Abstract: Chinyorwa Chinoongorora mune zvemhando yepamusoro pesvedzero yeiyo nhanho yekunamatira mukuomeswa mune izvi, iyo inotaura kuti pane kutonga maitiro ekutonga nekutonga kana paine'White mavara'
1.The bubble dambudziko uye kuunganidzwa kweglue
Mavara machena, mabhuru, uye pachena transpency inowanzoonekwa nyaya dzakanaka mukugadziriswa kwezvinhu zvemhando. Muzhinji, mapurisa ekunyora anopa nyaya dziri pamusoro apa dzekuremerwa neyezvinamatiro!
1.1Ichi glue haisi iyo glue
Vagadziri vezvekunyama vanogona kudzosa madhiri asina kushandiswa uye vasingashandiswi vevatengesi zvichienderana nekutonga kwekutongwa kwekunamatira, kana kuti zvichemo zvemafaira kana zvevatengesi nevatengesi.
Izvo zvinofanirwa kucherechedzwa kuti glue yakafungidzirwa kuve nemarombo ekuremerwa kuita "Glue inoshanda mhinduro" iyo yakagadzirirwa / yakagadzirirwa nevatengi uye ine viscosity yakakosha. Iyo Glue yakadzoserwa ndiyo isina kubhadharwa bhakiti rekutanga reGlue.
Aya mabheji maviri e "Glue" akakwana pfungwa uye zvinhu!
1.2Ealuation zviratidzo zveGlue leveling
Iyo technical zviratidzo zvekuongorora mashandiro ekutambisa ekunamatira anofanira kunge ari viscosity uye nzvimbo yekunyorovesa. Kana kuti pane kuti, "Fluidity yeGlue" isanganiswa ye "Fluidity yeGlue" uye "kunyorova kweGlue".
Pamhepo tembiricha, iyo nzvimbo yekunyorovesa yekunetsana yeTetHyl acetate ndeye 26mn / m.
Iyo yekutanga mbiya yekuvhara (zvemukati zvemukati) yeSolvent based polyurethane anomiririra mumunda weComposite Kugadziriswa Kazhinji iri pakati pe50% -80%. Pamberi pekushandisa manyorerwo gadziriso, anomhanya-kutaurwa anoshongedza kuti anyaradzwe kune yakashanda yekushanda kwekutenderedza 20% -45%.
Nekuda kweizvozvo kuti chikamu chikuru mumudzimu yakasarudzika ndeye Ethyl acetate, iyo yekunyorovesa yekunetseka kwekushomeka kwekushanda kwekushanda kwekunyorova kwekunyorova kweTevyl acetate pachayo.
Naizvozvo, chero bedzi nzvimbo yekunyorovesa yekunyorovesa yeiyo substate yakashandiswa inosangana nezvinodiwa zvekugadzirisa, kunyorova kwekunamatira kuchave kwakanaka!
Kuongororwa kwehunhu hweglue ndeye viscosity. Mumunda wekuumbwa kweyakajaira, inonzi inonzi viscosity (kureva kuti inoshanda viscosity) inoreva nguva mumasekondi iri kuyerera kwemukombe weViscosity Zvinogona kutariswa kuti mvura yekushanda yeGlue yakagadzirirwa kubva kumakwenzi akasiyana ebakiti rekutanga Glue ane imwechete "kushanda", "kushanda kwemvura" kune zvakafanana "glue fluity"!
Pasi pemamwe mamiriro asina kuchinjika, iyo yakadzika iyo "yekushanda viscosity" yeiyo "yakashanda fluid" yakagadzirirwa nemhando imwe chete inonamatira, iri nani "inonamatira" inonamatira "!
Kunyanya, kwemakiromita akasiyana emitambo, kana iyo viscosity kukosha kwekugadzirisa kwekushanda kwemasekonzi gumi nemashanu, saka mhinduro yekushanda yakagadzirirwa nemavara aya emagetsi emagetsi "glue level".
1.3 iyo mwero midziyo ye glue hunhu hweglue inoshanda fluid
Dzimwe zvibiridzi hadziike viscous fluid kana mbiya ichangovhurwa, asi panzvimbo pejelly senge projectile isina fluidity. Ivo vanofanirwa kuve vanyungudutswa uye vakanyorerwa nehuwandu hwakakodzera hwe organic solvent kuti uwane iyo yaunoda kusunganidzwa uye viscosity yeglue.
Zviripachena kuti kuita kwekutambisa kweGlue kuongorora kwemhinduro yekushanda yakagadzirirwa kuve "kushanda kwekushanda", pane kuongororwa kweisina kuvharwa mbiya yepakutanga glue.
Naizvozvo, hazvina kunaka kufunga nezvekuremerwa kwakashata kwegwenzi kune chimwewo chimiro cheimwe mhando yeiyo yekutanga bhakiti glue!
2.Factors inokanganisa kuunganidzwa kwekuzvinamatira
Nekudaro, nekuda kwekunyanyisa kuomarara kushanda kwemhinduro, pane chokwadi mumugodhi wemvura yayo yekuzvinamatira!
