Pfupiso: Pepa iri rinoongorora mashandisirwo nekuvandudzwa kwepombi yekudzivirira kupisa isina solvent, uye rinopa pfungwa huru dzekudzora maitiro, kusanganisira kuiswa uye kusimbiswa kwehuwandu hwekuputira, huwandu hwehunyoro hwenzvimbo, kuiswa kwema parameter ekushanda kwemidziyo, uye zvinodiwa zvezvinhu zvakagadziriswa, nezvimwewo.
Nzira yekupfungaira nekudzima tsvina yave iripo kwemakore mazhinji. MuChina, nekuda kwekuvandudzwa kwekunonoka kwezvinonamira zvisina solvent, zvinenge zvese zvaishandiswa kugadzira mapakeji ekubika anodziya zvakanyanya. Iye zvino, zvinonamira zvisina solvent zvave nemakore gumi zvichigadzirwa muChina, nekuvandudzwa kukuru mumidziyo, zvinhu zvakagadziriswa, vashandi, uye tekinoroji. Mumamiriro emitemo yenyika yekudzivirira zvakatipoteredza, makambani ekudhinda mavara akagadzira nzvimbo yakakura yekuvandudza zvinonamira zvisina solvent kuitira kuti vatsvage purofiti nekuvandudzwa, zvichikonzerwa nekuwedzera kugona kwekugadzira. Saka, kufukidzwa kwezvinonamira zvisina solvent kuri kuwedzera kukura, uye kupfungaira, sterilization, uye kurongedza ndezvimwe zvacho.
1. Pfungwa yekubika kubvisa tsvina uye kushandisa manamatisi asina solvent
Kubika sterilization inzira yekuvhara nekuuraya mabhakitiriya mumidziyo isingapindi mhepo nekushandisa kumanikidza nekudziisa. Panyaya yekushandiswa, kuputira nekupisa simbi pari zvino kwakakamurwa kuita mhando mbiri: mapurasitiki nealuminium-plastic structures. Mamiriro ekubika akakamurwa kuita mazinga maviri: kubika nekupisa kwakanyanya (kupfuura 100 degrees Celsius).° C kusvika 121° C) uye kubika pakupisa kwakanyanya (pamusoro pe121)° C kusvika 145° C). Zvinonama zvisina kunyungudutsa zvinogona kufukidza kupiswa kwemvura pa121° C uye pazasi.
Panyaya yezvigadzirwa zvinoshanda, regai ndikuudzei muchidimbu mamiriro ekushandiswa kwezvigadzirwa zvakasiyana zveKangda:
Chimiro chepurasitiki: WD8116 yakashandiswa zvakanyanya uye zvakura muNY/RCPP pa121° C;
Chimiro chepurasitiki chearuminiyamu: Kushandiswa kweWD8262 muAL/RCPP pa121° C yakurawo zvakanyanya.
Panguva imwe chete, pakubika nekushandisa aruminiyamu-purasitiki senzira yekuvhiya, kushanda kweWD8262 pakati nepakati (ethyl maltol) kwakanakawo.
2. Nzira Yekufambira Mberi Kwekubika Kwekupisa Kwakanyanya
Pamusoro pemagadzirirwo matatu nemana anozivikanwa, zvinhu zvikuru zvinoshandiswa ndiPET, AL, NY, uye RCPP. Zvisinei, zvimwe zvinhu zvakatanga kushandiswawo pakubika pamusika, zvakaita sepurasitiki yealuminium inopenya, firimu repolyethylene rinopisa zvakanyanya, nezvimwewo. Zvisinei, hazvina kushandiswa zvakanyanya kana kuti zvakawanda, uye hwaro hwekushandiswa kwazvo huchiri kuda kuongororwa kwenguva yakareba uye maitiro akawanda. Panyaya iyi, manamatisi asina solvent anogonawo kushandiswa, uye mhedzisiro chaiyo inogamuchirwawo kuti iongororwe uye iongororwe nemakambani ekudhinda mavara.
