Abstract:Chinyorwa ichi chinoongorora mashandiro, kuwirirana, uye basa rekunamira padanho rakasiyana rekusanganisa, izvo zvinotibatsira kutonga zvirinani chikonzero chaicho chematambudziko ekuonekwa uye nekukurumidza kugadzirisa dambudziko.
Mukuita kwekuchinjika kurongedza kurongedza kugadzirwa kwecompositi, iyo "leveling" yekunamatira ine mhedzisiro yakakosha pamhando yecompositi.Nekudaro, tsananguro ye "leveling", matanho akasiyana e "leveling", uye kukanganisa kweiyo microscopic nyika pamhando yekupedzisira inoumbwa haina kunyatso kujeka.Ichi chinyorwa chinotora chinonamira chekunyungudutsa semuenzaniso wekukurukura zvinoreva, kuwirirana, uye basa rekuyera pamatanho akasiyana.
1.Chirevo chekuenzanisa
Kukwirisa zvimiro zveanonamira: Iyo inoyerera inoyerera kugona kweiyo yekutanga adhesive.
Kukwidziridzwa kwemvura yekushanda: Mushure mekunyungudika, kupisa uye dzimwe nzira dzekupindira, kugona kweadhesive inoshanda fluid kuyerera uye kupfava panguva yekuputira mabasa kunowanikwa.
Yekutanga kuenzanisa kugona: Kugona kuenzana kweanonamira mushure mekuputira uye pamberi pelamination.
Chechipiri kuenzanisa kugona: Kugona kweanonamira kuyerera uye kutsetseka mushure mekusanganiswa kusvika yakura.
2.Kudyidzana uye mhedzisiro yekuenzanisa pamatanho akasiyana
Nekuda kwezvinhu zvekugadzira zvakaita sehuwandu hwekunamira, yekumisikidza mamiriro, mamiriro ekunze (tembiricha, humidity), substrate state (kushushikana kwepamusoro, flatness), nezvimwe, iyo yekupedzisira composite mhedzisiro inogona zvakare kukanganiswa.Uyezve, kusiyanisa kwakawanda kwezvinhu izvi kunogona kukonzera kuchinja kukuru mukuonekwa kwemusanganiswa uye kunoguma nekuonekwa kusingagutsi, izvo zvisingagoni kungonzi zvinokonzerwa nekusagadzikana kwekunamira.
Naizvozvo, kana tichitaura nezve maitiro ekuyeresa pamhando yemubatanidzwa, isu tinotanga tafunga kuti zviratidzi zvezvinhu zviri pamusoro zvekugadzira zvinopindirana, kureva kuti, kusabvisa pesvedzero yezvikonzero zviri pamusoro uye kungokurukura kuenzanisa.
Kutanga, ngatigadzirise hukama pakati pavo:
Mumvura inoshandiswa, iyo inonyungudutsa yakakwira kupfuura iyo yekunamatira yakachena, saka viscosity yekunamatira ndiyo yakaderera pakati pezviratidzo zviri pamusoro.Panguva imwecheteyo, nekuda kwekusanganiswa kwepamusoro kwekunamatira uye kunyungudutsa, kushushikana kwayo kwepamusoro ndiyowo yakaderera.The flowability of adhesive working fluid ndiyo yakanakisisa pakati pezviratidzo zviri pamusoro.
Yekutanga chiyero ndipo apo kuyerera kwemvura inoshanda kunotanga kudzikira nekuomesa mushure mekuputira.Kazhinji, iyo node yekutonga yekutanga leveling iri mushure memubatanidzwa wemhepo.Nekukurumidza kubuda kweiyo solvent, iyo fluidity inounzwa neyakagadziriswa inokurumidza kurasika, uye viscosity yekunamatira iri pedyo neiyo yekunamatira yakachena.Raw raw leveling inoreva kuyerera kwenamira pachayo kana chinonyungudutsa chiri murubha chakapedzwa chabviswawo.Asi nguva yedanho iri ipfupi kwazvo, uye sezvo nzira yekugadzira inofambira mberi, ichakurumidza kupinda muchikamu chechipiri.
