Taariikhda
1928 Scotch cajalad, Richard Drew, St. Paul, Minnesota, USA
Codsashada May 30, 1928 gudaha Boqortooyada Ingiriiska iyo Mareykanka, Drew wuxuu sameeyay xabag aad u fudud oo hal taabasho ah. Isku daygii ugu horreeyay ma ahayn mid ku dheggan, sidaas darteed Drew ayaa loo sheegay: "Shaygan ku celi madaxdaada Iskotishka oo weydii inay dhejiyaan koollo badan!" ("Scotland" macnaheedu waa "bakhayl") Laakin intii lagu jiray Niyad-jabka Wayn, dadku waxay heleen boqollaal isticmaalka cajaladan, laga bilaabo dhar-goynta ilaa ilaalinta ukunta.
Maxay tahay sababta cajaladdu wax ugu dhejin karto? Dabcan, waa sababta oo ah lakabka dhejiska ee dusha sare! Xabagta ugu horreysa waxay ka timid xayawaanka iyo dhirta. Qarnigii sagaal iyo tobnaad, caaggu wuxuu ahaa qaybta ugu muhiimsan ee xabagta; halka waqtiyada casriga ah, polymers kala duwan ayaa si weyn loo isticmaalaa. Xabagtu waxay ku dhegi kartaa walxaha, sababtoo ah molecules laftooda iyo molecules-yada lagu xirayo si ay u sameeyaan curaarta, dammaanadda noocan oo kale ah waxay si adag ugu dhejin karaan unugyadu. Halabuurka xabagta, marka loo eego noocyada kala duwan iyo noocyada kala duwan, waxay leeyihiin noocyo kala duwan oo polymers ah.
Sharaxaada Alaabta
Cajaladda wax lagu xidho waxa kale oo loo yaqaan cajalad bopp ah, cajalad baakad ah, iwm. Waxay isticmaashaa BOPP filim polypropylene ku jihaysan BOPP sida walxaha saldhigga ah, waxayna si siman u dabaqaysaa emulsion koollada xasaasiga ah ka dib kuleylka si ay u sameyso 8μm--28μm. Lakabka dhejiska ah waa shay lagama maarmaanka u ah nolosha shirkadaha warshadaha fudud, shirkadaha, iyo shakhsiyaadka. Wadanku ma laha halbeeg qumman oo loogu talagalay warshadaha cajaladaha ee Shiinaha. Waxaa jira hal halbeeg oo warshadeed “QB/T 2422-1998 BOPP cadaadiska xasaasiga ah ee sharoobada dhejinta” Kadib daawaynta korona ee cadaadiska sare ee filimka BOPP ee asalka ah, dusha qallafsan ayaa la sameeyay. Ka dib markaad marso koollada dusheeda, duubka jumbo ayaa marka hore la sameeyay, ka dibna jarjar yar yar oo tilmaamo kala duwan leh mashiinka wax lagu gooyo, kaas oo ah cajaladda aan isticmaalno maalin kasta. Qaybta ugu muhiimsan ee emulsion xasaasiga ah ee cadaadiska waa butyl ester.
Tilmaamaha ugu muhiimsan
Cajalado tayo sare leh iyo kuwo tayo sare leh ayaa leh waxqabad wanaagsan xitaa cimilo aad u adag, oo ku habboon in lagu kaydiyo bakhaarrada, weelasha maraakiibta, ka hortagga xatooyada alaabta, furitaanka sharci darrada ah, iwm. Bixinta ilaa 6 midab iyo cabbirro kala duwan oo dhexdhexaad ah iyo shakhsi shakhsi ahaaneed. cajalad
Xoogga koollada degdega ah: cajaladda wax lagu xidhaa waa mid dhegdheg leh oo adag.
Awoodda hagaajinta: Xataa cadaadis aad u yar, waxaa lagu hagaajin karaa qaybta shaqada iyadoo loo eegayo fikradahaaga.
Fudud in la jeexjeexo: fududahay in la jeexjeexo duubista cajaladda iyada oo aan la kala bixin oo la jiidin cajaladda.
Dabaylaha la xakameeyey: Cajaladda wax lagu xidho waxaa laga soo jiidan karaa duubka si la kontaroolo, aan aad u dabacsanayn ama aad u dhagan.
Dabacsanaan: Cajaladda wax lagu xidho waxay si fudud ula qabsan kartaa qaabka qalooca ee degdega ah ee isbeddelaya.
Nooca khafiifka ah: Cajaladda wax lagu xidho kama tagi doono dhigaalka qaro weyn.
Jilicsanaan: Cajaladda wax lagu xidho way siman tahay marka la taabto mana ka xanaajiso gacantaada marka gacanta lagu cadaadiyo.
Kahortagga wareejinta: wax dhejis ah lagama tagi doono ka dib marka cajaladda wax lagu xidho la saaro.
Iska caabinta dareeraha: Walxaha dhabarka ee cajaladda wax lagu xidho waxay ka hortagtaa dhexgalka dareeraha.
Ka-hortagga-jajabinta: Cajaladda wax lagu daboolaa ma dillaaci doonto.
Dib-u-celinta ka-hortagga: Cajaladda wax lagu daboolo waxaa lagu kala bixin karaa dusha qaloocan iyada oo aan la arkin ifafaale dib u gurasho.
Ka-hortagga ka-qaadista: Rinjiga ayaa si adag loogu dhejin doonaa shayga dambe ee cajaladda wax lagu xidho.
