I-Rotomolding yeyona ndlela ikhethwayo yokuvelisa iimveliso zeplastiki ezingenanto ezininzi ezisetyenziswa kubomi bethu bemihla ngemihla, kwaye eneneni lelinye lawona mashishini akhula ngokukhawuleza kushishino lweplastiki kule minyaka ilishumi idlulileyo.
Ngokungafaniyo nezinye iindlela zokucubungula, ukufudumeza, ukunyibilika, ukubumba, kunye nokupholisa izigaba zokubumba okujikelezayo kwenzeka emva kokuba i-polymer ifakwe kwi-mold, oku kuthetha ukuba akukho xinzelelo lwangaphandle olufunekayo ngexesha lokubumba.
Umngundo ngokwawo uqhele ukwenziwa nge-aluminiyam etyhidiweyo, i-aluminiyam yomatshini weCNC, okanye intsimbi.Xa kuthelekiswa nomngundo osetyenziswa kwezinye iindlela (ezifana nenaliti okanye ukubumba iblowu), ukubumba akubizi mali ininzi.
Inkqubo yokubumba ejikelezayo ilula, kodwa iguquguquka kakhulu.Okokuqala, i-cavity igcwele i-polymer powder (kuxoxwa kwicandelo elilandelayo).
I-oven ifudunyezwa malunga ne-300 ° C (572 ° F) ngelixa i-mold ijikeleza kwii-axes ezimbini ukuze isasaze ngokulinganayo i-polymer.Umgaqo osisiseko kukuba i-powder particles (ngokuqhelekileyo malunga ne-150-500 microns) iya kudibanisa ukuze yenze umkhiqizo ogqityiweyo oqhubekayo.Isiphumo sokugqibela semveliso sixhomekeke ngokubalulekileyo kubukhulu bepowder particles.
Ekugqibeleni, ukubumba kupholile kwaye imveliso ikhutshwe ukuze igqitywe.Ixesha lokujikeleza kwenkqubo ye-rotomolding esisiseko inokuhluka kwimizuzu engama-20 ukuya kwi-1 iyure, kuxhomekeke kubukhulu kunye nobunzima bemveliso.
Ngokuxhomekeke kwimveliso yokugqibela efunekayo, iintlobo ezahlukeneyo zeepolima zeplastiki zingasetyenziswa kwi-rotomolding.
Enye iplastiki esetyenziswa ngokuqhelekileyo yi-polyethylene (PE) kuba inokumelana namaqondo obushushu aphezulu ixesha elide kwaye ayibizi kakhulu.Ukongeza, uxinaniso oluphantsi lwe-PE lubhetyebhetye kakhulu kwaye luyamelana nokuqhekeka.
Abenzi bomngundo baqhele ukusebenzisa i-ethylene-butyl acrylate kuba le nto inokumelana nokuqhekeka kunye namandla kumaqondo obushushu aphantsi.Njengoninzi lwe-thermoplastics, inenzuzo eyongeziweyo yokuba kulula ukuyiphinda isetyenziswe
Nangona i-polypropylene iyiplastiki esetyenziswa ngokubanzi, ayilona khetho lokuqala lwababumbi abaninzi.Isizathu kukuba le mpahla iba yi-brittle kufuphi nobushushu begumbi, ngoko ke abavelisi banexesha elincinane lokubumba imveliso.
Iimveliso ezininzi zemihla ngemihla ziveliswa kusetyenziswa iindlela zokubumba ezijikelezayo, njengemveliso eyenziwe ngokwezifiso.Eminye imizekelo inikwe ngezantsi:
I-Rotomolding yindlela esebenzayo kakhulu yokubumba, evumela abavelisi ukuba bangavelisi kuphela iimveliso ezihlala ziqinile kunye nezithintelo zoyilo ezincinci, kodwa kunye nokuvelisa ngendlela ehambelana nokusingqongileyo ngexabiso eliphantsi.Ukongeza, iimveliso ezinkulu zinokuveliswa ngokulula ngendlela eyongayo, kunye nemathiriyeli encinci echithwayo.
I-Rotomolding inokusekwa ngokukhawuleza, enokuthi ihlangabezane neemfuno ezingalindelekanga kwaye ivelise kwiibhetshi ezincinci.Inceda ukucutha uluhlu lwempahla kunye nokuphinda kusetyenziswe kwakhona, kuyenza ingabizi mali ininzi xa kuthelekiswa nokuvelisa, i-fiberglass, inaliti, ivacuum, okanye iindlela zokubumba.
Ukuguquguquka kokubumba okujikelezayo kukwayenye yeenzuzo zayo eziphambili.Yenza ukuba iimveliso zenziwe ngaphandle kwemigca ye-polymer weld, enemigangatho emininzi kunye nezitayile ezahlukeneyo, imibala kunye nokugqitywa komphezulu.I-Rotomolding ayinakukwazi ukufaka kuphela izinto ezifakiweyo, kodwa kunye neelogo, iigrooves, imilomo, abaphathi kunye nemisebenzi engaphezulu yokuhlangabezana noyilo oluyimfuneko kunye neemfuno zobunjineli.Ukongeza, ukusebenzisa le ndlela kunokwenza iintlobo ezahlukeneyo zeemveliso kunye kumatshini omnye.
UGary uphumelele kwiDyunivesithi yaseManchester ngesidanga sokuqala se-honours kwi-geochemistry kunye nesidanga se-master kwi-geoscience.Emva kokusebenza kwishishini lezimayini lase-Australia, uGary wagqiba ekubeni axhome iibhutsi zakhe zejiyoloji kwaye endaweni yoko aqale ukubhala.Xa engaphuhlisi umxholo wezihloko kunye nolwazi, uhlala umbona uGary edlala isiginci sakhe asithandayo, okanye ubukele i-Aston Villa Football Club iphumelele kwaye ilahlekelwe.
