Pfupiso: Chinyorwa ichi chinoongorora zvakadzama nezvehunhu hwechinonamira pakukwiza simbi. Pamusoro peizvi, chinotaura kuti pachinzvimbo chekutonga mashandiro ekukwiza simbi nekutarisa kana paine'mavanga machena' kana 'mabhuru', kujeka kwezvinhu zvakagadzirwa nelaminate ndiko kunogona kuva chiyero chekuongorora mashandiro ekunamira.
1. Dambudziko reMabhuru uye Kuenzana kweGlue
Mavara machena, mabubbles, uye kusajeka zvakanaka ndizvo zvinhu zvinowanzoonekwa pakugadzirwa kwezvinhu zvakasanganiswa. Kazhinji, vagadziri vezvinhu zvakasanganiswa vanoti zvinhu zviri pamusoro apa zvinokonzerwa nekusagadzikana kweglue!
1.1 Guruu iri harisi guruu iroro
Vagadziri vezvinhu zvakagadzirwa necomposite vanogona kudzorera mabara asina kuvhurwa uye asina kushandiswa eglue kune vatengesi zvichibva pakuona kwekusagadzikana kweglue, kana kuendesa zvichemo kana zvikumbiro kune vatengesi.
Zvinofanira kucherechedzwa kuti guruu rinoonekwa serisina simba rakawanda rekuenzanisa i "mhinduro inoshanda neguruu" yakagadzirwa/yakasanganiswa nevatengi uye ine viscosity yemutengo chaiwo. Guruu rinodzoserwa ndiro bhaketi rekutanga reguruu risina kuvhurwa.
Mabhaketi maviri aya e "glue" ipfungwa dzakasiyana zvachose!
1.2 Zviratidzo zvekuongorora glue leveling
Zviratidzo zvehunyanzvi zvekuongorora mashandiro ekunamira zvinofanira kunge zviri kusimba uye kusimba kwekunyorova pamusoro. Kana kuti, "kunyorova kweglue" musanganiswa we "kunyorova kweglue" uye "kunyorova kweglue".
Pakupisa kwemukamuri, kunyorova kwemvura pamusoro pe ethyl acetate kunosvika 26mN/m.
Kuwanda kwepakutanga kwezvinonamira zve polyurethane zvine solvent zvinoshandiswa mukugadzira zvinhu zvine composite kunowanzova pakati pe50% -80%. Zvisati zvatanga kugadzira zvinonamira, zvinonamira zvataurwa pamusoro apa zvinofanirwa kuderedzwa kusvika pakushanda kwehuwandu hunosvika 20% -45%.
Nekuda kwekuti chinhu chikuru chiri mu diluted adhesive working solution iethyl acetate, surface wetting tension ye diluted adhesive working solution ichave pedyo ne surface wetting tension ye ethyl acetate pachayo.
Saka, chero bedzi kunyorova kwepamusoro pechinhu chinoshandiswa kuchizadzisa zvinodiwa zvekugadzirisa zvinhu zvakasanganiswa, kunyorova kwechinamira kuchava kwakanaka!
Kuongororwa kwekuyerera kweglue ndiko kupenya. Muchikamu chekugadzirisa zvinhu zvakasanganiswa, chinonzi kupenya (kureva kupenya kwekushanda) zvinoreva nguva mumasekonzi iyo glue inoshanda inosangana nemvura painobuda mukapu yekupenya, inoyerwa uchishandisa muenzaniso chaiwo wekapu yekupenya. Zvinogona kutariswa kuti mvura inoshanda yeglue yakagadzirwa kubva mumhando dzakasiyana dzeglue yebhaketi yekutanga ine "kupenya kwekushanda" kwakafanana, uye "mvura inoshanda" yayo ine "kupenya kweglue" kwakafanana!
Mune mamwe mamiriro asina kuchinja, kana "kunaka kwekushanda" kwe "kushanda kwemvura" yakagadzirwa ne "furemu imwe chete" yakabatana, "kunaka kwemvura" kwayo kuri nani!
Zvikurukuru, kune akasiyana magiredhi ekunamatira, kana kukosha kwekunaka kwemhinduro inoshanda yakaderedzwa iri masekondi gumi nemashanu, saka mhinduro inoshanda yakagadzirwa nemagiredhi aya ekunamatira ine "glue leveling" yakafanana.
1.3 Hunhu hwekuenzana kweglue hunhu hwemvura inoshanda neglue
Mamwe maalcohols haaite mvura inonamira kana bharero ravhurwa, asi anoumba jelly yakaita se projectile isina kuyerera. Anofanira kunyungudutswa uye kusanganiswa nehuwandu hwakakodzera hwe organic solvent kuti awane huwandu hwaunoda uye kusimba kweglue.
Zviri pachena kuti kushanda kweglue pakuyera kuenzanisa iongororo yemhinduro yekushanda yakagadzirwa kuita "huwandu hwekushanda" hwakati, pane kuongororwa kweglue yepakutanga isina kusanganiswa.
Saka, hazvina kururama kutaura kuti glue iri kukonzerwa nehunhu hwakajairika hweglue rebhaketi remhando imwe chete!
2. Zvinhu zvinokanganisa kuenzana kwenamira
Zvisinei, kune musiyano mukuru pahuwandu hwemvura inonamira yakasanganiswa!