Pamusoro pezvo, manamatisi asina zvinonyungudutsa ari kuvandudzawo mashandiro awo maererano nekupisa kwekuvhiyiwa. Parizvino, kufambira mberi kukuru kwaitwa mukusimbisa mashandiro ezvigadzirwa zveKonda New Materials zvisina zvinonyungudutsa pasi pemamiriro e125.° C uye 128° C, uye kuedza kuri kuitwa kuti pave nekupisa kwakanyanya, zvakaita se135° Kubika C uye kunyange 145° Kubika.
3. Pfungwa huru dzekushandisa uye kutonga maitiro
3.1Kugadzika uye kusimbiswa kwehuwandu hwe namatidza
Mazuva ano, kufarirwa kwemidziyo isina solvent kuri kuwedzera, uye vagadziri vazhinji vakawana ruzivo rwakawanda neruzivo mukushandisa michina isina solvent. Zvisinei, maitiro ekubika ekupisa kwakanyanya achiri kuda huwandu hwakati hweglue inopindirana (kureva ukobvu), uye huwandu hweglue mumaitiro ese hahuna kukwana kusangana nezvinodiwa zvekubika. Naizvozvo, kana uchishandisa gundi isina solvent pakubika kwakabatana, huwandu hweglue hunofanira kuwedzerwa, nehuwandu hunokurudzirwa hwe1.8-2.5g/m².
3.2 Hunyoro hwenzvimbo
Mazuva ano, vagadziri vazhinji vari kutanga kuona uye kukoshesa kukanganisa kwezvinhu zvakatipoteredza pamhando yechigadzirwa. Mushure mekupihwa chitupa uye muchidimbu chezviitiko zvakawanda zvinoshanda, zvinokurudzirwa kudzora hunyoro hwezvakatipoteredza pakati pe40% ne70%. Kana hunyoro hwakanyanya, hunofanira kunyoroveswa, uye kana hunyoro hwakanyanya, hunofanira kubviswa hunyoro. Nekuti chikamu chemvura chiri munharaunda chinobatanidzwa mukuita kweglue isina solvent, Zvisinei, kutora chikamu kwakanyanya mumvura kunogona kuderedza huremu hweglue uye kukonzera mamwe maitiro ekunze, nokudaro zvichikanganisa mashandiro ekudzivirira kupisa kwakanyanya panguva yekubika. Saka, zvakakosha kugadzirisa magadzirirwo ezvikamu zveA/B zvishoma munzvimbo dzinopisa zvakanyanya uye hunyoro.
3.3 Magadzirirwo eparameter ekushanda kwemudziyo
Magadzirirwo eparameter anoiswa zvichienderana nemamodheru akasiyana emidziyo nemagadzirirwo; Magadzirirwo ekumanikidzwa uye kururama kwehuwandu hwekugovera zvese zvinhu zvine chekuita nekudzora nekusimbisa. Mwero wepamusoro we otomatiki, kunyatsojeka, uye kushanda zviri nyore kwemidziyo isina solvent ndizvo zvakanakira zvayo, asi zvinofukidzawo kukosha kwekungwarira uye kungwarira kuri shure kwayo. Tagara tichisimbisa kuti mashandiro ekugadzira asina solvent inzira inongwarira.
3.4 Zvinodiwa pakushandisa zvinhu zvisina kugadzirwa
Kusatsetseka kwakanaka, kunyorova pamusoro, kuderera kwehuwandu hwemvura, uye hunyoro hwakafanana hwezvinhu zvakachekwa zvakatetepa ndizvo zvinodiwa kuti zvipedziswe kubika zvinhu zvakasanganiswa.
