Ithumbu lePVC elomeleziweyoyimveliso engenakwahlulwa ebomini bethu.Kukho iintlobo ezininzi of PVC imibhobho.Phakathi kwazo, iimveliso ezisebenzisa irabha yethu engumgubo ye-nitrile i-P8300 ibandakanya i-PVC yoxinzelelo oluphezulu lwemibhobho yomoya, i-hoses ye-oksijini yoxinzelelo oluphezulu, kunye nemibhobho yegesi yendalo yasekhaya / yamashishini., imibhobho yegesi enyibilikisiweyo, imibhobho yerhasi, imibhobho yokutshiza yezolimo enoxinzelelo oluphezulu yePVC, imibhobho yokuntywila enoxinzelelo oluphezulu, imibhobho yerhasi enombala ethambileyo, imibhobho yeoli ekwaziyo ukumelana nobushushu obuphezulu, kunye nemibhobho yomlilo, njl. njl., masiyiququzelele wonke umntu!Khumbula ukuthatha incwadi encinci kwaye uyibhale phantsi ~
Uyibiza njani i-hose ye-PVC eqinisiweyo, iimfuno zayo kufuneka ubuncinane zihlangabezane nezi mpawu zisisiseko: ukuxhathisa uxinzelelo oluphezulu, ukumelana nokwaluphala, ukuxhathisa ukunxiba, ukuthamba kunye nokuqina, ukuxhathisa ukudonsa, ukuxhathisa ukungcangcazela, ukumelana nokubanda, ukuxhathisa ukubola, ukuxhathisa kwe-asidi kunye ne-alkali, i-flame retardant , Imveliso ayithambilenga xa ishushu, ilula kwaye ihlala ihlala njalo.
Nangona kunjalo, i-hoses eqinisiweyo ye-PVC eveliswa ngabavelisi abaninzi ayinakuhlangabezana nezi zakhiwo zisisiseko konke konke.Endaweni yoko, kuya kubakho iingxaki ezahlukeneyo, ezifana ne-oven ayikwazi ukumelana nobushushu obuphezulu kunye nokugqabhuka, uvavanyo lwe-oven tensile alwanelanga, njl. Kakade ke, ngaphezu kwenkqubo yokuvelisa, ulawulo lobushushu, isantya se-Extrusion, njl. eyona nto ibaluleke kakhulu kukukhetha imathiriyeli ekrwada eyiyo.Eyona nto iphambili kwimveliso yeIthumbu lePVC elomeleziweyoyi polyvinyl chloride (PVC) resin.I-PVC ngokwayo ayinayo i-elastic kunye ne-flexible chain structure, ngoko ke ukumelana nobushushu obuphantsi bubi.Irabha ye-nitrile engumgubo i-NBR-P8300, njenge-elastomer, inomlinganiselo ophezulu wokuhambelana ne-PVC, kwaye yenza isakhiwo "sesiqithi" xa sihlanganiswe nePVC.Le nkqubo yokuxuba iyunifomu inokuphucula ngokufanelekileyo ukuguquguquka kwe-PVC, kunye nokuchasana kwayo okuphantsi kweqondo lokushisa kunokuphuculwa.Ukuphucuka okusebenzayo, ngenxa yeengqungquthela zayo ezintle, ukusabalalisa okulungileyo kunye nokunyuka kwamanzi, iindawo ezithambileyo zeerubha kunye ne-elastomers zisasazwa ngokufanayo kwizinto ezixubeneyo, ngaloo ndlela zinciphisa ukugqoka kunye nokukrazula kweemveliso ezithambileyo ze-PVC.
Ukusetyenziswa kwerabha ye-nitrile engumgubo i-P8300 nayo iluncedo olukhulu ekuzinzeni kwe-plasticizer.Uninzi lweeplasticizers ezisetyenziswa kwi-PVC ethambileyo zizinto eziphantsi-molekyuli, kwaye iimveliso zivame ukutshiza ioli, iibhokisi zokutshiza, kunye nokutshiza ngexesha lokusetyenziswa.Kwaye ezinye iingxaki, ukongeza i-PNBR kunokunyusa ukomelela kwemveliso, ukunciphisa inani le-plasticizer esetyenzisiweyo, kwaye kwangaxeshanye kuncitshiswe isantya sokufuduka kweplasitiki ngenxa yomtsalane weplasitiki.
