Cov duab sab nraud ntawm cov khoom muag tau dhau los ua qhov tseem ceeb hauv kev sib tw ua lag luam hnyav. Cov thawv xim tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ntim cov duab sab nraud ntawm cov khoom lag luam vim tias lawv cov khoom zoo, zoo nkauj thiab zoo nkauj tsos. Lub thawv xim tsis yog tsuas yog lub teeb yuag, yooj yim nqa, ntau yam khoom siv raw, tab sis kuj muaj kev tiv thaiv ib puag ncig zoo. Tam sim no cia's tham txog kev cuam tshuam ntawm tus cwj mem hloov ntawm kev luam ntawv hauv xim thawv luam ntawv?
Cov txheej txheem luam ntawv yog qhov ua tau ntawm tus lej hloov pauv. Feem ntau hais lus, tus number case hloov pauv ntawm offset luam ntawv yog qhov tsawg, txog 38%. Tom qab lub tshuab luam ntawv yog inked nrog daim pam, tus number case hloov pauv yog li ntawm 50%, thiab thaum daim pam hu rau daim ntawv, tus number case hloov pauv yog li 76%. Yog li ntawd, nws yog ib qho tseem ceeb heev los tswj tus nqi hloov ntawm tus number case. Ink haum, tus lej sib npaug, luam ntawv phaj, daim pam kev ua haujlwm, ntawv, tshuab luam ntawv, thiab lwm yam yuav cuam tshuam rau kev hloov ntawm tus number case.
Kev cuam tshuam ntawm tus cwj mem ua haujlwm ntawm tus cwj mem hloov
Ink nrog tsawg viscosity thiab siab fluidity yog ib qho yooj yim rau kev hloov thiab muaj kev hloov pauv siab; number case nrog viscosity siab thiab fluidity tsawg muaj qhov hloov pauv tsawg. Txhawm rau nce tus lej hloov pauv tus lej, viscosity thiab fluidity ntawm tus number case yuav tsum tau tswj. Kev ua haujlwm ntawm tus cwj mem kuj tseem yuav hloov nrog kev hloov ib puag ncig. Thaum qhov kub thiab txias, qhov viscosity ntawm tus number case yog qis, thiab thaum kub qis, qhov viscosity ntawm tus number case yog siab dua. Hauv kev tsim khoom tiag tiag, inks ntawm cov qauv sib txawv, hom thiab ntau txoj kev ziab yuav tsum raug xaiv raws li qhov xwm txheej tiag tiag. Tsis tas li ntawd, ntxiv qhov tsim nyog ntawm cov kua roj vanish rau tus number case tuaj yeem kho qhov kev ua tau zoo ntawm tus number case, uas yog qhov zoo rau kev tswj qhov nce hauv cov dots thiab txhim kho tus lej hloov pauv.
Qhov cuam tshuam ntawm daim pam kev ua tau zoo ntawm kev hloov tus number case
Daim pam yuav tsum muaj cov cwj mem zoo nqus thiab hloov cov cwj mem, nrog rau cov roj tsis kam, acid tsis kam, alkali tsis kam, thiab elasticity zoo. Yog tias daim pam tsis tau ntxuav kom huv si tom qab luam ntawv, tus number case khaws cia rau hauv lub fluff yuav maj mam harden lub conjunctiva, uas yuav ua rau lub fluff zoo li cov qauv ntawm cov roj hmab nto, uas ncaj qha cuam tshuam rau tus number case txais ntawm daim pam, yog li txo tus number case. hloov tus nqi ntawm daim pam. Yog li ntawd, tom qab luam ntawv, daim pam yuav tsum tau ntxuav kom huv si. Yog hais tias lub sij hawm downtime kuj ntev, ib txheej ntawm pumice hmoov tuaj yeem rubbed rau saum npoo ntawm daim pam kom tus qauv fluffy ntawm daim pam thiab xyuas kom meej tias daim pam muaj kev nqus tau zoo thiab number case hloov.
Tsis tas li ntawd, kev luam ntawv siab yog hais txog kev sib cuam tshuam ntawm cov ntawv luam ntawv phaj lub tog raj kheej thiab daim pam lub tog raj kheej, thiab nruab nrab ntawm daim pam lub tog raj kheej thiab lub tog raj kheej impression. Nws yog ib qho tsim nyog rau kev hloov tus cwj mem.
