Muzochitika monga kutumiza makina, kusamalira zida zojambulira zithunzi, ndi kusintha kwa malo osungiramo zinthu, ma casters samangofunika kunyamula kulemera kokha, komanso amafunikanso kuganizira za kukana kuwonongeka, bata, kuyenda kokhazikika, ndi moyo wautumiki. Chifukwa chachikulu chomwe ma casters a polyurethane osalunjika amagwiritsidwa ntchito kwambiri ndichakuti amaphatikiza katundu wazinthu ndi kapangidwe kake moyenera. Mwachidule, zimatha kupangitsa kuti chipangizocho chiziyenda bwino komanso kuti chizigwira ntchito bwino m'malo ovuta ambiri.
1. Zinthu zogwiritsidwa ntchito moyenera, kulinganiza kukana kukalamba, kuchepetsa phokoso, komanso mphamvu yonyamula katundu
Polyurethane, yomwe imadziwikanso kuti PU, ndi chinthu chogwiritsidwa ntchito kwambiri monga polima. Ubwino wake uli mu kuchuluka kwa magwiridwe antchito osinthika, omwe amatha kufewa kuti awonjezere mphamvu zotetezera ndi kuchepetsa phokoso, kapena ovuta kuwonjezera kukana kuwonongeka ndi mphamvu zonyamula katundu.
Poyerekeza ndi rabala wamba, polyurethane ndi yolimba kwambiri ndipo siitha kutha msanga chifukwa chogubuduzika kwa nthawi yayitali; Poyerekeza ndi mawilo a nayiloni, imakhala ndi kusinthasintha kwabwino, imakhudza pang'ono pansi ikasuntha, komanso phokoso lochepa. Chifukwa cha izi, ma polyurethane casters nthawi zambiri amagwiritsidwa ntchito m'malo ogwirira ntchito omwe amafunikira chitetezo cha pansi komanso kuwongolera phokoso.
Kapangidwe kake, mtundu uwu wa caster nthawi zambiri umagwiritsa ntchito pakati pa gudumu lachitsulo pamodzi ndi wosanjikiza wa polyurethane. Pakati pa gudumu lachitsulo ndi pomwe pali mphamvu yothandizira, pomwe gawo lakunja la polyurethane limakhudza nthaka mwachindunji ndipo limayang'anira kuyamwa kwa kugunda, kuchepetsa phokoso, komanso kukana kuwonongeka. Pambuyo pa kuphatikiza zonsezi, mphamvu yonse yonyamula katundu ndi kukhazikika kwa ma caster kudzakhala bwino.
2. Mphamvu yabwino yochepetsera phokoso, yoyenera malo okhala ndi zofunikira kwambiri zachilengedwe
Ubwino umodzi waukulu wa ma casters a polyurethane osalunjika bwino ndi phokoso lochepa panthawi yogwira ntchito. Chifukwa chake sichovuta: polyurethane yokha ili ndi kusinthasintha kwina, komwe kumatha kuyamwa mphamvu zina kuchokera pansi pamene mawilo akugubuduzika, zomwe zimachepetsa kugwedezeka ndi phokoso lochitika chifukwa cha kugundana kwamphamvu.
Pa mawilo olimba wamba, mipata yochepa kapena kusalingana pansi kungayambitse phokoso looneka bwino poyenda; Mawilo a polyurethane, chifukwa cha kukhudzana kwawo kofewa komanso kuyenda kosalala, nthawi zambiri amatulutsa phokoso lochepa pansi pa katundu womwewo.
Mtundu uwu wa chinthu ndi woyenera kwambiri m'malo omwe amafunika bata, monga kugwiritsa ntchito zida zojambulira zithunzi, kuyendetsa zida zoyesera, kutumiza makina mkati, ndi malo ena opangira omwe amafunikira malo ogwirira ntchito. Chipangizochi chimakhala chete kwambiri chikayenda ndipo chimathandizanso kuchepetsa kugwedezeka kwa chipangizocho.
3. Kapangidwe ka njira kamapangitsa kuti kuyenda kwa mzere wowongoka kukhale kokhazikika
Kuwonjezera pa ubwino wa zinthuzo, kapangidwe kake kolunjika ndi chinthu chofunikira kwambiri pa mtundu uwu wa caster. Gudumu lotchedwa lolunjika limatanthauza gudumu lomwe limangopita patsogolo molunjika ndipo silingazungulire momasuka ngati gudumu lapadziko lonse.
Ubwino wa kapangidwe kameneka ndikuti kamayenda mokhazikika pamzere wowongoka, makamaka koyenera zochitika monga mayendedwe okhazikika, kukankhira zida kutsogolo ndi kumbuyo, komanso kuyenda kwa zida zopangira. Chipangizochi sichimasinthasintha kwambiri panthawi yoyenda ndipo chimakhala chosavuta kuchilamulira chikagwira ntchito.
Ngati malo ogwiritsira ntchito akuphatikizapo kuyenda m'njira yokonzedweratu, monga mizere yonyamulira katundu, njira zotumizira zida zolemera, kunyamula zithunzi pogwiritsa ntchito njira yolunjika, ma casters olunjika nthawi zambiri amakhala oyenera kuposa ma casters ozungulira. Ngakhale kuti kusinthasintha kwake sikuli kwakukulu ngati kwa mawilo onse, kuli ndi ubwino wambiri pakukhazikika ndi kuwongolera komwe kumayang'anira.
