Chii chinonzi cellulose acetate?
Cellulose acetate inoreva thermoplastic resin inowanikwa ne esterification ine acetic acid sechinhu chinonyungudutsa uye acetic anhydride se acetylating agent pasi pechiito che catalyst. organic acid esters.
Sainzi Paul Schützenberge akatanga kugadzira faibha iyi muna 1865, uye yaive imwe yemafibhi ekutanga ekugadzira. Mushure memakore ekutsvagisa, kusvika 1940, cellulose acetate yakava imwe yezvakanyanya kukosha zvigadzirwa mukugadzirwa kwegirazi remaziso.
Sei vachidaroacetate eyeglass framessaka akasiyana?
Acetate mafuremu anogona kugadzirwa mumhando dzakasiyana-siyana uye mapatani pasina kudikanwa kwekupenda furemu.
Kuiswa kweacetate kunounza akasiyana madhigirii ekujeka uye pateni kune furemu. Ipapo iyi yakanaka dhizaini inoita kuti acetate mafuremu ave sarudzo yakanyanya kunaka pane yakajairwa magirazi egirazi epurasitiki mafuremu.
Acetate furemu vs epurasitiki furemu. Ndeupi musiyano uripo pakati pavo?
Acetate mafuremu akareruka muhuremu uye anowanzoonekwa semhando yepamusoro pane epurasitiki mafuremu. Mashizha eAcetate anozivikanwa neawo hypoallergenic zvimiro, achivaita sarudzo yakakurumbira kune vanhu vane ganda rinonzwa. Kusiyana nemamwe epurasitiki kana simbi mafuremu, anogona kukonzera allergic reaction.
Iwe unogona kuwana yakakwirira kwazvo mhando epurasitiki mafuremu. Nekudaro, ivo havawanzo kufarirwa pamusoro peacetate mafuremu nekuda kwezvikonzero zvinotevera:
(1) Maitiro ekugadzira anoita kuti furemu yepurasitiki ive brittle kupfuura iyo acetate furemu;
(2) Kana pasina simbi yesimbi yetemberi, zvakaoma kugadzirisa magirazi epurasitiki;
(3) Zvisarudzo zvishoma zvemavara uye mapatani
Asi chinhu chimwe chete, iwe unozoona kuti acetate mafuremu anowanzo kudhura kupfuura akajairwa epurasitiki mafuremu.
Asi mafuremu emeso chinhu chemazuva ese chatinoshandisa kwenguva yakareba. Mupfungwa iyi, kusimba kwakakosha, uye iyo acetate furemu inogara kwenguva refu.
Ndeipi yaunoda kusarudza peya yeacetate mafuremu?
(1) Rakareruka uye rakasununguka
Sezvimwe zvezvinodikanwa zvezuva nezuva, chiedza cheacetate chegirazi chemaziso hachizoisa mutoro unorema pabhiriji remhino. Kubva pakuvhura maziso ako mangwanani kusvika pakuzororera musoro wako pamutsago usiku, hauzonzwe kusagadzikana zvakanyanya kunyangwe uchifanira kupfeka magirazi zuva rese.
(2) Kugara kwenguva refu
Ichi ndicho chinhu chakakosha chinoita kuti ziso reacetate ribude kunze kwepurasitiki yechinyakare kana zvimwe zvinhu. Acetate mafuremu anogadzirwa nekucheka, kuumba uye kukwenenzvera akawanda zvidimbu zvezvinhu, izvo zvinoita kuti zvive zvakasimba sesimbi uye zvakanakira magirazi emaziso.
(3) Yakapfuma dhizaini
Ungafunga here kusarudza furemu yegirazi yemaziso kana isina dhizaini kana ruvara? Chimwe chinhu chiri pachena ndechekuti acetate mafuremu akagadzirwa kuti ave fashoni-kutanga. Cellulose acetate inogona kuratidza kuve girazi reziso rinotsanangura fashoni uye chimiro.
Pamusoro pemafuremu epurasitiki echinyakare anowanzo kupfapfaidzwa nemavara uye mapatani. Inogona kunge iine dhizaini yakanaka kana ruvara. Asi sezvo iri yepamusoro chete, kushandiswa kwezuva nezuva kunogona kuita kuti ruvara rwayo rwepamusoro uye pateni dzipere. Pashure pegore kana kuti kunyange mwedzi mishomanene, vangasaratidzika kuva vakanaka sezvavaisimboita. Kusiyana nemapuranga egirazi remaziso epurasitiki, acetate inoita kuti dhizaini ive nyore kuchengetedza, acetate sheet inogona kugadzirwa ine mavara ane mavara mapatani, akasiyana layering uye akawanda mavara ekusarudza kubva, recessed dhizaini inogona kuchengetedza hunhu hwayo zvakanyanya pasina kupfapfaidza kana kupenda.
mukupedzisa
Acetate yakasununguka, yakareruka uye yakashongedzwa kune zvese zvaunoda. Naizvozvo, zvinogona kutaurwa kuti ndiyo yakanakisa zvinhu zvekugadzira magirazi mafuremu.
Saka, paunofunga kutenga mafuremu matsva egirazi remaziso nguva inotevera, ndapota funga kushandisa mafuremu akagadzirwa kubva kuacetate. Kana iwe usina chokwadi chekutangira, iyo yekutanga tortoiseshell muunganidzwa inogona kunge iri nzvimbo yakanaka yekutanga.