Sezvambotaurwa, zviratidzo zvikuru zvekuongorora mashandiro ekutambisa ekunamatira kushanda kwemvura ndeyekunyorova kwemvura uye kushanda viscosity. Iyo chiratidzo chekunyoroveswa kwemvura kusagadzikana hakuratidze shanduko dzakakosha mukati meiyo nguva yekushanda pamwero wekushanda. Naizvozvo, kukosha kwekunetseka kwekunamatira ndiko kuti panguva yekunyora, iyo viscosity yekunamatira inowedzera nekuda kwezvimwe zvinhu, zvichikonzera kuderera kwekuita kwayo.
Ndezvipi zvinhu zvinogona kukonzera shanduko mune visikopa yeGlue panguva yayo yekunyorera?
Pane zvinhu zviviri zvikuru izvo zvinogona kukonzera shanduko mune zvevasangano weGlue, imwe tembiricha yeglue, asi kusvinura kweglue.
Mumamiriro ezvinhu akajairika, viscosity yemvura inoderera nekuwedzera kupisa.
Pamakambani evashandisi anopihwa nemakambani akasiyana ekuzvinamatira, iwo maVocossity solention soliture Solution pachayo) inowanzoratidzwa.
Padivi remutengi, kana tembiricha yekuchengetedza yeglue uye duliuent (etyl acetate) yakakwira kana yakaderera kupfuura makumi maviri. Kana 25 ° C. Natural, iyo chaiyo viscosity kukosha kweiyo glue yakagadzirirwa ichave yakaderera pane iyo viscosity kukosha kwakaratidzwa mubhuku racho. Munguva yechando, tembiricha yekunamatira gadziriro inogona kunge yakaderera pane 5 ° C, uye muzhizha, tembiricha yezvinetso yakagadzirirwa inogona kunge yakakwira kupfuura makumi matatu c!
Izvo zvinofanirwa kucherechedzwa kuti ethyl acetate inzvimbo yakaoma kwazvo yakajairika solvent. Munguva yeVolatlization Process yeTetHyl acetate, ichatora huwandu hukuru hwekupisa kubva kumhinduro yekuzvinamatira uye mweya wakapoteredzwa.
Parizvino, mauniti mazhinji ekurara mumachina akavhurika uye akashongedzerwa nemidziyo yemunharaunda yekupera kwemuno, saka huwandu hwakawanda hwekupaza hunobuda kubva muAdhesive disc uye mbiya. Sekureva kwekucherechedzwa, mushure menguva yekushanda, tembiricha yeglue inoshanda fluid muTray tray dzimwe nguva inogona kunge iri kupfuura gumi ° C yakaderera pane yakakomberedza tembiricha!
Sezvo tembiricha yegwenzi zvishoma nezvishoma inoderera, iwo wisikoka weglue uchawedzera zvishoma nezvishoma.
Saka, kuita kwekumisikidza kwekugadzirisa solvent anomhara zvishoma nezvishoma kunowedzera pamwe nehurongwa hwekushandisa kwemidziyo
Mune mamwe mazwi, kana iwe uchida kuchengetedza kugadzikana kwekusimbisa kwekushambadzira kwekunamatira, iwe unofanirwa kushandisa viscosity controller kana imwe nzira yakafanana yekuchengeta iyo yekunamatira visikoka yakamisikidzwa mumamiriro ekunyorera.
3.Evaluation zviratidzo zvechokwadi glue leveling mhinduro
Kuongororwa kwemhedzisiro yeglue kunofanirwa kunge kuri hunhu hwechigadzirwa chechigadzirwa pane imwe nhanho, uye mhedzisiro yeGlue inoreva kuti glue inoiswa.Kuita se "yakadzorerwa seyakagadzirwa" yemota iri Hunhu hwechigadzirwa, iyo chaiyo yekutyaira yekumhanyisa kwemotokari mumugwagwa uri mumamiriro ezvinhu mamwe mamiriro chimwe mhedzisiro.
Yakanaka glue leveling ndiyo yakakosha mamiriro ekuzadzisa yakanaka yekuwedzera mibairo. Nekudaro, kugona kwekuita kweGlue kungave kusakwana mune yakanaka glue migumisiro, uye kana iyo glue yakanyanya kuunganidzwa (kureva yakakwira viscosity), yakanaka glue leveling mhedzisiro inogona kuramba ichiwanikwa mumamiriro ezvinhu chaiwo.
4.kuenderana pakati pemhedzisiro yeglue kuyambuka uye zviitiko zve "White mavara" uye "Bubbles"
"Zvipfuyo Zvikomba, Bubbles, uye Transpency" zviitiko zvisingabvumirwe pane zvigadzirwa zvemavara. Pane zvikonzero zvakawanda zvezvinetso zviri pamusoro, uye kusarongeka kweglue ingori imwe yadzo. Nekudaro, chikonzero chekusanzwisisika chakasarudzika cheGlue hachisi chete chakakonzerwa nekumisikidzwa kweglue!
Mhedzisiro isina kunaka yeglue inogona kunge isiri kutungamira kune "chena mavara" kana "Bubbles", asi inogona kukanganisa transcency yefirimu remubatanidzwa. Kana iyo micro kumeso kweiyo substate is substrate iri murombo, kunyangwe kana mhedzisiro yekuzvinamatira kwakanaka, kuchine mukana we "mavara machena uye mabhuru".
