1. Kodi pepala lokhazikika la PVC?
Dzina lathunthu la PVC Rigid pepala ndi polyvinyl chloride chokhwima. Mapepala okhwima a PVC ali ndi polymer zopangidwa ndi vinyl chloride ngati zida zomera, zolimbitsa thupi, mafuta ndi mafinya ndi mafinya opangidwa ndi mafinya. Ili ndi Super Warkulu antioxidant, acid acid ndi kuchepetsa mphamvu, mphamvu yayikulu, kukhazikika kwabwino, komanso kusakhala ndi chipongwe, ndipo mutha kukana kuwonongeka kwa nyengo. Mapepala wamba a PVC okhwima amaphatikizapo mapepala a PVC, mapepala oyera a PVC, mapepala akuda a PVC, ma sheet a pvc, stack pvc mapepala, etc.
2. Kodi phindu ndi chiyani papepala la RCC PVC?
Ma sheet okhwima a PVC ali ndi zabwino zambiri monga kukana kutukuka, osakhala owoneka bwino, kutchinjiriza, ndi ma oxidation kukana. Kuphatikiza apo, amatha kukwiya komanso kukhala ndi ndalama zochepa. Chifukwa cha kugwiritsa ntchito mitundu yambiri komanso mitengo yotsika mtengo, amakhala gawo la msika wa pulasitiki. Pakadali pano, kusintha kwa dziko lathu ndikusintha ukadaulo wa mapepala a PVC kwafika pamlingo wapadziko lonse lapansi.
3. Kodi ndi chiyani cha pepala la PVC?
Ma sheet a PVC amasinthasintha kwambiri, ndipo pali mitundu yosiyanasiyana ya mapepala a PVC, mapepala a PVC, zobiriwira za PVC, zopangidwa ndi mitengo yotsika, kutunkha kwa mitengo ndi kusokonezeka. Ma sheet a PVC amagwiritsidwa ntchito kwambiri ndipo amagwiritsidwa ntchito popanga: makhadi a PVC, makadi olimba a PVC, mafilimu olimba a PVC, etc.
4. Kodi ndi chiyani chomwe chikuyenera cha pepala la PVC?
Tsamba la PVC lilinso pulasitiki yogwiritsidwa ntchito. Ndiwosautsa wopangidwa ndi polyvinyl chloride utoto, wapulatipumu, ndi antioxidant. Si zoopsa palokha. Koma zinthu zazikuluzikulu monga ma pulasitiki ndi antioxaxaxatestantrants ndi poizoni. Mafupa mu mapulasitiki a PVC tsiku lililonse amagwiritsa ntchito dibutyl terephtate ndi dioctyl PUthate. Mankhwala awa ndi oopsa. Antioxidant Afikire Stearate omwe amagwiritsidwa ntchito pa PVC ndizowopsa. Ma sheet a PVC omwe ali ndi ma antioxidarantrantrantrantrants adzakumana ndi ma sol solt monga ethanol ndi ether. Ma sheet okhala ndi PVC amagwiritsidwa ntchito popanga chakudya. Akakumana ndi timitengo yokazinga, makeke okazinga, nsomba yokazinga, zinthu zophika nyama, zophika ndi zokhwasula, mamolekyulu otsogolera amasokoneza mafuta. Chifukwa chake, matumba apulasitiki a PVC sangagwiritsidwe ntchito kugwirira chakudya, makamaka chakudya chomwe chili ndi mafuta. Kuphatikiza apo, zinthu zapulasitiki za polyvinyl chloride zimawola pang'onopang'ono hydrogen chloride gasi kutentha kwambiri, monga kuzungulira mipweya ya munthu.
