ntchito

I. Makhalidwe azinthu:

PVC amapangidwa ndi vinilu kolorayidi monoma (VCM) polymerization, PVC zinthu ali sanali poizoni, odana ndi ukalamba ndi asidi ndi alkali kukana makhalidwe, choncho ndi abwino kwambiri ntchito payipi mankhwala.Ndipo ndi PVC zopangira kuwonjezera kuchuluka kwa zina olimba zina (palibe plasticizer) zikuchokera osakaniza otchedwa olimba polyvinyl kolorayidi (wotchedwa UPVC).

CPVC ndi polima zinthu kusinthidwa ndi chlorination wa polyvinyl kolorayidi (PVC) kachiwiri.Pambuyo klorini, chlorine zili PVC utomoni ukuwonjezeka kuchokera 56.7% kuti 63-69%, amene kumawonjezera kukhazikika kwa mankhwala ndipo motero bwino kutentha kukana ndi dzimbiri kukana asidi, zamchere, mchere ndi okosijeni wa zakuthupi.Kutentha kwake kwamafuta ndi makina amakina ndizokwera kwambiri kuposa za UPVC.Chifukwa chake, CPVC ndi imodzi mwazinthu zopangira uinjiniya wamapaipi amakampani.

2. Chiyambi cha dongosolo la mapaipi:

Dongosolo la mapaipi a UPVC ndi CPVC ali ndi kukana kwa dzimbiri, kukana kwamphamvu, kosavuta kupindika, khoma losalala lamkati, losavuta kukulitsa, kutchinjiriza kwamafuta abwino, osayendetsa bwino, kulumikizana kosavuta, moyo wautali wautumiki ndi zina.Choncho, pang'onopang'ono imalowa m'malo mwa machitidwe ena azitsulo zazitsulo pa ubwino wa ntchito zamtengo wapatali ndi mtengo wotsika mtengo womanga, ndi UPVC ndi CPVC makina opangira mapaipi ndi abwino komanso okonzekera mwamsanga, popanda nthawi yayitali komanso kutayika kwakukulu, kotero UPVC ndi CPVC mapaipi ndi njira yoyamba. kwa mapangidwe amakono a mapaipi amakampani.

Kutentha kovomerezeka kovomerezeka kwa UPVC mapaipi ndi 60 ℃, ndipo kutentha kwanthawi yayitali ndi 45 ℃.Ndizoyenera kunyamula media zowononga ndi kutentha kochepera 45 ℃;Angagwiritsidwenso ntchito mayendedwe wamba kuthamanga madzimadzi, ambiri ntchito madzi ndi ngalande mapaipi, mipope ulimi ulimi wothirira, mapaipi zachilengedwe zomangamanga, mapaipi mpweya woziziritsa ndi zina zotero.

Kutentha kovomerezeka kwautumiki wa CPVC mapaipi ndi 110 ℃, ndipo kutentha kwanthawi yayitali ndi 95 ℃.Ndioyenera kutumizira madzi otentha ndi zotengera zowononga mkati mwa mayendedwe ovomerezeka a muyezo.Nthawi zambiri ntchito mafuta, mankhwala, zamagetsi, magetsi, zitsulo, mapepala, chakudya ndi chakumwa, mankhwala, electroplating ndi minda ina mafakitale.
