Pari zvino kune mhando mbiri dzezvinonamira zvisina solvent zvezvinobatanidza zvinochinjika, zvikamu zvega zvega uye zvikamu zvekaviri. Chikamu chimwe chete chinoshandiswa zvakanyanya pamapepa neasina kurukwa, izvo zvinogona kushandiswa pasina kusanganisa uye pasina kugadzirisa chiyero. Zvikamu zviviri zvinogona kushandiswa kune akasiyana-siyana mafirimi ekurongedza anochinjika. Zvichibva pane zvakaitika kwauri, peji rino richatsanangura maitiro ekuchinja chiyero chezvikamu zviviri nekuda kwezvinangwa zvakasiyana uye mashandiro azvo.
Chekutanga, nheyo yekusanganisa chiyero chezvisungo zve laminated binders zvisina solvent yakagadzirwa.
Pane zvinhu zvitatu zvinoumba dhizaini yehuwandu hwemusanganiswa wechinamatidziro chisina solvent laminating:
1. Edza kuenzanisa chiyero chemusanganiswa wezvikamu zveA neB nehuremu.
Chiyero chekusanganisa cheA / B chine mukana wekuva nehuremu hwakaenzana. Semuenzaniso, X i100A yakasanganiswa ne90B, Y i100A uye 50B. Kuchinja kwe1% kweB kuchaita kuti pave nekuchinja kwehuremu kwe1.1% kwechikamu cheA cheX ne2% yeY. Kazhinji, kuchinja kwe2% muchiyero chekusanganisa kunogamuchirwa panguva yekugadzira, zvichikonzera kuchinja kwehuremu kwe2.2% ne4%. Kana huremu hwavo hwakasiyana zvakanyanya, izvi zvinogona kutungamira kune zvinotevera:
(1) Zvikamu zveA / B zvakaoma kusanganisa zvakanaka zvekuti musanganiswa wacho hauna kunyorova zvakakwana.
(2) Nekuda kwekushaikwa kwechikamu B, kumanikidzwa kwechisanganiswa kwakaderera zvakanyanya kuti chive nechokwadi chekuti zvinonamira zvinoyerera nguva dzose, izvo zvinoita kuti manamatisi atsauke uye kugadzirwa kuderera.
2. Zviri pedyo nekunaka kwezvikamu zveA & B
Kana viscosity yechikamu A & B yakaderera patembiricha yakakodzera, zvinoita kuti kusanganisa kuve nani. Tichifunga nezvekushanda kwebinder, viscosity yekutanga yezvikamu zvese zvakasiyana zvachose. Tembiricha inofanira kudzorwa yoga kuti igadzirise viscosity. Kuwedzera tembiricha yechikamu chekutanga nekusimba kwakanyanya kunoita kuti chive pedyo nechimwe chikamu, uye zvinobatsira kune zvese mudziyo wekusanganisa metering uye pombi inobuda.
3. Kuwedzera kushivirira kwemusanganiswa weA neB
Nekuda kwezvimwe zvinhu zvekunze mukunamira, panofanira kunge paine kutsauka muhuwandu hwekusanganisa. Kuwedzera kushivirira kwehuwandu hwekusanganiswa kweA / B kunogona kutsiva zvinobudirira mhedzisiro yakaipa yekutsauka uku. Semuenzaniso, glue yakajairika isina solvent WD8118A / B yezvinhu zvitsva inotangira pamusanganiswa wakajairika we100: 75 kusvika pamusanganiswa we100: 60 - 85, zvese zviri zviviri zvinogamuchirwa mukushandiswa uye zvinogamuchirwa zvakanaka nevatengi vazhinji.
Chechipiri, musimboti uye nzira yekusanganisa chiyero chekugadzirisa
(1) Yakagadziridzwa kuti ikwane tembiricha yekunze uye hunyoro
Kazhinji, huwandu hweNCO muchikamu A hwakakwira, nepo huwandu hwemhepo nemweya uri mufirimu huri kuruboshwe. Zvisinei, mumwedzi yezhizha, kana paine utsi hwakawanda mumhepo uye firimu rine hunyoro hwakawanda, chikamu A chinofanira kuwedzerwa kuti chishandise utsi hwakawandisa, izvo zvichaita kuti kunamira kuve nyore.
(2) Yakagadziridzwa kuti ishandiswe neingi nezvinhu zvinonyungudutsa
Kurongedza kwakawanda kunochinjika ifirimu rakadhindwa, nzira yekudhinda yemumba inodhindwa neinki inonyungudutsa gravure. Muinki dzine solvent-based sekuwedzera, pachava nemusanganiswa uye mudzoreredzi, ese ari maviri ari polyurethane resin system, uye mune glue ine NCO reaction inogona kushandisa NCO.
Tine hanya nekuchena uye hunyoro hwechinhu chinosara. Zvicharamba zviri padhinda, uye hydrogen inoshanda yasara ichadya NCO imwe. Kana zvisaririra zvakatetepa uye zvinodzora zvakakwira, tinogona kuwedzera chikamu A kuti tivandudze mhedzisiro.
(3) Yakagadziridzwa kuti ishandiswe nearuminiyamu
Zvinhu zvakawanda zvekurongedza zvinochinjika zvava nealuminium, uye mhedzisiro yekushushikana pajira inogona kuderedzwa nekugadzirisa chiyero chekusanganisa chezvikamu zveA / B kuti zvinyorove, kazhinji kuwedzera chikamu cheB zvakakodzera uye kuderedza kutamiswa kwearuminiyamu kuburikidza nezvinonamira zvinopindira.
