Pankhani ya matiresi, aliyense amawadziwa bwino. Matiresi pamsika ndi osavuta kupeza, koma ndikukhulupirira kuti anthu ambiri salabadira kwambiri nsalu za matiresi. Ndipotu, nsalu za matiresi ndi funso lalikulu. Lero, mkonzi adzalankhula za mmodzi wa iwo, pambuyo pake, nsalu singafotokoze mwachidule mawu ochepa chabe.
Lero, mkonzi akuwonetsa nsalu yomwe ili ndi mphamvu yoletsa madzinsalu za matiresi.
Kodi nsalu ya hydrophobic ndi chiyani?
Nsalu yopanda madzi - kwenikweni, imatanthauza kuteteza madzi kuti asalowe kuchokera kumbali imodzi ya nsalu kupita ku ina. Ndi mtundu watsopano wa nsalu zansalu, zopangidwa ndi polymer yopanda madzi komanso mpweya wopumira (PTFE filimu) kuphatikizapo nsalu yopangidwa ndi nsalu.
Chifukwa chiyani sichingalowe madzi?
Masiku ano, nsalu zambiri za matiresi sizikhala ndi madzi, pang'ono chabe madontho amadzi amamatira ku matiresi, zomwe zidzalowa mkati mwake pakapita nthawi, zomwe zimapereka malo abwino okhala ndi mabakiteriya ndi nthata. Ndipo kwa nsalu zopanda madzi, mkhalidwe woterowo sakadazindikirika. Mfundo yake ndi yakuti mumtundu wa nthunzi wa madzi, tinthu tating'onoting'ono tamadzi timakhala tating'ono kwambiri, ndipo molingana ndi mfundo ya kayendedwe ka capillary, imatha kulowa mkati mwa capillary kumbali ina, zomwe zimapangitsa kuti pakhale vuto la permeability. Pamene nthunzi yamadzi imalowa m'malovu amadzi, tinthu tating'onoting'ono timakhala tokulirapo. Chifukwa cha kugwedezeka kwapamwamba kwa madontho a madzi (mamolekyu amadzi amakoka ndi kukaniza wina ndi mzake), mamolekyu amadzi sangathe kuchoka m'malovu amadzi ndikulowa mbali ina, zomwe zimalepheretsa madzi kulowa ndikupangitsa kuti membrane ikhale yopanda madzi. Thensalu ya spunbond yopanda nsaluopangidwa ndi Liansheng alinso ndi mphamvu madzi ndipo chimagwiritsidwa ntchito kupanga matumba masika mu matiresi. Ndi yotchipa komanso yolimba.
Kodi zazikulu za nsalu zopanda madzi ndi ziti?
Ntchito zazikuluzikulu za nsalu zopanda madzi zimaphatikizapo kutsekereza madzi, kutulutsa chinyezi, kupuma, kutsekereza, komanso kukana mphepo. Pankhani yaukadaulo wopanga, zofunikira zaukadaulo pansalu zopanda madzi komanso zopumira ndizokwera kwambiri kuposa zansalu zosalowa madzi; Pa nthawi yomweyi, ponena za ubwino, nsalu zopanda madzi ndi zopumira zimakhalanso ndi ntchito zomwe nsalu zina zopanda madzi zilibe. Nsalu zopanda madzi ndi zopumira sizimangowonjezera mpweya ndi madzi a nsalu, komanso zimakhala ndi mpweya wapadera. Amatha kutulutsa msanga mpweya wamadzi mkati mwa kapangidwe kake, kupewa kukula kwa nkhungu, ndikusunga thupi la munthu louma nthawi zonse. Amathetsa bwino mavuto a kupuma, kukana mphepo, kutsekereza madzi, ndi kutentha, kuwapanga kukhala mtundu watsopano wa nsalu zathanzi komanso zachilengedwe.
matiresi ndi chinthu chofunika kwambiri pa moyo wathu watsiku ndi tsiku. Ngati pali ana omwe ali okangalika kunyumba, mungaganizire kugula matiresi opangidwa ndi nsalu yopanda madzi kuti mugwiritse ntchito kumbuyo, zomwe zingachepetse mavuto ambiri m'moyo wanu.
Momwe mungathamangitsire madzi
1. Chilinganizo cha Yang
Dontho lamadzimadzi limagwera pamalo olimba, poganiza kuti pamwamba pake ndi bwino lathyathyathya, mphamvu yokoka ya dontho imayikidwa pamlingo wina, ndipo kuchuluka kwake m'munda kumanyalanyazidwa. Chifukwa cha kuyanjana pakati pa zovuta zapamtunda (Ys) za ulusi pansalu, kuthamanga kwamadzi (YL) kwamadzimadzi, ndi kusagwirizana kwapakati (YLS) kwa zomangira, madontho adzapanga maonekedwe osiyanasiyana (kuchokera ku cylindrical mpaka ku lathyathyathya kwathunthu). Pamene dontho lamadzimadzi limakhala lofanana pamtunda wolimba, mfundo A imakhudzidwa ndi mphamvu yokoka yobalalika, kupatula kukhazikika kwathunthu.
