Kupirira Kwaumisiri mu Zoseweretsa Zagalu Zampira Wolemera

Popanga zinthu zomwe zimapangitsa kuti pakhale kupsinjika kwambiri, vuto lalikulu ndikupewa kutopa kwakuthupi. M'dziko lazogulitsa ziweto, heavy duty rabara zidole za galu imagwira ntchito ngati chitsanzo choyambirira chakugwiritsa ntchito kwambiri elastomer. Zoseweretsazi zimakhala ndi "point loading" - kupanikizika kwakukulu, kokhazikika kwa dzino la canine - zomwe zingapangitse mapulasitiki wamba kusweka kapena kung'ambika.

Kugwiritsa ntchito ma elastomers okwera kwambiri kumathetsa izi kudzera pamapangidwe apadera. Chifukwa zidazi zimakhala ndi kulumikizana kwamphamvu pakati pa unyolo wosinthika wa mamolekyulu, mphamvu yochokera pa kuluma imagawidwa pamtundu wonse wa polima m'malo mokhazikika pomwe ikukhudzidwa. "Kusamuka kwamphamvu" uku ndi chizindikiro chaukadaulo wokonzekera bwino kwambiri. Poonetsetsa kuti zinthuzo zimakhala ndi kutentha kwa galasi lotsika, akatswiri amapanga chidole chomwe chimakhala chosinthika komanso chosagwira ntchito mosasamala kanthu za chilengedwe. Kaya chidolecho chimagwiritsidwa ntchito kuseri kwa chisanu kapena paki yotentha ndi dzuwa, mphamvu zake zapamwamba zimakhalabe zokhazikika, zomwe zimalepheretsa kupangika kwa mikwingwirima yakuthwa, yowopsa.

Kuchita Kwamphamvu kwa Zoseweretsa za Agalu a Rubber kwa Aggressive Chewers       

Kwa kagawo kakang'ono ka msika - "wotafuna mphamvu" -kukhazikika kokhazikika sikukwanira. Kugwiritsa ntchito kwambiri elastomers mu zoseweretsa agalu amphira zamatafuna aukali kumafuna kuyang'ana pa "m'badwo wotentha wochepa." Galu akamatafuna mosalekeza, kukangana kwamkati mkati mwa zinthu kumatha kupangitsa kuti matenthedwe achulukane, omwe nthawi zambiri amafewetsa ndi kufooketsa ma elastomer wamba.

Komabe, ma elastomers okwera kwambiri amapangidwira kuti akhale ndi mphamvu zabwino kwambiri. Amasunga mphamvu zawo pa kutentha kwakukulu, kutanthauza kuti kukhulupirika kwa chidole sikumanyozeka panthawi yakutafuna kwambiri. Kukhazikika kwamafuta awa kumatheka kudzera muulamuliro wolondola wazinthu panthawi yokonzekera zinthu. Pogwiritsa ntchito kugawa kwa maselo olemera, opanga amatha kupanga chinthu chomwe chimamveka "chofewa" chokwanira kuti chigwirizane ndi nyama koma ndi molecularly "chovuta" chokwanira kukana puncturing. Kuchulukana kwamphamvu komanso kulimba kwamphamvu kumeneku ndi komwe kumapangitsa zoseweretsa izi kupulumuka miyezi yachipongwe pomwe ena amalephera mphindi imodzi.

Ubwino Wamapangidwe a Zoseweretsa Zampira Wolimba       

Muzinthu zambiri zamafakitale ndi ogula, "kulimba" kwa gawo ndi mphamvu yake yayikulu. Zoseweretsa zagalu zolimba gwiritsani ntchito kachulukidwe ka ma elastomer amphamvu kwambiri kuti mupereke kulemera ndi mayankho omveka omwe zidole zopanda kanthu sizingafanane. Kuchokera pamawonekedwe ogwiritsira ntchito, unyinji wolimba wa zinthu zogwira ntchito kwambiri umakhala ngati chosokoneza chododometsa.

