1. Yintoni i-rigid pvc iphepha?
Igama elipheleleyo lephepha le-PVC rigravid yi-Polyviny ye-pigid fible. Iphepha le-PVC le-PVC yimpahla ye-polymer eyenziwe nge-vinyl chloride njengezixhobo eziluhlaza, kunye nezilonda, i-fillers kunye neefilimu ezongeziweyo. Ine-antioxididant ephezulu, i-acid eyomeleleyo kunye nokuncipha kokuncipha, amandla aphezulu, uzinzo olugqibeleleyo kunye nokungafuneki, kwaye kunokuxhathisa ukutshintsha kwemozulu. Amaphepha aqhelekileyo e-PVC aquka amaphepha e-PVC, amaphepha amhlophe e-PVC, amaphepha amnyama e-PVC, amaphepha e-PVC enombala, i-PREC GRECS, njl.
2. Yintoni inzuzo yephepha le-PVC yePVC?
Amaphepha e-PVC ye-PVC anezibonelelo ezininzi ezifana nokuchasana nokunganyangeki, ukungavutha, kunye nokunganyangeki kwe-oxidation. Ukongeza, banokuhlanjwa kwaye babe neendleko zemveliso eziphantsi. Ngenxa yoluhlu lwabo olubanzi lokusetyenziswa kunye namaxabiso afikelelekayo, bahlala behlala kwinxalenye yentengiso yephepha lephepha lephepha lephepha. Okwangoku, ukuphuculwa kwelizwe lethu kunye netekhnoloji yoyilo lweemakhishithi ze-PVC kufikelele kwinqanaba eliphezulu lamanye amazwe.
3. Uyintoni umsebenzi wephepha le-PVC?
Iphepha le-PVC liguqulela kakhulu, kwaye kukho iintlobo ezahlukeneyo zephepha le-PVC, ezinje ngephepha le-PVC, ii-PVC ze-PVC ezinamaphepha, iindleko eziphantsi zePVC, iindleko eziphantsi ze-PVC, ukuxhaphaza kwemveliso ephantsi, ukuxhaphaza kwemveliso ephantsi, ukuxhaphaza kwemveliso ephantsi, ukuxhaphaza kwemveliso ephantsi, ukuxhaphaza kwemveliso ephantsi, ukuxhaphaza kwemveliso. Amaphepha e-PVC asetyenziswa ngokubanzi kwaye asetyenziselwa ukulungelelaniswa kwezenziweyo: I-PVC yokubopha i-PVC, amakhadi e-PVC, iifilimu ze-PVC, ii-PVC ezinzima, amaphepha e-PVC, njl.
4. Yintoni eyona nto iphosakeleyo kwiphepha le-PVC?
Iphepha le-PVC likwiplastiki esetyenziswayo. Yindawo yokuphinda idityaniswe nge-polyvinyl chloride, iplastiki, kunye ne-antioxidant. Ayisiyotyhefu ngokwayo. Kodwa ezona zinto zincedisayo ziphambili ezinjengo-pristizers kunye nee-antioxidants zinetyhefu. Iplastiki kwi-PVS ye-PVC yephepha le-PVC ikakhulu isebenzisa ikakhulu i-Dicken Tereph heart kunye ne-dioctyl phthalate. Ezi khemikhali zinetyhefu. I-Antioxidant ikhokelele i-steate esetyenziswe kwi-PVC nayo inetyhefu. Amaphepha e-PVC equkethe i-Antiootionals ekhokelela ekuqhubeni xa enxibelelana nezinyibilikisi ezinje nge-ethanol kunye ne-ether. I-Comphes-enemakhishithi ye-PVC isetyenziselwa ukupakishwa kokutya. Xa badibana nezinti ezityebileyo, iikeyiki ezithosiweyo, intlanzi ephosiweyo, iimveliso zenyama eziphekiweyo, iivenkile eziphekwe yinyama, njl., Iimolekyuli zikhokelela kwioyile. Ke ngoko, iingxowa zeplastiki zePVC azinakusetyenziselwa ukubamba ukutya, ngakumbi ukutya kweoyile. Ukongeza, i-polyvinyl i-chloriny yeplastiki iya kuhamba kancinci i-hydrogen irhasi ye-hydrogen kwiqondo elingaphezulu, njengama-50 ° C, elinobungozi emzimbeni womntu.
