Resin bakeng sa ho hlahisa litlaleho tsa polasetiki tsa PVC ke polyvinyl chloride resin (PVC).Polyvinyl chloride ke polymer e entsoeng ka vinyl chloride monomer.

Resin ea PVC e ka aroloa ka mefuta e 'meli, mofuta o hlephileng (XS) le mofuta o kopanetsoeng (XJ), ho itšetlehile ka moemeli oa ho qhalakanya ho polymerization.Boholo bo hlephileng ba karoloana ke 0.1-0.2mm, bokaholimo ha bo tloaelehe, bo porous, bo tšoana le k'hothone, bo bonolo ho monya polasetiki, boholo ba likaroloana tse nyane bo ka tlase ho 0.1mm, bokaholimo bo tloaelehile, bo tiile, tennis ea tafole, ho thata ho monya plasticizer, At hona joale, mefuta e mengata e hlephileng e sebelisoa.

PVC e ka aroloa ka sehlopha se tloaelehileng (PVC e chefo) le kereiti ea bohloeki (PVC e seng chefo).Boemo ba bohloeki bo hloka vinyl chloride (VC) e ka tlaase ho 10 × 10-6, e ka sebelisoang lijong le meriana.Mekhoa e fapaneng ea maiketsetso, PVC e ka aroloa ka PVC e emisitsoeng le emulsion PVC.Ho ea ka tekanyetso ea naha ea GB/T5761-93 "Tekanyetso ea tlhahlobo ea resin ea polyvinyl chloride e sebelisoang ka kakaretso bakeng sa mokhoa oa ho emisoa", mokhoa oa ho emisa PVC o arotsoe ka PVC-SG1 ho ea ho PVC-SG8 mefuta e robeli ea li-resin, moo palo e nyane haholo. e kholoanyane tekanyo ea polymerization, boima ba molek'hule bo boetse ke Matla a maholoanyane, a phahamisa phallo ea ho qhibiliha, 'me ho thata haholoanyane ho sebetsa.

Ha u khetha sehlahisoa se bonolo, hangata ho sebelisoa PVC-SG1, PVC-SG2, le PVC-SG3, 'me ho hlokahala hore ho eketsoe polasetiki e ngata.Ka mohlala, filimi ea polyvinyl chloride e entsoe ka resin ea SG-2, 'me likarolo tse 50 ho isa ho tse 80 tsa polasetiki li kenngoa.Ha ho sebetsoa lihlahisoa tse thata, li-plasticizers ka kakaretso ha li kenyellelitsoe kapa ha li kenyellelitsoe ka chelete e nyane, kahoo PVC-SG4, PVC-SG5, PVC-SG6, PVC-SG7, le PVC-SG8 li sebelisoa.

Mohlala, resin ea SG-4 e sebelisoa bakeng sa phala e thata ea PVC, resin ea SG-5 e sebelisoa bakeng sa profil ea lemati le fensetere, resin ea SG-6 e sebelisoa bakeng sa filimi e hlakileng e hlakileng, 'me resin ea SG-7 le SG-8 e sebelisetsoa ho etsa mohlala. profil e thata e foamed.Mokhoa oa emulsion oa PVC peista o sebelisoa haholo bakeng sa letlalo la maiketsetso, wallpaper, letlalo la fatše le lihlahisoa tsa polasetiki.Baetsi ba bang ba PVC ba tsamaisa resin ea PVC ho ea ka tekanyo ea polymerization (degree ea polymerization ke palo ea li-unit links, tekanyo ea polymerization e atisitsoeng ke boima ba molek'hule ea ketane e lekana le boima ba molek'hule ea polymer), joalo ka PVC. resin e hlahisoang ke Shandong Qilu Petrochemical Plant, lihlahisoa tsa fektheri Ke S-700;S-800;S-1000;S-1100;S-1200.

Resin ea SG-5 e na le tekanyo ea polymerization ho tloha ho 1,000 ho isa ho 1,100.PVC phofo ke phofo e tšoeu e nang le boima bo pakeng tsa 1.35 le 1.45 g / cm3 le boima bo bonahalang ba 0.4 ho 0.5 g / cm3.Re nka litaba tsa li-plasticizers lihlahisoa tsa PVC e le lihlahisoa tse bonolo le tse thata.Ka kakaretso, lintho tsa polasetiki ke likarolo tse 0 ~ 5 bakeng sa lihlahisoa tse thata, likarolo tse 5 ~ 25 bakeng sa lihlahisoa tse thata, le likarolo tse fetang 25 bakeng sa lihlahisoa tse bonolo.

Zibo Junhai Chemical ke barekisi ba ka sehloohong ba Pvc Resin.Re ka fana ka PVC Resin S3, PVC Resin SG5, PVC Resin SG8, ​​PVC Resin S700, PVC Resin S1000, PVC Resin S1300 ext.'Me e tsoa ho baetsi ba ka holimo ba Chaena, ba kang Erdos PVC Resin, Sinopec PVC Resin, Beiyuan PVC Resin, Xinfa PVC Resin, Zhong tai PVC Resin, Tianye PVC Resin.ext.

Polyvinyl chloride e na le litšobotsi tse hlahelletseng tsa lisebelisoa tse ngata tse tala (oli, lejoe la mokoetla, coke, letsoai le khase ea tlhaho), ts'ebetso ea tlhahiso e holileng, theko e tlase, le mefuta e mengata ea ts'ebeliso.E fetohile resin ea bobeli e kholo ka ho fetisisa lefatšeng ka mor'a polyethylene resin.29% ea kakaretso ea tšebeliso ea lefats'e ea resin ea maiketsetso.Polyvinyl chloride e bonolo ho sebetsa 'me e ka sebetsoa ka ho bōptjoa, ho laminate, ho bōptjoa ka ente, extrusion, calendering, blow molding, joalo-joalo Polyvinyl chloride e sebelisoa haholo-holo ho hlahisa lihlahisoa tse bonolo tsa polasetiki tse kang letlalo la maiketsetso, lifilimi le likhetla tsa terata. e le lihlahisoa tsa polasetiki tse thata tse kang lipoleiti, mamati le lifensetere, lipeipi le li-valve.
