1. Mfundo yachitetezo cha nsalu za asidi-umboni wa asidi ndi mafuta osagwira madzi ndizomwe zimakhala zofanana, zomwe zimasintha maonekedwe a nsalu ya fiber pamwamba pomaliza. Nthawi zambiri, madzi amatsika pamtunda, chifukwa cha kugwedezeka kwa pamwamba ndi kugwirizana pakati pa madzi ndi olimba. Kupangitsa kuti madonthowo apange mawonekedwe osiyanasiyana. Monga momwe tawonetsera mu Chithunzi L, mukamalumikizana ndi Angle e = lao0, madontho amadzimadzi amakhala ngati mikanda, yomwe ili yabwino kwambiri yopanda chinyezi, yomwe ndi cholinga chachikulu cha chitetezo cha nsalu ku zakumwa zovulaza. Komabe, chifukwa nthawi zonse pamakhala kumamatira pakati pa magawo awiriwa, momwe kulumikizana kwa Angle ndi kofanana} so0 sizinachitikepo, ndipo ndi milandu yongoyerekeza yomwe ingapezeke kwambiri. Mwachitsanzo}bo0 kapena kupitilira apo. Pamene e = o0, ndiye kuti, dontho lamadzimadzi limapangidwira pamtunda wolimba, womwe ndi malire kuti malo olimba amanyowa ndi dontho lamadzimadzi. Kawirikawiri, nsalu yosamalizidwa imakhala mu chikhalidwe ichi pamene imakhudzana ndi madzi. Kumaliza pamwamba pa nsaluyo ndi kupanga kukhudzana kwa Angle e kukhala kwakukulu momwe mungathere, kotero kuti madzi nthawi zonse amakhala mu mawonekedwe a mkanda pamwamba pa nsalu, kuti akwaniritse cholinga chosanyowetsa komanso chosamata. 2. Ntchito zotetezafakitale ya pepala ya aramid
(1) Acid umboni ntchito zovala asidi ndi alkali umboni nsalu nsalu ntchito zikugwira ntchito asidi ogwira ntchito ndi asidi umboni ntchito zovala, amapangidwa ndi asidi umboni nsalu, mu dongosolo ayenera kukumana kolala zolimba, khafu zolimba ndi zolimba m'mphepete, ndi sangakhale ndi matumba owala, monga matumba ayenera kuwonjezeredwa kuti akwaniritse zofunikira zopanga. Malinga ndi muyezo wa GB12012-89 "zovala zantchito zotsimikizira asidi", pali zisonyezo zazikulu zotsatirazi zowunikira zovala zogwirira ntchito zotsimikizira asidi. Nthawi yolowera asidi: imatanthawuza nthawi ya asidi kulowa kuchokera pamwamba pa chakudya kupita mkati, kuwonetsedwa mumphindi.fakitale ya pepala ya aramidKutalikirana kwa nthawi, kumachita bwino. Antistatic nsalu, asidi wothamangitsa: amatanthauza sanali adhesion ntchito pamwamba pa utumiki pansi pa zochita za asidi, anasonyeza dzuwa index, ndi apamwamba kuchuluka, ndi zovuta kwambiri zomatira asidi. Kuchepetsa mphamvu ya acid leaching: kumatanthauza kusintha kwa kung'ambika kwa mphamvu yautumiki pambuyo pa kukokera kwa asidi. Kusintha kwakung'ono, kumakhala bwino. Tikamagwiritsa ntchito zovala zaumoyo acid, tiyenera kusamala kaye ngati ziwonetsero zazikuluzikulu zomwe wopanga amayesedwa amapereka zofunika kuti ateteze ntchito yathu.
(2) Zovala zoteteza mafuta ndi madzi oletsa mafuta oletsa mafuta komanso zoteteza madzi zimagwiritsidwa ntchito polumikizana pafupipafupi ndi malo opangira mafuta ndi madzi, monga mafuta, downhole ndi machining ntchito, zake zazikulu. zizindikiro zoteteza ndi zotsutsana ndi mafuta ndi madzi. Kukana kwamafuta ndi mafuta amchere oyera ndi n-heptane malinga ndi gawo la 20% ndi 80%, mphambu yake ndi mfundo 130; Malinga ndi 70% ndi 30% chiŵerengero, mphambu yake ndi 80 mfundo.fakitale ya pepala ya aramidIkani dontho lamadzi ofananira pa suti yoteteza mafuta ndi madzi. Pambuyo pa mphindi zitatu, yang'anani nsalu yomwe ili pansi pa madzi adontho kuchokera ku 45 degree Angle kuti muwone ngati ikuwonekera komanso yonyezimira, ndiye kuti nsaluyo siinyowa; Ngati pansi pa nsaluyo mdima kapena madontho akufalikira, ndikonyowa. Mtengo wochotsa mafuta suyenera kukhala wochepera 130 mfundo musanatsuke; Pambuyo kutsuka kwa nthawi 30, mtengo wothamangitsa mafuta uyenera kukhala wosachepera 80 mfundo. Madzi othamangitsira madzi ndi njira yopopera madzi pamwamba pa nsalu, nsalu ndi mzere wopingasa pa 45 digiri Angle, madzi otuluka ndi perpendicular kwa yopingasa malangizo kupopera mbewu mankhwalawa, onani mlingo wa madzi pamwamba, madzi osiyana. ntchito zothamangitsira zomwe zimagulitsa madzi ndizosiyana (Chithunzi 2)} Kufotokozera kwa kalasi yothamangitsa madzi: Gawo 1 - zonse zonyowa pamtunda 2 - theka lonyowa pamtunda, Nsalu yowotchera yoletsa makwinya, yomwe nthawi zambiri imatanthawuza kuchuluka kwa kachidutswa kakang'ono ka malo onyowetsa osalumikizidwa. Mzere wa 3 - Pamalo onyowa ndi madera ang'onoang'ono okha omwe sanagwirizane. Mzere wa 4 - palibe kunyowa pamwamba, koma pali madontho ang'onoang'ono a madzi pamtunda wa 5 - palibe kunyowa pamwamba, ndipo palibe madontho ang'onoang'ono amadzi pamwamba. Malinga ndi njira yomwe tafotokozayi, ogwiritsa ntchito amathanso kuyesa kuwunika kosavuta kwa zovala zoteteza mafuta komanso zoteteza madzi nthawi wamba. Ngakhale njira zodziwikiratu sizingakhale zofananira, chitetezo chambiri cha anti-acid ndi zovala zoteteza nsalu za alkali zitha kuganiziridwa.
