Hygroscopicity - it ... iifayibha hygroscopicity, iimpahla

Ndiqinisekile abaninzi beva eli lizwi yaye mhlawumbi babezibuza kubhaliwe kwathiwa ngayo yaye oko kuthetha ntoni. Kodwa asinguye wonke umntu uyazi into yokuba ulwazi iimpawu ezibonakalayo zemathiriyeli kunokuba luncedo kubomi bemihla ngemihla. Yiyo ke loo nto siya simazi ngakumbi.

Hygroscopicity - le ipropathi yakhe nawuphi na izinto okutsala ukugcina ukufuma evela emoyeni. Abanye uyabaphazamisa unobumba "g" kwi inxalenye yokuqala ilizwi, kuba sonke siyazi ukuba imiqathango nzima enxulumene ngamanzi kwaye ngokuqhelekileyo aqala isimaphambili "hydro". Kodwa nantsi ke kancinci into enye. Hygroscopicity ivumela nokufunxwa kwizinto eziqulathe kuphela amanzi iinta- emoyeni njengoko umphunga, kwaye ke ngoko kufuneka ibhokisi iseti-top eyahlukileyo ngokupheleleyo. "Hygro" kuthetha ukuba ilizwi ihlobene ukufuma. Yinto elula.

Siye saxubusha inkcazelo, kwaye ngoku lixesha lokuba ukufumanisa ukuba yintoni na ngokwenene eli gama lithetha. Emoyeni ngeenxa zonke kuthi isiqulatho sokufuma ethile - sithetha ngayo, nkqu zesimo sezulu. Ezinye Imicu bayakwazi ukufunxa lo manzi ngaloo rhoqo ukutshintsha iipropati yayo. Oku kungenxa iimpahla hygroscopic kunye nezihlangu ukuze afumane manzi ngaphandle kwemvula. Kwezinye iimeko, kulungile, yaye yintoni - embi, funda ngezantsi.

Ziziphi izinto hygroscopic na?

Kweli nqaku liza siya kugxininisa emzimbeni. Kodwa nje ukuba bayakwazi ukufunxa ukufuma evela emoyeni. Hygroscopicity index ye material kuyimfuneko rhoqo ukuze ukwazi abakhi, abenzi ifanitshala, kubavelisi izixhobo ezimbaxa kunye nabanye abaninzi.

Ngokomzekelo, sonke siyazi ukuba wood isakhiwo aneentunja, kwenyusa iimpawu zayo hygroscopic. Amanzi zingene isakhiwo iinkuni deforms kuyo. Kungenxa yoko le nto ifenitshala iinkuni Oku ifakelwe kumagumbi nokufuma eliphezulu. ukumitha Special ingasetyenziswa ukunciphisa hygroscopicity.

Kubalulekile, kwaye iimpawu hygroscopic ekwambathiseni asetyenziswe ekwakheni. Umoya ekwintunjana pores umbandela ugcina ubushushu egumbini. Kodwa ukuba yokugquma liba manzi, nto ngephanyazo ulahlekelwa iipropati yayo kubalulekile. Ngoko ke, izinto ezisetyenziselwa le njongo kufuneka abe ukufakwa kwamanzi ubuncinane. Umthetho-siseko kuku-0%.

iimpawu ucoceko yemeko

Zonke izinto zokuphila iparameters ezahlukeneyo, ezifana ukuxinana, amandla njl Kodwa amalaphu, ezo kamva ukuba zitshintshwe zibe izinto ngubo kunye nezinye iimpawu ezibalulekileyo - zisempilweni. Zimisela indlela ukhululekile ukuba banxibe ukusuka impahla ethile.

• Breathability. Igama uthetha ukuba ngokwayo. Amalaphu kunye breathability aphezulu ayakwazi "uphefumla", kwaye ephantsi - ukhuseleko umoya.
• Le umphunga wamanzi permeability. Ukukwazi Kwathi ukufuma ukusuka laphu athathe nenjongo ukubila kunye nezinye ulwelo emzimbeni.
• Manzi. Ikhusela umzimba ulwelo. Olu phawu kwandisa esikule ngokusebenzisa unyango kumphezulu ezahlukeneyo Coatings.
• Pyleomkost. Olu phawu ivumela laphu ukugcina amasuntswana omhle kumphezulu wayo. Ladlokova boleematerial, kungona pyleomkosti.

• Umbane - ukukwazi yethishyu ukuze yande umbane static.

Musa ukulibala malunga iipropati ubushushu-ayikhusele ngayo kwithishyu. Lo msebenzi ukugcina ubushushu bomzimba eqhelekileyo ngexesha xa kubanda phandle. Kwaye kwipropati ziza kuthetha ngakumbi.

hygroscopicity yengubo

Eli nani kunxulumene iimpawu wococeko eyolukiweyo, nto leyo ukumisela kuthuthuzelwa izinto ezithile xa zonakele. Ngaphezu koko, iimfuno bambathe lixhomekeke kakhulu injongo yayo.

Hygroscopicity - yeyona ndawo ibalulekileyo lokuphila okanye zasehlotyeni iimpahla. lobushushu emzimbeni Ukwanda kwaye ikhokelela ukubila ngokugqithisileyo, nto leyo idala nobunzima kakhulu ukuba umntu. Lahla ukufuma kwemfuneko kuvumela amalaphu phezulu hygroscopic. Lo mhlaba sisalathisi esibalulekileyo abavelisi kwempahla yangaphantsi ngemihla.

