2.5 Chida Chokhazikika Chomanga
Kuumba jakisoni wachindunji ndiukadaulo womwe umapangidwa ndi Eth Zurich: Madzi osinthika, omwe angasinthidwe a electrolyte amasakanikirana, ndiye kuti slurry imalowetsedwa mu nkhungu yopanda mphamvu.

Lamulirani ntchito yomwe imachitika pakusintha kwa mankhwala panthawi ya njirayi. Zomwe zimachitika pambuyo pa jakisoni kuchitika pang'onopang'ono, mafayilo amasungidwa otsika, ndipo zomwe zimachitika zimathamangitsidwa pambuyo pa jekeseni ataumba, ndipo madziwo amasunthika, ndipo madziwo amasinthidwa kukhala thupi lolimba. Thupi lobiriwira lomwe lili ndi chuma chabwino komanso mphamvu zimatha kufikira 5Kpa. Thupi lobiriwira lizikayikidwa, louma ndikuchimwa kuti lipange gawo limodzi la mawonekedwe omwe mukufuna.

Ubwino wake ndichakuti sizikufunika kapena zimangofunika zowonjezera zowonjezera (zosakwana 1%), thupi lobiriwira siliyenera kukhala chipongwe, kachulukidwe kakang'ono kambiri (55% ~ 70%), ndipo imatha kupanga zigawo zamisala. Choyipa chake ndikuti zowonjezera ndizokwera mtengo, ndipo mpweya umasulidwa nthawi yomwe achita.

2.6 Mwezi Wowumba
Kuumba jakisoni wakhala ukugwiritsidwa ntchito popanga zopangidwa ndi pulasitiki ndi kuumba kwa zitsulo. Njirayi imagwiritsa ntchito kutentha kwapadziko lapansi kwa ormoplastics kapena kutentha kwambiri kwa ormoctive. Ufa ndi onyamula zachilengedwe amasakanizidwa pazida zosakanikirana zapadera, kenako ndikulowetsedwa mu nkhungu pansi pa kukakamizidwa kwambiri (makumiwo kupita ku mazana a MPA). Chifukwa cha kukakamizidwa kwakukulu, zomwe zapezedwa ndi zomwe zimapangidwira kukhala ndi kukula kwake, kosalala komanso kokhazikika; Kugwiritsa ntchito zida zapadera zowumba kumapangitsa kuti ntchito yopanga bwino.

Chakumapeto kwa zaka za m'ma 1970 ndi kumayambiriro kwa 1980s, njira youmba jakisoni idayikika pakuumba kwa matenda a ceramic. Njirayi imazindikira kukula kwa pulasitiki kwa zida zosabereka powonjezera zinthu zambiri zachilengedwe, zomwe ndizofala pulasitiki. Mu ukadaulo wopanga jakisoni, kuwonjezera pa zolengedwa za thermoplastic (monga polruthylene), thermosetive ortics, mafuta ogulitsa madzi kuti azitha kusintha magazini yam'madzi ndikuwonetsetsa mtundu wa jakisoni wowumbidwa.

Njira youmba ya jakisoni imakhala ndi zabwino zokhala ndi kuchuluka kwazovala zokha komanso kukula kwa kukula kwamphamvu. Komabe, zolengedwa zomwe zimapezeka m'thupi lobiriwira m'thupi jakisoni-zopangidwa ndi midzi ndizokwera kwambiri monga 50VOL%. Zimatenga nthawi yayitali, ngakhale masiku angapo ku masiku angapo, kuti muchepetse zinthu izi potsatira zolakwika pambuyo pake, ndipo ndizosavuta kuyambitsa zolakwika.

2.7 jakisoni wa Colloidal akuumba
Pofuna kuthana ndi mavuto a kuchuluka kwa zinthu zachilengedwe zomwe zikuwonjezeredwa komanso zovuta kuthetsa zovuta zakuunikiratu, ndipo podziimira adapanga jakisoni wa colratic Slurrype. kupanga.

Lingaliro lalikulu ndikuphatikiza kuwumba kokongoletsa kwa colloidal, pogwiritsa ntchito zida za jakisoni wa jakisoni ndi njira zatsopano zokongoletsera zopangidwa ndi Colloidal in-Studical Kuundana. Njira yatsopanoyi imagwiritsa ntchito zosakwana 4wt.% Yazinthu zachilengedwe. Mlingo wocheperako kapena wopangidwa mwamphamvu mu kuyimitsidwa kwamadzi kumagwiritsidwa ntchito mwachangu kwa polymerization kwa organic monomers popanga mafupa a cell. Zina mwa izo, osati nthawi yopuma yokha yomwe imafupikitsidwa kwambiri, komanso mwayi wosweka deginalidwe kamachepetsedwa kwambiri.

Pali kusiyana kwakukulu pakati pa jakisoni wa jakisoni wa ceramics ndi kuwumba kokongoletsa. Kusiyana kwakukulu ndikuti kale ndi gulu la pulasitiki, ndipo zomaliza ndi zoumba, ndiye kuti slurry ilibe pulasitiki ndipo ndi zinthu zosabereka.
