Kumanga matope pogwiritsa ntchito makina kwakhala kukuyesani ndikulimbikitsidwa kwa zaka zambiri ku China, koma palibe kupita patsogolo kwakukulu komwe kwachitika. Kuwonjezera pa kukayikira kwa anthu za kusintha kwakukulu komwe kumanga matope pogwiritsa ntchito makina kungabweretse pa njira zachikhalidwe zomangira, chifukwa chachikulu ndichakuti pansi pa njira yachikhalidwe, matope osakanikirana pamalopo angayambitse kutsekeka kwa mapaipi ndi mapulojekiti ena panthawi yomanga matope pogwiritsa ntchito makina chifukwa cha mavuto monga kukula kwa tinthu tating'onoting'ono ndi magwiridwe antchito. Zolakwika sizimangokhudza kupita patsogolo kwa zomangamanga, komanso zimawonjezera mphamvu yomanga, zomwe zimapangitsa kuti antchito aziopa zovuta ndikuwonjezera zovuta zokweza zomangamanga pogwiritsa ntchito makina.
M'zaka zaposachedwapa, chifukwa cha kukhazikitsidwa kwa mafakitale akuluakulu a matope osakaniza ndi madzi m'dziko lonselo, ubwino ndi kukhazikika kwa matope kwatsimikizika. Komabe, matope osakaniza ndi madzi amakonzedwa ndikupangidwa ndi mafakitale. Ponena za zipangizo zopangira zokha, mtengo wake uyenera kukhala wokwera kuposa wa matope osakaniza ndi madzi m'malo mwake. Ngati kupaka pulasitala pamanja kukupitirira, sikudzakhala ndi mwayi wopikisana ndi matope osakaniza ndi madzi m'malo mwake, ngakhale pali mayiko ena Chifukwa cha mfundo ya "ban cash", mafakitale atsopano a matope osakaniza ndi madzi akuvutikabe kupeza ndalama, ndipo pamapeto pake amalephera kugwira ntchito.
Chidule cha momwe makina opopera matope amagwirira ntchito
Poyerekeza ndi matope achikhalidwe omwe amasakanizidwa pamalopo, kusiyana kwakukulu kwa matope opopera ndi makina ndi kuyambitsa zosakaniza zingapo monga hydroxypropyl methyl cellulose ether zomwe zingathandize kuti matope agwire bwino ntchito, kotero kuti matope atsopano osakanikiranawo akhale osavuta kugwira ntchito, kuchuluka kwa madzi osungira, komanso kugwira ntchito bwino pambuyo popopera mtunda wautali komanso kutalika kwambiri. Ubwino wake waukulu uli mu ntchito yake yomanga bwino komanso mtundu wabwino wa matope pambuyo poumba. Popeza matopewo ali ndi liwiro lalikulu poyambira kupopera, amatha kugwira bwino ntchito ndi substrate, zomwe zingathandize kuchepetsa kuphulika ndi kusweka.
Pambuyo poyesa kosalekeza, zapezeka kuti pokonzekera matope opaka pulasitala opopera ndi makina, gwiritsani ntchito mchenga wopangidwa ndi makina wokhala ndi tinthu tating'onoting'ono tosakwana 2.5mm, ufa wa miyala wochepera 12%, komanso kukula koyenera, kapena tinthu tating'onoting'ono tosakwana 4.75mm ndi matope ochepera 5%. Pamene kuchuluka kwa madzi osungira matope atsopano osakanikirana kumayang'aniridwa pamwamba pa 95%, kusinthasintha kumayendetsedwa pafupifupi 90mm, ndipo kutayika kwa kusinthasintha kwa maola awiri kumayendetsedwa mkati mwa 10mm, matopewo amakhala ndi magwiridwe antchito abwino opopera ndi kupopera, ndipo mawonekedwe a matope opangidwawo ndi osalala komanso oyera, matopewo ndi ofanana komanso olemera, osagwedezeka, opanda mabowo kapena ming'alu.
Kukambirana za Zowonjezera Zopangira Mtondo Wopopera ndi Makina
Njira yopangira matope opopera ndi makina makamaka imaphatikizapo kusakaniza, kupopera ndi kupopera. Poganizira kuti njirayo ndi yoyenera komanso kuti zinthu zopangira zili bwino, ntchito yayikulu ya chowonjezera cha matope opopera ndi makina ndikukonza bwino matope osakaniza atsopano ndikukweza magwiridwe antchito a matope. Chifukwa chake, chowonjezera cha matope opopera ndi makina chimapangidwa ndi chosungira madzi ndi chopopera. Hydroxypropyl methylcellulose ether ndi chothandizira chabwino kwambiri chosunga madzi, chomwe sichingowonjezera kukhuthala kwa matope, komanso chimawongolera kwambiri kusinthasintha kwa matope ndikuchepetsa kulekanitsidwa ndi kutuluka magazi pansi pa mtengo womwewo wofanana. Chothandizira chopopera nthawi zambiri chimakhala ndi chothandizira cholowetsa mpweya ndi chothandizira chochepetsera madzi. Panthawi yosakaniza matope osakaniza atsopano, thovu laling'ono la mpweya limayambitsidwa kuti lipange zotsatira za mpira, zomwe zimachepetsa kukana kukangana pakati pa tinthu tating'onoting'ono ndikuwongolera magwiridwe antchito a matope. Pa nthawi yopopera matope opopera ndi makina, kugwedezeka pang'ono komwe kumachitika chifukwa cha kuzungulira kwa pampu yotumizira screw kumapangitsa kuti matope omwe ali mu hopper akhale osasunthika, zomwe zimapangitsa kuti pakhale kusinthasintha pang'ono pamwamba ndi kusinthasintha kwakukulu pansi, zomwe zimapangitsa kuti mapaipi atsekeke mosavuta makina akamayendetsa, ndipo Pambuyo poumba, ubwino wa matopewo sufanana ndipo umakhala wovuta kuumitsa ndi kusweka. Chifukwa chake, popanga zowonjezera zophatikizika za matope ophulitsa makina, zokhazikika zina ziyenera kuwonjezeredwa bwino kuti zichepetse kufalikira kwa matope.
Pamene ogwira ntchito ankachita kuyesera kwa matope opopera ndi makina, mlingo wa chowonjezera chophatikiza unali 0.08%. Chopopera chomaliza chinali chogwira ntchito bwino, chimagwira ntchito bwino kwambiri popopera, sichinagwedezeke panthawi yopopera, ndipo makulidwe apamwamba kwambiri a kupopera kamodzi amatha kufika 25px.
