Kulimba kwa ulusi wowongoka monga kulimbitsa mgwirizano m'zaka za m'ma 90 m'zaka za zana la 20 ndizochitika zaposachedwa kwambiri padziko lonse lapansi, mgwirizano wolimba wodalirika, wolimba kwambiri wolimba, wofanana ndi ulusi wokanda mawondo, komanso umakhala wosavuta kumanga. , liwiro makhalidwe, motero anapereka zitsulo zowongoka ulusi kulumikiza luso mgwirizano anabweretsa khalidwe prance.Pakali pano, m'dziko lathu pali mitundu yambiri yolumikizira ulusi wowongoka.

Cholumikizira ulusi wowongoka chimaphatikizapo kusokoneza cholumikizira chowongoka ndi ulusi wowongoka.Njira ziwirizi zimasankha njira zosiyanasiyana zopangira, kupititsa patsogolo mphamvu yonyamula ulusi womaliza wachitsulo, kuti ifike polumikizana ndi kulimbikitsa zinthu zoyambira ndi zolinga zina zamphamvu.

Kusokoneza ulusi wowongoka: mgwirizano wopangidwa ndi kutsekeka kwa ulusi wowongoka ndi ulusi wolumikizira womwe umapangidwa posokoneza chitsulo.Njira ndi:

Choyamba, mapeto azitsulo azitsulo amakhumudwa ndi zipangizo zosokoneza, ndiyeno ulusi umakonzedwa.The awiri ulusi si osachepera awiri a zitsulo bala m`munsi zakuthupi, kuti olowa ndi m`munsi zakuthupi kufika mphamvu ofanana.Ulusi wowongoka wakunja wosokoneza mgwirizano, mapeto ake achitsulo amakhala ndi kusokoneza komanso kuzizira.Cholinga chachikulu cha kukhumudwa kotentha ndikuchotsa kupsinjika kwamkati panthawi yachisokonezo, koma mtengo wa zipangizo zotentha ndizokwera kwambiri.M'dziko lathu, kumapeto kwazitsulo zolumikizira ulusi wowongoka kumakhala kozizira kwambiri, komwe kumafunikira kwambiri ductility yazitsulo zachitsulo.Pazitsulo zachitsulo zomwe zimakhala ndi ductility yochepa, khalidwe lokhumudwitsa ndilovuta kulamulira, ndipo n'zosavuta kuwoneka ngati mawonekedwe ophwanyika.

Ubwino wosokoneza ulusi wowongoka ndi mphamvu yayikulu, liwiro lomanga malo, kuchepa kwa ogwira ntchito, chitsulo chowongoka chamutu zonse zopangiratu pasadakhale, kugwirizana kwa malo opangira unsembe.The akusowa lagona ndondomeko kukhumudwitsa n'zosavuta kuoneka kukhumudwitsa maonekedwe, kamodzi kukhumudwitsa m'pofunika kudula kachiwiri kukhumudwitsa;Panthawi yokhumudwitsa, kupsinjika kwamkati kumachitika, kukhumudwa kwina kwachitsulo kumachepa, ndipo kumakhala kosavuta kupanga mawonekedwe osweka.Kukonza ulusi wa screw kumafuna njira ziwiri ndi zida ziwiri kuti amalize.

Cholumikizira ulusi wowongoka: cholumikizira chomwe chimapangidwa ndi kuluma kwa ulusi wowongoka ndi ulusi wolumikizira womwe umapangidwa ndikugudubuza mwachindunji kapena kufinya (kugudubuza) nthiti kumapeto kwachitsulo kapena kuvula nthiti.

Atatu, manja kukankha olowa: pambuyo kukankha mphamvu kuti olowa pulasitiki mapindikidwe malaya zitsulo ndi nthiti zitsulo zolimba occluded olowa.Pali njira ziwiri, kulumikizana kwa radial kneading ndi kulumikizana kwa axial kneading.Chifukwa kumanga malo ophatikizana axial sikuli koyenera ndipo mtundu wolumikizana nawo sukhazikika, sunakhazikitsidwe;Maluso ophatikizira ma radial ndi zolumikizira zagwiritsidwa ntchito kwambiri.Tsopano zolumikizira manja zomwe zimagwiritsidwa ntchito pantchitoyi ndi zolumikizira zozungulira.Chifukwa cha khalidwe lake labwino kwambiri, zolumikizira zokanda manja zakhala zikugwiritsidwa ntchito kwambiri pa zomangamanga ku China kuyambira kumayambiriro kwa zaka za m'ma 1990 mpaka pano.
