2.Pinhole: Ma hope o ka maloʻo ʻana o ke kiʻi ʻoniʻoni, e hana ka ʻili o ka kānana pena i ka pinhole, e like me nā pores ʻili.Ua kapa ʻia kēia hemahema he pinhole.I ka wā o ka hoʻoulu ʻana, e vaporize koke ka solvent a me ka ea a pakele mai ke kiʻi ʻoniʻoni pulu, e hana i kahi puka liʻiliʻi.I kēia manawa, ʻaʻole lawa ka wai o ka kiʻi ʻoniʻoni, ʻaʻole hiki ke pae i ka lua liʻiliʻi, e waiho ana i kahi puka koila.Ke loaʻa kahi ʻano wai i loko o ka pena a i ʻole ka mea hoʻoheheʻe, ʻoi aku ka nui o nā pinhole.E koho pono ʻia ka mea hoʻoheheʻe e pale i ka hui ʻana o ka wai a me nā mea ʻē aʻe, a e mālama ʻia ka viscosity hana i ka manawa like e hōʻemi a pale ʻole i ke ʻano o nā pinholes.Akā inā ʻo ka pilikia pinhole o ka pena wai, ʻo ia ka pilikia formula.
Hoʻohui liʻiliʻi ka diluent, ʻoi aku ka nui o ka viscosity o ka kānana pena, ʻoi aku ka mānoanoa o ka uhi ʻana, ʻaʻole lawa ka wā ma waena o nā papa, ʻaʻole lawa ka manawa static ma hope o ka hoʻoheheʻe ʻia ʻana o ka pena, a lohi loa ka diluent.
3.Pelleting: ʻaʻole maʻemaʻe ke ʻano o ka hana ʻana o ka kānana kānana kānana, ʻo ka mea hana i loko o ka ʻaila, ka wai a me ka lepo, ʻaʻole i kānana ʻia nā mea haumia i hui pū ʻia i loko o ka uhi, ʻaʻole maʻemaʻe nā mea pena a me nā ipu, ʻaʻole i hui pū ʻia ka pena. a ʻaʻole lawa ka manawa kānana a me ka manawa kū.
4.Shrinkage hole: spray filter screen is also called pit.E pili ana i ka hemahema o nā lua poepoe liʻiliʻi ma luna o ke kiʻi uhi.Ma hope o ka hoʻopiliʻiaʻana o ka uhiʻana, e emi iho ke kiʻiʻoniʻoni maʻemaʻe i ka wā o ka hoʻolālāʻana, e waiho ana i nā puka liʻiliʻi me nāʻano likeʻole a me ka māheleʻana ma hope o ka maloʻoʻana.Ma muli o ka ʻokoʻa o ka ʻili o ka ʻili ma waena o nā ʻāpana o luna a me lalo o ka kiʻiʻoniʻoni pulu a me ka pae maikaʻi ʻole.Hiki ke hoʻoholo ʻia ma ka hoʻohui ʻana i nā mea kōkua hoʻohālikelike kūpono a i ʻole nā mea hoʻonā haʻahaʻa haʻahaʻa.
He lepo ka papa lalo, aia ka ʻaila, ka wai a me ka lepo i ka mea hana, a me nā mea ʻē aʻe.
5.Underbite: I ka wā e kāpīpī ai i ka pale kānana me ka lua o ka pena pena, nahu ka pena hou i ka kiʻiʻoniʻoni maloʻo mua mai ka substrate.Ke hana ʻia kēia, e hoʻonui ʻia ka uhi ʻana, e hoʻololi, e emi iho, e ʻāwīwī, e poʻo, a i ʻole e nalowale ka pili a hāʻule.ʻAʻole kūlike ke kapa mua a me ka hoʻopau;He ikaika loa ka solvent solubility o ka pena pena;Inā ʻaʻole maloʻo loa ka primer, e hana ia i ka "undercut".
ʻAʻole i kūlike ka pena mua a me ka hoʻopau ʻana, ʻaʻole lawa ka wā ma waena o nā papa, ʻaʻole maloʻo ka papa lalo, ikaika loa ka diluent, a mānoanoa loa ka uhi i ka manawa hoʻokahi.
