PVC utomoni kwa shrinkable filimu
PVC utomoni wa filimu shrinkable,
PVC utomoni SG7, Kuyimitsidwa kwa PVC SG7,
Imakhala ndi pulasitiki ya thermo, yosasungunuka m'madzi, petulo ndi mowa, yotupa kapena kusungunuka mu ether, ketone, chlorinated aliphatic hydrocarbons, ndi mafuta onunkhira a hydrocarbon, kukana dzimbiri, komanso katundu wabwino wa dielectric.

Mapulogalamu
*SG-1 imagwiritsidwa ntchito popanga zida zoyatsira magetsi zapamwamba kwambiri
* SG-2 imagwiritsidwa ntchito popanga zida zotchingira magetsi, zinthu zofewa wamba komanso filimu
*SG-3 imagwiritsidwa ntchito popanga zida zamagetsi zamagetsi, filimu yaulimi, zinthu zamapulasitiki zomwe zimagwiritsidwa ntchito tsiku ndi tsiku, monga
monga Mafilimu, malaya amvula, kulongedza mafakitale, zikopa zopangira, payipi ndi zinthu zopangira nsapato, etc.
*SG-4 imagwiritsidwa ntchito popanga membranelle kuti igwiritsidwe ntchito m'mafakitale ndi anthu, chubu ndi mapaipi

Pakuti zolimba PVC shrinkable filimu, ndi bwino ntchito kuyimitsidwa mtundu 6 kapena 7 utomoni, ngakhale mu waya ndi chingwe kugwirizana ndi shrinkable filimu, resistivity wa thupi si mkulu monga 2 kapena 3 utomoni, koma 7 utomoni akamaumba, kupanga. mchitidwe watsimikizira kuti ntchito 2 kapena 3 utomoni, n'zovuta kupanga, zolimba PVC shrinkable filimu kupanga molimba ndi Chimaona, sangathe apangidwe ndi adagulung'undisa.
Pogwiritsira ntchito pulasitiki, kutentha kwa kutentha kumachepa ndi kuwonjezeka kwa zinthu za plasticizer.Mwachitsanzo, kugwiritsa ntchito suspending mtundu 3 PVC mtengo mafuta ufa, kuwonjezera DOP plasticizer of30-50 PHR, akhoza biaxial kumakoka pafupifupi 70 ℃, ndipo mankhwala ake akhoza kuotcha pafupifupi 40 ℃, osakhoza kusungidwa mu masiku otentha.Kuphatikiza apo, pakuwonjezeka kwa zinthu za plasticizer, mphamvu yolimbana ndi kutentha kwa waya ndi chingwe imachepa.Choncho, tikamagwiritsa ntchito mawotchi a PVC omwe amatha kutentha kutentha kwa waya ndi chingwe, timagwiritsabe ntchito ma resin amtundu wa 6 kapena 7 omwe ndi osavuta kukonza.Kuti tipititse patsogolo kutsekemera, timagwiritsa ntchito stabilizer yotentha pamodzi ndi mchere atatu ndi mchere awiri ndikuwongolera moyenerera makulidwe a filimu kuti atsimikizire kuti kutsekemera.P83 nitrile mphira ali machinability wabwino, elasticity, kukana ozizira, ndipo akhoza kusintha mphamvu, kusintha maganizo akulimbana kukana PVC mankhwala.Active CaCO3 makamaka imapangitsa kuti zinthu zisamayende bwino komanso kuchedwa kwamoto komanso kumachepetsa mtengo wake.