Ngodya 0 imatchedwa ngodya yolumikizana, Pamene 0= Pa 00 koloko, dontho lamadzimadzi limanyowetsa pamwamba pa nsalu ya thonje, yomwe ndi malire a malo olimba omwe amanyowetsedwa ndi munda. Pamene 0=1800, dontho lamadzimadzi limakhala lozungulira, lomwe ndi malo abwino osanyowa. Pomaliza kuthamangitsa madzi, kuthamanga kwamadzi kwamadzi kumatha kuonedwa ngati kosalekeza. Choncho, ngati munda akhoza kunyowetsa olimba pamwamba ndi wofanana ndi kukanikiza anapatsirana akufa lotus tsamba pa olimba pamwamba pa banki. Amanenedwa kuti mbali yayikulu yolumikizirana ya 0 ndi yabwino kwambiri pakutayika kwa dontho lamadzi lamadzi, zomwe zikutanthauza kuti yaying'ono ndi yabwinoko.
2. Ntchito yomanga nsalu
Chifukwa chakuti Ys ndi YLS sizingayesedwe mwachindunji, ngodya yolumikizana 0 kapena cos0 nthawi zambiri imagwiritsidwa ntchito kuyesa mwachindunji kuchuluka kwa kunyowetsa. Komabe, kukhudzana ngodya si chifukwa kunyowetsa, ndipo zotsatira zenizeni ndiye chizindikiro chomwe chimaimira ntchito yomatira ndi kugwirizana pakati pawo, komanso mlingo wa kunyowa.
Onse YL ndi cos0, omwe amaimira ntchito zomatira, amatha kuyeza, kotero equation ili ndi tanthauzo lenileni. Momwemonso, ntchito yofunikira kugawa dontho lamadzi pagawo lililonse pamawonekedwe kukhala madontho awiri ndi 2YL, yomwe ingatchulidwe ngati ntchito yolumikizana yamadzimadzi. Kuchokera pamapangidwewo, zitha kuwoneka kuti ntchito yomatira ikamakula, mbali yolumikizana imachepa. Pamene ntchito yomatira ili yofanana ndi ntchito yogwirizana, ndiko kuti, mbali yolumikizana ndi zero. Izi zikutanthauza kuti madziwo ndi flattened pa olimba pamwamba. Popeza cos0 sichitha kupitirira 1, ngakhale ntchito yomatira itakhala yayikulu kuposa 2YL, mawonekedwe olumikizana amakhala osasinthika. Ngati WSL = ”YL, ndiye 0 ndi 900. Pamene kukhudzana ngodya ndi 180 °, WSL = O, kusonyeza kuti palibe viscous zotsatira pakati pa madzi ndi olimba Komabe, chifukwa cha zomatira zotsatira pakati pa zigawo ziwiri, mmene kukhudzana ngodya ndi wofanana 180 ° sichinayambe anapezeka, ndipo makamaka, ena okha pafupifupi 1 kapena 60 mikhalidwe pafupifupi 60.
3. Kuvuta kwambiri kwapamwamba kwa nsalu
Chifukwa cha kuyeza kosatheka kwa kugwedezeka kolimba pamwamba, kuti amvetsetse kunyowa kwa malo olimba, wina adayesa kugwedezeka kwake kwakukulu. Ngakhale kugwedezeka kwakukulu kwapamwamba sikungathe kuyimira mwachindunji kugwedezeka kwapamwamba kwa olimba, koma kukula kwa Ys YLS, kungasonyeze kuvutika kwa kunyowetsa pamwamba pa olimba. Koma ziyenera kukhala
Zindikirani kuti kuyeza kugwedezeka kwakukulu kwapamwamba ndi njira yowonetsera ndipo miyeso ya muyeso ndi yopapatiza kwambiri.
Zitha kuwoneka kuti kupatula pa cellulose, kupsinjika kwakukulu kwa zinthu zonse kumakhomeredwa kukhala otsika, kotero onse amakhala ndi gawo lina la kuthamangitsa madzi, pomwe CF3 imakhala yayikulu kwambiri ndipo CH imakhala yaying'ono kwambiri. Mwachiwonekere, mpando uliwonse wakuthupi wokhala ndi kukhudzana kokulirapo komanso kupsinjika kwakung'ono kwapamtunda, komanso wothandizira aliyense womaliza, amatha kupeza zotsatira zabwino zothamangitsa madzi.
