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

inogoneswa ne-tekinoroji yepamusoro uye nehunyanzvi hwekugadzira.

Inowanikwa nename, mvura kana furo, haidi kusanganiswa-pasaiti. Iyo inopedzisa kurapa maitiro nekubata hunyoro mumhepo (kana anoshingaira mapoka ari pamusoro pe substrates), achigadzira yakasimba chigadzirwa chine elasticity, kuoma kana kunamatira. Chimiro chayo chemorethane chine mapoka eurethane (-NHCOO-), ayo anopa zvinhu zvakanaka zvemuchina, kusamira kwemamiriro ekunze uye kunamira, zvichiita kuti zvishandiswe zvakanyanya munzvimbo dzakaita sekuisa chisimbiso, kubatanidza, kudzivirira mvura uye kupupa furo. kuzvirapa{{9}muchina wekuzvirapa une basa rakakosha mukuvaka. Munguva yekushandiswa, inogona kurapa zvakananga nerubatsiro rwekunze kwezvakatipoteredza zvinhu, senge unyoro uye kupisa, zvinobudirira kuderedza mutengo wekuvaka uye kugadzira polymer zvinhu zvine elasticity, kunamatira, uye kusimba.

Chimwe-chikamu chepolyurethane, chine hunhu hwe"kugadzirira--kushandisa, kushanda kwakavimbika uye mashandisirwo akafaranuka", chave chigadzikiso chine hunyanzvi chekutsiva zvinhu zvechinyakare (zvakadai serabha, asphalt, zvinonyungudutsa{{3}zvinonamira) mukugadzira maindasitiri nekuvaka huinjiniya. Kunyanya sekudikanwa kwekuita basa rekuvaka uye kuchengetedzwa kwezvakatipoteredza kuwedzera, chiyero chekushandiswa kwayo chinoramba chichiwedzera.

Imwe-chikamu chepolyurethane sealant chinotipa zvatisingatarisirike kwete kubva pachimiro chayo kuenda kune zvayakanakira uye zvakanakira mukushandiswa.

Form

Namatidza, kurapa mu elastomer pakamuri tembiricha;

Properties

Yakakwirira elasticity (elongation panguva yekuzorora 300% -600%), kusagadzikana kwemvura uye kusagadzikana kwemamiriro ekunze, yakakodzera kuvhara majoini ekuvaka uye zvikamu zvemotokari;

Zvakanakira

Kwete pa-saiti proportioning inodiwa panguva yekuvaka, yakagadzirira kushandiswa mushure meextrusion, uye inokwanisa kuchinjika kune substrate displacement mushure mekurapa.

Curing Conditions

Nguva yekuomeswa kwepamusoro 20-60 maminetsi, kurapa kwakazara kunotora 24-72 maawa.

Kuitwa kwezvakatipoteredza

Chimwe-chikamu chepolyurethane chine mashandiro akanaka ezvakatipoteredza, chinosangana nezvinodiwa zveGB/T 13477-2020 standard, chine VOC inodzika pasi pe50g/L, haine benzene solvents, tar uye heavy metal additives, uye chinogona kushandiswa kwenguva yakareba.

Kuti ushandise imwe-chikamu che polyurethane nemazvo, zvakakosha kuti unzwisise maitiro ayo. Pazasi pane tsananguro yakadzama yemabatiro aanoita kuburikidza ne "moisture therapy":

Kurapa kwepamusoro

Mushure me extrusion, chisimbiso chepamusoro chepamusoro chinotanga kusangana neH₂O mumhepo, ichigadzira urea zvisungo uye kuburitsa CO₂, ichigadzira elastic pamusoro pefirimu. Izvi zvinowanzotora maawa 0-24.

Kurapa kwemukati

Nekufamba kwenguva, mwando unopinda paadhesive layer uye unoramba uchipindirana ne-NCO bonds zvakadzika mukati. Simba uye elasticity zvishoma nezvishoma zvinosvika kune zvakagadzirirwa maitiro. Iyi nzira yakareba, kazhinji inotora mazuva 1-7.

Kurapa kwakakwana

Izvi zvinoreva kuti chinonamira chakachinjika-chakabatana nechomukati nekunze, zvichikonzera kugadzikana kwekushanda.

Pakuchengeta chimwe{{0}chikamu chepolyurethane, zvakakosha kuchengetedza tembiricha iri pakati pe5-30 madhigirii uye kudzivirira chiedza chezuva, tembiricha yepamusoro, uye mwando. Paunosarudza imwe-chikamu polyurethane, funga nezve substrate. Sarudzo dzekubatanidza dzakakodzera dzinosanganisira simbi, kongiri, plastiki, uye zvekunze kunyorera. Nekushandisa kunze, funga nezvemamiriro ekunze uye kutorwa kweUV. Sarudzo yakanakisa ndiyo inokodzera zvakatipoteredza.