Yintoni ebonisa ukuba amandla ka laphu ukuba ukufunxa ukufuma-bume? Kwindawo yokuqala - ukusuka Imicu wona wenziwe. Ngaphezu koko, kubalulekile kuba phambi Ipeyinti zokuzikhusela impregnations.

Iindidi neefayibha hygroscopic

Izinto ezo ezenziwe ngelaphu, ukuze imvelaphi ezahlukeneyo. Kukho imicu zendalo kunye zokwenziwa. Okokuqala, makhe sithethe kuqala. Zidalwa ngokwemvelo, nangona ngaphandle koncedo lomntu.

Zoboya bezimvu ukusuka iintlobo zezilwanyana, amaxesha amaninzi kusetyenziselwa ukuvelisa iimpahla zobusika. Ukuba yenye yezinto eziphambili amalaphu zendalo ikhono lokunciphisa ukufuma. Imicu uboya Hygroscopicity imalunga 15-17%. Kodwa nantsi ukufuma njengeSpecific Absorption Rate liphantsi kakhulu.

Eli nani liphezulu kakhulu kunokuba kwezinye izicwili ezininzi. Umzekelo, hygroscopicity bomqhaphu yi 8-9% kuphela, kodwa iyakwazi ukufunxa ukufuma uboya ngokukhawuleza kakhulu. Enye izinto zendalo - iflakisi zingafumaneka ifayibha bast. ikhono layo ukufunxa ukufuma kunokwahluka ukusuka kwi-12 ukuya kuma-30%.

imicu Artificial and zokwenziwa

Uhlobo lokuqala luquka izinto ezivela iikhompawundi zendalo. A Umzekelo umxhelo - Viscose. Kubhaliwe wadala ngokusebenzisa neselulosi zendalo. Kuba kwimicu viscose luphawulwa ngamandla, ukumelana ubushushu, kananjalo hygroscopicity ophezulu, lingana ne ukuya phantse-40%.

imicu Synthetic ukudala iimveliso ze yokucokisa oyile kwakunye namalahle. Ezi ziquka polyamides. Kwezi okuzenzela ukuvelisa nenayiloni, nenayiloni kunye anide. Hygroscopicity of izinto ezifana kakhulu iphantsi,% 3-4 kuphela, kodwa abe namandla abo xa wolula kwaye ixesha elide kakhulu. Imicu ipholiyesta kuvule ipholiyesta ngelaphu, abe isalathiso ephezulu yokunganyangeki ubushushu kombala ukukhanya. Kodwa hygroscopic zabo minimal - 0.4% kuphela.

Spandex, inika isiseko ngeLayikhra kunye Spandex linophawu ikhono lokunciphisa komisa kokusingqongileyo. Ukusuka kungasentla kunokwenziwa isigqibo ukuba absorbability impahla ezenziwe zokwenziwa usezantsi kakhulu kwizinto ezenziwe amalaphu zendalo. Kodwa ngaba ngokwenene oku iyasokola?

Hygroscopicity - ngaba elungileyo okanye embi?

Kuxhomekeke isalamane. Kunjalo enokuthethwa mbandela ephakanyiswe yi kuthi. Umntu athi hygroscopic - kulungile. Ewe, kuba ivumela abantu lula ukuba asinde ubushushu, kunye neembaleki - ukwenza imithambo kwindawo bekhululekile ngakumbi. Kodwa ithishu ukufuma ngokugqithiseleyo kunokuba buhlungu kuphela.

Kulo mzekelo nehitha, siye safumanisa ukuba amanzi kunciphisa iimpawu zokwambathisa izinto. Ukongeza, ithishu ukuba gqitha phantsi kwempembelelo ubumanzi - sonke siyazi ukuba olule njani ijezi emva ukuhlanjwa. Efanayo, kuphela kangangoko encinane, ukuze eve ubunzima ezinye neemathiriyeli ukufuma eliphezulu kakhulu kwisalamane. Ngoko ke akusoloko kusenzeka ukuba sinokuqiniseka ukuba amalaphu hygroscopic - loo nto a plus. Lo mbuzo kwindawo kukho izinto ezithile.

Indlela ukujonga lo mzobo?

In-imi- 80 lwekhulu XX eSoviet Union yayiyilwe yi GOST 3816-81. Inika inkcazelo eneenkcukacha iindlela ukuze ukumiselwa ezithile iipropati textile kuquka hygroscopicity. Nantsi sokuba kwenziwe ngayo.

Iingcali iisampuli 5x20 cm ngobukhulu kunye zomzimba ngamnye ndafakwa eglasini eyahlukileyo ezikhathaza. Umsebenzi ophambili we-experiment - ukufumanisa ukuba amanzi aza ukufunxa umbandela phantsi kweemeko ezithile. Ukulungiselela le njongo, indebe isampuli yafakwa kwi desiccator apho i ukufuma yi 97-99%. Emva 4 chasa isampuli Ukuhlola yenzelwa, yaye emva koko xa amaqondo obushushu ^malunga 105-109 C, woma eziphathekayo isigqibo ubunzima yayo entsha.

indeksi Hygroscopicity (H) e ipesenti wagqiba usebenzisa ifomula: n = (MB - Mc) / Ms x 100, apho MV kunye Mc ngokufumana, ngokulandelelana, ubunzima amalaphu emanzi neyomileyo.
