Hygroscopicity - izo ... hygroscopicity ulusi, zovala

Ine ndikutsimikiza ambiri mawuwo ndipo mwina ngakhale sankadziwa mmene kwalembedwa ndi tanthauzo lake. Koma si aliyense amadziwa chakuti chidziwitso cha thupi katundu zipangizo zingakhale zothandiza pa moyo watsiku ndi tsiku. Ndicho chifukwa ife timudziwe bwino.

tanthauzo

Hygroscopicity - katundu uyu chuma chilichonse kuyamwa ndi kusunga chinyezi mpweya. Ena angasokonezeke kalata "g" mu gawo loyamba la mawu, chifukwa ife tonse tikudziwa kuti mawu zovuta kugwirizana ndi madzi ndi zambiri kuyamba ndi manambala oyambirira "hydro". Koma pano ndi pang'ono chinachakenso. Hygroscopicity limalola mayamwidwe zipangizo uli ndi madzi amene sprayed mu mlengalenga ngati utsi, wakuoneka choncho afunika chosiyana kupatula pamwamba bokosi. "Hygro" zikutanthauza kuti mawu ofanana ndi chinyezi. Ndi yosavuta.

Tinakambirana tanthauzo, ndipo tsopano ndi nthawi kuti tipeze chimene chiri mawu njira. The mumpweya ali ndi ena mnyontho - akulankhula za iyo, ngakhale odziŵa za nyengo. Ena ulusi amatha kuyamwa madzi atero pafupipafupi kusintha katundu wake. Ndi chifukwa zovala hygroscopic ndi nsapato mwina zisanyowe ngakhale popanda mvula. Nthawi zina, ndi bwino, nanga - zoipa, kuphunzira pansipa.

Kodi zipangizo ndi hygroscopic?

M'nkhaniyi tiona zimakhala ndi. Koma osati akhoza kuyamwa chinyontho mpweya. Hygroscopicity index zakuthupi kaŵirikaŵiri kofunika kudziwa omanga nyumba, opanga mipando, opanga zipangizo zovuta ndi ena ambiri.

Mwachitsanzo, ife tonse tikudziwa kuti mitengo ali ndi dongosolo porous, izo kumawonjezera katundu hygroscopic. Madzi ozama mu kapangidwe nkhuni deforms izo. N'chifukwa chake nkhuni mipando ndi pafupifupi anaika mu zipinda ndi chinyezi mkulu. impregnation Special zingagwiritsidwe ntchito pofuna kuchepetsa hygroscopicity.

N'kofunika, ndi katundu hygroscopic wa kutchinjiriza ntchito pomanga. Mpweya atsekerezedwa mu pores zakuthupi amasunga kutentha mu chipinda. Koma ngati kutchinjiriza afika yamvula yomweyo wotaya katundu wofunikira. Choncho, zipangizo ntchito imeneyi ayenera kukhala osachepera madzi mayamwidwe. ganizoli 0%.

Ukhondo katundu wa nsalu

zipangizo zonse ndi magawo osiyana thupi monga osalimba, mphamvu etc. Koma nsalu, amene kenako kwa n'kukhala zinthu ndi zovala ndi zina zofunika - ukhondo. Iwo kudziwa omasuka kuvala ku nkhani ina.

• Breathability. Dzinali odziwikiratu. Nsalu ndi breathability mkulu amatha "kupuma", ndi otsika - chitetezo mphepo.
• The nthunzi ya madzi permeability. Luso pochitika chinyezi kuchokera nsalu kutenga cholinga thukuta ndi madzi ena a m'thupi.
• Madzi. Kumatetezera thupi ku zakumwa. Mbali imeneyi kumawonjezera minofu mwa mankhwala osiyanasiyana padziko ndi zokutira.
• Pyleomkost. Mbali imeneyi zimathandiza nsalu kusunga particles bwino pamwamba pake. The boleematerial lotayirira, ndi apamwamba a pyleomkosti.

• Inasangalatsa - luso minofu kudziunjikira magetsi malo amodzi.

Musaiwale za katundu kutentha kutetezedwa kwa minofu. Luso limeneli kukhalabe kutentha yachibadwa thupi pa nthawi imene kukuzizira kunja. Ndipo pa malo otsiriza tikambirana mwatsatanetsatane.

nsalu hygroscopicity

chithunzi zikugwirizanirana katundu ukhondo wa zovala, limene pamapeto kudziwa chitonthozo cha nkhani ina pamene ankavala. Komanso amafuna kuti zovala mwachuluka amadalira cholinga chake.

Hygroscopicity - ndi katundu wofunika kwambiri olimba kapena yotentha zovala. Kuchuluka thupi kutentha ndipo kumayambitsa thukuta kwambiri, womwe amalenga mavuto osiyanasiyana kwa munthuyo. Tayani chinyezi owonjezera chololera mkulu hygroscopic nsalu. Mundawu ndi chizindikiro zofunika alimi a kabudula wa tsiku ndi tsiku.

