Cellulose acetate yog dab tsi?
Cellulose acetate yog hais txog cov thermoplastic cob tau los ntawm esterification nrog acetic acid ua cov kuab tshuaj thiab acetic anhydride ua tus neeg sawv cev acetylating nyob rau hauv qhov kev txiav txim ntawm catalyst.organic acid esters.
Tus kws tshawb fawb Paul Schützenberge thawj zaug tsim cov fiber ntau hauv xyoo 1865, thiab nws yog ib qho ntawm thawj cov hluavtaws fibers.Tom qab xyoo ntawm kev tshawb fawb, txog 1940, cellulose acetate tau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv kev tsim cov iav tsom iav.
Yog vim li casacetate iav tsom iavthiaj li cim?
Acetate thav duab tuaj yeem tsim ntau yam xim thiab qauv yam tsis tas yuav pleev xim rau tus ncej.
Cov txheej txheej ntawm acetate coj ntau qib ntawm pob tshab thiab qauv rau tus ncej.Tom qab ntawd qhov kev tsim qauv zoo nkauj no ua rau acetate thav duab yog qhov kev xaiv zoo tshaj plaws dua li cov iav tsom iav niaj hnub.
Acetate ncej vs yas ncej.Qhov txawv ntawm lawv yog dab tsi?
Acetate thav duab yog sib dua ntawm qhov hnyav thiab feem ntau suav tias zoo dua li cov yas thav ntawv.Cov nplooj ntawv Acetate paub txog lawv cov khoom hypoallergenic, ua rau lawv xaiv rau cov neeg uas muaj tawv nqaij rhiab heev.Tsis zoo li qee cov yas lossis hlau, lawv tuaj yeem ua rau muaj kev tsis haum tshuaj.
Koj tuaj yeem nrhiav tau cov yas thav ntawv zoo heev.Txawm li cas los xij, lawv feem ntau tsis nyiam tshaj acetate thav duab rau cov laj thawj hauv qab no:
(1) Cov txheej txheem tsim khoom ua rau cov yas thav duab ntau dua li acetate thav duab;
(2) Yog tias tsis muaj lub nplhaib hlau rau lub tuam tsev, nws nyuaj rau kho cov iav yas;
(3) Kev xaiv tsawg dua ntawm cov xim thiab cov qauv
Tab sis ib yam, koj yuav pom tias acetate thav duab feem ntau kim dua li cov yas thav ntawv.
Tab sis qhov muag thav duab yog ib yam khoom niaj hnub uas peb siv tau ntev.Hauv qhov kev nkag siab no, kev ua haujlwm ntev yog qhov tseem ceeb, thiab acetate thav duab kav ntev dua.
Thaum twg koj yuav tsum xaiv ib khub ntawm acetate thav duab?
(1) Lub teeb thiab xis nyob
Raws li ib qho ntawm cov khoom siv niaj hnub no, lub teeb acetate eyeglass ncej yuav tsis muab lub nra hnyav rau ntawm tus choj ntawm lub qhov ntswg.Los ntawm qhib koj lub qhov muag thaum sawv ntxov mus so koj lub taub hau ntawm lub hauv ncoo thaum hmo ntuj, koj yuav tsis hnov qhov tsis xis nyob txawm tias koj yuav tsum hnav tsom iav txhua hnub.
(2) Durability
Qhov no yog qhov tseem ceeb uas ua rau lub qhov muag acetate sawv tawm ntawm cov yas yas lossis lwm yam khoom siv.Acetate thav duab yog tsim los ntawm kev txiav, tsim thiab polishing ntau yam khoom, uas ua rau lawv muaj zog li hlau thiab zoo tagnrho rau cov iav tsom iav.
(3) nplua nuj tsim
Koj puas xav xaiv ib lub iav tsom iav yog tias nws tsis muaj qhov tsim lossis xim?Ib qho pom tseeb yog tias acetate thav duab yog tsim los ua zam-thawj.Cellulose acetate tuaj yeem ua pov thawj tias yog lub iav tsom iav uas txhais tau tias zam thiab style.
Qhov saum npoo ntawm cov yas thav duab feem ntau yog txau nrog cov xim thiab cov qauv.Tej zaum nws yuav muaj ib tug zoo tsim los yog xim.Tab sis txij li nws tsuas yog superficial, kev siv txhua hnub tuaj yeem ua rau nws cov xim thiab cov qauv ploj mus.Tom qab ib xyoos lossis ob peb lub hlis, lawv yuav tsis zoo li lawv tau siv.Tsis zoo li cov iav tsom iav, acetate ua rau cov qauv tsim kom yooj yim dua, cov ntawv acetate tuaj yeem tsim nrog cov xim zoo nkauj, txheej txheej sib txawv thiab ntau xim xaiv los ntawm, cov qauv tsim muaj peev xwm tswj tau nws tus cwj pwm zoo dua yam tsis muaj tshuaj tsuag lossis pleev xim.
nyob rau hauv xaus
Acetate yog xis, hnav thiab stylish rau txhua yam koj xav tau.Yog li ntawd, nws tuaj yeem hais tias nws yog cov khoom siv zoo tshaj plaws rau kev ua cov iav tsom iav.
Yog li, thaum koj txiav txim siab yuav cov iav tsom iav tshiab lwm zaus, thov xav txog kev siv cov thav ntawv ua los ntawm acetate.Yog tias koj tsis paub meej tias yuav pib qhov twg, qhov pib sau tortoiseshell tej zaum yuav yog qhov chaw zoo pib.
