isicelo

I-resin yokukhiqiza amaphrofayili epulasitiki e-PVC yi-polyvinyl chloride resin (PVC).I-Polyvinyl chloride iyi-polymer eyenziwe nge-vinyl chloride monomer.

I-PVC resin ingahlukaniswa ngezinhlobo ezimbili, uhlobo oluxekethile (XS) kanye nohlobo oluhlangene (XJ), kuye ngokuthi i-ejenti ehlakazayo ku-polymerization.Usayizi wezinhlayiyana ezixekethile ngu-0.1-0.2mm, indawo engaphezulu ayijwayelekile, i-porous, i-cotton-like, kulula ukumunca i-plasticizer, usayizi wezinhlayiya ezihlangene ungaphansi kuka-0.1mm, ingaphezulu livamile, liqinile, ithenisi yetafula, kunzima ukumunca i-plasticizer, At okwamanje, izinhlobo ezixekethile ezengeziwe ziyasetshenziswa.

I-PVC ingahlukaniswa ngebanga elijwayelekile (i-PVC enobuthi) kanye nebanga le-sanitary (i-PVC engeyona enobuthi).Ibanga lenhlanzeko lidinga okuqukethwe kwe-vinyl chloride (VC) okungaphansi kwe-10 × 10-6, engasetshenziswa ekudleni nasemithi.Izinqubo ezahlukene zokwenziwa, i-PVC ingahlukaniswa ibe i-PVC yokumiswa kanye ne-emulsion PVC.Ngokwendinganiso kazwelonke ye-GB/T5761-93 “Inspection standard for general-purpose polyvinyl chloride resin for suspension method”, indlela yokumiswa i-PVC ihlukaniswe yaba yi-PVC-SG1 kuya ku-PVC-SG8 izinhlobo eziyisishiyagalombili zamarensi, lapho inombolo encane, likhulu izinga le-polymerization, isisindo samangqamuzana futhi Amandla amakhulu, ukuphakama kokuncibilika kuphezulu, futhi kuba nzima nakakhulu ukucubungula.

Uma ukhetha umkhiqizo othambile, i-PVC-SG1, i-PVC-SG2, ne-PVC-SG3 ngokuvamile isetshenziswa, futhi inani elikhulu le-plasticizer lidinga ukwengezwa.Isibonelo, ifilimu ye-polyvinyl chloride yenziwe nge-resin ye-SG-2, futhi izingxenye ezingu-50 kuya kwezingu-80 ze-plasticizer zengezwa.Lapho ucubungula imikhiqizo eqinile, ama-plasticizers ngokuvamile awangezwe noma angezwe ngamanani amancane, ngakho-ke i-PVC-SG4, i-PVC-SG5, i-PVC-SG6, i-PVC-SG7, ne-PVC-SG8 isetshenziswa.

Isibonelo, i-SG-4 resin isetshenziselwa ipayipi eliqinile le-PVC, i-SG-5 resin isetshenziselwa iphrofayili yomnyango wepulasitiki nefasitela, i-SG-6 resin isetshenziselwa ifilimu ebonisa ngale, futhi i-SG-7 ne-SG-8 resin isetshenziselwa iphrofayili enegwebu eliqinile.Indlela ye-emulsion ye-PVC yokunamathisela isetshenziselwa kakhulu isikhumba sokwenziwa, iphepha lodonga, isikhumba saphansi kanye nemikhiqizo yepulasitiki.Abanye abakhiqizi be-PVC resin bathumela inhlaka ye-PVC ngokwezinga le-polymerization (izinga le-polymerization inani lezixhumanisi zamayunithi, izinga le-polymerization eliphindwe ngesisindo samangqamuzana weketango lilingana nesisindo se-molecular ye-polymer), njenge-PVC. i-resin ekhiqizwa i-Shandong Qilu Petrochemical Plant, imikhiqizo yefekthri I-S-700;I-S-800;S-1000;I-S-1100;I-S-1200.

I-SG-5 resin ine-degree of polymerization kusuka ku-1,000 kuya ku-1,100.I-PVC powder iyimpushana emhlophe enokuminyana phakathi kuka-1.35 no-1.45 g/cm3 kanye nokuminyana okubonakalayo okungu-0.4 kuya ku-0.5 g/cm3.Sibheka okuqukethwe kwama-plasticizers emikhiqizweni ye-PVC njengemikhiqizo ethambile futhi eqinile.Ngokuvamile, okuqukethwe kwe-plasticizer kuyizingxenye ezingu-0 ~ 5 zemikhiqizo eqinile, izingxenye ezingu-5 ~ 25 zemikhiqizo eqinile, kanye nezingxenye ezingaphezu kuka-25 zemikhiqizo ethambile.

IZibo Junhai Chemical ingabaphakeli abaphezulu bePvc Resin.Singahlinzeka nge-PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.Futhi ivela kubakhiqizi abaphezulu baseChina , Abanjenge Erdos PVC Resin , Sinopec PVC Resin , Beiyuan PVC Resin , Xinfa PVC Resin , Zhong tai PVC Resin , Tianye PVC Resin .ext.

I-Polyvinyl chloride inezici ezivelele zensada yezinto zokusetshenziswa (uwoyela, i-limestone, i-coke, usawoti kanye negesi yemvelo), inqubo yokukhiqiza evuthiwe, intengo ephansi, kanye nezinhlobonhlobo zokusetshenziswa.Sekuyinhlaka yesibili ngobukhulu emhlabeni ngemuva kwe-polyethylene resin.Ama-29% okusetshenziswa kwe-resin yokwenziwa emhlabeni wonke.I-Polyvinyl chloride kulula ukuyicubungula futhi ingacutshungulwa ngokubumba, i-laminating, ukubunjwa komjovo, i-extrusion, i-calendering, i-blow molding, njll. I-Polyvinyl chloride isetshenziselwa ikakhulukazi ukukhiqiza imikhiqizo yepulasitiki ethambile efana nesikhumba sokwenziwa, amafilimu, nezigqoko zocingo, futhi. njengemikhiqizo yepulasitiki eqinile njengamapuleti, iminyango namafasitela, amapayipi namavalvu.