Kodi Mzimuyo luso nsalu kuyamwa chinyontho kwa chilengedwe? Mu malo oyamba - kuchokera ulusi umene anapanga. Komanso, kufunika ndi kukhalapo kwa zokutira kumatenda ndi kukupatsidwa mimba.

Mitundu ndi ulusi hygroscopic

Zipangizo za amene anapanga nsalu kuti inayamba osiyana. Pali ulusi zachilengedwe ndi kupanga. Choyamba, tiyeni tikambirane za poyamba. Iwo analengedwa ndi chikhalidwe, ngakhale popanda munthu.

Ubweya kusengedwa kwa nyama zosiyanasiyana, nthawi zambiri ntchito yopanga zovala zotentha. Kuti ali mmodzi wa ŵa nsalu chibadwidwe luso kuyamwa chinyontho. Hygroscopicity ubweya ulusi ndi za 15-17%. Koma pano pali madzi mlingo mayamwidwe ndi wotsika.

chithunzi Ichi ndi apamwamba kwambiri kuposa zimakhala zina zambiri. Mwachitsanzo, hygroscopicity thonje ndi 8-9 kokha%, koma akhoza kuyamwa chinyontho mofulumira kwambiri ubweya. Nsalu zina zachilengedwe - fulakesi kuwapeza CHIKWANGWANI bast. umatha kuyamwa chinyontho akhoza zimasiyana 12 kufika 30%.

Amapanga ndi kupanga ulusi

Yoyamba zikuphatikizapo zipangizo anachokera ku mankhwala achilengedwe. A chitsanzo chapadera - viscose. Iwo analengedwa ntchito mapadi achilengedwe. Pakuti ulusi viscose yodziwika ndi mphamvu, kutentha kukana, komanso mkulu hygroscopicity, wofanana pafupifupi 40%.

Kupanga ulusi kupanga mafuta kuyenga ndi malasha. Zikuphatikizapo polyamides. Ulusi izi kubala nayiloni, nayiloni ndi anide. Hygroscopicity wa zomangira ndi otsika kwambiri, 3-4 kokha%, koma kusunga mphamvu zawo pamene anatambasula ndi cholimba kwambiri. Poliyesitala ulusi umene kulenga poliyesitala nsalu, mkulu index kukaniza kutentha ndi kuwala fastness. Koma hygroscopic awo kochepa - 0.4 okha%.

Spandex, maziko Lycra ndi Spandex komanso yodziwika ndi luso kuyamwa chinyontho kwa chilengedwe. Kuchokera pamwamba Ndizachidziwikire kuti absorbability zovala zopangidwa angapange kwambiri m'munsi kuposa zimene anapanga nsalu achilengedwe. Koma ichi kwenikweni sangathe?

Hygroscopicity - ndi wabwino kapena woipa?

Ndi wachibale onse. The Tinganenenso chimodzimodzi nkhani analeredwa ndi ife. Sangathe kunena kuti hygroscopic - ndizabwino. Inde, timatha anthu kosavuta kuti apulumuke kutentha, ndi akatswiri - kuchita kokoka malo bwino kwambiri. Koma ena zimakhala chinyezi kwambiri zitha wavulala.

Pa chitsanzo cha chotenthetsera, ife tapeza kuti madzi amachepetsa katundu chimateteza zipangizo. Komanso, zimakhala ndi olumala mchikakamizo cha chinyezi - ife tonse tikudziwa mmene kutambasula yunifomu pambuyo kusamba. Tsoka imodzi, Pamlingo wamng'ono, amavutika ena zipangizo pa lalitali kwambiri chinyezi wachibale. Choncho Sizotheka kunena motsimikiza kuti hygroscopic nsalu - kuti ndi mwayi. Funso mathero a nkhani ina.

Kodi kudziwa chithunzi ichi?

Mu 80 ntchentche wa XX atumwi ku Soviet Union izo analengedwa ndi GOST 3816-81. Imakhala nkhani ya njira mtima wa ena katundu nsalu kuphatikizapo hygroscopicity. Apa ndi momwe iyo yachitira.

Akatswiri mumtengo masentimita 5x20 kukula ndipo aliyense minofu anaikidwa mu osiyana galasi masekeli. Ntchito yaikulu ya kuyesera - kupeza momwe madzi kuchuluka kuyamwa mfundo zomwe zili pa zinthu zina. Chifukwa chaichi, chikho chitsanzo anaikidwa mu desiccator imene chinyezi ndi ndi 97-99%. Pambuyo 4 chasa chitsanzo masekeli imagwiridwa, ndipo kenako pa kutentha ^pafupifupi 105-109 C, nkhani anauma ndi kudziwa kulemera watsopano.

Hygroscopicity index (H) mu kuchuluka anatsimikiza ntchito njira: N = (MB - Mc) / MS X 100, kumene MV ndi Mc kulandira, motero, kulemera kwa nsalu yonyowa ndi youma.
