Nezve bepa, mubvunzo unowanzo kubvunzwa nevatengi ndewekuti, unotengesa bepa reA4 here?
Zvinoita sekuti manzwisisiro eruzhinji ezvigadzirwa zvemapepa anongogara mumapepa edu anowanzo shandiswa kudhinda, mabhuku ekunyorera uye zvimwe zvigadzirwa zvisiri pamutemo.Asi nhasi tichazivisa rudzi rwepepa rausina kumbonzwa nepamusoro-soro - mapepa asina sulfur.
Apo patinotaura pamusoro pezita repepa risina sulfuri, kana usina kuibata, unogona kunge uchishamisika mubvunzo.Pane here kubatana pakati pesarufa nebepa?
Izvi ndezvekugadzirwa kwemapepa emazuva ano.Mukugadzira mapepa emapepa emazuva ano, chinhu chakakosha zvikuru chinowanzo shandiswa - aluminium sulfate (rimwe zita rayo ialum)
Mapepa ezvigayo anowedzera aluminium sulfate seanogadzira saizi mukugadzira mapepa, achipa bepa anti-kupfeka, anti-mvura, anti-emulsion, anti-corrosion zvivakwa, uye panguva imwechete inovandudza kutsvedzereka kwepepa uye kuripa mvura- yakavakirwa kudhinda kuchinjika.
Mukuita uku, hazvidzivisiki kuti zvigadzirwa zvemapepa zvinogadzirwa zvichava nesarufa.
Nekudaro, mune mamwe maindasitiri epamusoro-ekupedzisira ekushandiswa kwevagari, iyo sulfur yemukati mupepa inoda kudzorwa mukati meiyo yakaderera kwazvo.
Takatarisana nezvinodiwa izvi, zvigayo zvemapepa zvakaramba zvichiedza kuvandudza nzira yekugadzira mapepa, uye pakupedzisira bepa risina sulfur rakazvarwa.
Mapepa anoshandiswa munzvimbo dzakasiyana ane misiyano yawo, senge mapepa eindasitiri uye mapepa eimba.
Pepa remaindasitiri senge bepa rekudhinda, bepa risina sulfuri, pepa rinonyura mafuta, pepa rekuputira, kraft bepa, guruva rinodzivirira guruva, nezvimwewo, mapepa epamba akadai semabhuku, napkins, mapepanhau, chimbuzi, nezvimwe.
Zvadaro ngatitsanangure musiyano uri pakati pepepa risina sulfur nebepa redu rinowanzoshandiswa.
Sulfur-isina bepa
Pepa reSulfur-isina bepa rakakosha kutsigira PCB sirivheri kugadzirisa mune redunhu bhodhi vanogadzira.Chikonzero chikuru chekushandisa rudzi urwu rwepepa ndechekudzivirira kemikari yesirivheri nesarufa mumhepo, zvichiita kuti iite yero.Uye kushandisa sarufa-isina bepa kunogona kudzivirira kuita pakati pesarufa nesirivheri, izvo zvinogona kutungamirira kune kumwe kukanganisa kwepcb.
Panguva imwecheteyo, bepa risina sulfuri rinodzivirirawo kuita kwemakemikari pakati pesirivheri mu electroplating yapera chigadzirwa uye sarufa iri mumhepo, zvichiita kuti chigadzirwa chive chero.Nokudaro, chigadzirwa chacho chinofanira kuiswa nepepa risina sulfuri nokukurumidza sezvinobvira mushure mokunge chigadzirwa chapera, uye magirafu asina sulfuri anofanira kupfekwa pakubata chigadzirwa, uye haafaniri kubata electroplated surface.
Zvimiro zvepepa risina sulfur: bepa risina sulfuri rakachena, risina guruva, ROHS-inopindirana, haina sulfur (S), chlorine (CL), lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls uye polybrominated diphenyl ethers.Inogona kuiswa zvirinani kuPCB redunhu bhodhi remagetsi indasitiri uye hardware electroplating indasitiri.
Sulfur-isina mapepa ekushandisa: inonyanya kushandiswa kurongedza-silver-plated packaging, senge mabhodhi edunhu, maLED, mabhodhi edunhu, zviteshi zvehardware, zvigadzirwa zvekudzivirira chikafu, kurongedza magirazi, kurongedza kwehardware, kupatsanura simbi isina tsvina, kurongedza chikafu, nezvimwe, nezvimwe.
Bepa rakajairika
Izvo zvigadzirwa zvekugadzira mapepa zvakanyanya mafiber ezvirimwa.Mukuwedzera kune zvikamu zvitatu zvakakosha zve cellulose, hemicellulose uye lignin, kune zvimwe zvikamu zvine zvinyorwa zvishoma, zvakadai seresin uye madota.Mukuwedzera, kune zvinhu zvinobatsira zvakadai se sodium sulfate.Uye bepa rakajairwa rinonyanya kugadzirwa neshinda dzezvirimwa, sehuni, uswa, nezvimwewo. Haikodzere pepa re electroplating nekuda kwetsvina yakawandisa.
Zvadaro ngationei kuti ndezvipi zvinoshandiswa mumaindasitiri zviripo kune bepa risina sulfur:
1. Kuti uwane masking effect pazvigadzirwa zvakasiyana-siyana, apo nzvimbo inoda kushandiswa kwakadzama sekupfapfaidza uye etching acid, inogona kuvhara pasi iyo isingade kupfapfaidza uye acid etching.Paunenge uchipfapfaidza mumarudzi akasiyana-siyana, Iyo shading effect inonyanya kukosha.
2. Shandisa sarufa-isina mapepa ekudzivirira kana kurongedza.Zvigadzirwa zvesarufa-isina mapepa ekudzivirira firimu zvinoshandiswa zvakanyanya, uye zvakakodzerwa kuchengetedzwa kwepamusoro kweplateti, maprofiles, aluminium zvinhu uye PCB circuit board.Yakakodzera kushandiswa mumakamuri akasiyana akachena, mafekitori makuru uye madiki emagetsi uye mafekitori edunhu PCB, mafekitori eLCD, mapurojekiti egungano chaiwo, mafekitori esemiconductor, mafekitori edhisiki, marabhoritari, nezvimwe.
Iko kushandiswa kwemaindasitiri kwemapepa asina sulfuri kwakakura zvekuti semucheka wekudzivirira wezvigadzirwa zvakasiyana-siyana, bepa risina sulfur ndiro sarudzo yakanakisisa.Pamusoro pezvo, bepa risina sarufa zvakare imhando yemhando yepepa isingadhure uye ine hushamwari kwezvakatipoteredza, uye inogona kushandiswa zvakare kuchengetedza mari yezvinhu.
ShenZhen Beite yaigona kupa bepa risina sulfuri neyakagadzirirwa sevhisi.
