Kuponyera zitsanzo zowonongeka - kuchuluka kwa njirayi ndi ntchito yaikulu

Ndondomeko yomwe kuponyedwa kwapadera kumapangidwira ndi njira yowumasulira zitsulo mu dziko losungunuka mu maonekedwe apadera amatchedwa "kuponyera ndalama."

Njira yamakono yopanga njirayi ndi yovuta. Choyamba, tifunika kupanga chitsanzo chapadera, chomwe chidzakhala, mwachitsanzo, chiwonetsero cha zomwe zidzasungunuka, ndiko kuti, zidzakhala chitsogozo chomwe chitukuko chidzachitike.

Kuti apange mchitidwe wapamwamba, akatswiri amagwiritsa ntchito zipangizo monga nkhuni ndi pulasitiki. Mu gawo la chitsanzo, chinthu chopangidwa ku fakitale ina chikhoza kuchita. Chinthu chotsatira ndicho kupanga matrix ndi nkhungu. Amangofunika kupanga kapangidwe ka jekeseni.

Nthawi zambiri nkhungu zimadzazidwa ndi stearin kapena sera, chifukwa zinthuzi zimakhala ndi pulasitiki, zomwe zimakupangitsani kuti mupeze mawonekedwe.

Kuonjezeranso pamafunikanso kuti muwone mawonekedwe atsopano - malo ogwira ntchito. Amapezeka ndi njira yosungunuka. Ndichifukwa chake dongosolo lonse limatchedwa "kuponyera ndalama."

Kuponyera kokha kumakhalabe mu chipolopolo chochokera ku chipangizo chapadera chomwe chingathe kutentha kwambiri, chomwe chithunzichi chimakonzedwa bwinobwino asanayambe kutsanulira. Pamapeto pake, antchito amachotsa nkhunguzo.

Mu kuponyedwa kwachidziwitso kwa zitsanzo zamalonda, stearin kapena sera imachotsedwa pogwiritsa ntchito madzi otentha. Zigobowo zomwe zimachokera ku ndondomekoyi, pitirizani kuchita sequentially masitepe a calcination ndikutsanulira chitsulo chosungunuka. Kutentha, zipolopolo zimatenthedwa kutentha nthawi zambiri kuposa madigiri 900 a Celsius, zomwe zimathandiza kuthetsa vuto la mankhwala omwe alowe m'kati mwake, omwe, ngati sangachotsedwe, amachepetsa ubwino wa mankhwala omwe amapangidwa pamtunduwu.

Mosiyana, ziyenera kudziŵika kuti chipolopolochi chiyenera kupangidwa motsutsana ndi kukana mitundu yosiyanasiyana ya mankhwala.

Ndiwo kuponyera ndalama Amakulolani kuti mutenge zotsatira za castings, zomwe zingakhale zingapo magalamu, kapena mwinamwake matani angapo. Kutalika kwa makoma ozungulira kumbali kungakhale hafu ya millimeter, yomwe ikugwirizana ndi miyezo yonse ya mayiko.

Ndi lingaliro la kuponyedwa kwa ndalama, motero, lingaliro la kuponyedwa kwachindunji likugwirizana mwachindunji. Zimatanthawuza kwathunthu mawonekedwe a castings ndi zotsirizira zopangidwa mu kukula ndi mawonekedwe.

Mchitidwe wa kuponyera ndalama ndi wotchuka kwambiri ku Russia komanso kudziko lonse lapansi. Palinso zomera zomwe zimapangitsa kuti pulasitiki ipangidwe.

Pogwiritsa ntchito ndondomeko yopanga ndalama, makina ndi zipangizo zosiyanasiyana zimayesedwa. Ndondomeko yamakono imaphatikizapo kupanga ndi kutsanulira nkhungu zopangidwa ndi zomangira zapamwamba, kuyanika kwawo, kuvala ndi kukonza zinthu zowonongeka ndi kupukuta kwa stearin, kuyeretsa zopangidwa ndi castings. Zonse zomwe tatchula pamwambapa ndizovuta komanso nthawi yowonongeka.
