Nangona iiplastiki zineempawu ezininzi ezilungileyo, ayizizo zonke iintlobo zeeplastiki ezinokuba nazo zonke iimpawu ezilungileyo.Iinjineli zezixhobo kunye nabayili bemizi-mveliso kufuneka baqonde iipropathi zeeplastiki ezahlukeneyo ukuze bayile iimveliso zeplastiki ezigqibeleleyo.Ipropathi yeplastiki, inokohlulwa ibe yipropathi ebonakalayo esisiseko, ipropathi yomatshini, ipropathi eshushu, ipropathi yemichiza, ipropathi yokukhanya kunye nepropathi yombane, njl.Ziiplastiki ezinamandla abalaseleyo, ukuxhathisa impembelelo, ukumelana nobushushu, ukuqina kunye neempawu zokuchasana nokuguga.Ishishini laseJapan liza kuyichaza ngokuthi "inokusetyenziswa njengenxalenye yesakhiwo kunye noomatshini beeplastiki ezisebenza kakhulu, ukumelana nobushushu ngaphezu kwe-100 ℃, esetyenziswa ikakhulu kwishishini".
Ngezantsi siza kudwelisa ezinye ezisetyenziswa ngokuqhelekileyoizixhobo zokuvavanya:
1.Melt Flow Index(MFI):
Isetyenziselwa ukulinganisa isantya sokunyibilika kwexabiso le-MFR yeeplastiki ezahlukeneyo kunye neereyini kwimeko yokuhamba kwe-viscous.Ifanelekile kwiiplastiki zobunjineli ezifana ne-polycarbonate, i-polyarylsulfone, iiplastiki ze-fluorine, i-nylon kunye nokunye kunye nobushushu obuphezulu bokunyibilika.Kwakhona ifanelekile i-polyethylene (PE), i-polystyrene (PS), i-polypropylene (PP), i-resin ye-ABS, i-polyformaldehyde (i-POM), i-polycarbonate (i-PC) i-resin kunye nolunye ubushushu obunyibilikayo beplastiki luvavanyo oluphantsi.Ukuhlangabezana nemigangatho: ISO 1133,ASTM D1238,GB/T3682
Indlela yovavanyo kukuvumela amasuntswana eplastiki anyibilike abe lulwelo lweplastiki ngexesha elithile (imizuzu eli-10), phantsi kobushushu obuthile kunye noxinzelelo (imigangatho eyahlukeneyo yezinto ezahlukeneyo), kwaye emva koko aphume nge-2.095mm ububanzi benani leegram. (g).Ixabiso elikhulu, ngcono ukusetyenzwa kwezinto zeplastiki, kwaye ngokuphambeneyo.Umgangatho wovavanyo olusetyenziswa ngokuqhelekileyo yi-ASTM D 1238. Isixhobo sokulinganisa lo mgangatho wovavanyo yi-Melt Indexer.Inkqubo ethile yokusebenza yovavanyo yile: i-polymer (iplastiki) izinto eziza kuvavanywa zifakwe kwi-groove encinci, kwaye isiphelo se-groove sidibaniswe netyhubhu encinci, ububanzi bayo bu-2.095mm, kunye nobude be-groove. ityhubhu yi-8mm.Emva kokufudumeza kwiqondo lokushisa elithile, isiphelo esiphezulu sezinto eziluhlaza sigxininiswe phantsi ngobunzima obuthile obusetyenziswe yipiston, kwaye ubunzima bezinto eziluhlaza bulinganiswa ngaphakathi kwemizuzu eyi-10, isalathiso sokuhamba kweplastiki.Ngamanye amaxesha uya kubona ukumelwa kwe-MI25g / 10min, oku kuthetha ukuba i-25 grams yeplastiki ikhutshwe ngemizuzu eyi-10.Ixabiso le-MI leeplastiki ezisetyenziswa ngokuqhelekileyo liphakathi kwe-1 kunye ne-25. Inkulu i-MI, i-viscosity encinci yezinto eziluhlaza zeplastiki kunye neyona nto incinci ye-molecular weight;ngaphandle koko, i-viscosity enkulu yeplastiki kunye nobunzima be-molecular.
2.Umatshini woVavanyo lwe-Universal Tensile (UTM)
Umatshini wokuvavanya imathiriyeli yendalo yonke (umatshini wokuzibamba) : ukuvavanya ukuqina, ukukrazula, ukugoba kunye nezinye iipropathi ezinomatshini wezinto zeplastiki.