Sezvambotaurwa, zviratidzo zvikuru zvekuongorora mashandiro emvura inoshanda ine adhesive nderekunyorovesa pamusoro uye kunyorovesa kwekushanda. Chiratidzo chekunyorovesa pamusoro hachiratidzi shanduko huru mukati mehuwandu hwenguva dzose hwekushanda. Saka, chinangwa chekunyorovesa kwakashata ndechekuti panguva yekushandiswa, kunyorovesa kweadhesive kunowedzera zvisingawanzoitiki nekuda kwezvimwe zvinhu, zvichikonzera kudzikira kwekushanda kwayo!
Ndezvipi zvinhu zvinogona kukonzera shanduko mukunaka kweglue panguva yekushandiswa kwayo?
Pane zvinhu zviviri zvikuru zvinogona kukonzera shanduko mukunaka kweglue, chimwe ikupisa kweglue, asi kuwanda kweglue.
Mumamiriro ezvinhu akajairwa, viscosity yemvura inoderera nekupisa kuri kuwedzera.
Pamabhuku ekushandisa anopiwa nemakambani akasiyana-siyana ekunamira, huwandu hwe viscosity yemhinduro yekunamira (isati yasanganiswa uye yapera) yakayerwa uchishandisa rotary viscometer kana viscosity cup patembiricha yemvura ye20 ° C kana 25 ° C (kureva tembiricha yemhinduro yekunamira pachayo) inowanzo ratidzwa.
Kudivi remutengi, kana tembiricha yekuchengetera bhaketi rekutanga reglue nemusanganiswa (ethyl acetate) yakakwira kana kudzika kupfuura 20 ° C kana 25 ° C, tembiricha yeglue yakagadzirwa ichavewo yakakwira kana kudzika kupfuura 20 ° C kana 25 ° C. Zviri pachena kuti kukosha kwe viscosity kweglue yakagadzirwa kuchavewo kwakaderera pane kukosha kwe viscosity kwakaratidzwa mubhuku rekushandisa. Munguva yechando, tembiricha yeglue yakagadzirwa inogona kunge yakaderera pane 5 ° C, uye muzhizha, tembiricha yeglue yakagadzirwa inogona kunge yakakwirira kupfuura 30 ° C!
Zvinofanira kucherechedzwa kuti ethyl acetate chinhu chinonyungudutsa zvakanyanya. Munguva yekushanduka kwe ethyl acetate, inotora kupisa kwakawanda kubva mumushonga unonamira uye mhepo yakapoteredza.
Parizvino, mayuniti mazhinji e laminating ari mumichina yakagadzirwa akavhurika uye ane michina yekubuda nayo, saka huwandu hwakawanda hwe solvent hunopera kubva pa glue disc ne barrel. Sekureva kwezvakacherechedzwa, mushure menguva yekushanda, tembiricha ye glue fluid iri mu glue tray dzimwe nguva inogona kunge yakaderera kupfuura 10 ° C pane tembiricha yekunze yakapoteredza!
Sezvo tembiricha yeglue ichidzikira zvishoma nezvishoma, viscosity yeglue ichawedzera zvishoma nezvishoma.
Saka, kushanda kweglue based solvent gluing kunoderera zvishoma nezvishoma nekuwedzera kwenguva yekushanda kwemuchina.
Nemamwe mashoko, kana uchida kuchengetedza kugadzikana kwekuenzanisa kweglue based solvent, unofanirwa kushandisa viscosity controller kana imwe nzira yakafanana kuchengetedza viscosity yeglue yakagadzikana mukati mekushandisa.
3. Zviratidzo zvekuongorora mhedzisiro chaiyo yekuenzanisa glue
Kuongororwa kwemhedzisiro yekuyera kweglue kunofanirwa kuve hunhu hwechigadzirwa chakabatanidzwa padanho rakati, uye mhedzisiro yekuyera kweglue inoreva mhedzisiro inowanikwa mushure mekunge glue yaiswa. Kungofanana ne "kumhanya kwakanyanya kwakagadzirwa" kwemotokari kuri hunhu hwechigadzirwa, kumhanya chaiko kwemotokari mumugwagwa mumamiriro ezvinhu chaiwo ndeimwe mhedzisiro.
Kuenzanisa glue zvakanaka ndicho chinhu chakakosha kuti uwane mhedzisiro yakanaka yekuenzana. Zvisinei, kushanda zvakanaka kweglue hakungangogumiri pamhedzisiro yakanaka yekuenzana kweglue, uye kunyangwe kana guruu riine kushanda kwakashata kwekuenzana (kureva kusimba kwakanyanya), mhedzisiro yakanaka yekuenzana kweglue inogona kuwanikwa mumamiriro ezvinhu chaiwo.
4. Hukama huripo pakati pemhedzisiro yekuenzana kweglue uye zviitiko zve "mavara machena" uye "mabhuru"
"Mavara machena, mabubbles, uye kujeka" zvisina kunaka ndizvo zvimwe zvinhu zvisingadiwi pazvigadzirwa zvakasanganiswa. Pane zvikonzero zvakawanda zvezvinetso zviri pamusoro apa, uye kusaenzana zvakanaka kweglue chimwe chazvo. Zvisinei, chikonzero chekusaenzana zvakanaka kweglue hachisi chete nekuda kwekusaenzana zvakanaka kweglue!
Kusawirirana zvakanaka kweglue hakungangoiti kuti pave ne "mavanga machena" kana "mabhuru", asi zvinogona kukanganisa kujeka kwefirimu recomposite. Kana kusawirirana kwakanyanya kwesubstrate yecomposite kwakashata, kunyangwe kana mhedzisiro yeglue iri yakanaka, pachine mukana wekuti pave ne "mavanga machena nemabhuru".
