I-E904 Shellac

I-Shellac (i-Shellac, i-E904) - i-glazier. I-resin yemvelo ekhiqizwa yi-lacworm yezinambuzane (i-Laccifer lacca), isinambuzane kwezinye izihlahla ezishisayo nezishisayo eNdiya naseNingizimu-mpumalanga ye-Asia (iCroton laccifera nezinye).

IShellac isetshenziswa ekwenziweni kwama-lacquers, izinto zokwambathisa kanye nokuthwebula izithombe. Ngaphambi kokusungulwa kwe-vinyl ngo-1938, i-shellac yayisetshenziselwa ukukhiqizwa kwamarekhodi.

I-Shellac - leli gama kubantu abaningi lihlotshaniswa nenqubo ye-manicure. Eqinisweni, into, nakuba ihlobene nezimonyo zokuhlobisa izipikili, iyaziwa ngaphansi kwekhodi E904 ezigabeni zamazwe ngamazwe zezithako zokudla, futhi ibhekisela ezingxenyeni ezilwa nomlilo kanye ne-glazing ezisetshenziswa embonini yokudla. Uqweqwe olucwebezelayo kumaswidi, ama-dragees, ama-lollipops, ushokoledi ngisho nezithelo, ngokuvamile kuvame ukuvela ngenxa ye-shellac yokudla. Amanye amagama ezithako yi-sticklak, gummilak resin noma i-stocklak, futhi enye yezinzuzo ezaziswa ngayo abakhiqizi bokudla umsuka wako wemvelo.

Incazelo ye-SHELLAC E904

I-Shellac E904 iyi-amphora granular resin, eyingxenye yezithako zokudla: i-anti-flaming and glazing agent. I-resin inomsuka wemvelo ngokuphelele futhi ivunyelwe. Isetshenziswa kokubili embonini yokudla nakwezokwelapha, i-cosmetology kanye nokwakhiwa. Amajazi aphezulu ane-E904 amelana kakhulu nokungcola, uthuli, imihuzuko nokukhanya. Umbala wemvelo we-shellac unikeza ifenisha ukubukeka kwe-monarchic antique.

Indlela yokuthola i-Shellac E904

I-Shellac ingumkhiqizo olahlwa yizikelemu. Indawo yezinambuzane yiThailand neNdiya. Izikelemu zihlala ezihlahleni futhi zidla amajusi azo. Izinto ezigaywe kabusha zikhishwa ngezimbotshana zesikhumba. Lena impahla eluhlaza yokuthola isithasiselo se-E904. Izinto ezingavuthiwe ziyacutshungulwa, okuncike emkhiqizweni wokugcina wezimboni. I-resin ingathengiswa ngefomu elomile. Kungaba ama-flakes noma amatshe. Okunye okujwayelekile yi-shellac ewuketshezi. Ukuze uyithole, i-resin ichithwa ku-ethyl alcohol.

Izakhiwo ze-E904, izici zamakhemikhali kanye nendlela yokukhiqiza

Isengezo sokudla se-Shellac ngokwesakhiwo simele izinhlanganisela nama-esters ama-aromatics nama-fatty hydroxy acids - i-aluretic, i-shellolic nezinye. Ukwakheka kuqukethe ama-lactones, ama-pigments kanye ne-shellac wax. Isithako esiyinhloko esisebenzayo (i-resin) singama-60-80% wesengezo se-E904.

I-substance ngokuvamile ingena ekukhiqizeni ngendlela yama-flakes angamamilimitha ambalwa kuphela ubukhulu. I-Shellac ayincibiliki nhlobo emanzini, amafutha, i-acetone nama-ethers. Inoncibilika kahle kuma-alkali, otshwaleni be-aliphatic, ukuncibilika okuphakathi kwe-benzene, i-ethanol.

Iphuzu lokuncibilika kwento lingama-80 degrees Celsius. Ngaphandle kokumelana namanzi, iphinde ibe nokumelana nokuchayeka kokukhanya, kanye nomphumela wokufaka ugesi kagesi.

Ukukhulunywa kokuqala kokusetshenziswa kwale resin kuhlehlela emuva ku-1st millennium BC. I-India kanye namazwe aseNingizimu-mpumalanga ye-Asia - indawo yokuhlala yezinambuzane ezibizwa ngokuthi i-Laccifer lacca (izimbungulu ze-lacquer), ezifana nezimbungulu.

Lezi zinambuzane zidla inhlaka yezihlahla kanye nejusi ekhishwa emagatsheni, emagxolweni nasemaqabunga ezihlahla. Ngenxa yezinqubo zokugaya ukudla kwezibungu, izinto ezizidlayo ziphenduka inhlaka, izinambuzane eziyibeka ngenxa yalokho emagatsheni nasemagxolweni ezihlahla. I-resin noma i-lacquer yoma ukuze yakhe uqweqwe oluqoqwe ukuze kuqhutshekwe nokucubungula.

Okokuqala, izinto eziluhlaza zichithwa nge-sodium carbonate - ngale ndlela i-shellac yesikhathi esizayo ihlanzwa ngokungcola okuhlukahlukene kwezinto eziphilayo (izinhlayiya zezinambuzane, amaqabunga).

Into ewumphumela ixutshwa kusetshenziswa i-sodium hypochlorous acid bese yomiswa.

