Nerutsigiro rwepasi rose nekusimudzirwa kwezvivakwa zvakagara zvakagadzirirwa, indasitiri yekuvaka yakapinda zvishoma nezvishoma muzera remaindasitiri, saka chii chaizvo chivakwa chakagadzirwa kare?Zvichitaurwa zviri nyore, zvivakwa zvakagara zvakavakwa zvakafanana nematombo ekuvaka.Midziyo yekongiri inoshandiswa muchivako chacho inogadzirwa kare mufekitari pachine nguva mberi, uye ipapo inotakurwa kuenda kunzvimbo yokuvaka nokuda kwokusimudzwa, kubatanidza uye kubatanidza kuumba chivako chacho.
Ndehupi hukama pakati pezvivakwa zvakagadzirirwa uye MS sealant?
Nemhaka yokuti zvivako zvakagara zvagadzirwa zvakaunganidzwa kubva kuzvinhu zvakafanogadzirwa mufekitari, pane zvisingadzivisiki kuti pane mikaha yegungano pakati pezvinoumba.Kuzadza aya mapeji egungano kunonyanya kukosha.Parizvino, kune marudzi matatu emhando yepamusoro-yekuvaka zvisimbiso pamusika: silicone, Polyurethane uye polysulfide, MS sealant yakasiyana nechero ipi yezvisimbiso izvi zvitatu.Iyo silicone-yakagadziridzwa polyether sealant iyo yakarongeka inogara nhaka hunhu hweiyo terminal silyl chimiro uye main chain polyether bond chimiro, iyo inosanganisa zvakanakira polyurethane sealant uye silicone sealant maererano nekuita, igwara rakakosha pakuvandudzwa kwetsva. sealants kumba nekune dzimwe nyika.
Saka ndeapi mabhenefiti eMS sealant kana ichienzaniswa neyechinyakare yakavakirwa chisimbiso chekuvaka?
1.Yakakwira elastic kudzoreredza mwero uye yakasimba yekusimuka kugona
Nekuti majoini ekongiri slabs anozowedzera, kupesana, deformation uye kutamiswa nekuda kwekushanduka kwetembiricha, kongiri shrinkage, zvishoma vibration kana kugadzika kwechivako, nezvimwewo, kuitira kudzivirira chisimbiso kubva pakutsemuka uye kuve nechokwadi chekuchengetedza uye yakavimbika chisungo uye chisimbiso. yemajoini, chisimbiso chinoshandiswa chinofanirwa Iine imwe dhigirii yekunyungudika uye inogona kuwedzera zvakasununguka uye chibvumirano nekuvhurwa nekuvhara deformation yejoini kuchengetedza kuvharirwa kwejoinhi.Kutamisa kugona kwechisimbiso kunofanirwa kunge kwakakura kudarika kuchinjika kweiyo bhodhi seam.Iyo haizobvarura uye yakasimba panguva yakadzokororwa cyclic deformation.Yakaputirwa, inogona kuchengetedza uye kudzoreredza kuita kwayo kwepakutanga uye chimiro.Mushure mekuyedzwa, iyo elastic kudzoreredza mwero, kufambisa simba uye tensile modulus yeMS sealant zvese zvakapfuura zvinodiwa nenyika, uye ine yakanaka michina zvivakwa.
2. Kuramba kwemamiriro ekunze kwakanakisa
MuJCJ1-2014 "Technical Regulations for Prefabricated Concrete Structures", zvinonyatsotaurwa kuti zvinhu zvekuisa chisimbiso zvakasarudzwa pakuvaka majoini hazvizongosangana nezvinodiwa zvemakina kunze kwekunge shear resistance uye kuwedzera uye contraction deformation kugona, asiwo inosangana nekuramba ukuru, kusapinda mvura, Kuvaka muviri kuita zvinodiwa semamiriro ekunze kuramba.Kana iyo chinyorwa chisina kusarudzwa zvakanaka, chisimbiso chinoputika, chinokundikana kuzadzisa chisimbiso, uye kunyange chisimbiso chichakundikana, izvo zvichakanganisa kuchengetedzwa kwechivako.Chimiro cheMS sealant ndeye polyether secheni huru, uye zvakare ine silyl mapoka ane anorapa anoshanda mapoka.Inopa kutamba kwakazara kune zvakanakira polyurethane sealant uye silicone sealant, uye inovandudza zvakanyanya kupikisa kwemamiriro ekunze kwechisimbiso.
3. yakasimba paintability, kuchengetedzwa kwezvakatipoteredza uye kusvibiswa-isina
Nekuti MS glue ine zvakanakira zvese zviri zviviri polyurethane sealant uye silicone sealant, inogadzirisa izvo zvinokanganisa zvepolysulfide sealant senge kunonoka kudzika-tembiricha kurapa kumhanya, kuchembera uye kuoma, kushaya kusimba, uye kunhuhwirira kwakasimba;panguva imwecheteyo, MS glue haifanire silicone sealants, iyo inonamira layer inokwanisa kugadzira mafuta leachate inosvibisa kongiri, dombo uye zvimwe zvekushongedza zvinhu.Iyo ine yakanaka paintability uye kuchengetedzwa kwezvakatipoteredza, izvo zvinowedzera kusimudzira kusimudzira uye kufambira mberi kwezvakagadzirwa zvisimbiso zvekuvaka.
Muzhinji, zvivakwa zvakagadzirirwa ndizvo maitiro ekusimudzira emhando dzekuvaka.Mugadziriro yose yekuvaka yakagadzirwa, kusarudzwa kwechisimbiso kuchava chimwe chezvibatanidza zvakakosha zvinokanganisa kuchengetedzwa kwechivako chose chakagadzirwa.Silicone yakagadziridzwa polyether sealant sealant--MS sealant ine hunyanzvi hwekuita uye ichave sarudzo yako yakanaka.
SIWAY yakazvipira kupa vatengi zvinhu zvakagadzika uye zvakavimbika zvemhando yepamusoro-soro uye masevhisi ehunyanzvi.SIWAY's silane modified tekinoroji inoenderera mberi nekupa zvigadziriso zvehunyanzvi zvekuvharirwa chisimbiso chekuvaka uye kubatana.Tinotarisira kushanda newe.Pamwe chete, tichabatsira kusimudzira kwakasimba kwezvivakwa zvakagara zvakagadzirirwa munyika.
