Rotomolding ndiyo nzira inosarudzika yekugadzira akawanda mapurasitiki epurasitiki anoshandiswa muhupenyu hwedu hwezuva nezuva, uye ndiyo imwe yemaindasitiri ari kukurumidza kukura muindasitiri yepurasitiki mumakore gumi apfuura.
Kusiyana nedzimwe nzira dzekugadzirisa, kudziya, kunyunguduka, kuumba, uye kutonhora kwematanho ekutenderera kunoitika mushure mekunge polima yaiswa muforoma, zvinoreva kuti hapana kumanikidzwa kwekunze kunodiwa panguva yekuumbwa.
Iyo mold pachayo inowanzogadzirwa neakakandirwa aluminium, CNC machined aluminium, kana simbi.Zvichienzaniswa nezviumbwa zvinoshandiswa mune dzimwe nzira (zvakadai sejekiseni kana kuputira), zviumbwa hazvidhure.
Rotational molding process iri nyore, asi inosiyana zvakanyanya.Kutanga, gomba rinozadzwa nepolymer yehupfu (inokurukurwa muchikamu chinotevera).
Ovheni inozodziiswa kusvika pa300°C (572°F) ukuwo mold ichitenderera pamatemo maviri kuti igovane polima.Nheyo yakakosha ndeyokuti zvidimbu zvehupfu (kazhinji zvingangoita 150-500 microns) zvichabatana pamwechete kuti zvigadzire chigadzirwa chinopfuurira chakapedzwa.Mhedzisiro yekupedzisira yechigadzirwa inoenderana zvakanyanya nehukuru hwehupfu hwehupfu.
Pakupedzisira, mold inotonhorera uye chigadzirwa chinotorwa kunze kwekupedzisa.Nguva yekutenderera kweiyo yakakosha rotomolding process inogona kusiyana kubva pamaminitsi makumi maviri kusvika paawa imwe, zvichienderana nehukuru uye kuoma kwechigadzirwa.
Zvichienderana nechigadzirwa chekupedzisira chinodiwa, marudzi akasiyana-siyana epurasitiki polymers anogona kushandiswa murotomolding.
Imwe purasitiki inowanzo shandiswa ndeye polyethylene (PE) nekuti inogona kutsungirira kutonhora kwakanyanya kwenguva yakareba uye isingadhuri.Uye zvakare, yakaderera-density PE inochinjika zvakanyanya uye inopokana nekutsemuka.
Vagadziri veMould zvakare vanowanzo shandisa ethylene-butyl acrylate nekuti chinhu ichi chine kutsemuka kuramba uye simba pakudziya kwakaderera.Kufanana neakawanda thermoplastics, ine mukana wakawedzerwa wekuve nyore kudzoreredza
Kunyange zvazvo polypropylene ipurasitiki inoshandiswa zvakanyanya, haisi iyo yekutanga sarudzo yevakawanda vanogadzira.Chikonzero ndechekuti chinhu ichi chinova brittle pedyo nekamuri tembiricha, saka vagadziri vane nguva shoma yekugadzira chigadzirwa.
Zvigadzirwa zvakawanda zvemazuva ese zvinogadzirwa uchishandisa nzira dzekutenderedza, sezvinenge zvakagadziridzwa zvigadzirwa.Mimwe mienzaniso inopiwa pazasi:
Rotomolding inzira inoshanda kwazvo yekuumba, iyo inobvumira vanogadzira kwete chete kugadzira zvigadzirwa zvinogara zvakanyanya zvine zvipingamupinyi zvekugadzira, asiwo kugadzira nenzira ine hushamwari kwezvakatipoteredza nemutengo wakaderera.Pamusoro pezvo, zvigadzirwa zvakakura zvinogona kugadzirwa zviri nyore nenzira ine hupfumi, nezvinhu zvishoma zvakaraswa.
Rotomolding inogona kukurumidza kumisikidzwa, iyo inogona kusangana zvisingatarisirwi zvinodiwa uye kuburitsa mumadiki madiki.Inobatsira kudzikisira hesitori uye inogona kudzokororwa, ichiita kuti ive yakachipa zvichienzaniswa nekugadzira, fiberglass, jekiseni, vacuum, kana kuvhuvhuta nzira.
Izvo zvakasiyana-siyana zvekutenderera kuumbwa zvakare chimwe chezvakanakira zvakanakira.Inogonesa kuti zvigadzirwa zvigadzirwe pasina polymer weld mitsara, ine akawanda akaturikidzana uye akasiyana masitaera, mavara uye pamusoro pekupedzisira.Rotomolding haingogone kugashira chete kuisa, asiwo marogo, grooves, nozzles, maboss uye mamwe mabasa kusangana neinoda dhizaini uye engineering zvinodiwa.Pamusoro pezvo, kushandisa nzira iyi kunogona kuumba mhando dzakasiyana dzezvigadzirwa pamwechete pamushini mumwe.
Gary akapedza kudzidza kubva kuYunivhesiti yeManchester aine dhigirii rekutanga-kirasi yehonours mugeochemistry uye dhigirii re master mu geoscience.Mushure mekushanda muindasitiri yemigodhi yeAustralia, Gary akafunga kuturika bhutsu dzake dzejoji ndokutanga kunyora panzvimbo.Paanenge asiri kugadzira zvemusoro uye zveruzivo zvemukati, iwe unogona kazhinji kuona Gary achiridza gitare rake raanoda, kana kuona Aston Villa Nhabvu Club ichihwina nekurasikirwa.
