imikhiqizo

Ukwakhiwa kwepulasitiki ye-PVC,
I-PVC Resin, I-PVC resin kanye nesengezo, I-PVC resin yokukhiqiza ipayipi, I-PVC SG-5, I-PVC SG-8, I-PVS SG-7,

Ukwakhiwa kwepulasitiki ye-PVC ikakhulukazi yakhiweI-PVC resin kanye nesengezos, okuyizithasiselo ngokusho komsebenzi ezihlukaniswe zibe: i-heat stabilizer, i-lubricant, i-modifier yokucubungula, isishintshi somthelela, isigcwalisi, i-ejenti yokuguga, umbala nokunye.Ngaphambi kokuklama ukwakhiwa kwe-PVC, kufanele siqale siqonde izakhiwo ze-PVC resin kanye nezithasiselo ezihlukahlukene.

Izinto zokusetshenziswa kanye nezithasiselo

I-PVC resin

Ukukhiqizwa kwephrofayili yepulasitiki ye-PVC ye-resin yi-polyvinyl chloride resin (PVC), i-PVC yenziwe nge-vinyl chloride monomer polymerization polymer, iphuma isibili ku-PE, ibeka okwesibili.

I-PVC resin ingahlukaniswa ibe uhlobo oluxekethile (XS) kanye nohlobo oluqinile (ⅺ) ngenxa yezisabalalisi ezihlukene ku-polymerization.Usayizi wezinhlayiyana ezixekethile ngu-0.1-0.2mm, indawo engaphezulu ayijwayelekile, i-porous, i-cotton ball, kulula ukumunca i-plasticizer, usayizi wezinhlayiyana ezihlangene ungaphansi kuka-0.1mm, imithetho engaphezulu, eqinile, i-table tennis shape, akulula ukumunca i-plasticizer, ukusetshenziswa kwamanje yohlobo oluxekethile ngaphezulu.

I-PVC ingahlukaniswa ngebanga elijwayelekile (i-PVC enobuthi) kanye nebanga lezempilo '(i-PVC engeyona enobuthi).Izidingo zebanga lezempilo zokuqukethwe kwe-vinyl chloride (VC) eziphansi kune-LOXL0-6, zingasetshenziswa ekudleni nasemthini.Inqubo yokwenziwa ihlukile, i-PVC ingahlukaniswa i-PVC yokumiswa kanye ne-emulsion PVC.Ngokwendinganiso kazwelonke ejwayelekile ye-GB/T5761-93 “indlela yokumiswa ejwayelekile ye-polyvinyl chloride yokuhlola inhlaka”, indlela yokumiswa i-PVC ihlukaniswe yaba yi-PVC-SGL kuya ku-PVC-SG8JK resin, inombolo encane, izinga le-polymerization likhulu, likhulu kakhulu. isisindo samangqamuzana, amandla aphezulu, kodwa uma ukuncibilika kunzima kakhulu, ukucubungula nakho kunzima kakhulu.Ukukhetha okuqondile, ukwenza imikhiqizo ethambile, ukusetshenziswa okujwayelekile kwe-PVC-SGL, i-PVC-SG2, uhlobo lwe-PVC-SG3, udinga ukwengeza inani elikhulu lama-plasticizers.Isibonelo, ifilimu ye-PVC isebenzisa i-resin ye-SG-2, enezela izingxenye ezingu-50 kuya kwezingu-80 ze-plasticizer.Futhi lapho ucubungula imikhiqizo eqinile, ungangezi noma wengeze i-plasticizer ngenani elincane kakhulu ngokuvamile, sebenzisa i-PVC-SG4, i-VC-SG5, i-PVC-SG6, i-PVC-SG7, i-PVC-SG8 ngakho.Okufana nepayipi eliqinile le-PVC lisebenzisa i-SG-4 resin, amaphrofayili eminyango yepulasitiki namafasitela asebenzisa i-SG-5 resin, ishidi elikhanyayo eliqinile lisebenzisa i-SG-6 resin, amaphrofayili egwebu eliqinile asebenzisa i-SG-7, SG-8 resin.Futhi i-emulsion ye-PVC yokunamathisela isetshenziselwa kakhulu isikhumba sokwenziwa, iphepha lodonga nesikhumba saphansi kanye nemikhiqizo yepulasitiki yokucwilisa.Abanye abakhiqizi be-PVC resin be-PVC resin ngokusho kwe-polymerization degree (i-polymerization degree inombolo ye-unit chain, i-polymerization degree iphindwe ngesisindo se-molecular of the chain ilingana nesisindo samangqamuzana se-polymer) ngezigaba, njenge-Shandong Qilu petrochemical general plant. ukukhiqizwa kwe-PVC resin, imikhiqizo yefekthri ye-SK-700;SK - 800;SK - 1000;SK - 1100;I-SK – 1200, njll. Izinga elihambisanayo le-polymerization ye-SG-5 resin yi-1000 — 1100. Izakhiwo zomzimba nezamakhemikhali ze-PVC resin zibona okwesine.

I-PVC powder iyimpushana emhlophe enobuningi obungu-1.35 — 1.45 g/cm3 kanye nokuminyana okubonakalayo okungu-0.4-0.5 g/cm3.Hlola usayizi wokuqukethwe we-plasticizer ungaba imikhiqizo ethambile, eqinile, okuqukethwe kwe-plasticizer jikelele 0-5 yimikhiqizo eqinile, i-5-25 iyimikhiqizo eqinile, engaphezu kuka-25 yimikhiqizo ethambile.

I-PVC iwuhlobo lwe-amorphous, i-polar polar, izinga lokushisa elithambile kanye nezinga lokushisa elincibilikayo liphezulu, i-PVC ehlanzekile ngokuvamile kufanele ibe ku-160-210 ~ C ukucutshungulwa kwe-plasticizing, ngenxa yesibopho se-polar phakathi kwama-macromolecules ukuze i-PVC ibonise ukusebenza okunzima nokuphukayo.Ngaphezu kwalokho, ama-molecule e-PVC aqukethe amaqembu e-chlorine, lapho izinga lokushisa lifinyelela ku-120 ~ C, i-PVC ehlanzekile izoqala ukususa ukusabela kwe-HCl, kuzoholela ekulimazeni okushisayo kwe-PVC.Ngakho-ke, zonke izinhlobo zezithasiselo kufanele zengezwe ekucubunguleni ukuguqulwa kwe-PVC kanye nokuguqulwa komthelela, ukuze kucutshungulwe kube umkhiqizo owusizo.

I-PVC resin isetshenziselwa ikakhulukazi ukukhiqizwa kwezinhlobo ezahlukene zefilimu elincanyana (njengefilimu yokunyathelisa yansuku zonke, ifilimu yokupakisha yezimboni, ifilimu ye-greenhouse yezolimo, ifilimu eshisayo eshisayo, njll.), zonke izinhlobo zepuleti, ishidi, ishidi lingasetshenziswa imikhiqizo yamabhamuza), zonke izinhlobo zamapayipi, njengokungewona ubuthi epayipini lokucupha amapayipi, ipayipi elibonisa ngale, njll.), zonke izinhlobo zezinto ezimise okukhethekile, njengomnyango, iwindi, ipuleti lokuhlobisa, ibhodlela elingenalutho (izimonyo nezimonyo iziphuzo), Ikhebula, zonke izinhlobo zemikhiqizo yomjovo nesikhumba sokwenziwa, isikhumba saphansi, amathoyizi epulasitiki, njll.

I-Zibo Junhai Chemical iyi-ejenti yokuqala ye-Sinopec Qilu, uhlobo oluyinhloko lwe-PVC ngokulandelayo.
