M'mayiko ogulitsa mafakitale, kumene kukhudzana ndi mankhwala owopsa kumakhaladi tsiku ndi tsiku, chitetezo cha ogwira ntchito ndichofunika kwambiri. Zina mwa zida zofunika kwambiri zodzitchinjiriza m'malo oterowo ndi suti zotsimikizira za asidi. Zovala zapaderazi zapangidwa kuti zipereke chitetezo chofunikira kuopsa kwa zinthu za acidic, kuwonetsetsa kuti ogwira ntchito amakhala otetezeka komanso otetezedwa pamene akugwira ntchito zina mwazoopsa kwambiri.
Cholinga:Zovala zogwira ntchito zoteteza asidi amapangidwa kuti asalowe m'malo mwa ma asidi, kuletsa zinthu zowononga izi kuti zisakhumane ndi khungu. Zovalazo nthawi zambiri zimapangidwa kuchokera kuzinthu zamphamvu kwambiri, zosagwirizana ndi mankhwala, monga ulusi wa polyester wokutidwa ndi polyurethane, mphira wapadera, kapena zinthu zina zopangira. Zidazi zimasankhidwa mosamala kuti zitha kupirira kukhudzana ndi mitundu yambiri ya zidulo, kuphatikizapo zowononga kwambiri monga sulfuric acid, hydrochloric acid, ndi nitric acid.
Kuphatikiza pa zinthu zosagwirizana ndi asidi, suti zogwirira ntchitozi nthawi zambiri zimapangidwira kuti zisalowe madzi ndi mafuta, zomwe zimapereka chitetezo chokwanira ku zoopsa zosiyanasiyana zamakampani. Zida zomwe zimagwiritsidwa ntchito sizongolimbana ndi kulowa kwa mankhwala komanso zimakhala zolimba mokwanira kuti zipirire zofuna zakuthupi za ntchito ya mafakitale, monga ma abrasion, punctures, ndi kutentha kwakukulu. Mapangidwe a sutizi amaganiziranso kufunikira kwa kuyenda ndi chitonthozo, kulola ogwira ntchito kuyenda momasuka ndikuchita ntchito zawo moyenera popanda kusokoneza chitetezo.
Kusankha suti yoyenera yotsimikizira asidi kumaphatikizapo kuganizira mozama zinthu zingapo. Choyamba, ndikofunikira kumvetsetsa mitundu yeniyeni ya ma asidi ndi mankhwala omwe ogwira ntchito angakumane nawo. Ma asidi osiyanasiyana ali ndi mitundu yosiyanasiyana ya dzimbiri, ndipo sutiyo iyenera kupangidwa kuti ipereke chitetezo chokwanira kuzinthu zomwe zimagwiritsidwa ntchito pantchito. Kuchuluka kwa ma asidiwa ndi chinthu chofunikira kwambiri-zovala zomwe zingateteze ku njira zochepetsera sizingakhale zokwanira kwa ma asidi ambiri.
Malo ogwirira ntchito pawokha amakhala ndi gawo lalikulu pakusankha mtundu woyenera kwambiri wa suti. Mwachitsanzo, m'malo omwe kumakhala kutentha kwambiri kapena chinyezi, ogwira ntchito amafunikira suti zomwe zimateteza ku asidi komanso zomwe zimapatsa mpweya wabwino kuti asatenthedwe. Kukwanira ndi kutonthoza kwa sutiyi ndizofunikanso kulingalira; suti yomwe imakhala yothina kwambiri kapena yambiri imatha kuletsa kuyenda ndikuchepetsa zokolola, pomwe suti yokwanira bwino imalola ogwira ntchito kuti azichita bwino ntchito zawo popanda kusokoneza chitetezo.
Kutsiliza
Zovala zogwirira ntchito zosagwirizana ndi asidi ndi gawo lofunikira kwambiri lachitetezo m'mafakitale momwe ogwira ntchito amakumana ndi mankhwala owopsa komanso owononga. Popereka chotchinga chodalirika motsutsana ndi ma asidi, sutizi zimateteza ogwira ntchito kuvulala koopsa ndikuwonetsetsa kuti atha kugwira ntchito zawo mosamala komanso moyenera. Pamene mafakitale akupitilira kukula, momwemonso zida zodzitchinjiriza zomwe zimateteza omwe ali pamzere wakutsogolo, zida zogwirira ntchito zokhala ndi asidi zimakhalabe chinthu chofunikira pakuyesa kuteteza ogwira ntchito m'malo owopsa.
