Pankhani ya pepala, funso lomwe nthawi zambiri amafunsidwa ndi makasitomala ndiloti, kodi mumagulitsa pepala la A4?
Zikuoneka kuti kumvetsa kwa anthu pa zinthu zamapepala kumangokhala m'mapepala athu omwe amagwiritsidwa ntchito kwambiri, m'mabuku ndi zinthu zina zomwe anthu wamba.Koma lero tidzayambitsa mtundu wa mapepala omwe simunamvepo ndi kuthekera kwakukulu - mapepala opanda sulfure.
Tikakamba za dzina la pepala lopanda sulfure, ngati simunagwirepo, mungakhale mukudabwa funso.Kodi pali kugwirizana kulikonse pakati pa sulfure ndi pepala?
Izi ndizokhudza kupanga mapepala amakono.Popanga mapepala amapepala amakono, chinthu chofunikira kwambiri cha inorganic chimagwiritsidwa ntchito - aluminium sulphate (dzina lina lake ndi alum)
Makina opangira mapepala amawonjezera aluminiyamu sulphate ngati chopangira kupanga mapepala, kupereka mapepala odana ndi kuvala, odana ndi madzi, anti-emulsion, anti-corrosion properties, ndipo nthawi yomweyo amawongolera kusalala kwa pepala ndikupatsa madzi- zochokera kusinthasintha kusindikiza.
Pochita izi, ndizosapeweka kuti mapepala opangidwa adzakhala ndi sulfure.
Komabe, m'mafakitale ena ogwiritsira ntchito anthu apamwamba kwambiri, zomwe sulfure zili m'mapepala ziyenera kuyendetsedwa mochepa kwambiri.
Poyang’anizana ndi kufunika kumeneku, mphero zamapepala zinapitirizabe kuyesa kuwongolera njira yopangira mapepala, ndipo pomalizira pake mapepala opanda sulfure anabadwa.
Mapepala omwe amagwiritsidwa ntchito m'madera osiyanasiyana ali ndi zosiyana zawo, monga mapepala a mafakitale ndi mapepala apanyumba.
Mapepala a mafakitale monga mapepala osindikizira, mapepala opanda sulfure, mapepala oyamwa mafuta, mapepala okulungidwa, mapepala a kraft, mapepala a fumbi, ndi zina zotero, mapepala apanyumba monga mabuku, zopukutira, nyuzipepala, mapepala a chimbudzi, etc.
Ndiye tiyeni tifotokoze kusiyana kwa mapepala opanda sulfure ndi mapepala athu omwe amagwiritsidwa ntchito mofala.
Swopanda ulfur pepala
Pepala lopanda sulfure ndi pepala lothandizira lapadera la PCB siliva popanga ma board board.Cholinga chachikulu chogwiritsira ntchito mapepala amtunduwu ndikupewa kutengera kwa siliva ndi sulfure mumlengalenga, kupangitsa kuti ikhale yachikasu.Ndipo kugwiritsa ntchito pepala lopanda sulfure kumatha kupewa zomwe zimachitika pakati pa sulfure ndi siliva, zomwe zingayambitse zolakwika zina za pcb.
Nthawi yomweyo, pepala lopanda sulfure limapewanso kusintha kwamankhwala pakati pa siliva mu electroplating yomalizidwa ndi sulfure mumlengalenga, zomwe zimapangitsa kuti chinthucho chisanduke chikasu.Choncho, mankhwalawa ayenera kupakidwa ndi pepala lopanda sulfure mwamsanga pamene mankhwalawo atsirizidwa, ndipo magolovesi opanda sulfure ayenera kuvala pokhudza mankhwala, ndipo sayenera kukhudza pamwamba pa electroplated.
Mawonekedwe a pepala lopanda sulfure: pepala lopanda sulfure ndi loyera, lopanda fumbi, logwirizana ndi ROHS, liribe sulfure (S), chlorine (CL), lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls ndi polybrominated diphenyl ethers.Itha kugwiritsidwa ntchito bwino kumakampani opanga zamagetsi zamagetsi a PCB komanso makampani opanga ma electroplating a hardware.
Kugwiritsa ntchito mapepala opanda sulfure: omwe amagwiritsidwa ntchito kwambiri pakuyika siliva, monga matabwa ozungulira, ma LED, matabwa ozungulira, ma terminals, zinthu zoteteza chakudya, magalasi agalasi, ma CD a Hardware, kulekanitsa mbale zachitsulo chosapanga dzimbiri, kuyika chakudya, ndi zina zambiri.
Mapepala wamba
Zopangira zopangira mapepala zimakhala ndi ulusi wazomera.Kuphatikiza pa zigawo zitatu zazikulu za cellulose, hemicellulose ndi lignin, pali zigawo zina zomwe zili ndi zochepa, monga utomoni ndi phulusa.Kuonjezera apo, pali zowonjezera zowonjezera monga sodium sulfate.Ndipo mapepala wamba amapangidwa makamaka ndi ulusi wa zomera, monga matabwa, udzu, ndi zina zotero. Sibwino kuti apange pepala la electroplating chifukwa cha zonyansa zambiri.
Kenako tiyeni tiwone zomwe mafakitale amagwiritsa ntchito pamapepala opanda sulfure:
1. Kukwaniritsa masking zotsatira pa mankhwala osiyanasiyana, pamene pamwamba pakufunika processing kwambiri monga kupopera mankhwala ndi etching asidi, akhoza kuphimba pamwamba kuti safuna kupopera mbewu mankhwalawa ndi etching asidi.Popopera mbewu mankhwalawa mumitundu yosiyanasiyana, zotsatira za shading ndizofunikira kwambiri.
2. Gwiritsani ntchito mapepala opanda sulfure poteteza kapena kulongedza.Zogulitsa za filimu yoteteza pepala yopanda sulfure zimagwiritsidwa ntchito kwambiri, ndipo ndizoyenera kuteteza mbale, mbiri, zida za aluminiyamu ndi matabwa a PCB.Ndioyenera kugwiritsidwa ntchito m'zipinda zosiyanasiyana zoyera, mafakitale akuluakulu ndi ang'onoang'ono amagetsi ndi mafakitale a PCB board, mafakitale a LCD, mapulojekiti a msonkhano olondola, mafakitale a semiconductor, mafakitale optical disc, laboratories, etc.
Kugwiritsiridwa ntchito kwa mafakitale kwa mapepala opanda sulfure ndi kwakukulu kotero kuti monga chotchingira chotetezera zinthu zosiyanasiyana, mapepala opanda sulfure alidi njira yabwino koposa.Kuphatikiza apo, pepala lopanda sulfure ndi mtundu wa pepala lomwe ndi lotsika mtengo komanso lokonda zachilengedwe, ndipo lingagwiritsidwenso ntchito kupulumutsa ndalama zakuthupi.
Shenzhen Beite amatha kupereka pepala lopanda sulfure ndi ntchito yosinthidwa makonda.
Ma parameters azinthu ndi awa:
Kulemera kwake: 40gsm-120gsm,
Mtengo wa Orthogonality: 787 * 1092mm,
Mtengo wowolowa manja: 898 * 1194mm,
sulfure dioxide ≤50ppm,
Kuyesa kwa tepi yomatira: pamwamba kulibe vuto lakugwa tsitsi.
makonda kukula.
Ngati mukufuna kudziwa zambiri zamakampani athu, mutha kupita patsamba lathu lovomerezekahttps://www.btpurify.com/kuti mudziwe zambiri.
