Munyika yekuvaka, kukosha kwezvisungo zvekubatana hakufanirwe kutaurwa zvakanyanya. Zvinhu izvi zvinoita basa rakakosha mukuona kuti chimiro chazvo chakasimba uye kugara kwenguva refu uye zvinhu zvakasiyana-siyana zvekuvaka, kunyanya zvisungo zvekongiri. Pakati pemhando dzakasiyana dzezvisungo zvekubatana, zvisungo zvepolyurethane isarudzo yakakurumbira nekuda kwekushanda kwazvo uye kushanduka-shanduka.
Magadzirirwo eUniversal GP Construction Joint PU Adhesive Sealant
SV 811FC chinhu chimwe chete, chemhando yepfuti, chinonamira uye chinovhara uye chinosimba zvachose. Chinhu ichi chine mabasa maviri chakavakirwa pachivharo chepolyurethane chinoporesa hunyoro.
Zvinhu zvirimo
1. Kunamira kwakanaka kwazvo pazvinhu zvese zvakagadzirwa nesimende, zvidhinha, zviumbwa zvedongo, girazi, simbi, huni, epoxy, polyester uye acrylic resin.
2.Kukurumidza kurapwa.
3.Kupisa kwemvura uye kudzivirira mvura.
4.Haiparadzi. Inogona kupendwa nemvura, mafuta, uye pendi dzakagadzirwa nerabha.
(Miedzo yekutanga inokurudzirwa).
5.Kugara kwenguva refu.
6. Inogona kushandiswa mumajoini anodzivirira kutapukirwa
Padanho guru, zvinosunga majoini zvakakosha kudzivirira mvura, mhepo, nezvimwe zvinhu zvezvakatipoteredza kuti zvisapinde mumaburi uye zvinosangana nezvinhu zvekuvaka. Izvi zvakakosha zvikuru kune zvivakwa zvekongiri, sezvo kupinda kwehunyoro kunogona kukonzera ngura yesimbi, kukuvara kwechando-kunyunguduka uye kuora kwekongiri yese. Nekunyatsovhara majoini, zvinosunga majoini zvepolyurethane zvinopa dziviriro inobatsira kuchengetedza kugadzikana kwechivako uye kugara kwenguva refu.
Zvikurukuru, zvakakosha kunzwisisa hunhu hwakasiyana hwema "polyurethane joint sealants" anoita kuti zvive zvakanaka pakubatanidza kongiri. Kusiyana nema "sealants" echinyakare, ma "polyurethane sealants" anochinjika zvakanyanya uye anokwanisa kuchinjika nekufamba uye kukura kwezvivakwa zvekongiri. Kuchinjika uku kwakakosha munzvimbo umo kuchinja kwetembiricha nekufamba kwechimiro kunowanzoitika, sezvo kuchidzivirira "sealant" kuti isatsemuke kana kurasikirwa nekushanda kwayo nekufamba kwenguva.
Pamusoro pezvo, ma polyurethane sealants anonamatira zvakanaka pamusoro pekongiri, zvichiita kuti pave nechisungo chakasimba uye chinogara kwenguva refu chinosunga majoini zvinobudirira. Chisungo ichi chakakosha pakuchengetedza kusimba kwesealant pasi pemamiriro akasiyana-siyana ezvakatipoteredza uye kushushikana kwechimiro. Pamusoro pezvo, ma polyurethane sealants anodzivirira zvakanyanya kukanganiswa nemamiriro ekunze, makemikari, uye UV, zvichiita kuti akwanise kushandiswa pakuvaka mukati nekunze.
Mumajoini ekongiri, ma polyurethane sealant ane hunhu hwakanaka mukugadzirisa mafambiro emajoini anochinja-chinja uye asingachinji. Izvi zvinonyanya kubatsira pakushandiswa kwakadai semajoini ekuwedzera, apo sealant inofanira kukwanisa kutsungirira kufamba kwakakosha pasina kukanganisa hunhu hwayo hwekuvhara. Nekushandisa ma polyurethane sealant mumajoini ekongiri, nyanzvi dzekuvaka dzinogona kuona kuti majoini anoramba akavharwa zvakanaka uku dzichipa mukana wekugadzirisa mafambiro echimiro.
Muchidimbu, kushandiswa kwezvivharo zve polyurethane pakuvaka, kunyanya muzvivharo zvekongiri, kwakakosha pakuona kuti zvivakwa zvekuvaka zvinogara kwenguva refu uye zvinoshanda. Zvivharo izvi zvinopa dziviriro yakavimbika kubva kumigumisiro yehunyoro, mhepo, nezvimwe zvinhu zvakatipoteredza ukuwo zvichipindirana nemafambiro anochinja-chinja ari muzvivakwa zvekongiri. Nekunzwisisa kukosha uye hunhu hwakasiyana hwezvivharo zve polyurethane, nyanzvi dzekuvaka dzinogona kuita sarudzo dzakagadzirwa neruzivo dzinowedzera kunaka uye hurefu hwemapurojekiti avo.