Inokwahlulwa ngokwezi ndidi zilandelayo:
1)Tensile strength&Ukwandisa:
Amandla okuqina, okwakwaziwa njengamandla okuqina, abhekisa kubungakanani bamandla afunekayo ukolula izinto zeplastiki ukuya kumlinganiselo othile, ngokuqhelekileyo ubonakaliswa ngokobungakanani bamandla kwindawo nganye yeyunithi, kwaye ipesenti yobude obululayo bubude.Amandla okuqina Isantya se-tensile somzekelo sidla ngokuba yi-5.0 ~ 6.5mm/min.Indlela yokuvavanya eneenkcukacha ngokwe-ASTM D638.
2)Amandla athambileyo&Ukugoba amandla:
Amandla okugoba, okwakwaziwa njengamandla e-flexural, asetyenziswa ikakhulu ukumisela ukuxhathisa okuguquguqukayo kweeplastiki.Inokuvavanywa ngokuhambelana nendlela ye-ASTMD790 kwaye ihlala ibonakaliswa malunga nokuba mangaphi amandla kwindawo nganye.Iiplastiki ngokubanzi ukuya kwi-PVC, i-Melamine resin, i-epoxy resin kunye namandla okugoba i-polyester yeyona nto ingcono.I-Fiberglass iphinda isetyenziswe ekuphuculeni ukumelana nokusonga kweeplastiki.Ukugoba u-elasticity kubhekiselele kuxinzelelo lokugoba oluveliswa ngokweyunithi yesixa se-deformation kuluhlu olulastiki xa umfuziselo ugobile (indlela yovavanyo efana namandla okugoba).Ngokubanzi, okukhona ukugoba ukuqina, kokukhona ukuqina kwezinto zeplastiki ngcono.
3)Amandla acinezelayo:
Amandla oxinzelelo abhekisa kwisakhono seeplastiki ukumelana noxinzelelo lwangaphandle.Ixabiso lovavanyo linokumiselwa ngokwendlela ye-ASTMD695.I-Polyacetal, i-polyester, i-acrylic, i-urethral resins kunye ne-meramin resins zineempawu ezibalaseleyo kule nkalo.
3.Umatshini wokuvavanya impembelelo yeCantilever/ Skuthetha ukuba umatshini wokuvavanya impembelelo yomqadi oxhaswayo
Isetyenziselwa ukuvavanya ukuqina kwempembelelo yezinto ezingezizo ezentsimbi ezifana nephepha leplastiki eliqinileyo, umbhobho, izinto ezinokwakheka okukhethekileyo, inayiloni eyomeleziweyo, ifayibha yeglasi eyomeleziweyo yeplastiki, i-ceramic, ilitye elityhidiweyo lokugquma umbane, njl.
Ngokuhambelana nomgangatho wamazwe ngamazwe we-ISO180-1992 "iplastiki - ukuzimisela kwamandla empembelelo ye-cantilever yezinto ezinzima";Umgangatho wesizwe we-GB/ T1843-1996 "indlela yokuvavanya impembelelo yeplastiki yeplastiki enzima", umgangatho woshishino lomatshini JB/ T8761-1998 "umatshini wokuvavanya impembelelo yeplastiki ye-cantilever".
4.Uvavanyo lokusingqongileyo: ukulinganisa ukumelana nemozulu yezinto eziphathekayo.
1) I-incubator yeqondo lokushisa rhoqo, ubushushu obungaguqukiyo kunye nomatshini wokuvavanya ukufuma zizixhobo zombane, i-aerospace, i-automotive, izixhobo zasekhaya, ipeyinti, imboni yeekhemikhali, uphando lwezenzululwazi kwiindawo ezifana nokuzinza kobushushu kunye nokuthembeka kwezixhobo zokuvavanya ukufuma, eziyimfuneko kumashishini amashishini, iindawo eziphambili, iimveliso semi-ezigqityiweyo, zombane, i-elektroniki kunye nezinye iimveliso, iinxalenye kunye nemathiriyeli ubushushu obuphezulu, ubushushu obuphantsi, ukubanda, ukufuma kunye neqondo elishushu okanye uvavanyo rhoqo lobushushu kunye nokufuma kwemekobume.
2) Ibhokisi yovavanyo yokuguga echanekileyo, ibhokisi yovavanyo yokuguga ye-UV (ukukhanya kwe-ultraviolet), ibhokisi yovavanyo lobushushu obuphezulu kunye nesezantsi,
