Filimka OPP waa nooc ka mid ah filimka polypropylene, kaas oo loo yaqaan filimka polypropylene-ka-soo-baxsan (OPP) sababtoo ah habka wax-soo-saarka waa extrusion lakabyo badan. Haddi ay jirto hab-socod laba jiho ah oo ka shaqaynta, waxa loo yaqaan filim polypropylene ku jihaysan laba-jiho (BOPP). Midka kale waxaa loo yaqaan 'filim polypropylene cast' (CPP) oo ka soo horjeeda habka wadajirka ah. Saddexda filim waxay ku kala duwan yihiin hantidooda iyo isticmaalkooda.
I. Isticmaalka ugu muhiimsan ee filimka OPP
OPP: polypropylene ku jihaysan (filim), polypropylene ku jihaysan, waa hal nooc oo polypropylene ah.
Alaabooyinka ugu muhiimsan ee laga sameeyay OPP:
1, cajalad OPP: filimka polypropylene sida substrate, oo leh xoog cufan, khafiif ah, aan sun ahayn, dhadhan la'aan, deegaan saaxiibtinimo, isticmaalka ballaaran iyo faa'iidooyinka kale
2, Calaamadaha OPP:Waayo, suuqa waa xad buuxa oo wax soo saarka maalinlaha ah, muuqaalku waa wax walba, aragtida ugu horreysa ayaa go'aamisa dabeecadda iibsashada macaamilka. Shaambo, jel qubeyska, saabuunta iyo alaabada kale waxaa loo isticmaalaa in musqulaha diiran iyo qoyan iyo madbacadaha, shuruudaha calaamadda si ay u adkeyso qoyaanka oo aan ka dhicin, iyo caabbinta extrusion waa in la mid ah dhalada, halka dhalooyinka hufan Hufnaanta koollada iyo alaabta calaamadaynta waxay soo bandhigtay shuruudo adag.
Calaamadaha OPP marka loo eego calaamadaha waraaqaha, oo leh daahfurnaan, xoog sare, qoyaan, aan sahlanayn in la dhaco iyo faa'iidooyin kale, inkastoo qiimaha la kordhiyo, laakiin wuxuu heli karaa calaamad aad u fiican oo saameyn leh. Laakin waxay heli kartaa bandhig sumadeedka aad u wanaagsan iyo isticmaalka saamaynta. Horumarinta tignoolajiyada daabacaadda gudaha, tignoolajiyada dahaadhka, wax soo saarka calaamadaha filimada ee is-ku dhejinta iyo daabacaadda filimada hadda maaha dhibaato, waxaa la saadaalin karaa in isticmaalka gudaha ee calaamadaha OPP ay sii wadi doonaan kordhinta.
Maaddaama calaamadda lafteedu ay tahay PP, si fiican ayaa loogu dari karaa dusha weelka PP / PE, dhaqanka ayaa caddeeyay in filimka OPP uu hadda yahay qalabka ugu fiican ee calaamadaynta caaryada, cuntada iyo warshadaha kiimikada maalinlaha ah ee Yurub waxay ahayd tiro badan oo codsiyo ah, oo si tartiib tartiib ah ugu faafay gudaha, waxaa jira isticmaaleyaal aad u badan oo bilaabay inay fiiro gaar ah u yeeshaan ama isticmaalaan habka calaamadaynta caaryada.
Marka labaad, ujeedada ugu weyn ee filimka BOPP
BOPP: Filimka polypropylene ku jihaysan biaxil, sidoo kale hal nooc oo polypropylene ah.
Aflaanta BOPP ee inta badan la isticmaalo waxaa ka mid ah:
● filimka polypropylene ee guud laba-oriented,
● filim polypropylene laba-oriented kulaylka ku xidhan,
● Filimka baakadaha sigaarka,
● Filimka luul ka samaysan ee polypropylene oo laba-oriented ah,
● filim bir ah oo ka samaysan polypropylene laba-oriented,
● filim matte ah iyo wixii la mid ah.
Isticmaalka ugu muhiimsan ee filimada kala duwan waa sida soo socota:
1, Filimka caadiga ah ee BOPP
Inta badan waxaa loo isticmaalaa daabacaadda, samaynta bacaha, sida sharooto dhejis ah iyo isku dar ah substrates kale.
2. BOPP filimka kuleyliyaha
Inta badan loo isticmaalo daabacaadda, samaynta bacaha iyo wixii la mid ah.
3, Filimka baakadaha sigaarka BOPP
Isticmaal: Waxaa loo isticmaalaa baakadaha sigaarka xawaaraha sare leh.
4. BOPP filim luul ah
Loo isticmaalo baakadaha cuntada iyo alaabta guriga daabacaadda ka dib.
5, Filimka Metallized BOPP
Loo isticmaalo sida vacuum metallization, shucaac, substrate-ka-hortagga been abuurka, baakadaha cuntada.
6, Filimka matte ee BOPP
Loo isticmaalo saabuunta, cuntada, sigaarka, waxyaalaha la isku qurxiyo, alaabta dawooyinka iyo sanduuqyada kale ee baakadaha.
7. BOPP filim ka-hortagga ceeryaamo
Loo isticmaalo baakadaha khudaarta, miraha, sushi, ubaxa iyo wixii la mid ah.
Filimka BOPP waa qalab baakad dabacsan oo aad muhiim u ah, oo si ballaaran loo isticmaalo.
