Pfupiso: Chinyorwa chino chinonyanya kutaura nezvezvinhu zvinodzora zvinhu zvisina solvent, zvinosanganisira kudzora tembiricha, kudzora huwandu hwemachira, kudzora kumanikidzwa, kudzora kumanikidzwa, kufananidza inki neglue, kudzora hunyoro nenzvimbo yazvo, kupisa kweglue, nezvimwewo.
Zvinhu zvisina solvent zviri kushandiswa zvakanyanya, uye mashandisirwo akanaka emaitiro aya inyaya inonetsa munhu wese. Kuti vashandise zvakanaka zvinhu zvisina solvent, munyori anokurudzira zvakasimba kuti mabhizinesi ane mamiriro ezvinhu ashandise michina yakawanda isina solvent kana ma double glue cylinders, kureva kuti, shandisa ma glue cylinders maviri, rimwe rine glue rinofukidza chimiro chikuru chechigadzirwa, uye rimwe richisarudza glue inoshanda yakakodzera pamusoro kana mukati mechikamu sekuwedzera zvichibva pachimiro chechigadzirwa chemutengi.
Mabhenefiti ekushandisa silinda yerabha ine rabha mbiri ndeekuti: inogona kuwedzera huwandu hwezvinhu zvisinganyungudike, kuderedza utsi, kuva nemitengo yakaderera, uye kushanda zvakanaka. Uye hapana chikonzero chekuchenesa silinda yeglue nguva nenguva, kuchinjana manamira, uye kuderedza marara. Unogona zvakare kusarudza manamira zvichienderana nezvinodiwa nezvigadzirwa nevatengi kuti uve nechokwadi chekuti chigadzirwa chakanaka.
Mukushanda kwenguva refu kwekushandira vatengi, ndakapfupikisawo mamwe mapoinzi ekudzora maitiro anofanirwa kutariswa kuti tiite basa rakanaka mu composite isina solvent.
1. Kuchena
Kuti uwane musanganiswa wakanaka usina zvinonyungudutsa, chinhu chekutanga chekuita kuchena, inovawo pfungwa isingatariswe nyore nyore nemakambani.
Roller yakasimba yakagadziriswa, roller yakasimba yekuyera, roller yekufukidza, roller yekumanikidza yekufukidza, roller yakasimba yekusanganisa, chubhu yekutungamira yekusanganisa, bhareni guru uye rinogadzirisa remuchina wekusanganisa, pamwe nemaroller akasiyana-siyana ekutungamira, anofanira kunge akachena uye asina zvinhu zvekunze, nekuti chero chinhu chekunze munzvimbo idzi chinokonzera mabhuru nemavanga machena pamusoro pefirimu rekubatanidza.
2. Kudzora tembiricha
Chinhu chikuru chinonamira chisina solvent iNCO, nepo chinonamira chiri OH. Kuwanda, viscosity, mashandiro echinhu chikuru nechinonamira, pamwe nezvinhu zvakaita sehupenyu hwebasa, tembiricha, tembiricha yekupisa, uye nguva yechinamira, zvese zvinogona kukanganisa kunaka kwechinhu chakabatanidzwa.
Gundi repolyurethane risina solvent rine viscosity yakanyanya patembiricha yemumba nekuda kwekushaikwa kwemamorekuru madiki e solvent, masimba makuru epakati pemamorekuru, uye kuumbwa kwehydrogen bonds. Kupisa kunogona kuderedza viscosity zvinobudirira, asi tembiricha yakakwira zvakanyanya inogona kutungamira nyore nyore mu gelation, zvichigadzira mamorekuru ane huremu hwakawanda, zvichiita kuti coating ive yakaoma kana kuti isina kufanana. Naizvozvo, kudzora tembiricha ye coating kwakakosha zvikuru.
Kazhinji, vatengesi vezvinonamira vanopa vatengi mamwe maparameter ekushandisa sereferensi, uye tembiricha yekushandiswa inowanzo kupihwa sehuwandu hwenzvimbo.
Kana tembiricha yakakwira usati wasanganisa, viscosity yakaderera; kana tembiricha yakakwira mushure mekusanganisa, viscosity inowedzera.
