Reverse extrusion teknoloji ndi mfundo yosankhidwa ya pepala lamkuwa

Ndi chitukuko cha chuma ndi sayansi ndi teknoloji, zofunika khalidwe la mankhwala extruded ndi apamwamba ndi apamwamba, ndi zofunika zina zapadera amaika patsogolo mbali zina, amene amalimbikitsa chitukuko mofulumira wapepala lamkuwareverse extrusion teknoloji.

Mtundu watsopano wa reverse extrusion process wa pepala lamkuwa loyenera zitsulo zosiyanasiyana ndi aloyi komanso zitsulo zina zidapangidwa.Malinga ndi zosowa, kapangidwe ka mkuwa pepala extruder nthawi zonse luso ndi bwino, ndipo n'zosiyana extruder ndi ntchito zosiyanasiyana ndi nyumba zosiyanasiyana amapangidwa.Malinga ndi zofunika za luso kupanga ndi khalidwe mankhwala, kufa ndi latsopano extrusion chida zipangizo reverse extruder ndi dongosolo latsopano amapangidwa.

Mfundo zazikuluzikulu za kusankha mkuwa pepala reverse extrusion luso: (1) malinga ndi otaya makhalidwe osiyana zitsulo extrusion, amene zipangizo ayenera kuonedwa ntchito n'zosiyana extrusion angadziŵike.Mwachitsanzo, kumbuyo kwa extrusion yamkuwa, mkuwa ndi ma aloyi ena, kutuluka kwachitsulo kumakhala pakati pa mtundu A ndi mtundu wa B, ndipo kusintha kwa kutentha ndi kupanikizika panthawi ya extrusion kumakhala kochepa kwambiri.Ndi opindulitsa kupititsa patsogolo kufanana kwa microstructure ndi katundu wa mankhwala extruded ntchito lathyathyathya kufa unlubricated n'zosiyana extrusion wa pepala mkuwa ndi aloyi mkuwa waya, bala, mbiri ndi chitoliro.

(2) Kukangana kwakunja kumakhala ndi chikoka chodziwikiratu pakuyenda kwa pepala lamkuwa.Kukangana kosiyanasiyana kwakunja kudzatsogolera kumitundu yosiyanasiyana yazitsulo.Chifukwa chake, pazinthu zomwe zimafunikira kudzoza ndi kutulutsa, ndizopindulitsa kugwiritsa ntchito reverse extrusion.

(3) N'zosiyana extrusion ndi oyenera kupanga extrusion wa pepala mkuwa ndi mwatsatanetsatane mkulu, dongosolo zabwino ndipo palibe coarse galasi galasi ndi yopapatiza extrusion kutentha osiyanasiyana.Mphamvu yomwe ikugwira ntchito pazitsulo panthawi yobwezeretsanso, ndi mphamvu yomwe ikugwira ntchito pazitsulo panthawi yochotsanso chingwe chamkuwa, palibe kusuntha kwachibale pakati pa billet yachitsulo ndi pepala lotulutsa.
