Sarudza Mutauro 
Paunenge uchigadzira zvigadzirwa zvekubatana kwepamusoro-kushushikana kwemuviri, dambudziko rakakosha kudzivirira kuneta kwezvinhu. Munyika yezvigadzirwa zvemhuka, heavy duty rubber matoyi embwa shanda semuenzaniso wekutanga weyakanyanya kukanganisa elastomer application. Matoyi aya anoiswa pasi pe "point loading" -kumanikidzwa kukuru, kwakadzika kwezino rembwa - izvo zvingaita kuti mapurasitiki akajairwa aparadze kana kuti marabha akaderera kubvaruka.
Iko kushandiswa kweyakanyanya kukanganisa elastomers kunogadzirisa izvi kuburikidza neyakasiyana dhizaini dhizaini. Nekuti zvinhu izvi zvine kudyidzana kwakasimba pakati peanochinjika mamorekuru cheni, simba kubva pakurumwa rinogovaniswa kuyambuka matrix yese yepolymer pane kunyudzwa padanho rekukanganisa. Iyi "energy displacement" chiratidzo chepamusoro-yekupedzisira tekinoroji yekugadzirira. Nekuona kuti zvinhu zvacho zvine tembiricha yakaderera yegirazi, mainjiniya anogadzira toyi rinoramba richichinjika uye risingapindiri zvisinei nenharaunda. Ingave toyi yacho inoshandiswa museri kwechivanze kana mupaki yakanyura nezuva, simba rayo rakakwirira rinoramba riripo, kudzivirira kuumbwa kweshadhi dzakapinza, dzine ngozi.
Dynamic Performance yeRubber Imbwa Toys yeAggressive Chewers
Kune yakasarudzika subset yemusika-iyo "simba chewer" -kusimba kusimba hakuna kukwana. Iko kushandiswa kweyakanyanya kukanganisa elastomers mukati matoyi embwa yerabha yevanotsenga vane hasha inoda kutarisisa pa "low heat generation." Kana imbwa ichiramba ichitsenga, kukandirana kwemukati mukati mechinhu kunogona kutungamira mukudziya kwekupisa, uko kunowanzo kupfavisa nekunetesa akajairwa elastomers.
Nekudaro, yakakwira mhedzisiro elastomers inogadzirwa kune yakanakisa simba zvivakwa. Vanochengetedza simba ravo repamusoro pakupisa kwepamusoro, zvichireva kuti chimiro chechimiro chetoyi hachidzikisire panguva yekutsenga kwakanyanya. Uku kugadzikana kwekupisa kunowanikwa kuburikidza nekunyatso kudzora maitiro panguva yekugadzira zvinhu. Nekushandisa kugovera huremu hwema molecular, vagadziri vanogona kugadzira chigadzirwa chinonzwa "chakapfava" zvakakwana kuti chibatanidze mhuka asi ine molecular "yakaoma" zvakakwana kuramba puncturing. Iyi chiyero chepamusoro elasticity uye kusimba kwesimba ndiyo inobvumira matoyi aya kuti ararame mwedzi yekushungurudzwa apo vamwe vanokundikana mumaminetsi.
Izvo Zvimiro Zvakanakira zveSolid Rubber Imbwa Toys
Mune akawanda maindasitiri uye evatengi maapplication, iyo "yakasimba" chimiro chechikamu ndiro simba rayo guru. Imbwa dzakasimba matoyi embwa shandisa huremu hweyakanyanya kukanganisa elastomers kupa huremu uye tactile mhinduro iyo isina matoyi isingaenderane. Kubva pakuona kwechishandiso, huremu hwakasimba hwemhando yepamusoro-soro hunoita sechinhu chinokatyamadza.
Iyo tekinoroji yekugadzirira inoshandiswa kune aya mafomu akasimba inovimbisa kuti hapana mukati mukati memhepo homwe kana "voids" inogona kushanda semapoinzi ekukundikana. Nekuti izvo zvinhu zvinosangana neRoHS 2.0, REACH, uye PFAS-yemahara mwero, iyo yakakwira density yetoyi haiuye nemubhadharo wekuchengetedzwa kwemakemikari. Kuvakwa kwakasimba kunobvumira kubatanidzwa kweiyo yakaoma pamusoro geometries-yakadzika grooves kana nubs yakasimudzwa-inoramba ichishanda nekufamba kwenguva. Muchiitiko chepamusoro-soro, senge chitoyi chiri kukandwa pamadziro ekongiri kana kubatwa neshaya dzine simba, elastomer yakasimba inochengetedza chimiro chayo uye "inodzokororwa" nekuda kwekureruka kwepamusoro kunowanikwa mumagadzirirwo ayo mamorekuru.
Kutevedza Kwezvakatipoteredza muRubber Pet Toys
Kushandiswa kwechinhu chero chipi zvacho mumamiriro eimba kunofanirwa kuverengera kuchengetedzwa uye mitemo yezvakatipoteredza. Yakakwirira maitiro elastomer zvinhu zviri kumberi kwe "girinhi" polymer chemistry. Mukugadzirwa kwe rabha dzinovaraidza matoyi , zvakakosha kuti zvinhu zvirege kudonha makemikari anokuvadza.
Nekutevedzera maPAHs, POPs, TSCA, uye REACH mirau, aya elastomer anopa imwe isiri-chepfu kune yechinyakare PVC kana marabha anogadzirwa nemakemikari. Izvi zvinonyanya kukosha kune zvigadzirwa zvinowanzoitika mumuromo memhuka inovaraidza. Iyo tekinoroji yekugadzirira inobvumira kugadzirwa kwemhando yepamusoro-yekuita zvinhu pasina kudiwa kwehupfu plasticizers kana heavy metal stabilizers. Nekuda kweizvozvo, iyo "simba repamusoro" rechinhu chinofananidzwa ne "kuchengetedzeka kwepamusoro," zvichiita kuti ive mumiriri akakodzera wezvigadzirwa zvinoda kusimba kwemuviri uye kusagadzikana kwebiological.
Thermal Kugadzikana uye Yakakwira Elasticity muKutamba Kwekunze
Imwe yeanonyanya kunakidza mashandisiro eyakanyanya kukanganisa elastomers kuita kwavo mumamiriro ekunze akanyanya. Rabha rechinyakare rinowanzoita kuoma uye brittle mukutonhora, kana gummy uye kupera simba mukupisa. Yakakwirira maitiro elastomers, zvisinei, akagadzirirwa kuchengetedza yakakwira elasticity pakudzika kwakadzika uye kusimba kwepamusoro pakupisa kwakanyanya.
Hunhu uhu hwakakosha kune heavy duty rubber matoyi embwa yakagadzirirwa kushandiswa kunze. Mumamiriro ekunze echando, chitoyi chakagadzirwa kubva pazvinhu izvi hachizotsemuka kana chakadonhedzwa pasi pechando. Sezvineiwo, mukupisa kwezhizha, zvinhu zvacho hazvizorasikirwe ne "snap" kana kuve nengozi kupfava. Iyi yakafara yekushanda tembiricha yemhando imhaka yekuchinjika kwema molecular cheni inokwanisa kufamba zvakasununguka pasina kurasikirwa neintermolecular bond. Izvi zvinoita kuti mashandiro echigadzirwa ave ekufungidzira uye akachengeteka mazuva 365 pagore, zvisinei nenzvimbo.
Paunenge uchigadzira zvigadzirwa zvekubatana kwepamusoro-kushushikana kwemuviri, dambudziko rakakosha kudzivirira kuneta kwezvinhu.
