Parizvino pane marudzi maviri emhando dzekurimikira-dzemahara dzekuchinjika kwekuputika composites, zvikamu zviviri uye zviviri. Chikamu chimwe chete chinonyanya kushandiswa kune pepa uye nonwovens, izvo zvinogona kushanda pasina kusanganisa uye pasina kugadzirisa huwandu hweratio. Zvidimbu zviviri zvinogona kushandiswa kune akasiyana siyana ekuchinjika ekuputika pafirimu. Kubva pane zvakaitika kwauri, peji ino ichatsanangura nzira yekuchinja huwandu hwezvinhu zviviri zvikamu zviviri zvezvinangwa zvakasiyana uye kuti zvinoshanda sei.
Chekutanga, kusanganisa kwechiitiko chekusanganisa kweiyo solvent-isina lamarated mashura akagadzirwa.
Pane matatu ezvikamu kumishini yemusanganiswa kugadzirwa kwekugadziriswa kwemasimba-emahara anomarara:
1. Edza kufananidza iyo musanganiswa ratio yeA & B zvikamu kune uremu.
A / B 'S Compact kusanganisa chiyero chine mukana wekuve wekuve wechiyero chimwe chete. Semuenzaniso, X iri 100a yakasanganiswa ne 90b, y iri 100a uye 50b. 1% Shanduko yeB ichaitika mu 1.1% uremu shanduko yeiyo chikamu che x uye 2% yeY. % uye4%. Kana uremu hwavo hwakasiyana zvakanyanya, izvi zvinogona kutungamira kune anotevera anomalies:
(1.
.
2. Sezvo padyo sezvinobvira kune viscosity yeA & B zvikamu
Iyo yakadzika iyo viscosity yechikamu A & B pakudziya kwakakodzera, zvirinani kusanganisa. Kufunga nezve chiitiko cheBinder, iyo yekutanga viscosity yezvikamu zvese zviri zviviri zvakasiyana. Tembiricha inofanira kudzorwa zvakasiyana kuti igadzirise kukosha kweVisacous. Kuwedzera tembiricha yechikamu chepakutanga nekwakakwirira viscosity kunoita kuti iswedere kune imwe chikamu, uye inobatsira kune ese mutserendende mitezo yemumiriri uye pombi inobuda.
3. Kuwedzera kushivirira kweA & B musanganiswa
Nekuda kweimwe zvinhu zvekunze mukurasikirwa, panofanirwa kuve nekumwe kutsauka mukusanganisa ratio. Kuwedzera kushivirira kweA / B musanganiswa musanganiswa ratio inogona kubatsira zvinobudirira mhedzisiro yakaipa yekutsauka uku. Semuenzaniso, zvakajairika solvent yemahara adsive wd8118a / b yezvinhu zvitsva zvemukati kubva kune yakajairika yemabhuku 10: 70 kusvika musanganiswa wegumi: 60 - 85, ese ari maviri anogamuchirwa mukushandisa uye akagamuchirwa zvakanaka nevatengi vazhinji.
Kechipiri, nheyo uye nzira yekusanganisa kugadziriswa kwechiyero
(1) yakagadziridzwa kune ambient tembiricha uye humidity
Muzhinji, zvirimo zveNCCO mune chikamu chakakwira, apo maitiro nemhepo uye iyo muputi mufirimu iri kuruboshwe. Nekudaro, mukati memwedzi yezhizha, apo kune imwe steam mumhepo uye iyo firimu ine yakakwira zvinyorwa, chikamu chinofanira kuwedzerwa kuti uwedzere kupfeka, izvo zvinogonesa kuita kwakakodzera kwekunamatira.
(2) yakagadziridzwa yeInk zvinhu uye solvent zvakasara
Yakanyanya kuchinjika kurongedza inodhindwa firimu, maitiro ekudhinda ekudhinda ane solvent ink yekudhinda yekudhinda. MuSolvent-based inks sekuwedzera uko kuchave neDuliuent uye kudzoreredza, vese vari polyurethane resin system, mukunamatira neNCO maitiro anogona kudya imwe nco.
Isu tine hanya nekuchena uye zvinyoro-nyoro zvemukati zvakasara solvent. Ivo vanoramba vari zvakanyanya kana zvishoma pane kudhinda, uye vakasara vanoshingaira hydrogen ichapedza imwe NCO. Kana kutetepa uye kudzoreredza zvakasara zvakakwira, tinogona kuwedzera chikamu a kuti tivandudze zvawanikwa.
(3) yakagadziridzwa kuAluminium kutamisa
Zvizhinji zvinochinja zvekuputika zvinhu zvino zvave kuisirwa, uye mhedzisiro yekushushikana kwekubatanidza kunogona kuderedza huwandu hwekusanganisa, .
