Iinkcukacha zeMveliso

Iithegi zeMveliso

I-Low-density polyethylene (LDPE) yi-resin eyenziweyo esebenzisa inkqubo yoxinzelelo oluphezulu nge-polymerization yamahhala ye-ethylene kwaye ke ibizwa ngokuba "yi-polyethylene ephezulu yoxinzelelo".Ekubeni ikhonkco layo lemolekyuli linamasebe amaninzi amade namafutshane, i-LDPE ingaphantsi kwekristale kune-high-density polyethylene (HDPE) kwaye ubuninzi bayo buphantsi.Ibonisa ukukhanya, ukuguquguquka, ukuxhathisa okulungileyo komkhenkce kunye nokumelana nempembelelo.I-LDPE izinzile ngokwekhemikhali.Inokumelana kakuhle ne-acids (ngaphandle kwe-acid oxidizing kakhulu), i-alkali, ityuwa, iipropati ezigqwesileyo zombane.Isantya sokungena komphunga siphantsi.I-LDPE inolwelo oluphezulu kunye nokuqhubekeka kakuhle.Ilungele ukusetyenziswa kuzo zonke iintlobo zeenkqubo zokusetyenzwa kwe-thermoplastic, ezinje ngenaliti yokubumba, ukubumba i-extrusion, ukubunjwa kokuvuthela, i-rotomolding, i-coating, i-foaming, i-thermoforming, i-jet-jet welding kunye ne-thermal welding.

Isicelo

Ibakala bhanyabhanya le-LDPE lisetyenziswa ikakhulu kwimveliso yokupakisha ifilimu, ifilimu yezolimo kwaye inokudityaniswa ne-linear low-density polyethylene (LLDPE) ukuvelisa i-PE elungisiweyo.Ukongeza, inokusetyenziselwa ifilimu yokupakisha eshwabeneyo yobushushu, ifilimu elaminethiweyo, ifilimu ekhenkcezayo, ukupakishwa kwezonyango, ifilimu ene-multi-layer coextrusion, ifilimu yokupakisha enzima, iibhayibhile zokugquma, intambo yokuqhafaza, i-lining kunye ne-high-end i-chemical foaming.

I-LDPE (QLT04/QLF39) yifilim epakishwe ekuhle kakhulu ebonisa izinto ekrwada.

Ukupakishwa, uGcino kunye noThutho

I-resin ifakwe kwiingxowa ze-polypropylene ezifakwe ngaphakathi kwifilimu.Ubunzima obushiyekileyo bungama-25Kg/ibhegi.I-resin kufuneka igcinwe kwindawo yokugcina impahla, eyomileyo kwaye kude nomlilo kunye nelanga elithe ngqo.Akufunekanga ifunjwe kwindawo evulekileyo.Ngexesha lokuthuthwa, imveliso akufanele ibekwe kwilanga elinamandla okanye imvula kwaye akufanele ihanjiswe kunye nesanti, umhlaba, isinyithi esilahliweyo, amalahle okanye iglasi.Uthutho kunye nezinto eziyityhefu, ezidlekayo nezinokutsha akuvumelekanga ngokungqongqo.
