Ndi zofunika kuteteza chilengedwe padziko lapansi, mapepala pulasitiki ma CD matumba pang'onopang'ono mu njira yoyenera, ndiye ubwino wa mapepala pulasitiki ma CD matumba?Chikwama cha pulasitiki cha pepala ndi mtundu wamphamvu kwambiri, anti kukalamba, kukana kutentha kwambiri, chinyezi, chopumira, chopanda poizoni komanso chosavulaza chikwama chatsopano.Amagwiritsidwa ntchito kwambiri muzakudya zopakidwa, chakudya chozizira chatsopano, wowuma, casein, chakudya, zomangira, mankhwala, mchere ndi mafakitale ena athumba lazinthu.
Ili ndi zabwino zisanu ndi chimodzi zotsatirazi
A, osasunga chinyezi
Chifukwa PVA ali kwambiri fluidity ndi filimu mapangidwe, m`kati kupanikizika pawiri kupanga wosanjikiza filimu mu wosanjikiza wamkati wa thumba pepala-pulasitiki ma CD, kuchita mbali ya gulu adhesion ndi chinyezi-umboni.Mbali inayi ili ndi mabowo ambiri osaoneka, omwe amatha kuteteza mamolekyu amadzi kunja kwa thumba la pulasitiki kuti asalowe m'thumba.
Awiri, kutentha kwambiri kukana
Mphamvu ya thumba la pepala-pulasitiki imayendetsedwa makamaka ndi warp ndi weft.Ulusi wa pYLON wosungunuka m'madzi umakhala ndi mphamvu yosweka nthawi zonse pa 180 ℃.Poyatsira pepala ndi madigiri a 183, kotero thumba lamagulu limakhalanso ndi mawonekedwe a kutentha kwambiri.
Chachitatu, anti-kukalamba
Chifukwa pepala si zophweka kukalamba zinthu zomera, ndi makhalidwe a opaque, thumba pulasitiki pepala mkati ndi kunja kwa pepala pansi cheza ultraviolet angathe kuteteza pepala si ukalamba, kuti thumba pamodzi ndi makhalidwe odana ndi ukalamba.
Chachinayi, kulimba kwambiri
Mphamvu ya thumba la pulasitiki yamapepala imayang'aniridwa makamaka ndi njira ya warp ndi weft.Chifukwa cha kusinthasintha kwapang'onopang'ono kwa thireyi ya weft, kunja kwa pepala lamkati kudzapanga mapangidwe ambiri a katatu a mesh, kuonjezera kwambiri kupsyinjika kwa mkati mwa thumba lachikwama, kotero kuti thumba lachikwama likhale ndi mphamvu zambiri.
Asanu, matumba akuunjika omwe saterera
Chifukwa m'kati kupanikizika pawiri, pamwamba pamwamba pa thumba pulasitiki pepala anapanga zambiri triangular mauna dongosolo, kuonjezera mikangano coefficient wa kunja kwa thumba, kuti thumba si kuzembera mu ndondomeko stacking (mmwamba). mpaka 40 digiri).Bokosi la Pulasitiki - "Internet + Pulasitiki" yophatikizana ndi chilengedwe chamakampani opanga mapulasitiki
Tetezani chilengedwe
Popeza ulusi wa pVA wosungunuka m'madzi sugwiritsidwa ntchito ndi resin acetal, ukhoza kusungunuka m'madzi otentha 80 kupanga guluu.Pambuyo pakuviika, zigawo zamkati ndi zakunja za pepala zimatha kubwezeretsedwanso kupanga mapepala obwezerezedwanso popanda kuwononga chilengedwe.
Chikwama cha pepala-pulasitiki, chomwe chimadziwikanso kuti atatu m'chikwama chimodzi cha pepala, ndi chidebe chaching'ono chochuluka, makamaka chopangidwa ndi anthu kapena forklift unit unit.Zosavuta kunyamula pang'ono ufa wochuluka ndi zida za granular.Ili ndi mawonekedwe amphamvu kwambiri, yopanda madzi, mawonekedwe apamwamba, kutsitsa kosavuta komanso kutsitsa, ndizodziwika komanso zothandiza zomwe zimagwiritsidwa ntchito popakira.
Matumba apulasitiki amagwiritsidwa ntchito makamaka kulongedza zida zomangira, matumba amatope, ufa wa putty, chakudya, zida zamafuta ndi zinthu zina zaufa kapena granular ndi zinthu zosinthika.M'zaka zaposachedwa, akhala akugwiritsidwanso ntchito kwambiri pakuyika malonda pa intaneti, zomata zamakhoma amitundu itatu, mipando yamagalimoto, zovundikira mipando ndi magawo ena.
