I-PVC SG-8
I-PVC SG-8,
intambo ducts ekrwada, I-PVC SG-8 esetyenziselwa ukuveliswa kweepaneli zodonga,
I-thermoplastic high-molecular polymer eyenziwe yi-polymerization yokumiswa kwe-vinyl chloride monomer.Ifomula yemolekyuli :- (CH2 – CHCl) n – (N: iqondo lepolymerization, N= 590 ~ 1500).Yeyona nto isetyenziswa kakhulu kwimveliso yeplastiki.Inozinzo oluhle lweekhemikhali, ukuxhathisa ukubola kunye nokuxhathisa kwamanzi.
Inkcazo
I-GB/T 5761-2006 Standard

Usetyenziso
I-polyvinyl chloride resin inoluhlu olubanzi lwezicelo, ezifana neendawo zangaphakathi zemoto, izinto zokuhombisa intsapho, i-advertising light box, izicathulo zezicathulo, iipayipi ze-PVC kunye nokufakelwa, iiprofayili ze-PVC kunye ne-hose, i-PVC sheet kunye nepleyiti, ifilimu eqengqelekayo, amathoyizi ane-inflatable, iimveliso zangaphandle; I-PVC ngocingo kunye nentambo, i-PVC yesikhumba eyenziweyo, iplanga kunye nomgangatho weplastiki, ibhodi edibeneyo, njl.
Ukupakishwa
I-25kg yelayini yengxowa yezandla enePE
Inkcazo:
Inkangeleko yePVC SG-8 yimpuphu emhlophe ehomogeneous, ngaphandle kwencasa kunye nevumba.
Ukusetyenziswa kwePVC resin brand SG-8:
I-resin brand SG-8 isetyenziselwa ukuveliswa kwezinto ezibunjiweyo ezinodonga oluncinci, iipaneli zodonga, i-cable ducts, i-semi-rigid iimveliso zenjongo Jikelele (i-linoleum, i-leathers eyenziwe, iifilimu zeplastiki, ukupakishwa kwe-polymer ezintathu-dimensional).
Indlela yokuvelisa:
Ifunyenwe ngepolymerization ye-vinyl chloride.I-polymerization iqhutyelwa ekumisweni (kwindawo yamanzi).
Kukho iindlela ezininzi zokuvelisa i-vinyl chloride esuka kwi-acetylene, i-ethylene dichloride, i-ethylene kunye ne-ethane.Iimveliso zethu zisekelwe kuphela ekusebenziseni i-ethylene.
