Nzira Yokusanganisa Solvent-Yemahara Adhesives?

Ikozvino pane maviri marudzi e-solvent-yemahara anonamatira ekushanduka ekupakira makomputa, imwe uye zvakapetwa zvikamu. Chinhu chimwe chete chinonyanya kushandiswa pabepa uye zvisina kusukwa, izvo zvinogona kushanda pasina kusanganisa uye pasina kugadzirisa chiyero. Dual zvinoriumba zvinogona kushandiswa kune akasiyana anochinjika ekuputira firimu. Zvichienderana nezvakaitika pauri, peji rino rinotsanangura maitiro ekuchinja chiyero chezvinhu zviviri nenzira dzakasiyana uye nemashandiro azvinoita.

Chekutanga, iyo inosanganisa chiyero chirevo cheye solvent-yemahara yakasungwa yakasungwa yakagadzirirwa.

Pane zvinhu zvitatu kumusanganiswa reshiyo dhizaini yekusanganisa-isina laminating yekunamatira.

1. Edza kuenzanisa musanganiswa reshiyo yezvikamu zveA & B kusvika pahuremu.

A / B 's compacting blending ratio ine mukana wekuve wehuremu hwakaenzana. Semuenzaniso, X i100A yakasanganiswa ne90B, Y iri 100A uye 50B. 1% shanduko yeB inounza 1.1% uremu shanduko yeA chikamu che X uye 2% ya Y. Kazhinji, 2% shanduko muyero yekusanganisa inogamuchirwa panguva yekugadzirwa, zvichikonzera kushanduka kwehuremu hwe 2. 2 % uye4%. Kana huremu hwavo hwakasiyana zvakanyanya, izvi zvinogona kutungamira kune anotevera anomalies:

(1) A / B zvinhu zvakaoma kusanganisa mushe zvekuti musanganiswa hauna kunyorova.

(2) Nekuda kwekushayikwa kwechikamu B, kumanikidzwa kwemusanganisi kwakanyanya kwazvo kuti kuve nechokwadi chekuyerera, izvo zvinoita kuti kutsauka kwezvinamatira uye kuderera kwekugadzirwa.

2.Ipedyo sezvinobvira kune viscosity yezvinhu zveA & B

Iyo yakaderera iyo viscosity yechikamu A & B pane yakakodzera tembiricha, zvirinani iyo yekusanganisa mhedzisiro. Tichifunga nezve zvinoitwa bhainda, iyo yekutanga viscosity yezvinhu zviri zviviri yakatosiyana. Kupisa kunofanirwa kudzorwa zvakasiyana kuti kuchinje kukosha kweiyo viscous. Kuwedzera tembiricha yechikamu chepakutanga neakanyanya viscosity kunoita kuti ive padhuze nechimwe chikamu, uye inobatsira kune ese ari musanganisi metering mudziyo uye pombi yekubuda.

3. Kuwedzera kushivirira kweA & B musanganiswa

Nekuda kwezvimwe zvinhu zvekunze mukumesa, panofanirwa kuve nekumwe kutsauka mukusanganisa ratio. Kuwedzera kushivirira kweA / B kusanganiswa kwemasanganiswa ratio kunogona kunyatso kuripa zvakashata zvekutsauka uku. Semuenzaniso, iyo yakajairika solvent yemahara inonamira WD8118A / B yezvinhu zvitsva zvinhu zvinomira kubva zvakajairika musanganiswa we100: 75 kune musanganiswa we100: 60 - 85, ese ari maviri anogamuchirwa mukushandiswa uye anotambirwa zvakanaka nevatengi vazhinji.

Kechipiri, musimboti uye nzira yekusanganisa reshiyo yekugadzirisa

(1) Rakagadziridzwa kuti ambient tembiricha uye mwando

Kazhinji, zvirimo zveNCO muchikamu A zvakakwirira, nepo maitiro nemhepo uye mweya mufirimu uri kuruboshwe. Nekudaro, mukati memwedzi yezhizha, kana paine mweya wakawanda mudenga uye iyo firimu ine hunyoro hwakanyanya, chinhu cheA chinofanira kuwedzerwa kuti chipise hutsi hwakawandisa, izvo zvinoita kuti zviitwe nenzira yakakodzera yekunamatira.

(2) Yakagadziriswa inki zvinhu uye zvakasara zvakasara

Yakawanda inogadziriswa kurongedza yakadhindwa firimu, yekumba yekudhinda maitiro ndeyeye solvent ink gravure kudhinda. Mune solvent-based inks sechiwedzero pachave neinodzora uye yekudzosera, ese ari polyurethane resin system, mune yekunamatira neNCO reaction inogona kudya imwe NCO.

Isu tine hanya nehutsanana nehunyoro hweakasara solvent. Ivo vacharamba vakawedzera kana kushoma pane zvakadhindwa, uye iyo yakasara inoshanda hydrogen ichadya imwe NCO. Kana matete uye matete akasara akakwirira, tinogona kuwedzera chinhu A kuvandudza mhedzisiro.

(3) Yakagadziriswa yealuminium kuchinjisa

Zvakawanda zvinogadziriswa zvekutakura zvinhu izvozvi zvakavhenekerwa, uye mhedzisiro yekushushikana pane kupfeka inogona kuderedzwa nekugadzirisa muyero wekusanganisa wezvinhu zveA / B kuti zvinyorovese, zvichinyanya kuwedzera chikamu cheB nenzira kwayo uye nekudzikisa mamiriro ekuchinjisa ealuminium kuburikidza nekukanganisa zvinonamatira. .
