Iko kushanduka kwemavara musimboti uye chimiro cheanodzorereka thermochromic pigments:
Thermochromic pigment imhando yemamicrocapsules anochinja ruvara kakawanda nekukwira kwekushisa kana kudonha.
Iyo inodzoreredzwa thermochromic pigment inogadzirwa kubva kune erekitironi yekufambisa mhando organic compound system.Electron transfer type organic compound imhando ye organic coloring system ine yakakosha kemikari chimiro.Pane imwe tembiricha, chimiro chemolecular ye organic substance inoshanduka nekuda kwekufambiswa kweelectron, nekudaro kuona shanduko yeruvara.Ichi chinoshandura ruvara hachina kupenya chete muvara, asi zvakare chinogona kuona shanduko yeruvara kubva ku "ruvara === isina ruvara" uye "ruvara === ruvara".Iyo inorema simbi yakaoma munyu yakaoma mhando uye liquid crystal mhando inodzoreredza tembiricha shanduko Izvo zvisina chinhu.
Iyo microencapsulated reversible thermochromic substance inonzi reversible thermochromic pigment (inowanzozivikanwa se: thermochromic pigment, thermopowder kana thermochromic powder).Zvimedu zvepigment iyi zvine denderedzwa, neavhareji dhayamita ye2 kusvika ku7 microns (micron imwe yakaenzana nechuru chemirimita).Mukati mune chinhu chinobvisa ruvara, uye kunze igoko rakajeka rinenge 0.2 ~ 0.5 microns gobvu risinganyungudike kana kunyungudika.Iyo ndiyo inodzivirira iyo discoloration substance kubva mukukukurwa kwemamwe makemikari zvinhu.Naizvozvo, zvakakosha kuti urege kukuvadza goko iri panguva yekushandiswa.
Kuchinja kwemavara tembiricha ye thermochromic pigment
1. Sensitive tembiricha shanduko yemavara tembiricha
Muchokwadi, tembiricha yekuchinja kwemavara ye thermochromic pigments haisi tembiricha, asi tembiricha yemhando, kureva, tembiricha yemhando (T0 ~ T1) inosanganisirwa kubva pakutanga kwekuchinja kwemavara kusvika kumagumo ekuchinja kwemavara.Kufara kwehasha ukuchiyero chechimiro chinowanzo 4 ~ 6℃.Mamwe marudzi ane hunyanzvi hwekusiyana kwemavara emhando yepamusoro (mhando dzakatetepa, dzinoratidzwa na "N") dzine tembiricha yakatetepa, chete 2 ~ 3.℃.
Kazhinji, isu tinotsanangura tembiricha T1 inoenderana nekupedzwa kwekuchinja kweruvara panguva yekugara tembiricha yekudziya maitiro sekushanduka kwemavara tembiricha ye thermochromic pigment.
2. Kutenderera nguva tembiricha kuchinja ruvara:
Tora zvishoma zvakaedzwa-mavara-kuchinja pigment, zvisanganise ne 504 epoxy glue, sveta sampuli (ukobvu 0.05-0.08 mm) pamapepa machena uye urege kumira panzvimbo yekushisa inopfuura 20 ° C kwezuva rimwe.Cheka pepa re 10 × 30 mm.Tora maviri 600 mL beakers uye uzadze nemvura.Tembiricha yemvura ndeye 5-20℃pamusoro pemuganho wepamusoro (T1) weiyo ruvara shanduko tembiricha yemhando yakaedzwa sampuli uye isiri pasi pe5℃pasi pemuganho wakaderera (T0).(Kune RF-65 yakatevedzana inki, tembiricha yemvura inoiswa seT0=35℃, T1=70℃.), uye chengetedza tembiricha yemvura.Sample inonyudzwa mumabheki maviri achichinjana, uye nguva yekupedzisa kutenderera kwega kwega masekonzi matatu kusvika mana.Tarisa shanduko yeruvara uye rekodha iyo inodzoserwa ruvara kutenderera nhamba (kazhinji, iyo ruvara shanduko kutenderera number ye thermal decolorization series yakakura kudarika 4000-8000 times).
Mamiriro ekushandiswa kwe thermochromic pigments:
Iyo inodzoreredzwa thermochromic pigment pachayo ndiyo isina kugadzikana sisitimu (kugadzikana kwakaoma kuchinja), saka mwenje wayo wekudzivirira, kupisa kupisa, kuchembera kuramba uye zvimwe zvimiro zvakaderera kune akajairwa pigment, uye kutarisisa kunofanirwa kubhadharwa mukushandiswa.
1. Kuramba kwechiedza:
Thermochromic pigments haina kusimba kwechiedza uye inokurumidza kupera uye kusashanda pasi pezuva rakasimba, saka inokodzera chete kushandiswa kwemukati.Dzivisa chiedza chezuva chakasimba uye ultraviolet chiedza, izvo zvichabatsira kuwedzera hupenyu hwemuvara-inoshandura pigment.
2. Kuramba kupisa:
Iyo thermochromic pigment inogona kumira tembiricha ye230℃munguva pfupi (anenge maminetsi gumi), uye inogona kushandiswa kuumba jekiseni uye kupisa kwakanyanya kupora.Nekudaro, kugadzikana kwekupisa kwemavara-anochinja pigment kwakasiyana muruvara-.kusimudzira nyika uye achromatic state, uye kugadzikana kweyekutanga kwakakwira kupfuura iyo yekupedzisira.Pamusoro pezvo, kana tembiricha yakwira kupfuura 80°C, iyo organic matter inoumba discoloration system inozotangawo kudzikira.Naizvozvo, mavara-anoshandura pigment anofanirwa kudzivirira kushanda kwenguva refu kune tembiricha inodarika 75°C.
Kuchengetedza kwe thermochromic pigments:
Ichi chigadzirwa chinofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye yakasviba zvachose.Sezvo kugadzikana kwemavara-anoshandura pigment mumamiriro ekukura-mavara akakwirira kudarika ari mu achromatic state, marudzi ane tembiricha yakaderera-inoshandura mavara anofanira kuchengetwa mufiriji.Pasi pemamiriro ezvinhu ari pamusoro apa, kuita kwemhando dzakawanda dzemavara-inoshandura pigments hakuna kunyanya kuderedzwa mushure memakore mashanu ekuchengetedza.
