Munguva yeplasticization process, calcium zinc stabilizers ine yakakwirira electronegativity, uye acute node dzePVC resin dzine humwe hukama, dzichigadzira yakasimba bond energy complexes.
Calcium zinc stabilizers inogona kukamurwa kuita yakasimba calcium zinc stabilizers uye liquid calcium zinc stabilizers.
Liquid calcium zinc stabilizer inoenderana neresin uye plasticizers, nekujeka kwakanaka, kunaya kwakaderera, kuderera kwedosi, uye kushandisa nyore. Izvo zvakanyanya zvisingabatsiri ihuori husina kunaka uye kuora panguva yekuchengetedza kwenguva refu.
Solid calcium zinc stabilizers inonyanya kuumbwa ne sipo ye stearic acid. Chigadzirwa chacho chinoratidzwa nekunaka kwakanaka uye chakakodzera kugadzirisa yakaoma PVC mapaipi uye profiles
Zvigadzirwa zvakagadziriswa uchishandisa microemulsification tekinoroji zvinokunda izvo zvambotaurwa zvinokanganisa. Tarisa pakuvandudza kubva pamativi maviri: kushandura ruvara rwekutanga, kushandisa huwandu hwakakwana hwesipo yezinc, uye kushandisa mumiriri wemusanganiswa kuita kuti zinc chloride isakuvadze, inova yakakwira zinc yakaoma; Kuderedza huwandu hwesipo yezinc kudzivirira kupisa kwe zinc uye kushandura ruvara rwekutanga nezvinowedzerwa inozivikanwa seyakaderera zinc blending. Haisi kungoshandiswa zvakanyanya muzvigadzirwa zvinyoro, asiwo mukugadzirisa zvinhu zvakaoma.
Calcium zinc stabilizers, nekuda kwekukwirira kwavo kwemagetsi, vane imwe hukama hweacute node dzePVC resin panguva yeplasticization process, vachigadzira yakasimba bond simba macomplexes anonetesa kana kugadzirisa kukwezva kwemaion bond muzvikamu zvakasiyana zvePVC. Izvi zvinoita kuti zvikamu zvakapindirana zvePVC zvive nyore kupararira, uye mapoka emamorekuru anotarirwa kumiganhu miduku, iyo inobatsira kupurasitiki yePVC resin. Kukonzera kuwedzera kwakanyanya kwekunyunguduka kunyunguduka, kunyunguduka
Muviri viscosity inoderera, tembiricha inowedzera, uye kupisa kwepurasitiki kunoderera.
Uye zvakare, sechinyakare PVC kugadzira michina yakagadzirirwa kugadzirisa uchishandisa lead salt stabilizer, kunyangwe iine lubricant yakakwana yakawedzerwa, haigone kudzivirira resin kubva pakuwedzera plasticizing munguva yakakwana, kukanganisa yekutanga lubrication chiyero. Muchikamu chekupedzisira chekushandiswa, PVC inonyunguduka inopedza huwandu hukuru hwekudziya kwekudziya muhomogenization nhanho, asi panguva imwechete haigone kuwana yakanakira viscosity uye elasticity kusangana nekugadzirwa kwezvinodiwa zvePVC yakaoma.
