1) Kunwisa uye kudzikamisa HCL, kudzivirira auto catalytic effect yayo. Rudzi urwu rwe stabilizer runosanganisira lead salts, organic acid metal sipo, organotin compounds, epoxy compounds, inorganic salts, uye metal thiol salts. Zvinogona kuita neHCL uye kudzivirira reaction yePVC kubvisa HCL.
2) Kutsiva maatomu echlorine asina kugadzikana mumamorekuru ePVC kunodzivirira kubviswa kweHCL. Kana organic tin stabilizer ikabatana nemaatomu echlorine asina kugadzikana emamorekuru ePVC, organic tin ichatsiviwa nemaatomu echlorine asina kugadzikana ari mumuviri wekubatana.
3) Kubatanidzwa kwe polyene kunovhiringidza kuumbwa kwehurongwa hwakakura hwakasanganiswa uye kunoderedza ruvara. Unsaturated acid salts kana esters dzine ma double bonds, ayo anopindirana ne diene addition reaction nema PVC molecules nekubatanidza ma double bonds, nokudaro zvichikanganisa ma conjugated structure avo uye zvinodzivisa kuchinja kweruvara.
4) Kubata mafree radicals nekudzivirira oxidation reactions, iyi thermal stabilizer inogona kuva nemhedzisiro imwe kana dzakawanda.
Chinhu chakakodzera chePVC chinogadzirisa kupisa chinofanira kunge chiri chinhu chinoshanda zvakawanda kana musanganiswa wezvinhu zvinogona kuita mabasa anotevera: chekutanga, kutsiva zvinhu zvinoshanda uye zvisina kugadzikana; Chechipiri ndechekunyudza nekubvisa HCL inoburitswa panguva yekugadzirisa PVC, kubvisa otomatiki catalytic degradation effect yeHCL; Chechitatu ndechekubvisa kana kusunungura ma ions esimbi nezvimwe zvinhu zvinokuvadza zvinoita basa re catalytic mukuora; Chechina, mhando dzakasiyana dzemakemikari dzinogona kudzivirira kukura kuri kuramba kuchienderera kwezvisungo zvisina kuzara uye kudzivirira kuora kwemavara; Cheshanu, ine mhedzisiro yekudzivirira uye yekudzivirira pachiedza che ultraviolet. Kazhinji, zvinogadzirisa kupisa zvinoshandiswa pamwe chete zvichienderana nekushanda kwazvo, uye kushandiswa kwazvo kwega kwega hakuwanzoitiki. Uyezve, mhando zhinji dziri muchimiro cheupfu, dzimwe dziri makemikari ane chepfu yakanyanya. Kuti zvive nyore kushandisa, kudzivirira chepfu yeguruva, kuderedza zvinhu zvine chepfu kana kuzvitsiva nezvinhu zvisina chepfu, mhando dzakawanda dzezvinogadzirisa zvakagadzirwa munyika nepasi rese mumakore achangopfuura. Semuenzaniso, mhando yeGerman Bear composite stabilizer series, pamwe chete neorganic tin kana composite organic tin stabilizers kubva kunyika dzakadai seUnited States, Germany, Japan, neNetherlands, zvese zvine musika wakakura muChina. Nokudaro, zvakakosha kuti indasitiri yepurasitiki yeChina ivandudze zvizere kushandiswa kwecomposite stabilizers itsva dzinoshanda zvakanaka, dzisingadhuri, dzisina guruva, dzisina chepfu kana dzisina chepfu.
