Waa maxay Noocyada kala duwan ee Polyethylene?
Polyethylene waxaa badanaa loo kala saaraa mid ka mid ah dhowr isku dhis oo waaweyn, kuwa ugu caansan oo ay ku jiraan LDPE, LLDPE, HDPE, iyo Ultrahigh Molecular Weight Polypropylene. Kala duwanaanshiyaha kale waxaa ka mid ah cufnaanta dhexdhexaadka ah ee Polyethylene (MDPE), Polyethylene Ultra-hoose-molecular (ULMWPE ama PE-WAX), Polyethylene-miisaanka-molecular-sare (HMWPE), Polyethylene-ku-xiran cufnaanta-sare (HDXLPE), Iskutallaabta polyetylen (PEX ama XLPE), polyetylen cufnaanta aadka u hooseeya (VLDPE), iyo polyetylen koloriin leh (CPE). Cufnaanta-hooseeya ee Polyethylene (LDPE) waa shay aad u dabacsan oo leh sifooyin qulqulaya oo gaar ah oo ka dhigaya mid si gaar ah ugu habboon bacaha wax iibsiga iyo codsiyada kale ee filimada caagga ah. LDPE waxa ay leedahay ductility sare laakiin xoog adkaysi hoose, taas oo ka muuqata dunida dhabta ah iyada oo u janjeera in ay fidiyaan wh... -

Waa maxay Filimka Dul-duubka ee Polypropylene ee Biaxial Oriented?
Filimka polypropylene ee ku jihaysan Biaxial (BOPP) waa nooc ka mid ah filimada baakadaha dabacsan. Filimka dusha sare ee polypropylene u janjeedha biaxil waxa lagu fidiyay mashiin iyo jihooyin leexsan. Tani waxay keenaysaa jihada silsiladda molecular ee labada dhinac. Noocaan filimka baakadaha dabacsan waxaa lagu abuuray habka wax soo saarka tuubada. Xumbo filim u qaabaysan ayaa la buufiyay oo la kululeeyay ilaa barta jilicsanaanta (tani way ka duwan tahay barta dhalaalka) waxaana lagu fidiyaa mishiino. Filimku wuxuu fidiyaa inta u dhaxaysa 300% - 400%. Haddii kale, filimka waxaa sidoo kale lagu fidin karaa habka loo yaqaan soo saarista filimada teendhada. Farsamadan, polymers-yada waxaa lagu dulsaaraa duub la qaboojiyey (sidoo kale loo yaqaan xaashida saldhigga) waxaana lagu sawiraa jihada mashiinka. Filimka Tenter-frame ayaa noo soo saaraya... -

Sida looga fogaado in lagu khiyaamo marka la iibsanayo alaabta Shiinaha gaar ahaan alaabta PVC .
Waa inaan qiranno in ganacsiga caalamiga ahi ay ka buuxaan khataro, oo ay buuxiyeen caqabado badan marka iibsaduhu dooranayo alaab-qeybiyaha. Waxaan sidoo kale qiraynaa in kiisaska khiyaanada ay dhab ahaantii ka dhacaan meel kasta oo ay ku jirto Shiinaha. Waxaan ahaa iibiye caalami ah muddo ku dhow 13 sano, oo la kulmay cabashooyin badan oo ka yimid macaamiil kala duwan oo ay khiyaameeyeen hal mar ama dhowr jeer alaab-qeybiye Shiinees ah, siyaabaha khiyaamada waa wax "qosol badan", sida helitaanka lacag la'aan, ama bixinta tayada hoose alaab ama xitaa keenista badeeco aad u kala duwan. Alaab-qeybiye ahaan naftayda, waxaan si buuxda u fahamsanahay sida dareemku yahay haddii qof uu lumiyay lacag-bixin weyn gaar ahaan marka ganacsigiisa uu hadda bilaabmayo ama uu yahay ganacsade cagaaran, lumay waa inuu noqdaa mid aad u soo jiidasho leh isaga, waana inaan qiranno taas si aan u helno. . -
