1、 Vatongi vePVC vanofema vanogona kuchinja hunhu hwavo kana vakaiswa pakupisa, saka vanofanirwa kuchengetedzwa kure nemoto, mapaipi ekupisa, maheater, kana zvimwe zvinhu zvinopisa. Kuwedzera vatongi vePVC vanofema kunogona kukonzera guruva, uye kana guruva rikasangana nemaziso kana ganda, rinogona kukonzera kukuvara kukuru mumuviri. Saka, zvakakosha kudzivirira kugadzira guruva panguva yekugadzirisa. Kana rikapinda mumaziso netsaona kana rikasangana neganda, tinofanira kurirapa nemvura nekukurumidza.
2、 Kuwedzerwa kwePVC foaming regulator kunovandudza simba rekunyunguduka, kudzivirira kubatana kwemabubbles, uye kuita kuti furo rive rakafanana. Wana zvigadzirwa zvePVC foam zviri nani. PVC foaming regulators inogona kukurudzira plasticization yePVC uye kuona kuti kuyerera kwakanaka.
3. Pakusarudza vanodzora furo rePVC, kungwarira kunofanirwa kupihwa pakusarudza vanodzora furo vakasiyana vePVC vane madhigirii akasiyana epolymerization, akadai sePVC-700, PVC-800, uye PVC-1000. Zvigadzirwa zvakasiyana, zvakaita sefoam board, foam thin board, foam board yemapuranga, lead plastic foam board, nezvimwewo, zvinoda kushandisa vanodzora furo vakasiyana. Nekuda kwekuti PVC foaming aids zvakare acrylic ester substances dzine processing aid properties, kutarisisa kunofanirwawo kupihwa kune internal neexternal lubrication balance yeformula pakushandisa.
