Pfupiso: Kana uchida kugadzira nzira isina solvent-free compound uchishandisa zvishoma nezvishoma, zvakakosha kusarudza composite adhesive nemazvo. Chinyorwa chino chinosuma masarudzo ekusarudza composite adhesive yakakodzera composite substrates nemaumbirwo akabatanidzwa.
Nekukura uye kufarirwa kwehunyanzvi hwekugadzira zvinhu zvisina solvent-free composite, zvinhu zvakatetepa zvemafirimu zvakawanda zvinogona kushandiswa kugadzira zvinhu zvisina solvent-free composite. Kuti ushandise tekinoroji isina solvent-free composite zvakanaka, zvakakosha kusarudza chinhu chakakodzera chinonamira. Pazasi, zvichibva pane zvakaitika kumunyori, tichatsanangura masarudzo ekugadzira chinhu chisina solvent-free management chakakodzera.
Parizvino, lamination yakaoma uye lamination isina solvent zvinoshanda pamwe chete. Saka, kuti tigadzirise kushandiswa kwetekinoroji ye lamination isina solvent, chinhu chekutanga ndechekunzwisisa zvizere chimiro chechigadzirwa chefekitori yekurongedza, kupatsanura chimiro chechigadzirwa zvakadzama, kupatsanura maumbirwo echigadzirwa anogona kushandiswa pa lamination isina solvent, uye wobva wasarudza namira yakakodzera isina solvent. Saka, ungasarudza sei zvinobudirira manamatiro asina solvent? Enzanisa chimwe nechimwe kubva pane zvinotevera.
- simba rekunamira
Nekuda kwekuoma uye kusiyana kwezvinhu zvekurongedza, magadzirirwo epamusoro pezvinhu zvepurasitiki anosiyanawo zvikuru. Zvinhu zvekurongedza zvinochinjika zvine hunhu hwakasiyana, senge PE, BOPP, PET, PA, CPP, VMPET, VMCPP, nezvimwewo. Kune zvimwe zvinhu zvisingawanzo shandiswa pakurongedza zvinochinjika, zvakaita sePS, PVC, EVA, PT, PC, bepa, nezvimwewo. Saka, namati isina solvent inosarudzwa nemabhizinesi inofanira kunge yakanamatira zvakanaka pazvinhu zvakawanda zvekurongedza zvinochinjika.
- Kudzivirira tembiricha
Kusagona kupisa kunosanganisira zvinhu zviviri. Chimwe ndechekusagona kupisa zvakanyanya. Parizvino, zvekudya zvakawanda zvinoda kuvhiyiwa kuti zvisashandise mushonga unouraya utachiona, zvimwe zvinovhiyiwa kuti zvisashandise mushonga unouraya utachiona pa 80-100 degrees.° C, nepo dzimwe dzichiiswa mushonga wekuuraya utachiona pa100-135° C. Nguva yekuvhiyiwa inosiyana, mimwe ichida maminetsi gumi kusvika makumi maviri uye mimwe ichida maminetsi makumi mana. Mimwe ichiri kuvhiyiwa ne ethylene oxide. Zvinhu zvakasiyana zvine nzira dzakasiyana dzevhiyiwa. Asi glue isina solvent yakasarudzwa inofanira kusangana nezvinodiwa izvi zvekupisa kwakanyanya. Bhegi harigone kudzima kana kuchinja mushure mekupisa kwakanyanya. Pamusoro pezvo, zvinhu zvakanatswa neglue isina solvent zvinofanira kukwanisa kumira kupisa kwakanyanya kwe200° C kana kunyange 350° C ipapo ipapo. Kana izvi zvikasakwanisika, kuvhara kupisa kwebhegi kunogona kupatsanurwa.
