yo kubaka hasi idashobora kwangirika, imbaraga zo gukandagira hejuru zishobora kugera kuri 80MPA, cyangwa zirenze 100MPA, kandi izindi mbaraga zo gukandagira, imbaraga zo kudakandagira hamwe n’ibindi bimenyetso nabyo byarazamuwe cyane.

Kubera ko hasi idashira ari iy'ibicuruzwa bishingiye kuri sima, bityo ishobora guhuzwa neza na sima, igihe cyose sima yo mu mizi y'ubutaka idacitse, hasi idashira mu myaka ibarirwa muri za mirongo idacika, idashira. Muri icyo gihe, ibara ntabwo ari ryiza kandi rikungahaye nk'iry'ubutaka bwa epoxy, muri rusange riba rifite ibara ry'umukara, icyatsi kibisi, umutuku n'andi mabara y'ibanze.

Sima isanzwe ya sima, bitewe n'umusaruro n'ubwubatsi budakwiye, cyangwa ihindagurika ry'ikirere mu myaka yashize, biroroshye guhindura umucanga, ivumbi, ni ukuvuga sima ya sima mu gutandukanya umucanga, amabuye na sima. Ubwo bwoko bw'aho imodoka ziparika, isuku y'ibidukikije biragoye cyane, ubuso bw'imodoka ziparika burimo ivumbi, nyirayo arinubira cyane. Ubutaka budashobora kwangirika ni igisubizo gihendutse kandi gifatika kuri iki kibazo. Ubutaka ntibukigaragara nk'ubusa n'umucanga, kandi bitewe n'uko imodoka isya kandi ikora nabi, ubutaka budashobora kwangirika buzaba bufite ubwiza bungana.

Parikingi isanzwe irinda kwangirika kw'imodoka munsi y'ubutaka, ahanini iy'umucanga wa quartz n'iy'umucanga irinda kwangirika kw'imodoka yo mu bwoko bwa diyama. Ibara rikunze kuba ibara rya sima cyangwa imvi.

hasi hakonjesha

Inzu yo mu igaraje iri ku butaka bwa sima, irinda kwangirika kw'umucanga, iy'ubutaka ya terrazzo, n'ibindi, niba igaraje yasutsweho sima kandi ikaranze, ni byiza gukora neza iy'ubutaka ya Yade, kubaka biroroshye, ibimenyetso bya tekiniki n'iy'ubutaka idashira biragereranywa no kubungabunga nyuma biroroshye cyane, ari nabyo byiza by'inzu yo mu igaraje. Inzu yo mu igaraje iyo intego ya mbere yo guteza imbere iy'ubutaka idashira, ni ugushaka ikindi gisimbura iy'ubutaka ya epoxy, ariko kandi iy'ubutaka idashira ni nziza idashira, iy'ubutaka idashira nyuma yo kubaka ibara ntabwo igera ku butaka bwa epoxy nk'ubufite amabara menshi, ariko itandukaniro si rinini, itandukaniro riri hagati y'ibi byombi riri mu bunini bw'ubutaka bwa epoxy ni ubunini runaka, iyo yubakishijwe ubw'ububi, biroroshye cyane gukuraho uruhu, kandi kuvugurura no kubungabunga bitinze biragoye cyane, kandi uruhare rw'imikorere y'inzu ya Yade. Uburyo bwo gupakira hasi butuma hasi hashyirwa sima, kandi bugakoreshwa na sima, amaherezo bigatuma ubuso buhinduka bufunze, ntabwo bukemura gusa ikibazo cyo gupakira sima no gusiga imvi icyarimwe bishobora no kongera cyane ubukana bw'ubuso bwa sima, kandi icyarimwe ku gisubizo cya aside na alkali bigira uruhare runaka mu kwitandukanya, ba nyir'amazu benshi ku isoko bakoresha hasi hashyirwa sima nk'ubutaka bwa mbere bwa gareji.