Ukuze ukhiphe i-wax ku-additive, ekugcineni ibhekene nokusabela ngesisombululo esibuthakathaka se-sulfuric acid futhi i-wax engancibiliki iyahlungwa. Ngenxa yalokho, i-shellac e-bleached ehlanjululwe ku-wax itholakala.

Ngaphandle kwemibala emhlophe, ingaba yiwolintshi noma ibe nsundu ngokukhanyayo. Kungenzeka futhi ukuhlanganisa isithasiselo esingenambala.

Inhloso yezobuchwepheshe ye-additive ye-E904 ukwakhiwa kwezingubo ezicwebezelayo, ukuvimbela noma ukunciphisa ukuqina kokwakheka kwegwebu, kanye nokuvimbela ukunamathela kwezinhlayiya ezicwebezelayo komunye nomunye.

Indlela i-substance esetshenziswa ngayo embonini

Embonini yamakhemikhali, i-E904 isetshenziselwa ukwenza amapende, amapholishi, amavanisha wezinsimbi zomculo zokhuni nefenisha. Ngaphambi kokusungulwa kwe-vinyl eminyakeni engu-40 yekhulu leminyaka elidlule, ingxenye yayisetshenziswa ekwenzeni amarekhodi.

I-Shellac iyisisekelo sefilimu ye-polyethylene kanye ne-aluminium foil, isetshenziswa embonini yendwangu ukuqinisa izindwangu ezizwakalayo nezifanayo, futhi iyingxenye yamavarnish kagesi afaka i-varnish yokufaka amakhoyili ezinto zikagesi kanye nokucubungula izingxenye zikagesi.

I-Shellac iyingxenye yezifutho zezinwele nama-shampoos, imikhiqizo ehlukahlukene yesitayela ehlala isikhathi eside, kanye ne-mascara engenamanzi.

Imboni yezimonyo ayiphelele ngaphandle kwe-shellac: abakhiqizi bazisa kakhulu izindawo zayo ezivimbela amanzi, ukuzinza kwezinga lokushisa kanye nekhono lokudala ukuthungwa okudingekayo komkhiqizo.

Kusukela ngo-2010, e-United States kwaqala ukukhiqizwa ngobuningi be-gel polish resistant, equkethe i-additive E904, ngokulandelana, yayibizwa ngokuthi "i-Shellac". I-coating ihlukaniswa ngamandla ayo akhethekile, ukugcwala kombala kanye nekhono lokulinganisa ipuleti le-nail.

Ibuye yengezwe ezithakweni zokudla kanye namagobolondo okuvikela amawakisi kwezinye izinhlobo zikashizi.

Ngendlela ye-glazing noma i-defoaming component, i-E904 itholakala ekudleni okunjalo:

• izithelo ezintsha (izithelo ze-citrus, amapentshisi, amapheya, ama-apula, amakhabe - ukwelashwa kwendawo);
• amaswidi, ama-lollipops, ama-dragees, ushokoledi;
• imikhiqizo kafulawa ene-icing;
• ikhofi lokusanhlamvu;
• ushingamu;
• i-marzipan mass.

Ngaphandle kokukhiqizwa kokudla, i-shellac iphinde yathola ukusetshenziswa kwayo embonini yemithi - njenge-glazing yezinye izidakamizwa ngendlela yamaphilisi nama-dragees.

Ingabe i-shellac ingaba nomthelela empilweni yomuntu

Ayikho impendulo ecacile evuna noma ngokumelene nokusetshenziswa kwe-shellac ekudleni namuhla.

Into yacwaningwa ngaphansi kwezimo zaselabhorethri, futhi akukho datha esemthethweni mayelana nobuthi obungaba khona noma i-oncogenicity eyamenyezelwa. Ingozi kuphela engaba nayo ukungezwani komzimba.

Kwezinye izimo zokungabekezelelani komuntu ngamunye, ukudla nezimonyo ezinento ekubunjweni kungabangela ukulunywa nokuqubuka kwesikhumba.

Isengezo sokudla i-E904 asimuncwa umzimba nganoma iyiphi indlela futhi sikhishwa kuso singashintshiwe.

Imithetho yokupakisha neyokugcina

I-Shellac ingathuthwa futhi igcinwe ezitsheni ezihlukahlukene, isibonelo, i-jute noma izikhwama zendwangu zokwenziwa (izinto ezisetshenziswayo kufanele zigunyazwe ukuxhumana nemikhiqizo yokudla), emabhokisini okhuni noma amabhokisi amakhadibhodi, amabhokisi, izigubhu.

Ezitolo, i-substance itholakala ezitsheni ze-foil noma emaphaketheni epulasitiki.

Isengezo se-E904 sihlukaniswa ngumphakathi womhlaba njengesiphephe kakhulu. Ukusetshenziswa kwayo kuvunyelwe emazweni amaningi: e-USA, Canada, emazweni e-EU, eRussia. Ushokoledi wezemidlalo we-Ritter odumile ekubunjweni kwawo uqukethe i-shellac njengengxenye ecwebezelayo.

Njengoba into ingokwemvelo, inabaphikisi abambalwa: ngokuvamile, ukusetshenziswa kwayo njengengxenye yemikhiqizo yokudla akubangeli ingxabano.

Ucwaningo lwemiphumela ye-shellac empilweni yomuntu luyaqhubeka nanamuhla, kodwa kuze kube manje zonke izifundo zibonisa ukuthi ukudla okungeziwe kwe-E904 akuzuzi, kodwa akulimazi umzimba.
