nkhani

Zowonjezera mankhwala opangira mapepala nthawi zambiri zimagwiritsidwa ntchito pamakampani opanga mapepala, ndipo mitundu yawo ndi yotakata komanso yogwiritsidwa ntchito kwambiri, ndipo ntchito zawo zimawonekera makamaka pazinthu izi:

01 Kupititsa patsogolo luso la kupanga

Pofuna kupititsa patsogolo kuthamanga kwa madzi a kumapeto kwa makina a pepala ndikufulumizitsa kutuluka kwa madzi mu cadre, thandizo la fyuluta likhoza kuwonjezeredwa kuti lipititse patsogolo kupanga. Pofuna kupangitsa kuti zamkati zikhale zofanana komanso zolimba, mordant ndi dispersant zikhoza kuwonjezeredwa. Mukakulitsa rosin, kuwonjezera synergist kumatha kupititsa patsogolo kukula kwake. Kuphatikiza apo, mapepala otayidwanso ogwiritsidwa ntchitonso amakhala ndi inki ndi zinthu zina, ndipo zotayira zotayira mapepala zimatha kuwonjezeredwa kuti zipange zamkati zenizeni.

02 Konzani bwino ndikupatseni mapepala apadera

Mwachitsanzo, pepala la thumba la simenti limafuna mphamvu zambiri komanso kutsekemera kwabwino, ndipo kugunda sikungakhale kwakukulu pamene akumenya. Pofuna kupititsa patsogolo mphamvu ya pepala, othandizira mphamvu zowuma nthawi zambiri amawonjezeredwa. Zopukutira ndi zopukutira zamapepala ziyenera kukhala zofewa ngati thonje, ndipo zopukuta sizingagwedezeke, ndipo zofewa za pepala zidzawonjezedwa.

03 Chepetsani zinyalala ndikusunga zopangira

Mwachitsanzo, kuwonjezera zosungira ndi zomangira pazamkati zimatha kupititsa patsogolo kuchuluka kwa zodzaza ndi ulusi wabwino, kuchepetsa kutayika, kusunga zinthu zopangira, komanso kuchepetsa kuipitsidwa kwa madzi oyipa.

04 Chotsani zolepheretsa kupanga

M'nyengo yachilimwe, matope nthawi zambiri amakhala m'matangi amatope, akasinja a mesh, kapena mapaipi amadzi oyera ndipo amawola, zomwe zimalepheretsa kupanga. Tsopano pali zosiyanasiyana mkulu dzuwa, otsika kawopsedwe, zodzitetezera kuwola, akhoza kupha mabakiteriya ndi odana ndi dzimbiri, sudzayambitsa kuipitsa.

Ngati zamkati sizitsukidwa ndikusakanikirana ndi mpweya, zimatulutsa thovu ndi zamkati zoyandama, zomwe zimakhala zovulaza ku khalidwe ndi ntchito ya pepala. Pofuna kuthetsa kuvulaza kwa thovu, defoamer ndi degassing wothandizira angagwiritsidwe ntchito.

05 Sinthani magwiridwe antchito

Kugwiritsa ntchito chotsukira bulangeti kumatha kufulumizitsa kuchapa bulangeti ndikusunga bulangeti laukhondo. Zomatira nthawi zambiri zimawonjezeredwa ku zokutira kuti pepala lokutidwa likhale labwino. Kuphatikiza kwa dispersant kumatha kuchepetsa kukhuthala kwa zokutira, kulimbikitsa ntchito yopanga ndikupanga yunifolomu yophimba. Kuphatikiza kwa zomatira kumatha kupititsa patsogolo kukana kwamadzi kwa zokutira.
