1.Bubble: chiitiko chinoputika chinoumba pamusoro pezvikamu zvakasvibiswa nekuda kwekubuda kwechisimba kwegesi.Iyo inonziwo blister, iko kukanganisa kwekuvhara.Nekuda kwekusakwanisa kupinza uye kushomeka kwemvura kweiyo firimu yekuputira yependi yakanyungudika, panguva yekuchembera kwekunze, nekuda kwesimba rekunaya kwemvura kana kunyorova kwenzvimbo, kune mvura inoyerera pasi pefirimu yekuputira, uye mushure mekuputika, iyo isingapindiki uye isingapindiki. mvura-yakapfava yekuputira firimu inoputika, ichigadzira mabhuru.Hunyoro hwepamusoro hwakakwira, hunyoro hwepakati hwakakwira, tembiricha yakanyanyisa, putty haina kuvharwa zvakanaka, uye nguva iri pakati pema layer haina kukwana.
2.Pinhole: Mushure mokunge firimu yekuputira yakaomeswa, pamusoro pesefa yepende ichaita pinhole, iyo yakafanana neganda pores.Chirema ichi chinonzi pinhole.Munguva yekuvaka yekupfira, iyo solvent uye mhepo inoputika nekukurumidza uye inopukunyuka kubva kune yakanyorova yekuputira firimu, iyo ichaita gomba diki.Panguva ino, firimu rakanyorova harina mvura yakakwana, iyo isingagoni kuenzana negomba duku, ichisiya gomba rakaita tsono.Kana paine chidimbu chemvura mupende kana solvent, mapinikoni anowanzoitika.Iyo diluent ichave yakanyatso kusarudzwa kudzivirira mvura uye mamwe masundries kubva mukusanganiswa, uye viscosity yekuvaka ichadzorwa panguva imwechete kuderedza kana kudzivirira kutaridzika kwepinholes.Asi kana iri dambudziko repinhole remvura-yakavakirwa pendi, ichave iri dambudziko remanyorerwo.
Iyo diluent inowedzerwa kushoma, viscosity yependi sefa yakakurisa, iyo yekupfekedza yakakora zvakanyanya, nguva pakati pematanho haina kukwana, iyo static nguva mushure mekunge pendi yanatswa haina kukwana, uye diluent inonyungudika zvishoma nezvishoma.
3.Pelleting: nzvimbo yekuvaka yekupfapfaidza sefa yekrini haina kuchena, iyo workpiece ine mafuta, mvura uye guruva, tsvina yakasanganiswa mumucheka haina kucheneswa, zvishandiso zvekupenda uye midziyo hazvina kuchena, pende haina kusanganiswa zvakakwana, uye nguva yekusefa uye nguva yekumira hazvina kukwana.
4.Shrinkage gomba: spray filter screen inonziwo gomba.Inoreva kuremara kwemakomba madiki akatenderera pafirimu rekuputira.Mushure mekuputirwa, iyo firimu yakanyorova inodonha panguva yekuenzanisa, ichisiya makomba akawanda eshrinkage ane hukuru hwakasiyana uye kugovera mushure mekuoma.Izvi zvinokonzerwa nemusiyano wekunetsana kwepasi pakati pekumusoro nepasi kwemufirimu wemvura uye kusaenzana kwakashata.Inogona kugadziriswa nekuwedzera zvakakodzera zvinoyamura kuenzana kana kudzika pasi tension solvents.
Iyo yepasi pasi yakasviba, iyo workpiece ine mafuta, mvura uye guruva, nezvimwewo. Iyo yepasi pasi yakanyanyisa kutsetseka, kugaya hakuna kukwana, tembiricha yekuvaka yakaderera kana hunyoro hwakanyanya.
5.Underbite: Paunenge uchipfapfaidza chidzitiro chesefa nejasi repiri repende, pendi ichangobva kuiswa inoruma firimu rakamboomeswa kubva musubstrate.Kana izvi zvikaitika, kupfeka kunozowedzera, kushanduka, kuderera, kuunyana, kuputika, kana kutorasikirwa nekunamatira uye kudonha.Iyo yekutanga uye yekupedzisira jasi haina kufananidzwa;Iyo solubility yekunyungudika kwependi yekupedzisa yakanyanya kusimba;Kana iyo primer isina kuoma zvachose, inokonzera "undercut".
Iyo primer uye pendi yekupedzisa haina kufananidzwa, kupindirana pakati pematanho hakuna kukwana, pasi pasi haina kuoma, iyo diluent yakanyanya kusimba, uye kupfeka kwakanyanyisa panguva imwe.
