Isu tinokunda mukuunza-mhando yepamusoro OEM uye ODMmhinduro kune vatinoshanda navo,

inogoneswa ne-tekinoroji yepamusoro uye nehunyanzvi hwekugadzira.

Izvo hazvidi pa-kusanganiswa kwesaiti uye zvinopora kuita rabha yakanyungudika-yakasimba nekusveta mwando mumhepo. Mapoka eurethane muchimiro chayo chemolecular anoisa zvinhu zvacho nekunamira kwakanyanya, kusamira kwemamiriro ekunze, uye deformation simba, zvichiita kuti igadzire chivhariso chekuchinjika pamajoini akavharwa anosanganisa kusapinda kwemvura, kusapinda mhepo, uye kuvharidzira mabasa, anokodzera akasiyana substrates uye nharaunda dzakaomarara. Inofanira kunge isina mvura uye isingapindiki. Mushure mekurapa, inofanira kuumba inoenderera, isiri-lastomer ine porous ine mwero wekutora mvura uri pasi pe0.1%. Panguva yekushandiswa, inogona kumira kumanikidzwa kwemvura kwe0.5MPa uye 10-gore remvura seepage rate isingasviki 0.2L/min. Kuti tigadzirise kushandisa mumakemikari media, tinoda kuti chikamu chimwe che polyurethane sealant chisamirire kunaya kweasidhi, kupfapfaidza munyu uye kuparara kwemafuta, nehuwandu hwekurasikirwa kwehuwandu hwepagore husingasviki 0.5%. Inogona kushandiswa zvakadzikama mu dilute acids uye alkalis uye munyu, asi haidziviriri kune concentrated acids uye alkalis. Ichi chinhu chinoda kutariswa.

Mabhenefiti ekuita kwechikamu chimwe che polyurethane sealant anoona nzvimbo dzayo dzekushandisa. Kubva pazvimiro zvemuviri kusvika kune nyore kushandisa, ndicho chikonzero chekushandiswa kwayo kwakapararira:

Tensile simba: Yakakura kupfuura kana yakaenzana ne2.5MPa;
Elongation panguva yekuzorora: 450% -600%;
Kuramba kwemamiriro ekunze: 85℃/ 95% RH maawa 1000;
Kurapa nguva: 24-72 maawa (25 degree);

Kunaka kwe Imwe-Component Design

Inogona kuburitswa pakuvaka pachishandiswa pfuti yeglue, zvichibvisa kukosha kwekusanganisa-zvinhu zvemukati, kuderedza kukanganisa kwemaoko, uye kunatsiridza basa rekuvaka (mushandi mumwechete anogona kugadzira 30-50 metres yemajoini pazuva).

Wide Adhesion

Inogona kusungirirwa zvakasimba kune ma substrates akadai sesimbi, girazi, kongiri, dombo, uye plastiki pasina kudiwa kweprimer, ine simba rekunamatira reGreater than kana yakaenzana ne1.5MPa.

Fomu Plasticity

Mushure mekuvaka, inogona kuchekwa nemaoko kuita arc yakatsetseka kana kuti yakadzikama, kuyera kuita chisimbiso uye aesthetics.

Chimwe chikamu che polyurethane sealants chinonyanya kushandiswa mumapurojekiti ekuvaka, kuvhara machira emadziro emaketeni uye matenga ekudzivirira mvura. Mumapurojekiti ekufambisa, anogona zvakare kushandiswa kurapa majoini ekuwedzera mabhiriji uye kuronda majoini ekukanganisa? Mukuita, chikamu chimwe che polyurethane chinosimbisa chikumbiro chinokanganiswa ne substrate, ambient tembiricha uye humidity, uye maitiro ekuvaka. Panguva yekushandiswa, nzvimbo yacho inofanira kuchengetwa yakaoma kuitira kunamatira zvakakwana.

Kuti uwane zvirinani kuvhara mhedzisiro, zvakakosha kuomerera kune yakajairwa maitiro kana uchishandisa imwe chikamu polyurethane sealant. Izvi zvinonyanya kuve nechokwadi chekubatana kwakasimba pakati peiyo adhesive layer uye substrate uye yunifomu yekurapa, nekudaro kuwana yakanaka yekudzivirira mvura.

Kugadzirira

Tarisa ambient humidity. Kuporeswa kwechimwe chikamu polyurethane sealant kunoenderana nehunyoro hwemhepo, hunokanganisa kukurumidza kurapa uye kunaka. Humidity range ye50% -80% ndiyo yakakwana.

Sanding

Kunyanya paunenge uchigadzirisa seams ekare, bvisa chero chisimbiso chekare uye wobva waisa jecha pasi pe substrate kuti uderedze iyo oxide firimu uye yekuburitsa mumiririri.

Kuchenesa

Pukuta chero guruva kubva pamusoro nemucheka, wozoipukuta kakawanda nemucheka wakanyikwa mu ethanol 2-3 nguva kubvisa mavara emafuta uye zvigunwe.

Kuomesa

Mushure mekuchenesa, bvumira substrate kuti iome kweinenge maminetsi makumi matatu, kuve nechokwadi kuti hunyoro hwepamusoro huri Pasi kana kuenzana ne8%.

Kushandisa sealant

Isa chisimbiso mupfuti, sundidzira pfuti plunger kuti usvinire kunze zvishoma zvishoma sealant, dzinga chero mweya kubva papombi, uye fambisa pfuti nekumhanya kwakadzikama, kuchengetedza simba rakadzikama kuti uone kuti sealant inozadza gap nguva dzose uye zvizere, pasina mapeji kana voids.

Kuveza sealant layer

Nepo imwe chikamu che polyurethane sealant ichiri kunyorova, igadzirise kudzivirira ganda risingagone kugadziriswa.
