Ipeni ekhawulezayo-yeDyne eyomileyo sisixhobo esibalulekileyo sokuvavanya ukuxinana komphezulu wemathiriyeli kwimizi-mveliso yokupakisha, yoshicilelo, kunye nokwaleka. Iziphumo ezingachanekanga zinokuchaphazela ngokuthe ngqo ukhetho lwenkqubo kunye nolawulo lomgangatho. Imiba engundoqo ijikeleza ikakhulu kwizinto ezine eziphambili, njengoko zichazwe ngezantsi
Ungcoliseko loMphezulu
Unobangela ongundoqo:Ungcoliseko kumphezulu wemathiriyeli kuthintela intsebenziswano ngqo phakathi kwe-inki kunye nomphezulu, okukhokelela kumaxabiso aphantsi alinganisiweyo. Imithombo ephambili yongcoliseko yile: i-oyile kunye nokubila kwiminwe yabaqhubi, eyenza ifilimu ebhityileyo kumphezulu wezinto eziphathekayo, kunye nothuli lokusingqongileyo kwiindibano zocweyo okanye iilebhu, ezibambelela kumphezulu kwaye zenze umqobo womzimba, ochaphazela ukufana kwe-inkino yokusabalalisa.
Isisombululo:Sebenzisa inkqubo yokucoca esemgangathweni{0}zosula umphezulu wemathiriyeli amaxesha 2-3 kwicala elinye usebenzisa ilinti{3}}ilaphu lasimahla elifakwe kutywala obuphezulu be-isopropyl okanye isicoci somphezulu esizinikeleyo. Emva kokusula, faka izinto kwindawo ecocekileyo kwaye uvumele i-solvent iqhume ngokupheleleyo. Nxiba umgubo{7}iglavu ze-nitrile zasimahla ngexesha lokusebenza ukuphepha ukunxibelelana ngqo nesandla kwindawo yovavanyo kwaye uthintele ungcoliseko lwesibini.
Pen Tip Ukomisa
Unobangela ongundoqo:I-Evaporation ye-solvent ye-inki ibangela ukuxininisa okunyukayo, ukunciphisa umbane, kunye nokuvala, okukhokelela kwimiba efana nemigca ephukileyo ngexesha lokufaka isicelo kunye nokusabalalisa kwe-inki okungaqhelekanga, okunokubangela ukugwetywa kakubi. Izinto ezibangela okuqhelekileyo ziquka ukusilela ukuvala ngokuqinileyo ipeni phakathi kovavanyo okanye ugcino olungafanelekanga (ukungayigcini iguqulwe okanye ithe tyaba njengoko kufuneka).
Isisombululo:Ukomisa kancinci, cofa ngokuthe nkqo incam yosiba kwilinti ecocekileyo{0}iphepha lasimahla kwaye ngobunono uzobe imigca emi-2–3 ukukhupha i-inki entsha. Ukuba incam yomile okanye ivalekile, buyisela ipeni kwangoko{4}}ungazongezi ezinye izinyibilikisi, kuba oku kunokutshintsha ukuxinana kwe-inki. Emva kokusetyenziswa kwemihla ngemihla, hlala uyivala ngokuqinileyo ipeni kwaye uyigcine iguqulwe ukuze ugcine incam ifumile. Gcina ipeni kude nemithombo yobushushu kunye nokuhamba komoya okuqinileyo.
Ukufuma kokusingqongileyo
Unobangela ongundoqo:Xa ukufuma okuhambelanayo kudlula i-80%, ukufuma kuphazamisa iziphumo ngeendlela ezimbini: okokuqala, "ifilimu yamanzi" ifom kumphezulu wezinto ze-polar (umzekelo, inayiloni okanye i-PET), ukuphucula i-polarity kunye nesiphumo sokulinganisa amaxabiso aphezulu; okwesibini, i-inki ifunxa ukufuma kwaye iyancipha, ngakumbi ichaphazela iipens ezisezantsi{3}} (umzekelo, 30-36 mN/m), ezikhokelela ekugwetyweni kakubi ngenxa yokusabalalisa okugqithisileyo.
Isisombululo:Ngokufanelekileyo, gcina indawo yovavanyo kwi-23±2 idigri kunye nokufuma okuhambelana ne-50±5% RH usebenzisa iqondo lokushisa kunye negumbi lokufuma. Ukuba ulawulo lokusingqongileyo alufumaneki -kwisiza, lungisa zombini izinto kunye nepeni yeDyne kwindawo esemgangathweni ubuncinane iiyure ezi-2 phambi kovavanyo. Uvavanyo lwenziwa kude nemithombo yamanzi, kwaye urekhode iqondo lobushushu kunye nokufuma ukulungiselela ireferensi yexesha elizayo.
Iimpawu zeMathiriyeli
Iimpawu zendalo zemathiriyeli ezahlukeneyo zichaphazela ukusebenza kovavanyo kwaye zifuna iindlela ezilungiselelweyo:
Iimathiriyeli ezirhabaxa (umzekelo, iphepha, ilaphu, iiseramikhi ezinabileyo): I-inki ingena ngokukhawuleza kwi pores, yenze ukuba kungenzeki ukujonga indlela yokuziphatha "yekhontrakthi/{2}}engabotshwanga, nto leyo edla ngokukhokelela kwizigwebo ezibubuxoki "zoxinzelelo olunganelanga" okanye iziphumo zobuxoki.
Isisombululo:Sebenzisa iipeni zeDyne ezikhethekileyo -ezinokufikeleleka eziqulethe izinto ezichasene{1}}nentlaka yokungena. Ngaphambi{3}}yomisa imathiriyeli kwi-oven eyi-80 imizuzu engama-30 kwaye iphole kwiqondo lobushushu begumbi phambi kovavanyo.
Iimathiriyeli zeHygroscopic (umzekelo, iNayiloni 6, ifayibha yeacetate, iinkuni): Ezi zixhobo zifunxa ngokulula ukufuma okuvela emoyeni, zikhulisa ipolarity yomphezulu kunye namaxabiso alinganisiweyo. Iziphumo ziguquguquka kakhulu njengoko amaxabiso ebuyela kwesiqhelo emva kokoma.
Isisombululo:Sebenzisa ukufuma-ukuphazamiseka{1}}kweepeni zeDyne ezinganyangekiyo ezinezinyibilikisi ze-inki ezingaxubeki lula namanzi. Lungiselela imathiriyeli kwindawo eyomileyo (<30% RH) for at least 4 hours before testing. Select 3–5 test points on different areas of the material and use the average value as the final result to minimize deviations caused by material inhomogeneity.
Isishwankathelo
Ukuqinisekisa iziphumo zovavanyo olukhawulezayo-olulomileyo lweDyne, qwalasela imiba emine engundoqo: ulawulo lwendalo esingqongileyo, ukuphathwa kwangaphambili kwemathiriyeli, imigangatho yokusebenza, kunye{1}}nohlobo oluhambelanayo nosiba. Dibanisa ezi kunye neenkqubo zokusebenza ezisemgangathweni. Beka phambili ukulungisa imiba elawuleka lula njengokungcoliseka komphezulu kunye nencam yencam yosiba, emva koko ujongane nokusingqongileyo kunye nezinto ezinxulumene{4}}nemiba. Le ndlela inciphisa ngokusebenzayo ukutenxa kwaye ibonelela ngedatha ethembekileyo yenkqubo yokwenza izigqibo{6}}.
