Filimo kala duwan ayaa badanaa loo isticmaalaa nolol maalmeedka. Qalab noocee ah ayaa filimadan laga sameeyay? Waa maxay astaamaha waxqabadka mid kasta? Waxyaabaha soo socdaa waa hordhac faahfaahsan oo ku saabsan filimada caagga ah ee sida caadiga ah loo isticmaalo nolol maalmeedka:
Filimka caagga ah waa filim ka samaysan polyvinyl chloride, polytrenene, polypropylene, polystyrene, polystyrene iyo resystyrene iyo resss kale, oo badanaa lagu isticmaalo baakadaha, dhismaha, iyo lakabka dahaarka ah, iwm.
Filimka caagga ah ayaa loo qaybin karaa
-Qilive Filim: filim aflagaado ah, filim loo yeedhay, filim fidsan, filim ka buuxo, iwm .;
- Filimka beeraha, filimka Mulch, iwm .;
-Films ee baakadaha (oo ay ku jiraan filimada isku-darka ee baakadaha dawooyinka, filimada isku-darka ee baakadaha cuntada, iwm).
Faa'iidooyinka iyo faa'iido darrooyinka filimka caagga ah:
Astaamaha waxqabadka ee filimada caagga ah ee caagga ah:
BIAXITITLITED Filimka Polypropylene (BOP)
Polypropylene waa remontlastic Resin pointlastity by polymerization ee pomplomelement. Qalabka PP waxay leeyihiin heerkulka deg-degga kuleylka kuleylka ah (100 ° C), daahfurnaan hooseeya, gloss hooseeya, iyo adkaanta hoose, laakiin xoog saamaynta, laakiin xoogga saameynta saameynta ee PP-gu ah ayaa ku kordhinaya kororka waxyaabaha ku jira ee PP-ga. Heerkulka jilicsanaanta vicat ee PP waa 150 ° C. Sababta oo ah heerka sare ee crystallallinity, walxahani waxay leeyihiin dusha sare ee dusha sare ee dusha sare iyo xoqidda xoqidda. PP ma laha dhibaatooyin is afgarad jawiga deegaanka ah.
BIEXITITLE ORDEPYPROPOPOPLENE Filim (BUP) waa sheyga baakadaha dabacsan ee daahfurka ah ee la soo saaray 1960-yadii. Waxay u isticmaashaa xariiq wax soo saar gaar ah si loogu daro polypropylene-ka ceeriin iyo waxyaabaha lagu daro, dhalaali lahaa oo cajiin gogosha, ka dibna waxay ku kala fidiyaan filim. Waxaa si weyn loogu isticmaalaa baakadaha cuntada, nacnaca, sigaarka, shaah, cabitaan casiir, caano, etc, oo leh sumcadda "boqoradaha baakadaha". Intaas waxaa sii dheer, waxaa sidoo kale lagu dabaqi karaa diyaarinta badeecadaha waxqabadka qiimaha badan ee lagu daray sida xuubka korantada iyo xuubka mikraka, sidaa darteed rajada horumarineed ee ka soo baxa filimyada kale ee loo yaqaan 'Plives' waa mid aad u ballaaran.
Filimka BUP ma leh oo keliya faa'iidooyinka cufnaanta hoose, iska caabinta suuxdinta wanaagsan iyo iska caabbinta kuleylka wanaagsan ee PP Resin, laakiin sidoo kale waxay leedahay guryo indhaha ah oo wanaagsan, awood farsamo oo wanaagsan iyo ilo hodan ah oo ah agab cayriin ah. Filimka BUP waxaa lagu dari karaa agabyo kale oo leh guryo gaar ah si loo sii wado hagaajinta ama hagaajinta waxqabadka. Qalabka sida caadiga ah loo isticmaalo waxaa ka mid ah filimka peypropylen (CPYPINVEYYNEN), POLYVINYLISE CHLOOSIGE (PVDC), filimka aluminium, iwm.
Filim polyetylen dhalo yar (ldpe)
Filimka polyetylene, oo ah PE pe, ayaa leh astaamaha caabbinta caabbinta iyo dhaxalka qoyaanka oo hooseeya.
Polyetylen-ka-yar ee cufan LPDE waa molecule molecule oo leh laamo dherer kala duwan oo silsiladaha ugu weyn, oo leh ilaa 15 illaa 30 oo ah laamaha, laakiin laamaha ka badan ee 1000 atom-ka ka mid ah oo ah silsiladaha ugu weyn. Sababtoo ah silsiladaha molikalalar waxay ka kooban yihiin silsilado muddo dheer oo gaagaaban, shey, jilicsanaan, xasillooni yar oo kiimiko ah, oo aan ahayn aaladda aashitada ee adag (marka laga reebo astaamaha cusbada. Turjunton iyo dhalaalaya, waxay leedahay xasillooni kiimiko heer leh, kuleyl kuleylka, iska-caabbinta biyuhu iyo iska caabbinta qoyaanka, iska caabin qoyan, iska caabin ah, waana la karkarin karaa. Faa'iido darrooyinka ugu weyn ayaa caqabad ku ah caqabad ku tahay oksijiinka.