Filimka BOPP oo aan midab lahayn, aan ur lahayn, aan dhadhamin, aan sun ahayn, oo leh awood xoog badan, xoog saameyn leh, qallafsanaan, adkaan iyo daahfurnaan wanaagsan.
Tamarta dusha filimka BOPP waa yar tahay, xabag ama daabacaad ka hor daawaynta corona. Si kastaba ha noqotee, filimka BOPP ka dib daaweynta korona, wuxuu leeyahay laqabsi daabacan oo wanaagsan, wuxuu noqon karaa daabacaad midab leh wuxuuna heli karaa muuqaal qurux badan, sidaas darteedna caadi ahaan loo isticmaalo sida walxaha dusha sare ee filimka.
Filimka BOPP wuxuu sidoo kale leeyahay cillado, sida si sahlan loo ururiyo korantada taagan, ma jiraan wax kuleyl ah oo xira iyo wixii la mid ah. Xariiqda wax soo saarka ee xawaaraha sare leh, filimka BOPP wuxuu u nugul yahay koronto joogto ah, waxay u baahan tahay in lagu rakibo qalabka korontada ku shaqeeya.
Si loo helo filimka BOPP kulaylka lagu dabooli karo, BOPP filimka dusha sare ee corona daawaynta waxaa lagu dahaadhi karaa xabagta kulaylka lagu dabooli karo, sida cinjirka PVDC, latex EVA, iwm. Habka laminating extrusion waxaa loo isticmaali karaa si loo soo saaro filimka BOPP kulaylka-xidhi kara. Filimka waxaa si weyn loogu isticmaalaa rootiga, dharka, kabaha iyo baakadaha sharabaadada, iyo sidoo kale sigaarka, buugaagta daboolaya baakadaha.
Bilawga filimka BOPP ee xoogga jeexjeexa ka dib fidinta ayaa kordhay, laakiin xoogga jeexjeexa labaad waa mid aad u hooseeya, sidaas darteed filimka BOPP lagama tagi karo labada dhinac ee wejiga dhammaadka, haddii kale filimka BOPP waa sahlan tahay in la jeexjeexo daabacaadda. , lamining.
BOPP dahaarka leh sharooto isku dhejisan ayaa la soo saari karaa si loo xiro cajaladda santuuqa, waa qiyaasta BOPP ee BOPP isku dhejinta ayaa soo saari karta cajalad dabool ah, waa isticmaalka BOPP ee suuqa weyn.
Filimada BOPP waxaa lagu soo saari karaa habka filimada tuubada ama habka filimaanta fidsan. Sifooyinka filimada BOPP ee lagu helay habab farsameed oo kala duwan ayaa kala duwan. Filimka BOPP oo ay soo saartay habka filimka fidsan sababtoo ah saamiga xajmiga weyn (ilaa 8-10), sidaas darteed xoogga ayaa ka sarreeya habka filimka tuubada, dhumucda dhumucda filimka ayaa sidoo kale ka fiican.
Si loo helo waxqabad guud oo wanaagsan, isticmaalka habka waxaa badanaa loo isticmaalaa wax soo saarka hababka isku dhafan ee lakabyada badan.BOPP waxaa lagu dari karaa noocyo kala duwan oo kala duwan si loo daboolo baahiyaha codsiyada gaarka ah. Sida BOPP waxaa lagu dari karaa LDPE (CPP), PE, PT, PO, PVA, iwm. filimada waxaa lagu dhejin karaa cuntada saliidda leh.
Saddexaad, ujeedada ugu weyn ee filimka CPP
CPP: hufnaan wanaagsan, dhalaal sare, qallafsanaan wanaagsan, xannibaad qoyaan wanaagsan, iska caabin kulayl aad u fiican, si sahlan loo daboolo kuleylka iyo wixii la mid ah.
Filimka CPP ka dib daabacaadda, samaynta bacaha, ku habboon: dharka, dharka iyo bacaha ubaxa; dukumeenti iyo filim albums; baakadaha cuntada; iyo baakadaha xannibaadda iyo filimka birta ah ee qurxinta.
Isticmaalka suurtagalka ah waxaa sidoo kale ka mid ah: daboolka cuntada, daboolka macmacaanka (filim qalloocan), baakadaha dawooyinka (bacaha faleebada), bedelida PVC ee albamada sawirada, galalka iyo dukumentiyada, waraaqaha synthetic, cajalado isku dhejis ah, kaararka ganacsiga, xirayaasha giraanta iyo istaagida kiish isku dhafan.
CPP waxay leedahay iska caabin kulayl oo heer sare ah.
Maadaama barta jilicsan ee PP ay ku dhowdahay 140 ° C, filimka noocan ah waxaa loo isticmaali karaa meelaha sida kululaynta, bacaha uumiga iyo baakadaha aseptic.
Marka lagu daro aashito heer sare ah, alkali iyo iska caabin dufan ah, waxay ka dhigaysaa walxaha doorashada meelaha sida baakadaha alaabta rootiga ama alaabta la dahaadhay.
Badbaadada xidhiidhka cuntadeeda, wax qabadkeeda soo bandhigida aadka u fiican, saamayn kuma yeelan doonto dhadhanka cuntada gudaha, waxaanay dooran kartaa darajooyin kala duwan oo resin ah si loo helo sifooyinka la doonayo.