Kugadziriswa kwetembiricha yeroller yekuyera neroller yekuputira kunonyanya kuenderana nekusimba kwenamira. Kusimba kwenamira kwakakwira, ndiko kusimba kweroller yekuyera kwakakwira. Tembiricha yeroller inosanganisa inogona kudzorwa pa50 ± 5 ° C.
3. Kudzora huwandu hweglue
Zvichienderana nezvinhu zvakasiyana-siyana zvakasanganiswa, huwandu hwakasiyana hweglue hunogona kushandiswa. Sezvakaratidzwa mutafura, huwandu hunofungidzirwa hweglue hunopihwa, uye kutonga kwehuwandu hweglue mukugadzirwa kunonyanya kutariswa nepakati uye chiyero chekumhanya pakati peroller yekuyera neroller yakagadzika.Huwandu hwekushandisa guruu
4.kudzora kumanikidzwa
Nekuda kwekuti chiputiriso chinomonera chinodzora huwandu hweglue rinoshandiswa nepakati uye chiyero chekumhanya pakati pemaroller maviri echiedza, saizi yekumanikidzwa kwekumonera inokanganisa zvakananga huwandu hweglue rinoshandiswa. Kana kumanikidzwa kwacho kwakakwira, huwandu hweglue rinoshandiswa hushoma.
5. Kuenderana kweinki neglue
Kuenderana pakati pezvinonamira zvisina solvent neinki kwagara kwakanaka mazuva ano. Zvisinei, kana makambani akachinja vagadziri veinki kana masisitimu ekunamira, achiri kufanira kuita bvunzo yekuenderana.
6. Kudzora kushushikana
Kudzora kushushikana kwakakosha zvikuru muzvinhu zvisina solvent nekuti kubatana kwayo kwekutanga kwakaderera. Kana kushushikana kwe membranes dzepamberi nedzekumashure kukasaenderana, pane mukana wekuti panguva yekukura, kuderera kwe membranes kunogona kusiyana, zvichikonzera kuoneka kwemabubbles nematunnels.
Kazhinji, kudya kwechipiri kunofanira kuderedzwa zvakanyanya sezvinobvira, uye kana paine mafirita akakora, kushushikana nekupisa kwemuchina wecomposite roller zvinofanira kuwedzerwa zvakakodzera. Edza kudzivirira kupeta firimu recomposite zvakanyanya sezvinobvira.
7.Dzora hunyoro nenzvimbo yahwo
Gara uchitarisa shanduko dzehunyoro uye gadzirisa chiyero chechinhu chikuru nechinoporesa zvinoenderana. Nekuda kwekumhanya kukuru kwechinhu chisina solvent-free composite, kana hunyoro hwacho hwakanyanya, firimu remusanganiswa rakaputirwa neglue richaramba richisangana nehunyoro mumhepo, richidya imwe NCO, zvichikonzera zviitiko zvakaita seglue kusaoma uye kusabuda zvakanaka.
Nekuda kwekumhanya kwakanyanya kwemuchina we laminating usina solvent, substrate inoshandiswa ichagadzira magetsi asingachinji, zvichiita kuti firimu rekudhinda ritore guruva netsvina zviri nyore, zvichikanganisa chitarisiko chechigadzirwa. Nokudaro, nzvimbo yekushanda kwekugadzira inofanira kunge yakavharwa zvishoma, zvichiita kuti workshop igare mukati mekupisa nekunyorova kunodiwa.
8. Kudziisa neglue
Kazhinji, guruu risati rapinda musirindiri rinofanira kupiswa moto pachine nguva, uye guruu rakasanganiswa rinogona kungoshandiswa chete mushure mekupiswa kusvika patembiricha yakati kuti kuve nechokwadi chekuti guruu rinopfuudzwa nekukurumidza.
9. Mhedziso
Muchikamu chazvino apo zvinhu zvisina solvent-free composite uye zvinhu zvakaoma zvinogara pamwe chete, mabhizinesi anofanirwa kuwedzera mashandisirwo emidziyo uye purofiti. Maitiro acho anogona kunge asina solvent-free composite, uye haazombofi akaita sezvinhu zvakaoma. Ronga kugadzirwa zvine musoro uye zvinobudirira, uye shandisa michina iripo zvinobudirira. Nekudzora maitiro acho uye kugadzira mabhuku ekushandisa chaiwo, kurasikirwa kwekugadzira kusingakoshi kunogona kuderedzwa.