Yechipiri leveling inoreva kupinda mudanho rekukura mushure mekunge maitiro emubatanidzwa apera.Pasi pesimba rekushisa, chinonamira chinopinda padanho rekukurumidza crosslinking reaction, uye fluidity yaro inodzikira nekuwedzera kwedhigirii rekuita, pakupedzisira ichirasikirwa zvachose.
Naizvozvo, kazhinji, mvura yematanho mana ari pamusoro inoderera zvishoma nezvishoma kubva pakakwirira kuenda pasi.
3.The pesvedzero uye kudzora mapoinzi ezvakasiyana zvinhu mukugadzira maitiro
3.1Glue application yemari
Huwandu hweglue hwakaiswa hahusi hune chekuita nekuyerera kweglue.Mubasa remubatanidzwa, huwandu hwepamusoro hwekunamira hunopa yakawedzera kunamira mune inosanganiswa interface kuti isangane neiyo interface yekuda kwehuwandu hwekunamatira.
Semuenzaniso, panzvimbo yakaoma yekubatanidza, iyo inonamira inowedzera maburi emukati anokonzerwa neasina kuenzana, uye saizi yemapupu inotaridza kuwanda kwekupfeka.Iyo fluidity yekunamatira inongotarisa nguva yainotora kuzadza mapundu, kwete dhigirii.Mune mamwe mazwi, kunyange kana iyo yakanamatira ine mvura yakanaka, kana iyo yekuvhara yakawanda yakaderera, pachange paine zviitiko zvakadai se "mavara machena, mabhubhu".
3.2Kupfeka chimiro
Mamiriro ekuputira anotaridzirwa nekugoverwa kwekunamatira kunotamiswa nemucheka wekuvhara net roller kune substrate.Nokudaro, pasi pehuwandu hwekuputira humwechete, hutete hwemesh rusvingo rwekuputira roller, kupfupika kwekufamba pakati pezvinyorwa zvekunamatira mushure mekutamiswa, kukurumidza kuumbwa kwekunamatira, uye zviri nani kuonekwa.Sesimba rekunze rinokanganisa kubatanidzwa kwekunamatira, kushandiswa kweyunifomu glue rollers kune zvakakosha zvakanyanya kunaka pakuonekwa kwemubatanidzwa pane izvo zvisina kushandiswa.
3.3Condition
Kupisa kwakasiyana-siyana kunosarudza yekutanga viscosity yekunamatira panguva yekugadzira, uye yekutanga viscosity inosarudza kuyerera kwekutanga.Iyo yakakwirira tembiricha, yakaderera iyo viscosity yekunamatira, uye zviri nani kuyerera.Nekudaro, sezvo iyo solvent inokurumidza kukurumidza, iyo yekusangana kweiyo inoshanda mhinduro inoshanduka nekukurumidza.Nokudaro, pasi pemamiriro ekushisa, iyo solvent evaporation rate inopindirana kune viscosity yekushanda kwekugadzirisa.Mukugadzira zvakawandisa, kudzora mwero wekunyungudika kwenyungudika yave nyaya yakakosha.Humidity iri munharaunda inomhanyisa kukurumidza kuita kweadhesive, ichiwedzera kuwedzera kwe viscosity yekunamatira.
4. Mhedziso
Mukuita kwekugadzira, kunzwisiswa kwakajeka kwekuita, kuwirirana, uye basa re "adhesive leveling" pamatanho akasiyana anogona kutibatsira kuona chikonzero chechokwadi chekuonekwa kwezvinetso muzvinhu zvinoumbwa, uye nekukurumidza kuona zviratidzo zvedambudziko nekuzvigadzirisa. .
