Umgomo wokushintsha umbala wemibala eshintshayo ye-thermochromic yezinkomishi

Umgomo wokushintsha umbala kanye nesakhiwo sokushintshashintsha kwezibala ze-thermochromic:

I-Thermochromic pigment iwuhlobo lwama-microcapsules ashintsha umbala ngokuphindaphindiwe ngokwenyuka kwezinga lokushisa noma ukuwa.

I-pigment ye-thermochromic ehlehliswayo ilungiswa kusuka ohlelweni lwe-organic compound yokudlulisa uhlobo lwe-electron.I-Electron transfer type organic compound iwuhlobo lwesistimu ye-organic coloring enesakhiwo samakhemikhali esikhethekile.Emazingeni okushisa athile, ukwakheka kwamangqamuzana ezinto eziphilayo kuyashintsha ngenxa yokudluliswa kwe-electron, ngaleyo ndlela kuqaphele ukushintsha kombala.Le nto eshintsha umbala ayigcini nje ngokugqama ngombala, kodwa futhi ingabona ukushintsha kombala kusukela kusimo "sombala === ongenambala" kanye "nombala === onemibala".Iwuhlobo oluyinkimbinkimbi yensimbi eyinkimbinkimbi kanye nohlobo lwekristalu oluwuketshezi olushintshayo lokushisa Lokho into engenakho.

I-microencapsulated reversible thermochromic substance ibizwa ngokuthi i-reversible thermochromic pigment (evame ukwaziwa ngokuthi: i-thermochromic pigment, i-thermopowder noma i-thermochromic powder).Izinhlayiya zale pigment ziyindilinga, ezinobubanzi obuphakathi kwama-microns angu-2 kuya kwangu-7 (i-micron eyodwa ilingana nengxenye yenkulungwane yemilimitha).Ingaphakathi liwugqinsi olushintsha umbala, kanti ingaphandle liyigobolondo elisobala elingamamicrons angu-0.2~0.5 elingancibiliki noma lincibilike.Yiyo evikela into eshintsha umbala ekugugulekeni kwezinye izinto zamakhemikhali.Ngakho-ke, kubaluleke kakhulu ukugwema ukulimaza leli gobolondo ngesikhathi sokusetshenziswa.

Ukushintsha kwezinga lokushisa lombala we-thermochromic pigment

1. Izinga lokushisa elizwelayo lishintsha izinga lokushisa lombala

Eqinisweni, izinga lokushisa lokushintsha umbala we-thermochromic pigments akuyona indawo yokushisa, kodwa izinga lokushisa, okungukuthi, izinga lokushisa (T0 ~ T1) elifakiwe kusukela ekuqaleni kokushintsha kombala kuze kube sekupheleni kokushintsha kombala.Ububanzi balo msindoububanzi bemvelo ngokuvamile bungu-4 ~ 6℃.Ezinye izinhlobo ezinokunemba okuphezulu kokushintsha kombala (izinhlobo zebanga elincane, ezichazwa ngokuthi “N”) zinebanga lokushisa eliwumngcingo lokushintsha umbala, kuphela 2~3℃.

Ngokuvamile, sichaza izinga lokushisa elingu-T1 elihambisana nokuqedwa koshintsho lombala phakathi nenqubo yokushisa engaguquki njengezinga lokushisa elishintsha umbala we-thermochromic pigment.

2. Izikhathi zomjikelezo wombala wokushintsha kwezinga lokushisa:

Thatha inani elincane elihloliwe le-pigment eshintsha umbala, uyixube ne-504 epoxy glue, usule isampula (ubukhulu obungu-0.05-0.08 mm) ephepheni elimhlophe bese uliyeka lime ekamelweni lokushisa elingaphezu kuka-20 ° C usuku olulodwa.Sika iphethini yephepha engu-10×30 mm.Thatha ama-beake amabili angu-600 mLrs futhi uwagcwalise ngamanzi.Izinga lokushisa lamanzi ngu-5 ~ 20℃ngaphezu komkhawulo ongaphezulu (T1) webanga lokushisa elishintsha umbala wesampula elihloliwe futhi elingekho ngaphansi kuka-5℃ngaphansi komkhawulo ophansi (T0).(Ngoyinki wochungechunge lwe-RF-65, izinga lokushisa lamanzi libekwe njenge-T0=35℃, T1=70℃.), futhi ugcine izinga lokushisa lamanzi.Isampula icwiliswa kumabhekha amabili ngokulandelana, futhi isikhathi sokuqeda umjikelezo ngamunye amasekhondi angu-3 kuya kwangu-4.Bheka ukushintsha kombala bese urekhoda inombolo yomjikelezo wombala obuyisele emuva (imvamisa, umjikelezo wokushintsha umbalaI-mber yochungechunge lwe-thermal decolorization inkulu kunezikhathi ezingama-4000-8000).

Imibandela yokusetshenziswa kwezibala ze-thermochromic:

I-pigment eguquguqukayo ye-thermochromic ngokwayo iyisistimu engazinzile (ukuzinza kunzima ukushintsha), ngakho ukumelana kwayo nokukhanya, ukumelana nokushisa, ukumelana nokuguga nezinye izakhiwo ziphansi kakhulu kune-pigments evamile, futhi ukunakwa kufanele kukhokhwe ekusebenziseni.

1. Ukumelana nokukhanya:

Izingulube ze-Thermochromic azikwazi ukumelana nokukhanya okungalungile futhi zizofiphala ngokushesha futhi zibe ezingavumelekile ngaphansi kokukhanya kwelanga okunamandla, ngakho zilungele ukusetshenziswa endlini kuphela.Gwema ukukhanya kwelanga okunamandla nokukhanya kwe-ultraviolet, okuzosiza ukunweba impilo ye-pigment eshintsha umbala.

2. Ukumelana nokushisa:

I-pigment ye-thermochromic ingamelana nezinga lokushisa eliphakeme lama-230℃ngesikhathi esifushane (cishe imizuzu eyi-10), futhi ingasetshenziselwa ukubumba umjovo kanye nokwelapha izinga lokushisa eliphezulu.Kodwa-ke, ukusimama kokushisa kombala oshintsha umbala kuhlukile kumbala-isimo esithuthukayo kanye nesimo se-achromatic, futhi ukuzinza kwangaphambili kuphakeme kunaleso sakamuva.Ukwengeza, lapho izinga lokushisa lingaphezu kuka-80°C, izinto eziphilayo ezakha uhlelo lokushintsha umbala nazo zizoqala ukuwohloka.Ngakho-ke, ama-pigments ashintsha umbala kufanele agweme ukusebenza isikhathi eside emazingeni okushisa angaphezu kuka-75°C.

Ukugcinwa kwezibala ze-thermochromic:

Lo mkhiqizo kufanele ugcinwe endaweni epholile, eyomile futhi emnyama ngokuphelele.Njengoba ukuzinza kwe-pigment eshintsha umbala esimweni sokuthuthukisa umbala kuphakeme kunaleyo esesimweni se-achromatic, izinhlobo ezinezinga lokushisa eliphansi elishintsha umbala kufanele zigcinwe efrijini.Ngaphansi kwezimo ezingenhla, ukusebenza kwezinhlobo eziningi zombala oshintsha umbala akuzange kwehliswe kakhulu ngemva kweminyaka engu-5 yokugcina.