Tekinoloje yokonzekera yomwe imagwiritsidwa ntchito pamitundu yolimbayi imatsimikizira kuti palibe matumba amkati amkati kapena "voids" zomwe zitha kukhala ngati zolephera. Chifukwa zinthuzo zimakumana ndi RoHS 2.0, REACH, ndi mfundo zaulere za PFAS, kachulukidwe kakang'ono ka chidole simabwera pamtengo wachitetezo chamankhwala. Kumanga kolimba kumalola kuphatikizika kwa ma geometries ovuta a pamwamba-monga grooves yakuya kapena nubs zokwezeka-zomwe zimakhalabe zikugwira ntchito pakapita nthawi. Muzochitika zokhuza kwambiri, monga chidole choponyedwa pakhoma la konkire kapena kugwidwa ndi nsagwada zamphamvu, elastomer yolimba imasunga mawonekedwe ake ndi "kubwereranso" chifukwa cha kusungunuka kwakukulu komwe kumapangidwa ndi maselo ake.

Kutsata Zachilengedwe mu Rubber Pet Toys     

Kugwiritsiridwa ntchito kwa zinthu zilizonse m'nyumba kuyenera kuyang'anira chitetezo ndi malamulo a chilengedwe. Zida za elastomer zapamwamba zili patsogolo pa "green" polima chemistry. Popanga zoseweretsa za mphira , ndikofunikira kuti zinthuzo zisawononge mankhwala owopsa.

Potsatira malamulo a PAHs, POPs, TSCA, ndi REACH, ma elastomerwa amapereka njira ina yopanda poizoni ngati PVC yachikhalidwe kapena mphira wothira mankhwala. Izi ndizofunikira makamaka pazinthu zomwe zimapezeka nthawi zambiri mkamwa mwa chiweto. Ukadaulo wokonzekera umalola kupanga zida zapamwamba kwambiri popanda kufunikira kwa plasticizers poizoni kapena heavy metal stabilizers. Chifukwa chake, "mphamvu yayikulu" yazinthuzo imafanana ndi "chitetezo chachikulu," ndikupangitsa kuti ikhale yoyenera pazinthu zomwe zimafunikira kulimba kwakuthupi komanso kusakhazikika kwachilengedwe.

Kukhazikika Kwamafuta ndi Kuthamanga Kwambiri Panja Panja      

Chimodzi mwazinthu zochititsa chidwi kwambiri za ma elastomer amphamvu kwambiri ndi momwe amagwirira ntchito kumadera ovuta kwambiri. Labala wamba nthawi zambiri amakhala wowuma komanso wosasunthika pakazizira, kapena mkamwa ndi kufooka pakatentha. Ma elastomers okwera kwambiri, komabe, amapangidwa kuti azikhala osalala kwambiri pamatenthedwe otsika komanso mphamvu yayikulu pakutentha kwambiri.

Khalidwe ili ndilofunika heavy duty rabara zidole za galu cholinga ntchito panja. M'nyengo yozizira, chidole chopangidwa kuchokera kuzinthu izi sichidzagwedezeka chikagwetsedwa pa nthaka yozizira. Mosiyana ndi zimenezi, kutentha kwa chilimwe, zinthuzo sizidzataya "kujambula" kapena kukhala ofewa moopsa. Kutentha kwakukulu kumeneku kumagwira ntchito chifukwa cha maunyolo osinthika a maselo amatha kuyenda momasuka popanda kutaya ma intermolecular. Izi zimawonetsetsa kuti ntchito ya malondayo ndi yodziwikiratu komanso yotetezeka masiku 365 pachaka, mosasamala kanthu za komwe kuli.

Popanga zinthu zomwe zimapangitsa kuti pakhale kupsinjika kwambiri, vuto lalikulu ndikupewa kutopa kwakuthupi.
