Abstract:Chinyorwa ichi chinonyanya kusuma mapoinzi ekugadzirisa-isina kompositi inosanganisirwa,kusanganisira,tembiricha yekudzora,kuvharidzira huwandu hwekudzora,tension control,kumanikidza kutonga,inki uye glue kuenzanisa, kutonga humidity nenzvimbo yayo, glue preheating, nezvimwe.
Solvent yemahara macomposites ari kuwedzera kushandiswa, uye maitiro ekushandisa zvakanaka maitiro aya inyaya ine hanya nemunhu wese.Kuti ushandise zvakanaka zvinonyungudutsa-isina kompositi, munyori anokurudzira zvakasimba kuti mabhizinesi ane mamiriro ashandise akawanda-isina solvent-isina kana kaviri glue cylinders, ndiko kuti, shandisa glue cylinders, imwe ine universal adhesive inovhara yakawanda yechigadzirwa chimiro, uye imwe yacho ichisarudza chinonamira chinoshanda chakakodzera pamusoro kana yemukati dhizaini sekuwedzera zvichienderana neyakagadzirwa chigadzirwa chemutengi.
Mabhenefiti ekushandisa kaviri rubber cylinder ndeaya: anogona kuwedzera huwandu hwemashandisirwo emakompositi asina solvent, kuderedza kuburitswa, kuve nemutengo wakaderera, uye kugona kwakanyanya.Uye hapana chikonzero chekugara uchichenesa silinda yeglue, shandura zvinonamira, uye kuderedza tsvina.Iwe unogona zvakare kusarudza anonamira zvichienderana nechigadzirwa uye zvinodiwa nevatengi kuti uve nechokwadi chemhando yechigadzirwa.
Mukuita kwenguva refu yebasa revatengi, ini zvakare ndakapfupisa mamwe maitiro ekudzora mapoinzi anofanirwa kutariswa kuitira kuti uite basa rakanaka musolvent-isina komputa.
1.Kuchena
Kuti uwane yakanaka yakanyungudika-isina composite, chinhu chekutanga kuita kuve wakachena, inova zvakare poindi inoregedzerwa nyore nyore nemabhizinesi.
Iyo yakagadzika yakaomesesa roller, kuyera yakasimba roller, coating roller, coating pressure roller, composite rigid roller, kusanganisa gidhi chubhu, main uye kurapa agent mbiya yemuchina wekusanganisa, pamwe neakasiyana gidhi roller, inofanirwa kuve yakachena uye isina zvinhu zvekunze, nekuti chero chinhu chekunze munzvimbo idzi chinokonzeresa mabubbles uye mavara machena pamusoro peiyo composite firimu.
2.Temperature control
Chinhu chikuru chekunamatira-isina kunamatira iNCO, nepo mumiririri ari OH.Iyo density, viscosity, kuita kweiyo huru uye yekurapa vamiririri, pamwe nezvinhu zvakaita sehupenyu hwesevhisi, tembiricha, tembiricha yekurapa, uye nguva yekunamatira, zvese zvinogona kukanganisa kunaka kweiyo composite.
Solvent yemahara polyurethane adhesive ine yakakwira viscosity pakamuri tembiricha nekuda kwekushaikwa kwemamorekuru madiki anonyungudutsa, akakwira intermolecular masimba, uye kuumbwa kwehydrogen bond.Kupisa kunogona kunyatso kudzikisa viscosity, asi yakanyanya kupisa tembiricha inogona kutungamira nyore kune gelation, ichigadzira yakakwira molecular uremu resins, zvichiita kuti kukoira kuome kana kusaenzana.Nokudaro, kudzora kupisa kwekuputira kwakakosha zvikuru.
Kazhinji, vatengesi vanonamatira vanopa vatengi mamwe maparamendi ekushandisa sereferensi, uye tembiricha yekushandiswa inowanzopihwa seyero kukosha.
Iyo yakakwirira tembiricha isati yasanganiswa, iyo yakaderera iyo viscosity;iyo yakakwirira yekushisa mushure mekusanganiswa, iyo yakakwirira ye viscosity.