4. Kukana kutentha kwambiri, kukana hydrolysis, kukana mafuta, komanso kusinthasintha kwamphamvu kwa chilengedwe
Zofunikira pa ma casters m'mafakitale nthawi zambiri sizimangophatikizapo kuyenda kokha, komanso kusinthasintha ku malo ovuta. Ma casters a polyurethane olunjika chete alinso ndi ubwino waukulu pankhaniyi.
Choyamba, imakhala yolimba kwambiri ndipo siimatha kusweka kapena kusweka mwachangu ikagwiritsidwa ntchito kwa nthawi yayitali. Kachiwiri, imatha kusinthasintha bwino ndi malo okhala ndi chinyezi, malo okhala ndi hydrolysis, komanso malo ena oipitsa mafuta, zomwe zimapangitsa kuti ikhale yofala kwambiri m'malo operekera mafuta, m'malo osungiramo zinthu, m'ma workshop, ndi m'malo ena.
Zipangizo za polyurethane zosinthidwa pang'ono zimakhalanso ndi kukana kutentha bwino ndipo zimatha kusintha kuti zigwirizane ndi malo ogwirira ntchito mkati mwa kutentha kwina. Izi ndizothandiza kwambiri pa malo ena ochitira masewera olimbitsa thupi otentha kwambiri kapena zochitika zogwiritsira ntchito zomwe zimakhudzidwa ndi kutentha kwakanthawi kochepa.
5. Mukasankha, yang'anani kwambiri pa magawo atatu awa
Yang'anani mphamvu yonyamulira. Posankha mawilo, sikokwanira kungoyang'ana mawonekedwe ndi kukula kwa mawilo, koma chofunika kwambiri, kuwona ngati katundu wovomerezeka wa gudumu limodzi ungakwaniritse zofunikira zonse za kulemera kwa zidazo. Nthawi zambiri amalimbikitsidwa kusiya malire ena kutengera kulemera kwenikweni, komwe ndi kotetezeka komanso kolimba.
Kachiwiri, yang'anani kukula kwa gudumu ndi makulidwe a pamwamba pa gudumu. Kukula kwa gudumu kukakhala kwakukulu, kumakhala kosavuta kukankhira ndipo kumakhala kosavuta kupitirira; Koma ngati malo oyikapo ndi ochepa, payenera kukhala kulinganiza pakati pa kukula ndi zofunikira pakugwiritsa ntchito.
Chachitatu, yang'anani kuuma kwake. Kuuma kwake kwakukulu, nthawi zambiri kumakhala kolimba komanso kolimba; Kuuma kwake kochepa kumabweretsa zotsatira zabwino zoteteza komanso kuchepetsa phokoso. Ngati nthaka si yathyathyathya mokwanira, njira ya polyurethane yokhala ndi kusinthasintha kwabwino ikhoza kuyikidwa patsogolo.
6. Kodi ubwino wake ndi wotani poyerekeza ndi wa anthu wamba oponya miyala?
Poyerekeza ndi mawilo wamba a rabara, mawilo a polyurethane nthawi zambiri amakhala ndi mphamvu yolimba komanso nthawi yayitali yogwira ntchito. Poyerekeza ndi mawilo a nayiloni, amagwira ntchito bwino kwambiri pankhani yochepetsa phokoso, kuyamwa kwa kugunda kwa mtima, komanso kuteteza nthaka.
Kuphatikiza apo, kusiyana pakati pa ma caster otsogolera ndi ma caster olamulira kuyeneranso kudziwika. Mawilo a Universal ndi osinthasintha komanso oyenera zochitika zomwe zimafuna kuzunguliridwa pafupipafupi; Mawilo otsogolera ndi oyenera kwambiri pazochitika zomwe mizere yowongoka, kukhazikika, ndi kuwongolera njira ndizofunikira. Pa ntchito zambiri zonyamula ndi kusamalira zida zamafakitale, ma caster otsogolera ndi othandiza kwambiri.
Mapeto
Ponseponse, ubwino waukadaulo wa ma polyurethane silent directional casters umaonekera makamaka m'mbali zinayi: zinthu zomwe zili bwino, ntchito yopanda phokoso, kuyenda kokhazikika kwa mzere, komanso kusinthasintha kwamphamvu kwa chilengedwe. Pazida zomwe zimafunika kulinganiza bwino zonyamula katundu, zosawonongeka, zosasunthika, komanso zowongolera, ndi chisankho chothandiza.
Pogula zinthu zenizeni, tikulimbikitsidwa kusankha zida kutengera kulemera kwake, momwe nthaka ilili, njira yoyendetsera zinthu, komanso kuchuluka kwa momwe zimagwiritsidwira ntchito. Kusankha mawilo oyenera sikungowonjezera kuyendetsa bwino kwa zida, komanso kuchepetsa ndalama zokonzera ndi kusintha zinthu mtsogolo.
