isicelo

I-resin yokuvelisa iiprofayili zeplastiki ze-PVC yi-polyvinyl chloride resin (PVC).I-Polyvinyl chloride yipolymer eyenziwe nge-vinyl chloride monomer.

I-resin ye-PVC inokuthi ihlelwe kwiindidi ezimbini, uhlobo olukhululekile (XS) kunye nohlobo oludibeneyo (XJ), kuxhomekeke kwi-agent agent kwi-polymerization.Ubungakanani bamasuntswana akhululekileyo yi-0.1-0.2mm, umphezulu awuqhelekanga, unepore, ufana nomqhaphu, kulula ukufunxa iplasticizer, ubungakanani bamasuntswana abambeneyo bungaphantsi kwe-0.1mm, umphezulu uqhelekile, uqinile, intenetya yetafile, kunzima ukufunxa iplasticizer, At ngoku, iintlobo ezikhululekileyo ezingaphezulu zisetyenziswa.

I-PVC inokohlulwa ibe yibakala eliqhelekileyo (i-PVC enetyhefu) kunye nebakala lococeko (i-PVC engeyiyo inetyhefu).Ibakala lokucoceka lifuna umxholo we-vinyl chloride (VC) ongaphantsi kwe-10 × 10-6, engasetyenziselwa ukutya kunye neyeza.Iinkqubo ezahlukeneyo zokwenziwa, iPVC inokwahlulwa ibe yiPVC yokunqunyanyiswa kunye ne-emulsion yePVC.Ngokomgangatho wesizwe we-GB/T5761-93 "Umgangatho wokuhlola we-polyvinyl chloride resin yenjongo ngokubanzi yendlela yokunqunyanyiswa", indlela yokunqunyanyiswa ye-PVC yahlulwe ibe yi-PVC-SG1 ukuya kwi-PVC-SG8 iintlobo ezisibhozo zee-resin, apho inani elincinci lincinci, Ubukhulu beqondo lepolymerization, ubunzima bemolekyuli bukwakhona Ubukhulu bokuqina, kokukhona ukunyibilika kuphezulu, kwaye kunzima ngakumbi ukusetyenzwa.

Xa ukhetha imveliso ethambileyo, i-PVC-SG1, i-PVC-SG2, kunye ne-PVC-SG3 isetyenziswa ngokubanzi, kwaye inani elikhulu leplastiki kufuneka lifakwe.Ngokomzekelo, ifilimu ye-polyvinyl chloride yenziwe nge-resin ye-SG-2, kwaye i-50 ukuya kwi-80 ye-plasticizer yongezwa.Xa kusetyenzwa iimveliso ezinzima, iiplasticizers ngokuqhelekileyo azifakwanga okanye zongezwa kwiimali ezincinci, ngoko ke iPVC-SG4, iPVC-SG5, iPVC-SG6, iPVC-SG7, kunye nePVC-SG8 isetyenziswa.

Umzekelo, i-SG-4 resin isetyenziselwa umbhobho oqinileyo we-PVC, i-SG-5 resin isetyenziselwa umnyango weplastiki kunye neprofayili yefestile, i-SG-6 resin isetyenziselwa ifilimu ecacileyo, kunye ne-SG-7 kunye ne-SG-8 resin isetyenziselwa iprofayile enogwebu oluqinileyo.Indlela ye-emulsion ye-PVC yokuncamathisela isetyenziselwa kakhulu ngesikhumba sokwenziwa, iphepha lodonga, isikhumba somgangatho kunye neemveliso zeplastiki.Abanye abavelisi be-PVC be-resin bathumela i-resin ye-PVC ngokweqondo le-polymerization (iqondo le-polymerization linani leyunithi yekhonkco, iqondo le-polymerization eliphindwe nge-molecular weight yekhonkco lilingana nobunzima be-molecular ye-polymer), njenge-PVC. i-resin eveliswe yi-Shandong Qilu Petrochemical Plant, iimveliso zefektri Yi-S-700;S-800;S-1000;S-1100;S-1200.

I-resin ye-SG-5 ine-degree of polymerization ukusuka kwi-1,000 ukuya kwi-1,100.I-PVC powder ngumgubo omhlophe onobunzima phakathi kwe-1.35 kunye ne-1.45 g / cm3 kunye nokuxinana okubonakalayo kwe-0.4 ukuya kwi-0.5 g / cm3.Sithatha umxholo weplastiki kwiimveliso zePVC njengeemveliso ezithambileyo nezilukhuni.Ngokubanzi, umxholo we-plasticizer yi-0 ~ 5 iinxalenye zeemveliso eziqinileyo, i-5 ~ 25 iinxalenye zeemveliso ezilukhuni, kunye namalungu angaphezu kwama-25 kwiimveliso ezithambileyo.

IZibo Junhai Chemical ngababoneleli abaphezulu bePvc Resin.Sinako ukubonelela PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.Kwaye ivela kubavelisi abaphezulu base China , njenge Erdos PVC Resin , Sinopec PVC Resin , Beiyuan PVC Resin , Xinfa PVC Resin , Zhong tai PVC Resin , Tianye PVC Resin .ext.

I-Polyvinyl chloride ineempawu ezibalaseleyo zezinto ezininzi eziluhlaza (ioli, i-limestone, i-coke, ityuwa kunye negesi yendalo), inkqubo yokuvelisa ekhulile, ixabiso eliphantsi, kunye noluhlu olubanzi lokusetyenziswa.Iye yaba yeyesibini ngobukhulu-injongo jikelele ye-resin emhlabeni emva kwe-polyethylene resin.I-29% yokusetyenziswa kwe-synthetic resin yehlabathi.I-Polyvinyl chloride kulula ukuyiqhuba kwaye iyakwazi ukuqhutyelwa ngokubunjwa, i-laminating, isitofu sokubumba, i-extrusion, i-calendering, i-blood folding, njl. njengeemveliso zeplastiki eziqinileyo ezifana neepleyiti, iingcango kunye neefestile, imibhobho kunye neevalvu.