Waxaa badanaa loo isticmaalaa sidii filim lakab ah oo gudaha ah oo ka kooban agabyada baakadaha dabacsan, oo sidoo kale waa xariiqda baakadaha balaastigga ah ee balaastigga ah ee joogtada ah, oo lagu xisaabtamo in kabadan 40% isticmaalka filimada baaqiga ee balaastikada ah. Waxaa jira noocyo badan oo filim oo ka mid ah filim xirmo baakad polyetylen ah, oo bandhigyadooda sidoo kale ay ka duwan yihiin. Waxqabadka filimka hal-lakabka ah waa mid keli ah, iyo waxqabadka filimka isku-dhafka ah waa mid dhameystiran. Waa maaddada ugu weyn ee baakadaha cuntada. Marka labaad, filimka polyetylen waxaa sidoo kale loo isticmaalaa garoonka injineerinka madaniga ah, sida Geomembrane. Waxay u dhaqmeysaa sidii biyo-joojin xagga injineerinka madaniga ah oo uu leeyahay isbadal aad u hooseeya. Filimka beeraha waxaa loo isticmaalaa beeraha, kaas oo loo qaybin karo filim shid, filim Mulch, filim daboolida qadhaadhka ah, filim kayd cagaaran iyo wixii la mid ah.
Filimka Polyester (PET)
Filimka Polyester (PET), oo loo yaqaan 'polyetylen', waa caag injineerineer heerkullo ah. Waa shey filim ah oo laga sameeyay go'yaal qaro weyn oo ka-saarista ka dibna ay si joogto ah u fiday. Filimka Polyester waxaa lagu gartaa astaamo farsamo yaqaan heer sare ah, adag, adkeyn iyo adkeyn, iska caabbinta, iska caabin heerkul ah, iska caabbinta kiimikada, caabbinta saliidda, caabbinta hawada iyo haynta hawada. Mid ka mid ah filimka tilmaanta rasmiga ah ee joogtada ah, laakiin cadaadiska Corona ma fiicna.
Qiimaha filimka polyester waa mid aad u sarreeya, dhumucdeedana guud ahaan waa 0.12 mm. Waxaa badanaa loo isticmaalaa sida ashyaa'da kore ee baakadaha cuntada ee baakadaha, oo ay leedahay daabacaad wanaagsan. Intaas waxaa sii dheer, filimka polyester waxaa badanaa loo isticmaalaa daabacaadda iyo baakadaha wax lagu buufiyo sida filimka ilaalinta deegaanka, filimka PET, iyo in la isticmaalo Fibers sida fiber-ka, qalabka dhismaha, qalabka dhismaha, iyo caafimaadka.
Filimka caagga ah ee Nylon (ony)
Magaca kiimikada ee Nylon waa Polyamide (PA). Waqtigan xaadirka ah, waxaa jira noocyo badan oo ah NYLON warshadaha oo warshadeed oo loo adeegsado soo saarista filimaanta waa filimyo aad u adag oo leh hufnaan aad u adag, iska caabin wanaagsan, iska caabin wanaagsan, iska caabbinta saliida, caabbinta saliida. Waa mid aad u fiican
Filimka polypropylene (CPP)
Si ka duwan habka loo yaqaan 'biaxpopylene' ee 'polypropylene' Waxaa lagu gartaa xawaaraha wax soo saarka ee degdegga ah, wax soo saarka sare, daahfurnaan filim wanaagsan, gloss, isku-dhafka dhumucnaanta, iyo isku dheelitirka wanaagsan ee guryaha kaladuwan. Sababtoo ah waa filim go'an oo la soo dhaafay, shaqada dabagalka sida daabacaadda iyo isku-darka aad bey u habboon tahay. CPP waxaa si ballaaran loogu isticmaalaa baakadaha dharka, ubaxa, cuntada, iyo baahiyaha maalinlaha ah.
Filimka caagga ah ee aluminiumka
Filimka aluminized-ka wuxuu leeyahay astaamaha filim caag ah iyo astaamaha birta. Doorka aluminium ee ku yaal dusha sare ee filimka waa in nalka gaashaanka loo yaqaan 'ultraviolet' oo ay ka hortagto shucaaca ultraviolet, oo aanu ka sii dheerayn nolosha shelf ee waxa ku jira, laakiin sidoo kale waxay wanaajisaa iftiinka filimka. Sidaa darteed, filimka aluminized-ka ayaa si weyn loogu isticmaalaa baakadaha isku-dhafka ah, oo inta badan loo isticmaalo baakadaha cuntada ee qalalan oo la isku duubay sida buskudka, iyo sidoo kale baakadaha kore ee daawooyinka iyo waxyaabaha la isku qurxiyo.
