Sezvatinoziva tese, ma polyurethane casters anoumbwa achishandisa polyurethane raw material. Kudira ma polyurethane casters inzira inosanganisira zvakawanda zvinobatanidzwa, kubva pakugadzirira kwekutanga kusvika pakugadziriswa kwekupedzisira nekugadzirisa, danho rega rega rinoda kushanda kwakanyatsojeka uye kudzora kwakasimba. Saka ma polyurethane raber casters anofanira kupfuura nematanho mangani kuti aumbwe?
Kugadzirira nguva isati yasvika
Usati watanga kudira ma polyurethane casters, kugadzirira kwakakwana kunodiwa. Chekutanga, zvinhu zvakakodzera zvakaita se polyurethane resin, catalyst, filler uye solvent zvinofanira kusarudzwa. Zvinhu izvi zvinofanira kunge zvine simba rakanaka remakanika, kusakara uye kuramba ngura. Panguva imwe chete, zvishandiso nemidziyo yakakodzera zvinofanira kugadzirirwa, zvakaita sezviyero, zvinosanganisa, mamold nezvimwewo. Kusarudzwa kwemamold kunofanirwa kuenderana nehukuru nechimiro chemamold, ukuwo kuchivimbisa kusimba uye kugadzikana kwemamold.
Kusanganisa
Sanganisa polyurethane resin yakasarudzwa, catalyst, filler uye solvent zvichienderana nehuwandu hwakati. Munguva yekusanganisa, teerera kudzora tembiricha uye viscosity kuti uve nechokwadi chekuti kuyerera kwezvinhu zvakagadzirwa zvakanaka. Mushure mekusanganisa, dururira polyurethane yakasanganiswa muforoma yakagadzirwa kare.
Kudurura
Munguva yekudurura, kumhanya kwekudurura nekumanikidza kunofanira kudzorwa kudzivirira matambudziko akadai semabubble emhepo uye kushomeka kwezvinhu. Panguva imwe chete, cherechedza kuti utarise mamiriro ekudurura uye gadzirisa kumhanya kwekudurura nekumanikidza nenguva. Kazhinji, macaster ekudurura anofanira kunge akakura zvishoma pane saizi chaiyo inodiwa pakuchekerera mushure mekugayiwa.
Kugadzirisa uye Kugadzirisa
Zvinhu zvepolyurethane zvinoda kugadziriswa uye kugadziriswa mushure mekukandwa. Nguva yekukandwa inowanzova maawa makumi maviri nemana, panguva iyo pamusoro pesuru inofanira kuchengetwa yakanyorova, uye inogona kunyoroveswa kana kudzivirirwa kubva kuzuva, nezvimwewo, zvichienderana nemamiriro ekuvaka. Munguva yekugadzirisa, kungwarira kunofanira kutorwa kudzivirira kukanganiswa kwezvinhu zvekunze pazvigadziko, zvakaita sekupisa nehunyoro.
Hunhu hweKushanda
Kuramba Kusviba: Mapombi epolyurethane akaumbwa ane kusviba kwakanyanya, anogona kushandiswa kwenguva yakareba munzvimbo dzisina kunaka dzekushanda, uye anowedzera hupenyu hwebasa zvakanyanya.
Muchina wakanaka wekugadzira polyurethane unofanira kunge uine zvinhu zvinotevera:
Kudzivirira mafuta: chinhu ichi chinodzivirira ngura zvakanaka kumarudzi akasiyana-siyana emafuta uye chakakodzera nzvimbo dzakasiyana-siyana dzakasvibiswa nemafuta.
Kusapinda mumvura: ma "cast polyurethane casters" haakurumidzi kuchinjika mumvura uye anodzivirira mvura zvakanaka.
Kudzivirira kupisa kwakaderera: chinhu ichi chinogona kuramba chakapfava kana chiri mumamiriro ekunze ekupisa kwakaderera, chakakodzera nzvimbo dzinotonhora.
Kudzivirirwa kwezvakatipoteredza: polyurethane haina chepfu uye haina hwema, izvo zvinozadzisa zvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye zvinobatsira pakukura kwenguva refu.
