Iyo nzira yekupisa uye sterilization yave iripo kwemakore mazhinji.MuChina, nekuda kwekunonoka kugadzirwa kweadhesive-isina-adhesives, anenge ese aishandiswa kuumba yakakwira-tembiricha yekubika kubika.Ikozvino, zvinonamira-zvisina zvinonyungudutsa zvakapfuura makore gumi ebudiriro muChina, nekuvandudzwa kwakakosha mumidziyo, zvigadzirwa, vashandi, uye tekinoroji.Mumamiriro ezvinhu emitemo yenyika yekuchengetedzwa kwemamiriro ekunze, mabhizinesi ekudhinda mavara akagadzira nzvimbo huru yekusimudzira yeadhesives-isina-solvent kuitira kutsvaga purofiti uye budiriro, inosundwa nechikonzero chekuwedzera simba rekugadzira. Naizvozvo, kufukidzwa kweanonyungudutsa asina adhesives ari kuwedzera kuwedzera. yakafara, uye inopisa, sterilization, uye kurongedza ndezvimwe zvacho.
1.Iyo pfungwa yekubika sterilization uye kushandiswa kwe-solvent-free adhesives
Kubika sterilization inzira yekuisa chisimbiso nekuuraya mabhakitiriya mumidziyo isina mhepo nekuisa kumanikidza uye kudziyisa.Panyaya yechimiro chekushandisa, steaming uye sterilization packaging parizvino yakakamurwa kuita marudzi maviri: epurasitiki nealuminium-plastiki zvimiro.Mamiriro ekubika akakamurwa kuita mazinga maviri: semi yakakwirira tembiricha yekubika (pamusoro pe100° C kusvika ku121° C) uye kupisa kwakanyanya kwekubika (kupfuura 121° C kusvika ku145° C).Solvent yemahara adhesive zvino inogona kuvhara kubika sterilization pa121° C uye pasi.
Panyaya yezvigadzirwa zvinoshanda, regai ndizivise muchidimbu mamiriro ekushandisa ezvakati wandei zvigadzirwa zveKangda:
Chimiro chepurasitiki: WD8116 yakashandiswa zvakanyanya uye yakakura muNY/RCPP pa121° C;
Aluminium plastiki chimiro:Kushandiswa kweWD8262 muAL/RCPP pa121° C zvakare akura chaizvo.
Panguva imwecheteyo, mukubika uye sterilization application yealuminium-plastiki chimiro, iyo yepakati (ethyl maltol) kushivirira kuita kweWD8262 zvakare yakanaka kwazvo.
2.The Future Development Direction of High Temperature Cooking
Kuwedzera kune akajairwa matatu - uye mana akaturikidzana zvimiro, zvinhu zvikuru zvinoshandiswa PET, AL, NY, uye RCPP.Zvisinei, zvimwe zvinhu zvakatanga kushandiswa pakubika zvigadzirwa pamusika, zvakadai sekupenya kwealuminium coating, high-temperature yekubika polyethylene film, etc. Zvisinei, hazvina kushandiswa pamwero mukuru kana muhuwandu, uye hwaro hwekushandisa kwavo kwakapararira kuchiri kudikanwa kuongororwa kwenguva yakareba uye mamwe maitiro.Musimboti, zvinonamira-zvisina solvent zvinogona kuiswa zvakare, uye mhedzisiro chaiyo inogamuchirwa kuti iongororwe uye kuongororwa nemabhizinesi ekudhinda mavara.
Pamusoro pezvo, zvinonamira-zvisina solvent zviri kuvandudza mashandiro avo maererano nekushisa kwe sterilization.Parizvino, kufambira mberi kwakakosha kwakaitwa mukusimbisa kwekuita kweKonda New Materials 'isina-solvent zvigadzirwa pasi pemamiriro e125.° C uye 128° C, uye kuedza kuri kuitwa kusvika pakakwirira tembiricha yekubikira, senge 135° C kubika uye kunyange 145° C kubika.
3.Key pfungwa dzekushandisa uye maitiro ekugadzirisa
3.1Kugadzika uye kusimbiswa kwehuwandu hwekunamatira
Mazuva ano, kufarirwa kwemidziyo isina-solvent kuri kuwedzera, uye vagadziri vazhinji vakawana ruzivo rwakawanda uye ruzivo rwekushandisa-isina solvent.Nekudaro, iyo yepamusoro-tembiricha yekubika sterillization process ichiri kuda imwe chiyero che interlayer adhesive (kureva ukobvu), uye huwandu hwekunamira mune zvakajairika maitiro hahukwani kuzadzisa zvinodiwa zvekubika sterilization.Naizvozvo, kana uchishandisa sosi isina-isina adhesive yekusanganisa kubika packaging, huwandu hwekunamira hwakaiswa hunofanira kuwedzerwa, nehuwandu hunokurudzirwa hwe1.8-2.5g/m.².
3.2 Humidity range yezvakatipoteredza
Mazuva ano, vagadziri vazhinji vari kutanga kuona uye kuisa kukosha kune kukanganisa kwezvakatipoteredza zvinhu pamhando yechigadzirwa.Mushure mekupa chitupa uye pfupiso yemakesi akawanda anoshanda, zvinokurudzirwa kudzora humidity kwezvakatipoteredza pakati pe40% ne70%.Kana hunyoro hwakanyanya kuderera, hunoda kuve hunyoro, uye kana hunyoro hwakanyanya, hunoda kuderedzwa.Nemhaka yokuti chikamu chemvura chiri mumhepo chinotora chikamu mukuita kweglue isina solvent, Zvisinei, kupindira kwemvura yakawandisa kunogona kuderedza huremu hwema molecular yeglue uye kukonzera mamwe maitiro emativi, nokudaro kukanganisa kushanda kwepamusoro-kupisa panguva yekubika.Naizvozvo, zvinodikanwa kugadzirisa magadzirirwo ezvikamu zveA / B zvishoma mukupisa kwakanyanya uye humidity nharaunda.
