Ubudlelwane phakathi kokungunda kwesitofu seplastiki kunye nesantya sokuncipha bunzima kwaye kuphenjelelwa zizinto ezininzi, kubandakanya:
1.Uhlobo lwezinto:Iiplastiki ezihlukeneyo zinemilinganiselo yokunciphisa i-shrinkage, enokuthi isuse kwi-0.5% ukuya kwi-2% enempembelelo enkulu ekuchanekeni kwe-dimensional kunye nomgangatho wamacandelo okugqibela.Nantsi imizekelo embalwa yemathiriyeli yeplastiki kunye namazinga awo aqhelekileyo okucutheka:
2.Polyethylene (PE):I-PE inezinga eliphantsi lokucutheka kwe-0.5% ukuya kwi-1%.Oku kuyenza ifaneleke kakuhle kwizicelo apho uzinzo lwe-dimensional lubalulekile, njengokupakishwa kunye nempahla yabathengi.
Ipolypropylene (PP):I-PP inomlinganiselo ophakathi wokucutheka we-0.8% ukuya kwi-1.5%.Esi sixhobo sisetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanya iimpahla zasekhaya, ukupakishwa, kunye nezixhobo zemoto.
I-Acrylonitrile-Butadiene-Styrene (ABS):I-ABS inomlinganiselo ophakathi wokucutheka we-1% ukuya kwi-1.5%.Esi sixhobo siqhele ukusetyenziswa kwizicelo apho ukuchasana kwempembelelo, ukuqina, kunye nozinzo lwe-dimensional kufuneka, njengezinto zokudlala, i-electronics, kunye neendawo zemoto.
Inayiloni (PA):Inayiloni inomlinganiselo ophezulu wokushwabana we-1.5% ukuya kwi-2%.Esi sixhobo sihlala sisetyenziselwa ukusetyenziswa koxinzelelo oluphezulu, njengeegiya kunye neebheringi, kunye nezicelo apho ukuzinza kwe-dimensional akuyona into ebalulekileyo.
2, Ubukhulu bodonga:
Ubukhulu bendonga yenye yezinto eziphambili ezinokuchaphazela ukushwabana kokubumba inaliti yeplastiki.Nantsi indlela:
Iindonga ezityebileyo zidla ngokuba namazinga aphezulu okucutheka,njengoko kufuneka izinto ezininzi zokuzalisa ukubumba, okukhokelela kwiqondo eliphezulu lokucutha.Ukuqina kwecandelo lodonga, ixesha elininzi elithathayo ukuze ubushushu buphele, nto leyo enokubangela isantya sokupholisa esicothayo kunye nokuncipha okuphezulu.
Ubunzima bodonga olungalinganiyo bunokubangela ukushwabana okungalinganiyo, njengoko iindawo ezahlukeneyo zenxalenye ziya kupholisa kwaye ziqiniswe kumazinga ahlukeneyo.Oku kunokubangela ukungqubana, ukugqwetheka, kunye nezinye izinto ezingachanekanga kwinxalenye yokugqibela.
Ukunciphisa i-shrinkage kunye nokufezekisa amanqanaba angaguqukiyo, akumgangatho ophezulu, kuye kufuneke ukwandiswa kobukhulu bodonga kunye nokusebenzisa iindlela zokulawula inkqubo ezifana nolawulo lobushushu, isantya esicothayo sokutofa, kunye nokuzaliswa okulinganayo kwemigodi yokubumba.Ukongeza, izixhobo zokulinganisa, ezinje ngohlalutyo lwento ephelelisiweyo (FEA), zinokusetyenziselwa ukuqikelela ukuncipha kunye nokwandisa uyilo lokubumba ukunciphisa impembelelo yalo kumgangatho wenxalenye.
3, Icandelo lejometri:
Ijometri yenxalenye yeplastiki inokuba nempembelelo enkulu ekunciphiseni ngenxa yokuba ichaphazela indlela iplastiki ehamba ngayo, ipholile, kwaye iqina ngaphakathi kokubumba kwayo.
Iijometri ezintsonkothileyo: Amalungu anejiyometri entsonkothileyo, njengee-undercuts, iipokotho ezinzulu, kunye neegophe, zinokukhokelela kwiindawo apho iplastiki ivaleleke khona kwaye ayikwazi ukushwabana ngokulinganayo.Oku kunokukhokelela kumazinga aphezulu okucutheka kwezi ndawo kwaye kunokubangela ukungqubana, ukugqwetheka, kunye nezinye izinto ezingachanekanga kwinxalenye yokugqibela.
Ukuhamba kwezinto: Indlela iplastiki ehamba ngayo kwaye igcwalise ukungunda inokuchatshazelwa yinxalenye yejometri.Ukuba iplastiki ayiqhubeki ngokulinganayo kuzo zonke iindawo zokubumba, inokubangela ukuba izinga eliphezulu lokucutha kwiindawo ezithile.
Izinga lokupholisa: Isantya sokupholisa seplastiki sikwachatshazelwa yinxalenye yejometri.Kwiindawo ezinejometri ezintsonkothileyo, iplastiki inokuthatha ixesha elide ukuba iphole kwaye iqine, nto leyo enokukhokelela kumazinga aphezulu okucutheka.
4,Iqondo lobushushu lokungunda:
Iqondo lokushisa lokungunda lichaphazela izinga apho iplastiki ipholisa kwaye iqina.Amaqondo obushushu aphezulu okungunda anokubangela ukucotha kokupholisa, okunokunyusa ukushwabana.Ngokuchaseneyo, amaqondo obushushu asezantsi okungunda anokukhokelela kumazinga okupholisa akhawulezayo, anokunciphisa ukucutheka kodwa anokubangela ukonyuka kwemfazwe kunye nokunye okungachanekanga kwinqanaba lokugqibela.
U-Xiamen Ruicheng uneqela elityebileyo leenjineli kwiindlela zokungunda inalitioko kubandakanya ukusebenzisa iindlela zokulawula inkqubo, njengeenkqubo zokulawula ubushushu kunye nezivamvo zobushushu bokungunda, kunye nokuphucula uyilo lokungunda kunye neemeko zokuqhuba ukuqinisekisa ukupholisa okufanayo kunye nomgangatho wenxalenye engaguqukiyo.
Inqaku le-Xiamen Ruicheng: iprototyping ngononophelo kunye novavanyo lunokunceda ekuchongeni imiba enokubakho kunye nokwandisa uyilo lokubumba kwiindawo ezingaguqukiyo, ezikumgangatho ophezulu.
