Umahluko phakathi kwe-LLDPE kunye ne-LDPE
Umahluko phakathi kwe-linear low density polyethylene (LLDPE) kunye ne-low density polyethylene (LDPE)
1. Ingcaciso
I-linear low density polyethylene (LLDPE) kunye ne-low density polyethylene (LDPE) zombini zizinto zeplastiki ezithathwe kwi-ethylene njengeyona nto iphambili ekrwada. Nangona kunjalo, ziyahluka ngokwesakhiwo; I-LLDPE ilungiselelwe kusetyenziswa itekhnoloji ye-catalyst enye, ekhokelela kulwakhiwo lomda kunye noxinaniso oluphezulu, ngelixa i-LDPE inolwakhiwo lwekhonkco olungaqhelekanga olunoxinaniso olusezantsi.
2. Iimpawu ezibonakalayo
I-LLDPE ibonisa iiyantlukwano ezahlukileyo ngokuxinana kunye nendawo yokunyibilika xa kuthelekiswa ne-LDPE. Uluhlu loxinaniso oluqhelekileyo lwe-LLDPE luphakathi kwe-0.916-0.940g/cm3, kunye noluhlu lwe-melting point ye-122-128℃. Ukongeza, i-LLDPE ibonisa amandla aphezulu kunye neempawu zokumelana nobushushu.
Kwelinye icala, i-LDPE iqhele ukuba noxinzelelo olusuka kwi-0.910 ukuya kwi-0.940g/cm3 kunye nendawo yokunyibilika ye-105-115 ℃ ngelixa ibonelela ngokuguquguquka okuphezulu kunye nokuqina.
3. Iindlela zokulungisa
Ngexesha lemveliso, i-LDPE inokusetyenzwa ngokubunjwa kokuvuthela okanye ubuchule bokukhupha ukwenza izikhongozeli ezahlukeneyo kunye nezinto zokupakisha ezinje ngeefilimu kunye neengxowa. Ngokwahlukileyo, ngenxa yomthwalo wayo ophezulu wokuthwala kunye namandla oomatshini, i-LLDPE ifaneleke ngakumbi kwiityhubhu ezikhuphayo kunye neefilimu.
4.Imimandla yesicelo
Ngenxa yeepropati zabo ezahlukeneyo kunye neendlela zokucubungula, i-LLDPE kunye ne-LDPE zifumana usetyenziso kwiindawo ezahlukeneyo. I-LLDPE ikufanelekele ukuvelisa iifilimu/iityhubhu ezikumgangatho ophezulu ezisetyenziswa ekwenzeni imathiriyeli yokupakisha efana nezagqubuthelo zezolimo, iifilimu ezingangeni manzi kunye neengcingo/iintambo. Ngokuchaseneyo, i-LDPE ifumana ukufaneleka okukhulu ekwenziweni kweemveliso ezithambileyo kubandakanya iiplagi zokudlala imibhobho yamanzi izikhongozeli kunye nezinto zokupakisha.
Ngokubanzi, Nangona zombini i-LLDP kunye ne-LPDE ziphantsi kodidi lweeplastiki ze-polyethylene, zibonisa umahluko obalulekileyo kungekuphela nje malunga neempawu ezibonakalayo, iindlela zokusetyenzwa kodwa kunye nemimandla yesicelo.