Chechipiri inodzivirira kupisa kwakaderera, iyo inozivikanwawo sekudzivirira kuomarara. Zvinhu zvakawanda zvekurongedza zvakapfava zvine chikafu chakaomeswa nechando, izvo zvinoda manamatisi asina zvinonyungudutsa kuti akwanise kumira tembiricha yakaderera. Patembiricha yakaderera, zvinhu zvinosimbiswa nemanamatisi pachawo zvinowanzooma, kuputsika, kutsemuka, uye kutyoka. Kana zviitiko izvi zvikaitika, zvinoratidza kuti manamatisi akasarudzwa haagone kumira tembiricha yakaderera.
Saka, pakusarudza manamatisi asina zvinonyungudutsa, kunzwisisa kwakadzama uye kuyedzwa kwekudzivirira kupisa kwakakosha.
3. Hutano neKuchengetedzeka
Zvinonamira zvisina solvent zvinoshandiswa mukupakira chikafu nemishonga zvinofanira kuva nehutsanana hwakanaka uye kushanda zvakanaka. Mitemo yakasimba iripo munyika dzakasiyana-siyana pasi rose. US FDA inoronga zvinonamira zvinoshandiswa muzvinhu zvinonamira zvekudya nemishonga sezvinowedzera, ichiganhurira zvinhu zvinoshandiswa kugadzira zvinonamira uye ichirambidza kushandiswa kwezvinhu zvisina kuiswa mune runyorwa rwezvinhu zvakagadziriswa, Uye zvinhu zvinonamira zvakagadzirwa nezvinonamira izvi zvakakamurwa uye zvakaganhurirwa mukushandiswa kwazvo kwetembiricha, kusanganisira kushandiswa kwetembiricha yemukamuri, kushandiswa kwekubikisa disinfectant, kushandiswa kwe122 ° C steaming sterilization, kana 135 ° C uye pamusoro pekushandiswa kwekupisa kwakanyanya. Panguva imwe chete, zvinhu zvekuongorora, nzira dzekuyedza, uye zviratidzo zvehunyanzvi zvezvinhu zvekupakira zvakagadzirwawo. Kunewo zvisungo zvakakosha uye zvirambidzo muChina standard GB9685.Naizvozvo, zvinonamira zvisina solvent zvinoshandiswa kune zvigadzirwa zvekutengeserana kunze kwenyika zvinofanirwa kutevedzera mitemo yemuno.
4. Kusangana nezvinodiwa zvemapurogiramu akakosha
Kushandiswa kwakapararira kwezvisanganiswa zvisina solvent mumunda wekupakira zvinochinjika kwakasimudzira kushandiswa kwazvo muminda ine chekuita nazvo. Parizvino, kune nzvimbo dzakakosha kwadzakashandiswa:
4.1 Kurongedza pepa rePET risina chinyungudutsiro
Mapepa ePET anonyanya kugadzirwa nezvinhu zvePET zvine ukobvu hwe0.4mm kana kupfuura. Nekuda kwekukora uye kuomarara kwechinhu ichi, zvakakosha kusarudza namati isina solvent ine kunamira kwekutanga kwakanyanya uye viscosity kuti ugadzire chinhu ichi. Chigadzirwa chakagadzirwa nemhando iyi yezvinhu zvakasanganiswa chinowanzo fanirwa kugadzirwa mumhando dzakasiyana-siyana, zvimwe zvacho zvinoda kudhindwa, saka zvinodiwa kuti ganda rive rakasimba zvakanyanya. WD8966 yakagadzirwa neKangda New Materials ine kunamira kwekutanga kwakanyanya uye kuramba kudhindwa, uye yakashandiswa zvinobudirira muPET sheet composite.
4.2 Kurongedza jira risina kusanganiswa risina kunyungudutswa
Machira asina kurukwa anoshandiswa zvakanyanya uye ane mhando dzakasiyana-siyana. Kushandiswa kwemachira asina kurukwa munzvimbo dzisina solvent kunonyanya kuenderana nekukora kwejira risina kurukwa uye huwandu hwemafibers. Zvichitaurwa, kana jira risina kurukwa rakawanda, zvinoita kuti solvent-free composite ive nani. Parizvino, polyurethane hot melt adhesive imwe chete inonyanya kushandiswa pamachira asina solvent-free composite asina solvent.
