Nekutsigirwa nekusimudzirwa kwezvivakwa zvakagadzirwa kare pasi rose, indasitiri yekuvaka yapinda zvishoma nezvishoma munguva yemaindasitiri, saka chii chaizvo chinonzi chivakwa chakagadzirwa kare? Zvichitaurwa zviri nyore, zvivakwa zvakagadzirwa kare zvakafanana nemabhuroko ekuvaka. Zvikamu zvekongiri zvinoshandiswa muchivako zvinogadzirwa kare mufekitori pachine nguva, uye zvozoendeswa kunzvimbo yekuvaka kuti zvikwidzwe, zvibatanidzwe uye zviunganidzwe kuti zvigadzire chivakwa.
Chii chiri hukama huripo pakati pezvivakwa zvakagadzirwa kare neMS sealant?
Nekuti zvivakwa zvakagadzirwa kare zvinounganidzwa kubva kuzvinhu zvakagadzirwa kare zvefekitori, pane mipata yekubatanidza pakati pezvikamu. Kuzadza mipata iyi yekubatanidza kwakakosha zvikuru. Parizvino, kune mhando nhatu dzezvivhariso zvekuvaka zvinoshanda zvakanyanya pamusika: silicone, Polyurethane nepolysulfide, MS sealant yakasiyana nechero ipi yeiyi mitatu sealants. Isilicone-modified polyether sealant inogara nhaka hunhu hwe terminal silyl structure uye main chain polyether bond structure, iyo inosanganisa zvakanakira polyurethane sealant nesilicone sealant maererano nekushanda, inzira yakakosha yekuvandudza zvivhariso zvitsva kumba nekune dzimwe nyika.
Saka ndedzipi zvakanakira zveMS sealant zvichienzaniswa nezvisungo zvekuvaka zvakagadzirwa kare?
1.Mwero wepamusoro wekupora wakasununguka uye kugona kwakasimba kwekutama
Nekuti majoini e concrete slabs achakura, kupwanyika, kushanduka uye kuchinjika nekuda kwekuchinja kwetembiricha, kudzikira kwe concrete, kudedera kudiki kana kugadzikana kwechivako, nezvimwewo, kuitira kudzivirira sealant kuti isatsemuke uye kuve nechokwadi chekuti majoini akabatana uye akavimbika, sealant inoshandiswa inofanira kunge ine mwero wakati wekusimba uye inogona kukura nekudzikama nekuchinjika kwekuvhura nekuvharika kwejoin kuti irambe ichivharika. Kugona kwe displacement kwe sealant kunofanirwa kunge kwakakura kupfuura displacement ye board seam. Haizobvaruke uye inogara kwenguva refu panguva ye recyclic deformation. Kana yaboorwa, inogona kuchengetedza nekudzoreredza mashandiro ayo ekutanga uye chimiro. Mushure mekuyedza, elastic recovery rate, displacement capacity uye tensile modulus ye MS sealant zvese zvakapfuura zvinodiwa zvenyika, uye ine hunhu hwakanaka hwemakanika.
2. Kudzivirira mamiriro ekunze kwakanaka
MuJCJ1-2014 "Mitemo yeUnyanzvi yeZvivako zveKonkriti Zvakagadzirwa Nekare", zvinotaurwa zvakajeka kuti zvinhu zvekuvhara zvakasarudzwa zvekubatanidza kuvaka hazvingofanire kungosangana nezvinodiwa zvekushanda kwemakanika kunze kwekugona kwekudzivirira kuchekwa uye kuwedzera uye kugadzikana kwekudzikira kwesimbi, asiwo kusangana nekuoma, kusapinda mvura, zvinodiwa zvekushanda kwekuvaka zvakaita sekuramba kwemamiriro ekunze. Kana zvinhu zvisina kusarudzwa nemazvo, chivharo chichatsemuka, chokundikana kuwana simba rekuvhara, uye kunyange chivharo chichakundikana, izvo zvinokanganisa kuchengetedzeka kwechivako. Maumbirwo echivharo cheMS ipolyether secheni huru, uye inewo mapoka esilyl ane mapoka anoshanda. Inopa mukana wakazara kune zvakanakira zve polyurethane sealant uye silicone sealant, uye inovandudza zvikuru kuramba kwemamiriro ekunze kwechivharo.
3. Kupenda kwakasimba, kuchengetedzwa kwezvakatipoteredza uye kusasvibiswa
Nekuti MS glue ine zvakanakira zvepolyurethane sealant uye silicone sealant, inogadzirisa zvikanganiso zvepolysulfide sealant zvakaita sekunonoka kupora kwekupisa kwakaderera, kukwegura nyore uye kuoma, kushaya simba, uye kunhuhwirira kwakasimba; panguva imwe chete, MS glue haifariri silicone sealants, glue iyi inowanzo buritsa leachate ine mafuta inosvibisa kongiri, matombo nezvimwe zvinhu zvekushongedza. Inokwanisa kupendwa zvakanaka uye inodzivirira nharaunda, izvo zvinosimudzira kukura nekufambira mberi kwezvinovhara zvekuvaka zvakagadzirwa kare.
Kazhinji, zvivakwa zvakagadzirwa kare ndizvo zvinonyanya kukurudzirwa pakugadzirwa kwezvivakwa. Muhurongwa hwese hwekuvaka hwakagadzirwa kare, sarudzo yechisimbiso ichave imwe yenzvimbo huru dzinokanganisa kuchengetedzeka kwechivako chose chakagadzirwa kare. Chisimbiso chechisimbiso chepolyether chakagadziriswa nesilicone——MS sealant ine mashandiro akanaka kwazvo uye ichave sarudzo yako yakanakisa.
SIWAY yakazvipira kupa vatengi zvinhu zvakagadziriswa zvemhando yepamusoro uye zvakavimbika uye mabasa ehunyanzvi akagadzirwa nemaoko. Tekinoroji yeSIWAY yekugadzirisa silane inoramba ichipa mhinduro dzehunyanzvi dzekusunga nekubatanidza zvivakwa zvakagadzirwa kare. Tinotarisira kushanda nemi. Pamwe chete, tichabatsira mukusimudzira zvivakwa zvakagadzirwa kare pasi rose.