- Zvakanakira zvemacomposites asina solvent
Parizvino, zvigadzirwa zvekubika nekuchenesa zvinopisa zvakanyanya muindasitiri zvinonyanya kushandisa manamatisi ane zvinonyungudutsa pakugadzira zvinhu zvakaoma. Zvichienzaniswa nezvinonyungudutsa zvakaoma, kushandisa zvigadzirwa zvekubika zvisina zvinonyungudutsa zvine mabhenefiti anotevera:
4.1zvakanakira kushanda zvakanaka
Chinhu chakanaka pakushandisa manamatisi asina solvent ndechekuwedzera kugona kwekugadzira. Sezvazvinozivikanwa, kushandisa tekinoroji yakaoma yecomposite kugadzira zvinhu zvekubika nekuuraya utachiona zvinopisa zvakanyanya kune kumhanya kwakaderera kwekugadzira, kazhinji kunosvika 100m/min. Mamwe mamiriro emidziyo uye kutonga kwekugadzira kwakanaka, uye kunogona kusvika 120-130m/min. Zvisinei, mamiriro acho haana kunaka, 80-90m/min chete kana kutodzikira. Kugona kwekutanga kwemanamatisi asina solvent nemidziyo yecomposite kuri nani pane kweyakaoma composite, uye kumhanya kwecomposite kunogona kusvika 200m/min.
4.2mukana wemutengo
Huwandu hweglue rinoshandiswa paglue yekubikisa yakagadzirwa ne solvent yakakura, inodzorwa pa 4.0g/m2² Kuruboshwe nekurudyi, muganho hausi pasi pe3.5g/m2²；Kunyangwe huwandu hweglue rinoshandiswa paglue rekubikisa risina solvent huri 2.5g/m² Kana tichienzanisa nenzira dzinoshandisa zvinonyungudutsa, inewo mukana wemutengo wakawanda nekuda kwekunamira kwayo kwakawanda.
4.3Zvakanakira kuchengetedzeka nekuchengetedzwa kwezvakatipoteredza
Pakushandisa guruu rekubikisa rine solvent rakagadzirwa nekupisa kwakanyanya, huwandu hwakawanda hwe ethyl acetate hunofanira kuwedzerwa kuti husanyungudike, izvo zvinokanganisa kuchengetedzwa kwezvakatipoteredza uye kuchengetedzeka kwemuchina wekugadzira. Rinowanzovawo nedambudziko rekusara kwakawanda kwe solvent. Uye manamatisi asina solvent haana hanya dzakadaro zvachose.
4.4Zvakanakira kuchengetedza simba
Chiyero chekuporesa chezvigadzirwa zvinonamira zvakagadzirwa ne solvent chakakwira, chiri pa50° C kana kupfuura; Nguva yekuibva inofanira kuva maawa makumi manomwe nemaviri kana kupfuura. Kumhanya kwekuita kweglue yekubika isina solvent kunokurumidza, uye kudiwa kwekupisa kwekupisa nenguva yekupisa kuchava kwakaderera. Kazhinji, kupisa kwekupisa kunenge 35° C~48° C, uye nguva yekupora ndeye maawa makumi maviri nemana kusvika makumi mana nemasere, izvo zvinogona kubatsira vatengi kupfupisa kutenderera.
5. Mhedziso
Muchidimbu, manamatisi asina zvinonyungudutsa, nekuda kwehunhu hwawo hwakasiyana, makambani ekudhinda mavara, makambani ekubatanidza, uye makambani ekugadzira michina yekubatanidza isina zvinonyungudutsa ave achishandira pamwe nekutsigirana kwemakore mazhinji, achipa ruzivo rwakakosha muminda yavo. Tinotenda kuti manamatisi asina zvinonyungudutsa ane mashandisirwo akasiyana-siyana mune ramangwana. Pfungwa yekuvandudza yeKangda New Materials ndeyekuti "tanga tichishanda nesimba kugadzira kukosha kwevatengi uye kuvafambisa". Tinovimba kuti zvigadzirwa zvedu zvekubika zvinopisa zvakanyanya zvinogona kubatsira makambani akawanda ekudhinda mavara kutsvaga minda mitsva yekushandisa isina zvinonyungudutsa.