Kugadziriswa kwekushisa kwekuyeresa roller uye coating roller kunonyanya kuenderana neiyo viscosity yekunamatira.Iyo yakakwirira viscosity yekunamatira, iyo yakakwirira tembiricha yekuyera roller.Tembiricha yeanosanganiswa roller inogona kazhinji kudzorwa pa50 ± 5 ° C.
3.Glue huwandu hwekutonga
Zvinoenderana neakasiyana akaumbwa zvinhu, huwandu hwakasiyana hweglue hunogona kushandiswa.Sezvinoratidzwa mutafura, huwandu hwehuwandu hweglue hunopihwa, uye kutonga kweglue huwandu mukugadzirwa kunonyanya kutariswa negap uye kukurumidza chiyero pakati pekuyera roller uye yakagadziriswa roller.Glue application yemari
4.pressure control
Pamusana pekuti iyo yekuputira roller inodzora huwandu hweglue inoshandiswa negap uye chiyero chekukurumidza pakati pemavhiri maviri emwenje, saizi yekumanikidza yekuputira ichakanganisa zvakananga huwandu hweglue yakaiswa.Iyo yakakwirira yekumanikidza, iyo idiki iyo yakawanda yeglue yakaiswa.
5.Kuenderana pakati peinki uye glue
Iko kuenderana pakati pezvinonyungudutsa-isina adhesives neingi kazhinji kwakanaka mazuvano.Nekudaro, kana makambani achinja vanogadzira ingi kana masisitimu ekunamira, ivo vachiri kuda kuitisa bvunzo dzekuenderana.
6.Tension control
Kudzora tension kwakakosha musolvent-isina composite nekuti kunamatira kwayo kwekutanga kwakadzikira.Kana kukakavara kwepamberi uye kumashure membrane hakuenderane, pane mukana wekuti panguva yekukura, shrinkage ye membrane inogona kunge yakasiyana, zvichiita kuti pave nekuonekwa kwemabhuru uye tunnels.
Kazhinji, kudya kwechipiri kunofanira kuderedzwa zvakanyanya sezvinobvira, uye kune mafirimu akareba, kushushikana uye kutonhora kwekombikiti roller kunofanira kuwedzerwa zvakakodzera.Edza kudzivirira kupeta kweiyo composite firimu zvakanyanya sezvinobvira.
7.Control humidity uye nzvimbo yaro
Gara uchitarisa shanduko muhumidity uye gadzirisa chiyero cheiyo main agent uye anorapa agent zvinoenderana.Nekuda kwekukurumidza kukurumidza kwemusanganiswa-isina musanganiswa, kana hunyoro hwakanyanya, firimu rinoumbwa rakaputirwa neglue richaramba richisangana nehunyoro hwemumhepo, richidya imwe NCO, zvichikonzera zviitiko zvakaita seglue kusaoma uye kushomeka. peeling.
Nekuda kwekumhanya kwakanyanya kwemashini yekunyungudutsa-isina laminating, iyo substrate inoshandiswa ichagadzira static magetsi, zvichiita kuti iyo inodhinda firimu itore nyore guruva uye tsvina, inokanganisa kutaridzika kwechigadzirwa.Nokudaro, nzvimbo yekushanda yekugadzira inofanira kunge yakavharwa, kuchengetedza musangano mukati mehutano hunodiwa uye hunyoro.
8.Glue preheating
Kazhinji, glue risati rapinda mucylinder rinoda kufanopisa, uye glue rakasanganiswa rinogona kushandiswa chete mushure mekupisa kune imwe tembiricha kuti ive nechokwadi chekufambisa kweglue.
9. Mhedziso
Muchikamu chazvino umo musanganiswa-isina musanganiswa uye yakaoma composite inowirirana, mabhizinesi anofanirwa kuwedzera mashandisirwo emidziyo uye purofiti.Iyo nzira inogona kuve yakanyungudika-isina composite, uye haizombove yakaoma composite.Zvinonzwisisika uye zvinobudirira kuronga kugadzirwa, uye shandisa zvinobudirira midziyo iripo.Nekudzora maitiro uye kumisikidza echokwadi manyorerwo ekushandisa, kurasikirwa kusiri madikanwa kwekugadzira kunogona kudzikiswa.
