3. tus yam ntxwv ntawm tus number case
Ink yog ib qho muab tshuaj nplaum nrog rau ib yam khoom ntawm fluidity. Viscosity, yield yield, thixotropy, fluidity, thiab ziab tag nrho txiav txim siab kev ua tau zoo ntawm tus number case.
Peb yog ib lub lag luam loj hauv Shenzhen Tuam Tshoj. Peb muab txhua phau ntawv nthuav tawm, cov duab thaij duab, cov duab kos duab, cov tsiaj ntawv, lub thawv ntawv, daim ntawv qhia hnub, txhua yam ntawm PVC, cov khoom ntawv, ntawv sau, Cov menyuam phau ntawv, cov ntawv nplaum, txhua yam ntawv tshwj xeeb xim xim luam ntawv, daim card cardand li.

Viscosity: Lub vaj tse uas ua rau cov dej ntws tsis txaus. Nws yog ib qho kev ntsuas ntawm lub peev xwm ntawm cov kua nruab nrog ib leeg thiab tsim teeb meem rau lawv cov kev sib raug zoo ntawm cov khoom muaj nyob rau ntawm cov roj molecules, uas yog, qhov tsis haum rau cov kua dej. Lub xauv npo ntawm tus cwj pwm txuam nrog rau kev hloov ntawm tus cwj mem nyob hauv tus txheej txheem luam ntawv, qhov xwm txheej thiab cov ntawv ntawm daim ntawv, tus viscosity ntawm tus cwj mem yog loj dhau, kev hloov ntawm tus cwj mem thaum lub sij hawm luam ntawv tsis yooj yim rau kev siv, thiab qhov tshwm sim ntawm rub tawm hauv daim ntawv tshwm sim, ua luam ntawm daim ntawv luam tawm; tus viscosity yog tsawg heev. Duav yog yooj yim rau emulsify, qias neeg, cuam tshuam qhov zoo ntawm cov teeb meem luam tawm. Cov uas yuav tsum tau ua rau ntawm tus cwj pwm ntawm cov ntawv luam ntawm cov ntawv luam ntawm cov ntawv luam ntawm cov ntawv luam ntawm cov ntawv xov xwm, thiab kev hloov hauv qhov kub thiab txias.
Tawm los ntawm tus nqi: hais txog qhov tsawg kawg nkaus kev nyuaj siab yuav tsum pib dej ntws. Yog hais tias tus lej muab tawm ntawm tus nqi loj dhau lawm, nws yuav tsis yooj yim thiab nws yuav tsis yooj yim qhib. Yog hais tias tus nqi yield yog dhau me me, cov dots thaum lub sij hawm ntawm luam ntawv yuav yooj yim pib halo thiab ua rau cov teeb meem luam tawm tsis paub. Qhov luaj li cas ntawm cov khoom muaj nqis muaj feem xyuam rau tus qauv ntawm tus cwj mem thiab nws muaj kev sib tw rau ntawm tus cwj pwm ntawm cov naj npawb. Nws yog qhov taw qhia tseem ceeb rau qhov zoo tshaj ntawm offset thiab gravure inks.
Thixotropy: Nws yog hais txog qhov tshwm sim uas tus ntiv tes tau pib los ntawm qhov kev txiav txim ntawm kev sib tov thaum tawm sab nraud qis, thiab txoj haujlwm qaum nres nres thiab txoj kev rov qab mus rau nws tus xeeb thawj. Vim yog lub thixotropy ntawm tus cwj pwm, tom qab tus cwj mem yog tig los ntawm cov ntawv luam tawm ntawm tus cwj mem zauv rau tus kheej, cov kua fluid tau nce, qhov ductility yog nce, thiab tus cwj pwm muab kis yooj yim dua; thaum tus number case yog xa mus rau ntawm daim ntawv luam tawm, sab nraud quab yuam yog poob lawm. Tus number case los ntawm lub nyias nyias thiab tsis ntim ib ncig, ua tus sau zoo. Yog hais tias tus thixotropy ntawm tus number case loj dhau, tus number case nyob rau hauv cov ciav cwj mem tsis yog yooj yim tig, uas cuam tshuam tus number case hloov ntawm tus cwj mem xaws.
Fluidity: hais txog tus cwj mem raws li nws tus kheej lub ntiajteb txawj nqhis, yuav ntws zoo li kua, los ntawm tus lej viscosity, yield yield thiab thixotropy txiav txim siab, tab sis kuj nrog cov kub yog txuas zoo sib xws. Tus cwj pwm ntawm tus cwj pwm muaj feem xyuam nrog seb tus cwj mem nchuav tau los ntawm lub ntim, muab pauv mus rau tus cwj mem kua ntiv tes rau ntawm tus xov tooj ntawm lub luam ntawv, ua kom pauv ntawm tus ciav cwj mem, zoo rau cov luam ntawv, xa mus rau luam phaj, thiab pauv. Nyob rau hauv substrate, nws kuj cuam tshuam cov nyhuv luam tawm.
Qhov ntev ntawm tus cwj pwm: hais txog qhov uas tus cwj mem yog thawj zaug kos rau hauv ib daim ntawv pov tseg tsis muaj kev tawg. Qhov ntev ntawm tus cwj mem muaj feem xyuam rau thixotropy, yield yield, thiab viscosity yas ntawm tus number case. Cov cwj mem xaws kua tooj liab yog ib tug cwj mem los ntawm kev luam ntawv zoo hauv kev lag luam luam tawm thiab ntawv luam ntawv. Nws yuav tsis ua rau muaj kev xoom cim rau hauv kev luam ntawv. Nyob rau tib lub sij hawm, tus number case txheej rau ntawm daim ntawv luam tawm yog qhov tseem ceeb thiab tuab. Qhov ntev ntawm tus cwj pwm yog ib txoj kev rau thaum ntsuas kev ua rau kev siv tus number case.