3.3 Parameter marongero ekushandisa mudziyo
Zvigadziriso zveParameter zvinoiswa zvinoenderana nemhando dzakasiyana dzemidziyo uye zvigadziriso;Iyo tension setting uye iko kurongeka kwereshiyo yekugovera zvese zvese zvekutonga nekusimbisa.Iyo yakakwira dhigirii ye otomatiki, kunyatsojeka, uye nyore kushanda kwemidziyo isina-solvent ndiyo yakanakira yayo, asi zvakare inovhara kukosha kwekungwarira uye kungwarira kuseri kwayo.Isu tagara tichisimbisa kuti solvent yemahara yekugadzira mashandiro inzira ine hunyanzvi.
3.4 Zvinodiwa zvekushandisa mbishi
Kudzikama kwakanaka, kunyorova kwepamusoro, shrinkage rate, uye kunyangwe hunyoro hwemufirimu mutete zvinhu zvakabikwa mamiriro anodiwa ekupedzisa kubika kwezvinhu zvinosanganiswa.
- Zvakanakira zve solvent-isina macomposites
Parizvino, kudziya kwepamusoro-tembiricha yekubika uye sterilization zvigadzirwa muindasitiri zvinonyanya kushandisa solvent based adhesives yekuoma musanganiswa.Kuenzaniswa neyakaoma composite, kushandisa solvent-isina composite kubika zvigadzirwa kune zvinotevera zvakanakira:
4.1kushanda zvakanaka zvakanakira
Kubatsira kwekushandisa-solvent-isina adhesives kunonyanya kuwedzera kwehuwandu hwekugadzira.Sezvinozivikanwa, kushandisa yakaoma composite tekinoroji kugadzira-tembiricha yekubikira uye sterilization zvinhu zvine yakaderera kugadzirwa kumhanya, kazhinji kutenderera 100m/min.Mamwe mamiriro emidziyo uye kutonga kwekugadzira kwakanaka, uye anogona kuwana 120-130m/min.Zvisinei, mamiriro acho haana kunaka, chete 80-90m / min kana kunyange pasi.Iyo yakakosha kuburitsa simba rekunyungudutsa-isina adhesives uye inoumbwa michina iri nani pane iyo yakaoma composite, uye inosanganiswa kumhanya inogona kusvika 200m/min.
4.2mutengo mukana
Huwandu hweglue inoiswa kune yakanyungudika yakavakirwa-yepamusoro-tembiricha yekubika glue yakakura, inodzorwa pa4.0g/m.² Kuruboshwe uye kurudyi, muganho hausi pasi pe3.5g/m²;Kunyange kana huwandu hweglue inoshandiswa kune yakanyungudika-isina kubika glue iri 2.5g/m² Kana ichienzaniswa neyakagadziriswa nzira, ine zvakare yakakosha mutengo mukana nekuda kweiyo yakakwira yekunamatira yemukati.
4.3Zvakanakira mukuchengetedza uye kuchengetedzwa kwezvakatipoteredza
Munguva yekushandiswa kweiyo yakanyungudika yakavakirwa-yepamusoro-tembiricha yekubika glue, yakawanda yakawanda ethyl acetate inoda kuwedzerwa kune dilution, izvo zvinokanganisa kuchengetedza kwezvakatipoteredza uye yekugadzira workshop kuchengetedza.Izvo zvinotarisanawo nedambudziko repamusoro-soro residue.Uye zvinonamira-zvisina solvent hazvina kana hanya nazvo zvachose.
4.4Simba rekuchengetedza zvakanakira
Iyo yekurapa reshiyo ye solvent based adhesive composite zvigadzirwa yakakwira, zvakanyanya pa50° C kana pamusoro;Nguva yekukura inofanira kuva maawa 72 kana kupfuura.Iyo yekumhanyisa yekumhanyisa yekunyungudutsa-isina kubika glue inokurumidza, uye kudiwa kwekurapa tembiricha uye nguva yekurapa ichave yakaderera.Kazhinji, tembiricha yekurapa ndeye 35° C~48° C, uye nguva yekurapa ndeye 24-48 maawa, ayo anogona kunyatsobatsira vatengi kupfupisa kutenderera.
5. Mhedziso
Muchidimbu, zvinonamira zvisingaite zvinonyungudutsa, nekuda kwezvimiro zvawo zvakasiyana, mabhizinesi ekudhinda mavara, mabhizinesi anonamira, uye mabhizinesi ekugadzira-isina solvent-isina kompositi mabhizinesi akabatana uye akatsigirana kwemakore mazhinji, achipa ruzivo rwakakosha uye ruzivo muminda yavo.Isu tinotenda kuti zvinonamira zvisingaite zvinonyungudutsa zvine huwandu hwakawanda hwekushandisa mune ramangwana.Uzivi hwekuvandudza hweKangda New Materials ndewe "tave tichishanda nesimba kugadzira kukosha kwevatengi uye kuvafambisa".Tinovimba kuti zvigadzirwa zvedu zvekupisa zvekupisa zvakanyanya zvinogona kubatsira mamwe mabhizinesi ekudhinda mavara kuongorora minda mitsva yesolvent-isina composite application.
