Resin yePolyvinyl chloride (PVC), sezvinoreva zita racho, resin iyi inonyanya kushandiswa muchimiro chekunamira. Vanhu vanowanzo shandisa rudzi urwu rwekunamira seplastisol, inova rudzi rwakasiyana rwepurasitiki yePVC isina kugadzirwa. . Maresini ekunamira anowanzo gadzirwa nenzira dze emulsion uye micro-suspension.
Polyvinyl chloride paste resin ine saizi yakanaka, uye magadzirirwo ayo akaita setalc, isingafambi. Polyvinyl chloride paste resin inosanganiswa nePlasticizer yozosanganiswa kuti iite stable suspension, iyo inozogadzirwa PVC paste, kana PVC plastisol, PVC sol, uye ndiyo nzira iyi iyo vanhu vanoshandiswa kugadzirisa Zvigadzirwa zvekupedzisira. Mukugadzira paste, mafiller akasiyana-siyana, diluents, heat stabilizers, furo agents uye light stabilizers zvinowedzerwa zvichienderana nezvinodiwa nezvigadzirwa zvakasiyana.
Kuvandudzwa kweindasitiri yePVC paste resin kunopa mhando itsva yezvinhu zvine mvura zvinova chigadzirwa chepolyvinyl chloride chete nekudziya. Rudzi urwu rwezvinhu zvine mvura zviri nyore kugadzirisa, zvakagadzikana pakushanda, zviri nyore kudzora, zviri nyore kushandisa, zvakanaka pakushanda kwechigadzirwa, zvakanaka pakushanda kwemakemikari, zvine simba remuchina, zviri nyore kupenda, nezvimwewo, saka zvinoshandiswa zvakanyanya muganda rekugadzira, matoyi evinyl, zviratidzo zvekutengeserana zvakapfava, Kugadzirwa kwemadziro emadziro, pendi nependi, mapurasitiki ane furo, nezvimwewo.
Pfuma：
PVC paste resin (PVC) imhando yakakura yema polyvinyl chloride resins. Kana ichienzaniswa nema suspension resins, ihupfu hunopararira zvakanyanya. Hukuru hwe particles hunowanzova 0.1 ~ 2.0μm (kupararira kwe particles yema suspension resins kunowanzova 20 ~ 200μm. ). PVC paste resin yakatsvakurudzwa paIG Farben fekitori muGermany muna 1931, uye kugadzirwa kwemaindasitiri kwakaitwa muna 1937.
Mumakore makumi mashanu apfuura, indasitiri yepasi rose yePaste Pvc Resin yakawedzera nekukurumidza. Kunyanya mumakore gumi apfuura, kugona kwekugadzira nekugadzira kwakaratidza kukura kukuru, kunyanya muAsia. Muna 2008, kugona kwekugadzira pasi rose kwePaste PVC resin kwaive matani angangoita mamiriyoni 3.742 pagore, uye kugona kwekugadzira muAsia kwaive matani angangoita 918,000, zvichiita 24.5% yesimba rese rekugadzira. China ndiyo nzvimbo iri kukura nekukurumidza muindasitiri yePaste PVC resin, ine kugona kwekugadzira kwaive neanenge 13.4% yesimba rese rekugadzira pasi rose uye inenge 57.6% yesimba rese rekugadzira muAsia. Ndiyo mugadziri mukuru muAsia. Muna 2008, kugona kwePaste PVC resin pasi rose kwaive matani angangoita mamiriyoni 3.09, uye China yaiburitsa matani 380,000, zvichiita 12.3% yesimba rese rekugadzira pasi rose. Kugona kwekugadzira nekugadzira kuri pachinzvimbo chechitatu pasi rose.
