Uvavanyo lokuxinana kwezinto zesinyithi yindlela ephambili yokuvavanya iimpawu zazo zoomatshini kwaye lubaluleke kakhulu. Ngokulinganisa iiparameter ezifana namandla okuxinana, amandla okuvelisa, kunye nokwandiswa, kulinganisa amandla okuthwala umthwalo wezinto kunye neempawu zokuguqulwa kweplastiki. Ibonelela ngesiseko sokhuseleko soyilo lobunjineli kwaye iqinisekisa ukuthembeka kwesakhiwo. Ikwasebenza njengesixhobo esibalulekileyo sokulawula umgangatho, iqinisekisa uzinzo lweenkqubo zemveliso kwaye iqinisekisa ukuthotyelwa kwemigangatho yamazwe ngamazwe. Ngaphezu koko, inokuqikelela umngcipheko wokusilela kwezinto phantsi kwemithwalo enzima kwaye inike inkxaso yedatha ebalulekileyo ekuphuhlisweni kwezinto ezintsha.
Oku kulandelayo kuthelekiso lweendlela zovavanyo lokuxinanaimibhobho yentsimbi ethambileyokwayeImibhobho ye-SML, zombini ezi zinto zinceda ekuqinisekiseni umgangatho wemveliso kunye nokusetyenziswa kwayo ixesha elide kwiimeko ezahlukeneyo zokwenyani.
1. Iinguqulelo zeSampuli
Ubukhulu kunye nobubanzi bentonga yovavanyo lweesampuli zesinyithi ezithambileyo zezi zilandelayo:
| Uhlobo lokuphosa | Ububanzi obuqhelekileyo bebha yovavanyo (mm) | Ukuphambuka komda wobubanzi (mm) | Ukunyamezelana kobubanzi (mm) |
| Ubukhulu bodonga lombhobho wesinyithi othungelweyo (mm) e＜6 6≤e＜8 8≤e＜12 12≤e | 2.5 3.5 5.0 6.0 | ±0.06 | 0.03 |
| Imibhobho yesinyithi engashukumiyo, izixhobo, kunye nezixhobo: - Iisampulu zokuphosa ezidibeneyo: - Iisampulu zokuphosa ezahlulwe ngokwahlulahlula: Kwimizekelo enobukhulu obuyi-12.5 mm, ubukhulu bokubumba kufuneka bube ngaphantsi kwe-12 mm. Kwiisampulu ezinobukhulu obuyi-25 mm, ubukhulu bokubumba kufuneka bube yi-≥ 12 mm. | 5.0 6.0 12.0 okanye i-14.0 | ±0.06 ±0.06 ± 0.09 | 0.03 0.03 0.04 |
Qaphela: Ibha yovavanyo yenziwe ngesampulu eyenziwe ngomatshini, emele isinyithi kubukhulu obuphakathi besampulu. Ibandakanya inxalenye yesampulu. Ububanzi besilinda buboniswe kwitheyibhile engentla. Ubude begaji yebha yovavanyo buphindwe kahlanu ubuncinane ububanzi bayo. Isiphelo sebha yovavanyo kufuneka silungele ukufakwa kwisixhobo somatshini wovavanyo. Uburhabaxa bomphezulu wenxalenye yesampulu yebha yovavanyo yi-Rz ≤ 6.3.
Umbhobho we-SML wenziwe ngentsimbi engwevu kwaye isampuli yawo kufuneka ihambelane nomfanekiso olandelayo:
Qaphela: Ukuze ufumane iziphumo zovavanyo ezimele imveliso egqityiweyo kangangoko kunokwenzeka, isampuli yovavanyo kufuneka ithathwe kumbhobho we-SML okanye kwi-SML fitting kwaye inqunyulwe ngokuhambelana ne-axis yetyhubhu okanye i-fitting. Indawo yokuqala ye-cross-section yesampuli kufuneka ilinganiswe. Ububanzi kunye nobukhulu be-cross section kufuneka bulinganiswe ngokuchanekileyo ukuya kwi-0.1mm ngaphambi kovavanyo.
2. Umahluko kwinkqubo yovavanyo
Nangona zombini ezi vavanyo zokutsalwa kwentambo zenziwa kusetyenziswa umatshini wokuvavanya ukutsalwa kwentambo osetyenziswa kwihlabathi liphela, izixhobo ezisetyenziswayo zahlukile.Isixhobo sovavanyo lokuxinana kwentsimbi ethambileyo siboniswe ngezantsi:
Umbhobho we-SML kunye nomatshini wovavanyo lokuxinana kokufakelwa kuboniswe ngezantsi:
3. Umahluko phakathi kweziphumo zovavanyo kunye neempawu zezinto ezibonakalayo
Inkqubo yokunyibilikisa nokuvelisa intsimbi ethambileyo yimveliso yeminyaka yokuqokelelana kwetekhnoloji kunye nokusebenza ngokungqongqo. Inkampani yethu ivelisa imibhobho yentsimbi ethambileyo ekumgangatho ophezulu, enezinga le-spheroidization eliyi-90% nangaphezulu. Uvavanyo lokuxinana lubonisa amandla okuxinana phakathi kwe-460MPa kunye ne-490MPa, kunye nokwandiswa phakathi kwe-10% kunye ne-17%. Ngokwemigangatho ye-EN545 kunye ne-ISO2531, amandla okuxinana angama-420MPa nangaphezulu kunye nokwandiswa kwe-5% ukuya kwi-10% nangaphezulu kuthathwa njengokufanelekileyo. Amandla okuxinana aqhelekileyo kunye nokwandiswa zezi zilandelayo:
Iipayipi ze-SML kunye nezixhobo zenziwe ngentsimbi engwevu. Ulwakhiwo lwegrafiti ye-flake ngaphakathi kwentsimbi engwevu lufunxa ukungcangcazela kwamanzi, okubangela amanqanaba engxolo yokukhupha amanzi ubuncinane i-10dB ngaphantsi kweepayipi ze-PVC. Zikwabonelela ngokumelana okuhle kakhulu nobushushu obuphezulu, okungaphezulu kwe-1,000°C. Iiringi zerabha zokutywina zihlala zisebenza nokuba zikwi-70°C ngokuqhubekayo okanye i-120°C ephumayo ngokuqhubekayo, kunye nokuguquguquka kobushushu kuphela isinye kwisixhenxe kuneepayipi ze-PVC. Zikwabonelela ngamandla agqwesileyo okutsalwa, ukumelana nokuchaphazeleka, kunye nokumelana nokukrala, ubuncinane ngokuphindwe kahlanu kuneepayipi ze-PVC.
Ngokwemigangatho ye-EN877, iimpawu zoomatshini zemibhobho ye-SML kunye nokufakelwa zezi zilandelayo:
