Hygroscopicity - ke ... hygroscopicity endwangwini, izingubo

Ngithathe uqinisekile abaningi baye ezwa leli zwi futhi mhlawumbe ngisho wazibuza kulotshiwe kanjani nokuthi kusho ukuthini. Kodwa akubona bonke abaqaphelayo iqiniso lokuthi ulwazi izakhiwo ngokomzimba materials kungaba wusizo ekuphileni kwansuku zonke. Yingakho ukumazi kangcono.

definition

Hygroscopicity - lokhu impahla noma iyiphi impahla ukuncela nokugcina umswakama kusukela emoyeni. Abanye bangase ukudida uhlamvu "g" engxenyeni yokuqala yegama, ngoba sonke siyazi ukuthi imigomo kuyinkimbinkimbi elihlobene ne amanzi ngokuvamile siqale Isiqalo "Hydro". Kodwa nakhu kancane okunye. Hygroscopicity ivumela ukumuncwa izinto equkethe kuphela Amanzi wafutha emoyeni njengoba umusi, ngakho-ke badinga ehluke ngokuphelele ibhokisi set-top. "Hygro" kusho ukuthi igama li- okuhlobene nomswakama. Kulula.

Saxoxa definition, futhi manje sekuyisikhathi ukuthola ukuthi yini ngempela iyindlela izwi. Emoyeni osizungezile has a lomswakama ezithile - ukhuluma ngani, ngisho nesimo sezulu. Ezinye Imicu yotshani bayakwazi ukuncela lokhu amanzi ngaleyo ndlela njalo ishintsha izakhiwo zalo. Kuyinto ngenxa izingubo hygroscopic nezicathulo ungase uthole ezimanzi ngisho ngaphandle kwemvula. Kwezinye izimo, kukuhle, futhi kulokho - ezimbi, ufunde ngezansi.

Yini materials hygroscopic?

Kulesi sihloko sizogxila emisipheni. Kodwa hhayi kuphela bayakwazi ukuncela umswakama kusukela emoyeni. Hygroscopicity Inkomba elinama ngokuvamile kuyadingeka ukwazi abakhi, abenzi ifenisha, Abenzi imishini eyinkimbinkimbi kanye nabanye abaningi.

Ngokwesibonelo, sonke siyazi ukuthi ukhuni has a isakhiwo ukungena nakwamanye amazwe, it kwandisa impahla yayo hygroscopic. Amanzi engena phakathi isakhiwo ukhuni deforms ke. Yingakho ifenisha ukhuni cishe ukufakwa amakamelo nge umswakama high. impregnation Special ingasetshenziswa ukwehlisa hygroscopicity.

Ayikho ezingabalulekile kangako, kanti izakhiwo hygroscopic ukwahlukanisa ezisetshenziselwa ukwakha. Emoyeni sibhajwe ezimbotsheni okokusebenza igcina ukushisa egunjini. Kodwa uma ukwahlukanisa uthola ezimanzi, khona manjalo ilahlekelwa impahla yayo ebalulekile. Ngakho-ke, izinto asetshenziselwe le nhloso kufanele ibe namanzi ukumuncwa ubuncane. I okahle 0%.

izakhiwo zenhlanzeko lendwangu

Zonke izinto babe nemingcele ezahlukene somzimba, njengokushaya kwabantu, amandla, njll Kodwa izindwangu, okuyizinto kamuva kufanele iguqulwe ibe izinto ezihlobene ikhabethe kanye nezinye izakhiwo ezibalulekile - yokuhlanzeka. Yizo ezinquma ukuthi ukhululekile ukugqoka kusuka impahla ethile.

• Breathability. Igama liyazikhulumela. Kwangezikhathi nge breathability okusezingeni eliphezulu bayakwazi "ukuphefumula", kanye ongaphakeme - ukuvikelwa umoya.
• I permeability umhwamuko. Ikhono ukudlula umswakama indwangu ukuthatha aim umjuluko olunye uketshezi emzimbeni.
• Manzi. Kuvikela umzimba kusuka uketshezi. Lesi sici kwandisa nezicubu esebenzisa ebusweni ukwelashwa ahlukahlukene ezinengilazi.
• Pyleomkost. Lesi sici sivumela lendwangu ukugcina izinhlayiya emihle phezulu. I boleematerial okuxekethile, ayanda pyleomkosti.

• Gesi - ikhono kwezicubu buthelela zikagesi.

Ungakhohlwa mayelana izakhiwo ukushisa-ukuze sivikeleke ijwabu. Leli khono lokulondoloza ukushisa komzimba evamile ngesikhathi lapho kubanda ngaphandle. Futhi impahla lwakamuva bayoba ukukhuluma kabanzi.

hygroscopicity Indwangu

Lesi sibalo iphathelene izakhiwo zenhlanzeko nendwangu, nakho ukunquma induduzo impahla ethile nalapho igqoke. Ngaphezu kwalokho, izimfuneko izingubo incike injongo yawo.

Hygroscopicity - eka ebaluleke kakhulu ukuqina noma ehlobo izingubo. Ukwandiswa izinga lokushisa komzimba nokugeleza kuholela ukujuluka ngokweqile, nakho kudala ukungakhululeki esiningi umuntu. Lahla umswakama ngokweqile kuyivumela okusezingeni eliphezulu izindwangu hygroscopic. Le mpahla kuyinto kuyinkomba ebaluleke kubakhiqizi kwezingubo zangaphansi kwansuku zonke.

Yini enquma ikhono lendwangu ukuncela umswakama imvelo? Endaweni yokuqala - kusukela Imicu ngalo senziwa. Ngaphezu kwalokho, ukubaluleka kuba phambi ezinengilazi zokuzivikela futhi impregnations.

Izinhlobo yemisipha hygroscopic

Mathiriyeli okuyinto zenziwa lendwangu, kungase kudingeke zasezindaweni ezihlukahlukene. Kukhona Imicu yotshani yemvelo kanye zokwenziwa. Okokuqala nje, ake sixoxe kuqala. Kudaliwe ngokwemvelo, kodwa lithi akufanele ngaphandle kokuqondiswa umuntu.

Uvolo sheared kusuka ezihlukahlukene izilwane, kuvame kakhulu ukuba kusetshenziswe i-ukukhiqizwa nezambatho ezifudumele. Lokho-ke ingenye ehola izindwangu bemvelo ikhono lokunciphisa umswakama. Hygroscopicity uvolo Imicu yotshani imayelana 15-17%. Kodwa nakhu umswakama ukumuncwa rate kuqhathaniswa ongaphakeme.

Lesi sibalo siphezulu kunamanye kwamanye amathishu amaningi. Ngokwesibonelo, hygroscopicity zikakotini kuyinto% 8-9 kuphela, kodwa uyakwazi ukuncela umswakama uvolo isheshe. Enye indwangu yemvelo - yefilakisi eyatholakala kusukela fibre Bast. Amandla aso ungamunca umswakama ziyahlukahluka kusuka 12 kuya ku-30%.

Imicu yotshani Artificial and zokwenziwa

Uhlobo lokuqala kuhlanganisa izinto ethathwe compounds zemvelo. Isibonelo esimangalisayo - viscose. It is wadala ngokusebenzisa cellulose zemvelo. Ukuze i-viscose Imicu yotshani libhekene amandla, ukushisa ukumelana, futhi hygroscopicity okusezingeni eliphezulu, ilingana cishe u-40%.

nezindwangu zokwenziwa ukudala imikhiqizo ye uwoyela nokwenza amalahle. Lezi zihlanganisa polyamides. Of le micu ukukhiqiza inayiloni, inayiloni futhi anide. Hygroscopicity zezinto zokusebenza ezinjalo kuba ngempela ongaphakeme,% 3-4 kuphela, kodwa namandla abo lapho welulela futhi iqine kakhulu. Polyester Imicu yotshani zazo ukudala i-polyester Indwangu, abe Inkomba eliphezulu ukushisa ukumelana naso futhi kwenze fastness ukukhanya. Kodwa hygroscopic yabo sakugcina -% 0.4 kuphela.

Spandex, isisekelo Lycra futhi Spandex futhi libhekene ikhono lokunciphisa umswakama imvelo. Ngokwalokhu okungenhla kungenziwa baphetha ngokuthi absorbability ka izingubo ezenziwe zokwenziwa izinto kuyinto ephansi kakhulu kunalokho ngezinto ezenziwe izindwangu zemvelo. Kodwa lo ngempela kusimo?

Hygroscopicity - ingabe okuhle noma okubi?

Konke isihlobo. I Kungashiwo okufanayo mayelana kuncike ephakanyiswe yithi. Umuntu angekhe atjho ukuthi hygroscopic - kuhle. Yebo, evumela abantu kulula kusinde ekushiseni, nabagijimi - ukwenza izivivinyo endaweni ngokunethezeka. Kodwa ezinye izicubu umswakama ngokweqile kungakulimaza kuphela ubuhlungu.

On isibonelo heater, siye sathola ukuthi amanzi kunciphisa izakhiwo nangokuvikela materials. Ngaphezu kwalokho, ezinye izicubu kuthiwa zikhubazekile ngaphansi kwethonya umswakama - sonke siyazi kanjani yokwelula ijezi emva ukuwasha. Zabulawa, kuphela ngezinga elincane, bangase bahlupheke ezinye izinto ngesikhathi eliphezulu kakhulu umswakama isihlobo. Ngakho-ke akuyona njalo kungenzeka ukuba ngokuqiniseka ukuthi izindwangu hygroscopic - ukuthi i-plus. Umbuzo endaweni elinama ethile.

Indlela ukunquma lesi sibalo?

Ngo-80-yalolucwaningo ka XX leminyaka eSoviet Union ukuthi lwenziwe Yihhovisi GOST 3816-81. Linikeza incazelo eningiliziwe yezindlela ngenxa yokuzimisela kwezinye izakhiwo yendwangu kuhlanganise hygroscopicity. Nakhu ukuthi kwenziwa kanjani.

Ochwepheshe amasampuli 5x20 cm ubukhulu nezicubu ngamunye yafakwa ingilazi ahlukene enesisindo. Umsebenzi oyinhloko ukuhlolwa - ukuthola ukuthi amanzi angakanani ngeke amunca impahla ngaphansi kwezimo ezithile. Ngenxa yale njongo, indebe isampula yafakwa desiccator lapho nomswakama kuyinto 97-99%. Ngemva 4 chasa isampula enesisindo wenziwa, futhi ngemva kwalokho ezingeni lokushisa ^mayelana 105-109 C, okokusetshenziswa omisiwe futhi ukunquma isisindo sayo esisha.

Hygroscopicity Inkomba (H) kuphesenteji kunqunywa kusetshenziswa indlela: n = (MB - Mc) / Nksz x 100, lapho Mv futhi Mc ukuthola, ngokulandelana, isisindo izindwangu ezimanzi futhi omile.
